Project Osiris is a regeneratively cooled engine with active thrust vector and throttle control capability. 

Engine Requirements:

  • The engine shall provide a thrust of at least 2.23 kN.
  • The engine shall be capable of throttling down to 40% of nominal thrust, hold constant for 2 seconds, and then return to nominal thrust.
  • The engine shall be capable of thrust vectoring at least 7 degrees in all directions.
  • The engine shall be capable of completing a circular thrust vector profile in at most 10 seconds.
  • The engine should be completed over a one year design, manufacture, and test cycle.
  • The engine should be capable of a minimum of 30 hot fires without requiring major refurbishment or component replacement.
