ABSTRACT:
The aerodynamic body, such as an aircraft, includes a lengthwise extending fuselage and a pair of coplanar joined wings extending outwardly from opposed sides of the fuselage. The pair of coplanar joined wings are formed by at least two forward wings extending laterally outward and rearward from opposite sides of a forward portion of the fuselage, and at least two aft wings extending laterally outward and forward from opposite sides of a rearward portion of the fuselage. Each aft wing is joined to a respective forward wing at a common wingtip to thereby form one of the joined wings. In particular, the aft wing can either be joined to the outermost portion of the respective forward wing or to a medial portion of the respective forward wing such that a portion of the forward wing extends outboard of the common wingtip. In either embodiment, the forward and aft wings of the joined wing aircraft define respective planes which are mutually coplanar such that the resulting coplanar joined wing aircraft has enhanced aerodynamic and structural properties.
