Abstract

Abstract:

Aircraft wake vortex will be produced by the wing tip to have a negative impact on flight safety, when a large aircraft applies flap wing to take-off and landing under a large angle of attack. Based on the Rayleigh-Ludwieg instability, a new concept flap layout is developed by adding a set of specially designed flaps. Water channel experiments reveal that the new concept flap layout can significantly promote the wingtip vortex dissipation. The wingtip vortex which is affected by flap vortex with disparate parameter combinations performs differently with respect to movement characteristics and energy. The experiments also provide references to wake vortex control, when the requirement for flight mechanics design is satisfied. Building four-vortex system reasonably by taking advantage of high-lift devices will has a significant effect on alleviating the intensity of aircraft wake, and improve the efficiency of aircraft take-off and landing at the airport.

Key words: aircraft wake vortex, Rayleigh-Ludwieg instability, flap, particle image velocimetry, water channel
