Mode Transition from Turbojet to Ram / Scramjet (MoTr)
Program Goals and Objectives – Ground test an integrated Turbine Based Combined Cycle
propulsion system using hydrocarbon fuel to validate the transition from turbojet to ramjet/scramjet in a hypersonic propulsion system
Technical Approach– Complete current FaCET and HiSTED testing– Design TBCC model leveraging DARPA investments in
hypersonics:– HTV-3X: configuration– HiSTED: Mach 3.5+ turbine engine– FaCET: propulsion flowpath & ramjet/scram– Select test facility and modify to meet demonstration
objectives – Complete TBCC mode transition test
Military Utility– Hypersonic systems offer the opportunity of a disruptive
technology to support national security objectives including ISR, strike, and access to space
– Successful completion of this ground test is critical to enabling
unassisted, air-breathing hypersonic flight
