ABSTRACT:
A transparent laminated structure having multiple peel-away laminated film layers for protecting windscreens, particularly windscreens of rotary aircraft, from environmental conditions. The laminated structure includes at least one laminated layer wherein each layer includes a film, a bonding layer on a first major side of the film for releaseably attaching the film to either the windscreen or to an adjacent laminated film layer, a conductive material on a second major side of the film for dissipating electrostatic charging in the laminated structure that may occur due to accumulated precipitation static during aircraft fight, and a hard coat layer for protecting the relatively softer film against abrasion. As the outermost film layer becomes degraded below acceptable levels, that film may be easily removed, exposing a subsequent unblemished film layer.
