Structural and aerodynamic considerations for an oblique all-wing aircraft

Abstract

A key design issue for the Oblique All-Wing aircraft is the packaging of the payload compartment, the fuel tanks, and the other internal components within the airfoil. The internal arrangement of such vehicles is strongly coupled to the exterior vehicle geometry. For example, the height requirements of a passenger cabin directly influence the aircraft thickness and span. As a result, the internal arrangement strongly affects aerodynamic performance and structural weight. Configuration criteria are defined and/or discussed, and a baseline aircraft is developed. Also, some of the major tradeoffs that affect structural weight and aerodynamic performance are presented.
