ABSTRACT:
A release mechanism adapted for coupling parachute canopy riser straps to parachute harnesses is described wherein the male and female members of the mechanism are held together by two axially aligned bolt elements (a broken bolt) disposed in a common coupling passageway defined through the male and female members. An integral electronic water-activated energizing mechanism drives the two element broken-bolt longitudinally in the coupling passageway allowing the male and female members of the mechanism to separate whereby one of the bolt elements stays with the female member and the other bolt element stays with the male member. The described release mechanism further includes protective cover means for isolating sensing electrodes of the electronic water-activated energizing mechanism from the external environment prior to deployment of the parachute canopy.
