[0002] At present, the wing rib design of most aircrafts is to form a rectangular large opening to form a maintenance passage of the wing. However, when the height of the wing rib changes sharply along the chord direction, the height of the human-shaped opening will be obviously limited by the lower wing rib height at the chord position. If the human-shaped through opening is still designed as a rectangle, the height design range will be obviously reduced, and it is difficult to meet the engineering design requirements. At the same time, the rectangular large opening obviously weakens the stiffness of the rib body. SUMMARY

[0005] The wing rib structure has wing rib struts on the upper side and the lower side respectively, a plurality of cross ribs are arranged between the wing rib struts, the through opening of the octagonal shape is arranged in a four-sided box-shaped structure formed by the cross ribs and the wing rib struts, the edge of the through opening has a circumferential reinforcing rib, and the circumferential reinforcing rib has a plurality of strip-shaped reinforcing ribs in a radial form.

[0006] Preferably, one strip-shaped reinforcing rib is connected to each corner of the octagonal through opening.

[0007] Preferably, one end of the strip-shaped reinforcing rib is connected to the wing rib strut or the cross rib, and the other end is connected to the circumferential reinforcing rib.

[0008] Preferably, a plurality of lightening holes are arranged between the cross ribs and the wing rib struts.
