This article introduces the experime ntal investigations of aerodynamic characteristics for the bodies with grid fins in supersonic speeds. It discusses the aerodynamic characteristics of grid fins through analyzing the aerodynamic experimental results for the bodies of two gr id fin configurations and comparing them with that for the body of planar fins. The results indicate that (1) the drag force of grid fins is greater than that o f planar fins, (2) the more quantitins of grid is, the more drag force is, (3) t heir difference of lift force is small at mach number 2.0096, the lift force of grid fin is greater than that of planar fin at mach number 2.521, (4) the drag f orce levels are decreased considerably through shaping the frame cross-section of grid fin.
