The third PAK FA prototype has joined the flight test program

The first flight of the third PAK FA prototype has been performed today at Komsomolsk-on-Amur Aircraft Production Association named after Y.A. Gagarin (KnAAPO), based in Komsomolsk-on-Amur , Sukhoi Company reports. AEX.ru

The jet was piloted by the honored test-pilot of Russian Federation, Hero of Russia, Sergey Bogdan. The fighter’s flight lasted more than one hour and then it has landed at the runway of enterprise’s airfield. The flight has been performed successfully in full accordance with flight assignment. The stability testing has been performed during the flight and the work of powerplant has been evaluated. The jet has performed well on all the stages of flight. The pilot has underlined the reliable work of all the systems and equipment.

The first flight of PAK FA has been performed on January 29th 2010 in Komsomolsk-on-Amur. The second prototype has performed its maiden flight in early March 2011. The work on ground and flight testing is in progress. The first public demonstration of the fighter has taken place in Zhukovsky on August 17th 2011 at MAKS-2011 airshow. More than 100 flights have already been performed in the network of flight test program.

PAK FA program assumes creation, serialization and passing into service the fifth-generation fighter. It will help increase the combat potential of Russian air forces; it will help aircraft industry and other related industries reach a new production and technical level and will give impulse to development of school of sciences, provide a stable workload for enterprises taking part in the development and production of the jet. This top-priority program of Sukhoi will contribute to development and implementation of new materials, element base and hi-end technologies with high innovative potential for aircraft industry and the country’s economy, for development of new projects of consistent next-generation aviation systems.

“As compared to the fighters of previous generations, PAK FA has some unique features combining functions of strike aircraft and fighter. Fifth-generation fighter is equipped with new avionics with an integrated function of “electronic pilot” and advanced radar with phased antenna array. It significantly decreases the load on the pilot allowing him to concentrate on performance of tactical objectives. The airborne equipment of the new aircraft enables real-time data exchange with ground systems and other aircraft. Implementation of composites and innovative technologies, aircraft aerodynamic configuration, visibility mitigation measures for the engine provide the outstanding low level of radar, optical and infra-red visibility. It increases the combat efficiency of the fighter in any weather and lighting conditions”, - the compan

'Indo-Russian fighter jet better than Chinese, US aircraft'


NEW DELHI: The Indo-Russian fifth generation fighter aircraft (FGFA) is superior than the similar Chinese and American rival fighter jets which include the J 20 Black Eagle and the F-22 Raptor, a top Russian military commander has claimed.

India and Russia are jointly developing the Sukhoi T-50 PAK FA FGFA for their respective air forces and have plans of producing over 400 of these highly-advanced fighter jets.

Commander of the Russian Air Force Colonel General Alexander Zelin told Russian news agency RIA Novosti that his country's government has decided to give top priority to the development of the joint venture aircraft.

"While comparing Russia's T-50 PAK FA with the US F-22 Raptor and China's Chengdu J-20 Black Eagle, one concludes that the T-50 is superior to its foreign analogues in terms of its maximum speed in afterburner and standard modes, maximum range and thrust-to-weight ratio," he said.

The Russian Air Force Commander said that despite the comparable dimensions and weight of the Chinese J20 Black Eagle and the F-22 raptor, "the T-50 has much shorter take-off and landing runs. Moreover, its on-board equipment has better specifications than its foreign equivalents."

India signed a preliminary design contract with Russia recently for the aircraft and is planning to induct around 250 of them starting from 2017.

Commenting on the flight tests schedule of the FGFA, Zelin said, "Tests are now taking place as planned in line with specific decisions.Over 100 flights have been performed and all the specifications obtained during the tests confirm T-50 project requirements."

"The tests involve three fixed-wing aircraft, and three more aircraft will arrive in the near future. All in all, the tests will involve 14 aircraft," he added.

Delays and challenges for Indo-Russian fighter

Seven years before its scheduled completion, the Ministry of Defence (MoD) has already announced a two-year delay in the Fifth Generation Fighter Aircraft (FGFA) India and Russia are to jointly develop.

Defence Minister A K Antony has been saying the FGFA would join the Indian Air Force by 2017. On Monday, his deputy, M M Pallam Raju, told Parliament, “The fifth generation aircraft is scheduled to be certified by 2019, following which the series production will start.”

The FGFA is the flagship of the Indo-Russian partnership. Both countries say it would be the world’s most advanced fighter. But interviews with Indian designers who have overseen the project suggest significant disquiet. There is apprehension the FGFA would significantly exceed its current $6 million budget, because this figure reflects the expenditure on just the basic aircraft. Crucial avionics systems would cost extra.



On the positive side, Indian designers say the FGFA project would provide invaluable experience in testing and certifying a heavy fighter aircraft that is bigger and more complex than the Tejas light combat aircraft (LCA), India’s foundational aerospace achievement.

The Russian and Indian air forces each plan to build about 250 FGFAs, at an estimated cost of $100 million per fighter. That adds up to $25 billion each, in addition to the development cost.

The FGFA’s precursor has already flown. In January 2010, Russian company Sukhoi test-flew a prototype called the PAK-FA, the acronym for Perspektivnyi Aviatsionnyi Kompleks Frontovoi Aviatsy (literally prospective aircraft complex of frontline aviation). Now, Hindustan Aeronautics Limited (HAL) will partner Sukhoi to transform the bare-bones PAK-FA into an FGFA that meets the Indian Air Force (IAF)’s requirements of stealth (near-invisibility to radar), super-cruise (supersonic cruising speed), networking (real-time digital links with other battlefield systems) and world-beating airborne radar that outranges enemy fighters.

But Sukhoi insists the PAK-FA already meets Russia’s requirements, says N C Agarwal, HAL’s design chief, who spearheaded the FGFA negotiations until his recent retirement. HAL worries Russia might ask India to pay extra for further development, particularly the avionics that transform a mere flying machine into a lethal weapons platform. That would leave the $6-billion budget in tatters.

The IAF clearly wants a top-of-the-line FGFA. According to Ashok Nayak, who spoke to Business Standard as HAL’s chairman before retiring last October, the IAF has specified 40-45 improvements that must be made to the PAK-FA. These have been formalised into an agreed list between Russia and India, the Tactical Technical Assignment.

A key IAF requirement is a ‘360-degree’ AESA (airborne electronically scanned active) radar, rather than the AESA radar that Russia developed. Either way, India would pay Russia extra: either in licence fee for the Russian radar; or hundreds of millions, perhaps billions, for developing a world-beating, 360-degree AESA radar.

Nor is the IAF clear on whether the FGFA should be a single-seat fighter like the PAK-FA, or a twin-seat aircraft like the Sukhoi-30MKI. A section of the IAF backs a single-seat fighter, while another prefers two pilots for flying and fighting a complex, networked fighter. During the ongoing preliminary design phase (PDP), for which India paid $295 million, the two sides would determine whether developing the PAK-FA into a twin-seat aircraft (inevitably more bulky) would reduce the FGFA’s stealth and performance unacceptably.

“The single-seat FGFA is essential for the IAF, and we will transform the Russian single-seat fighter into our single-seat version with a large component of Indian avionics. The twin-seat version will depend on the PDP conclusions,” says Nayak.

The PDP also requires Sukhoi to hand over design documentation to HAL, providing it a detailed insight into the design processes of the PAK-FA. Since India took years to decide to join the FGFA project, HAL missed out the design phase entirely.

The 18-month PDP, which terminates this year, will be followed by the ‘R&D phase’, which could take another seven years, says the HAL chairman. The FGFA would be designed in both countries. About 100 HAL engineers already operate from a facility in Bangalore. Another contingent would move to Russia to work in the Sukhoi design bureau.

“Our boys will learn the Russian language, their way of working, their design rules and their design norms. We are left-hand drive, while they are right-hand drive. The Russians say they would part with all these things,” says Nayak.

But the most valuable learning, say HAL executives, would take place during the FGFA’s flight-testing. “Unlike the basic design phase which we missed out on, we will actually gain experience during flight testing. This phase throws up dozens of problems, and we will participate in resolving these, including through design changes,” says Agarwal.

HAL designers also relish the FGFA’s specific challenges. For achieving stealth, its missiles, rockets and reconnaissance payloads are concealed in an internal bay under the wings. Before using these, a door slides open, exposing the weapon for use.

The Russians clearly believe HAL possesses useful capabilities, including the ability to design the AESA radar. Also attractive is India’s experience in composites.

“The LCA programme has generated a high level of expertise in composite materials within the National Aerospace Laboratory and some joint teams. The FGFA requires ‘higher modulus’ composites, which can withstand the 120-130 degree Centigrade temperatures that arise whilst flying at Mach 1.7 speeds,” says Agarwal.

Despite the continuing imponderables, HAL believes the FGFA project provides genuine technological skills, far more useful than licensed manufacture. Agarwal says, “We will pay some $6-7 billion to France for the licence to build the Rafale in HAL. In the FGFA project, a similar sum would bring in genuine design knowledge that will help us in the future.”

Fourth T-50 Stealth Fighter to Fly This Year




Sukhoi T-50 stealth fighter

Russia's United Aircraft Corporation (UAC) is to introduce a fourth Sukhoi T-50 stealth fighter into its test and development program this year, the company's President Mikhail Pogosyan said on Thursday.

"We are now testing three aircraft. A fourth will be brought in this year," he said.

Pogosyan had said earlier this year that the firm would introduce a fourth aircraft into the test program but did not disclose when.

The first production standard T-50 is due to enter service with the Russian Air Force by 2015, and the first evaluation example by 2013. The service plans to acquire 60 of the fifth-generation fighters.

The T-50, also known as project PAK-FA, first flew on January 29, 2011 and was first publicly revealed at the Moscow Air Show in August that year. India will also acquire an advanced fighter aircraft based on the T-50.

Seulement 60 avions ? Quel serait l’intérêt pour la Russie de développer un avion "aussi avancé" pour n'en produire qu'une soixantaine ? Pour un premier achat peu être ? Je ne me suis pas beaucoup renseigné sur le sujet mais ça m'étonne. Il me semble qu'ils en avaient prévu plus de 200 à l'origine, et qu'en ajoutant les avions indiens on arrivaient à beaucoup plus.

a elle seul l'inde en veux 200 mais en version biplace et construit localement.
les russes en veulent aussi plus de 200 et il y a plusieurs marchés Export comme l'Algerie, malaysie, indonesie, venezuela

La Russie ne va pas exporter le PAK-FA prochainement.
Il faut attendre au moins une dizaine d'année avant de le voir en service en Algérie, Venezuela, ou autre.

Il sera surement produit en série car il est planifié pour remplacer les MiG-29 et Su-27 dans le rôle de supériorité aérienne.

Sukhoi Tests New Radar Array for 5th-Generation Fighter

Russia’s Sukhoi aircraft maker has started tests of a new onboard radar system for its 5th generation T-50 fighter jet, the company said on Wednesday.

The new X-band active phased array radar has been installed on the third prototype of the T-50 fighter and showed a stable and effective performance comparable with the most advanced existing radar systems.

The radar has been developed by the Moscow-based Tikhomirov Scientific Research Institute of Instrument Design using elements of nanotechnology.

It has an extended target acquisition range, works simultaneously in “air-to-air” and “air-to-ground” modes, allows attacking multiple targets, and provides electronic countermeasures capabilities.

The T-50, also known as project PAK-FA, first flew in January 2010 and was first publicly revealed at the Moscow Air Show in 2011.

At present, three T-50 prototypes are being tested under a PAK-FA test and development program while a fourth plane is expected to join the program this year.

The Russian Defense Ministry is planning to purchase the first 10 evaluation example aircraft after 2012 and then 60 production standard aircraft after 2015.

Sukhoï teste le nouveau radar de son T-50

Le 09/08/2012 à 14:07 | Par Léo Barnier

Le T-50 a enfin débuté les essais en vol de son radar. La nouvelle a été communiquée par Sukhoï, ce jeudi 9 août, qui n'a pas précisé quand ceux-ci avaient commencé, ni leur durée. C'est le troisième prototype du chasseur de cinquième génération russe, désigné T-50-3, qui est en charge de la conduite des tests. Il est doté d'un système radar à balayage électronique actif Sh121, développé par l'électronicien russe Tikhomirov NIIP.


Sukhoï évoque pour l'instant une antenne unique, il s'agit donc très probablement de l'antenne N036-01-1, en bande X, placée dans la pointe avant du T-50. Elle est composée de 1 522 modules d'émission-réception à l'arséniure de gallium. De forme ovale (90 × 70 cm), elle est inclinée de 15° vers le haut (cf. photo).



A terme le T-50-3 recevra le système radar Sh121 complet, qui comprend également deux antennes de pointe avant latérales en bande X (N036B) et deux antennes en bande L implantées dans les bords d'attaque de voilure (N036L). Les antennes N036, en bande X comme en bande L, ont été développées à partir du programme AFAR, mené par Tikhomirov NIIP à partir du début des années 2000.

Sukhoï indique avoir déjà testé les modes "air-air" et "air-sol" du radar, au cours des essais au sol comme en vol. Selon son communiqué, "les premières expérimentations ont montré des performances stables et concluantes, comparables aux systèmes radar les plus avancés". Il a donc confirmé la poursuite du développement du Sh121.

Le constructeur russe a aussi indiqué que les tests des canaux optiques avaient débuté. Ce qui fait probablement référence à la suite optronique Atoll, développée par la société UOMZ, dont deux détecteurs d’alerte 101KS-U doivent équiper le T-50-3, sous le nez et sur la pointe arrière de l'avion.

Le T-50-3 est le premier exemplaire de l'appareil à recevoir un radar. Les deux premiers prototypes, destinés à ouvrir le domaine de vol, en sont dépourvus et se contentent d'un radôme métallique vide. Le T-50 est développé dans le cadre du programme étatique russe PAK-FA.

Chasseur russe de 5e génération: la version export produite en série d'ici 2020



20:46 10/10/2012
NEW DELHI, 10 octobre - RIA Novosti

La Russie lancera la production en série de la version export du chasseur de 5e génération Sukhoi T-50 (PAK-FA) d'ici 2020, a annoncé mercredi à New Delhi le ministre russe de la Défense Anatoli Serdioukov.

"Les ministères russe et indien de la Défense ont adopté des instructions techniques de production de l'avion. Nous envisageons de lancer la production en série de cet avion d'ici 2020 (…). Les deux pays ont déjà réglé nombre de questions administratives et se sont mis d'accord sur les caractéristiques de la version destinée à l'exportation", a indiqué M.Serdioukov à l'issue d'une réunion de la commission intergouvernementale russo-indienne.

Le commandant en chef de l'Armée de l'air russe Victor Bondarev a récemment annoncé que le T-50 (PAK-FA) serait livré à l'armée russe en 2016, après avoir passé des tests au Centre des essais en vol du ministère russe de la Défense à Akhtoubinsk (région d'Astrakhan) en 2014 et 2015.

Le T-50 est un chasseur de 5e génération doté d'un radar unique à balayage électronique actif, ayant une faible signature radar et thermique, une vitesse de croisière supersonique et une haute intégration des systèmes de commande. Il s'agit d'un appareil tactique alliant les caractéristiques d'un avion de frappe et d'un chasseur classique. L'avion est conçu pour remplacer les MIG-29 et les Su-27 en service dans l'armée russe. Le T-50 est développé en Russie depuis les années 1990.

Le premier décollage du chasseur T-50 remonte au 29 janvier 2010. L'avion a été présenté pour la première fois au public le 17 août 2011, lors du Salon aérospatial MAKS-2011 à Joukovski, dans la région de Moscou.
