Su-57 PAK-FA - Chasseur Polyvalent de 5e Génération
Re: PAK FA - Chasseur polyvalent de 5e génération
PAK FA with 'Brahmos'
The PAK FA chief designer Alexander Davydenko said, that during development work, the fight between T-50 and F-22 was modeled with good outcome for T-50. He also informed that the new avionics, weapon systems are already exist but will appeared latter since the 1st prototype is not ready for actually weapon carrying. The 2015 as the end term for starting serial supply was confirmed too.
Most inportant he said, T-50 will be built together with India 'in parity principle 50 and 50%', and can be equipped with 'Brahmos' missiles. It's first official confirmation about possibility of 'Brahmos' installation on PAK FA/FGFA fighter. However, it's not clear whether these missiles would be installed internally or externally. Anyway, it can be 1-2 missiles only due to heavy weight of 'Brahmos' supersonic missile.

Re: PAK FA - Chasseur polyvalent de 5e génération
Short acceleration – 200 m only – and the take-off is done! Other aircrafts can do this only from carriers. However, the Russian 5th gen fighter has a number of features allow it to take-off from a short horizontal airstrip. The 5th gen engine effectively provides it.
Ilia Fedorov, the Supervising Director of NPO 'Saturn', deputy general director of the Russian 'United Engine-building Corporation' (UEBC) tells about the difference of t-50's engine:
- "It has different thrust, naturally different tuning control. The number of constructive differences allow better thrust with lower fuel consumption. And the most important – it has totally different system of control".
The new engine of NPO 'Saturn' for PAK FA is the evolution of an engine family marked by the index '117'. Its tests on 'Saturn's facility in Rybinsk can be seen on this video. It proved its characteristics on the 1st PAK FA prototype: the taking-off is very steep on the video.
Sergey Chemezov, the Director General of 'Rostechnology' state corporation (NPO 'Saturn' owner) says:
- "The engine allows long time supersonic fly without the afterburner. The thrust-vectoring is provided for better maneuverability".
The engine is the heart of a fighter, but the radar is its eyes and ears. And the navigation system is like a 'vestibular system'. All these indispensible features of 5th generation were developed together with the fighter itself.
Sergey Chemezov, the Director General of 'Rostechnology' state corporation (NPO 'Saturn' owner) says:
- "The sub-units of 'Rostechnology' Corp. are produced engines and different devices for different planes including of course - PAK FA. I think they produce about 70% in this class of parts".
The pilots notice with pride: even the first prototypes have almost serial avionics. They have 5 next years for elimination this 'allmost' by tests.
Boris Obnosov, Director General of 'Tactical Missiles Weapon' Corp., says:
- "The intensity of the tests had no examples even in USSR era. It due to the big numbers of devices (missiles) and shorten terms of development. As it was already declared by RuAF Commander General we are responsible to provide this plane as a weapon system".
It's not kind of 'demonstration aircraft' for an air-show, but the formidable universal weapon system: air-to-air, air-to-ground, short, medium and long range. R-73 – is the smallest but formidable air-to-air missiles. It's in modernization. It's a 'digital' missile like all T-50's weapon systems.
Boris Obnosov, Director General of 'Tactical Missiles Weapon' Corp., says:
- "The obligate condition for 5th gen fighters like F-22 and PAK FA as well is intra-fuselage placement of missiles. It's provided for RCS reduction".
The American F-22 'Raptor' was considered invincible till T-50 appearance. F-22's constructive 'ideology' is stealthiness against ground-based radars. The 'Sukhoi's fighter 'ideology': to spot 'Raptor' early and to overwhelm it in the short range fighting. In fighting stealth vs. stealth the better radar will decide the winner.
Vladimir Zagorodny, Constructor General, the department Chief in NIIP 'Tikhomirov' says:
- "We will be able to counter these stealth fighters and even win them in some duel situations".
Vladimir Zagorodny shows his team 'baby': the radar for the new fighter. Due to secrecy the door here is usually closed for press, but they did exception for us. The AESA has more then 1500 MMICs. This radar is named AFAR in Russian: the active phased antenna array. Five AESA radars over all airframe will detect the targets in any direction.
Vladimir Zagorodny, Constructor General, the department Chief in NIIP 'Tikhomirov' says:
- "I didn’t see such technology in 'Raptor' or F-35".
All T-50's electronics is netted in a unified intellectual complex, able to prompt pilot what to do in the fly. Indeed, the 5th gen fighter – is sometimes called 'flying computer'. The part of the pilot work will be done by the computer.
Andrey Tyulin, Director General of 'Aviapriborostroyenie' concern, says:
- "The avionics allow high precision flying to the needed point, successful using high precision weapon, and aircraft precise positioning in the air space".
Stealth technology means less IR emission and less metal in the airframe. Then, the engine blades must be hidden and the composites must be used broader.
Nikolay Vymornov, the Chief Technologist of NPK 'Composite' says:
- "In F-22 and F-35 the use of composites in airframe is not less, then 40%. We are sure, in our PAK FA fighter the use of composites will not fall of this number".
The new carbon-plastic composite was already developed specially for 5th gen fighters. The metal details are made with new technologies too. The plane will fly on critical and even super-critical fly regimes. So the special requirements for the materials are needed. It's OK now in Russia: our country is the biggest titan consructions supplier.
Sergey Chemezov, the Director General of 'Rostechnology' state corporation (NPO 'Saturn' owner) says:
- "The titan alloys (of T-50) are manufactured in VSMPO 'Avisma' – the world biggest titan alloys and titan products manufacturer".
The first flying prototype – is only a subject for testing. When T-50 appears in RuAF colors it probably will look rather different. However, the work done is not done in vain.

Re: PAK FA - Chasseur polyvalent de 5e génération
The Russian researchers go further for developing more advances compounds and technologies for an anti-radar covering. As it's well known, the airframe and the shipframe stealth geometry gives only a partial answer for the contemporary radar development. Only the centimeter and millimeter long radar waves are effectively deflected by such method while the L-band radars progress is remained the growing treat for military devices. Other complimentary methods are composite use and covering.
The usually used antiradar materials are the resins and paints with ferromagnetic. The new nano-metric anti-radar covering is much more light and stable. It's made with magneto-dielectric layering 2-80 nm thick on a high temperature-steady material. The radar-absorption is about 10 Db in 8-80 GHz diapason, i.e. lg (P1/P2) = 1, while P1 – is the incoming radar power and P2 – the reflected. By the formula with these materials the RCS can be reduced 10 times. Its relative mass is as 1 – 1.5 kg/m2. High resistance against climatic factors is provided. They have the one-layer structure instead of usually 5-6.
This new technology can be used not only for RCS reducing, but for side-lobe radiation reducing on the radars, raising their effectiveness. The military electronics can be defended from radio splashes and an unsanctioned communication access by this way. Personal isolation from the dangerous radar microwaves can be provided too by this method.
The potential of this technology allows creating ant-radar materials with working diapason of 1 – 300 GHz. The implementation of it on the 4th+ generation fighters' fleet could prolong its service while the 5th generation planes are yet to be produced or too costly for some customers.

Re: PAK FA - Chasseur polyvalent de 5e génération
Now it is clear, that in its airframe design the fighter is closer related to American F-23 prototype, than F-22 or JSF, but with bigger internal payload bay. However, it has unrepeatable impress of Sukhoi design house, clearly looking as a thoroughbred Su-linage. According to the most reliable estimations, T-50 has 10 internal and 2 additional external hardpoints on the wings (the 'mystery' triangle thickening under the wings). With this great payload capability and much space for the fuel T-50 can became a true military 'workhorse' of the future battlefield!
From relatively unexpected moments the controlled LCA-like LERX must be noted. It demonstrates the designers' assertiveness (if not hardball) in field of the super-maneuverability. With currently installed 14.5 t thrust 'izdelie 117' and futuristic 17,2 t thrust Al-41F engine the plane can take off from a 300-400 m horizontal airfield or even a highway. Also, the multiplicity of controlled aerodynamic surfaces, which make precision landing easier, is an indication about intention to use the plane in the future as a carrier-based platform . However, the capability of the aircraft to land on Vikramaditya-size carrier (40 kt) is not yet clear.
The nozzles was designed round, as expected, which provoked speculations about problem in IR and radar stealthness from rear hemisphere. However, the program chief has explained early, that IR and radar observability reduction was achieved not worse than on American 5th gen. fighters, but in different way. The 1st prototype has no TVSs but it's certainly formulated as a part of the program and already developed by 'Klimov'.
The triangle form of the wings is optimized for supersonic maneurability, and indirectly confirms the supercruise capability of the aircraft. On other hand the cross-section of the nose-cone is not so flattened, as was predicted according to flattened AESA form.
As Putin's deputy has officially declared, the prototype already has an installed data link which allows it the battlefield communication. According to him the new 5th gen. avionics, the 'electronic pilot', allow to pilot concentrate its efforts on the battle instead of the piloting. In addition: it has an advanced HOTAS type control. However, Russian PM Putin itself said after the fly, that the designers 'have much to work' on the fighter's weapon and engine. The program is described by the cabinet as the 'first priority military program', and its 100% financing will continue despite the world financial turmoil.
A somewhere disappointing is the old fashion look of the cockpit, but this can relatively easy be improved till entering serial production. The information about the tender for a frame-less cockpit is already published. However, the riveting is relatively smooth and minimalistic comparing to JSF for example. The additional bulk RCS reduction in different diapasons will be achieved by new Russian nano-structural coating technology.
Signal and mission processor: based on the new fully Russian 6-core VLIW chip 'Elbrus-2S' based on 2-scalar cores ('Elbrus-S') + 4 signal cores (Elvees) . 40 MFlops. The fighter will have at least 4 'Elbrus'2S' chips in its processor unit.
The production is planned to be started till 2013. Then, according to the PM's publicly announced decision, the first batch of fighters has to come to the practice center in 2013, and in 2015 the fighters have to be on service.
The former Sukhoi's chief (now working with 'MiG' in UAC directorate) and the 'father' of PAK FA program Mikhail Pogosyan said after the flight, that the United Air-building Corporation (UAC) will follow to work with the Indian counterparts on this program and he is sure, that this product will catch the world market too.
I personally estimate the fighter (in single and two-sitter configuration) jointly produced in Russia and India can be exported to Russian and Indian friendly countries around the world. The list of the countries who can afford T-50, includes in the first place those, who already use Soviet/Russian fighters in AF and want generation upgrade. It could be Belorussia, Kazakhstan, Venezuela, Algeria, Malaysia, Libya and in some circumstances – Iran. The second line, if economically improved, the follow states could become T-50's customers too: Vietnam, Myanmar, Indonesia, Syria, Serbia and even Ukraine (if more realistic president will be elected). However, I think, China has zero chance to be allowed for T-50 import for obvious reasons.
Other problem is the unfair competition, sometimes accompanied by huge kickbacks. The natural competitors of Indo-Russian T-50 on the world market is JSF and the 4+ gen eurojets. If aggressive marketing of those planes succeeds, the prospects of PAK-FA/FGFA program may be worse for simple reason of fund devastation. I'm not sure, how this fact is reflected in political consciousness in two countries. Methinks both countries must concentrate maximum efforts on their most advanced fighter program instead supporting third part foreign competitors by massive purchases.

Re: PAK FA - Chasseur polyvalent de 5e génération
une petite traduction pour les non anglophones
Moscou, le troisième prototype de l’avion de cinquième génération développé par le constructeur Sukhoi à effectué son premier vol cette semaine sur le site de Komsomolsk. Au commande du T-50-3 (PAK FA), le pilote d’essais Sergey Bogdan.
Le T-50-3 (PAK FA) a volé durant un peu plus d’une heure. Le vol a été un succès, en pleine conformité avec le plan de vol. La stabilité est excellente et l’aéronef s'est avéré bon dans toutes les phases du programme de vol prévu. Le pilote a confirmé un fonctionnement fiable de tous les systèmes et composants.
Tests des senseurs :
Ce troisième prototype va servir à tester l’ensemble des senseurs qui équiperont les appareils de série, avec en pointe le nouveau radar SH-121 développé par l’institut Tikhomirov NIIP. Ce radar à antenne active (AESA) dispose de 1.500 module T/R à l’arséniure de gallium fonctionnant en bande X. En plus de l’antenne dans le nez de l’avion, le système disposera de deux autres plus petites sur les côtés et deux autres plus grandes en bande L sur les bords d’attaques des ailes.
L’ambitieux système est complété par un IRST optique avec mode infrarouge dérivé du MCO-35M qui est actuellement monté sur le Sukhoi SU-35s. De son côté, le partenaire Indien du T-50, Hindustan Aeronautics Limited a fournit le système de navigation et l'ordinateur de mission de pré-série qui sera également testé.
L’avion de cinquième génération :
Par rapport aux précédentes générations d’avion, le FA PAK possède plusieurs caractéristiques uniques, combinant les fonctions d'un avion d'attaque et d’intercepteur. L'avion est équipé d'une avionique de cinquième génération avec fonctions intégrées dites «pilote électronique". Cet équipement permet de réduire la charge de travail du pilote et l'aide à se concentrer sur des objectifs tactiques. L'équipement à bord du nouvel avion permet l'échange de données (Link16) en temps réel avec les systèmes de contrôle au sol et d'autres aéronefs. Le PAK-FA est fait de matériaux composites avec des technologies innovantes. Son design aérodynamique et les mesures visant à réduire la visibilité du moteur afin de fournir une très faible signature radar. La capacité de «voir» combinée des trois radars et des optiques améliore considérablement l'efficacité au combat sur des cibles aériennes et terrestres, à tout moment, dans des conditions météorologiques à la fois bonnes et défavorables.
Rappel :
En développement depuis les années 90, le PAK FA devrait entrer en service dans l'aviation russe à partir de 2015. Il doit remplacer les Mig-29 et Su-27. L'Inde est également partenaire de ce programme. Cet appareil devrait d’ailleurs à l’avenir former l’épine dorsale de l’Indian Air Force (IAF). Le coût du développement du T-50 partagé entre les deux pays, devrait être de 6 à 7 milliards d’euros. Le coût d’un appareil devrait dépasser les 70 millions d’euros.
En comparaison des Sukhoi Su-30 actuels, la signature radar devrait se situer à 0,5 mètres carré par rapport aux 20 mètres carrés de celui-ci !

Sukhoi Tests New Radar Array for 5th-Generation Fighter
http://en.rian.ru/mlitary_news/20120808/175068051.htmlRussia’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.
