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。 In order to shorten the time of mixed gas filling during the operation of pulse detonation engine, the rotating cylinder was used to control the radial intake of detonation chamber. The multi-detonation chamber PDE prototype with more reasonable structure was designed. The prototype can be completed in a short time filling the degassing chamber detonation chamber, leaving ample time for hot detonation combustion process to improve PDE operating frequency and the overall performance of a promotion.
