Winglet is a wing design used to increase the efficiency of the aircraft. It is a component that improves the performance of the aircraft and increases the financial value of the aircraft, providing fuel for new generation aircraft in the face of increasing fuel prices today. The aircraft provide the lifting force required to hold it in the air thanks to the pressure that flows down the wing. Due to the pressure difference, the air flowing over the wing leaves the wingtip, creating wing vortices. The intensity of these vortices can vary depending on a number of parameters (weight, speed and wing structure of the aircraft).
Scientists have been able to reduce the operating costs of airline companies by developing parts called winglets attached to the wingtips to prevent these vortex swirls that occur all the time when airplanes are active (including take-off time, wheeling).It has been seen that the one-piece winglets are curved outward and upward, which reduces friction and improves thrust performance. It is estimated that the Winglets increased the range of the Boeing 737 aircraft by approximately 240 kilometers.In addition to reducing winglets vortices, it has also been seen that increasing total take-off weight, enabling the engine to operate more efficiently, allowing aircraft to gain less time altogether. The Boeing 737NG winglets are mounted on the wings with slight inclination. In this way drag is reduced and 4% energy saving is achieved on long distance flights.The Airbus 319 was designed to avoid the winglet stall. The Airbus sharklet was fitted to the A320 in late 2012. They aimed to save up to 3.5% on fuel, but Aviation Partners Boeing’s sloping winglet was very similar and sued.
Boeing produced for the new dual-feather wingleti 737 MAX aircraft. Curved wingletten added an additional 1.5% more ruby savings. The Boeing 737 has succeeded in saving 2% more fuel by adding a new flare called Split Scimitar and a downward protrusion .
