The performance of the CFM56 engine is also directly impacted by the improvement of high pressure turbine structure design.So,the enhancement method of the high pressure turbine efficien-cy could be analyzed with the finding of differences of high pressure turbine structure design.To solve this problem,firstly the design characteristics of four main parts of high pressure turbine of the early CFM56 3 engine are introduced.And then the different improvement measures of high pressure turbine engine structure design of CFM56 5A,CFM56 5C and CFM56 7 series engine are analyzed respec-tively from three aspects of the blade material,blades-turbine cooling and active clearance control,and the development direction of high pressure turbine structure design is summarized.
