RPS has completed its first “Centurion” rocket engine prototype for small satellite space launch vehicles. The engine weighs 33 pounds and costs $100,000 to produce. It is designed to operate on clean burning liquid oxygen and liquid methane propellants and produce 3,300 pounds of thrust. The engine features a fuel-rich staged combustion cycle giving it the ability to perform at high specific impulse, reliability, reusability and scalability to future higher thrust levels. RPS thanks NSF, AFRL Edwards, USSF Threat Reduction Agency, NASA Marshall, NASA Stennis, Reaction Dynamics, Purdue and other distinguished space industry experts for supporting us in Phase I of this project. We are looking forward to hot-fire testing of this engine in Phase II to validate its performance and transition to mass production.
