Title: AERODYNAMIC BODY AND USE THEREOF
Abstract:
The invention relates to an aerodynamic body (114) comprising a main part (122) that has an upper face (124) which is designed such that a fluid (128) flows (126) over the upper face in a flow boundary layer (130). The main part (122) has at least one step (132) which projects into the flow boundary layer (130) along the main part surface (124), and at least one opening (138) for suctioning a part (140) of the fluid (128) is provided on the surface (124) of the main part (122) adjacently to the step (132) on a face (136) facing the step. Furthermore, at least one other opening (154) for blowing out at least the part (140) of the suctioned fluid (128) is provided on the surface (124) of the main part (122), and the height of the step (132) relative to the surface (124) of the main part (122) is configured such that a pressure can be set at the opening (138) in order to suction the part (140) of the fluid (128), said pressure exceeding the pressure present at the other opening (154). The invention additionally relates to the use of the aerodynamic body (114) as an airplane wing, ship propeller, turbomachine blade, or rotor blade of a wind turbine and to a method for suctioning a part (140) of a fluid (128) flowing over a surface (124) of the aerodynamic body (114).
