摘要/Abstract

摘要： 利用开环控制系统,在直径180mm,长度2000mm,采用气动阀模拟飞行进气、燃用汽油的脉冲爆震发动机(PDE)样机上,对PDE的工作过程控制和协调进行了试验研究,得到了在不同的PDE工作过程时间分配下的试验结果,由此详细分析了在开环控制的情况下,PDE协调工作的条件及不能正常工作的原因,为PDE的设计和控制系统的研制提供重要的参考价值。

Abstract: By using opened-loop controler for multi-cycle pulse detonation engine (PDE) with a detonation tube 180mm in inner diameter and 2000mm in length,and by filling liquid gasoline and air into the tube as detonable mixture by aero-valve,experiments were performed.Available testing results of the various time schedule of a PDE operation cycle were obtained.Theoretically the reasons of inconsistant working of opened-loop controled PDE detailedly.Theoretical analysis provides important useful insight for PDE working process.
