Liquid payload roll moment induced by a spinning and coning projectile
Abstract
The linear theory for a coning and spinning liquid payload has been extended to the calculation of a quadratic roll moment. The resulting quadratic roll moment coefficient is shown to be exactly the negative of the linear side moment coefficient for constant amplitude coning motion. This relationship between side moment and roll moment has been observed for projectiles with moving solid components and has encouraging experimental support for liquid payloads.
