A single-passage fluid-thermal and full-passage thermo-structural coupling modeling method was established, and three-dimensional fluid-thermal-structural coupling analysis of a turbojet engine was carried out. Compared with the method without coupling, there were great differences in temperature, stress, and deformation. The temperature of the compressor impeller of the fluid-thermal coupling method was 15 K lower than that of the uncoupled, and the temperature of the three-stage diffuser was 10—20 K lower than that of the uncoupled. The maximum equivalent stress of the compressor impeller of the thermal-structural coupling method was 31 MPa (4.7%) smaller than that of the uncoupled, and the radial deformation of the compressor impeller was 0.02 mm (11.1%) larger than that of the uncoupled. The tip clearance variation of the turbine at the design point predicted by the fluid-thermal-structural coupling analysis was 0.54 mm. This method realized the analysis of the temperature field, stress field, and deformation field of the whole engine, comprehensively evaluated the strength and deformation of components, and provided data support for component optimization.
