Helicopters generally have stretched-acrylic windshields which are said to scratch easily in service due to wiper operation or impingement of sand or stones. Operation of the wiper without the use of a lubricant (such as water) is particularly damaging. Also, while in flight, any impingement of such objects as birds or bullets may result in catastrophic failure. The object of this search is to make a literature survey, and to contact several leading commercial manufacturers in order to obtain current information on abrasion-resistant windshields.
