摘　　要：用离子探针和压电传感器在高压燃烧器中对5／7、6／7、7／7火药床的对流燃烧过程进行了实验研究。成功地获得了火焰阵面曲线和火焰传播速度以及压力波传播和反射等现象，揭示了粒状火药床对流燃烧过程的燃烧机理，并研究了点火强度、装填密度、火药尺寸等因素对燃烧过程的影响。实验结果对火箭推进系统和火炮膛内产生灾难性异常压力机理研究有实际意义。Experimental studies of the convective combustion of granular propellant beds of 5/7,6/7,7/7 are carried out with ionization probes and piezoelectric transducers in a high pressure combustor.The flame front and its velocity and pressure are successfully obtained.The mechanisms of burning in a convective burning processes are revealed.The effects of ignition strensth,loading density and propellant size on the burning processes are also investigated.The expertimental results play an important role in investigating the mechanisms of abnormal pressure in rocket propulsion systems and gun propulsion systems.
