Summary:The lift-generating system (101) includes a wing (1) having at least one suction opening (12) designed to establish a connection between the exterior of the wing and the interior (102) of the wing (1); and a suction device, a support (4) on which the wing (1) is mounted so as to be able to pivot about an axis substantially parallel to the axis (A1). The suction device includes a fan (3) located outside the wing (1) and fluidically connected to the interior (102) of the wing (1) so as to draw air through the at least one suction opening (12) of the wing, and discharge the drawn-in air through an outlet of the fan (3). The fan (3) includes an impeller (30) surrounded by a shroud (31) which defines, around the impeller, a duct that serves to guide the air discharged by the impeller, and a motor for rotating the impeller (30) about an axis substantially parallel to the axis (A1) of the wing. The shroud (31) of the fan (3) has an outlet (32) of which the axis (A32) is substantially orthogonal to the axis (A30) of the impeller (30) of the fan. The lift-generating system can be provided for a boat.
