The small folds on the wingtips of airplanes are not an aesthetic detail. It plays a crucial role much further.

Even though they seem like small details, without them air traffic would be It could have been much more dangerous. Let’s see what these folds are, which are small but have a big function.

First we need to expose you to some boring terms.

Wings, A consequence of the “Bernoulli principle” It works like. This principle is based on the principle that the airflow over the wings increases and the pressure decreases.

Because air flows faster over the upper part of the aircraft’s wings, the pressure on the upper surface is lower than on the lower surface. This pressure difference is from the aircraft take off and stay in the air It creates the driving force that makes this possible

Swirls form.

The main air resistance (friction) in aircraft is caused by the high pressure under the wing. This means that air is blown over the wingtip before it spins in a vortex. flow upwards why is this happening.

The air under the wing moving from high pressure to low pressure around the wing tips It tends to create small vortices as the plane moves.

These swirls; It increases fuel consumption, reduces aircraft speed and reduces performance. Even An airplane flying through the same area loses its balance and is in an emergency situation. It can even lead to:

This is where the folds on the wing tips (winglets) come into play.

These little folds called “fins” you see above since the eighties It is and remains an important part of aircraft design.

Their curved shapes reduce friction, save fuel, reduce carbon dioxide and nitrogen oxide emissions and noise. Even indirectly price of airline tickets It even decreases because fuel is saved.
