Abstract
A parachute release mechanism is provided which is compact, lightweight, and free from external wire harnesses. The release mechanism includes a passage connected between a source of pressurized gas and a piston chamber having a piston disposed therein. A shear pin is disposed in an opening in the piston and in the piston chamber. Activation of the source of pressurized gas causes the piston to move forward shearing the shear pin and either deploying or releasing a parachute.
