According to the web site, they are using 9 engines in the first stage, and 1 in the second stage.

I have no idea what Ukrainian engine this is based on.

There it is written 1600 kg into the ISS orbit!
The numbers are close to the Rokot. But the Rokot developed 190 tons of thrust at takeoff.
RFA One less than half.  ???

That's what ISP does for you. If you took a Rokot/Briz-KM and replaced the 290s/322s/326s storable engines with +50s ISP because of Methane, payload rises from 1800kg to 3700kg.
Which booster has the most soot? SpaceX booster launch history! (discussion)

Interesting race between Rocket Factory Augsburg and Isar Aerospace in Germany. Isar seem to be better at raising money, but very young / inexperienced in actually building things. Has anybody seen an engine from them yet?

Rocket Factory Augsburg (terrible name) seem to have less money, but they are joined at the hip to OHB and MT Aerospace, and they seem to know how to build things quickly (or buy them in from experienced, relatively cheap partners like Yuzhnoye). They also seem able to piggyback on SpaceX PR to build their brand.

If you had just given $180,000,000 to the young students at Isar Aerospace you might be wondering if you had backed the wrong horse. It's a little embrassing for a company with that much backing that a competitor founded in the same timeframe and without those hundreds of millions is already able to show engine tests and large structures...

Maybe they should merge? Together they might be more effective.

Youtube link to RFA webanir which had few German aerospace industry people on it.

https://twitter.com/rfa_space/status/1437413370429333513?s=19

Mainly about RFA hyping on about their highly efficient stage combustion engine and how it makes for better LV. While great engineering feat doesn't necessarily make for low cost launch.

Woman that is launch services provider basically said they don't care about engine, just has to be low cost and reliable LV. Did have some interesting comments regarding what satellites customers want. Prove of concept tech demos, a cheap ride to space don't a care about orbit. When comes to constellation deployment, accurate orbit insertion becomes more important along with launch on demand and they are willing to pay more for it.

Rocket Factory Augsburg has signed two more launch contracts (bolds mine):

Rocket Factory Augsburg lands new customer in build up to first launch [dated Nov. 18]

Quote
German launch startup Rocket Factory Augsburg has signed a new customer for the first launch of its RFA One rocket next year.

The firm announced Nov. 18 a launch contract inked at the Space Tech Expo Europe in Bremen with Ukraine-based Lunar Research Service (LRS) for launch of a research mission.

The spacecraft will launch on the first flight of the reusable RFA One launcher, currently set to take place at the end of 2022 from Andøya spaceport, Norway.

During the expo RFA also signed a memorandum of understanding for cooperation with Morpheus Space with a view to integrating Morpheus propulsion systems in the RFA One, as well as another MoU with London-based space tech startup Lúnasa relating to the latter’s reusable orbital transfer vehicle named VIA.

Plus Ultra aims to provide communications infrastructure for incoming wave of moon missions [dated Nov. 19]

Quote
Spanish-German company Plus Ultra Space Outposts is making moves to be the provider for essential communications and navigation infrastructure for upcoming moon missions.

The Spanish-German company signed a launch agreement late October with Germany startup Rocket Factory Augsburg to launch Plus Ultra’s first satellite.

That mission, set to launch in the final quarter of 2023, would see the roughly 400-kilogram satellite sent into geosynchronous transfer orbit. The satellite will then use its own electric propulsion system to reach lunar orbit, arriving in place around six months later.

<snip>

Plus Ultra’s Harmony constellation aims to provide greater coverage and data rates than those set out in requirements such as those in NASA’s LunaNet initiative, which seeks to put infrastructure in place, possibly using public-private partnerships, service contract arrangements and potentially multiple providers.

“We’re talking about 100 megabits per user, we’re talking about global coverage, we are talking about a GPS-like navigation system,” says Ströhl. The goal would be to change communications and navigation from a carefully managed resource into an on-demand service that enables new capabilities.

The completed constellation would consist of eight satellites orbiting in two planes, at 6,000 kilometers above the lunar surface and using laser communications links. The first four satellites would already provide 80% coverage of the lunar surface. The completed constellation would provide 100% coverage.

That Plus Ultra contract was actually announced during IAC 2021 at the end of October, same as the SENER contract. Another contract from then is with Neutron Star Systems, who plan to fly a demonstrator for their electric propulsion system.

Stefan Tweraser is new CEO of Rocket Factory Augsburg since October. Zero aerospace experience. He worked as sales and product manager for some Internet companies, including Google Deutschland. Studied telecom engineering, business administration and psychotherapy.

Quote from: Stefan Tweraser
There are enough ideas and technological knowledge at RFA, nearly too much. E.g. there are ideas in the company to build larger rockets, to enable transporting larger satellites. But this just distracts from the actual goal.

I want to sharpen RFA's product focus. Despite of all creativity and passion we face the exciting challenge to build a low-priced rocket with high reliability.

Of course Hortense is talking about how Isar is clearly a fraud in the RFA thread. Of their 11 posts, 10 of them have been "Isar is a fraud." We get it, you're not a fan. If Isar were publicly-traded, I'd assume you've put your life savings into shorting them.

RFA and Southern Launch sign agreement for launch facilities

Singapore, 10. February 2022 – Rocket Factory Augsburg AG (RFA), Europe’s leading launch service provider, has partnered with Southern Launch, a South Australian rocket launch facility provider. The partnership allows for the German launcher RFA ONE to be launched from Southern Launch’s Whalers Way Orbital Launch Complex in South Australia. Southern Launch’s orbital complex provides direct ascent into sun-synchronous and polar orbits.

The agreement will enable RFA to provide flexible, low-cost, and precise launch services with its RFA ONE from a regional spaceport in the Asia-Pacific region. This three-stage small rocket, with its highly efficient staged combustion engine and orbital stage, can deliver up to 1,350 kg to a 300-km polar orbit. The rocket is 30 meters high and 2 meters wide and has reached important milestones in its development over the past year. The RFA ONE is expected to launch up to fifty times a year in the future, delivering satellites into near-Earth orbit quickly and reliably at a highly competitive price point

The first engagement between RFA and Southern Launch was at the International Astronautical Congress, Washington in 2019, and the parties are now very pleased to have finalized and to be signing a launch services agreement at the Global Space and Technology Convention in Singapore.

Jörn Spurmann, Chief Commercial Officer at RFA, says: “Launching from South Australia allows us to offer our launch services in a highly customer-oriented way from a regional spaceport in the Asia-Pacific region. It marks a central milestone in our strategy for a globally distributed launch capability. With various launch sites around the world, we minimize our customers’ logistics and time constraints and lay the infrastructural foundation for a weekly launch cadence. Southern Launch offers a comprehensive and competitive service to launch our rockets. We could not have wished for a better partner.”

Lloyd Damp, Chief Executive Officer of Southern Launch, said: “We are excited to announce this partnership with Rocket Factory Augsburg AG, which will see their launcher RFA ONE launched into space from Southern Launch’s sites in South Australia. This partnership further demonstrates Australia’s world-class space launch capabilities to the international space industry.”

With sufficient thrust, pigs fly just fine - however, this is not necessarily a good idea. It is hard to be sure where they are
going to land, and it could be dangerous sitting under them as they fly overhead.

Enough with the renders! Let us introduce: The #Helix engine 🔥

Ready for some more information on this marvellous piece of #engineering and the chance to win unique polaroid pics of this beauty? ⬇️ (1/6)



Our #Helix is the first staged-combustion engine in the EU. Its oxygen-rich closed-cycle allows it to run more efficiently and be more #performant than open cycle engines. It is made of ❓ different materials, all working together to produce 100kN of thrust. (2/6)



On our 1st stage we have 9x Helix with an Isp of 325s, on our 2nd stage one vacuum optimized Helix with 350s. Being closed-cycle, it emits fewer sooty exhaust gases, making it more #environmentally friendly & compliant with our vision to get closer to Earth from space. (3/6)



Critical parts of the engine are #3Dprinted, which is perfect for complex and very fine structures, e.g. cooling channels. 3D printing also allows us to significantly reduce costs & production time as well as scaling and #automation of the production. (4/6)



Last July, we successfully tested our in-house developed #Helix engine for the first time. Now that the first engine in flight configuration is ready, we are preparing for a long duration hot fire test. Stay tuned on that, it's going to be spectacular! (5/6)



Now for the question mark from above: Can you guess how many different materials are used in the #Helix? Comment your guess to enter a draw for a chance to win one of only a few unique polaroid pictures of this beauty 😍 (6/6).

RFA posted a follow up image with major components of their engine labeled:



Looks like they're using electric TVC actuators. I'm aware technological capability here as improved over the last 10 years, but it seems like an odd choice for given the fuel pressures they're likely working with in a staged combustion engine (with their performance, I'm assuming they're using kerosene, but couldn't find explicit reference to it).

They're using the tried-and-true TEA-TEB system with a canister/ampule made from what appears to be welded pipe caps.

It's interesting to see a spin-start exhaust. I haven't paid too much attention to staged combustion engines - I assumed that would exhaust through the normal turbine exhaust path like it does on gas generators but I guess that could have detrimental impacts to start up operations/transients.

RFA has won the second round of the German Aerospace Center (DLR)'s microlauncher competition. This contract is worth 11 million Euros, and DLR will put payloads of up to 150kg on each of RFA's first two launches.

You may recall that Isar Aerospace won the first round of the competition, with an identical prize (11 million Euros to carry 150kg on their first two launches). That just leaves HyImpulse, the third competitor, without a prize as of yet.
