Abstract
A fold-out fin has a fin geometry defined by two cross-sectional cuts through the cylindrical projectile body, both cuts being parallel to the boattail surface. This geometry insures that the stowed fin assembly fits within the gun tube. This geometry also exhibits low drag and good aerodynamic behavior. Upon launch, the fins are deployed and then locked in the fully open position with a spring loaded pin.
