| Abstract: | Some typical researches and primary characteristics of grid fins are introduced.Taking into account both calculation precision and efficiency,an Euler Equation Solver to analyze the aerodynamic characteristic of grid fins is adopted in order to obtain the control characteristic by comparing conventional planar wing with grid fin.The results illustrate that the method satisfies the need for primary aerodynamic configuration design. |
