Abstract:

A review was conducted for the coning anomaly of the PAM vehicles. The focus was on the nutational flows inside spinning cylinders, fully or partially filled, with or without exit thesis, a rather abrupt transition from a forced vortex motion to a free vortex motion occurs inside the spinning solid rocket motor at Ro 0.6-0.8. The vortex after transition supports helical waves. As the helical waves travel along the vortex, the precess in the resonant interaction with the PAM vehicle and the subsequent coning growth.
