Through the structure design, the design of machined structure intermediate casing testpieces solves the complex with support plate complex structure intermediate casing passage and support plate cannot realize through machine tooled. After conducting machined structure intermediate casing performance test, we compare the result with theoretical design, check test and design compliance, which provides the basis for testing intermediate casing design. Furthermore, though comparing and analyzing the results of routine casting structure intermediate casing testing, we obtain the deviation the deviation between the routine casting intermediate casing testpieces test results and actual value. The result shows that: under the same passage designs state, the intermediate with machined passage has the better performance testing result and design compliance. he intermediate casing with passage of machined surface has the higher total pressure recovery coefficient than the one with casting passage by 1.5 to 2 percentage
