摘要
设计了一台内径90 mm、外径200 mm、长度1500 mm,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40 Hz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.
A sector-PDE （pulse detonation engine） with an internal diameter of 90 mm and an external diameter of 200mm was designed. Its length is 1500mm 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 oil 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 reflee tor has high performance on initiating detonation.
