초록

In addition to reducing airframe noise, the tip fence tends to decrease drag and to increase lift, thus improving the overall aerodynamic performance of the aircraft. Another advantage presented by the tip fence lies in the simplicity of its design, its elegance, and its ready ability to fit on the wing components, such as the flaps and the slats. Furthermore, it does not require non-standard materials or fabrication techniques, and it can be readily, easily and inexpensively retrofited on most of the existing aircraft, with minimal design changes.

청구항

[ What is claimed is:] [1.] An aircraft wing comprising in combination:a high-lift system formed of a plurality of flaps, at least some of which having an outboard tip and an inboard tip; anda lift-generated noise reduction tip fence secured to at least one of said outboard tip and inboard tip of at least one of said flaps, and said tip fence moving with said at least one of said flaps, for reducing airframe aerodynamic noise generated at said one of said outboard tip and inboard tip.
