PERSONNEL RESTRAINT SYSTEMS STUDY, UH-1A AND UH-1B BELL IROQUOIS HELICOPTERS
Abstract
Detailed recommendations for the improvement of the personnel restraint system in the U. S. Army UH-1A and UH-1B aircraft are presented. The recommendations pertain primarily to strengthening the existing restraint system components. The modifications proposed indicate the following strength improvements: (1) Cockpit - The crew's restraint system is increased from a 10-12G value to a 20-25G value; (2) Troop Compartment - The troops' lap belt attachments are increased from a 12-15G value to a 22-25G value. The above strength increases can be achieved with a weight increase of 7 pounds per aircraft and a cost of approximately $70 per aircraft. The following information is included in this report and the Supplement: (1) Engineering - strength analysis of proposed modifications; (2) Parts Procurement - detailed engineering drawings with a bill of materials from which retrofit kits can be procured; (3) Parts Manufacture - drawings necessary for the manufacture of retrofit kits; (4) Retrofit Kit Installation - sufficient drawings for installation of the retrofit kits by Army personnel; and (5) Administrative - a cost and weight summary of proposed modifications.
