In reducing the drag resistance that occurs during takeoff Winglets, which play a major role, came to prominence with the Boeing 737 and were continuously improved, increasing aircraft performance.

What about these fins? How has it evolved over the years?

Nearly all modern commercial jet aircraft have winglets.

These wings To improve aircraft performance by reducing drag They are aerodynamic devices placed at the tips of aircraft wings. It also helps reduce the formation of strong vortices that curl behind the wingtip as the aircraft cuts through the air.

In fact, the first Boeing 737s had no distinctive winglets. In 2001, winglets were added to the 737-700 and 737-800 models. This was followed by the 737-300 in May 2003, the 737-500 in May 2007 and the 737-900 in October 2007.

Subsequently, the winglets of Boeing models were further developed.

Split Scimitar Winglets, an improvement on Boeing’s standard mixed winglets Released early 2014 and was offered as a retrofit for existing winglet aircraft.

So to further reduce drag, airplanes into 2 separate pieces with the bottom facing down he had it. After this development, many airlines started equipping their aircraft with this technology.

On the other hand, winglets have also made progress in Boeing’s MAX models.

Equipped with advanced technology, these winglets are the most advanced for a production aircraft. The most efficient winglets ever designed It was mentioned and also reduced fuel consumption by about 2%.

These fins again designed as 2.9m from lowest to highest end and developed to ensure full aircraft performance.
