Abstract: A despinning mechanism for a shaped charge warhead carried by a spinning projectile is shown to comprise a weight attached to a cord wrapped around such warhead and a release mechanism operative to allow the weight and cord to move radially outwardly from such warhead to impart a decelerating torque on such warhead.

Abstract: A pedestal and gimbal assembly related to missile semi-active radar seekers or supporting three gyroscopes and functions as a reference platform to relate airframe attitude. This is mechanized by utilizing the two degrees of freedom gimbal for pitch and yaw and controlling the missile body roll axis for the third degree of freedom. Structure of the positioning system includes a pedestal having an inner gimbal assembly including a support for mounting the antenna assembly and the gyros. A yaw torque motor assembly is carried by the inner gimbal and is provided with a pair of output shafts for supporting the inner gimbal and controlling the yaw movement thereof. A pitch motor is housed in the pedestal and includes a drive pinion and a drive shaft. The drive pinion is connected to the drive shaft. The drive pinion and yaw motor operates to control the pitch movement of the antenna assembly.

Abstract: An adaptive actuator system comprising a rotatable shaft operatively coupled to a torque biasing means for biasing the rotational direction of the shaft, and also operatively coupled to a counter torque developing means for sensing the rotational bias of the shaft and providing a counter torque proportional to the rotational bias.
