Abstract
Vortex generators are arranged on the edges of aircraft wing control surfaces to generate smaller vortices that weaken the main vortex that would otherwise be generated at these areas, and thereby reduce the aerodynamic generation of noise. Each vortex generator includes plural elongated elements in the form of rigid rods or flexible bristles protruding laterally outwardly from the respective edge of the control surface. The vortex generators are preferably arranged on the inboard and outboard edges of high lift flaps and slats.
Claims19
In an aircraft including a fuselage, a wing and control surfaces selected from the group of a high-lift flap, a slat, a spoiler, an aileron, an elevator and a rudder,
- an improvement for reducing aerodynamically generated noise of air flowing over said aircraft, wherein said improvement comprises a vortex generator arranged on a lateral end of one of said control surfaces.
