以煤油为燃料、空气为氧化剂,采用气动阀门结构进气,组合结构障碍物强化燃烧和双半V型障碍物加强激波反射,在内径100 mm,长为1 340 mm的爆震管内进行大量的爆震试验,实现工作频率58.8 Hz协调工作。研究爆震室内主要部件在不同工作阶段的功能,并分析主要部件的工作机理,分析了煤油/空气两相可燃混气形成过程,研究煤油/空气脉冲爆震发动机爆震波特性,获得煤油/空气脉冲爆震发动机协调工作关键技术。研究结果为煤油/空气脉冲爆震发动机原理样机设计提供了理论基础。
Using kerosene as fuel, air as oxidant, pneumatic valve structure intake, combined structural obstacle enhancement combustion and double half V-type barrier to enhance shock reflection, a large number of detonation tubes with internal diameter of 100 mm and length of 1 340 mm Knock test to achieve the working frequency of 58.8 Hz coordination. The main components of the detonation chamber were studied in different working stages. The working mechanism of the main components was analyzed. The formation process of kerosene / air combustible gas mixture was analyzed. The detonation wave characteristics of kerosene / air pulse detonation engine were studied. The kerosene / air Pulse detonation engine coordination work key technologies. The results provide a theoretical basis for the prototype design of kerosene / air pulse detonation engine.
