ABSTRACT:
An aircraft canopy fracturing system includes a canopy having fore and aft portions and a region that is severable from the canopy to provide an opening therethrough for the egress of aircraft occupants. The severable region has a shape that inhibits passage of the severable region through the opening created in the canopy once the severable region is freed from the canopy and is displaced aftward relative to the canopy. The canopy fracturing system also may include one or more mechanisms that will impart an aftward impulse to the severable region of the canopy once it has been severed and freed from the remainder of the canopy.
