A Relationship between Liquid Roll Moment and Liquid Side Moment

Abstract

Spinning projectiles carrying liquid payloads and performing large coning motion have uniformly been observed to experience rapid despin. For linear fluid mechanics, it has been shown that the ratio of the magnitudes of the liquid roll moment to the liquid side moment is the tangent of the coning angle. The validity of this relationship is demonstrated by gyroscope data obtained by M. C. Miller and flight data for twelve projectiles analyzed by R. L. Pope.
