TLDR
In this article, a roll damping apparatus for a spinning projectile having a first section and a second section rotatably attached about a roll axis is described. But this is not applicable to our case.
Abstract
The invention relates generally to a roll damping apparatus for a spinning projectile having a first section and a second section rotatably attached about a roll axis. The roll damping apparatus comprises a first portion attached to the front section, and a second portion attached to the rear section. The first portion is adapted to cause a braking frictional force to act on the second portion, the braking force being effective to control the spin rate of the front section relative to the rear section. The invention further relates to a spinning projectile having a roll damping apparatus.

Steerable rotating projectile

TL;DR: In this article, a method for controlling a flying projectile which rotates during flight, comprising: determining an angle of rotation of an inertial mass spinning about an axis during flight; and controlling at least one actuator for altering at least a portion of an aerodynamic structure, selectively in dependence on the determined angle and a control input, to control aerodynamic forces during flight.

Method and apparatus for radial thrust trajectory correction of a ballistic projectile

James Linick
TL;DR: In this article, a system for controlling the placement of a gun launched projectile adapted with a radial impulse motor incorporated into the projectile for imparting a thrust subsequent to launching and a receiver incorporated into a projectile for targeting information for determining the projectile trajectory and the projectile roll rate, roll position, and pitch, i.e., vertical reference.
