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.

not available for EP0796197Abstract of corresponding document: WO9619381A hood detonation system for blasting two hoods in a two-seated aircraft is described. It comprises a first detonation cord (3) detonable by means of initiation and attached to the first, front hood (1), and a second detonation cord (4) detonable by means of initiation and attached to the second, rear hood (2). The hood detonation system is in particular characterized by a protective balloon (19) inflatable by initiation of a gas generator essentially simultaneously with the initiation of the detonation of the second detonation cord (4), and adapted to prevent splintered parts from the second hood (2) to move into the space inside the second hood.
