What is a winglet and what does it do?
When you’re in an airplane, you might curiously look out the window and see the wings of the plane, the part that lets the plane stay in the air after being lifted in the air, and at the very end of the wing, you will see an extended wing that curves upward, that’s what winglets are.
Winglets are small tips at the edge of the airplane wings that help improve the efficiency and speed, as well as the balance of the airplane while it is in the air. Without winglets, the airplane will be less balanced and the pilot will have trouble reducing wing drag. This makes winglets very effective, especially in situations where there is bad weather such as heavy rain, thunderstorms, and stronger winds. With straight wings on an airplane, there is induced pressure that slows down the airplane and makes it prone to being swayed to the left or the right. With winglets, the aircraft has an increased operating efficiency that reduces the induced pressure that is given.
It is true that winglets increase operating efficiency, but there are many more benefits that winglets offer to airplanes and pilots, these include “better design”, “blended wings”, and “raked wingtip”, all of which will help the airplane design and improve further airplane production down the line.
New and better design:
Air flows in and out of the wings, and without wingtips, there is a loss of energy with negatively impacts the airplane’s energy absorption and produces drag, which slows down the airplane and makes it potentially unstable. Winglets solve this problem by producing more aerodynamic surfaces by curving the wings at an angle reducing the energy loss, and by extension, the drag by 5%. While 5% sounds small, it makes a large effect on the energy absorption of the airplane and how well the pilot can balance the plane.
Winglets were initially frowned upon as they added extra resistance and weight to the aircraft, which is why airplanes from earlier generations did not have winglets. Modern airplanes have them now due to the improvement of winglets where they blended the winglets and curved them in such a way that they save fuel, are more efficient in the air, and have less resistance on the plane and therefore weight.
Wingtips were not familiar or popular with many airplane companies at first, but after the revision of the wingtips as raked wingtips that look more stylish and add more fuel savings, they became a phenomenon among many different airplanes and were applauded for their appearance, as well as the benefits that they served.
