Transmittance Characteristics of U.S. Army Rotary-Wing Aircraft Transparencies.

Abstract

This report documents a survey of the spectral and luminous transmittance characteristics of transparencies (windscreens) used in currently fielded U.S. Army rotary-wing aircraft. The survey was conducted in two phases. In the first phase, samples of windscreens from each aircraft type were evaluated in the laboratory for phototopic (day) and scotopic (night) luminous transmittance. The spectral transmittance of each sample also was measured. Based on laboratory measurements of unused samples, all windscreens met specifications. However, field measurements on windscreens showed consistent failure of luminous transmittance requirements. This loss of transmittance is attributed to haze resulting from exposure to environmental factors. (MM)
