摘要/Abstract

摘要： 为了缩短脉冲爆震发动机燃料/空气混气的充填时间,设计加工了旋转筒控制间歇进气的多爆震室PDE原型机,并开展了试验研究。试验结果表明,原型机在总频率60Hz条件下可以稳定间歇工作,并且产生了450N的正向推力。 

Abstract: In order to shorten the time of fuel and air mixture(FAM)filling in pulse detonation engine (PDE) operation progress, a multi-detonator PDE with FAM radial filling is designed. The experimental results showed that the PDE prototype can steadily and periodically operate at the overall frequency of 60Hz, and the forward thrust of 450N is obtained. 
