report to the community that the final name for the rocket eninge will be HELIX with rocket engine test image in the background

Augsburg, Germany, March 10, 2022 – The staged combustion engine of Rocket Factory Augsburg (RFA) is given the name “Helix”. This name was suggested by two fans from the USA as part of RFA´s #NameOurEngine campaign. Over 3,800 names were submitted, from which RFA selected its TOP 10 and put it to two public votes. “Helix” emerged as the winner of the final round with “Tycho”, “Fernweh” and “Daedalus”. A total of over 17,000 votes from all around the world were cast in both rounds.


This makes RFA the first company in the world to have its engine named by the public. The submitters were also able to provide a reason. In the case of Helix, the reason is that DNA has the shape of a helix. The DNA of the rocket is its engine, the entire rocket depends on it. It is what breathes life into the machine. Moreover, this gives new meaning to the phrase “Space is for everyone” because everyone is made of DNA.

About the Helix engine

Helix is a staged combustion engine, one of the most advanced engine types in the world. Unlike engines with an open combustion cycle, in RFA´s Helix engine the exhaust gases from an oxygen-rich preburner are fed into the main combustion chamber after driving the turbopump. The fuel is thus burned more completely, increasing Helix´s efficiency by 7%, which translates into 30% more payload capacity of the RFA ONE micro launcher. Staged combustion is also more environmentally friendly, as significantly fewer highly sooty exhaust gases are released into the atmosphere.

The Helix engine is operated with RP-1 as propellant and liquid oxygen as oxidizer, has a thrust of 100kN and an Isp of 325s (SL) / 350s (Vac). Nine Helix engines are used in the first stage, and one vacuum-optimized Helix engine in the second stage.

Dr. Stefan Tweraser, Chief Executive Officer of RFA, said: “We were overwhelmed by the many great submissions and appreciative feedback. Many people have really put a lot of thought and love into creative, beautiful, unusual and profound names and reasons. Helix is a beautiful name with a fitting meaning. We are proud to say that our Helix engine has been named by the public and will continue on this path of participation and open communication. “Space is for everyone” is not a phrase for us, we are tackling this adventure together as humanity”.
