摘　　要：高温气冷堆氦气轮机循环被认为是将来核能发电领域中最有潜力的方案之一。首先对高温堆氦气轮机循环进行分析和优化 ,然后着重从热力学和气体动力学角度研究氦气轮机的基本特性。结果表明 ,氦气轮机有两个主要设计特点不同于通常的燃气轮机 :一个是叶片级数多 ;另一个是叶片高度低 ,这些特性分别由氦气的物性和闭式循环的高压所导致。The High temperature gas-cooled reactor (H TG R) coupled with helium turbine cycle is considered as one of the leading candida tes for future nuclear power plants. In this paper, the HTGR helium turbine cycl e was analyzed and optimized. Then the focal point of investigation was concentr ated on the fundamental thermodynamic and aerodynamic features of helium turboma chine. As a result, a helium turbomachine is different from a general combustion gas turbine in two main design features, that is a helium turbomachine has more blade stages and shorter blade length, which are caused by the helium property and the high pressure of a closed cycle, respectively.
