Abstract
Rocket Accuracy Improvement Device, when coupled between the warhead and motor of a typical free flight rocket, isolates the warhead from the rocket motor in the axis using a plurality of ball bearings and thereby enables the warhead to spin independently of the motor. The separation of the warhead from the motor allows the angular momentum of the warhead, which has reached its maximum spin rate by the time the motor burns out, to act gyroscopically to maintain the trajectory of the rocket even when the motor reverses its spin, thus achieving a much more predictable flight path for the rocket.
