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.

Abstract: A protector for the leading edge of a rotor blade to provide enhanced erosion protection thereof. In an embodiment, the protector includes an energy absorption member attached to the rotor blade by a first adhesive bond layer and an erosion resistant member attached to the energy absorption member by a second adhesive bond layer. The erosion resistant member is operative to protect the leading edge of the rotor blade from erosion due to impacts from particulate matter, such as sand and rain. The energy absorption member is operative to absorb and disburse energy from impacts to the erosion protection member so that forces from the impacts are diminished or not transferred to the rotor blade. In another embodiment, the erosion resistant member is coated with a diamond film. As the diamond film is harder than sand, excellent resistance to wear from particulate matter and impacts rain is obtained.

Abstract: A protector for protecting aircraft, particularly helicopter rotor blades, from absorbing the sun's infrared rays and the accompanying heat build-up in order to keep adhesive material between spar connections from debonding and to avoid delamination from the rotor blade's composite skin. The rotor blade protector includes a cover configured to encircle the length of the rotor blade and a guide form for installing and removing the cover. The inner surface of the cover is coated, by vacuum deposition technology, with aluminum, titanium, or other metals or alloys. The coating thickness will be in the order of 9-30 billionths of a meter thick. A stripper rod is attached to the guide so that aircraft personnel can install and remove the protector from the helicopter rotor blade while standing on the ground. Optionally, a series of ribs can be provided along the cover to provide increased air insulation around the rotor blade.
