Abstract

Abstract: In order to shorten the time of fuel and air mixture(FAM)filling in pulse detonation engine(PDE) operation process,a multi-detonator PDE with reasonable construction is designed,and it has shown good performance.The FAM filling is along the radial direction and governed by a rotary-tube.This characteristic makes the FAM filling process finished in a short time and saves time for detonation process,and it is helpful for improving the prototype operation frequency and efficiency.

摘要： 为了缩短脉冲爆震发动机工作过程中混气充填时间,采用旋转筒控制爆震室径向进气,设计了结构更为合理的多爆震室PDE试验原型机。该原型机可以在较短时间内完成爆震室的混气充填,为热态爆震燃烧过程留出更充裕的时间,对提高PDE工作频率和整机性能有促进作用。
