Keywords: superhigh capacity passenger airplanes, flying-wing configuration

Late in the 1980s TsAGI began investigating superhigh capacity passenger airplanes of a flying-wing configuration. The idea of this concept lies in the possibility of accommodating passengers in the central part of the wing or in the central part of the wing and the fuselage of a lower size than of conventional layouts. In this case it is possible to realize significantly higher L/D ratios, reduce the takeoff weight, improve fuel and economic efficiency. Since the end of 1997 TsAGI has been carrying out the activity under Project 548-97 of the ISTC «Investigations of Technologies Critical for Implementing an Airplane of Flying-Wing Type with Superhigh Seating Capacity». Computations have shown that the FW configuration, while meeting the requirements similar to those for the B747-400, the largest airplane now in service, can have fuel efficiency by 35% higher and DOC by 22% lower. The investigations are being continued in the direction of aerodynamic experiments and more sophisticated analysis of
