1. An aircraft having variable airframe geometry for accommodating efficient flight at low speeds and as speed increases towards supersonic speeds, the aircraft comprising: an elongated fuselage;an oblique wing pivotally connected with said fuselage;a wing pivoting mechanism connected with said oblique wing and said fuselage;a rotating joint connected with said fuselage; anda strut operably connected between said oblique wing and said rotating joint, said strut being a load carrying structure and having an airfoil shaped cross section. 2. The aircraft of claim 1, wherein said wing pivoting mechanism rotates said oblique wing and said strut relative to said fuselage such that one end of said oblique wing is closer to the front of the aircraft and another end of said oblique wing is closer to the rear of the aircraft during high speed flight. 3. The aircraft of claim 1, wherein said wing pivoting mechanism rotates said oblique wing and said strut such that said oblique wing is generally perpendicular to said fuselage during low speed flight. 4. The aircraft of claim 1, wherein said strut includes first and second parallel struts operably connected between said oblique wing and said fuselage. 5. The aircraft of claim 4, further comprising a rotating or sliding joint between said fuselage and at least one of said first and second parallel struts. 6. The aircraft of claim 4, further comprising a rotating or sliding joint between said oblique wing and at least one of said first and second parallel struts. 7. The aircraft of claim 1, wherein said strut is configured to rotate about its longitudinal axis such that the leading edge of said strut generally faces the relative wind as said oblique wing and said strut rotate relative to said fuselage. 8. The aircraft of claim 1, further comprising a propulsion system rigidly connected with said oblique wing, said propulsion system including an engine, a rotating inlet, and a rotating nozzle, such that as the oblique wing moves between an unswept configuration and a swept configuration, the rotating inlet moves to redirect oncoming air flow into the engine and the rotating nozzle moves to redirect engine exit flow generally aft of the engine. 9. The aircraft of claim 1, wherein said strut is operably connected with said rotating joint, a port-side joint on said oblique wing, and a starboard-side joint on said oblique wing. 10. The aircraft of claim 1, wherein said strut includes first and second struts, wherein said first strut is operably connected with said rotating joint and a port-side joint on said oblique wing, and wherein said second strut is operably connected with said rotating joint and a starboard-side joint on said oblique wing. 11. An aircraft having variable airframe geometry for accommodating efficient flight at low speeds and as speed increases towards supersonic speeds, the aircraft comprising: an elongated fuselage;an oblique wing pivotally connected with said fuselage;a wing pivoting mechanism connected with said oblique wing and said fuselage;a propulsion system pivotally connected with said oblique wing;a rotating joint connected with said fuselage; anda strut operably connected between said propulsion system and said rotating joint, said strut being a load carrying structure and having an airfoil shaped cross section. 12. The aircraft of claim 11, further comprising a rotating joint between said strut and said propulsion system. 13. The aircraft of claim 11, wherein said wing pivoting mechanism rotates said oblique wing and said strut relative to said fuselage such that one end of said oblique wing is closer to the front of the aircraft and another end of said oblique wing is closer to the rear of the aircraft during high speed flight and wherein the longitudinal axis of said propulsion system remains generally parallel to the longitudinal axis of said fuselage. 14. The aircraft of claim 11, wherein said wing pivoting mechanism rotates said oblique wing and said strut such that said oblique wing is generally perpendicular to said fuselage during low speed flight and wherein the longitudinal axis of said propulsion system remains generally parallel to the longitudinal axis of said fuselage. 15. The aircraft of claim 11, wherein said strut includes first and second parallel struts operably connected between said propulsion system and said fuselage. 16. The aircraft of claim 15, further comprising a rotating or sliding joint between said fuselage and at least one of said first and second parallel struts. 17. The aircraft of claim 15, further comprising a rotating joint between said propulsion system and at least one of said first and second parallel struts. 18. The aircraft of claim 11, wherein said strut is configured to rotate about its longitudinal axis such that the leading edge of said strut generally faces the relative wind as said oblique wing and said strut rotate relative to said fuselage. 19. The aircraft of claim 11, wherein said propulsion system includes port and starboard propulsion systems, and wherein said strut is operably connected with said rotating joint, said port propulsion system, and said starboard propulsion system. 20. An aircraft having variable airframe geometry for accommodating efficient flight, the aircraft comprising: an elongated fuselage;an oblique wing pivotally connected with said fuselage;a wing pivoting mechanism connected with said oblique wing and said fuselage;a propulsion system rigidly connected with said oblique wing, the propulsion system including an engine, a rotating inlet, and a rotating nozzle;a brace operably connected between said propulsion system and said fuselage; anda rotating joint between said brace and said fuselage;wherein said wing pivoting mechanism rotates said oblique wing and said brace relative to said fuselage such that one end of said oblique wing is closer to the front of the aircraft and another end of said oblique wing is closer to the rear of the aircraft during high speed flight and such that said oblique wing is generally perpendicular to said fuselage during low speed flight. 21. The aircraft of claim 20, wherein the longitudinal axis of said propulsion system rigidly mounted to said oblique wing remains generally perpendicular to said oblique wing and wherein the rotating inlet moves to redirect oncoming air flow in the engine and the rotating nozzle moves to redirect engine exhaust flow generally aft of the engine. 22. The aircraft of claim 21, wherein said brace is configured to rotate about its longitudinal axis such that the leading edge of said brace generally faces the relative wind as said oblique wing and said brace rotate relative to said fuselage.
