An aircraft having a fuselage and a pair of forward-swept wings includes a wing carry through extending transversely through the fuselage joining the wings together to form a unitary wing structure, two hinge assemblies, each located adjacent a different one of the wings for rotatably mounting the wing structure to the fuselage and located forwardly of the wing carry through and on a spanwise axis intersecting the aerodynamic centers of the wings, and two actuators, each located rearwardly of the hinge assemblies and extending between the fuselage and a different one of the wings for selectively rotating the wing structure about the hinge assemblies. The hinge assemblies attach the wing structure to the fuselage such that the axis of rotation of the wing structure is substantially collinear with the axis intersecting the aerodynamic centers of the wings so that relatively little force is required of the actuators to vary the angle of incidence of the wing structure.

In an aircraft of the type having a fuselage, a pair of forward-swept wings, and a wing carry through extending transversely through said fuselage and outwardly therefrom to form an integral part of each of said wings thereby joining said wings together so as to form with said wings a unitary wing structure, the improvement comprising: at least two hinge means, each located forwardly of said wing carry through adjacent a different one of said wings and interconnecting said fuselage and said wing carry through, for rotatably mounting said unitary wing structure via its wing carry through to said fuselage, each of said hinge means also being located on a spanwise axis intersecting aerodynamic centers of each of said wings such that an axis of rotation of said unitary wing structure defined by said hinge means is substantially collinear with said spanwise axis; and means attached to said fuselage rearwardly of said unitary wing structure, and extending between and interconnecting said fuselage and said wing structure, for selectively rotating said wing structure about said axis of rotation to vary the angle of incidence of said wing structure as a unit and therewith said wings with respect to said fuselage but without varying the angle of forward sweep of said wings with respect to said fuselage.
