摘　　要：采用经验数据和计算相结合的方法预估直径180 mm,长度为2.2 m带气动阀的脉冲爆震发动机(Pulse Detonation Engine,简称PDE)的性能,并考虑PDE内的总压损失.计算结果和实测结果基本吻合.计算中发现,由于考虑了PDE内总压损失,PDE推力比理想情况低,油耗比理想情况大.该计算方法对预估实际PDE工作性能具有较大的参考价值.　The performance of Pulse Detonation Engine（PDE） with aerovavle of diameter 180 mm、length 2.2 m was pre-estimated by using a method combining experiential data and computation,at the same time the total pressure loss inside the PDE was taken into account.The computational results basically match the results obtained from the experiments.It was found that the thrust of PDE was lower than that in ideal case and specific fuel consumption（SFC） was larger than that in ideal case,due to that the total pressure loss was considered.This computational method is valuable for pre-estimating the performance of PDE in actual operation.
