A fin deployment system for missiles and munitions that deploys and activates straight flat fins for roll control authority. The fin deployment system employs numerous design features, among which are the following: A wrap-around fin concept generates space-savings within a projectile body whereby the fins are arranged in a wrapped configuration around a boomtail structure. The fins may be constructed of a super-elastic material; the system eliminates mechanical means of deploying the wrapped fins, eliminating the need for springs to deploy the fins. The...
1. A fin deployment system for attachment to a projectile having a main axis, comprising:a plurality of fins;a plurality of hinges attached to an aft section of the projectile to rotate the fins from a stowed position to a deployed position after the projectile is launched;a retention cover attached to the aft section of the projectile to cover and retain the fins while the projectile is in storage and before the projectile is launched, further comprising a fin cover that provides retention of the fins while in the stowed position, and wherein the fin co...
