摘　　要：为了得到六管气动阀脉冲爆震发动机(PDE)的协调工作,在共用进气道条件下,主要采用离子探针技术进行了试验研究,同时对爆震波激波后燃烧波的传播速度进行了定量测量,并用压力传感器进行了试验验证.研究结果表明:在单管频率f=30Hz(总频率f=90Hz)时,六管PDE能够协调、稳定的工作;采用局部蒸发器改善燃油蒸发后,爆震管都达到了爆震波的传播速度.In order to obtain the coordinate operation with six-tube aero-valve p ulse detonation engine（PDE）,ion sensor technique was mainly used to study the ex periment under common air inlet conditions.At the same time,propagation velocity of combustion wave behind shock wave was measured quantitatively and the experi ment was also validated with a pressure sensor.According to the results,the sixtube PDE can work coordinately and continuously at the operation frequency of si ngle pipe 30 Hz（the total operation frequency 90 Hz）.Besides,all detonation tube s reached the speed of detonation wave when the local evaporator was employed to improve the fuel evaporation.
