An aircraft including a single fuselage having a main wing and a horizontal stabilizer airfoil pivotally attached at their centers to the fuselage. The pivotal attachments allow the airfoils to be yawed relative to the fuselage for high speed flight, and to be positioned at right angles with respect to the fuselage during take-off, landing, and low speed flight. The main wing and the horizontal stabilizer are upwardly curved from their center pivotal connections towards their ends to form curvilinear dihedrals.
An aircraft having variable airframe geometry for accommodating efficient flight at subsonic, transonic, and supersonic speeds, comprising: a wing having an approximately elliptic planform, and a curvilinear dihedral formed by the lateral extremities of said wing being curved upwardly from the midspan so as to obtain a substantially elliptical lift coefficient distribution along its length; a single elongated fuselage pivotally connected to said wing; means for rotating said wing relative to said fuselage such that in the transonic and supersonic speed r...
