Abstract: In order to solve the problem of rotor-rotor inter-shaft labyrinth seal rubbing fault during the test run of a counter-rotating dual-rotor aero-engine, based on the fast Fourier transform, the vibration time-domain signals ...

Abstract: The aero-engine casing is a key component for carrying loads. With the purpose of improving the thrust-weight ratio of the aero-engine, the casing is required to be designed to be as thin as possible. Therefore, the vibration ...
