Free surface breakdown in a rapidly rotating liquid payload
Abstract
The liquid payload in a cylindrical cavity in a spin stabilized projectile can support inertial waves. If the liquid only partially fills the cavity, the free surface wave form of these waves can be viewed stroboscopically. It is seen that, periodically, the free surface wave form breaks down, only to reappear. It is shown that this phenomenon is due to the interaction between inertial and capillary waves, and that this interaction may explain the spurious dynamic stability effects one sometimes observes in the flight of spin stabilized, liquid payload projectiles.
