本文把最优化原理用于载人航天器座舱大气控制系统设计,以系统的重量、体积、可靠性、成本和技术复杂程度为目标,建立了系统及其部组件的目标函数和有关性能计算公式,并用BASIC 语言编制了计算机设计程序,在微型计算机上进行了实例计算,证明本优化设计方法能够用于载人航天座舱大气控制系统总体设计。 In this paper, the principle of optimization is applied to the design of atmosphere control system of manned spacecraft cabin. The objective function and related performance formula of the system and its components are established based on the weight, volume, reliability, cost and technical complexity of the system. , And compiled the computer design program in BASIC language, carried out the example calculation on the microcomputer, and proved that the optimized design method can be used in the overall design of the man-made space cockpit atmospheric control system.
