Abstract:
This paper researched into the high-Mach property about the air turbo ramjet. It established the model of engine performance,analyzed the influence among the inlet,gas combustion and outlet to engine property,simulated the ATR engine internal flow field in the same working state,accomplished the free jet tests. Comparing the test result with the simulation result,it validated the veracity of high-Mach property. Research results indicate that ATR engine can work smoothly on 3.5 Ma and provide preferable performance. The turbofan can improve the flow pressure obviously. The inlet always has a steady and startup state. The thrust gain of the engine accords to anticipations.
