The initial cavity, ballistic trajectory and velocity attenuation of the sphere pellets are similar at different water-entry angles and initial velocities.
Based on the unsteady potential flow theory of incompressible liquid, a model of water-entry impact force for air-launched mine was presented, and the water-entry impact force was calculated.
