Prediction of Vertical Water-Entry Forces on Ogives from Cone Data

Abstract

An empirical method of predicting the drag coefficient for vertical water entry of pointed shapes is presented. The drag coefficient versus depth function is generated from experimental results of the vertical entry of cones of various angles. Comparison with experimental results shows that the predicted values are accurate to within + or - 25 percent. A computer program for predicting the water-entry drag coefficient of many shapes is included.
