| 摘 要： | 设计了内径分别为60、70mm的两组吸气式两相脉冲爆震发动机,在略高于常压状态下成功进行了以汽油为燃料、以空气为氧化剂的吸气式两相脉冲爆震发动机原理性试验.进气道内采用无阀的进气结构,试验中在爆震管内部安装Shchelkin螺旋来促进爆震波的生成,所测量的爆震波接近充分发展的C-J爆震波.内径60、70mm的发动机最高工作频率分别为15、20Hz.进气道内压强变化幅度在0.1MPa左右,说明所设计的进气道与爆震管匹配良好,这将为脉冲爆震发动机用于工程实际提供技术储备.

| Abstract: | Two air-breathing two-phase Pulse Detonation Engines(PDEs) had been designed whose internal diameters were 60mm and 70mm respectively.In the conditions of the pressure a little higher than 1 atmosphere,the PDEs were tested and run on gasoline-air mixture.There was a valveless structure in inlet channel.Shchelkin spiral was fixed in detonation tube to enhance the production of detonation wave.The measured pressure of detonation wave was close to that of C-J detonation wave.The highest working frequency of th... |
