Abstract

An aircraft includes a fuselage and first and second pairs of aerofoils, the aerofoils of each pair extend from opposing sides of the fuselage. Each aerofoil includes a first lift body and a second lift body which is arranged behind the first lift body in a direction of flow of the aerofoil. The second lift body is pivotable relative to the first lift body between a cruising flight position in which both lift bodies together define an elongate and substantially continuous cross section of the aerofoil in the direction of flow, and a take-off/landing position in which the second lift body is angled downwards relative to the first lift body in order to increase a lift of the aerofoil. At least one engine is arranged on the second lift body of at least one of the first and second pairs of aerofoils.
