What is the wingtip of an aircraft?
A wing tip (or wingtip) is the part of the wing that is most distant from the fuselage of a fixed-wing aircraft. Because the wing tip shape influences the size and drag of the wingtip vortices, tip design has produced a diversity of shapes, including: Squared-off. Aluminium tube bow. Wingtip devices are intended to improve the efficiency of fixed-wing aircraft by reducing drag. Although there are several types of wing tip devices which function in different manners, their intended effect is always to reduce an aircraft’s drag.Instead, the wide-body aircraft features raked wingtips. Raked wingtips are a newer innovation compared to winglets. It sweeps the wings’ leading edge at a more aggressive angle near the tip, similar to a dolphin’s dorsal fin. According to Boeing, the feature can reduce drag by up to 5.
What is an aircraft wing tip called?
If you are wondering what a winglet is, you are certainly not alone. Winglets are the tips or wing tips of an aircraft’s wings that reduce the induced drag of flight and thus reduce fuel consumption, among other things. Winglets are the tips or wing tips of an aircraft’s wings that reduce the induced drag of flight and thus reduce fuel consumption, among other things.By reducing drag while maintaining lift, winglets can reduce fuel burn by 2-5%. However, not all Boeing 737s are fitted with winglets. Even some Next Generation examples don’t have them, as winglets were an optional extra that some airlines chose not to invest in to save weight and costs.There are several types of winglets, but their primary function is to increase fuel efficiency by improving the lift-to-drag ratio. Studies have shown that winglets have a negligible effect on wake turbulence generation, particularly with the slower speeds involved during departures and arrivals.Raked wingtips, similar to the ones used on the 777-200LR, 777-300ER, and 787 aircraft, are used on the 747-8 instead of winglets used on the 747-400. These wingtip structures help reduce the wingtip vortices at the lateral edges of the wings, decreasing wake turbulence and drag and thereby improving fuel efficiency.
What is the function of the wing tip?
Wingtip devices are intended to improve the efficiency of fixed-wing aircraft by reducing drag. Although there are several types of wing tip devices which function in different manners, their intended effect is always to reduce an aircraft’s drag. A small addition to the wingtip is called winglet. The winglet is a piece of metal appended to the wingtip, at an angle to the wing itself. They are designed to promote the efficiency of the aircraft by reducing drag. NASA engineer Richard Whitcomb pioneered the technology in the 1970s.
Which planes have winglets?
Boeing 737 Series: Blended and split scimitar winglets are common, providing airlines with fuel savings and extended range. Airbus A320 Family: Older models use wingtip fences, while newer ones feature sharklets for improved efficiency. Boeing 757 and 767: Often retrofitted with blended winglets to enhance performance. If you are wondering what a winglet is, you are certainly not alone. Winglets are the tips or wing tips of an aircraft’s wings that reduce the induced drag of flight and thus reduce fuel consumption, among other things.
Why does the 747 8 not have winglets?
Raked wingtips, similar to the ones used on the 777-200LR, 777-300ER, and 787 aircraft, are used on the 747-8 instead of winglets used on the 747-400. These wingtip structures help reduce the wingtip vortices at the lateral edges of the wings, decreasing wake turbulence and drag and thereby improving fuel efficiency. If the 777 were fitted with winglets, this would have extended its wingspan, limiting the ability to fit at some airport gates, so Boeing made the decision to avoid adding additional weight and complexity to the aircraft design, instead using raked wingtips as a balance for performance gains, and also limiting weight .
