Abstract
In a wing structure for an aircraft, a rib extends in a chord direction for connecting spars to each other with upper and lower stringer through holes through which stringers of skins pass being formed in upper and lower edges of the rib. A bead is formed on the rib so as to extend between the upper and lower stringer through holes. Upper and lower ends of the bead are formed into arcuate shapes so as to surround the upper and lower stringer through holes, respectively. Thus, it is possible to enhance the buckling strength of the rib against a shear load acting on the wing of the aircraft.
Claims20
A wing structure for an aircraft, comprising:
- a plurality of spars extending in a span direction;
- a plurality of stringers arranged between the spars and extending in the span direction;
- a rib extending in a chord direction to connect the spars to each other;
- and
- skins for covering upper and lower surfaces of the spars, the stringers and the rib;
- wherein upper and lower stringer through holes through which the stringers pass are formed on upper and lower edges of the rib;
- wherein a bead is formed on the rib so as to extend between the upper and lower stringer through holes which face each other in a vertical direction, said bead including a straight portion, an upper end and a lower end;
- and
- wherein each of the upper and lower ends of the bead are formed into arcuate shapes including a forwardly projecting portion extending beyond the straight portion and a rearwardly projecting portion extending beyond the straight portion so as to surround the upper and lower stringer through holes, respectively.

- a plurality of stringers arranged between the spars and extending in the span direction;
- a rib extending in a chord direction to connect the spars to each other;
- and
- an upper skin for covering an upper surface of the spars, the stringers and the rib;
- a lower skin for covering a lower surface of the spars, the stringers and the rib;
- an upper stringer through hole on an upper edge of the rib for enabling a stringer to pass therethrough;
- a lower stringer through hole on a lower edge of the rib for enabling a stringer to pass therethrough;
- a bead formed on the rib and extending between the upper and lower stringer through holes which face each other in a vertical direction, said bead including a straight portion, an upper end and a lower end;
- and
- arcuate shapes being formed in each of said upper and lower ends of the bead said arcuate shapes including a forwardly projecting portion extending beyond the straight portion and a rearwardly projecting portion extending beyond the straight portion for surrounding the upper and lower stringer through holes, respectively.
