Abstract:

An experimental investigation of the vertical water-entry deceleration of various cone nose shapes, and a data-reduction method for the resulting information are described. Total drag coefficient, and added mass coefficient are determined as functions of penetration distance. These functions are shown to be independent of entry velocity and model mass over a wide range of test conditions. A method of predicting the accelerations experienced by the vertical water entry of an arbitrary cone is described.
