Development of Design, Test, and Acceptance Criteria for Army Helicopter Transparent Enclosures

Abstract

Results are presented of an effort to develop improved design, test, and acceptance criteria for all rotary wing aircraft transparent structures. Some of the criteria relate to all-weather capability, optical and structural quality, abrasion resistance, safety, and bird and ballistic resistance. The transparent structures, specifically windshields, made of the present glass laminate and 1/4 inch stretched acrylic do not have a strike resistance beyond 100 mph, when exposed to bird impact tests, whereas the use of polycarbonate achieves a resistance at a speed of at least 211 mph.
