Abstract
A method for suctioning the boundary layer at the surface (1) of an aircraft having an air-conditioning system (4), at whose flow-critical points of the surface multiple suction openings (2) are provided, the air quantity suctioned via these being discharged to the atmosphere again via at least one outlet (7) placed in a way favorable for flow, the air quantity suctioned from the surface (1) being fed to the air-conditioning system (4) of the aircraft, via whose outlet (7) the air quantity suctioned is discharged to the atmosphere together with the exhaust air of the air-conditioning system (4), to reduce flow losses.
Claims11
A method for suctioning a boundary layer at a surface of an aircraft having an air-conditioning system, at whose flow-critical points of the surface multiple suction openings are provided for the boundary layer suctioning, the method comprising the step of:
- feeding an air quantity suctioned from the surface to the air-conditioning system of the aircraft to reduce flow losses;
- and
- discharging the air quantity suctioned to the atmosphere together with the exhaust air of the air-conditioning system via an outlet of the air-conditioning system.
A device for suctioning a boundary layer at a surface of an aircraft having an air-conditioning system by using suction openings for boundary layer suctioning, the openings being positioned at flow-critical points of the surface, the device comprising:
- a duct system and an exhaust;
- wherein the duct system feeds an air quantity suctioned from the surface to the air-conditioning system of the aircraft to reduce flow losses;
- and
- wherein the exhaust is adapted such that the air quantity suctioned exits to the atmosphere together with the exhaust air of the air-conditioning system via an outlet of the air-conditioning system.
