Experimental investigation of dynamic motions of an internal part in an artillery projectile

A Partially Restrained Internal Member (PRIM) in a particular developmental artillery projectile does not, seemingly, effect its flight performance. However present theory predicts that the PRIM should cause a reduction in spin and growth in yaw resulting in significant range loss. The gyroscope experiments described in this paper produced PRIM motions which are periodic in precession as well as nutation. These periodicities and their slow growth have not been previously addressed. A more complete theory of motion is needed to describe the dynamics of PRIM motion.
