74 seconds hot fire test - Helix engine

RFA successfully hot fires Helix engine for a total of 74 seconds
74 seconds! This is the total time we have now hotfired our Helix in flight configuration. The test campaign consisted of three tests of 4, 30 and 40 seconds each - without the need to replace any components on the engine. A great achievement which once again illustrates how reliable and performant Helix is.

Das sind tolle Neuigkeiten und wahnsinnig schöne Daten. Vielen lieben Dank für das Video und viel Glück und Erfolg bei den nächsten Schritten

Sehr cool, dass ein fortgeschrittenes Triebwerk aus DE kommt! In welches Startsystem wird "Helix" integriert, Smallsat-Launcher oder doch eine Mittelklasse-Rakete? Und warum habt ihr euch für einen so komplexen Verbrennungszyklus entschieden?

Can’t wait!

[@TULDSkySaac]

Very nice!

[@jeffcampbel]

Congratulations!

Espero estar comentando aqui sobre um registro histórico do Primeiro passo para o sucesso de uma das grandes fábricas de foguetes do futuro! Muito animado

How do oxidizer-rich engine cycle engines compare in cost to other engine types? The super alloys needed to keep the pumps from melting are not cheap.

Right or the science to make this

[@howbigisyourlove]

where do you do your fire testing .. right now our community in Canada is having issues with Spaceryde testing on rural property near homes and farms .. just wondering if you do your testing remotely by comparison .

Congratulations to the whole team! What an achievement!

[@nemesiocanillas3298]

Just a question. What is the engine cycle type and the name of this engine? Just curious.

[@rfa_space]

Our "Helix" is a oxidizer-rich staged combustion cycle engine

[@oliwierkwiatkowski8817]

@@rfa_space What about thrust and ISP of the engine?

[@nemesiocanillas3298]

@@oliwierkwiatkowski8817 this is a kerolox engine, closed cycle so I'm assuming its ISP is higher than that of SpaceX's Merlin 1d. For thrust I think it's slightly less powerful which I'm assuming the rocket stage itself has the same engine layout as Falcon 9 and kinda same tonnage of payloads. IDK just a thought.

74 seconds will not get a rocket into space..

Literally not the point of this exercise
