## Abstract

An aerial vehicle includes a fuselage, a wing, and a wing shift device. The wing shift device is configured to be coupled to the fuselage. The wing shift device comprises a plurality of apertures for coupling the wing to the aerial vehicle. The plurality of apertures are configured to permit the wing to be shifted in a forward or aft direction along the fuselage based on a center of gravity of the aerial vehicle.

## Claims

### Claim 1

An unmanned aerial vehicle (UAV) comprising:
a fuselage;
a wing; and
a wing shift device configured to be coupled to the fuselage, the wing shift device comprising a plurality of apertures for coupling the wing to the UAV, the plurality of apertures configured to permit the wing to be shifted in a forward or aft direction along the fuselage based on a center of gravity of the UAV.

### Claim 2 (depends on 1)

The UAV of claim 1, wherein the wing is detachable from the UAV and is configured to be coupled to the wing shift device using one or more fasteners.

### Claim 3 (depends on 1)

The UAV of claim 1, wherein the wing shift device is removably coupled to the fuselage.

### Claim 4 (depends on 1)

The UAV of claim 1, wherein the wing shift device is coupled to a top portion of the fuselage.

### Claim 5 (depends on 1)

The UAV of claim 1, wherein the wing shift device is coupled to a bottom portion of the fuselage.

### Claim 6 (depends on 1)

The UAV of claim 1, wherein:
the wing shift device is coupled to an interior portion of the fuselage; and
the fuselage comprises a plurality of apertures configured to permit the wing to pass through the fuselage.

### Claim 7 (depends on 1)

The UAV of claim 1, wherein the wing shift device further comprises an aeroskirt configured to decrease drag.

### Claim 8 (depends on 1)

The UAV of claim 1, wherein the UAV is configured to fly without ballast.

### Claim 9 (depends on 1)

The UAV of claim 1, wherein the wing is affixed to the wing shift device at a position which aligns the center of gravity of the UAV with a center of lift of the wing.

### Claim 10 (depends on 1)

The UAV of claim 1, wherein:
the wing comprises a first portion and a second portion;
the wing shift device comprises a first side and a second side; and
the first wing portion couples to the first side of the wing shift device and the second wing portion couples to the second side of the wing shift device.

### Claim 11

An aircraft comprising:
a wing; and
a wing shift device configured to be coupled to the aircraft, the wing shift device comprising a plurality of apertures for coupling the wing to the aircraft, the plurality of apertures configured to permit the wing to be shifted in a forward or aft direction based on a center of gravity of the aircraft.

### Claim 12 (depends on 11)

The aircraft of claim 11, wherein the wing is detachable from the aircraft and is configured to be coupled to the wing shift device using one or more fasteners.

### Claim 13 (depends on 11)

The aircraft of claim 11, wherein the wing shift device is removably coupled to the aircraft.

### Claim 14 (depends on 11)

The aircraft of claim 11, wherein the wing shift device is coupled to a top portion of the aircraft.

### Claim 15 (depends on 11)

The aircraft of claim 11, wherein the wing shift device is coupled to a bottom portion of the aircraft.

### Claim 16 (depends on 11)

The aircraft of claim 11, wherein:
the wing shift device is coupled to an interior portion of the aircraft; and
the aircraft comprises a plurality of apertures configured to permit the wing to pass through the aircraft.

### Claim 17 (depends on 11)

The aircraft of claim 11, wherein the wing shift device further comprises an aeroskirt configured to decrease drag.

### Claim 18 (depends on 11)

The aircraft of claim 11, wherein the aircraft is configured to fly without ballast.

### Claim 19 (depends on 11)

The aircraft of claim 11, wherein the wing is affixed to the wing shift device at a position which aligns the center of gravity of the aircraft with a center of lift of the wing.

### Claim 20 (depends on 11)

The aircraft of claim 11, wherein:
the wing comprises a first portion and a second portion;
the wing shift device comprises a first side and a second side; and
the first wing portion couples to the first side of the wing shift device and the second wing portion couples to the second side of the wing shift device.
