摘要
To maintain acceptable thrust and fuel consumption over a wide flight spectrum, combined cycle engine is a favoured solution for high speed air breathing propulsion. Regarding to low impulse of rocket engine, thrust loss of turbine engine at high speed, as well as thrust loss of ramjet engine at low speed, a unique three-channel (turbinerocket-ramjet) combined cycle engine was suggested. In the present work, the three-channel inlet was designed for a wide Mach range 0-6. From takeoff to Mach 2, the three channels were all open, but only with the turbine engine working. From Mach 2 to 4, the turbine channel was closed whereas the other two channels were both open and working. For Mach number over 4, only the ramjet engine was left to work.
