摘要

A ring vane (RF) designed at least in sections, which is fastened to the engine nacelle (G) at a distance (D), and this ring vane (RF), which is embodied at least in sections, is arranged at least partially surrounding the engine nacelle (G) in an area in which the air mass flow in flight within the streamlined field due to the displacement and directional effect of the engine nacelle (G) moves at least in sections in different directions to the flight direction (FR), and this ring wing (RF) with local flow (A) this air mass flow which is different from the flight direction (FR) can generate a resulting air force (LK) that contains a force component (VOR) effective in the direction of flight (FR) so that the force component (VOR) effective in the direction of flight (FR) acts on the engine nacelle (G) against its drag force (W) .
