What are the different types of winglets?

What are types of winglets?

Altogether, there are several different modifications of wingtips. However, blended and canted are two of the most distinct variants. They nonetheless all serve the key purpose of reducing drag and improving fuel efficiency.

Which winglet is the best?

The shark fin-alike winglet was overall the most efficient design, followed shortly by the famous blended design found in many mid-sized airliners. The worst performing designs were surprisingly the fenced and spiroid designs, which had efficiencies on par with the wing without winglet.

What is the difference between winglets and raked wingtips?

A raked wing is not a winglet per se, but the tip of wing itself is swept back compared to the rest of the wing. The functionality is similar. The Boeing 787 Dreamliner, some Boeing 777s and the Boeing 747-8 all have raked wingtips, not winglets.

What are enhanced winglets?

Improved wing efficiency translates to more payload, reduced fuel consumption, and a longer cruising range that can allow an air carrier to expand routes and destinations. To produce as much forward thrust as possible, the winglet's airfoil is designed with the same attention as the airfoil of the wings themselves.

How Do Winglets Work? - Aviation Facts

What are blended winglets?

Blended winglets are upward-swept extensions to airplane wings. They feature a large radius and a smooth chord variation in the transition section. This feature sacrifices some of the potential induced drag reduction in return for less viscous drag and less need for tailoring the sections locally.

What is split Scimitar winglets?

Split Scimitar winglets are named after a Middle Eastern sword with a distinct curved blades ending with a sharp point. Split Scimitar winglets were developed by Aviation Partners Boeing and are available for the 737-800 and 737-900ER after entering service in 2014.

What is a 737 winglets?

Winglets are added to the end of a plane's wings to reduce drag and ultimately enable more efficient flight. They work by reducing a process known as vortex drag, caused by different air pressures converging at the tips of each wing and slowing the aircraft down.

What's the difference between winglets and Sharklets?

Winglets, as they're called, have been fitted to airliners since the '80s, but Airbus has come up with a new name for them: “sharklets.” It's part of an effort to escape a patent on the increasingly important technology that's held by a close partner of Airbus's main rival, Boeing.

Why are there no winglets on a 777?

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.

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.

Is Boeing 737-800 winglets the same as Boeing 737 MAX 8?

The main differentiator between the 737-800 and its Next Generation sibling is the engine type that each one uses. While the 737-800 primarily uses the CFM56, the Max family of aircraft are powered by the CFM LEAP 1B aircraft.

Do all planes have winglets?

As a result, models such as the Boeing 787 and 777 don't have winglets, but rather raked wingtips, or wingtips that have more backward sweep compared to the rest of the wing -- a design that is more efficient during cruise to suppress wingtip vortices. The fuel savings are comparable to winglets.

How many wings of fire winglets are there?

There are 4 books in this series.

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 Airbus A320 sharklets?

The 2.5-metre tall winglets will replace the aircraft's current wingtip fence. Offered as an option on newly built aircraft, Sharklets have been specially designed for the Airbus A320 family to reduce fuel burn by up to an additional 3.5 percent on long routes of around 3000NM. Winglets: An inspiration from nature.

What are sharklet wingtips?

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.

What is a raked wingtip?

Raked wingtips, where the tip has a greater wing sweep than the rest of the wing, are featured on some Boeing Commercial Airplanes to improve fuel efficiency, takeoff and climb performance. Like winglets, they increase the effective wing aspect ratio and diminish wingtip vortices, decreasing lift-induced drag.

What is the difference between A320 and A320 Neo?

Although Airbus A320neo a new type of aircraft, there isn't any major noticeable differences compared to the Airbus A320ceo. The Airbus A320neo has over 95 percent airframe commonality with the Airbus A320ceo, meaning sitting in the flight deck of a neo will have no real difference than in a A320ceo.

Does Boeing 747 have winglets?

The longer-range twin-engine A330 and four-engine A340 have conventional winglets, as do Boeing 747-400s. Aviation Partners, a Seattle, Washington company, has a new design it calls a "blended" winglet.

Do winglets increase lift?

Boeing says the advanced-technology winglets developed for its 737 MAX further redistribute the wing's spanwise loading, increasing the effective wingspan by generating more lift and reducing drag. Today winglets are common on jets and turboprops.

What is the most efficient wing shape?

Elliptical Wing

The elliptical wing is aerodynamically most efficient because elliptical spanwise lift distribution induces the lowest possible drag.

What is Alaska Airlines winglets?

Winglets save fuel by reducing drag, which allow aircraft to fly at cruise speed with reduced engine power. With an average annual aircraft utilization rate of 4,000 hours, winglets are expected to reduce the fuel burn of Alaska's Boeing 737s by 120,000 gallons, or 3.5 percent, per year.

How much does a 737 winglet cost?

Winglets cost anywhere from $500,000 for a 737 to more than $2 million for bigger planes. But the payoff can be rapid. Southwest Airlines estimates that it saves 54 million gallons of fuel every year thanks to equipping 93 percent of its fleet of 737s with winglets.

What is Embraer 175 enhanced winglets?

The E175 initially comes with E170 style winglets. This was changed starting in 2014 to angled winglets as part of an efficiency improvement package. The angled winglets increase the wingspan from 26.00m (85 ft 4 in) to 28.65m (93 ft 11 in). This winglet change was only made available to the E175 version.
