Abstract: Aiming at the starting and acceleration performance requirement of pilotless turbojet engine and the safety and reliability of the engine starting and acceleration process,the main influence factors were studied,such as single pump double oil system、gunpowder starter、fireworks igniter and the main solenoid valve. Meanwhile,in order to realize the rapid start of engine function,the open loop control was used in the starting process and the closed loop control was used in the above-idle state. The control scheme was verified by the ground test and the flight test,then the staring time, output speed, exhaust temperature and pressure were acquired. The results indicate that the engine has a good starting and acceleration performance and reliability.

Key words: turbojet engine; start performance; control scheme; ground test; flight test
