Metal wings are adopted to provide drag force and rotating torque fornon-parachute terminal sensitive projectile (TSP). The wings are usually quite thin toadjust the demand for diameter of warhead. It’s conventional to simulate theaerodynamic characteristics by considering wings of TSP as rigid ones. Affected byaerodynamic force, thin metal wings could deflect during the TSP’s falling process,which could affect its aerodynamic characteristics. Therefore it’s more accurate totake wings as elastic body. The wing structure is defined by three parametersincluding bending angle, bending ratio and length-width ratio. The S-S typenon-parachute TSP has two wings which make four bending angles, four bendingratios and two length-width ratios. Based on ANSYS software, this paper analyzeseffect of wings structure parameters on aerodynamic characteristics of TSP.
