superiority reflected in grid fins compared traditional flat wing, it is necessary to study their aerodynamic characteristics. The cross-section shape for grid important geometric parameter, numerical simulation method aerodynamic analysis of different cross-sectional shape. The results showrid fins with cross-sections as diamond, square, hexagonal can greatly reduce resistance compared with the rectangle bluff cross-section ones. At the same time, they also increase the lift and lift-drag ratio to some extent. Among the grid fins streamlined cross-section, dynamic performance.
Key words： grid fin; cross-section shape; grid fin wall; aerodynamic characteristics
