舱外推进剂管路冗余电加热技术
|
摘要
火箭在飞行过程中上面级推进剂输送管路长时间暴露于舱外,为确保推进剂温度满足要求,设计了一种主动冗余电加热方法。通过热仿真分析,设计了合理的加热功率,可以确保一度故障下管路温度仍在可接受的范围内,并通过热平衡试验进行了验证。验证结果表明:该技术已应用于上面级热控设计中,达到了预期的效果。
The propellant pipe of upper stage exposed in the space long time, to meet the temperature range, in this paper, it a redundancy electric heating method is designed. A reasonable heating power design method is proposed by thermal analysis. It can satisfy the temperature range when the fault occurs of pipe heating tape. The design method has passed the thermal balance test. This technology has been applied in the upper stage.
