Abstract

An aircraft comprising a fuselage; a main wing provided on a fuselage lower side and including a center wing and an outer wing; and a fairing covering at least a lower surface of the center wing, and a seal interposed between an end edge in a right-left direction of the fairing and an outer wing lower surface. In the aircraft, a most outboard fitting located on a most outboard side out of fittings respectively provided at a plurality of positions in the right-left direction of the fairing, and an outer wing fitting provided on the outer wing are pin-coupled via a pin or pins extending along a front-rear direction. The outer wing fitting is coupled to the outer wing at a position on an inboard side with respect to the end edge and other than a position of a joining structure for joining the center wing and the outer wing.

Claims

1. An aircraft comprising:

a fuselage;

a main wing that is provided on a lower side of the fuselage; and

a fairing that covers a lower surface of at least a center portion of the main wing,

the main wing including

a center wing that is located at the center portion, and

an outer wing that is joined to the center wing in a right-left direction of the center wing, and

a seal being interposed between an end edge in a right-left direction of the fairing and a lower surface of the outer wing,

wherein a most outboard fitting that is located on a most outboard side of a plurality of fittings provided at a plurality of positions in the right-left direction of the fairing, and an outer wing fitting that is provided on the outer wing are pin-coupled via a pin or pins extending along a front-rear direction, and

the outer wing fitting is coupled to the outer wing at a position on an inboard side with respect to the end edge and other than a position of a joining structure for joining the center wing and the outer wing.

2. The aircraft according to claim 1, wherein the pin or pins that are provided at least at the most outboard fitting are located on the inboard side with respect to the end edge and on the outboard side with respect to the joining structure.

3. The aircraft according to claim 1,

wherein the most outboard fitting and the outer wing fitting are pin-coupled via a link.

4. The aircraft according to claim 2,

wherein the most outboard fitting and the outer wing fitting are pin-coupled via a link.

5. The aircraft according to claim 3,

wherein the outer wing fitting is located on the outboard side with respect to the most outboard fitting.

6. The aircraft according to claim 4,

wherein the outer wing fitting is located on the outboard side with respect to the most outboard fitting.

7. The aircraft according to claim 1,

wherein a splice plate constitutes the joining structure.

8. The aircraft according to claim 1,

wherein the seal is made of an elastic material,

the seal comprises a fixed portion that is fixed to a back side of the end edge, and a sealing portion that closes a space between the end edge and the lower surface of the outer wing, and

the sealing portion is swingably deformable with respect to the fixed portion.

9. The aircraft according to claim 1,

wherein the most outboard fitting comprises:

a first fixed portion that extends from an end portion of a stiffener that is located below the joining structure toward an outboard side along a panel constituting the fairing, and

a first pin coupling portion that is continuous to an end portion of the first fixed portion and where a first pin is provided.

10. The aircraft according to claim 1,

wherein the outer wing fitting comprises:

a second fixed portion that is coupled to a stringer via a lower-side skin of the outer wing, and

a second pin coupling portion that is continuous to the second fixed portion and where a second pin is provided.
