A water-activated canopy release mechanism having a detachable sleeve positioned between the arms of a buckle yoke. The sleeve contains a longitudinal passage having a release piston and bushing positioned therein and supporting the sleeve within the yoke. An explosive cartridge mounted at the piston end is fired by a sensor activated by water of predetermined conductivity and drives the release piston completely into the sleeve and wedges it there, thus freeing the end of the sleeve adjacent the cartridge. Simultaneously, the piston drives the bushing out of the other end of the sleeve and against a wedge carried by the yoke arm. As a result, both the piston and the bushing are held in a position which permits the sleeve to drop free of the yoke releasing the canopy from its load. |
