Abstract: To investigate the performance of gas turbine engines using wave rotor combustion，one dimensional analysis of aerodynamical was performed and thermodynamical cycle model was established to verify the performance improvements and analyse the effects of parameter on the overall performance and eventually applied to an active service vortex rotor shaft engine. Results indicate that wave rotor combustion can significantly enhance the overall performance of gas turbines. The specific cycle work maximally increases by 39% and specific fuel consumption decreases by 28%，compared with the benchmark gas turbines. In view of design and optimization，the influence of loop parameters was taken into account. Improving the turbine inlet temperature can improve the performance of the engine. An optimal compressor pressure ratio exists. The higher the temperature of the turbine inlet，the greater the optimal compressor pressure ratio. Comparing and analyzing five different wave rotor-topping cases indicates keeping the compressor，turbine inlet temperature constant is a way to improve performance maximally.

摘要： 为研究内燃波转子发动机性能变化规律，建立内燃波转子发动机的气动热力循环分析模型，开展了内燃波转子对燃气轮机总体性能的影响研究，并进行影响内燃波转子发动机总体性能的参数分析，且针对现役涡轴发动机，结合波转子技术，给出5种组合方式。结果表明内燃波转子能够显著地提高燃气轮机的总体性能，循环功最大提高39%，耗油率最大降低28%。提高涡轮进口温度可以提高内燃波转子发动机的总体性能；存在使循环功达到最大值的最佳压气机压比，且涡轮进口温度越高，最佳压气机压比越大。在基准燃气轮机与内燃波转子的组合方式中，保证压气机部件以及涡轮进口温度不变，能最大限度地提高燃机轮机的性能。
