Title: Soyuz-2-1v Launcher (formerly Soyuz-1)
Post by: zaitcev on 04/11/2009 01:18 am

Quote
Активно ведётся разработка нового носителя лёгкого класса «Союз-1»
Which means, "New Light LV Soyuz-1 is being actively designed/developed".

I think I heard about that thing before. Supposedly it's Soyuz-ST without the iconic side strap-ons. A weird idea of an unclear utility, but what do I know.

Which is? Strapping 30 of them together with bad propellant plumbing and no static hold-down tests before actual flight attempts is the engines' fault?

Wow.  Angara seems to be less and less turning out to be Russia's universal launcher.  This treads right on top of the Angara 1 class.

And what about those NK33 engines?  Either they'll have to restart production, or the current stock of engines will be rapidly used up (thwarting Taurus II?).  A restarted production line would, it seems to me, make U.S. production by Aerojet even less likely than currently seems possible.

Assuming anyone wants to buy flights on it.  3 tons is size range of  Delta II Med-Lite variants and the Tsyklon/R-36.  This payload class has recently seen two or three launches a year, one or two from NASA and one from someone else.

It's also hard to say how real this is - "a draft design has been developed" is pretty vague.  ATK has draft designs for their SRB-derived launch vehicles that will are very unlikely to see the light of day.

It's not a bad idea for a LV in this size class, as it involves only one new engine-stage integration task.

Considering only the Russian/CIS launches, which this vehicle would presumably be designed to serve, there were an average of 5.7 launches per year (total 51), from 2000 to 2008 inclusive, of Tsyklon/Dnepr, Rokot, and Kosmos 3M launch vehicles.  That's a sustainable "market" for one launch vehicle, which I presumed was planned to be Angara 1.  Two launch vehicles might be too many for Russia's needs.

Seems to be a possibly resurgent battle brewing for the Russian launch business.

I agree the curse was mostly the lack of a static hold down test.
 The Saturn V probably would have exploded just as badly as the N1 if they tried to fly it without static hold-down testing.

Interesting they would design a light version of Soyuz.

All of those rockets are coming up on retirement (except the Tsyklon, which has already gone), so replacement seems to make sense. My guess is they don't want to put all their eggs in one basket, so they're developing two rockets like the US Air Force did with the EELV programme.

The logical explanation to me is that Samara (TSKB Progress) and Khrunichev (and their supporters in government) are having a public fight over who takes over the manned and small-medium LV space. It wouldn't be the first time that such public announcements were actually a reflection of an internal power struggle.

Samara has had the manned launch market all to themselves, but if a new manned launch complex is built, there's a very real possibility it would only support Angara. If Baikonur closes down, Soyuz could be relegated to a being a minor player, with a few launches from Kourou and maybe some legacy payloads from Plestesk that don't switch to Angara.

EELV style assured access would be a big change of policy. The Russian/Soviet program typically doesn't do long stand downs after failures (these are usually by multiple similar failures indicating a design flaw, and even then the RTF is pretty quick by US standards). Although they've had a wide variety of LVs available, AFAIK most of their national security payloads tend been tied to a particular one. The time to switch LVs could easily be longer than a stand down due to failure. Given the US experience with the EELVs, it's not at all clear this something an objective observer would rush duplicate.

With the retirement of various ICMB based launchers, Russia will need something to replace them, but the proposed "Soyuz 1" is right in the same range as Angara 1.1 and 1.2.

It appears that Russia intends to develop the far east Vostochny launch site to host both manned and unmanned launches as a long-term Baikonur replacement.  Based on recent news, it seems likely that the site will end up handling most of Russia's launch vehicles, and probably most or all of its launch vehicle manufacturers.

This makes the A1.1 not a priority Khrunichev is directed to/or is perusing.  I think they are going for A5 from get go as the demonstration of 'Proton replacement' part, because that's the primary role/capability they are designing the Angara is for.  Once/if that  works... who knows they may come back to A1.1, A3
AFAIK the current test articles are representative of A1, and according to this thread http://forum.nasaspaceflight.com/index.php?topic=3321.0 A1.1 will fly first. Starting with a single core and existing upper stage certainly makes sense from a development POV.

Unless they are short on production capacity, it's hard to see why they wouldn't go after some of the Kosmos/Dnepr/Tsyklon market while they are at it.
Title: Re: Soyuz-1 Launcher
Post by: patchfree on 04/13/2009 02:09 pm
The recent decision to entrust TsSKB Progress with the development and manufacturing of the rocket for the PPTS project could largely change the deal.
TsSKB Progress will be very busy with such a challenge while Soyouz-1 was viewed in a prospective of several upgrades of Soyouz LV for PPTS. Now with the decision to start from skech with a entirely new LV, such new LV can also have a light version. So probably Soyouz-1 will be canceled.
On the side of Khrunitchev, no doubt the Angara 1 will  be the first one developped (first flight will be as such a version) and all the versions will be usable as it's the global rational of this LV complex: using the same pad for all versions and choosing version according to payload.
Title: Re: Soyuz-1 Launcher
Post by: zaitcev on 04/14/2009 01:23 am
I'd like to agree with Patchfree regarding high probability of Soyuz-1 (and Soyuz-2-3 -- same core) being pushed aside while resources are directed at the "new" rocket (tentatively named "Rus'", once again).

Still, two more points:

- Interviews with Klimov' "CEO" Sergey Tresvyatsky mentioned in 2006 or 2007 that they were working on a version of NK-33-1 with roll control, necessary for both Soyuz-1 and Soyuz-2-3 (for a flight after separation of boosters). I don't have links, sorry. They were "about" to run test fires, and also mentioned that they were paying for the development themselves as in "investment".

- Arguing about Angara at Novosti Kosmonavtiki forums is ugly even for Russians, not generally known for politeness. Apparently, Khrunichev's ability to slip schedules puts SpaceX to shame; rumors circulate about issues with guidance system and other components. It's possible that someone in the government decided that giving each sister an earring were prudent.

Post by: yinzer on 04/14/2009 09:55 am
It's clear that the Russians don't want to use the Ukrainian-made Tsyklon/Dnepr if they can help it.  Cosmos-3M gets the most use by the Russian military and is on the verge of retirement, but at 1500kg to LEO is less than half the size of the proposed Soyuz-1.  Anatoly Zak reports that Krunichev was trying to retire Cosmos in favor of the new Angara (shades of Atlas III), but Angara has been delayed so apparently Rockot will be used to fill the gap.  Rockot is based off of a now out-of-production ICBM, but with over 100 left, there shouldn't be much worry of running out any time soon.  It's also in the less than 2000 kg to LEO range.

Interestingly enough, most of the launches by Cosmos/Rockot/Tsyklon/Dnepr in the past few years have been for non-Russian-military customers.  It's unclear how much Angara or Soyuz 1 will cost, but it seems fair to expect that they'd cost more than the converted ICBMs or the 40-year-old Cosmos-3M.  Commercial customers may go elsewhere (Long March?).  Vega should also fly this year, and can reasonably be expected to capture the European government payloads.

Amongst all this, Samara and Energia grabbed the follow-on human launcher contract from Angara 5, and now seem to be targeting the Angara 1 as well.  It'll be interesting to see how it shakes out.

That would be very nice to keep vehicle manufacturers closer to the launch site. That would theoretically allow them to drop that 3.9m-4.1m meter diameter restriction in favour of bigger sizes.

It is interesting that the configuration of Soyuz-1 is not defined till now definitively. For comparison:

This probably should have its own thread.

Title: Re: Soyuz-1 Launch Vehicle in Development
Post by: Danderman on 11/26/2009 03:06 pm
Here is the significance of Soyuz-1:

There are a few potential Soyuz replacement/upgrades out there:

Angara
Soyuz 2-3
Soyuz 3

The first is a Khrunichev product, wildly behind schedule, but nearing flight status. Some potential configurations of Angara have the capability of replacing Soyuz.

Soyuz 2-3 is an evolutionary upgrade of the standard Soyuz, similar to Soyuz 2.1b, but with a larger core using an NK-33 engine. This core is virtually identical to the Soyuz-1 core.

Soyuz 3 is basically a totally new vehicle, similar to Angara, using the RD-180 rather than RD-191 engine, so that the core is twice as powerful as Angara.

As Soyuz 2-3 is one of the three options, if Soyuz-1 is not funded, its likely that Soyuz 2-3 will not be funded, either, leaving the future open to Angara vs Soyuz 3 vs whatever other concept appears in the future.
Title: Re: Soyuz-1 Launcher
Post by: Danderman on 01/28/2010 12:42 am

There is now a launch of Soyuz 1 (a/k/a Soyuz 2.1V) scheduled for 2011. This means that there will now be two new LVs using NK-33s scheduled for first launch about 2011-12. This probably means that the two will collide during launch, since the NK-33 is a cursed engine. Or else, NASA will cancel Taurus II because Soyuz 1 can do the job, and Roskosmos will cancel Soyuz 1, since Taurus II can do its job.

The silly thing is getting fatter and fatter in every iteration. Another change is the more detailed design for the lower arm extensions, which now attaches to the rocket at the force rib at the base of the tankage (old designs had them attached at the bottom of the Tail Section, which obviously made way less sense). So the project is rumbling along, slowly.

Lenta.ru quotes Director-General of TsKB Progress, Alexander Kirillin:

Quote
Первый старт новой легкой ракеты-носителя космического назначения "Союз-2-1В" запланирован на конец 2011 года с космодрома Плесецк.

По словам Кирилина, все договоренности по запуску "Союза-2-1В" уже обсуждены. "Подписаны контракты по двигателю НК-33, системе управления, телеметрии, по всем составляющим", - добавил он. На 17-18 июня 2010 года назначена защита дополнений по эскизному проекту.

Danderman's link above said "early 2011", but it's "the end of 2011" now.

The RD-0110R engine is not mentioned in the article, but I suppose the scope was too rough. What "alterations/additions to the Preliminary Design" Mr. Kirillin is talking about is unknown, but I suspect the diameter gets is increased yet again or something of that nature.

Curiously, the website of Progress (samspace.ru) continues to list "Soyuz-1" instead of Soyuz-2-1v.

The Tail Compartment (Хвостовой Отсек) is actually a structural element. Lower support arms link to it at the launch position, so it takes side loads. Also, RD-0110R engine is attached to it and so the TC transmits about 11 tonne-force of thrust in flight. So TC is not merely an envelope.

It depends on the configuration.  IIRC, there was a configuration which retained the four boosters, which was more than sufficient for crew launch.

That would enable both the Soyuz manned capsule and Progress unmanned.  Otherwise, however, it would fit a similar payload point as Falcon 9, Taurus II and Delta II.

Mostly it's going to keep up with the growth in satellite mass in the same class that Soyuz-ST currently launches to GTO. Lavochkin is carrying out enhancements to Fregat that could be useful on Soyuz-2-3 as well.

Crewed transport on Soyuz-2-3 is so far down horizon, I am not even going to consider it. It is just as likely that PTK will enter service before it, thus rendering the question moot. Not sure if TsSKB or RKKE asked Roskosmos to move crewed launch to Soyuz-2, and Roskosmos refused -- in part because Soyuz-FG is not insignificantly cheaper.

Note that Mr. Zak did not keep up with the news on the Soyuz-2-1V project. He still calls it "Soyuz-1" and lists NK-33-1 as propulsion, which was abandoned back in 2008.

P.S. Note that, according to KBOM, the maximum carrying capacity of R-7 launch pad is about 400 tonnes. The improvements in Isp that NK-33 brings help a bit but basically the carrier is at its capacity for a design in Soyuz-3 class (unless they replace Blok I with a hydrogen stage). There is no growth head. This may be different for Kourou pad though.

The larger issue is that Soyuz cannot really take advantage of the additional capacity offered by Soyuz-2 without a major redesign.

I presume this is the 750 kg Glonass K payload. Since Soyuz-2 can launch 2 of them at a time, it is reasonable to assume that Soyuz-1 can launch one at a time, with the appropriate upper stage.

Note that Mr. Zak did not keep up with the news on the Soyuz-2-1V project. He still calls it "Soyuz-1" and lists NK-33-1 as propulsion, which was abandoned back in 2008.
I see the NK-33-1 still listed in Samara site. What will they use instead? Regrettably I don't speak russian and thus can't keep up with the latest news.

What engine will Volga use? The Volga charts describe an engine with similar characteristics as the Ikar engine.

Its basically an Ikar stage, with about half the dry mass.  Ikar is/was basically a copy of a Soyuz PAO.  So, if you ever need a half sized Soyuz PAO, there you go.
Soyuz-TMA engine (S5.80) has а specific impulse 302 s.
Ikar/Volga engine has а specific impulse 307 s.

First off, it appears from your posts that Volga shares the same engine with Ikar, which is good to know.

Secondly, my suggestion is that Ikar is a copy of the Soyuz PAO from a functional perspective, it is not a duplicate.  It has about the same mass, the same propellant load, about the same engine, about the same size, can be fuelled using the same facilities as the Soyuz PAO, etc.

What is interesting is that Volga duplicates Ikar functionality at half the dry mass of Ikar, which has implications for Soyuz.

I don't know how you can compare them like that. For one thing the mission duration is drastically different, which is why Soyuz PAO carries solar arrays and radiators.

You are correct, Volga is more of a replacement for Ikar than the Soyuz PAO.  However, even Ikar is modified for long duration missions, so I would imagine that the same would be true for Volga.

Again, Ikar is functionally similar to the Soyuz PAO - and they have a very high degree of commonality at the subsystem level. We have see that Ikar can be fitted with solar panels and a thermal conditioning system for very long mission durations (in its Yantar variant).

I suspect that Ikar/Yantar were developed by Samara after their efforts to develop a Soyuz derivative were cancelled, but based on the experience of engineering those vehicles (such as Soyuz 7K-VI).

Russian Space Forces on March 24 celebrates 10 anniversary of the establishment of this kind of troops.

"This year, plans to begin flight tests of rocket light-class Soyuz-1", - he said.

For flight tests of the carrier rocket Soyuz-1 "for several years, is intended to hold five launches.

"All of launch vehicles will be from existing launch facilities after minor improvements related to the overall and weight and design features of the rocket," - "Zolotukhin said.

"Soyuz-1" - a two-stage booster is an easy class, intended for launching spacecraft from the launch complex of the Soyuz-2 ".

Based on what an insider has been writing on the NK forum in the past few days, the first flight vehicle is still in the factory in Samara, but expected to be shipped to Plesetsk shortly.
http://www.novosti-kosmonavtiki.ru/phpBB2/viewtopic.php?t=9953&start=2280

I'm not sure how long it takes to ship the rocket from Samara to Plesetsk, but doesn't a 23 August roll-out seem a little optimistic?

At any rate, this will just be a test roll-out. The first launch is not expected until the end of the year and this will depend very much on the outcome of the test firings of the first stage at the NIts RKP facilities in Peresvet. Those have been repeatedly delayed, the latest word being that they are scheduled to begin some time this month.

The race is on between Antares and Soyuz-2-1v to become the first rocket to fly with the NK-33 engine. Antares has a critical pad test firing of the first stage coming up at Wallops later this month or early next and if that goes as planned the first test flight could take place in October. Looks like this may become a tight race.

That's right. All the four N-1s that flew carried the NK-15 engines in the first stage. The fifth N-1 (vehicle 8L) *was* equipped with NK-33 engines, but never flew.

No, the Soyuz-2-1V has a payload capacity to low Earth orbit of only about 3 tons.

Progress currently uses the old Soyuz-U rocket and Soyuz the Soyuz-FG version. The intention is to eventually transfer both to the Soyuz-2-1A model, but that will take a while. It will take at least three Soyuz-2-1A launches with Progress vehicles to man-rate the rocket for Soyuz. Those flights are currently scheduled for late 2013, late 2014 and late 2015, so it won't be until 2016 at the earliest that both Progress and Soyuz will definitively make the switch to Soyuz-2-1A.

The A-frame is a part of the test stand IS-102. The actual launch facility is the same as for all other Soyuzes. The commonality is a part of the advantage of modifying Soyuz rather than putting an all-new launcher together. However, Soyuz-2.1v requires modifications to the Transporter-Erector. There was an enthusiast like Stan, who collected all serial numbers for all R-7 TEs. The early ones were quite different. Unfortunately, I do not recall where he kept the site.

It seems that the firing test in Peresvet failed. See the A. Zak website (http://www.russianspaceweb.com/soyuz1_lv.html#khsi2 (http://www.russianspaceweb.com/soyuz1_lv.html#khsi2).

Although, official Russian sources made no statements on the matter, sources in the industry said that the test had failed at the beginning of the firing and resulted in the damage to the hardware.

So, the October first launch could be delayed...

Tests of the rocket engine in Moscow area came to the end with failure
In the Research center of the space-rocket industry in the Moscow region there was a non-staff situation at fire tests of the rocket engine. About it reports "Interfax", banishing on a source in local administration.

«During fire bench tests received damage the engine of one of carrier rocket steps "Union". Victims aren't present. The stand is also damaged», – told to journalists a source.

He specified that the engine is made in Samara for the carrier rocket "Union".

«The commission which investigates circumstances of incident works at the enterprise and estimates a damage», – added a source.

Наибольший интерес вызвало выступление заместителя главного конструктора по науке НПО «Энергомаш» П. С. Лёвочкина. Он рассказал о перспективном двигателе РД-193, который предлагается установить на центральном блоке РН «Союз-2-1в» после того, как будет использован задел двигателей НК-33А. Работа по этому двигателю была начата в прошлом году. Сегодня создана трехмерная модель, завершается сборка двигателя-демонстратора.

Well duuuh, such a presentation would sure "evoke great interest" anywhere. I find it interesting indeed that Energomash "is finishing" the "assembly of pathfinder (RD-193) engine". They seem to be operating under assumption that they will install those engines to 2-1.v in 2020. Or they may be trying to create a fait accompli by actually working on the replacement for NK-33 while Kuznetsov do nothing to restart production.

Edit: Thanks to anik for the link.

Новая ракета-носителя легкого класса "Союз-2.1В" будет запущена в апреле 2013 года с космодрома "Плесецк

БЕРЛИН, 12 сентября. (АРМС-ТАСС). Новая ракета-носителя легкого класса "Союз-2.1В" будет запущена в апреле 2013 года с космодрома Плесецк. Об этом корр.АРМС-ТАСС на Международном авиационно-космическом салоне сообщил первый заместитель генерального конструктора самарского "ЦСКБ- Прогресс" Александр Сторож.

Разрешение на первый запуск новой ракеты-носителя будет получено только после того, как в Научно-исследовательском центре ракетно-космической промышленности (г. Пересвет) пройдут повторные огневые наземные испытания первой ступени ракеты, так называемый "прожиг" ракеты", пояснил представитель "ЦСКБ-Прогресс. В ходе испытания первой ступени ракеты на наземном стенде этого центра 16 августа произошла авария. Рулевой двигатель ступени перешел в нештатный режим работы, что привело к его разрушению, частичному повреждению первой ступени и кабельных систем, связывающих ступень с испытательным стендом. При этом к центральному двигателю НК-33 у специалистов никаких претензий не было. По данным экспертов, причиной аварии являются ошибки в работе системы аварийной защиты рулевого двигателя.

Таким образом, задержка первого запуска ракеты-носителя "Союз-2.1В" составит около четырех месяцев. Ранее представители предприятия после аварии сообщали, что первый запуск ракеты состоится в установленные сроки - в четвертом квартале 2012 г.

С помощью легкой двухступенчатой РН "Союз-2.1В" с Плесецка можно будет запускать на низкие круговые орбиты космические аппараты массой до 2,8 т. С использованием при пуске блока выведения "Волга" ракета обеспечит выведение на солнечно-синохронные орбиты космических аппаратов массой до 1,4 т.

Данная модификация ракеты-носителя "Союз" будет использовать унифицированные с остальными вариантами стартовый комплекс и систему управления. Вероятно, что именно данная РН будет взята за основу носителя "Союз-2-3". В случае успешных испытаний и введения в эксплуатацию "Союз-2.1В" будет конкурировать с такими носителями как российская "Ангара-1" и французская "Вега".

So NET April 2013 as official as it comes, although from TSKB and not Roskosmos. Obviously it's a guestimate on part Mr. Storozh that assumes that restarted fire tests conclude satisfactorily.

19.10.2012 / 14:29   В ОАО «НПО Энергомаш» проведено очередное огневое испытание ЖРД


      16 октября на научно-испытательном комплексе ОАО «НПО Энергомаш» без съёма со стенда проведено пятое огневое испытание экспериментального кислородно-керосинового ЖРД для первых ступеней ракет-носителей типа российской ракеты «Союз» и зарубежных ракет-носителей.
      Двигатель, оснащённый большим количеством дополнительных измерений вибро-напряжённого состояния, пульсации и температур, в ходе всех пяти испытаний отработал 678 секунд.
      Проведенным испытанием успешно завершён первый этап экспериментального подтверждения работоспособности новой модификации кислородно-керосинового ЖРД, создаваемого на основе технологий и опыта разработки двигателя РД191. Новый двигатель, имеющий тягу 200 тс у Земли, отличается от базовой конструкции введением ряда сварных соединений (камеры со статором турбины, смесительной головки газогенератора с корпусом), неподвижным креплением двигателя к ракете или через карданное соединение для качания целиком двигателя для управления вектором тяги в зависимости от конструкции ракеты.
      В отличие от РД191 новый двигатель короче по высоте на 760 мм и легче почти на 300 кг.
      Предполагается, что экспериментальный двигатель явится основой двигателя РД193 для I ступени ракеты «Союз-2.1в» лёгкого класса и других возможных модификации РН «Союз» и двигателя РД181 для I ступеней зарубежных ракет-носителей.
      Кроме того, на экспериментальном двигателе по программе, согласованной с ГНЦ ФГУП «Исследовательский центр имени М.В.Келдыша», решалась задача проверки работоспособности конструкции на режимах, соответствующих требованиям к системе МРКС (многоразовая ракетно-космическая система), разрабатываемой в рамках Федеральной космической программы.
      В настоящее время ведётся анализ результатов испытаний. Двигатель будет разобран и тщательно продефектирован. По результатам дефектации будет принято решение о возможности дальнейших испытаний и корректив в конструкторских и технологических решениях, передают пресс-службы Роскосмоса и ОАО «НПО Энергомаш».

Anatoly Zak also has that same info.
The RD-193 200tnf of sea level thrust, main differences with the RD-191 are on structural attachments. This would allow the engine to be used in a fixed form or with a thrust vectoring system.
Please note the RD-162 is a LOX/Methane engine, also of 200tnf, made by KBKhA Design Bureau. From what I've been reading, the reusable project is sort of currently competing the CH4 RD-162 vs the RP-1 RD-193. Let me show you some very interesting comparison with of the RD-162 with the RD-191:
RD-162RD-191Dif
SL Thrust (kN)20001920.84.12%
Dry Weight21002200-4.55%
T/W97899.08%
Chamber Pressure (kg/cm˛)175262.6-33%
Chamber Pressure (psi)2,4893,735
SL isp (s)3213113.22%
Vac isp (s)3563385.33%
And given the great advantages of CH4 for a reusable engine, as well as the lower chamber pressure, better T/W and isp, I do expect the Russians to go with the RD-162/CH4 combination.
On the Atlas V side, I see the Aerojet AJ-10000 as a very serious competitor. Specially since it would lower the foreign parts. And if Antares ever needs more engines, the AJ is also a natural. So I'm not sure about the RD-181 for the Atlas V.
On the other hand, the competition for the Ariane 6 does away with the nation-return rule. Obviously using a stock Angara would not be accepted. But if they used a Russian engine. Or even payed the royalty for an RD-181 and made it in Europe, that would be another thing. It could be slightly more powerful than the RD-180, and with the Vinci Ariane 6 might very well look a lot like an Atlas V with a bigger (albeit less efficient) upper stage.
Regarding the Soyuz-2-1v, I don't see them switching engines again without a good reason. They might use them for the boosters of an eventual Soyuz-3. But for now, I simply don't see them using it.

Apparently the YF-100 (which ends up as the 1st stage/booster engines of the CZ-5/6/7) is an enlarged, ground-start Chinese version of the RD-120 (which powers the Zenit's second stage). The relationship starts when the Chinese bought the RD-120 from Ukraine in the 1990s'......

(even the verniers, the RD-8, was re-engineered into a single chamber version, the YF-115, which will power the second stages of the CZ-6/7)

Was on the one Russian site and checked on the progress of the plans with Kuznetsov.   Looks to me that the plans to re establish production of the very large jet engines is under way.

Next should be restart of production of the former N-1 engines.  Not sure what they will be renamed.

NPO Energomash made a test of engine RD-191 on 16th october, according to NK. RD-191 could evolve into engine RD-193 for launcher Soyuz-2.1v, or to RD-181 engine for foreign use.
I think Energiya are trying to create a fait accompli for RD-193 while Kuznetsov is being absorbed into ODK and generally flounder. Eventually there will be no other path forward for Soyuz. That is why they throw their own money on RD-193 and report testing its "pathfinder" which is a modified RD-191 actually.

From a political perspective, it would make more sense for the Samara plant that makes Soyuz to use engines from the Samara Kuznetsov factory than to import engines from an Energia-controlled factory in Moscow.

For one thing, at any point, Energomash could decide that RD-180 production takes priority over RD-191/193, and the Soyuz 2.1V would be without engines (if they switched from NK-33).

Engine availability is the same problem Khrunichev is solving by the series production transfer. In other words, not insoluble. On the other hand NK-33 will run out eventually. You may be certain of that.

Traditionally, at for least first stage engines, they transfer the technology and serial manufacturing to the LV factory. This happens with Proton, Soyuz, Cyclone and Angara. Zenit appears to be an exception. But I'm sure that would the RD-193 be used for Soyuz, it would be made at Samara. Nobody commented on the fact that the RD-193 is 33% more powerful than the NK-33. Which, at the very least, would mean a reinforcement of the thrust paths.

Apparently the nk33-1 would have comparable performance to rd193, if they resumed production. I suppose that cost would be more important than performance and so decision on what engine to use would be based on that.

The r7 launch sites look over specified and should deal with the extra thrust?  I do wonder where all the extra fuel comes from to feed nk33 in soyuz 2-1.  The wider body gives so e greater capacity.  Will the burn time be shorter?

NK-33 has a deep throttling capability, which reduces prop consumption and increases burn time.

If you had 33% more thrust, you'd probably need to increase the tank's volume further to make it worthwhile. And I think the Soyuz-2.1v is sort of volume limited if you want to keep pad compatibility with the rest of the family. In any case, if you put an RD-191 and increase the tank's size, you end up with a pretty clear Angara competitor. I don't think the Russian can have the luxury of a dual and overlapping LV strategy (like the EELV).

Angara first stage engines are made at Omsk, Soyuz first stage engines are made at Samara. NPO Energomash might have designed both, but they only keep manufacturing for foreign markets (Zenit-2, Atlas V, and at least upto this KSLV). In any case, the Russian government is the one footing the bill. If they are willing to put their rubles, they might make two rockets with the exact same performance. I'm just saying that I don't see them doing that, and will probably try to keep the Angara and Soyuz-2/3 family with interleaving payload capabilities.
The whole point of the Soyuz-2 is to use the same pad, with minimal mods. I don't think they could still make it compatible if they needed much more volume. Let's remember that the RD-107 is in the 800kN class, the NK-33 in the 1,500kN, and the RD-193 in the 2,000kN. Of course that in  the single stick version the main propulsion would need to have more thrust since the RD-107 gives the stage a T/W of 0.84 (that's before you count the Blok I, fairing and payload).

Our member anik posted a link to the official website TsSKB Progress that deals with the rebuilding of the burnt test article:
 http://www.tsskb-progress.ru/novosti/vosstanovlenie-ustanovki-eu-763.html
In short:
 - Parts from the 2nd flight article were used to recover the fire test article (1st flight article is fully assembled and is in storage in Plesetsk waiting for the results of fire test -- zaitcev).
 - The fuel tank taken from the flight rocket had to be adopted for the test rocket by adding the test points, harnesses, and mounting hardware for installation on the stand (LOX tank was not damaged in the mishap; R-7 normally has no hold-down, needed on the stand -- zaitcev).
 - Fire test retake is slated for February 2013.

I would guess that one is the GRAU index number issued by the State, and the second is the factory number. 141KC would be the factory number, and 14S46 would be the GRAU index number, based on comparable systems.

My Russian is a little rusty, but my translation is roughly this:

They performed the next test of the engine, this time with added systems for protection from off-nominal situations.

The goal was to test the reliability of the protection system of the rocket engine.
During the test of the NK-33A engine after reaching the maximum values of the off-nominal shutdown sensor, the control function of the engine worked on time. The engine was shutdown at the necessary moment.

The check of the engine protection systems will be continued. The next test is planned soon.

This is the third acceptance testing engine NK-33A in the year. As you know, the engine is designed for the planned flight tests as part of the launch rocket "Soyuz-2-1v." The tests were on the planned scheme, the NK-33A has once again demonstrated the reliability of key characteristics. Immediately after the fire test, this engine was sent to the assembly plant for the production of the final preparations for the handover.

A source writing on the "Globalnaya Avantyura" forum reports that the second attempted test firing of a Soyuz-2-1v first stage at the facilities of NITs RKP in Peresvet today ended with the stage shutting down 50 seconds ahead of schedule. The problem reportedly was not with the NK-33A main engine, but with the RD-110R steering engine. This is just preliminary information, no official confirmation yet.

http://www.avanturist.org/forum/topic/101/offset/6900/

During the first test firing on 16 August last year the stage shut down less than 10 seconds into a scheduled 200 second test firing. The tail section was damaged in the incident, forcing the stage to be shipped back to TsSKB/Progress in Samara for repairs.

A contributor to the "Novosti kosmonavtiki" forum writes that the stage did shut down about 50 seconds earlier than planned (150 seconds into a scheduled 202 second burn) due to a leak in one of the propellant lines leading to the RD-110R steering engine. However, because this is a test stand version of the engine some of the connections in the propellant lines are not standard (using bolts rather than welds) and therefore the test is still considered a success.

The fun part is the swapout of the rocket.

So, it will be sent to the launch site, and unit #1 returned to factory for modifications. In the end we have, oh, about 1 year of delay.

The first launch now planned in November-December ...

http://ria.ru/science/20130828/959050580.html (http://ria.ru/science/20130828/959050580.html) (On Russian)

The fun part is the swapout of the rocket. The flight unit #1, which was delivered to Plesetsk in anticipation of successful test of Unit 376, is going to be replaced by the flight unit #2, which was at the factory during the saga of tests and thus received the necessary modifications. So, it will be sent to the launch site, and unit #1 returned to factory for modifications. In the end we have, oh, about 1 year of delay.

thx for the update, maybe this will turn into a good thing and you can launch another unit quickly after.

Soyuz-2.1v test launch put off until year's end - source


The first test launch of a Soyuz-2.1v light-class carrier rocket from the Plesetsk cosmodrome has been put off from the first part of October until the end of the year, a source at the cosmodrome told Interfax-AVN.

"The launch has been postponed until nearer to the end of the year," he said.

The carrier rocket is to be launched with a Volga second stage, two SKRL-756 calibration spheres and an Aist 1 satellite.

The first launch was initially set for the beginning of 2012, but was put off over an accident during land hot testing of the first stage.

Reports said earlier that the launch could be carried out on October 10

Is the first flight still on track for launch next month?

I am now betting one 3 month L2 subscription that the F9 v1.1 will fly before this one. Anyone following?  ::)

Well Andrey's launch schedule now just shows that the maiden flight of this is now scheduled on December 24 (did the Russians signed a deal with Santa?  ;)). That means another potential Antares launch before it flies......  ::)

I'm not sure to what the "original R-7 top stage" refers. Original R-7 had 2 stages, with 2nd stage being in the center, not on top, due to its cluster design. But to the best of my knowledge, Volga is a derivative of Kobalt's equipment bay in the same way Ikar was, only it's redone to be smaller. It retains the characteristic truncated cone shape and general layout of engine, tanks, etc.

Putting translation aside:
unless it is referring to a later iteration of R-7 which if i understand properly it might be referring to the propulsive manuvering stage used to make final corrections to the warhead. I might be wrong, but I think that is correct.

No.

Volga is a lighter version of the venerable Ikar stage, which was used on some earlier Soyuz flights as an orbital maneuver stage (for Globalstar launches), but which is normally used as the service module for certain Russian military spacecraft. Ikar is basically the Samara knockoff of the Soyuz PAO, with many analogous components, and with very similar mass properties. Volga's dry mass is about 1/2 that of Ikar, but it has a similar propellant load.

I believe that some Russian military spacecraft will use the Volga bus instead of the Ikar bus.

That is not unusual for LEO-maneuvering pressure fed propulsion modules of this type, which don't need to provide substantial delta-v but which do need to serve multiple purposes while being rock solid reliable.  Cygnus and the HTV and ATV service modules, for example, probably have broadly similar, even worse, mass ratio properties.  Volga also seems to serve a dual purpose as a payload adapter, which would add dry mass.

There was also the first stage test article, which was destroyed during a firing on 16 August 2012 2013. The first test firing of a heritage NK-33 for Aerojet was on a test stand at Stennis in 1995.

5 years from the date of the first launch of the Soyuz-2 light class LV of stage 1c
December 28, 2018

December 28, 2018 marks 5 years since the day of the first successful launch of the launch vehicle of the light class "Soyuz-2" of stage 1c, developed and manufactured by Progressing RC.

The two-stage Soyuz-2 launcher of stage 1c is designed for launching spacecraft weighing up to 3 tons to a low near-earth orbit, and using the upper stage Volga to 1.4 tons - to a sun-synchronous orbit. This is the first light-class booster using liquid rocket engines, developed in modern Russia.

The launch vehicle Soyuz-2 of stage 1c was developed with maximum use of structural elements, on-board systems, production and technological base, and unified technical and launch complexes available for a Soyuz-2 type launch vehicle. This has significantly reduced the cost of developing, operating and launching the launch vehicle.

The booster is designed in a tandem pattern. The NK-33A engine (produced by PJSC Kuznetsov) and the RD0110R steering engine (developed by KBKHA and manufactured by the Voronezh Mechanical Plant) are installed on the central unit. To ensure the stability, controllability and operation of the Soyuz-2 control systems of stage 1c, a control system with a Soyuz-2 LV of stage 1b is used with the development of software and mathematical software and a change in instrumentation.

To provide an energetically optimal scheme for launching payloads to medium circular orbits, as well as to sun-synchronous orbits in conjunction with the Soyuz-2 stage of stage 1c, the Volga launch unit developed and manufactured by RCC Progress is used.

According to the results of the first launches as part of the flight design tests, a number of modifications were made to the Soyuz-2 launch vehicle of stage 1c. In particular, the volume of experimental measurements (pressure, temperature, vibration) on the blocks I, II of the LV and BV Volga was increased.

The flight test program provides for 5 launch campaigns. At the end of 2018, there were 4 launches of this media.

If they are able to return the money to Areojet for the engines earmarked originally Antares.  There is couple more engines. The plan is to exhaust the engine supply and switch to RD-191/RD-181 that's used for Angara & Antares now. Now the trade off between Angara 1.2 and Soyuez 2-1v. One has more pads then the other and is flying now.

Engines converted to AJ-26 have modifications that would not be economical to reverse and convert to the version used on Soyuz-2.1v. Instead RD-193 Will take over as the booster engine as well as a new steering engine assembly that is optimized for the booster stage. If Soyuz-2 series lifespan is extended the plan is to resume the upgrade of the strap on boosters to provide greater medium lift capabilities in the interim period. Soyuz-2.1A and B sub families variants would be retired and replaced by the interim version. Further commonality would reduce costs and other factors.

The service life of the engines for Soyuz-2.1v launch vehicles will be extended by seven years.

Moscow. 21 December. INTERFAX.RU - The life of the engines for Soyuz-2.1v launch vehicles is planned to be extended by seven years, follows from the materials of the public procurement portal.

"The purpose of the work is the extension for 7 years of the warranty period for the 14D15 engines manufactured from the material part of the 11D111 (NK-33) engines manufactured in 1972-1974 for use as part of the PH 14A15," the tender documentation posted on portal.

Works must be completed before May 31, 2019. They are held in the framework of the experimental design work "Rus".

Earlier it was reported that a new engine, the RD-193, was developed for the Soyuz-2.1v, which will have to replace the NK-33 engines after they are exhausted.

The NK-33 are now about 45 years old.
Would that be the maximum warranty of the engines achieved?

The RD-170, RD-180, RD-19x use the same basic engine design, right?
This was developed for th Buran Shuttle.(?)
The Soyuz-5 is planned to use a RD-170 derived engine, right? That's the long term successor of the Soyuz(-2).
Wasn't there back in early 2000s a Soyuz 2.3 proposal? Are they reproposing that?

And is my understanding correct, that the difference between the RD-191 and RD-193 are:
- a slightly lower thrust level (lower  pressures)
- RD-191 is vectorable, RD-193 is fixed mounted.
Thus the second gen Soyuz 2.1v requires vector engines, where Angara-1.2 doesn't.

AFAIK, the RD-1X0 family of oxygen rich staged combustion RP-1/LOx engines have a very good track record. In my opinion the hypergolic propellant first stages can't be phased out soon enough. (Proton, Rockot, Dnepr)
I highly welcome the Angara family and Soyuz 2.1v, Soyuz 2(.3) and Soyuz 5.
I think many small launcher start-ups and launcher competitors have benefited a lot from the slow introduction of the Soyuz 2.1v. It's a nice small(ish) launcher.

Edit to add: didn't the Soyuz 2.1v required  some pad modifications !?
Only one launchpad at Plejetsk has been modified. Thus for pad availability Soyuz 2.1v doesn't have an advantage over Angara 1.2.

Only one launchpad at Plejetsk has been modified. Thus for pad availability Soyuz 2.1v doesn't have an advantage over Angara 1.2.
They are from the same line but do have moderate differences in their adaptation from 4 thrust chambers to 1 or 2 chambers.

As for Soyuz-2 16/2 is closing in on completing its conversion to solely launch Soyuz-2.1v and if higher demand comes forth 41/1 is other pad to be rebuilt for dedicated launches. 43/3 and 43/4 are configured to launch all versions whereas 16/2 and 41/1 would solely support light launches. 43/3 is to resume launches this year.

As for Angara, the Complexes were designed from the beginning as double pads due to Zenit heritage, but only the left pads are being built first and the right pads are deferred indefinitely for budgetary and economic constraints.
Russian Angara and Soyuz-2 launch complexes
Soyuz pads:
41/1: Previously dismantled to repair other pads and accident. Would be rebuilt for all Soyuz-2 versions BUT dedicated to launch only Soyuz-2.1v version.
16/2: All Soyuz-2 versions BUT dedicated to launch only Soyuz-2.1v version.
43/3: All Soyuz-2 versions
43/4: All Soyuz-2 versions
1/5: to be converted for Soyuz-2.1A and B with upper stages however capable of being upgraded for Soyuz-2.1v.
31/6: All Soyuz-2 versions BUT requires modification and installation of Soyuz-2.1v specific hardware.
1S (fka 1S/7 and later 1S/1 (left pad)): designed for all Soyuz-2 versions BUT requires installation of Soyuz-2.1v specific hardware.
1S (fka 1S/8 and later 1S/2 (right pad)): designed for all Soyuz-2 versions BUT deferred idefinitely

Angara (Zenit) pads:
35/1: operational and undergoing additional installations
35/2: Deferred indefinitely for budgetary and economic constraints.
45/1: Active Zenit and now planned for Irtysh launcher. Proposed during early Angara development for conversion (Consideration since cancelled).
45/2: Destroyed in Launch Failure. Proposed during early Angara development for conversion (Consideration since cancelled).
1A (1A/1): Under Construction with development troubles.
1A (1A/2): Deferred indefinitely for budgetary and economic constraints.

Does any one know; how many NK-33 engines, suitable for Soyuz 2.1v, Russia has on stock?

The Russian company S7 Space, which owns Sea Launch, plans to resume production of the NK-33 and NK-43 rocket engines to create a returnable Soyuz-5SL rocket. This was stated by the Vedomosti newspaper, owned by the family of Demyan Kudryavtsev , by the general director of a private company, Sergei Sopov .

“We would like to buy from the state the world-famous NK-33 and NK-43 engines, which were previously produced by the Samara Kuznetsov plant , as well as documentation, equipment, and technical reserve. In general, all that survived on this topic from the Soviet program. We intend to restore production, build our own rocket engine plant in Samara, ”said the businessman.

According to him, the construction of the plant and the restoration of production will take 5-6 years. Up to this point, it is planned to use the 36 NK-33 and NK-43 engines stored in storage. “This allows us to start a flight test program for the Soyuz-5SL rocket, without waiting for the launch of mass production of the upgraded NK-33 and NK-43,” said Sopov.

I do not think that it comes to use NK-33/43 at Sea-Launch.

Some NK-33 are still there. So they could still be used in the Soyuz 2.1v.
One pad (or more) is available in Plesetsk, but are the rockets actually being built?
Are currently ordered which?

For the Angara 1.2 is also a pad in Plesetsk ready, but there is no rocket.
The right Angara 1.2 had no launch yet.
I have not read, whether the smaller 2nd stage for the 1.2 is now ready.
The Service-Module had a test fire last year, i think.

NK-33A for the military until 2023.

About 10 engines can still be used or assembled from individual parts of several NK-33 and NK-43 engines.
