Foamed-in-Place Helmet

Abstract

The HGU 2A/P helmet was unsatisfactory because of discomfort, lack of retention during ejections, and restricted upward visibility. The Foamed-in- Place helmet process evaluated in this OT&E was an attempt to correct the deficiencies that existed in the former helmet. Life support technicians are capable, with practice, of local fabrication of acceptable Foamed-In- Place helmets. Most of the material and equipment provided were satisfactory; however, some were unacceptable and considerable supplies were required that were not provided. Instructions for the helmet liner forming process, issued by Aeronautical Systems Division, were found to be adequate. The instructions should be refined and photographs and illustrations should be added. Instructions for the helmet fabrication were inadequate. Participating aircrews rated the test helmet superior to the previously used helmets in the areas of comfort (82 percent) and stability (80 percent). No significant difference was noted in restrictions to visibility. Noise attenuation was rated acceptable. (Author, modified-PL)
