Abstract:
The width to width rat io of grid fin was an important parameter influencing the aerodynamics of grid fins. In order to research the aerodynamic characteristics of grid fins effected by width to length ratio, the grid fins of three hight to width ratios were adapted in wind tunnel experiments at subsonic, transonic and supersonic speeds. The results show that the drag of grid f ins is little affected by width to chord rat io, the normal force of grid fins was large, and that the smaller was the ratio, the better was the characterist ics of the grid fins. s normal force in tested sizes of width to chord ratios.
