煤油/空气气动阀式脉冲爆震发动机试验

为了研究煤油/空气气动阀式脉冲爆震发动机(简称PDE)的爆震波特性,建立了一整套试验系统,在进气加温和燃油加温的条件下,以液态煤油为燃料、以空气为氧化剂,在内径100 mm、长为2000 mm的爆震管内进行了大量的多循环爆震试验。研究了液态煤油和低污染空气(接近纯空气)形成的可爆混气的爆震波特性,研究了气动阀和空气加热器的设计方法等。研究结果为进一步研究液态燃料和高污染空气形成可爆混气的爆震燃烧机理提供了依据,为研制工程应用的PDE提供理论和实践基础。 

Experimental Investigation on Kerosene/Air Pneumatic Valve Pulse detonation Engine

In order to investigate detonation wave charcteristics of kerosene/air pneumatic valve pulse detonation engine,a complete set of test facility was established.A lot of multi-cycle detonation experiments were carried out using a detonation tube with 100 mm inner diameter and 2000mm length,filling with heated liquid kerosene and air as detonable mixture.The detonation wave characteristics of kerosene and low polluted air as detonable mixture were investigated.This investigation is of importance to study kerosene and heavy polluted air as detonable mixture in depth and to provide theoretical and practical basis for the development of PDE's engineering application.
