## Abstract

An aircraft includes a wing with integrated ducted fans and ribs. Each respective ducted fan comprises a duct ring, a guide grille arranged within the duct ring, and an electric motor supported by the guide grille. The ribs are integrated into the guide grille. Each respective electric motor can be cylindrical, and the ribs can run tangentially along the electric motors.

## Claims

### Claim 1

An aircraft, comprising:
a wing with integrated ducted fans and ribs,
wherein each respective ducted fan comprises a duct ring, a guide grille arranged within the duct ring, and an electric motor supported by the guide grille, and
wherein the ribs are integrated into the guide grille.

### Claim 2 (depends on 1)

The aircraft as claimed in claim 1, wherein the electric motors are cylindrical, and
wherein the ribs run tangentially along the electric motors.

### Claim 3 (depends on 2)

The aircraft as claimed in claim 2, wherein the ribs run parallel to one another, and
wherein each of the electric motors is enclosed tangentially by two of the ribs.

### Claim 4 (depends on 3)

The aircraft as claimed in claim 3, wherein at least two of the electric motors are enclosed by the same ribs.

### Claim 5 (depends on 1)

The aircraft as claimed in claim 1, wherein at least two of the ducted fans are arranged one behind the other with respect to an intended incident-flow direction of the wing, or
wherein at least two of the ducted fans are arranged adjacent to one another with respect to an intended incident-flow direction of the wing.

### Claim 6 (depends on 5)

The aircraft as claimed in claim 5, wherein the ribs extend through the wing in the incident-flow direction.

### Claim 7 (depends on 1)

The aircraft as claimed in claim 1, wherein the aircraft comprises substantially perpendicular fans for generating propulsion.

### Claim 8 (depends on 1)

The aircraft as claimed in claim 1, wherein the perpendicular fans are further ducted fans.

### Claim 9 (depends on 1)

The aircraft as claimed in claim 1, wherein each of the electric motors comprises an integrated controller.

### Claim 10 (depends on 1)

The aircraft as claimed in claim 1, wherein wherein the aircraft is able to be selectively controlled in a fully autonomous manner.
