An aircraft for use in fixed wing flight mode and rotor flight mode is provided. The aircraft can include a fuselage, wings, and a plurality of engines. The fuselage can comprise a wing attachment region further comprising a rotating support. A rotating section can comprise a rotating support and the wings, with a plurality of engines attached to the rotating section. In a rotor flight mode, the rotating section can rotate around a longitudinal axis of the fuselage providing lift for the aircraft similar to the rotor of a helicopter. In a fixed wing flight mode, the rotating section does not rotate around a longitudinal axis of the fuselage, providing lift for the aircraft similar to a conventional airplane. The same engines that provide torque to power the rotor in rotor flight mode also power the aircraft in fixed wing flight mode.

1. An aircraft capable of fixed wing and rotor flight modes, comprising: a fuselage main body defining a longitudinal axis, the fuselage main body having a nose, a tail, and a rotatable wing attachment region disposed between the nose section and the tail section;a plurality of dual-purpose wings, including a first wing and a second wing, rotatably mounted to said wing attachment region of said fuselage main body for a fixed wing flight mode and for a rotor flight mode, in which the fixed wing flight mode is defined as flight in which said wings are maintained rotationally stationary relative to the longitudinal axis and the rotor flight mode is defined as flight in which said wings rotate about the longitudinal axis; anda plurality of engines secured to said wings, including a first engine secured to said first wing in an intermediate region of said first wing and a second engine secured to said second wing in an intermediate region of said second wing, in which the plurality of engines are each solely confined to the wings, said first engine and said second engine including propellers. 2. The aircraft of claim 1, wherein each wing includes a rear swept portion proximate to the fuselage and a forward swept portion distal to the rear swept portion. 3. The aircraft of claim 1, wherein each of the plurality of engines are secured to a corresponding wing of the plurality of wings at a prescribed semi-span distance that is disposed at or between a first calculated location and a second calculated location, in which (a) the first calculated location is a location along the semi-span calculated to optimize rotor flight mode for the corresponding wing and propulsive power of the corresponding engine,(b) the second calculated location is a location along the semi-span calculated to optimize fixed wing flight mode for the corresponding wing and propulsive power of the corresponding engine, and(c) the first calculated location and the second calculated location are no more than 25% apart along of the semi-span distance. 4. The aircraft of claim 1, further comprising fuel tanks disposed in the wings and operatively coupled to the plurality of engines. 5. The aircraft of claim 1, wherein the plurality of engines are each secured to said wings at an equalizing position along the semi-span of each wing. 6. The aircraft of claim 1, further comprising a plurality of tail stabilizing surfaces. 7. The aircraft of claim 6, wherein said plurality of tail stabilizing surfaces further comprise at least one control surface for controlling the orientation of the aircraft when the aircraft is flying in fixed wing mode or in rotor flight mode. 8. The aircraft of claim 1, wherein the plurality of dual-purpose wings consist of the first wing and the second wing; and the plurality of engines consist of the first engine and the second engine. 9. An aircraft capable of fixed wing and rotor flight modes, comprising: a fuselage main body defining a longitudinal axis, the fuselage main body having a nose, a tail, and a wing attachment region disposed between the nose section and the tail section;a plurality of dual-purpose wings, including a first wing and a second wing, rotatably mounted to said wing attachment region of said fuselage main body for a fixed wing flight mode and for a rotor flight mode, in which the fixed wing flight mode is defined as flight in which said wings are maintained rotationally stationary relative to the longitudinal axis and the rotor flight mode is defined as flight in which said wings rotate about the longitudinal axis;a plurality of engines secured to said wings, including a first engine secured to said first wing in an intermediate region of said first wing and a second engine secured to said second wing in an intermediate region of said second wing, in which the plurality of engines are each solely confined to the wings; anda plurality of fuel tanks disposed in the plurality of dual-purpose wings and operatively coupled to the plurality of engines. 10. The aircraft of claim 9, wherein the plurality of engines are each secured to said wings at an equalizing position along the semi-span of each wing. 11. The aircraft of claim 9, wherein the plurality of dual-purpose wings consist of the first wing and the second wing; and the plurality of engines consist of the first engine and the second engine. 12. The aircraft of claim 9, wherein each wing includes a proximal wing portion and a distal wing portion, having an engine of the plurality of engines secured between said proximal wing portion and said distal wing portion. 13. The aircraft of claim 9, further comprising a plurality of tail stabilizing surfaces. 14. The aircraft of claim 13, wherein said plurality of tail stabilizing surfaces further comprise at least one control surface for controlling the orientation of the aircraft when the aircraft is flying in fixed wing mode or in rotor flight mode. 15. An aircraft capable of fixed wing and rotor flight modes, comprising: a fuselage main body defining a longitudinal axis, the fuselage main body having a nose, a tail, and a wing attachment region disposed between the nose section and the tail section;a plurality of dual-purpose wings, including a first wing and a second wing, rotatably mounted to said wing attachment region of said fuselage main body for a fixed wing flight mode and for a rotor flight mode, in which the fixed wing flight mode is defined as flight in which said wings are maintained rotationally stationary relative to the longitudinal axis and the rotor flight mode is defined as flight in which said wings rotate about the longitudinal axis, wherein each wing includes a rear swept portion proximate to the fuselage and a forward swept portion distal to the rear swept portion;a plurality of engines secured to said wings, including a first engine secured to said first wing in an intermediate region of said first wing and a second engine secured to said second wing in an intermediate region of said second wing, in which the plurality of engines are each solely confined to the wings. 16. The aircraft of claim 15, wherein the first engine is disposed between the rear swept portion and the forward swept portion of the first wing, and the second engine is disposed between the rear swept portion and the forward swept portion of the second wing. 17. The aircraft of claim 15, wherein the plurality of engines are each secured to said wings at an equalizing position along the semi-span of each wing. 18. The aircraft of claim 15, wherein the plurality of dual-purpose wings consist of the first wing and the second wing; and the plurality of engines consist of the first engine and the second engine. 19.
