Airbus has concluded testing of A320 Blended Winglets developed by Aviation Partners that it launched in December and is "4-6 weeks" from making a decision on whether to proceed with the program, Airbus Executive VP-Programs Tom Williams told media in Hamburg this week (ATWOnline, Dec. 18, 2008). Director Product Marketing-A320 Family Stuart Mann said the manufacturer is "taking time to evaluate what we've learned" and that a conclusion will be reached "in a few weeks time, hopefully. . .the result [of the testing] doesn't exist yet."
Pour le famille A320 d'Airbus, les tests de "blended winglets" sont terminés.
Il fauidrait 4 à 6 semaines pour étudier et évaluer les résultats obtenus. Airbus arrivera à sa / ses conclusion (s) dans quelques semaines encore.
Regardez la durées de vie prolongée et le regain de valeur résiduelle des B757 et B767, depuis l'arrivée des "winglets" sur ces "airframes" ! Mais, patience ! Attendons de voir les conclusions de l'évaluation précitée !In a statement, he added that winglets are "one of the elements that we are looking at for the future to ensure the A320 family stays competitive."
Later, Mann said the €100 million ($136.1 million) spent on research and development each year will keep Airbus's single-aisle aircraft family relevant for at least the next 10 years and that a next-generation replacement will require "game-changing" technology--meaning a 20% efficiency improvement--to "justify changeover costs" for airlines.
Pour les "change-over costs", ... nous sommes d'accord. Pour le calendrier, cela nous conduira jusque dans le zone de temps où l'on pourra voir les premiers "open rotors" vraiment industrialisables au début de leur industrialisation !
Voilà pour ceux qui ne voulaient pas nous croire !"The technology isn't available today. We're looking toward the end of the next decade for something like that," he said.
Elaborating yesterday, Head of Market and Product Strategy Laurent Rouaud said that "anything less than a game-changer would be almost irresponsible" and that a 40% improvement in fuel burn and a double-digit improvement in operating economics are the targets for the "end of the next decade."
Le chiffre se 40% ci-dessus correspond à la valeur situé à mi-chemin entre les 'options' dites "option 30" et "option 50"!

In January, Airbus introduced improvements on the aircraft family that it said result in a 1% cruise drag reduction. Those include redesigns of the surge tank inlet, belly fairing and engine pylon.
