摘要： A lift arrangement for an aircraft (2) comprises an aircraft fuselage section with an outside (3), an aerodynamic lift body (6, 8)attached to the aircraft fuselage section and extending from the aircraft fuselage section outwardly, and a pair of movably held add-on bodies (12)arranged upstream of a leading edge (14) of the aerodynamic lift body (6, 8). The add-on bodies(12) comprise an aerodynamically effective surface and are equipped with incoming airflow to generate vortices (18) that impinge on the aerodynamic lift body (6, 8), thus leading to an increase inlift on the aerodynamic lift body (6, 8). Consequently it becomes possible with simple means to effectively influence lift generation on a lift body (6, 8), in particular to compensate for loss of lift as a result of icing. Preferably, the add-on bodies are moveable, and, when operational conditions do not require the use of said add-on bodies, can be moved to a neutral position in which they do not project into the flow around the aircraft, and are thus not effective from the point of view of fluid dynamics.
