Abstract:

This paper deals with a single-degree-of-freedom motion of a rigid right circular cylinder, namely, rotation about any axis normal to the longitudinal axis. The two selected space orientations are such that in the first case the translational velocity vector and the longitudinal axis form the plane of rotation end-over-endmotion, and in the second case the longitudinal axis lies in the plane of rotation which is always perpendicular to the translational velocity vector. The aerodynamic static and damping stability of the cylinder are first derived for later use in the equations of motion for each of the above-mentioned cases. Rotation of the first type which may be coined in-plane rotation is non-linear in nature and depends upon the aerodynamic damping characteristics as well as the initial spin rate, while rotation of the second type coined normal rotation is linear and logarithmically damped.
