A Systems Analysis of Alternative Concepts for Aircrew Cold Weather Clothing
Abstract
This analysis was performed in support of a requirement to develop a new clothing system for Army aircrews operating in regions where minimum winter temperatures are between 0 F (-17.8 C) and -60 F (-51.1 C). Each of five proposed clothing system concepts was evaluated to determine its feasibility and its effectiveness in satisfying the essential requirements specified in the Letter of Agreement. Two analytical models which simulate body cooling for various metabolic and environmental assumptions were used to determine the clothing insulation (clo) values required to provide thermal protection. Since the results indicated that auxiliary heated clothing items especially for the hands and feet will be necessary, an evaluation of potential power sources is included in the study. The report recommends that either two ensembles or a basic and an augmented version of the same ensemble be designed. The basic system will be worn in cold and intermediate cold regions and should be designed using state-of-the-art technology to protect to -15 F (-26.1 C). The other ensemble will be worn in extreme cold climates where temperatures can fall to - 60 F (-51.1 C).
