04.2 - Aerostructures Design, Structural Dynamics, AeroelasticityTURBINE STRUCTURE ANALYSIS AND IMPROVEMENT OF A HIGH-SPEED ROTOR WITH MULTI-DISK AND MULTI-SUPPORTW.-J. Nie¹, W.-Q. Deng¹, Y.-N. Chen¹, L. Zou¹; ¹AECC Hunan Aviation Powerplant Research Institute , China The structures of a high-speed flexible rotor were analyzed, the results showed that the rotor could operate to the rated working speed after the improvement of turbine structure. This study solves a key technology in the engine development, it also provided references for structure design of the true low-pressure rotor of engine and rotors of the same type. |
