The Engineering Behind Airplane Wings

More than 100 years after the first human flight, airplanes remain a mechanical marvel that very few of us actually understand. However, it is crucial to recognize that this lack of understanding can lead to irrational fears for some nervous flyers.

The Myth of Wing Safety During Turbulence

During turbulence, the wings may appear to shake outside the window. In particularly turbulent storms, some individuals may imagine that the wings could bend so much they might snap off. This scenario, while frightening, is nearly impossible.

Understanding Wing Structure

The entire aircraft is designed to allow the wings to flex during turbulence without compromising structural integrity. Airplane wings are typically made from aluminum. However, it’s not the same aluminum found in cans; instead, it’s aerospace-grade alloy, offering strength comparable to steel.

Internal Support Systems in Airplane Wings

In addition to the wings being constructed from high-strength materials, each wing contains a hidden support system. Running along the length of the wings are two “spars,” which are metal beams that support the wings’ loads. These spars make it considerably harder for the wings to bend excessively. They run through the wings and connect to a “wing box” beneath the fuselage, ensuring that the wings remain securely attached.

Ensuring Wing Integrity

The only feasible way for an airplane wing to snap off would be through “bad maintenance,” according to Rainer Groh, a writer for the Aerospace Engineering Blog. However, it’s important to note that poor maintenance is extremely rare. Each aircraft undergoes rigorous testing and regular maintenance to ensure that planes are safe to fly without even the smallest, most invisible cracks.
