Abstract
A frangible access panel separation system for separating an access panel from a host structure is disclosed. In one embodiment, the system includes first and second doublers for initially interconnecting the first and second sections, an expandable explosive system contained in a cavity defined by the first and second doublers and first and second sections, and first and second staggered grooves positioned on the first and second doublers, the first and second doublers severable along break planes defined by the first and second staggered grooves to facilitate a substantially collision-free separation and ejection of the first section relative to the second section, and a detonator member for initiating detonation thereof.
