A Study of the Water-Entry Cavity

Description: Report describing a study of missiles producing clean cavities after water entry the cavity development. These are shown by theory to depend significantly only on: entry angle, an effective mass, and a Froude number based on the nose-flat diameter. A method is outlined for estimating pressures in closed, almost-steady cavities, from cavity geometry. Data from application of these methods to water-entry records of models are given. (Abstract)
