Plug-serving Technology Of Numerical Methods

The prediction of the separation trajectories of the external stores carried out on aircraft is an important task in the aerodynamic design area. The chimera embedding technique is presented for the external store separation configuration. It divides the whole region into many subdomains. Euler equations are used for every subregion with the finite volume method. Through couple iterating, the solution of whole field is obtained by exchanging information between subregions.The separation trajectories of the external stores are obtained through couple iterating between the solution of whole field and the solution of six-degrees-of-freedom equations.In this thesis, structured grid, chimera grid, Euler equations, 6DOF etc are used for aircraft/store separation research, the results of aircraft/store separation are in good agreement with AEDC's experaiments. These facts show that this numerical stimulant method is correct and reasonable.
