Webb8 dec. 2024 · As for the aerodynamic mechanism of wingtip slots, the emphasis can be placed on the study of the formation, development, and evolution of wingtip vortices on slotted wings. Besides, some research strategies and feasibility analyses are proposed for each part of the research. 1 Introduction Webb12 maj 2024 · Recent design innovations at the wingtips have also seen significant improvements in the aircraft’s aerodynamic performance. Raked wingtips (used mostly on Boeing models) or winglets (used mainly on Airbus models), lessen the effects of the ‘wake’ – the swirling vortex of air left behind the wing as it passes through the air at high speed.
