Remind me to pass this on to Orbital guys.

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.
I am sure that they are aware of the NK-33 Curse.
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?
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.
You're quite right. What then, may I ask, is the NK-33 curse?
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.
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, A3AFAIK 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.
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.
It is interesting that the configuration of Soyuz-1 is not defined till now definitively. For comparison:
http://www.samspace.ru/RN/souz_1.htm
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.
I'll admit, this launcher is starting to impress me. I could easily see this being the main crew launcher for a long time.
It depends on the configuration. IIRC, there was a configuration which retained the four boosters, which was more than sufficient for crew launch.I'll admit, this launcher is starting to impress me. I could easily see this being the main crew launcher for a long time.
Isn't this LV supposed to be less than 3mT to LEO?
Is that really sufficient for a crew launcher?
If I recall correctly, Soyuz-2.3 was cancelled long ago. That said, if Soyuz-1 is successful then there could be an argument to resurrecting the programme.That dovetails with what I've heard that they are waiting to see if Soyuz-1 is a success, and if it is then they will look at Soyuz 2-3.

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.If I recall correctly, Soyuz-2.3 was cancelled long ago.

According Anatoly Zak's website (http://www.russianspaceweb.com/soyuz2_3_lv.html), Soyuz 2-3 payload capacity will be less than 13 tons to 200km, and that's from Korou. It becomes closer to 11 tons when launched from Baikonur or Plesetsk.
Given that capacity, what payloads would it launch?

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.
About GLONASS, according to insiders posting to NK forums (Mr. Morin), the Chief Designer Mr. Kirillin plans to put upper stage Volga on the 1v. This explains how he plans to launch GLONASS, I think, although I did not look closely at Volga.
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.

No, it is not. Ikar used 17D61 "Kometa"("Yantar-1KFT") KDU.
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.
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.
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.It has a different mass, engines, shape and size.

Volga is Ikar without pressurised volume.
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).http://www.svengrahn.pp.se/histind/Recces/fourth.htm
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).
Any updates for first launch? I am eager to see this liftoff.

Flight tests of the carrier rocket Soyuz-1 "will begin this year - HFand
24/03/2011 00:27
MOSCOW, March 24 - RIA Novosti. Space Force (EF) of Russia are planning this year to begin flight tests of rocket easy class Soyuz-1 ", reported on Thursday by the official representative of the Russian Space Forces Alexei Zolotukhin.
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 ".
Aleksei Zolotukhin, reconfirmed that Soyuz-1 would fly in 2011. Unofficial reports at the time said that during its first test launch, scheduled at the end of the year, the vehicle would carry the Aist small satellite developed at TsSKB Progress.
Head of Federal Space Agency, told reporters that the first test launch of a new Russian carrier rocket light class "Soyuz-1" will be performed from the Plesetsk cosmodrome in the first half of 2012
According to him, there are two reasons for the delay the first launch of "Soyuz-1", originally scheduled for this year.
"Firstly, it is necessary to conduct test firing missiles. Second, is not ready payload - a satellite" Lomonosov "Moscow State University," - said Popovkin.
"The term of his readiness - April 2012", - he said.
15 and 26 October at the ground test facility "Vintay" successfully tested a rocket engine NK-33A. Regular tests took place with the "reverse faults" of the particles in the feed line to the oxidizer and the fuel supply line, thus confirming the requirements of technical specifications for the engine. In both cases, the engine worked for 220 sec.
In the near future one last test with the engine working off mode in the final stage of the input conditions. After the final stage starts the engine on the test results will be prepared by the conclusion of his admission to the Interagency Testing.
12/13/2011
Launch vehicle "Soyuz-2-1v" arrived at the fire tests
December 13, 2011 in the assembly and testing facility of IP-102 PCF "SIC RCP" Peresvet city unloaded blocks 2A and 1A (tank of kerosene with the engine compartment and a tank of oxygen) of the first stage "Soyuz 2-1v" launch vehicle.
After docking of the loop blocks and work on the part of the input controls the first stage booster rocket "Soyuz 2-1v" will be removed from the MIC and is set to stand trial for two cold and fire test bench.
Conduct cold (HSI) and fire (OSI) test bench in 2012. According to the results of DCI and the HSI will be determined by the readiness of the launch vehicle for flight tests.
Joint press release of the PCF, "SIC RCP" and "TsSKB-Progress"
No, it is not. Ikar used 17D61 "Kometa"("Yantar-1KFT") KDU.
There is the Orlets-2 (Enisey) KDU.No, it is not. Ikar used 17D61 "Kometa"("Yantar-1KFT") KDU.Sorry to go a little off-topic, what is the 17D62 engine?

I was told that the launcher will be tested in Plesetsk next week, and that the rollout to launch pad n°4 (17П32-4) will be on 23rd august.
That's three days sooner than the reports I was reading. I hope it is true.I was told that the launcher will be tested in Plesetsk next week, and that the rollout to launch pad n°4 (17П32-4) will be on 23rd august.
I believe that this is the first ever actual scheduled launch date for an NK-33 powered launcher, after some 40 years or trying.

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.
Is this the new strongback (not sure what the russian term is for it). Like the ones used in the N-1 & Buran programs?

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.
It seems that the firing test in Peresvet failed. See the A.

So, the October first launch could be delayed...
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.
Kuznetsov needs cash to start gas turbine production for Jets, then NK-33 right?
Kuznetsov is part of the Soyuz group now correct?
Kuznetsov is a design bureau, not a production unit.

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».

what Chinese system is using Energomash technology?
??? ??? ??? ??? ???
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.

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.
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).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?

how can Soyuz compete with Angara if the Angara cometitor makes the engines for your LV?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.

Nice picture of Volga upper stage:
http://www.samspace.ru/multimedia/images/selected_images/105/
I've been told that upper stage Volga has designation 14S46 (14С46).
Any updates on this? Been close to a month.Last I that I'm aware of was second attempt at end of February to nominally complete stage one static hot fire test with first test launch in April 2013 per Anatoly Zak's website.
According to the NK forum (http://novosti-kosmonavtiki.ru/forum/forum14/topic12755/) it uses both designations:I've been told that upper stage Volga has designation 14S46 (14С46).
And another information : TsSKB-Progress's internal designation for Volga was 141KS (141KC).

The launch date for the first S-2-1v will be decided by May: http://novosti-kosmonavtiki.ru/news/7639/ (http://novosti-kosmonavtiki.ru/news/7639/)
In Podmoskov'e have successfully completed the first test firing unit carrier rocket light class "Soyuz-2-1v", produced in the Samara Space Center rocket "Progress Samara Space Center." This was reported today by the press service of the Samara engine-enterprise "Kuznetsov".
The tests were conducted on the basis of Research and Testing Center aerospace industry in Relight the Moscow region. The purpose of the test firing was to develop the propulsion system in the block of the first stage, including cruise missile engine NK-33A development and production of "Smiths".
"The engine operated in accordance with the standard patterns, and the logic operation of all systems of the rocket block, confirming its reliability. Past fire tests - is another major step towards the flight test rocket" Soyuz-2-1v ", - the press-service of the the enterprise.
First launch now planned in September: http://ria.ru/science/20130608/942207144.html (http://ria.ru/science/20130608/942207144.html)
Is he saying that a they will also launch a military kosmos satellite on 2.1v?
first half of October – two calibration spheres SKRL-756, Aist No. 1 – Soyuz-2-1V/Volga – Plesetsk 43/4
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? ::)

You bet something you know you're never going to lose. Big deal ;D
I just hope and pray that it doesn't destroy the only operational R-7 pad at Plesetsk.

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.

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...... ::)Russia is mostly Orthodox country, and as such, Christmas is celebrated on Jan 7, But the main holiday there is New Year's day.

It seems that there are rumors on NK that the first launch can happen by the end of THIS MONTH! (http://novosti-kosmonavtiki.ru/forum/forum12/topic13493/?PAGEN_1=4) :o
(with Meridian 7 in December)
Any updates about the payloads and the rocket? What is left to do before the initial launch attempt?
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:
Is the Volga a redo of the original R-7 top stage?
I have information according to which Volga upper stage has a propulsion module called 14Д520.
14Д520 consists of :
- Main engine 17Д64 (КТД - корректирующе-тормозной двигатель)
- Correction engines С5.142 (ЖРДМТ - жидкостных рулевых двигателей малой тяги). There is 16 engines of this type, dispatched in two groups of eight engines.

Is the Volga a redo of the original R-7 top stage?
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.
First thing I found was from anatoly zak: http://www.russianspaceweb.com/volga.htmlThat 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.
very bad dry to wet mass ratio.

This is to remind everyone that there is another launcher besides Antares that uses NK-33.AND to also remind everyone that the joint American/Russian Project has lost more than a few engines during testing which resumed in 1994. There was also the first stage test article, which was destroyed during a firing on 16 August 2012
as well as a first stage test article during a firing in 2013 (year ?).

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.
In 2019, the final test flight is planned.
What happens next? Are further launches planned?
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.If they are able to return the money to Areojet for the engines earmarked originally Antares. There is couple more engines.

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.
https://www.interfax.ru/russia/643402AFAIU: The warranty lapsed not to long after the N-1 and associated programmes were terminated. The warranties resumed in the early 90's and have been maintained since then.

The NK-33 are now about 45 years old.

They are from the same line but do have moderate differences in their adaptation from 4 thrust chambers to 1 or 2 chambers.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.

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.
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.
