Device on the wing for reducing induced drag

Abstract

Device on free wingtips of aircraft, models, drones, characterized in that channeled flow control (TVR - Tubular Vortex Reduction) is achieved by means of a cavity (2.0), openings / perforation (2.2), in particular by intake transversely and / or blowing out, longitudinally or transversely to the oncoming airflow, - by means of a cavity or tube-like formation (2.0) and / or perforation / wall opening (2.2) either of the cavity / nozzle (2.0) - through which the oncoming airflow (S, S') flows, - or of the wingtip (1.2), such that an obstruction or prevention of the flow around the wingtip (V) is created, in analogy to continuous wings.
