Bonjour

Les Winglets et Airbus ... une longue histoire de désamour avec les A320 séries ...;
Une solution prévue sur des appareils neufs dans 2 ans c'est bien ... mais ce n'est pas suffisant pour Jet blue, qui aimerait trouver une solution, pour augmenter de qq centaines de nm, l'autonomie de sa flotte de A320, lesquels n'arrivent pas à faire Boston Oakland à chaque fois !
Re-Round de Discussions avec Aviation Partners, et 20 millions de $ sur la table, proposés par Jetblue qui n'en démordent pas !

JetBlue Airways CEO David Barger said the airline is eager for more progress on a winglet for the A320 that it can retrofit to its existing fleet. Air New Zealand became the launch customer for the sharklet-equipped A320 on new-build aircraft at last year's Dubai Air Show. "I'm just looking for a winglet or sharklet so we can go nonstop Boston-Oakland 100% of the time," Barger said at last week's Phoenix International Aviation Symposium, adding that the capability “is worth $20 million" to the LCC's bottom line. He said it is working with Aviation Partners and Airbus.

Bonjour à tous


http://www.ainonline.com/news/single-news-page/article/paris-2011-united-continental-orders-blended-winglets-for-767-300ers-30127/



United Continental Holdings has ordered blended winglets for its Boeing 767-300ERs from Aviation Partners Boeing (APB) of Seattle, Washington. With the order, the U.S. airline group becomes the largest single customer of APB, having ordered 375 Blended Winglet systems to date.
Together, United Airlines and Continental Airlines have ordered blended winglets for every Boeing commercial aircraft type for which APB has certified the product. Initial installations on 14 767-300ERs will begin early next year.
Blended winglet technology installed on the 767-300ER reduces fuel burn by up to 500,000 gallons per aircraft per year, while reducing carbon dioxide emissions by 5,000 tons, APB said. In addition, blended winglets can extend the range of the aircraft by as much as 320 nm, or increase payload by up to 16,000 pounds, the company claims.
Since certification in 2009, APB has taken firm and optional offers for 340 Boeing 767-300ER blended winglet systems. The company estimates that United Continental’s investment in blended winglets is saving the airline approximately $200 million per year in jet fuel costs.
APB is a joint venture of Aviation Partners and Boeing (Chalets A328, B321).

Bonjour à tous voici les split winglets à extremité en cimeterre ...

Plus facile à mettre en oeuvre que les spiroid
Et permettant tout de même 2.5% de gain sur la trainée (l'équivalent en gain de conso ?) en plus des 5-7 d'un blended winglet classique
Essais en vol sous 5 mois

http://www.flightglobal.com/news/articles/nbaa-split-winglets-latest-evolution-from-aviation-partners-363376/


Aviation Partners revealed its new blended split winglet design at NBAA, which it said is 40% more efficient than today's blended winglets.

Compared with the traditional blended design, the devices should provide an additional 2.5% reduction in drag above the 5-7% provided by basic blended winglets, according to computational fluid dynamics (CFD) studies the company has performed.

The latest design features an upper winglet and ventral strake, each punctuated by a scimitar that accounts for a 0.5% improvement in drag, said CEO Joe Clark. He is confident flight tests starting within the next five months on an as-yet unidentified business aviation aircraft will prove out the numbers: "On our last two projects, CFD predictions have been within one-tenth of 1% flight test results."


CEO Joe Clark said flight testing will begin soon

Unlike the company's more extreme spiroid winglets, which Clark said reduce drag by 11%, the split winglets can be constructed using existing blended winglets rather than a wholesale replacement of the tip, as would be the case with the spiroid. Clark said the company flight-tested its spiroid design for 75h on the company Falcon 50 this year.

Un peu plus sur les splits / scimitar blended winglets...

http://www.flightglobal.com/blogs/flightblogger/2011/10/split-scimitar-winglet-next-on.html

Et une piste pour Boeing ?
Gain de 40% par rapport aux blended winglets actuels

A noter le gain avec les spiroids !



Without the prospect of a clean-sheet design from Western manufacturers seating 150 to 210 passengers for at least a decade and a half, improving the current and future generations of 737s and A320s has put incremental improvement at the forefront of aircraft design. From in-flight entertainment and lightweight seats to wingtip treatments, the opportunities for suppliers to exploit the airframe status quo will mean big business for those trying to ring every ounce of performance from existing designs.

Joe Clark, CEO of Aviation Partners, redefined improvement in incremental efficiency a decade ago, transforming our visual expectations of what an efficient aircraft should look like, and now he's trying to do it again.

This time, Clark and his team of aerodynamicists have taken the blended winglet concept and turned it on its head. Literally. Seattle-based Aviation Partners unveiled for the first time at NBAA in Las Vegas last week its blended split winglet concept. Building on the blended winglet that is fitted more than 4,500 aircraft and nearly every Next Generation 737 that exits Boeing's Renton line, Aviation Partners has added a ventral strake and scimitar tips to the now-familiar design.

"The concept works for any airplane," says Clark, whose enthusiasm for his product is almost contagious. "It puts very little load increase into the wing, which is good. It's retrofittable on most winglets, both the scimitar tips and the ventral strake. We've done a lot of [computational fluid dynamics] work combining these all together to get us a performance of about 40% better than a normal winglet. So with winglets you'd get 5-7%, this you'll get 7-9.5%."

"For 2-3%, that's a huge number" for airlines whose biggest single cost is fuel, says Clark.

The retrofit package, he estimates, would see the skins removed from the airplane, installing a clevis fitting and some local beef up of the winglet, and would cost roughly $240,000 for operators, or about 40% more than the $600,000 for an existing set of winglets.

For airframers, the cost of developing a new aircraft, achieving a 20% improvement in fuel efficiency can run $7-10 billion, a conservative estimate as illustrated by the A380 and 787. To achieve an improvement of 2%, estimates Clark, runs at $30 to 40 million for a flight test and certification campaign, just 3% of the cost compared to an all-new clean sheet development program.


That exponential growth in the cost of an all-at-once leap in efficiency underscores the challenge of building all-new aircraft in the 21st century. Applying Red-Blue and London School of Economics academic Dr. Theodore Piepenbrock's Theory of the Evolution of Business Ecosystems, fewer options exist for major leaps in improvement. The mature "Red" environment of jetliner manufacturing likens steady incremental improvement to designing a better camel, a system built for long-term resilience not short-term speed, explains Piepenbrock's work.

"I've always told people that we're like what AMG is to Mercedes," says Clark of Aviation Partners' work. "They build fabulous cars, we just improve the performance of them. We're the refiners. As long as these big companies look at us that way, we can be very helpful to them."

Airbus plans to introduce its own "sharklet" winglet design on the A320 family next year, which will carry over to the A320neo, while Boeing will continue its current Aviation Partners Boeing winglet - a joint venture with Aviation Partners on the 737 MAX. Boeing, in the hunt for more efficiency improvement on the MAX, could find itself looking to the blended split winglet for its extra push.

The new patented scimitar tips, says Clark, are airfoils in themselves, contributing a half-percent to the overall drag improvement: "The scimitar adds quite a bit. Our CFD analysis shows the more careful you are with these tip vortexes, the better the performance is, so we've refined it to quite a good level in studying this area."

The company's experience developing and proving the efficiency gains with winglets has been significantly refined with its proprietary CFD models, each of which is tailored to a given airframe before they're even flown.

"When we did the 767 winglets, we never did a prototype and we hit the performance within one-tenth of one percent," said Clark, who also completed 75h of flight testing of a spiroid winglet design aboard his Falcon 50 earlier this year, validating an 11% improvement in drag.



Clark acknowledges that the new split design may not be right for all aircraft configurations: "Certain airplanes it's more difficult because their wings are lower, but we may use part of it, for example on a Falcon, we may use the scimitar tip and not have the ventral strake. You wouldn't get as much performance, but you'd get more. On a higher-wing airplane, one that's got a high wings, engine pods below like a Boeing or and Airbus, it's a lot easier."

No decision has been made about an aircraft as a platform for flight testing the blended split winglet concept, though Clark hopes to begin flight testing in the next six months.

Bonjour, c'est parti pour les winglets "scimitar" sur les 737NG pour 2014 (certif dès cet automne!!)
C'est united qui est client de lancement
S'adresse au rétrofit des blended winglets dans un premier temps


SEATTLE, Jan. 15, 2013 /PRNewswire/ -- Aviation Partners Boeing (APB) today announced it has launched its new Split Scimitar Winglet program with an order from United Airlines. Using a newly patented design, the program will consist of retrofitting existing Boeing Next Generation 737 Blended Winglets by replacing the aluminum winglet tip cap with a new aerodynamically shaped "Scimitar" TM winglet tip cap and by adding a new Scimitar tipped Ventral Strake. This revolutionary design was flight tested by Aviation Partners, Inc. in 2012 and demonstrated significant aircraft drag reduction over the basic Blended Winglet configuration.

(Photo: http://photos.prnewswire.com/prnh/20130115/SF42472)

APB has identified eight unique Boeing Next-Generation 737 configurations that will be considered for possible certification by the FAA; these include: the structurally provisioned and non-provisioned 737-700, 737-800, 737-BBJ, the structurally provisioned 737-900 and the 737-900ER. The initial FAA certification program will be for retrofit conversion of Blended Winglets on 737-800 aircraft that were delivered with wings structurally provisioned for Blended Winglets at time of delivery from the Boeing Next-Generation 737 production line (line numbers 778 and on). FAA supplemental type certification is targeted for October of this year. FAA certification of 737-900ER Split Scimitar Winglets is expected to follow by March 2014.

"We are very pleased that our eco-friendly friends at United have agreed to become the first airline to order Split Scimitar Winglets. This will mark the fifth program that the management team of United has partnered with Aviation Partners Boeing to launch," said Aviation Partners Boeing executive vice president and chief commercial officer Patrick LaMoria . "We are immensely grateful for United's continued support."

United has either been the launch customer for, or otherwise ordered, Blended Winglets for every Boeing commercial aircraft type for which APB offers a winglet system, in chronological order this includes the: 757-200; 737-800; 737-700; 737-900; 737-900ER; 737-500; 737-300; 757-300 and the 767-300ER. APB estimates that, once Split Scimitar Winglets are installed, APB winglet technology (Blended and Split Scimitar) will save United more than $250 million per year in jet fuel costs fleet wide.

"Fuel is United's largest, most volatile expense and we are always looking for opportunities to improve the fuel efficiency of our fleet. The Next-Generation 737 Split Scimitar Winglet will provide a natural hedge against rising fuel prices while simultaneously reducing carbon emissions," said Ron Baur , United's vice president of fleet. "We are looking forward to partnering once again with APB to launch this new winglet program."

APB expects Scimitar Winglet Systems installed on a provisioned 737-800 to save the typical airline more than 45,000 gallons of jet fuel per aircraft per year resulting in a corresponding reduction of carbon dioxide emissions of 476 tons per aircraft per year. The fuel savings can enable a 737-800 to increase its payload up to 2,500 pounds or increase its range up to 75 nautical miles. APB also expects to certify an improvement in low speed performance that will generate significant take-off benefits from high/hot or obstacle limited runways.

Nearly 5,000 Blended Winglet Systems are now in service with over 200 airlines in more than 100 countries. APB estimates that Blended Winglets have saved airlines worldwide more than 3.5 billion gallons of jet fuel to-date.

Aviation Partners Boeing is a Seattle based joint venture of Aviation Partners, Inc. and The Boeing Company.

Bonjour,

Selon AirInsight, le gain en consommation apporté par les nouveaux winglets "split scimitar"
atteindrait 3.5 à 5.5 % par rapport à un B137 équipé du modèle "classique".

Ce chiffre me parait énorme et demandera sûrement à être confirmé par les compagnies utilisatrices.
Si c'est le cas, ce modèle de winglet ne devrait pas tarder à être proposé pour d'autres
modèles d'avions.

Alors, il pèse combien ce Vortex en réalité, il va finir par valoir 15-20 % sur l'efficacité idéale de l'aile à force d'en empiler, j'en doute un peu ....  ?? 

Donc, QQ doutes sur la réalité des chiffres, et surtout, on additionne tout et n'importe quoi, et pas forcément dans les mêmes configurations de vol !
