本文提供一种用于控制叶顶泄漏流的转子结构和动力系统。转子结构包括机匣、轮毂和转子，轮毂可转动地安装在机匣内，转子位于机匣和轮毂之间、并固定在轮毂上；转子的叶顶设有第一波浪面，机匣的内周面设有第二波浪面，第一波浪面与第二波浪面以设定间隔g相匹配。实验发现，转子随轮毂在机匣内沿机匣的周向转动的过程中，第一波浪面和第二波浪面之间的设定间隔将原本完整连续的大泄漏涡打碎成了多个不连续的小泄漏涡，叶顶泄漏流损失会降低；另外，转子与机匣发生轴向相对位移时，机匣与转子之间的间隙分布并不均匀，与转子和机匣通过圆柱曲面匹配的方案相比，泄漏流流量和叶顶泄漏流损失会降低。 The invention provides a rotor structure and a power system for controlling blade tip leakage flow. The rotor structure comprises a casing, a hub and a rotor, the hub is rotatably mounted in the casing, and the rotor is located between the casing and the hub and fixed on the hub; a first wave surface is arranged on the blade top of the rotor, a second wave surface is arranged on the inner circumferential surface of the casing, and the first wave surface and the second wave surface are matched at a set interval g. Experiments show that in the process that the rotor rotates in the case along the circumferential direction of the case along with the hub, the set interval between the first wave surface and the second wave surface breaks an o
