Failure Mechanisms in Aircrew Helmet Visors.

Abstract

The causes for removing aircrew helmet visors from service were investigated as part of the Armstrong Laboratory's Advanced Aircrew Vision Protection (AAVP) program. The reason for the investigation was to identify better technologies, specifications, or procedures that could be applied to the aircrew laser eye protection (ALEP) visors being transitioned under the AAVP program. Clear and neutral gray (sun) visors that were identified to be discarded were requested and received from four Air Force life support units. Fifty-three (53) visors, 44 sun and 9 clear, were received and examined. The procedures used and the results of this study are presented here. The single cause of visor degradation that resulted in removing it from service was found to be damage to the surface hard coating, primarily scratches.
