Oblique-wing twin- and single-fuselage transonic transport models were wind tunnel tested and showed superior aerodynamic efficiency to that of fixed-swept-wing, variable-sweep-wing, and delta-wing configurations similarly tested. The oblique-wing airplane had the smallest gross weight and lowest fuel consumption; it could achieve lower noise levels than swept- and delta-wing aircraft by engine-nacelle treatment; and it was aeroelastically less stable than a sweptback wing but more stable than a swept-forward wing. Graphite-epoxy met stability requirements without additional stiffening, whereas aluminum needed some additional stiffness. Further studies are called for to develop the full potential of the oblique-wing concept.
