对转涡轮技术是有效提高发动机功率密度、效率，减少陀螺效应的重要技术手段之一，但其设计难度大，在实际工程应用中仍面临一系列技术挑战。本文主要从对转涡轮在不同领域中的应用、气动设计及性能分析、内部流动分析及优化和气动试验技术四个方面对近十年来国内外对转涡轮气动技术的研究进展进行综述，并指出未来应进一步深入认识不同类型对转涡轮内部复杂流动机理及调控方法，加强试验技术研究，为实现对转涡轮在不同领域中的应用提供技术支撑。

The contrarotating turbine technology is one of the important technical means to effectively improve the power density and efficiency and to reduce the gyroscopic effect for engines.However,due to the difficulty of its design,it still faces a series of technical challenges in practical engineering application.The domestic and foreign development of the research about the contrarotating turbine aerodynamic technology in recent ten years are reviewed in four aspects,including the application of the contrarotating turbine in different fields,the aerodynamic design and performance analysis,the internal flow analysis and optimization and the aerodynamic experiment technology.Besides,it is pointed out that,in the future,it is necessary to deeply understand the internal complex flow mechanism and regulation methods of different types of contrarotating turbines,and to strengthen the experiment technology research,so as to provide the technical support for the application of the contrarotating turbine in different fields.
