Development of Ultra-Micro Ultra-Highly-Loaded Axial Turbine

为了研究大转角超高负荷涡轮叶栅对超微型燃气轮机的适用性，在超高负荷涡轮叶栅试验台上进行了气动性能试验。此外，还对叶片型线、入射角等参数对超高低温涡街内的流动进行了数值计算。实验结果表明，UHLTC在低流速区表现出较高的性能，因此适合于UMGT。计算结果为UHLTC气动性能的提高提供了有用的信息。

In order to investigate the applicability of an ultra-highly loaded turbine cascade(UHLTC) with high turning angle to ultra-micro gas turbines(UMGT), the aerodynamic performance tests were performed experimentally with the annular turbine cascade test rig with UHLTC. Moreover, the numerical calculations were carried out for the flow in UHLTC with the parameters such as the blade profile and incidence angle. The experimental results clarified that UHLTC exhibits the high performance at low flow rate region, and consequently is suitable for UMGT. The computed results provided the useful information for the enhancement of the aerodynamic performance of UHLTC.
