| 摘 要： | 阐述了低温发动机起动前推进剂入口温度对试车的重要性,分析了以往试车入口温度过高的原因。通过对试验系统的改造,采用强迫排放推进剂的方法,降低发动机入口推进剂温度,保证发动机在起动前推进剂入口温度满足试验要求。经试车验证,所采取措施成功解决了试验系统存在的推进剂入口温度过高的问题。

| Abstract: | Factors affecting the propellant inlet temperatures during liquid rocket engine tests were analyzed.Methods were adopted for reducing the propellant inlet temperature by modification of the test system and forced dump cooling of the propellant.Tests proved that the improved approaches are effective and the propellant inlet temperature meets the requirement very well. |
