Numerical Investigation of Nose Sharp Changes in Ice Projectile with Conical Shape

Hail impact is an actual threat for aircraft structures that to fly through a hailstorm region cannot beavoided. In this paper, numerically evaluates the effect of indenter geometry on metal target plate. The six hailprojectile (the angles of 40°, 50°, 60°, 70°, 80°, 90°) with conical nose shape performed. The effect of sharp nose ofconical hail projectile investigated on metal target plate behaviors like impact force, kinetic energy and internal energy.The results showed that the sharpness nose of conical hail projectile reported the highest wasted energy. This projectileentered the less significantly energy on metal target plate. The conical hail projectile with angles of 60°, 80° showed thehighest and less contact force in hail impact event.
