摘要
为了降低系统的质量和阻力面积,运用系统分析的方法,建立了空间站太阳能热动力发电系统的物理和数学模型,提出了发射总重量的系统性能评价准则,并对不同条件下的系统部件质量进行了数值模拟,分析了不同操作参数对系统部件质量的影响规律。研究结果表明,操作参数对系统部件质量有正负两方面的影响,优化这些参数可以明显降低系统的发射总质量。
In order to reduce the system mass and resistance area, the mathematical and physical model of space solar dynamic power system is made using the method of system analysis, a new assessing criterion, total launched weight, is proposed to combine the system mass and resistance area into a unified criterion. The numerical simulations on the different condition are performed and the effect of the operating parameters on the system mass is analyzed. The results of the study indicated that there is positive and ...
