A tri-service test program (U.S. Army, Air Force, Marines) was conducted to evaluate recent technology developments in scratch-resistant coatings for helicopter transparencies. Eight coatings were evaluated for application to polycarbonate and stretched acrylic flat panel coupons. Two metallic coatings, ITO and gold, were also evaluated in conjunction with the abrasion-resistant coatings. A series of mechanical, environmental, and optical coupon tests were conducted on the coated and uncoated baseline configurations. Mechanical testing included three-point flexure and tensile properties. Environmental testing included fluid soak, humidity conditioning, sand and dust, and weatherometer. Optical testing included Bayer abrasion, haze, and light transmittance. Two of the more promising coatings were incorporated in a fight test evaluation at the Naval Weapons Center, China Lake, CA. The forward right gunner's windows on two AH-1W SuperCobra gunships were modified with the scratch-resistant coating. Results to data show excellent scratch resistance and durability.
