COMBINED CYCLE INTEGRATED COMBUSTOR AND NOZZLE SYSTEM

摘要

An engine (20) that operates and produces the entire required vehicle thrust below Mach 4 is useful for a Hypersonic combined cycle vehicle by saving vehicle and engine development costs. One such engine (20) is a combined cycle engine having both a booster (30) and a dual mode ramjet (DMRJ). The booster (30) and the DMRJ are integrated to provide effective thrust from Mach 0 to in excess of Mach 4. As the booster (30) accelerates the vehicle from Mach 0 to in excess of Mach 4, from Mach 0 to about Mach 2 incoming air (28) delivered to the DMRJ is accelerated by primary ejector thrusters (34) that may receive oxidizer from either on-board oxidizer tanks (31 ) or from booster (30) compressor discharge air.
