Escape System Requirements for U. S. Army Aircraft in Vietnam 670575

U. S. Army fixed wing aircraft employed in R. V. N. at the present time range in sophistication from the 0–1, “Bird Dog”, a single engine, two place light aircraft, to the OV-1, “Mohawk”, twin engine, two place turbo-prop aircraft. Each aircraft has unique escape problems and employs different methods that are appropriate to meet the requirement.
U. S. Army rotary wing aircraft in R. V. N. range in sophistication from the OH-13, “Sioux”, to the CH-47A, “Chinook”. All rotary wing aircraft present a formidable escape system design problem. Attempts to design such a system have been made, but none have become available for operational use. Therefore, no single escape system operation at the present time is appropriate for all Army aircraft.
Current practice prohibits the employment of an escape system for crew members that is not available for passengers in Army aircraft, for example, the aeromedical evacuation aircraft.
Current escape systems designed to safely land the cabin area of the aircraft to the ground by parachutes are not available for the larger Army aircraft, or are too heavy for the smaller Army aircraft.
Therefore, there is a continuing requirement for the developement of a single type system compatible with all Army aircraft.
