摘要

在热机家族中，燃气轮机的独特之处在于它被用来产生两种不同的有用动力。通过将燃烧的燃料热量转化为功，燃气涡轮发动机可以产生外部轴动力(例如，驱动连接的发电机)或喷气动力(例如，作为喷气发动机，产生推力以推动飞机)。这意味着燃气轮机的热力学指标，热效率，是多方面的，需要细致入微的检查。

Aspects of Gas Turbine Thermal Efficiency

In the family of heat engines, the gas turbine is unique in that it is used to produce two different kinds of useful power. By converting combusted fuel heat into work, a gas turbine engine can produce external shaft power (e.g., to drive a connected electric generator) or jet power (e.g., as a jet engine, to produce thrust forces to propel an aircraft). This means that the gas turbine’s thermodynamic figure of merit, thermal efficiency, is multifaceted, and calls for a nuanced examination.
