pour le 16, même si je ne connais pas le russe, il doit s'agir de la taille des pneus, et non celle des disques de frein.
sur la différence entre 117S et 117, et bien en gros le 117 est le moteur intérimaire du T-50, possède un diamètre de soufflante plus gros qu'un Al-31F ou un 117S, et doit pousser dans les 15T, alors que le 117S est le moteur du Su-35S et pousse 14T

Vympel plans to develop air-to-air missiles for Russia's PAK FA fighter
19-May-2006 Jane’s Missiles and Rockets
Russia's Vympel (Toropov) State Engineering Design Bureau Joint Stock Company (JSC) is developing advanced air-to-air missiles of short, medium and long range for use on the planned fifth-generation fighter (PAK FA), writes Yevgeniy Letunovsky. According to Vympel chief designer Gennady Sokolovsky, the new missiles are being designed for carriage within an internal weapons bay. Stowing the missiles in an internal bay helps to reduce a fighter's radar cross-section (RCS). The F-22 and F-35 incorporate weapons bays, and the PAK FA will be the first Russian fighter with this feature.
Sokolovsky said that the new missiles will incorporate advanced concepts in areas such as configuration, propulsion, guidance and warhead technology, and are intended to allow the PAK FA to win air superiority over Western aircraft such as the Lockheed Martin F-22 and F-35, and the Eurofighter Typhoon.
Under a reorganisation of the Vympel design bureau, Gennady Sokolovsky (who formerly had the dual role of both General Designer and General Director) now serves as General Designer. The General Director of the Vympel is Victor Rats, while Peter Vasilev is chief of the design department.
Another goal of the programme is to create missiles of all-Russian manufacture. Many current air-to-air missiles carried by Russian aircraft incorporate subsystems provided by manufacturers in countries such as Ukraine. For example, both current versions of the R-73 - the R-73K (fitted with the Krechet radar proximity fuze) and the R-73L (with the Yantar laser proximity fuze) - are based on the Mayak-80 series of infrared (IR) seekers produced by the Arsenal State Kiev Enterprise in Ukraine, an autopilot produced by the Moscow-based AVIONIKA MNPK, and the RDTT-295 solid-propellant rocket motor developed by the ISKRA State Unitary Enterprise in Moscow.
For many years following the break-up of the former Soviet Union, political factors slowed work on creating improved R-73 variants. However, two interim models were produced - the K-74 (probably begun as izdeliye 740), with an improved Mayak-80M IR seeker operating at angles of +/-60ⅹ off boresight, and the K-74M (izdeliye 750) with an angle of +/-75ⅹ.
For the PAK FA, Vympel is developing two new missiles based on R-73/R-74 technology. The first of these is izdeliye 760. Based on the K-74M, this is intended to match the performance of the MBDA Advanced Short-Range Air-to-Air Missile (ASRAAM) and the Raytheon AIM-9X Sidewinder. It will have an improved IR seeker, an inertial control system, a datalink receiver for target updates and an advanced rocket motor with a longer burn time. To make the missile suitable for internal carriage, its cross-section will be reduced to 320x320 mm.
To maximise the weapon's coverage, it can be fired in lock-on-after-launch (LOAL) mode, starting under inertial control before achieving in-flight lock-on. It will be able to engage targets up to 160ⅹ from the aircraft's heading.
According to a Vympel representative, izdeliye 760 is about to begin flight tests. Development is due to be completed in 2010.
The follow-on K-MD (izdeliye 300) is intended to outperform the ASRAAM and AIM-9X. Although it will draw on the experience gained with the R-73/R-74 series, for most practical purposes it will be an all-new missile.
Its guidance system will be based on a new IR seeker incorporating a focal-plane array (FPA). This will have more than twice the lock-on range of the izdeliye 760 seeker, a high resistance to countermeasures and a target-recognition capability.
Russian air-to-air missile programmes have been slow to adopt FPA technology, which is already used in 'dogfight' missiles such as the AIM-9X, ASRAAM, the Diehl BGT Defence IRIS-T and Rafael's Python-4 and Python-5. Russian work in this field is still at an early stage.
The reason for this time lag is essentially historical - until now, the IR seekers for the R-73/74 series and other Russian short-range air-to-air missiles were developed by Arsenal in Kiev.
According to Peter Vasilev, chief of the Vympel design department, several Russian companies are candidates for the task of creating a state-of-the-art FPA-based seeker. Obvious candidates are the Geophizika JSC or GNPP Impulse companies, but the Azovskii Optiko-Mekhanicheskii Zavod (AOMZ) recently announced that it planned to work on advanced seeker technology.
Geophizika was responsible for the 36T IR seeker for the R-27T air-to-air missile, and for semi-active laser seekers such as the 24N1 used on the KH-29L and KH-25L air-to-surface missiles, and the 27N for KAB-500L and-1500L laser-guided bombs, while AOMZ manufactured all three. GNPP Impulse (formerly known as NII-504) has developed various types of semi-active laser and TV seekers.
The new missile will have an improved aerodynamic configuration of minimal drag, and will be powered by a dual-mode solid-rocket engine with a high specific impulse and a total burn time of about 100 seconds. The R-73 used a system of four moving thrust-vector control vanes mounted around the motor nozzle. For the K-MD, Vympel has developed what it described as 'a three-channel gas-dynamic control unit (gas control vanes)'. An adaptive warhead will provide optimised lethal effects to suit the final interception conditions.
Development of the K-MD is expected to end in 2013, giving the PAK FA a 'dogfight' weapon of much-increased range, all-round coverage and the ability to engage aircraft or missile targets.
To provide the aircraft with a medium-range and long-range armament, new missiles will be developed based on the current R-77 and R-73 respectively. As with the short-range weapon, this will be an evolutionary process, starting with improved variants and moving towards what will eventually become an all-new missile.
The use of internal carriage for all three classes of missile, and for the aircraft's air-to-surface weapons, will require the use of a new pattern of launcher able to catapult the round out of the aircraft's weapons bay. Two versions are planned. The UVKU-50L lightweight launcher is intended to carry missiles weighing up to 300 kg. Heavier weapons weighing up to 700 kg will be carried on the UVKU-50U universal launcher.

il avait été montré sur certaines photos l'emplacement de l'ouverture des petits compartiments latéraux, mais je les ai pas sous la main où je suis.
ces soutes sont adaptés pour le remplaçant du R-73
mais pas d'équivalent au MICA, qui reste une exception française avec son double rôle moyenne et courte portée
les soutes principales sont elles taillées pour recevoir des missiles moyenne et longue portée, mais aussi des armements air-sol, car c'est plus un chasseur bombardier qu'un intercepteur pur

je crois que le nom donné aux bords d'attaques mobiles de grandes dimensions est LEVCON, et seul le LCA indien utilise quelque chose qui s'en rapproche
concernant leur débattement important, surtout vers le bas, je ne pense pas effectivement que ça soit permis en croisière, mais le domaine de vol de l'avion sera surement extremement étendue à terme, et ces LEVCONs placés au dessus des entrées d'air servent aussi à réguler l'alimentation des moteurs, voir éventuellement cacher l'entrée d'air aux radars adverses
et à très fort AoA, je pense que ça pourrait être très utile pour orienter le flux d'air sur l'aile, mais aussi directement dans les entrées d'air réacteur

p*tain, j'osais encore espérer un miracle, que notre cher PR qui n'est pas manchot pour faire des coups médiatiques vienne avec Cameron au secours de la révolte pour se redonner une certaine crédibilité internationale (en tout cas c'est le seul truc qu'il lui restait pour se refaire une image)
mais là avec le Japon qui tourne en boucle, c'est bon nos dirigeants sont sauvés l'écrasement de la révolte fera 30 secondes au jité, emballez c'est peser.

faillite morale et politique complète!

entièrement d'accord avec Tancrède, la France à une occaz unique de mener une opération qui pourrait être extrêmement rentable politiquement si elle marche... et si ça ne marche pas ça ne pourra pas être pire que de laisser Kadhaf reprendre la main en disant uniquement "c'est pas bien"

le réacteur intérimaire est prêt :lol:
pour le réacteur définitif, il faudra attendre une petite dizaine d'années
le radar lui est sur les rails, et il va bientôt être intégré à un avion pour essai (un Su-30 je crois?)
sinon il va falloir attendre le 3e proto pour avoir une meilleure idée de la version de série
-
Alors le MiG-1.42 est la version de série du proto MiG-1.44 qui lui a volé.
Quelques modifications auraient été apportées à la version de série, mais elle n'a jamais quitté la planche à dessin.
Maintenant le MiG-1.44 est stocké dans un hangar à Joukovsky, et avait été mis dehors lors du dernier salon MAKS, mais sans que l'on puisse en approcher.
Les générateurs de plasma personne ne sait vraiment où ça en est, et sinon la technologie du MiG-1.44 remonte à la fin des années 80, date de sa conception, et la furtivité n'était pas un facteur pris en compte.
Donc oui les russes ont eu raison de privilégier le PAK-FA, qui est d'ailleurs moins maousse que le MiG.

en espérant qu'il y soit cette année, croisons les doigts :-\
ps : moi ce qui me fait tripper, c'est l'église orthodoxe que l'on voit au fond sur la première photo, des fois que l'on ait des doutes sur le pays... :P

eh ben, quelle agitation, et en plein pendant les congés, ils pouvaient pas attendre un peu :-X
très rapidement mes impressions sur le J-20, car j'ai beaucoup moins de temps à consacrer à ma passion maintenant
formule avec canard à l'avant, intéressant car ce sont les seuls à la mettre en pratique sur un avion furtif
le problème avec ça c'est que ça passe pour dégrader la furtivité avant
alignement des bords d'attaque et bords de fuite non concluant, alors que c'est vraiment ce qui est primordial pour la furtivité, de même les quilles ventrales encore présente, ça fait un peu trop
une taille vraiment maousse!! qui me ferais un peu penser dans son rôle à un Mig-31 furtif, conçu pour le combat BVR, pas très maniable à cause de sa taille, avec une grande autonomie, d'ailleurs les multiples projets de missiles longue portée chinois pourraient coller
mais quand on conçoit un appareil pour du combat BVR, je trouve bizarre de dégrader sa furtivité secteur avant par l'emploi de canard
l'avion sera-t-il capable de supercroisière?
ça me parait compliqué, étant donné la taille de l'engin, et sa formule pas forcément très optimisé pour la grande vitesse (canards, angle d'attaque des ailes, à comparer avec celui du T-50) il faudrait des réacteurs vraiment très puissants, alors que les chinois ne passent pas pour être en pointe sur ce domaine, et que le challenge sur tous les nouveaux projets porte plus sur le réacteur que sur la cellule

ça y est c'est signé! =D
Russia, India sign design contract for prototype multirole fighter
Russia and India signed a contract on Tuesday to jointly develop a design for a new fifth-generation multirole fighter.
The document was signed between Russia's state arms exporter Rosoboronexport and India's Hindustan Aeronautics Limited (HAL) during Russian President Dmitry Medvedev's current visit to India.
Russia's Sukhoi holding and India's Hindustan Aeronautics Limited agreed in early 2010 to jointly develop a fifth-generation fighter jet based on the T-50 design.
The project design cost is estimated at $295 million, shared equally between Russia and India.
The two sides agreed to develop both a single-seat and a two-seat version of the aircraft by 2016, initially focusing on the single-seat version.
Russia has been developing its own fifth-generation fighter since the 1990s. The current prototype, known as the T-50, was designed by the Sukhoi design bureau and built at a plant in Komsomolsk-on-Amur in Russia's Far East.
Russian officials have already hailed the fighter as "a unique warplane" that combines the capabilities of an air superiority fighter and attack aircraft.
Russia is planning to use the jointly-developed 5G fighter as an export version of T-50, while India is expecting the new fighter aircraft to enter service with its air force by 2020.

c'est le directeur du MITT qui a sauté, et il a surtout payé pour avoir présenté le bulava comme un missile simplement dérivé du topol-m, et dont la conception ne présentait que peu de risque, alors qu'en fait il s'agit d'un missile complètement différent

Rivals Join For Next Stage Of PAK FA Engine
Apr 28, 2010
By Maxim Pyadushkin
Moscow
Russia’s two engine manufacturers are to collaborate on the next stage of engine development for the Sukhoi T-50 fifth-generation fighter after years of going head-to-head as rivals.
The Moscow-based Salut and United Engine Corp. (UEC) have agreed to work jointly on the so-called second-stage engine for the T-50 being developed to meet the air force’s PAK FA requirement. NPO Saturn, now part of UEC, and Salut have been competing for this program for several years, with designs known as Eniseysk-A and Eniseysk-B, respectively.
According to senior UEC executives, the workshare on the engine to replace the T-50’s current Saturn 117 will slightly favor the corporation: UEC will have 54%, and Salut the remainder.
The decision to collaborate is driven at least in part by the likely merger of the two engine producers.
The timescale for development of the powerplant remains uncertain, as the manufacturers apparently are waiting for the military to set its requirements. In March, however, Sukhoi chief Mikhail Pogosyan said the T-50 would enter service with the air force powered by the Saturn 117. He indicated development of the second-stage engine could take another decade.
The 117 was developed by Rybinsk-based Saturn as an uprated modification of the Al-31F engine. The 29,000-lb.-thrust 117 is used on the Su-35 derivative of the Su-27 Flanker. The version fitted to the T-50 prototypes is thought to produce 30,000 lb. thrust and also comes with a new full-authority digital engine control unit.
Salut’s Eniseysk-B design was recommended by the ministry’s tender commission, according to CEO Yuri Eliseev. Under the original program schedule, the two contenders were to have demonstrated the first elements of the engine by November 2008.
Discussing Eniyesk-A, Saturn CEO Ilya Fyodorov, who also is a head of the PAK FA engine program, says the company has studied some new technologies that could be applied to the development of a powerplant for the series production PAK FA in the next in 2-3 years.
The so-called third stage of engine development, a new design, was initially planned to begin at the end of 2009, but this has yet to be announced. “Nevertheless, we have completed the conceptual design of the fifth-generation engine,” says Eliseev.
He also says that in order to minimize technical risks, Salut is already testing the element of the future engine during modernization of the Al-31F series powerplants.
The first stage of this modernization, the AL-31FM1 with a new compressor, was shown at the Engines 2010 exhibition here this month. This engine has a thrust of 27,000 lb., interval between overhauls of 1,000 hr. and service life of 2,000 hr., compared to 25,000 lb. thrust, 500 hr. between overhauls and 1,500 hr. of service life for the serial AL-31F. According to Eliseev, the AL-31FM1 already powers modernized Su-27SM Russian air force fighters. He adds that it has also been approved for installation on Su-34 bombers.
A further development, the AL-31FM2, is being bench-tested, according to the Salut CEO. This engine has a new combustor chamber and turbine and reached 29,200 lb. thrust. “If we receive funding, we are ready to start serial trials of this engine in the next year,” says Eliseev.
Also on display at the exhibition was a new KND-924-3 low-pressure compressor that, together with a new six-stage high-pressure compressor, will be used for the AL-31FM3 modification. This version is expected to have a thrust of about 30,000 lb. Eliseev stresses that all the modifications retain the size of the serial Al-31F and can be installed in versions of the Su-27 in service.
The cooperation between Salut and UEC is underpinned by the anticipated merger between the two manufacturers. Eliseev was appointed deputy head of the corporation two weeks ago. According to UEC executives, the merger with Salut will start after the latter completes its consolidation with Omsk Baranov Production Co.

Began pooling the assets to create the fifth-generation aircraft engine
The success of the first flight tests of fifth-generation Russian aircraft loaded with a fair amount of optimism domestic expert community on the future of this project. But so far not been solved yet, some key issues related to the final definition of technical persons PAK FA. One of the most important - in what terms and with what result to finalize the second phase of the engine, fully meets all the requirements for turbojet for forward-looking machines. During the exhibition "Engines-2010" became known, some new information characterizing the engine, which flew the plane, but also to shape the future of cooperation development engine of the second phase.
At the airfield the Gromov Flight Research Institute. Gromov in Zhukovsky near Moscow on April 8 from Komsomolsk-on-Amur, was taken to the first flying example of the fifth generation fighter. After assembling the aircraft in late April - early May, will begin construction phase of flight tests.
Recall the first time, PAK FA rose into the sky in the Acceptance of factory tests on January 29 this year. During this stage the stability and control of machines, the work of its major systems.One of the most important components of these flights was checking the functioning of the new engine. Despite the fact that the engine for the PAK FA scheme repeats the famous AL-31F, it is 80 percent of the new parts. This low-pressure compressor, combustor, turbine, installed at an angle of 30 degrees swivel nozzle, high pressure compressor, a digital automatic control system with elements of distributed parameters and plasma ignition system.As reported in the exhibition "Engines-2010" Chief Designer included in the Saturn SEC them. AM Swinging Yevhen Marchuk, responsible for creating an engine for the PAK FA, while developing the turbojet, a series of measures to improve reliability and increase the resource.This is necessary because the engine is more intense, has a higher temperature.
Plasma ignition system - new for an Russian engine.Until now, all ignition system to increase altitude, the possibility of running at altitude turbojet used oxygen replenishment.She demanded the availability of the entire oxygen system on board and the infrastructure at the airport. When you create a PAK FA has been tasked to ensure oxygen-free starting. Plasma ignition system installed in the main combustion chamber and afterburner. According to Eugene Marchukova, know-how inherent in the very nozzle with a plasma system: it simultaneously with the filing of kerosene is organized by the arc plasma. Also, a very serious know-how inherent in the ignition where you want in a short time give a very high voltage.
The digital control system with full responsibility as applied in the domestic aircraft for the first time. As pointed out by Yevhen Marchuk, the exception is one standby centrifugal regulator, which allows for total rejection of all the electronics, for example as a result of the impact of a nuclear explosion, to return to base at a reduced mode. Digital ACS is very mobile and flexible.Previously, analog control, change control algorithm engine takes two or three months, now, this operation takes a few minutes, sometimes not even need to stop the turbojet.That is, as noted by General Designer SEC them. AM Swinging, debugging, and debugging engine run much faster. This in turn leads to compression of the timing of testing new aircraft.
The engine of the first phase for the PAK FA is built entirely on the traditional scheme. In particular, deprived of such characteristic elements as a flat nozzle, available from a competitor of our car - F-22. However, according to Eugene Marchukova, work in the field of exhaust systems are maintained. At the stage production of technical documentation are the development of a flat nozzle and the reverse.
From the viewpoint of gas dynamics of a planar nozzle clear disadvantages because when you create the need to make the transition from a circular section (engine) on the flat.Loss of traction at the same time can be 5-7 per cent.The advantage of only one thing - providing heat invisibility by closing the turbine blades flat.This mode is used is limited: it is switched on for 5-10 minutes to overcome the enemy's air defense system. To solve this problem, such losses are allowed. But the designers of Saturn are trying to minimize the loss of up to 2-3 per cent.
These deliverables should be used in the creation of the engine of the fifth generation of the second phase.So far, the most likely candidate for the development of ideology and the layout of the turbojet was considered a "Saturn", which entered the structure of the Joint Engine Corporation. However, on 14 April the appointment of Director General of Federal State Unitary Enterprise "MMPP" Salut "Yuri Eliseev, Deputy General Director of RBC is making a new bar in the situation over this very important project.
On the second day of the exhibition "Engines-2010", April 15 during a press conference Yuri Eliseev reported on what has made "Salute" with the modernization of AL-31F engines and when you create the fifth-generation turbojet.
Conditions of the competition to develop the second stage engine for the PAK FA, according to Yuri Eliseev, envisaged construction of two prototypes: "Eniseisk-A" - "Saturn" and "Eniseisk-B" - "Salute". The first stage of the contest, involving the creation of separate parts, was completed in November 2008, the second, during which participants were required to submit demonstrators nodes, finished in June of 2009. "As for the" Salute ", - said director general of the enterprise - that is the conclusion of a commission composed of representatives from the Ministry of Defense, CIAM and CSRI-30 MO, stating that the work is done in full at a level no lower than the world, the results are recommended for use in designing fifth-generation engine. As for "Saturn", they, as far as I know, the second phase has not been completed. By the third phase, the announcement is delayed from the third quarter of last year, KB Salyut created avanproekt fifth generation engine, which according to the conclusion corresponds to the technical task.
In a press release on the appointment of RBC Yuri Eliseev deputy director general of the corporation said that the concentration of efforts of the two major domestic aircraft engine structures both in management and in the production plan will solve many problems quickly and efficiently. In particular, we are talking about the project engine for the PAK FA, which has its own work and "Salute", and the company JDC, noted in the message. As stated by Yuri Eliseev, "I have never had any doubts that the engine of the fifth generation can only be created by joint efforts. Funding should go through the JDC. The question is: what KB is an ideologue of the engine, who will assemble it and who will be responsible , personal responsibility, for the result of "a matter of principle. in size should be selected on a competitive basis." Achieved designers Salyut results suggest Yuri Eliseev assume that the lead in creating the fifth generation engine must be exactly led them to the enterprise.
Yuri Eliseev said that still does not know what range of tasks in the new place will determine his employer - CEO of RBC Andrei Reus. But according to his own idea in the JDC "Salute", in particular, should take an active part in the revival of enterprises of the Samara bush, which includes OAO SNTK them. ND Kuznetsov, OAO Motorostroitel "and OAO" Samara Design Bureau of Engineering (SKBM). There, according to Yuri Eliseev, there are problems with manufacturing and testing of new parts and assemblies in the "Salute" could help Samarans. In turn, General Director of "Salute" very interested in cooperation on facilities for railway transport.According to him, "they have a pretty good result for a capacity of up to 8 MW, have experience with liquefied gas. This experience we would be very handy."

Un article publié il y a quelque temps relatait le témoignage d'un pilote des russian knights se plaignant des Su-27 qu'ils pilotaient. Que c'était des prototypes inaptes au service actif qui leur avaient étés refourgués et que réussir à les piloter relevait déjà de la prouesse.

Le S-400 c'est tout une gamme de missiles, dont le 40N6 allant jusqu'à 400km, mais avec aussi les 9M96E et 9M96E2 de 40 et 100km, et 48N6DM de 260km. Ici ce sera probablement 40 et 100km.

On ne sais pas quand la photo a été prise. Il est tout a fait possible quelle date déjà.
L'image est intéressante car on peut la comparer avec ce schéma apparu il y a quelques années montrant la config supposée de la frégate, avec S-400 et BrahMos.
On constate que les silos pour S-400 sont bien visibles, mais ceux pour les BrahMos ne semblent pas correspondre, avec 2 silos l'un derrière l'autre au lieu d'un seul large.
