THERE'S STILL A FEW THINGS TO DO
The intake, combustion and exhaust stage of a Fenris rocket engine contains ZERO moving parts. Debris (up to a reasonable size) just acts as free reaction mass. Constructed of ultra-durable super-alloys, a Fenris engine is built to last, on any planet, in any fluid, liquid or gas.
FREE REACTION MASS?
Ever wonder why rockets aren't incredibly efficient and using all of the air around them for the bulk of their reaction mass? Yeah we did too. Then we erased that unfortunate part of the past. Rocket engines don't need to feel inefficient at family gatherings with their jet engine cousins anymore.
Maybe you didn't notice, air breathing rocket motors exist now. Previously thought impossible, a rocket motor with both ends open. Yes, one end suctions air with incredible force, the other end expells a mixture of super-heated air and propellant.
Currently Fenris is patent pending. Critical details and information will be concealed until at patent is issued. The Fenris team will be conducting fundraising to scale Fenris to full potential in the near future. Stay tuned for more information. With or without additional external funding, the Fenris team will continue with R&D and test activities.
