The Application of Thermal Sealing to Aircrewman's Inflatable Protective Equipment.
Abstract
A program was undertaken to develop material research and thermal sealing methods to improve the overall characteristics of aircrew inflatable protective equipment, making use of impermeable coated fabrics. Anti-exposure suits, anti-exposure mittens and hood, anti-G coveralls, life preservers and life rafts, are now assembled using neoprene-coated nylon and a cold cementing procedure; this method of construction, however, requires many hours of labor and results in excessive stiffness and bulk in the finished item. Polyurethane-coated nylon fabric of various weights, construction, and coatings were investigated, as well as dielectric and ultrasonic thermal sealing techniques, equipment, and final assembly criteria with the ultimate goals being: weight reduction without sacrifice of seam strength, increased comfort in personally worn items, production cost reduction, and improved reliability.
