Based on static force measurement, the experiment of a canard missile with three wrap around fins was carried out in the CG-01 wind tunnel in order to study on the aerodynamic characteristics of rolling missile under different roll angle. The wind tunnel experimental results were gained at 0.4~2.0 Mach number, 0°~10° angle of attack and 0°~315° angle of roll. The experimental results indicate that the aerodynamic characteristics of canard missile with three wrap around fins exist a certain difference at different roll angle. The roll angle has slight influence on aerodynamic characteristics at low angle of attack, but when the angle of attack increases, the lift coefficient, drag coefficient, pitching moment coefficient and rolling moment coefficient all begin to fluctuate with the roll angle change, and the fluctuation amplitude of aerodynamic coefficients gradually increase with the angle of attack increase.
