ABSTRACT:
A two stage remotely actuated structural latch especially suitable for supporting an aircraft canopy during flight as well as on the ground. One single part of the latch carries all of the load and the latch can be locked or unlocked from a remote location by use of a rod, cable or tube to acruate only non-structurally loaded pins and links which have high mechanical advantage in the first stage unlocking movement. This arrangement permits emergency canopy release during flight by the application of average human leverage and provides maximum pull up capability at the time of maximum mechanical advantage. A self-aligning and floating hook pin concept eliminates the need for hook and mating pin alignment.
