Three-dimensional lift and the occurrence of wingtip vortices can be approached with the concept of horseshoe vortex and described accurately with the Lanchester–Prandtl theory. In this view, …

May 1, 2005 · This analysis focused on two pairs of trailing vortices, with co-rotating vortices on each side of the airplane. The multiple vortex-pair instabilities grow up to five times more …

Nov 9, 2023 · At cruising altitudes, the lower air density accelerates the natural dissipation of vortices, minimizing the risk of wake turbulence for other airborne vessels. This highlights the …

Dec 12, 2024 · By capturing PIV planes slicing through helical wingtip vortex, we accurately identify the vortex centers, circulation strengths, and demarcate the upstream region, wake …

Feb 25, 2022 · For flight, lift balances the weight of an aircraft and the means for providing lift is the wing constructed to move oncoming air downward in a controlled fashion. Nature allows …

Jul 15, 2021 · AKNS wing model has a narrower vortex structure with higher strength, more energetic flow near the wing surface with higher momentum, less reverse-flow regions and …

Apr 10, 2024 · At the ends of an airplane ‘s wings, the pressure difference between air on top of the wing and air below it creates a swirling vortex that extends behind the aircraft. In this …

May 1, 2005 · The initial vortex system can be determined using a wake survey at the tail of the airplane, measured in a wind tunnel at moderate Reynolds numbers. This provides the initial …

Wingtip vortices are rotating funnels of air that leave the tip of an airplane wing as it flies. Higher air pressure formed under the wing tries to move to the lower pressure above the wing and by …

Mar 25, 2022 · As high-intensity swirling air in the vortex can extend for quite a distance behind an aircraft, it poses a danger to any aircraft following or crossing its flight path. The trailing …
