Water-entry of a torpedo is a case which involves large impact forces. These loads on the shell of the torpedo upon impact often result in damage to the torpedo’s structure and internal components. These loads, through experimental observations, have been seen to reach magnitudes as high as 105 Newtons and vary with the velocity of penetration and the incident angle on the water surface. Hence, estimating the shock encountered by the torpedo as a function of its velocity as well as its orientation of impact and understanding the structural behaviour of the shell is therefore paramount to ensure reliability and success.
