Abstract:

This report contains a comprehensive compilation of test data and analytical techniques for predicting the behavior of vehicles during water entry and during the cavity-running phase. It contains data to predict the water impact forces on nose shapes such as disks, cones, ogives, spheres, cusps, disk ogives, etc. during vertical and oblique water entry. Cavity development phenomena are discussed and approximate ways of predicting cavity size and shape are presented. Stability characteristics during the early running phase are also discussed. In general, the report is intended to provide the necessary data for the design of water-entry ordnance.
