The spinning plug nozzles (SPN) has a direct effect on the flow of the rocket exhaust gases. It acts like a gyroscope to restore the angle between the rocket axis and the spinning plug axis to zero. Thus, when the rocket body axis becomes misaligned with the plug axis, due to external moments acting upon the rocket, leading to inaccuracy, the SPN restores the alignment and minimizes the flight path error. In 1980, Battelle's Columbus Division completed a contract for Lockheed Missile and Space Company on the military application of the SPN. Battelle developed its SPIN (Spinning Plug In Nozzle) model to help evaluate the concept. The software was first applied to three different rocket types: the 2.75-in., the Multiple Launch Rocket System (MLRS), and the OATS. This paper summarizes this work at Battelle.
