Abstract: An aircraft structure having a fuselage, an engine and an air inlet for receiving air for the engine. The air inlet has a cowl which surrounds an inlet opening. The air inlet has a compression surface and a transition shoulder. The air inlet additionally has a flow guide surface, which is arranged as a local elevation in a region of the transition shoulder and extends into the inlet opening. This flow guide surface designed as a local elevation contributes to improving the displacement of the boundary layer of a fluid flowing along the aircraft structure at the air inlet.

Abstract: A fuselage for an aircraft. The fuselage has a control element with an integrated engine outlet. The control element is integrated at a rear end of the fuselage, so that the control element terminates flush with an outer skin of the fuselage in a circumferential direction of the fuselage. An outer wall of the control element surrounds the engine outlet wherein the engine outlet is directed towards an open rear side of the control element. The control element is connected to the fuselage such that the control element jointly the engine outlet is pivotable about a rotation axis with respect to the fuselage. The rotation axis runs transversely to a longitudinal direction of the fuselage and the control element functions as a tailplane when pivoting about the rotation axis.
