Wing arrangement comprising a main wing and a slat attached thereto opposite a flow direction in front of the main wing

A wing arrangement (10) in the form of a propeller blade of a propeller of a fixed-wing aircraft or a gyroplane or in the form of a rotor blade of a main or secondary rotor of an aircraft with wings, a helicopter or a gyroplane or in the form of a rotor blade of a rotor of a wind turbine, wherein in a vertical cross-section viewed along a flow direction (22), a length (D) of a section (32) of a slat (14) extending forwards beyond a length (A) of a main wing (12) opposite the flow direction (22) is at least 20% of a total length (C) of the wing arrangement (10) in the flow direction (22).

A wing arrangement (10) comprising a main wing (12) and a slat (14) attached thereto opposite a flow direction (22) in front of the main wing (12), wherein a gap (16) with a flow inlet (18) and a defined flow outlet (20) is formed between the slat (14) and the main wing (12), wherein the main wing (12) comprises a fixed rear section (36) and a front section (35), and wherein

• a nose (28) of the main wing (12) formed on the front section (35) of the main wing (12) opposite the flow direction (22) is at least 20% of a total length (C) of the wing arrangement (10) designed to be movable with respect to the fixed rear section (36) of the main wing (12) arranged behind the nose (28) in the flow direction (22) in order to vary the size of the flow inlet (18), wherein the size of the defined flow outlet (20) remains unchanged during the movement of the nose (28) of the main wing (12).
