Plus de détails sur l'apex mobile: PAK FA preliminary analysis from Aerodynamics specialist: Q:What is the role of the moving front LERX in your opinion? IMHO: for a management of pitching moment level, direct lift control, and also possibly for intakes management (although doubt it) A: Yes, you're quite right. "Su" never gave up they're favourite layout of triplane. Line of Su-33 - Su-33KUB has a logical ending. I can not decide for myself if its elegant decision or not. But, certainly, the decision was feasible. The airplane is long and the efficiency of elevating rudders will be not enough for balancing it on the beyond stall angles. Apparently airplane is designed for wide range of cruising M-speeds, no less M2. Maybe more. The repositioning of front-edge bump will compensate displacement of pressure center. I guess intakes variation is classic(without front LERX). Q: With such small verticals was it done that TVC and/or other surfaces will balance it on beyond stall angles? A: Yes but TVC is not enough. I don't like the bump angle curve scheme, but I guess it was calculated and tunneled. Ill post a more detailed analysis later.

Non Lockheed says F-35 fighter excels in test flights * 'Brand-new phenomenon,' Lockheed says * Partner countries said sticking to purchase plans * Company agrees to changes to keep program on track * Lockheed shares up 1 cent at $78.20 WASHINGTON, Dec 3 (Reuters) - Lockheed Martin Corp (LMT.N) said Thursday that its multinational F-35 fighter aircraft, the Pentagon's costliest acquisition program, was performing surpassingly well in early test flight. "We have never seen, ever, success in terms of avionics stability and maturity this early in a program," said Ralph Heath, executive vice president of the company's aeronautics business unit. Lockheed, the Pentagon's No. 1 supplier by sales, projects it will sell up to 4,500 F-35s worldwide to replace its F-16s and 12 other warplanes for 11 nations initially. The United States plans to spend about $300 billion over the next 25 years to buy 2,443 F-35s. Heath said about three-quarters of the jets returning from test flights were ready to go again, a standard he said normally applied to production models, not test planes. "So it really is a brand-new phenomenon," he told a webcast Credit Suisse aerospace and defense industry conference in New York. The test flight program is far behind schedule. The development program overall is facing a potential $16 billion shortfall through 2015, according to independent studies commissioned by the Pentagon. Lockheed Martin agrees with initiatives, floated publicly last week by the Pentagon's chief arms buyer, aimed at getting the program back on track, said Bruce Tanner, the company's chief financial officer. Tanner said the company had discussed with Ashton Carter, the arms buyer, plowing some of Lockheed's future award fees into putting more aircraft into the test program and speeding development of the mission software. "We support Dr. Carter with that objective," Tanner told the conference. He did not make clear how much this might cost in terms of foregone profits. Neither the company nor the Pentagon's F-35 program office responded immediately to questions about this. Carter told reporters on Nov. 23 that he wanted Lockheed to share the cost of preventing F-35 cost overruns and schedule slips. Lockheed has a "cost-plus" development contract, meaning the government typically picks up the bill for any cost overruns. Eight countries have helped the United States finance three variants of the F-35: Britain, Italy, the Netherlands, Turkey, Canada, Australia, Denmark and Norway. Together, the core group has been projected to buy about 730 aircraft A "couple" of these countries are delaying planned purchases of the jet, a move that will boost its initial prices, Jon Schreiber, a senior official in the Pentagon program office, told Reuters on Nov. 23. Heath, at the industry conference in New York, said Lockheed's view was that the partner countries "remain very solidly supportive of the program." Competitors include Boeing Co's (BA.N) F/A-18E/F Super Hornet and the Eurofighter Typhoon, made by a consortium of British, German, Italian and Spanish companies. Lockheed's chief F-35 subcontractors are Northrop Grumman Corp (NOC.N) and BAE Systems Plc (BAES.L). Shares of Lockheed were up 1 cent at $78.20 in afternoon New York Stock Exchange trading. Qui croire? :)

Halte aux espions! Начальник Генштаба ВС РФ посетит также авиабазу Сен-Дизье, где состоится презентация истребителя-бомбардировщика "Рафаль", будет присутствовать на командно-штабных учениях штаба 9 бронекавалерийской бригады марин Сухопутных Войск Франции. Chief of General Staff of the Armed Forces visit the Saint-Dizier airbase, where is a presentation of the fighter-bomber Rafale, present at the command post exercises Headquarters 9 Brigade bronekavaleriyskoy Marine Land Forces in France. En fait la photo etait presentée comme etant le simulateur du PAK FA et plusieur Russe ont dit que non, il s'agit du simulateur Rafale. http://sukhoi.ru/forum/attachment.php?attachmentid=104849&d=1263572152 Les sieges sont les meme certe... mais j'ai jamais vu un rafale avec cette cinematique de verriere (mais je n'ai jamais vu de simulateur rafale non plus)

secret defense Bah voila, on sait pourquoi on n'aura jamais de PA2 (encore moins 2... avec 7 milliards on avait presque 3 CVF FR)

^ Comme du tuning Quand au camo j'espere pas. Deja qu'ils ont repeind les beau SEM en gris pas beau, les 2000D sont les seuls qui conservent un camo a peut pret unique et sympas (avec le vert). Y'en a marre du gris à tout va

Incroyable, c'etait pas une rumeur Le sea-Grippen est Official Saab to present Sea Gripen (carrier version of NG) Published January 14, 2010 - 19:22 Updated 14 January 2010 - 20:36 Aircraft manufacturer Saab will present shortly a new version of the JAS Gripen fighter plane, the report can now reveal. The new version is specially adapted for aircraft carriers. The background is that the Indian Navy has turned to Saab with an inquiry. The new aircraft is based on the latest NG version of the JAS Gripen, the model Saab is now trying to sell to several different countries. Of these, Brazil and India also showed interest for the aircraft carrier-based variant. Saab has been over a year working on the project and will shortly be submitting a development plan for the Indian Navy. These include the strengthening of the landing wheels, some other technical changes and a hook on landing. The new aircraft carrier-based version of the Gripen is called Sea Gripen only on the drawing board. The background to India's interest is the country's plans for a major expansion of its aircraft carrier fleet in the next 10-15 years. Overall, it is about three to five new aircraft carriers, which means that any business may be about 50 to 100 new fighter planes. Gripen is one of several aircraft that are being considered. This deal is completely off the one Indian Air Force are now at the final stage of. These are just over 100 new aircraft to be purchased and also here is JAS Gripen is a candidate. The original specification for the JAS Gripen makes that only limited modifications of the plane to make it clear aircraft carrier takeoffs and landings, according to project manager Peter Nilsson. The Swedish system with road bases has made great demands on the possibility of land on narrow roads and short runways. An environment that is similar to what happens on an aircraft carrier, he says. http://svt.se/2.22620/1.1846884/saab_tar_fram_ny_jas-modell Donc c'est la version alpha de la beta ? Ou la version "encore dans le tronc d'arbre" de la version papier?

DA n'a qu'a ouvrir un centre de maintenance en Guyane avec des ingenieurs locaux... au salaire local

Qu'en est il des differences de perf Rafale M et B/C ? Y a t il des differences en raison du poids ou autre, ou bien est ce negligible? merci

et cette news Reuters dit que la FAB prefere le Gripen. Bref c'est de la couille en barre tout ça http://www.reuters.com/article/idUSN0526029620100105?type=marketsNews que des rumeurs

Bonne année a tous, et surtout au Rafale! 2009 etait presque l'année du Rafale -> http://g2globalsolutions.com/review/?p=3177 2010 sera l'année du Rafale une bonne fois pour toute!

Ca evoque de pret ou de loin le besoin d'un PA2 ou pas ce livre bleu?

Question: Y a t il des differences de performance notoires entre le M et le C/B ? (le M etant plus lourd... ou pour d'autre raisons) ? Ou bien est ce vraiment négligible?

Il parlait du F15 version Singapoure (la version la plus aboutie du F15) ou alors du F15 Silent Eagle (une version pseudo stealth)

De memoire, le premier blog de ce genre fut "Athena et moi" non?

On peut pas mettre la tete du Mica IR sur le Meteor? Et lancer "à l'aveugle" dans la direction du F22 (pourvu qu'il n'y ait pas le soleil en face)

Uniquement si il transporte des armes nucleaires? Avec Sarko qui a sorti que le CdeG ne transporterait plus "systematiquement" des ASMP, ça va devenir la roulette russe. Plus serieusement, la doctrine français est donc bien differente que celle des US? Je rappel que pour les US, un porte avion = une ville US... toute attaque contre ce porte avion equivaut à une attaque sur une ville US et entraine donc une riposte immédiate, nucléaire si il le faut.

C'est pour cela qu'il nous faut le METEOR le plus vite possible

J'allais justement dire "au final, le plus important n'est il pas que les officiers de l'armée de l'aire UAE soient convaincu? Le reste (les forums) qu'ils soient convaincus ou pas n'est finalement que secondaire" Mais en effet avec des types ^ comme ça... D'une autre coté lui on lui fera jamais changer d'avis non plus
