Analysis of the Influence of Structural Parameters on the Aeroelastic Stability of Rotor Blades

A comprehensive numerical model of a rotor blade is developed, which incorporates a coupled analysis of the blade's aerodynamic and structural behavior. The model is utilized to investigate the effects of various parameters, including blade stiffness and balance mass, on the aeroelastic stability of the blade. To validate the model, experimental data from previous studies are employed.The results of the numerical simulations demonstrate that the aeroelastic stability of the rotor blade is significantly influenced by its structural and aerodynamic properties. The study reveals that blade stiffness is the most critical parameter affecting the aeroelastic stability, followed by balance mass. Furthermore, the study highlights the substantial impact of the interaction between these parameters on the blade's stability.The innovation of this study lies in the development of a comprehensive numerical model that enables the investigation of how structural parameters influence the aeroelastic stability of rotor blades. The findings provide valuable insights for optimizing rotor blade design and enhancing rotorcraft performance. Moreover, the study emphasizes the importance of considering structural parameters in rotor blade design. It holds practical significance for researchers and engineers involved in rotor blade analysis and design. Future work could focus on exploring the influence of additional parameters, such as blade tip speed and blade twist, on the aeroelastic stability of rotor blades.
