| 摘 要： | 本文对膜片处起爆的氢氧爆轰驱动的概念作了简要描述。爆轰波在管端盖板上的反射压力峰值高出初始压力200多倍,在高起始压力条件下产生的如此高的反射峰压对设备安全极为不利。串接在驱动段末端的卸爆段既能消除高的反射峰压,又能延长有效驱动时间。实验结果还表明:爆轰波后气流的定常性和重复性品质优良。用爆轰驱动来产生高焓(具有高压)试验气流是一种高性能且节省费用的新方法。还可用来获得高雷诺数高马赫数试验气流。爆轰驱动具有广阔的应用前景。

| Abstract: | The idea of a driver utilizing gaseous detonation initiatedat diaphragm is described.The pressure peak of reflected detonationwave from end plate of driver section is over 200 times of initial pres-sure.It is dangerous while such high pressure acts upon the end plate.A damping tube attached to driver section can both reduce the load ofthe structure and delay the effective driving duration.Experimentalresults show that the steadiness and the repeatability of the flow be-hind detonation wave are excellent.The detonation driving technique isa high performance and cheap approach for producing high enthalpyflow with high pressure and the high Re number test flow. |
