Method of manufacturing the wing panel, wing panel, and aircraft

摘要

PROBLEM TO BE SOLVED: To provide a wing panel for manufacturing a main wing having various curvature radii efficiently with stable accuracy, and to provide an aircraft and a manufacturing method of the wing panel.SOLUTION: A wing panel is divided into a plurality of areas A1, A2, .... When each of the areas 1, A2, ... is subjected to peening, the curvature radius Rz is set to be a fixed value in the same area. The wing panel can be formed by applying peening to each of the areas A1, A2, ... with prestrain. No template is required, thereby enabling efficient manufacturing of the wing panel.
