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.

为了研究超高负荷大转角涡轮机叶栅（UHLTC）在超微型燃气轮机（UMGT）中的应用，在超高负荷大转角环形涡轮机叶栅试验台上进行了气动性能试验。此外，还对UHLTC内的流动进行了数值计算，计算参数包括叶片型线和冲角等。实验结果表明，UHLTC在低流量区表现出较高的性能，因此适用于UMGT。计算结果为UHLTC气动性能的提高提供了有用的信息。
