Sharklets can reduce fuel burn by 3.5%
Sharklets, Airbus's new wingtip design for the Airbus A320 family, can reduce fuel burn by 3.5%. They were launched at the Dubai Airshow in November 2009 and were offered only on new-build aircraft, with a $900,000 list price per shipset. Sharklets add 200 kilograms but offer a 3.5% fuel burn reduction on flights over 2,800 kilometres.
The A320's CFM56-powered variant has a fuel consumption of around 2,400-2,600 kilograms per hour. The A320neo, meanwhile, consumes 2,005-2,063 kilograms of fuel per hour. The A320's sharklet variant, on the other hand, consumes 2,500 kilograms of fuel per hour per engine.
The A320's sharklets improve fuel efficiency by reducing wingtip vortices and improving the lift-to-drag ratio. They also boost take-off and climb performance, providing significant gains in payload and range. Sharklets are expected to improve the plane's takeoff performance, reducing the amount of harmful emissions released by the aviation industry. If all aircraft were equipped with sharklets, each could cut its CO2 emissions by about 1,000 tons per year.
In general, fuel efficiency in aircraft can be increased by improving aerodynamics, reducing weight, and improving engine brake-specific fuel consumption and propulsive efficiency or thrust-specific fuel consumption. Average fuel burn in new aircraft fell 45% from 1968 to 2014, a compounded annual reduction of 1.3% with a variable reduction rate.
