旋翼高效/高精度气弹全耦合分析方法
High-efficiency and high-precision aeroelastic full coupling method of rotor
摘要
Abstract
To balance calculation accuracy and efficiency of rotor aeroelastic coupling analysis,a fully coupling aero-elastic method based on GEBT/VVPM/L-B is established.Structurally,the dynamic model of blade is established by using the Geometrically Exact Beam Theory(GEBT),which effectively consider the large deformation.The Viscous Vortex Particle Method(VVPM)and the L-B dynamic stall model are coupled to consider the viscous flow,the distor-tion of the wake and the unsteady aerodynamics of the airfoil.In each iterative step,the aeroelastic response is in-serted into the aerodynamic computation module in a parametric form to realize the full coupling strategy.The c8534 flight of UH-60A is introduced for verification,and the effectiveness of the aeroelastic coupling method is verified by comparing with the experiment and the CFD/CSD tight coupling result.The results show that the proposed method can improve the computational accuracy significantly relative to the rigid rotor model.Compared with the CFD/CSD cou-pling method,the calculation efficiency can be improved by more than 54 times without apparently affecting the calcu-lation accuracy.The rotor aeroelastic loads can be effectively predicted in solving the strong nonlinear aeroelastic re-sponses,which verifies the robustness of the model.关键词
