Abstract: A model of cartridge starting of turbofan engines is developed by accounting for the effect of characteristics of the embedded inlet and flying condition. The theoretic and experimental investigation has been done for seeking the reliability condition of cartridge starting of turbofan engines, which is matched with the embedded inlet. The simulation results and testing data indicate that there are a critical Mach number and a critical attack angle, either of which has a decisive influence on the reliability of cartridge starting of turbofan engines.

Key words: embedded inlet, turbofan engine, cartridge starting, cartridge starting condition
