## Abstract

An aircraft includes at least two aircraft fuselages and two elongate main wings, wherein the main wings each have an extension direction which are at an angle to one another that differs from zero. Each of the two main wings is connected to the at least two aircraft fuselages. The main wings can thus be equipped mechanically simply and so as to have a low weight, and at the same time the transmission of forces between the wings and the fuselages is performed via a plurality of connections, and this leads to a relatively low material stress.

## Claims

### Claim 1

An aircraft comprising: at least first and second aircraft fuselages and first and second elongate main wings, wherein the main wings each have an extension direction, wherein the extension directions of the two main wings are at an angle to one another that differs from zero and wherein each of the first and second main wings is connected to the at least first and second aircraft fuselages.

### Claim 2 (depends on 1)

The aircraft according to claim 1, wherein the main wings are vertically mutually offset at least in regions.

### Claim 3 (depends on 1)

The aircraft according to claim 1, wherein the first and second main wings are mutually offset in the longitudinal direction at least in regions.

### Claim 4 (depends on 1)

The aircraft according to claim 1, comprising exactly first and second aircraft fuselages, the extension directions of which are aligned so as to be mutually parallel.

### Claim 5 (depends on 1)

The aircraft according to claim 1, further comprising at least one vertical tail unit arranged on a rear end of at least one of the at least first and second aircraft fuselages.

### Claim 6 (depends on 1)

The aircraft according to claim 1, further comprising at least one engine arranged on the aircraft such that the total thrust is generated by the at least one engine symmetrically to a longitudinal axis of the aircraft.

### Claim 7 (depends on 1)

The aircraft according to claim 1, wherein an engine is arranged on each rear end of first and second external aircraft fuselages.

### Claim 8 (depends on 7)

The aircraft according to claim 7, wherein each engine comprises an engine nacelle extending radially outwards such that the nacelle absorbs the boundary layer flow of the aircraft fuselage on which the nacelle is arranged at least in part.

### Claim 9 (depends on 1)

The aircraft according to claim 1, wherein, in a region between the at least first and second aircraft fuselages, the main wings are vertically mutually spaced further apart at at least one point than in adjacent connecting regions in which the main wings are connected to the aircraft fuselages.

### Claim 10 (depends on 1)

The aircraft according to claim 1, further comprising a winglet on a rear portion of each main wing.

### Claim 11 (depends on 1)

The aircraft according to claim 1, wherein the end of each main wing has a vertical extension in a rear portion.

### Claim 12 (depends on 1)

The aircraft according to claim 1, wherein one of the first and second main wings is arranged on the upper faces of the at least first and second aircraft fuselages and the other of the first and second main wings is arranged on the undersides of the at least first and second aircraft fuselages.

### Claim 13 (depends on 1)

The aircraft according to claim 1, comprising first and second outer aircraft fuselages, each comprising at least one landing gear.

### Claim 14 (depends on 1)

The aircraft according to claim 1, wherein the main wings and the at least first and second aircraft fuselages are arranged mutually symmetrically in plan view.
