- 摘要:
- 根据无毒推进剂泵压式变推力发动机系统方案，建立了组件数学模型，在此基础上进行了工作过程仿真计算，并对主要影响因素进行了分析。结果表明：发动机各组件能协调工作，但起动加速较慢，发动机变推力时阶跃响应较长；起动箱气腔容积越大，起动越快。
- Abstract:
- The mathematical models of the main components are established based on a nontoxic propellant pump-fed variable-thrust engine system in this paper. Then the simulation is carried out according to the models and the main influence factors in the working process are investigated. The results indicate that the engine subassembly can work harmoniously, but the start-up process is slow. The jump time is long when the engine varies thrust. Larger valume of start-tank results in less start-up time.
