Actuation Optimization for Macro-Fiber Composite Bonded Smart Fan Blade of Airplane Engine

The strong blade vibration in the airplane engine causes high alternating stress, which leads to low fatigue life and flight risk. The investigation of its vibration characteristics and reduction approach is crucial in the aircraft engine design and operation. This paper proposed a MFC bonded smart fan model based on the large deformation of plate theory. The feasibility of MFC patch is verified through the comparison between the numerical results with the literature ones. Finally, the patch rotation and fiber orientation is optimized through a parametric study, which provides valuable reference for the vibration reduction of the airplane blades.
