提出了以高质量分数过氧化氢为氧化剂的泵压式固液火箭发动机的系统仿真和优化设计方法.利用高质量分数过氧化氢易催化分解的特点,建立了采用泵压式输送系统的固液火箭发动机系统仿真模型,并应用遗传算法分别对采用挤压式和泵压式两种输送系统的固液火箭发动机开展优化设计.结果显示:虽然增加了管路系统的复杂性,但在总冲相同时,泵压式固液火箭发动机在质量、体积、比冲等性能上均优于挤压式固液火箭发动机,因此具有更大的工程应用潜力和优势.
A system simulation and optimization design method of pump-pressure solid-liquid rocket motor with high-quality fraction hydrogen peroxide as oxidant is proposed.Using the characteristics of easy-catalyzed decomposition of high-quality fraction hydrogen peroxide, a solid- Liquid rocket engine system simulation model, and apply the genetic algorithm to optimize the design of the solid-liquid rocket engine using two kinds of extrusion system and pump-pressure delivery system.The results show that although the complexity of the piping system is increased, At the same time, the pump-type solid-liquid rocket motor is better than the extruded solid-liquid rocket motor in terms of quality, volume and specific impulse performance, and therefore has greater potential and advantages for engineering application.
