Development of a Backup Cover for the AH-1 Canopy Removal System

Abstract

This development program was funded to develop and test a backup cover for the Window Cutting Assemblies of the AH-1 Canopy Removal System. The purpose of the backup cover is to extend the service life of a Window Cutting Assembly which has developed a crack in the polycarbonate retainer. The function of the backup cover (or shell) is to aid the damaged retainer in directing explosive energy and fragments from a Window Cutting Assembly outboard away from the crewmen. This report defines the design of the backup cover, the testing performed to substantiate the design and documents the successful completion of this testing. The testing included twenty-one (21) subscale tests to verify the environmental capability of the shell design and two (2) full-scale canopy removal tests of the right side of the airframe from a simulated crash attitude.
