Wing center box

from Wikipedia, the free encyclopedia

The center wing box ( English center wing box is) part of the fuselage .

The transition from the fuselage to the wing of an aircraft is implemented in most cases in such a way that a square box, the so-called center wing box, is incorporated into the fuselage, on which the wings are mounted on the left and right.

The wing center box is the most stable part of an aircraft because of the strong forces that are transferred from the wings to the fuselage. Fuselage fractures or compressions, for example due to overloading on hard landings or crashes, usually occur either in front of or behind the wing center box.

The transition from the fuselage to the wing is also known more generally as the wing root .
