Abstract

A system and method to control flight of an aircraft. The aircraft having an engine with a rotatably nozzle assembly configured to create forward propulsion and yaw control of the aircraft. The engine exhaust passing through the nozzle is redirected with a valve disposed within the nozzle. Lift is created with a lift system carried by the wing of the aircraft. Additional lift is created during flight with a retractable wing extension disposed within the wing of the aircraft.

Claims (50)

1. An aircraft, comprising:

an engine exhaust duct;

a nozzle assembly rigidly attached to and concentrically aligned with the engine exhaust duct, the nozzle assembly having a first nozzle and a second nozzle in gaseous communication with the engine exhaust duct, the first nozzle being configured to redirect engine exhaust gas in a different direction relative to redirected gas from the second nozzle;

a rotatable valve disposed within the nozzle assembly, the valve being configured to rotate concentrically to the engine exhaust duct, the rotatable valve having:

a scoop portion in gaseous communication the engine exhaust duct, the scoop portion being configured to redirect all engine exhaust gases leaving the engine exhaust duct to the first nozzle and/or the second nozzle;

wherein the scoop is selectively contoured to reduce turbulent flow as the exhaust gas is channeled from the exhaust duct to the first nozzle and/or the second nozzle;

a wing extension carried within a wing of the aircraft, the wing extension being configured to extend from the wing in an extended position and retract within the wing while in a retracted position; a vertical lift system carried by the wing of the aircraft, the lift system being configured to create vertical flight;

the lift system comprising:

a conduit extending through the thickness of the wing;

a rotor positioned within the conduit; and

a vane operably associated with the rotor, the vane being configured to redirect rotor downwash from the rotor.

2. The aircraft of claim 1 , the sleeve valve further comprising:

a spindle concentrically aligned with the engine exhaust duct, the spindle being rotatably attached to the nozzle assembly.

3. The aircraft of claim 1 , further comprising:

a driver system operably associated with the wing extension, the driver system being configured to extend and retract the wing extension.

4. The aircraft of claim 3 , the driver system having:

a driver; and

a threaded shaft, the threaded shaft being attached to the wing extension and threadingly coupled to the driver;

wherein the driver rotates the threaded shaft as the wing extension transitions between the extended position and the retracted position.

5. The aircraft of claim 1 , further comprising:

a locking system operably associated with the wing extension, the locking system being configured to secure the wing extension in the retracted position.

6. The aircraft of claim 1 , further comprising:

a bearing system disposed within the wing, the bearing system being configured to slidably receive the wing extension.

7. The aircraft of claim 6 , the bearing system having:

a housing having an inner contoured surface area, the inner contoured surface area matching an outer contoured surface area of the wing extension, the housing being configured to prevent pivoting movement of the wing extension while in the extended position; and

a material having a low-coefficient of friction, the material being disposed between the inner contoured surface of the housing and the outer contoured surface area of the wing extension.

8. The aircraft of claim 1 , wherein the rotating valve further comprises:

a sleeve vane disposed within the scoop portion, the sleeve vane being configured to redirect gas channeled through the scoop portion.

9. An aircraft, comprising:

an engine in gaseous communication with a nozzle assembly, the nozzle assembly having a plurality of nozzles for redirecting gas from the engine, the engine and nozzle assembly being configured to provide forward flight and yaw-rotational flight;

a rotating valve disposed within nozzle assembly, the rotating valve being configured to redirect the gas from the engine through one of the plurality of nozzles;

a lift system configured to create lift; and

a wing extension carried within a wing of the aircraft, the wing extension being configured to extend outside the wing in an extended position, and retract within the wing during a retracted position;

the lift system comprising:

a conduit extending through the thickness of the wing;

a rotor positioned within the conduit; and

a vane operably associated with the rotor, the vane being configured to redirect air passing through the conduit.

10. The aircraft of claim 9 , further comprising:

a bearing system disposed within the wing, the bearing system being configured to slidably receive the wing extension.

11. The aircraft of claim 9 , the bearing system having:

a housing having an inner contoured surface area, the inner contoured surface area matching an outer contoured surface area of the wing extension, the housing being configured to prevent pivoting movement of the wing extension while in the extended position; and

a material having a low-coefficient of friction, the material being disposed between the inner contoured surface of the housing and the outer contoured surface area of the wing extension.

12. The aircraft of claim 9 , further comprising:

a driver system operably associated with the wing extension, the driver system being configured to extend and retract the wing extension.

13. The aircraft of claim 12 , the driver system having:

a driver; and

a threaded shaft, the threaded shaft being coupled to the wing extension and threadingly coupled to the driver;

wherein the driver rotates the threaded shaft as the wing extension transitions between the extended position and the retracted position.

14. The aircraft of claim 9 , further comprising:

a locking system operably associated with the wing extension, the locking system being configured to secure the wing extension in the retracted position.
