AERODYNAMIC BODY AND HIGH-LIFT SYSTEM COMPRISING SUCH AN AERODYNAMIC BODY

摘要

Disclosed is a flow element (1) comprising an external side (3) that has a topface (3a) and a bottom face (3b) in relationto the direction of flow, and lateral end sections (5a, 5b) that form thelateral ends of the flow element (1) transversal to thetheoretical direction of flow (S). A duct (10) is arranged inside the flowelement (1). Said duct (10) encompasses a flow drive witha driving motor and a compressor means which is driven by the driving motorand is disposed in the duct (10). The duct (10) hasat least one inlet (11) on the bottom face (3b) and/or on at least one of thelateral end sections (5a, 5b) of the flow element (1) aswell as an outlet (12) on the top face (3a) of the flow element (1) in orderto influence the flow on the flow element (1). A sleeve(30) that can be rotated by means of the driving motor is located inside theduct (10). Said sleeve (30) has at least one cavity (33)which can be made to at least partially overlap with the outlet (12) on thetop face (3a) of the flow element (1) in a specific rotationalposition of the sleeve (30) such that the air that is compressed by thecompressor flows through the cavity (33) of the sleeve(30) and the outlet (12). A high-lift system comprising such a flow element isalso disclosed.
