Patentanspruch:Claim: Verfahren zur Beeinflussung der Zirkulationsströmung an Auftrieb erzeugenden Flächen eines Flugzeuges, wie Tragflügeln o. dgl., bei der die über die Oberfläche strömende Luft an einer oder mehreren Stellen der Fläche abgesaugt und an anderen Stellen der Oberfläche mit erhöhter, Energie ausgestoßen wird, dadurch gekennzeichnet, daß diese Luftmassen derart unter das Flugzeug bzw. unter den Tragflügel geführt werden, daß dadurch eine Verzögerung der unter dem Flugzeug" strömenden Luft bewirkt wird.Method for influencing the circulation flow to generate buoyancy Areas of an aircraft, such as wings o. The like. In which the over the surface Flowing air is sucked off at one or more points on the surface and at others Places the surface with increased, energy is emitted, characterized by that these air masses are guided under the aircraft or under the wing that thereby causing a delay in the air "flowing under the aircraft".
