Grid fins is a new kind of wing more advantageous than traditional wing, but the drag of grid fins is its main drawback. Early research has shown that the swept grid fins can reduce resistance effectively. In this paper, numerical simulation, was studied based on different swept form of grid fins. The numerical results show that at supersonic speed stage, the model of forward-swept sharping can effectively decrease the resistance. As to the lift, in different Mach range, forward-swept, forward-swept sharping and the whole-swept have good lift characteristics; In general, the forward-swept sharping has the largest lift-to-drag ratio, showing the best aerodynamic characteristics.
Key words： grid fins; forward-swept; sharping; aerodynamic characteristics
