A Study on Aerodynamic Characteristics of Damaged Cruise Missile

Wind tunnel tests were performed on damaged Tomahawk multipurpose cruise missile to get aerodynamic characteristics parameters under the conditions of the different Mach number,attack angle and side slip angle.The effect rules of bend angle of the wing on lateral force coefficient,yawing moment coefficient,lift force coefficient and frontal drag coefficient were obtained.The results show that lateral force coefficient and yawing moment coefficient increase linearly with the bend angle of the wing,and the higher flight Mach number,the more notablely the effect becomes.Lift force coefficient,frontal drag coefficient,rolling moment coefficient and pitching moment coefficient aren't affected significantly.
