AIRCRAFT HAVING INDEPENDENTLY VARIABLE INCIDENCE CHANNEL WINGS WITH INDEPENDENTLY VARIABLE INCIDENCE CHANNEL CANARDS

Abstract

An aircraft includes a fuselage and a pair of channel wings which may vary incidence with respect to the fuselage and a pair of channel canards which can also vary incidence with respect to the fuselage and that can move independently of each other for the purpose of vertical takeoff and landing as well as forward and reverse flight. The wings may have multiple channels and may be powered by single propeller or contra-rotating propellers. The thrust to the propellers may be provided with an internal combustion engine or electric motors or a turbo prop or hybrid system. The channel wing allows the fuselage to maintain a level pitch with respect to the horizon. The aircraft will also have increased maneuverability in hover because it can independently vary the incidence of the wings and canards and be able to tightly turn about a point.

Claims

1. An aircraft comprising of a fuselage with at least one channel wing coupled to said fuselage having controlled independent variable incidence from side to side to said fuselage and at least one channel canard coupled to said fuselage with having controlled independent variable incidence from side to side to said fuselage and the channel wing and channel canard are controlled independently from each other for the purpose of vertical take-off and landing and maneuvering.

2. The aircraft of claim 1, wherein the independently variable incidence channel wings and independently variable incidence channel canards provide control for the aircraft eliminating the need for standard aircraft control surfaces.

3. The aircraft of claim 1, wherein the channel wing may be coupled with and thrust supplied by a single propeller, multiple propellers or contra-rotating propellers.

4. The aircraft in claim 1, wherein the power to the propellers may be provided by internal combustion engine, electric motors, a turbo prop or hybrid system.

5. The aircraft in claim 1, which may vary the power to and thrust of the propellers in order to provide maneuverability and variable lift.

6. The aircraft of claim 1, wherein the angle of incidence of at least one channel wing and/or channel canard is varied to allow the fuselage to remain parallel to the horizon.

7. The aircraft of claim 1, wherein the variable incidence channel wing and variable incidence channel canard allows for a smooth transition from vertical takeoff to forward flight.

8. The aircraft of claim 1, wherein the variable incidence channel wing and variable incidence channel canard allows for a smooth transition from forward flight to vertical landing.

9. The aircraft of claim 1, wherein the variable incidence channel wing and variable incidence channel canard allows for hovering flight and slow flight.

10. The aircraft of claim 1, wherein the variable incidence channel wing and variable incidence channel canard allows for reverse flight.

11. The aircraft of claim 1, wherein a portion of the channel wing and channel canard can become a ducted propeller, by enclosing the propeller with a retractable mechanism, for takeoff and landing allowing for extra thrust, reduction of noise and protection of bystanders.

DETAILED DESCRIPTION OF THE INVENTION

[0015] FIG. 1 is a diagram illustrating the aircraft at rest. In this diagram the aircraft's wing 110 is made up of four channels 120, 130, 140 and 150. The aircraft's canard 160 is made of four channels 170, 180, 190 and 195.

[0016] FIG. 2 is a diagram illustrating the aircraft in the vertical takeoff and landing configuration of the present invention. The aircraft of the present invention will be able to independently vary the incidence of the wing 210 as well as the angle of incidence of the canard 220 as required for takeoff, landing, and flight. During liftoff the channel wings and channel canards rotate such that the resultant of the thrust from the propellers and the lift from the wings and canards provide the lift required for vertical takeoff. A portion of the channel wing 230 and the channel canard 240 can become a ducted propeller, by enclosing the propeller(s) with a retractable mechanism, for takeoff and landing allowing for extra thrust, reduction of noise and protection of bystanders.

[0017] Referring to FIGS. 3A and 3B, these illustrate the aircraft in the cruise condition. The wing 310 and canard 320 are rotated to a position required to maintain lift for forward flight. FIG. 4 is a diagram of the aircraft of the present invention illustrating the aircraft in a turning hover. This figure shows the right wing 410 and left wing 420 at independent angles of incidence for a hovering left turn. The figure shows the right canard 430 and left canard 440 also positioned independently to provide both lift and thrust for a tight hovering left turn.

[0018] FIG. 5 is a diagram illustrating the aircraft flying in reverse flight. Referring to this figure, the wing 510 and 520 is at the angle of incidence for the greatest amount of lift, while the canards 530 and 540 are positioned to provide both lift and reverse thrust.

[0019] FIG. 6 is a close up of a channel of the aircraft and shows a possible contra-rotating configuration with high thrust propellers 610 and 620. The contra-rotating propeller system allows for high thrust and lift from the channel. The internal combustion engine(s), electric motor(s), turbo prop or hybrid power system may reside in the nacelle 630.

[0020] While the preferred embodiment and various alternative embodiments of the invention have been disclosed and described in detail herein, it may be apparent to those skilled in the art which various changes in form and detail may be made therein without departing from the spirit and scope thereof.
