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
