波转子技术对涡轴发动机性能的影响

Utilizing Wave Rotor Technology to Enhance the Turboshaft Engine

本文分析了采用波转子技术后涡轴发动机的性能改变,讨论的是典型的四端口波转子加入基准发动机后可采用的五种循环形式,用热力学方法计算了波转子发动机的性能参数。结果表明,采用波转子技术可在保持压气机压比、涡轮膨胀比和进口温度不变的情况下大幅度提高基准发动机性能。

A performance analysis was completed for a small turboshaft engine topped with various wave rotor cycles. Five different advantageous implementation cases for a four-port wave rotor into a given baseline engine were studied. Comparison between the theoretical performance results of wave-rotor-topped engines and the baseline engine shows a significant performance enhancement for almost all the cases studied. The highest gain was obtained in the case when the topped engine operates with the same turbine pressure ratio, inlet temperature and the same physical compressor like that of the baseline engine.
