A hybrid electrically controlled rotor based on macro-fiber composite (MFC) was proposed. To explore the feasibility and control characteristics of this hybrid ECR, an aeroelastic dynamics analysis model was first established based on moderate deflection beam theory combined with the piezoelectric constitutive equations of MFC. Subsequently, using this analytical model and focusing on the MFC model rotor, simulation studies were conducted to investigate the influences of key control and design parameters on the rotor’s control response. With a design target of achieving a cyclic pitch range of ±12°, the feasibility of utilizing MFC for cyclic pitch control in the hybrid electrically controlled rotor was analyzed. The simulation results indicated that by increasing the MFC driving voltage, adding more MFC layers, and reducing blade torsional stiffness, the elastic torsional control authority of the hybrid electrically controlled rotor can be effectively enhanced. Meanwhile, the model rotor blade tip can achieve a maximum 1 Ω torsional angle of approximately ±12°, meeting the initial cyclic pitch design objective.
