How is it done that the wing stays connected to the fuselage?

Question

I mean, how does the wing stay connected, so that, even when turbulences occur (and therefore the forces are very strong), the wing doesn't "detach from the plane"? Just a lot of "nails" or things like that?

Answer 1

On some fighters by computer. There is a ratio of speed and turning radius. If you turn too fast the wings "depart the aircraft". Because of this a computer will not allow the pilot to turn the aircraft faster than the computer allows at a given speed.

Answer 2

The primary connections are the wing panels (bolted through splice plates to the wing center box panels); the spars (bolted through terminal fittings to the center box spars); and the aft body attachment, either a big vertical fitting bolting the spar to the overwing fuselage shell or a panel- the 'trapezoidal panel'- supporting the fuselage panels above the wheel well and connecting it to the wing.

The airplane is designed and analyzed to carry at least ultimate loads, which are 150% of limit loads- which are in turn the highest loads ever expected (based on history, atmospheric measurements, and the airplane's operating limits) in the lifetime of the fleet.  Also it is designed to carry many years of repeated flying with a high factor of safety.  The entire airplane is tested statically to ultimate load and another one cycled in fatigue for multiple lifetimes.

Your common every day turbulence is nothing to the airplane... it is a fatigue issue only.  The key loads for the wing are maneuver conditions- the 2.5G dive pullout for example- so the wing is designed for at least 3.75g.

Answer 3

The wings main spar is made to withstand huge flexing pressures. This spar passes trough the fuselage and is bolted in place by the very strongest of fasteners. There are no nails in an airplane. The aluminum skin is welded or riveted in place and the air frame itself is welded and bolted.

100 years of technological development have created a very strong safe structure that flies millions of people millions of miles every year.

Answer 4

Very large specialized bolts torqued to around 400 foot pounds of torque.

Answer 5

bolted on with large bolts

Answer 6

read the answerers above me, they got the right stuff.

as for why do the wings not fall off during turbulence, it is actually because they are flexible. if the wings were rigid, then heavy turbulence would create stress on the bolts and spars and effectively, snap them clean off.

Answer 7

As one has said it is bolted with large bolts to the center wing box. This part of the factory production splice point.  Any splice point on an aircraft is designed to be 150% or stronger in what is actually needed.
