Abstract
A canopy for an aircraft includes a transparent cover, and a severance cord coupled to the transparent cover. The severance cord includes a fragmenting pattern including a plurality of outer perimeter segments that define an outer perimeter of the fragmenting pattern, and a plurality of inner fragmenting segments that are inside the outer perimeter. The fragmenting pattern is configured to break the transparent cover into numerous fragments when the severance cord is detonated.
Claims22
A canopy for an aircraft, the canopy comprising:
- a transparent cover;
- and
- a severance cord coupled to the transparent cover,
