A PRELIMINARY STUDY OF THE MECHANISM OF WATER-ENTRY WHIP OF 20-DEGREE CONE NOSED MODELS

Abstract

Preliminary experimental data are reported on the whip behavior of 20-degree cone nosed models with variable center of gravity and variable transverse moment of inertia launched at 45 degrees and at 105-135 feet per second. The results are compared with fundamental ideas and it is concluded that there is a high sensitivity of whip to initial pitch and that there may be a force distribution on the nose producing the effect of a couple during nose penetration.
