Artificial Icing Tests UH-1H Helicopter. Part 2. Heated Glass Windshield
Abstract
The United States Army Aviation Systems Test Activity conducted a limited evaluation of a heated glass UH-1H helicopter windshield from 3 January through 8 January 1974. The evaluation was performed at Edwards Air Force Base, California using the helicopter icing spray system and consisted of two productive flights for a total of 1.1 productive flight hours. One shortcoming was noted: restricted upward and downward forward field of view through the heated UH-1H windshield after exposure to an artificial icing environment. Within the scope of this test, the heated portion of the heated glass UH-1H windshield provides a satisfactory anti-ice/deice capability when flying in an icing environment. Further evaluation should be conducted to determine the optimum size, shape, and location of the heated portion of the windshield and to determine if electrical requirements for two windshields are compatible with UH-1H mission electrical loads.
