本文根据片型装药发动机对两种双基推进剂四种复合推进剂在四种药型下的试验结果,分析了在无喷管发动机内压强—时间关系、燃气流速和装药燃速沿通道的变化、特性速度及推进剂特性的影响。论述了推进剂的基础燃速对无喷管发动机工作特性的影响,侵蚀燃烧问题,装药通道内的几何喉面与流场中音速截面的关系等。对无喷管发动内设计有一定参考价值。
Based on the experimental results of the four types of propellants of two double-base propellants under the four drug types, the paper analyzes the relationship between pressure-time, gas flow rate and charge burning speed Channel changes, characteristics of speed and propellant properties. The effects of the basic burning rate of propellant on the operating characteristics of a nozzleless engine, the erosion and combustion problems, the relationship between the geometrical throat surface in the charge channel and the sonic velocity cross section in the flow field are discussed. There is a certain reference value to the design of nozzleless launch.
