- 在液体火箭推进系统中，贮箱增压系统为推进剂正常供应提供重要的技术保障。温度作为一项重要的影响参数，其高低变化直接决定着增压系统能否满足发动机正常工作的设计条件。本文以某贮箱增压系统为研究对象，开展温度对增压系统的压力特性影响的试验研究，主要分析从室温至-50 ℃低温环境的系统压力参数变化情况。试验结果表明：随着温度的降低，系统在相同工况下压力特性明显增大；-35 ℃是该系统不采取任何措施情况下能正常工作的最低环境温度；针对-35 ℃以下低温环境出现的问题，提出了相应的改进措施，使系统使用温度范围显著扩大，并通过试验验证了改进方法的合理性与有效性。试验结论可为同类增压系统设计及分析提供借鉴。
- Abstract:
- The tank pressurization system is an important constitute of liquid rocket propellant system which controls the pressure and volume flow rate of propellants feeding to the engine. The temperature is a key parameter which determines whether the pressurization system can work naturally or not. In this research, the pressure characteristics of tank pressurization system under different temperatures are analyzed by experimental method. The results show that the pressure characteristic increases with temperature decrease from room temperature to -50 ℃; -35 ℃ is the critical temperature that the system can not work below this threshold value without any improvement measures; some corresponding countermeasures are proposed to deal with the problem occurring when the temperature is below the critical temperature, and available temperature range is expanded to -50 ℃ which satisfy the
