- 摘要:
- 太阳能热推进采用小分子量气体作为推进剂可以获取800~900 s高比冲，但提高推进系统的换热效率是目前亟待解决的问题。本研究建立了太阳能热推进系统主要部件的基本分析模型，在利用有限单元法进行热分析的基础上，对系统在多种工况下的相关参数进行了计算，分析了各部件主要参数对提高太阳能热推进系统热效率和推进效率的影响，得出了系统效率在不同工作状态下的变化规律，并提出了提高系统效率的措施。
- Abstract:
- Solar thermal propulsion system can provide a high special impulse of 800 s～900 s when it takes small molecular weight gas as propellant, but it is a significant issue to improve the heat transfer efficiency of the thermal propulsion system. The basic analysis models of main parts in the solar thermal propulsion system were built. Based on thermal analysis performed by using the finite element method, the correlative parameters of the system at different working conditions were calculated. The influence of the main parameters of each assembly unit on the improvement of thermal efficiency and propulsive efficiency of the solar thermal propulsion system was analyzed. The change rule of system efficiency in different working status was achieved. The measures to improve the thermal efficiency of the system are proposed in this paper.
