Saturation phenomena and nonlinear resonances of rotating pretwisted laminated composite blade under subsonic air flow excitation

The purpose of the present investigation is to reveal the saturation phenomena and the primary resonance of a rotating pretwisted laminated composite blade subjected to a subsonic airflow excitation in the case of 1:2 internal resonance. The flexible compressor blade is treated as a rotating laminated composite cantilever rectangular plate clamped on the rigid disk with the pretwisted and the preset angles. The subsonic air flow is regarded as...
