摘要
闭式布雷顿循环在航空航天电源系统中有着应用前景。文中用有限时间热力学方法研究恒温热源不可逆闭式简单布雷顿循环的性能，导出其最佳功率与效率间的关系，所得结果比经典热力学优化结果更具意义。
A potential application of closed-cycle Brayton plants for aerospace electrical power system is presented. The performance optimization of a simple irreversible closed-cycle Brayton plant is studied by using finite-time thermodynamic methods in this paper. The optimal relation between power output and efficiency of the irreversible cycle is derived. The results are more significant than those by classical thermodynamic methods.
