为获得弹用涡喷发动机的起动性能参数,设计了发动机地面起动试验系统。系统由发动机试车台、信号采集测量系统、时序控制系统、供油系统、高压吹转系统等分系统组成。利用该系统对某型弹用涡喷发动机进行地面起动试验,获得发动机转速,推力,压气机出口压力等参数,利用试验数据获得发动机起动性能。试验结果表明,该发动机具有快速的起动加速性和较好的起动可靠性。 In order to obtain the start-up performance parameters of the turbo-jet engine, the engine ground-start test system was designed. System consists of engine test bench, signal acquisition and measurement system, timing control system, fuel supply system, high pressure blowing system subsystems. The system was used to test the ground launch of a certain type of projectile turbojet engine. The parameters of engine speed, thrust and compressor outlet pressure were obtained. The test data was used to get the starting performance of the engine. The test results show that the engine has fast starting acceleration and good starting reliability.
