Abstract : A family of rotorcraft were defined to meet the projected requirements of the U.S. Army for combat airlift in the year 2000 and beyond. A detailed definition of equipment and mission load inventories was developed, and a knowledge-based simulation assessed the capability of various-size aircraft to transport these inventories in three combat theaters: Europe, Southwest Asia, and Latin America. Payload capabilities of 18, 26, 30, and 39 thousand lb (8,165, 11,793, 13,608, 17,690 kg) with 270 nm (500 km) radius of action at Army hot day ambients were identified as potentially cost effective design points. A 9 X 9 ft (2.74 X 2.74 m) cabin cross section was required, with a cabin length of 32 to 41 ft(9.75 to 12.5 m) depending on design payload. Single and tandem rotor helicopter solutions were defined for each of the four design payloads. A tilt rotor solution was also examined. A single roto configuration with a design gross weight of 94,000 lb (42,637kg), a rotor diameter of 122 ft (37.2m), and three engines served as a baseline for evaluation of the impact of various design criteria and system technology levels.
