Abstract

A helicopter has a fuselage, a main rotor system connected to the fuselage and configured to rotate in a rotor direction, the main rotor system comprising a retreating rotor blade side and an opposing advancing rotor blade side, and a first wing extending from the fuselage on the retreating rotor blade side. The helicopter comprises no tail rotor system and comprises no counter-rotating rotor system coaxial with the main rotor system.

Claims (31)

1. A helicopter, comprising:

a fuselage;

a main rotor system connected to the fuselage and configured to rotate in a rotor direction, the main rotor system comprising a retreating rotor blade side and an opposing advancing rotor blade side;

a first wing extending from the fuselage on the retreating rotor blade side, at least a portion of the first wing being located rearward relative to an axis of rotation of the main rotor system; and

a thrust generator carried by the first wing, the thrust generator being located rearward relative to the axis of rotation of the main rotor system;

wherein the helicopter comprises no tail rotor system and comprises no counter-rotating rotor system coaxial with the main rotor system; and

wherein the helicopter comprises no tail supported wing.

2. The helicopter of claim 1 , further comprising:

a flaperon carried by the first wing.

3. The helicopter of claim 2 , further comprising:

a second wing extending from the fuselage on the advancing rotor blade side.

4. The helicopter of claim 3 , further comprising:

a flaperon carried by the second wing.

5. The helicopter of claim 3 , further comprising:

a thrust generator carried by the second wing.

6. The helicopter of claim 3 , further comprising:

a flaperon carried by the second wing; and

a thrust generator carried by the second wing.

7. The helicopter of claim 2 , wherein the main rotor system comprises a hub and wherein hub forces are transferred to a crossmember so that hub forces are transmitted to the first wing.

8. The helicopter of claim 2 , wherein the thrust generator comprises an electric motor.

9. The helicopter of claim 2 , wherein the thrust generator comprises a convertible engine.

10. The helicopter of claim 2 , wherein the thrust generator comprises a turbo shaft engine.

11. The helicopter of claim 10 , wherein the turbo shaft engine selectively powers the main rotor system.

12. The helicopter of claim 2 , wherein the helicopter comprises a single engine located centered in a left-right direction.

13. The helicopter of claim 2 , wherein the thrust generator is reversible so that thrust is selectively provided in a first direction and a second direction opposite the first direction.

14. The helicopter of claim 2 , wherein the helicopter comprises a generator configured to provide electrical power to the thrust generator.

15. The helicopter of claim 2 , wherein the flaperon comprises a split flaperon configured to create drag for yaw control.

16. The helicopter of claim 2 , wherein the thrust generator comprises a reversible electric motor and an elliptical or nonsymmetrical airfoil.

17. The helicopter of claim 2 , wherein the thrust generator is movable relative to the first wing.

18. The helicopter of claim 2 , wherein the thrust generator is located on a tip of the first wing.

19. The helicopter of claim 2 , wherein the helicopter comprises a hydraulic pump configured to power the thrust generator.
