A systems analysis of a new restraint systems for troop restraint systems in helicopters was conducted. Hardware was designed and statically tested in accordance with the requirements of two proposed specifications. Design iterations were required on some hardware components, and three designs to be dynamically tested were developed. Dynamic testing of the restraint systems revealed additional weaknesses, design modifications were incorporated, and testing was reconducted until satisfactory results were obtained. The proposed specifications were modified and refined in accordance with the test results, with the net effect that the two specifications as they now stand define advanced restraint systems providing optimum restraint for occupants of Army aircraft which can be built within existing state of the art, are low in weight, and have reasonable cost.
