PROBLEM TO BE SOLVED: To provide an aircraft, a wing assembly, and an upper junction part of the wing assembly which use different material between adjacent aircraft parts.SOLUTION: A wing center part 18 includes a central upper wing panel 28 and a central lower wing panel 30. A pair of ribs 32 demarcate a boundary surface between an outboard wing box and the wing center part. Junction parts among an outboard lower wing panel 26, the central lower wing panel 30, and the ribs 32 are illustrated as lower junction parts 34. Likewise, junction parts among an outboard upper wing panel 24, the central upper wing panel 28, and the ribs 32 are illustrated as an upper junction part 36. During flight, the upper junction part is in a compression state and the lower junction part is in a tension state. The outboard wing box is composed of first material with respect to second material of which the wing center part is substantially composed. An upper junction part assembly 38 is composed of third material different from the material of which the outboard upper wing panel and the central upper wing panel are composed. |
