| 摘 要： | 设计了一台内径90mm、外径200mm、长度1 500min,扇形角约为60.的气动阀式扇形PDE,试验研究了孔板式气动阀和旋流式气动阀两种结构的工作特性,成功实现了扇形PDE在两相混气中最高40Hz频率连续工作;研究了扇形管内不同结构激波反射器对爆震波触发的影响,试验发现,逆流安装的激波反射器对爆震波触发有利.

| Abstract: | A sector-PDE(pulse detonation engine) with an internal diameter of 90 mm and an external diameter of 200 mm was designed.Its length is 1 500 mm and its sector angle is 60°.Two types of air-valves(orifice type and vortices type,respectively) were used to get appropriate mixture of air and oil,and their performances on detonation were compared.The results indicated that the designed PDE could operate at a frequency up to 40 Hz.In addition,the text gives the results of different shock-wave reflectors' comparison: the inverted reflector has high performance on initiating detonation. |
