PANEL MEMBER, AIRCRAFT MAIN WING, AND METHOD FOR FORMING PANEL MEMBER

摘要

There is provided a panel member capable of restraining an increase in weight of a wing panel while restraining wasteful work in the manufacturing process, an aircraft main wing, and a method for forming the panel member. A wing panel 10 is formed with ridges 20 each having a dimension larger than the machining tolerance in the boundary portions between areas A1, A2, . . . . Therefore, the worker who handles the wing panel 10 can visually confirm the step portions of the areas A1, A2, . . . easily. Thereby, if a flaw or the like is found in the areas A1, A2, . . . , corrective actions can be properly taken on the actually existing flaw without mistaking the flaw for the step portion of the areas A1, A2, . . . .

主权项

1. A method of machining a metallic base material to form a panel member of an aircraft, comprising the steps of:
forming a first area of the metallic base material; forming a second area of the metallic base material, the second area being adjacent to the first area; and when a difference in thickness at a first boundary portion between the first area and the second area is less than or equal to a machining tolerance of the panel member, forming a first marking ridge in the first boundary portion, the first marking ridge protruding above a surface of the first area and a surface of the second area.
