Hail impact is an actual threat for aircraft structures that to fly through a hailstorm region cannot be avoided. In this paper, numerically evaluates the effect of indenter geometry on metal target plate. The six hail projectile (the angles of 40 °, 50°, 60 °, 70 °, 80 °, 90 °) with conical nose shape performed. The effect of sharp nose of conical 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 projectile entered the less significantly energy on metal target plate. The conical hail projectile with angles of °, ° showed the
highest and less contact force in hail impact event.
