Abstract
A fin lock assemblyfor locking and unlocking missile finsincludes a pistonmovable along a piston axisbetween a locked position for preventing a fin from rotating and an unlocked position for allowing the fin to rotate. The fin lock assembly includes a camshaftrotatable between a locked position and a relatively-rotated unlocked position about a cam axisthat is transverse the piston axis. The camshaft has an eccentric portionconnected to the piston such that rotation of the camshaft between the locked position and the unlocked position moves the piston between its corresponding locked and unlocked positions. The fin lock assembly includes a torsion springconnected to the camshaft to bias the camshaft toward its unlocked position. A latch mechanismholds a plurality of camshafts in their locked positions and simultaneously releases the camshafts to release their fins.
