Wing root - part of the wing of an aircraft located closer to the fuselage . Usually, the wing root is attached to the fuselage of the aircraft (as, for example, on classic monoplanes ). However, in parasol structures, the wing may not have a clear root zone [1] .
The wing root usually experiences high bending loads in flight and during landing. When assembling the aircraft at the root of the wing, tilts and sagging are used to reduce the vortices generated by the air flow that passes between the wing and the fuselage.
The root parts of the wings have butt joints for attaching the detachable parts of the wings. Various electrical, hydraulic, pneumatic lines for controlling mechanization , engines, etc. are drawn through the connector in the wing root section. Fuel pipelines connecting the tanks inside the fuselage to the engines also pass through the connector in the wing root.
