| 摘 要： | 研究了带气动阀PDE的供油自适应控制优化设计，通过在油管中设置单向阀和通过油管自身(无单向阀)，成功实现PDE的供油自适应控制，在爆震管直径为180mm，长度为2m，管内流速为25m／s的PDE中，可以产生稳定的爆震波，并获得2MPa以上的压力和1500N以上的峰值推力。通过对不同油管长度、不同工作频率的压力、推力曲线对比研究，分析了供油自适应控制的机理，及供油相对进气滞后时间的长短对PDE工作的影响。

| Abstract: | The principle of optimized fuel self-fit control in pulse detonation engine with aerovalve was investigated. By setting a one-way valve(or without the one-way valve) in the fuel pipe ,and adjusting the distance between one-way valve and atomizer (or between supply throttle and atomizer),optimized fuel self-fit control of the PDE was achieved .Successive detonation was obtained with peak value exceeding 2.0MPa and 1500N for pressure and net thrust curve respectively in a 180mm diameter and 2m long PDE in which the flow velocity is 25m/s.Based on analysis of variational curves of pressure and thrust with different fuel pipe length and PDE working frequency,the mechanism of fuel self-fit control was studied,and the vital influence of the fuel supply delayed time relative to air entrance to PDE working is discussed. |
