Fluid-solid coupling and flight mechanics simulation processing method

A processing method for fluid-solid coupling and flight mechanical simulation belongs to the field of mechanical simulation, and is characterized in that the fluid-solid coupling of local deformation/control surface manipulation is decomposed into grid deformation and grid overall motion to respectively carry out step-by-step calculation of motion and deformation; and the calculation results of motion and deformation are used as iterative calculation input parameters of the next time step, so that the fluid-solid coupling and flight mechanics integrated simulation technology of local deformation/control surface manipulation is realized. High-fidelity discretization is realized. High-precision calculation is realized. Lcal large deformation of the grids is realized; nonlinear flow characteristics in flight/navigation can be considered. An N-S equation fully describes the phenomenon of unsteady and nonlinear flow at high angles of attack and bluff bodies. Nonlinear factors of structuraldeformation can be fully
