| Abstract:In order to reduce the compressor casing weight by changing the casing material, structure form and manufacturing method,
according to the principle of the skeletal supporting frame structure, the improved design of skeletal supporting frame structure for a
compressor casing was conducted, which was truss structure. The simulation and comparative analysis of three kinds of typical structure
casing were performed respectively from the static stress, mode and containment capability, and the best scheme was obtained at present
that was circular opening casing. The result shows that the skeletal supporting frame should reduce the compressor weight as 10%~20% to
improve the engine thrust-weight ratio, which has no influence on casing application requirement. |
