THE EFFECT OF SLOW SPIN ON THE UNDERWATER TRAJECTORY OF A MISSILE SINKING AT TERMINAL SPEED,

Abstract

The motion of a stable, slowly spinning underwater missile sinking at terminal speed is examined. It is assumed that some parts of the missile are out of alignment due to imperfect manufacture or damage at water entry. It is shown that the trajectory is a circular helix with its axis vertical. The diameter of this helix is determined by the characteristics of the missile and the degree of misalignment present, and is a rapidly decreasing function of the spin. (Author)
