Research on tip clearance control and structure optimization of high pressure compressor under maneuvering load
Taking a mature engine as an example,the influence of high pressure compressor casing structure on tip clearance was analyzed.Specifically,a calculation model was established with a mature engine as the object.The influence of compressor casing structure on tip clearance under maneuvering load was summarized by finite element numerical simulation,and the casing structure was optimized to improve the deformation of the casing under maneuvering load.Through structural optimization,the radial deformation and relative ovality of the inner casing can be reduced,and the adverse effect of the dynamic load on the tip clearance can be reduced.
