Abstract
An aircraft wing has an inboard section and an outboard section. The inboard section is attached (i) on one side thereof to the aircraft's fuselage, and (ii) on an opposing side thereof to an inboard side of a turbofan engine nacelle in an over-the-wing mounting position. The outboard section's leading edge has a sweep of at least 20 degrees. The inboard section's leading edge has a sweep between −15 and +15 degrees, and extends from the fuselage to an attachment position on the nacelle that is forward of an index position defined as an imaginary intersection between the sweep of the outboard section's leading edge and the inboard side of the nacelle. In an alternate embodiment, the turbofan engine nacelle is replaced with an open rotor engine nacelle.
Claims24
A wing, comprising:
- an inboard section adapted to be attached on one side thereof to a fuselage and adapted to be attached on an opposing side thereof to an inboard side of an engine nacelle in an over-the-wing mounting position, said inboard section having a leading edge and a trailing edge;
- an outboard section adapted to be attached on one side thereof to an outboard side of said nacelle, said outboard section having a leading edge and a trailing edge;
- said outboard section leading edge having a sweep of at least 20 degrees;
- said inboard section leading edge having a sweep between −15 and +15 degrees;
- and
- said inboard section leading edge extending from said fuselage to an attachment position on said nacelle, wherein the attachment position on said fuselage and said attachment position on said nacelle are forward of an index position on the inboard side of said nacelle, said index position defined as an imaginary intersection between said sweep of said outboard section and said inboard side of said nacelle.
