通过试验测出贫氧推进剂中嵌金属絲的燃速规律与一般推进剂内嵌入金属絲的燃速规律类同,但燃速提高倍数较小,这主要是由于燃气温度较低。采用通常所用的中断设备,得不到中断药柱,采用大流量的水强迫冷却燃面,代替过去剩药自由落入水箱的常规方法,克眼了剩药在水中继续燃烧不熄火的问题,从而改进了中断燃烧的实验手段。通过试验发现金属絲露头长度与直径有一定关系,这为进一步开展理论研究提供了有价值的资料。
The burning rate of embedded wires in oxygen-poor pro-propellants was found to be similar to the burning rate of wire embedded in common propellants. However, the burning rate was smaller, which was mainly due to the lower gas temperature. The use of commonly used interrupt equipment, no interruption of drug column, the use of large flow of water to force the cooling surface, instead of past the traditional free fall into the water tank conventional method, guessed the left medicine continued to burn in the water does not flame out, Thus improving the experimental means to interrupt combustion. It is found that the length and diameter of wire outcrop have some relationship with each other, which provides valuable information for further theoretical research.
