Correlation of Instantaneous Impact Drag Coefficients for Vertical Water Entry

摘要

A theoretical model for predicting the height of the heaved water surface about a cone during vertical water entry was developed. The successful comparison of the predictions of the theoretical model with experimental data encouraged an extension of the model to include a method for predicting the impact drag force during vertical water entry. Experimental data for cones, ogives, cusps and sphere were successfully correlated indicating the usefulness of the model for correlating impact drag forces for a wide range of configurations.
