A Computer Program for Modeling Water Entry Cavity Performance and Comparisons of Predicted with Observed Cavities

Abstract

A computer program is presented which is capable of modelling the geometry and performance of the water entry cavity produced by the entry of axially symmetric projectiles. The program is based on an existing theoretical cavity flow model modified to account for atmospheric surface pressure. The computer model is shown to satisfactorily predict cavities produced by vertical and oblique entries (including high-speed entries) from normal air of right circular cylinders and truncated ogives.
