Abstract: Described is an aircraft, in particular a drone, with a supporting body (2) and at least two propulsion arrangements (4, 8) arranged at a distance from one another on the supporting body (2), which are designed to generate a propulsive thrust in a direction of propulsion (8b). According to a first aspect of the invention, the propulsion arrangements (4, 8) on the supporting body (2) are each mounted so as to be pivotable independently of one another about a first axis of pivoting (6) extending at an angle to the direction of propulsion (8b) and a first actuating drive (10) is provided and designed to pivot the propulsion arrangements (4, 8) independently of one another about the first axis of pivoting (6).

Abstract: An enclosure for a nacelle of a wind turbine is connected to a substructure in a manner that allows the enclosure to move relative to the substructure. An imaginary straight line extends over the panel and is aligned with an edge of the panel. The imaginary straight line defines a first sub-portion of the panel, said first sub-portion comprising the edge. The first sub-portion butts against the substructure. The first sub-portion is retained against the substructure by a tension element acting in a direction of tension. The first sub-portion can be displaced relative to the substructure in a direction which intersects the direction of tension. The invention facilitates the operation of assembling the enclosure.
