摘要
为了为今后空间太阳能热动力发电系统的设计提供热能有效利用方案,提出了空间太阳能热动力发电系统的评价准则,建立了系统质量计算的数学模型,利用复形法编制了太阳能热动力发电系统的优化程序,运用该程序对太阳能热动力发电系统进行了全局优化分析,得到了系统各参数的最佳值和最佳工况下的系统部件质量。研究结果表明,全局优化可使系统发射总质量下降11.1％;发射总重量的评价准则综合考虑了系统质量和阻力面积,能够全面反映系统的经济性能,可以得到很好的优化结果。
In order to provide a optimum scheme for the design of space solar dynamic power system, a assessing criterion of space solar dynamic power system is proposed according to the actual need of the space station ,then the mathematical and physical model for the energy balance and mass calculations is set up. Complex method is used to search for the optimal values of every parameters.. By the global optimization of space solar dynamic power system, the optimum value of parameters and the total launched weight were gained. The optimum total launched weight decreased by 11.1% than the average total launched weight. The results indicated that total launched weight is a effective assessing criterion which can combine both system mass and resistance area into a unified criterion.
