Structural design and verification of ceramic matrix composite high pressure turbine shroud

<bold> </bold>For the urgent engineering application demand of ceramic matrix composite in aero engine turbine components, the structural design method of ceramic matrix composite high pressure turbine shroud was studied. The structural design of ceramic matrix composite high pressure turbine shroud was carried out, including contour structure, assembly structure, seal structure, etc. The matching research of different preform schemes and different densification process was completed to achieve the goal of 70% weight reduction of the overall structure of high pressure turbine shroud. The parts test assessment was carried out to identify the failure modes of the ceramic matrix composite high pressure turbine shroud. And the high pressure turbine shrouds were installed on the core engine to complete the test verification, which promoted the application of ceramic matrix composite in aero engine turbine components.
