Deployable overhead protection assembly and methods of use for canopy fragilization system

A canopy fragilization system for use in an aircraft ejection system, the canopy fragilization system comprising:

• a sharp breaker disposed on a first side of an ejection seat, the sharp breaker configured to act as a primary breaker of a canopy of an aircraft;
• a blunt breaker disposed on a second side of the ejection seat, the blunt breaker configured to act as a secondary breaker of the canopy of the aircraft;
• and
• a deployable overhead protection assembly comprising a first tertiary breaker and a second tertiary breaker.

A method for fragilizing a canopy of an aircraft during an ejection event, the method comprising:

• exerting a first impulse on the canopy of an aircraft with a sharp breaker;
• exerting a second impulse on the canopy of the aircraft with a blunt breaker;
• exerting a third impulse on the canopy with a first tertiary breaker disposed forward of the sharp breaker and the blunt breaker;
• and
• exerting a fourth impulse on the canopy with a second tertiary breaker disposed forward of the sharp breaker and the blunt breaker.
