The spin rate of a rocket missile is controlled by bevelling the inside of he leading edge of the missile fins. Altering the bevel angle controls the rate of spin. The spin rate is also controlled by sweeping back the leading edges of the fins.

Method of controlling the spin rate of tube launched rockets

This invention comprises wrap-around fins for a rocket missile, the fins ng mounted on rods which are borne by a spool-like runner which encircles the nozzle body of a rocket missile. The nozzle body is exteriorly coated with teflon. The spool-like member has a ring-shaped extension on each end, each of which fits into a ring-shaped teflon bearing which, in turn, fits into a slot in a flange on the nozzle body whereby the spool-like member and the fins which are mounted on it are free to rotate relative to the nozzle (and therefore the rocket) body. The interior of the nozzle of the rocket is formed with flutes, the action of the exiting gases on the flutes causing the missile body to rotate in flight.
