What are 737 MAX winglets called?
split-scimitar winglets
The 737 MAX is fitted with Boeing’s trademark split winglets, also called split-scimitar winglets.
What is sharklet?
Sharklet is the world’s first technology to inhibit bacterial growth through pattern alone. The Sharklet surface is comprised of millions of microscopic features arranged in a distinct diamond pattern. The structure of the pattern alone inhibits bacteria from attaching, colonizing and forming biofilms.
What is A320 sharklet?
Sharklets are newly designed wing-tip devices that improve the aircraft’s aerodynamics and significantly cut the airline’s fuel burn and emissions by four per cent on longer sectors. This milestone makes IndiGo the first airline globally to introduce on A320 aircraft powered by IAE engines.
Why do planes have different winglets?
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 by partial recovery of the tip vortex energy.
What is an enhanced winglet?
Winglets are vertical extensions of wingtips that improve an aircraft’s fuel efficiency and cruising range. Designed as small airfoils, winglets reduce the aerodynamic drag associated with vortices that develop at the wingtips as the airplane moves through the air.
Why was Sharklet created?
History. Sharklet material is bio-inspired and was developed by Dr. Anthony Brennan, materials science and engineering professor at University of Florida, while trying to improve antifouling technology for ships and submarines at Pearl Harbor. Brennan realized that sharks do not experience fouling.
Who invented Sharklet?
Anthony Brennan
Anthony Brennan, the world-renowned material engineer and tenured professor at the University of Florida, invented the Sharklet technology. The technology was originally navy-sponsored research and currently has 11 U.S. patents while another 10 patents are under review.
What is a sharklet plane?
Winglets & Sharklets Winglets or Sharklets are upward or downward curved extensions at the wing tips. Although they cause more weight and drag, winglets improve the environmental performance of an aircraft by reducing the induced drag caused by lift, thus minimizing fuel consumption.
Why does the 777 not have winglets?
Why does the 777 not have winglets? One reason that the 777 does not feature such wingtip extensions is the operational limits these would place on the aircraft. The 777-200LR and -300ER variants of the aircraft have a wingspan of 64.8 meters. This only just falls below the upper limit for the ICAO’s aerodrome code E.
What is a Boeing 737-800 winglets?
The most noticeable feature to appear on 737s since 2000 are winglets. These are wing tip extensions which reduce lift induced drag and provide some extra lift.
What is Sharklet?
What is the difference between a winglet and a Sharklet?
There is no real difference between the two types of winglets apart from cosmetics. They are so close in design (that Airbus was proven to be infringing on a patent) that no version is better than another. However, winglets and sharklets are both solutions to inefficient wing design from earlier aircraft.
How do winglets reduce fuel consumption of aircraft?
So, winglets reduce the lift – induced drag of the aircraft, and, consequently, fuel consumption decreases. This effect is always strong if the angle of attack of the aircraft is high, namely in phases of “ slow-flight “. Among those phases are the landing, take-off and cruising phase.

What is a winglet on a car?
These folded up ends are “ winglets ” (or, depending on the shape, sharklets, wingtips, etc.). Of course, these wingtip devices do not only look great. They also have a specific purpose. This article will elaborate a bit more on this topic.
