From Special Relativity to Feynman Diagrams

Abstract

This report contains a comprehensiv compilation of test data and analyticaltechniques for predicting the behavior of vehicle during water entryand during the cavity-running phase. It contains data to predictthe water impact forces on nose shapes such as disks, cones, ogives,spheres, cusps, disk ogives, etc. during vertical and oblique waterentry. Cavity development phenomena are discussed and approximateways of predicting during the early running phase are also discussed.In general, the report is intended to provide the necessary datafor the design of water-entry ordnance.
