Airbuss test A3. MSN0. A3. Sharklets took to the skies on a five hour flight from Toulouse initiating an elaborate test schedule to validate the performance of the new pair of winglets, study their aerodynamic behaviour and gather data for certification. Sharklets, the Airbus lingo for its new wingtip design for the Airbus A3. November of 2. 00. Air New Zealand end 2. However, Air Asia became the first operator of the sharklet equipped A3.

The 2. 5 metre tall winglets will replace the aircrafts current wingtip fence. Offered as an option on newly built aircraft, Sharklets have been specially designed for the Airbus A3. NM. Winglets An inspiration from nature. The high pressure on the lower surface of the wing creates lateral airflow outwards or away from the fuselage towards the wingtip where, on account of relatively lower air pressure above the wing, tends to spill over and swirl around the wingtip to form a vortex creating additional drag described as induced drag thereby reducing aerodynamic efficiency of the wing. NASA engineer Richard Whitcomb who developed the supercritical airfoil, a fuel efficient wing design adopted by Airbus aircraft, is also credited with the development in the 1. Difference in vortices with and without wingletseconomics of airliners. In response to the 1. NASAs Aircraft Energy Efficiency ACEE program sought ways to conserve energy in aviation. Whitcombs winglet design was predicted to reduce induced drag by approximately 2. Winglets are small aerodynamic surfaces mounted almost vertically at the wingtips. Inspiration for the design came from birds observed to curl their wingtip feathers upward when in need of high lift. A well designed winglet rises vertically and is swept back such that it significantly reduces the size of the wingtip vortex thus reducing induced drag. Winglets Their Evolution. Fig 1 The different popular winglets A, the conventional winglet sporting an angular transition between the wing and the winglet. B, A Blended winglet with the transition being the arc of a circle whose centre is at C1. C, an Elliptical Winglet, which transition and winglet forms part of an ellipse centred at C2. In 1. 98. 8, the Boeing 7. Usb 2.0 Card Reader Driver. Fig 1. A. In 1. 99. Dr Louis Gratzer, Professor of Aeronautics in the University of Washington, erstwhile Chief of Aerodynamics for Boeing, filed a patent application for an aerodynamically effective winglet termed blended winglet which provides a smooth transition between the wing, and the winglet, as depicted in Fig 1. B. Highly blended winglets have demonstrated more than 6. Blended winglet technology made its debut in 1. Performance Enhancement Program for the Gulfstream II by Aviation Partners Inc, a company established in 1. Seattle by Joe Clark and Montana businessman Dennis Washington. Boeings attention was drawn to the fuel efficiency and range enhancement on the Gulfstream II leading to a joint venture with Aviation Partners Inc to develop blended winglets for Boeing airplanes. Boeing helped Aviation Partners pioneer the technology that is available as options on 7. NG airplanes and as retrofit options on the older 7. In 2. 00. 0, Dr Fort. F Felker, a former NASA wind tunnel researcher and expert in computational fluid dynamics, filed a patent for elliptical winglets, wherein the curvature of the winglets as they extend outward from the intersection with the wings approximates part of an ellipse, as shown in Fig 1. C. This apparently ensures an elliptical distribution of lift both horizontally and vertically, resulting in lower induced drag. The very next year, Winglet Technology LLC was founded by Robert Kiser and Dr Fort Felker at Wichita, Kansas. In 2. 00. 2, a European Union EU funded, four year technology programme entitled Aircraft Wing with Advanced Technology Operation AWIATOR was launched, with focus on reduction in drag, noise, aircraft wake and improved fuel consumption. It brought together 2. European manufacturers, universities and research institutes with Airbus contributing 6. Euro 8. 0 million budget. Very large wingtip devices which include winglets, were also looked into by the program and a resin film infused composite winglet was test flown on board an Airbus A3. The host of tests were completed in early 2. Airbus A3. 20 A drive for improvement. Img 2. The closest competitor to the Airbus A3. BoeingImg 3. 73. For a flight of 1. NM, a landing weight of 6. Mach 0. 7. 8 at FL3. A3. 20 and the Boeing 7. This is 3. 00kgs lesser than a Boeing 7. The winglets contribute to a 4. With this, it was seen as obvious that an A3. Boeing deployed the winglets at the right time when crude oil prices were on the rise. With spiralling fuel prices, the need for a more efficient A3. Img 4. In the April of 2. AWIATOR winglet that flew on the A3. Airbus tested similar winglets on its prototype A3. MSN0. 00. 1, and another newly produced A3. Jet. Blue, MSN2. 75. Img 2. Closely following these tests, in the July of 2. Airbus began flight testing with Elliptical Winglets from Winglet Technology LLC Img 3. Airbus was working towards an A3. Enhanced, which was to include winglets, an aerodynamic tidy up to the engine pylons, surge tank ducts and upper belly fairing, engine improvements, weight savings and a new cabin, all aimed at reducing fuel burn by 4 5, of which the winglets alone, as Airbus chief operating officer John Leahy had said, were expected to get a couple of per cent. But in the October of 2. Airbus wasnt too sure about the winglets, stating, latest information on the A3. In late 2. 00. 8, Aviation Partners Inc and Airbus announced that blended winglets are being tested on an A3. Img 4. The winglets were specially made for the A3. No further news was heard about the results of the test, until in January 2. Jet. Blue provided an A3. Aviation Partners Inc winglets. This time however, the test was between the airline and the winglet manufacturer, with co operation from Airbus, with tests taking place in the United States. API claimed to have achieved a 5 percent fuel savings. Making it Happen. The 1. Airbus went ahead with its own design of a winglet with the sole supplier being Korean Air Aerospace Division, the aerospace manufacturing division of the Korean Air Group. Technically, the challenges with installing a winglet are the higher bending and torque loads that the structure is subjected to. This requires structural strengthening. Of the 2. 7 ribs that make up either wing of an A3. The centre wing box will also be strengthened with necessary changes to take care of both A3. Sharklets and the A3. NEO alike. Since the structure must be provisioned to fit either the Sharklet or the conventional wingtip fence, Rib 2. These reinforcements increase aircraft structural weight, compensated by an airframe wide weight reduction plan of around 2. As a result of this weight neutralisation, an aircraft which is Sharklet ready end 2. A3. 20 delivered in 2. Sharklets are standard on all A3. NEOs that will be produced 2. To handle the new engines and the added maximum takeoff weight, additional inboard rib and spar reinforcements will be incorporated when the A3. Legal. Airbus launched a legal battle on 2 December 2.
