摘要
液氢/液氧等低温推进剂,由于其高性能优势被作为深空探索使用推进剂,但低温推进剂长时间在轨应用,主要受限于低沸点的推进剂受热蒸发所带来的贮箱压力控制和蒸发损失等一系列问题,需要发展低温推进剂无损贮存技术来解决。文章介绍了应用低温制冷机结合换热技术实现贮箱内低温推进剂无损贮存的试验情况,总结其发展趋势和展望。
Cryogenic propellants such as liquid hydrogen(LH 2)and liquid oxygen(LO 2)are the first choice for future space exploration plans due to their high specific impulse for rocket motors of upper stages.However,the low storage temperatures of LH 2 and LO 2 cause substantial boil-off losses and the pressure control of tank for long duration missions.The technology of zero boil off(ZBO)was developed to resolving the two main problems.This test series established that the active cooling system integrated with the propellant tank eliminated boil-off and robustly controlled tank pressure.The progress of experimental study on active cooling system for zero boil-off storage of cryogenic propellant are summarized,and some conclusion and suggestion on ZBO technologies for cryogenic propellant are proposed.
