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.
