Le Su-35 : un chasseur à un pas de la 5e génération

publié le lundi 24 septembre 2007


Le chasseur Su-35 était peut-être la nouveauté la plus attendue au récent Salon aérospatial MAKS-2007 près de Moscou. Comme prévu, il était exposé sur une aire de stationnement, en position statique. Mais, prochainement, après quelques mises au point au sol, il effectuera son premier vol. Déjà, deux Su-35 expérimentaux sont assemblés à l’usine Sukhoi de Komsomolsk-sur-l’Amour, en Extrême-Orient russe. Fin 2007, ces appareils aborderont un programme d’essais en vol. Mikhaïl Pogossian, directeur général de Sukhoi, affirme que le nouvel avion russe est déjà attendu à l’étranger. Des négociations sur la livraison du chasseur sont en cours avec plusieurs pays.

En fait, ce chasseur est connu de nom depuis suffisamment longtemps. Il y a une quinzaine d’années, un Su-27M avait été présenté à différents salons aéronautiques. Depuis, l’appareil a subi une modernisation en profondeur. Quelles sont les nouveautés ?

D’abord, le Su-35 est doté de nouveaux moteurs. Sur le plan de leur conception, ceux-ci, des AL-31FP, sont un développement des AL-31F construits en série avec recours aux technologies dites de cinquième génération. L’apparition d’une tuyère tournante, de même que la possibilité d’une modification différentielle automatique de la poussée de ses deux moteurs (commande différentielle de la poussée) garantissent un pilotage de l’avion dans tous les plans. Y compris à petites vitesses ou à des vitesses proches de zéro. Conditions dans lesquelles les organes aérodynamiques de commande cessent, traditionnellement, d’être efficaces. Si nécessaire, le système de direction de la poussée vectorielle peut être entièrement coupé, avec fixation des tuyères en position neutre.

Le nouveau radar à réseau actif à phases (FAR) constitue la base du système de commande des armements du Su-35. Ses performances, en termes de portée et de nombre de cibles suivies, sont uniques. C’est un développement du radar Bars. Le FAR assure la scanographie du faisceau, aussi bien en azimuts qu’en angles de site. Pour améliorer la visibilité dans le plan horizontal, l’antenne tournante est mécaniquement entraînée en azimut, au moyen d’un gyro-actionneur. En régime air-air, ce radar est susceptible de détecter, sur des caps de face et à des distances allant de 350 à 400 km, et aussi de suivre (sans interrompre l’observation de l’environnement) jusqu’à 30 cibles, ainsi que de tirer sur huit d’entre elles. Des cibles ponctuelles ayant des surfaces de réflexion d’un centième de mètre carré, sont détectées à une portée de 90 km. C’est une performance unique pour tout radar d’aviation.
Un radar optoélectronique d’une nouvelle conception intégrant un goniomètre infrarouge, un télémètre-localisateur laser et une chaîne de télévision assurent de nouvelles possibilités dans la commande des armements du Su-35.

Côté armements, ceux du Su-35 représentent, outre des missiles air-air connus à portée moyenne à têtes autodirectrices, à radar ou à infrarouge, actives et semi-actives, et des missiles de combat à courte portée (34 unités au total), cinq nouveaux missiles à grande portée. La nomenclature des armements guidés de la classe air-sol comprend 25 missiles anti-bâtiment et antiradar, à grande et moyenne portée. Dont le système Klab et un missile lourd à grande portée de type d’Iakhont.

Pour ce qui est des bombes d’aviation à guidage télévisuel, laser et satellite, le Su-35 ne se distingue pratiquement en rien des Su-30MK actuels. Mais, en principe, le nouveau chasseur pourrait accueillir de nouveaux modèles. L’efficacité des bombes d’aviation guidées est garantie par un viseur laser et télévisuel. Celui-ci est disposé dans un conteneur optoélectronique suspendu. Ce poste détecte, suit, mesure des distances, et éclaire au laser des cibles au sol.


La masse d’armements maximale d’un Su-35 est de 8.000 kg. Celle-ci est répartie entre les douze points de suspension. Equipé de moteurs à poussée vectorielle et d’un complexe électronique perfectionné de bord, le Su-35 dépasse notablement en performances son « ancêtre », le Su-27M. A l’opposé du Su-30, proposé sur les marchés internationaux, il est mieux adapté à un combat aérien tournoyant, notamment grâce à sa masse moins importante.
« A partir de 2010, nous nous projetons de commencer les ventes du Su-35 à l’étranger », a annoncé le directeur général de Sukhoi, Mikhaïl Pogossian. Le nouveau chasseur doit occuper une niche entre les Su-30MK actuels et ses différentes versions et les appareils, encore en développement, de cinquième génération. Le Su-35 est lui un avion de génération dite 4++, mais dont la conception fait largement appel à des technologies de cinquième génération, estime-t-on à Sukhoi. Entre 2009 et 2015, ces technologies doivent assurer au Su-35 des avantages indiscutables par rapport aux autres chasseurs multirôles de quatrième génération.

le radar: Irbis-E

Citation :

The Irbis, also known as Irbis-E, is an advanced X-band multi-mode phased array radar system developed by Tikhomirov NIIP for the Su-35 multi-purpose fighter aircraft. NIIP developed the new radar based on the Bars radar system provided to Su-30MKI/MKM/MKA aircraft. Its development started in 2004 and the first radar prototype entered flight tests onboard an Su-30MK2 aircraft acting as a test bed in early 2007. The resulting radar system will provide air-to-air, air-to-sea and air-to-ground (ground mapping, Doppler beam sharpening and Synthetic Aperture radar modes) modes with improved performance in intense clutter environments compared to Bars. In addition, Irbis has been designed to detect low- and super-low-observable/stealth airborne threats.

The Irbis multifunctional radar employs a 900mm passive phased array antenna mounted on a hydraulic actuator. With electronically steering, it can scan sectors of 60 degrees in both azimuth and elevation. Using the hydraulic actuator (mechanical steering), the azimuth coverage boosts to 120 degrees. It can detect and track up to 30 airborne targets with a Radar Cross Section (RCS) of three square meters at ranges of 400 kilometers using track-while-scan mode while engaging two targets with semi-active radar homing missiles or up to eight targets with active radar homing missiles. In the air-to-surface mode the Irbis provides clues allowing to attack a surface target with precision-guided weapons while scanning the horizon searching for airborne threats that can be engaged using active radar homing missiles.

Tikhomirov NIIP has provided the ability to spot super-low-observable targets with RCS = 0.01 square meters at ranges out to 90 kilometers. This capability might allow Su-35 aircraft to engage cruise missiles and unmanned aerial vehicles as well as fifth generation stealth fighter aircrafts such as the F/A-22 Raptor and F-35 Lightning II. NIIP and GRPZ will take care of the Irbis production with the first radar system slated for installation on the Su-35 in August 2007.

Su-35BM/T-10BM : The last Flanker

Introduction :

Su-35BM will be the last developed Flanker. An final upgrade, final variant. Actually, the designation is quite confusing, since Su-35 already exists in Russian Air Force. Su-35 was the export designation for upgraded Su-27, called Su-27M, internal Sukhoi designation T-10M. Su-27M gave baseline Flanker new avionics, as well as precision air-to-ground capability. Only five of these are in service with VVS (Russian Air Force), with 237th regiment based at Kubinka Air Base. VVS chose another path instead; to incorporate technologies tested in Su-35/T-10M, together with those of Su-30MK, into an standard upgrade project for the baseline Flanker, the Su-27SM. The Su-35 designation was also used for Su-37, dubbed as “Terminator”. Aircraft was a testbed for 2D thrust-vectoring engines, mounted on Su-35/T-10M.


The new Su-35BM is going to fill the interim gap between standard 4+ generation Su-27SM in service today, and PAK-FA, 5th generation fighter in developement stage. Thus, Su-35BM is designated as 4++ generation fighter, together with new MiG-35. Official first flight will commence late this year, Sukhoi officialy stated that year 2007 is the ending year of all work on Su-35BM. After MAKS 2007, Su-35BM will be put on state trials. The aircraft should be ordered by VVS, after all, they’re the ones who supported the initial beggining of work on the BM, after successful Su-27SM program.

The most important Su-35BM/T-10BM characteristics are : supreme flight performance (superagility), long range information targeting systems, jam-proof datalinks for squadron or ground control operations, high performance short, medium and long range missiles of both anti-air and anti-ground type, carried externally on fourteen hardpoints, sophisticated EW/ECM/ER systems, radar cross-section reduction, high-power sensors with adequate computing power and sensory fusion technique, cockpit with large LCD multi-function displays, and an in-flight refuelling probe.

Unlike Su-37, which was seen as remarkable aircraft by aerospace community, Su-35BM will have all Russian systems. Su-37 had it’s cockpit systems imported from French Sextant/Thales.

Airframe :

Su-35BM is more alike standard Su-27S, than Su-35/T-10M. It has no canards, has smaller fins, tailcone is smaller than those found on T-10M. High-lift surfaces are larger, big flaperons occupying complete wing trailing edge. Airframe structure is more “refined”, with usage of RAM coating and new all-composites material. Latter is said to grant 20% of weight reduction and an RCS signature suppression. Su-35BM also has larger air intakes.

Powerplant :

Engines that were planned for T-10BM are Saturn AL-41F1, with supercruise capability, rated at 15 metric tons of thrust each. This family of engines will power PAK-FA too, and are going to power Su-34 Fullback long range strike aircraft. The AL-41 series was built to feed power-hungry aircraft such as MiG’s MFI (1.42/1.44), and S-37/Su-47 Berkut. It was stated that first versions of these engines powered the MFI, but, recent statements from NPO Saturn pointed out, that engines won’t be ready for the first preproduction versions of PAK-FA. Thus, it’s viable to concur that Su-35BM won’t have it’s first flight with AL-41F1. To note : the MFI has flown on AL-31’s, while the Berkut was fitted with D-30F-6 engines, powerplant from MiG-31.

However, NPO Saturn managed to develop heavily upgraded AL-31F engines, and designated them AL-41F1A, or article 117S. The designation of AL-41(X) notes that thrust is closer to projected AL-41F series, but the AL-41F1A’s feature old, refubrished core. The AL-41F’s will have all-new core.

AL-41F1A are equipeed with three-dimensional thrust vectoring nozzles, too, so both of Russian 4++ generation aircraft will be 3D TVC capable, if we count the fact that Morskaya Osa engines can be upgraded with all-axis nozzles. As it’s stated on official sites, AL-41F1A’s have 14.5 tons of thrust each, that means 29 tons of thrust for Su-35BM. Since some early sources claimed that airframe material enhancement reduced Su-35BM weight by 20%, aircraft could have an greatly increased thrust-to-weight ratio, ensuring superb combat and flight performance.

Le radar et les capteurs du Su-35BM:

Sensors and avionics :

Main radar system for the Su-35BM is the Tikhomirov NIIP Irbis-E (N035E). While it’s pointed out that this will be the radar model used on Su-35BM, it’s also probable that Su-35BM could fly with Phazotron NIIR radar, the Sokol III (N031 Zhuk-MSFE). Given the latest achievements on the field of AESA technology by Phazotron, that are already visible in form of complete systems found on the other Russian 4++ gen aircraft, MiG-35, Su-35BM could be equipped with an derivative of current Phazotron AESA models. However, Irbis is marked as the number one option for the radar system.

Tikhomirov NIIP Irbis-E radar uses electronically scanned array (ESA). It’s a multifunctional radar system, working in X-band, holded on two-axis hydraulic drive. Radar uses EKVS-E BTsVM Solo35 computing system. The Irbis-E can track 30 different targets, while retaining continous airspace scan, eg. track-while-scan mode. The fire control system can simultaneously guide two semi-active radar guided missiles. If used in conjuction with active radar guided missiles, this number is eight. In air to surface operations, radar is capable of mapping land and sea targets, and detection of targets in real-beam, Doppler, and SAR modes. Four ground targets can be tracked at the same time, while two can be attacked at the same time, too. Since Irbis-E has enormeous power output, up to 20 kilowatts, it can detect an “standard” target (RCS at 3 square meters) 400 kilometers away. Normally, that figure is given for head-on aspect, in tail-on aspect it drops down to 150 km. Stealth targets (RCS at 0.01 square meters) can be detected at 90 km range. Irbis-E is also capable of target identification, and can conduct simultaneous air-to-air and air-to-ground operations.

Su-35BM also has rearward radar system, to locate and track targets behind aircraft. Rear radar is located in tailcone. It’s still not known what system is going to use; Tikhomirov NIIP suggested it’s Osa type ESA radar for this task, but has also revealed it’s work on active-array radars that could fill this task, too. That information was given by NIIP to the public two years ago. The rear radar system is not something new for the Russian design bureaus; Su-35/T-10M features Phazotron N012 in the tailcone, MiG’s 1.42/1.44 MFI featured Phazotron N015, and the Su-34 Fullback features Leninets V005 tailcone radar system.

As every Russian 4th gen fighter has optronic infrared search and track system, Su-35BM will naturally feature that too. OLS-35 can track four different IR signatures at once. Maximum detection range for tail-on aspect is 90 km, and for head-on 50 km. The laser rangefinder can measure distance up to 20 km against aerial targets, and up to 30 km against ground based targets.

Electronic warfare system, the KNIRTI L175M Khibiny-M, is capable of accurate detection of the threats, threat coordinate mapping, and it’s also responsible for jamming signal generation and emmision replication/imitation, via wing-tip carried pods. The system has a separate display in the Su-35BM cockpit. The L175M, together with frontal and back radars and optronic complex is hooked up to “sensory fusion” package. Khibiny can also provide guidance for passive-radiation guided missiles, such as R-27EP and the new long-range type of AAM. Su-35BM also features approx. 150 aerials on it’s airframe. Apart from standard RWR (radar warning receiever), Su-35BM also has laser emission warning system, MAWS (missile approach warning system), and standard chaff / flare dispenser.

Powerful computer system will control all those sensory elements, giving information to the pilot in unique interface; via the two large LCD MFD’s found in cockpit, and shown in pilot’s helmet mounted display as well. Cockpit is summarized in MAK-35 system; two 22.5×30 cm AMLCD’s, IKSh-1M widescreen HUD, and one back-up multifunctional display. The nav / attack functions are the responsibilty of KRNPO-35, and the plane is fitted with laser-gyro system, LINS-2000.

The aircraft features inertial / sattelite navigation systems, radio navigation system, digital maps, optical fiber and digital communication multiplex comm systems. The comm system has two UHF/VHF radios, Link-16 capacity, and encryption capability. FBW has quadruple redundancy, and the engines support full authority digital engine control, FADEC.

Weapons :

Su-35BM, as an true multirole fighter, will have both air-to-air, air-to-ground, and anti-ship weaponry. Whole current pallete of A2G precision missiles and bombs will be supported on Su-35BM. Regarding air-to-air, the aircraft has an Archer, Alamo, and Adder family capability (R-73, R-27, R-77). Su-35BM will also be able to launch ultra-long range active radar missiles. The type of this weapon shown on the Su-35BM model was Novator KS-172S-1 AAM. The same missile has been presented on the displayed Su-35BM at MAKS 2007 airshow. The KS-172S-1 has an engagement range over 300 kilometers, can be used against any kind of aircraft flying from 3 meters altitude to 30 kilometers altitude, up to 4000 kilometers per hour of speed, and up to 12G. The only thing that’s confirmed is that Su-35BM will have ultralong range radar missile engagement capability; KS-172S-1 has not been asured. The other ULR AAM in Russian developement is Vympel K-37/R-37M. It’s an upgrade of MiG-31M’s R-37 missile, which has been sucessfully tested against targets 300 kilometers away.

Other Vympel’s designs are not confirmed either; such as ramjet, thermal, or antiradiation variant of R-77. This capability could be easily added at some future point. Vympel also stated that it has finished working on the upgraded variant of antiradiation R-27P. Since L175M is chosen for the standard electronic warfare module for all new Russian aircraft, R-27P could be connected to work in conjuction with Su-35BM’s EW unit. Both short and long burn variants of the antiradiation R-27, eg. the 27P and the 27EP, are on the payload list.

The misterious unspecified long-range anti-ground, anti-ship and anti-radar missiles are still a matter of debate, but several sources indicate that GRAU-coded 3M14AE and 3M54AE missiles are the unspecified weapons. Both missiles are produced by NPO Novator, and Sukhoi has a long tradition of partnership with this design bureau; this raises the issue of long-range AAM too, since Sukhoi is clearly pushing the Novator’s KS-172S-1 design, while the VVS wants Vympel’s R-37M for MiG-31 deep modernization variant. In any case, Russia won’t use two similiar types of AAM’s in the same time period, so the R-72 could be used for export, while the R-37M would be used on domestic version of Su-35BM.

3M14AE and 3M54AE are the missiles from “Kalibr” system, developed from naval “Club” system. The first is LACM, while the other is standard anti-ship missile. The unspecified anti-radar missile could turn up as new Raduga X-58UShE. It works in wide-band regime, and has a maximum range of 200 km. The sole-carried large ASM/AGM is suspected to be Yakhont-M, GRAU coded 3M55A. Yakhont-M is the upgraded export variant of P-800 Onyx missile. Original Onyx has the range of 300 km.

Su-35BM is also fitted with standard 30mm gun of Flanker family; Gryazev-Shipunov GSh-301.

Armée de l'air russe: essais réussis du deuxième Su-35

17:51 | 02/ 10/ 2008



MOSCOU, 2 octobre - RIA Novosti. Sukhoi a lancé les essais du deuxième exemplaire de son nouveau chasseur polyvalent Su-35, a annoncé jeudi le constructeur aéronautique russe.

"Le deuxième exemplaire du Su-35 a effectué un vol d'une heure pendant lequel son groupe propulseur et son système de direction ont été testés à des régimes différents. Les performances de stabilité et de maneouvrabilité de l'avion et de son groupe propulseur ont été vérifiées. Le fonctionnement du groupe propulseur, des systèmes et des équipements de l'avion n'a fait l'objet d'aucune remarque", lit-on dans le communiqué de Sukhoi.

L'avion était piloté par Sergueï Bogdan, qui était aux commandes du premier Su-35 le 19 février. "Depuis, plus d'une quarantaine de vol ont confirmé les performances de l'appareil", rappelle le service de presse de Sukhoi.

"La participation aux essais du deuxième appareil permettra d'accélérer la réalisation du programme et de garantir les livraisons en série des Su-35 aux clients russes et étrangers en 2011", souligne le communiqué.

Le Su-35 est un chasseur polyvalent supermanoeuvrable utilisant des technologies de génération 4+++. La masse au décollage de l'avion est de 25,7 tonnes, sa charge de combat maximale disposée sur 12 points de suspension de 8 tonnes, le groupe propulseur de l'appareil compte deux moteurs à vecteur de traction orientable. Développant une vitesse maximale de 3.500 km à l'heure , le chasseur peut voler à 17 km d'altitude et son rayon d'action est de 3.200 km, sans réservoirs suspendus.

Le chasseur est équipé d'une nouvelle avionique, d'un radar multimode capable de suivre jusqu'à 30 cibles aériennes et de tirer sur 8 d'entre elles à la fois, notamment au missile vers l'arrière.

Outre les armements modernes déjà utilisés par le Su-30MK, le Su-35 devra accueillir de nouveaux types d'armes guidées air-air et air-sol, y compris à grand rayon d'action.

1000 Km de trop !

oui c'est exagéré! c'est la raison pour laquelle j'ai mis la phrase en relief.

il faut pas trop se fier à rianovotsi, ils ne sont pas independant du tout, sinon la bête est superbe, je sais pas si on risque de la voir chez nos voisins de l'est bientot.

au devellopement dutyphoon les concepteur on pris comme "avions russe a battre" le su35, du moin ses caracteristique!!!! donc je me mefie un peu du matos russe sur le papier il son solide mais leur homologue occidentaux son un cran au dessu je pense ( typhoon,rafale,f35,f22)

rien de nouveau chez les russes

Russian Su-35 fighter jet prototype destroyed during testing

KHABAROVSK, April 27 (RIA Novosti) - A prototype of the advanced Su-35 Flanker multi-role fighter plane burst into flames during take-off procedures at a testing ground in Russia's Far East, a spokesman for the Komsomolsk-on-Amur aircraft plant said on Monday.

"The accident occurred at 09.55 Moscow time [05.55 GMT] on Sunday at the Dzemgi airfield during the Su-35 prototype's take-off," Vitaly Tyulkin said, adding that the pilot ejected safely.

"We will announce the details of the accident later in the day," he said.

Sources earlier said the accident could have been caused by a faulty fuel pump.

The aircraft was one of the three prototypes to test the new fighter, which has been billed as "4++ generation using fifth-generation technology."

The Sukhoi aircraft maker said in March that successful flight tests involving two prototypes had confirmed the earlier-announced timeframe for deliveries of the aircraft to Russian and foreign customers in 2011.

The company had planned to add a third prototype to the testing program in the second half of 2009, and to boost the current number of test flights to 150-160.

Su-35 fighter, powered by two 117S engines with thrust vectoring, combines high maneuverability and the capability to effectively engage several air targets simultaneously using both guided and unguided missiles and weapon systems.

The aircraft also features the new Irbis-E radar with a phased antenna array, which allows the pilot to detect and track up to 30 air targets, while simultaneously engaging up to eight targets.

It is equipped with a 30-mm cannon with 150 rounds, and can carry up to eight metric tons of combat payload on 12 external mounts.

Sukhoi plans to export at least 160 Su-35 fighters to several countries including India, Malaysia and Algeria

leur pompe à fuel ne fonctionne même pas et il veule faire un appareil de 5ème génération soit disant

Franchement, l'appellation "5e generation" est exagérée pour un developpement du Su-27! Sinon le F-15SE serait aussi de la 5e generation, mais bon, laissez-les se croire les plus forts alors que la moitié de la "grande Russie" creve la dalle!

les russes travaille t il a diminuer la SER de leur avions ou pas encore

parce que si c est pas le cas avec la famile SU (avions enormes:affraid: ), malgré leur perfs et leur manœuvrabilité impressionnantes, je donne pas cher de leur peau face au dernier joujoux occidentaux (EF2000,F15SG,f22,F35...etc)

Su-35 Suffers A Setback

May 1, 2009: One of the two prototypes of the Russian Su-35 fifth generation fighter crashed on takeoff on April 26th. The cause was a problem with one of the two engines. A third prototype is already under construction. Russia had hoped to have the destroyed prototype fly over the May Day parade in Moscow on May 1st. The crash is really bad PR, since one of the consistent shortcomings of Russian warplanes has been the unreliable engines.

Last July, this long promised Russian answer to the F-22, the Su-35, had its first flight. In late 2007, the Russian Air Force showed off the first of two flyable prototypes. It was three years ago, that Russia announced its long promised Su-35 fighter, was back in development again.

The Su-35 is an enhanced Su-30 (itself a development of the Cold War era Su-27), and has been in development since the 1990s. At one point, it was called the Su-37, but the name was changed back to Su-35. Since the 1990s, time, many Su-35 prototypes were built, and apparently no two were identical. There were many disagreements over what direction the development should take, and by the late 1990s, the project was basically suspended for lack of funding.

The Russians want to sell Su-35s to China, India and other foreign customers, and this opportunity turned the cash flow back on. Apparently Russia now has the billions of dollars it will take to carry out the Su-35 development program. India has become a partner, contributing cash, technology and manufacturing capability.

The Su-35 is a 34 ton fighter that is more maneuverable than the original, 33 ton, Su-27, and has much better electronics. It can cruise at above the speed of sound. It also costs at least fifty percent more than the Su-27. That would be some $60 million (for a barebones model), about what a top-of-the-line F-16 costs. The Su-27 was originally developed to match the F-15, which is larger than the single engine F-16. The larger size of the Su-27/35, allows designers to do a lot more with it in terms of modifications and enhancements.

The Su-35 is to have some stealth capabilities (or at least be less detectable to most fighter aircraft radars). Russia is promising a fighter with a life of 6,000 flight hours, and engines good for 4,000 hours. Russia promises world-class avionics, plus a very pilot-friendly cockpit. The use of many thrusters and fly-by-wire will produce an aircraft even more maneuverable than earlier Su-30s (which have been extremely agile).

The Su-35 is not meant to be a direct rival for the F-22, because the Russian aircraft is not nearly as stealthy. The Su-35 will carry a 30mm autocannon (with 150 rounds) and up to eight tons of munitions, hanging from 12 hard points. This reduces stealthiness, which the F-22 and F-35 get around by using an internal bay for bombs and missiles. But if the maneuverability and advanced electronics of the proposed Su-35 live up to the promises, the aircraft would be more than a match for every fighter out there except the F-22. If such an Su-35 was sold for well under $100 million each, there would be a lot of buyers. Russia says it will begin production, and sales, in three years.

Su-35 bridges gap between current and next-gen fighters

By: John North
June 16, 2009


Sukhoi believes it is within two years of making first deliveries of its new Su-35 fighter as it prepares to add a third prototype to the flight-test program before the end of this month. The famous Russian design bureau is pinning its hopes on what it bills as a bridge between fourth-generation combat aircraft technology and the long-anticipated fifth-generation fighter that it expects will enter service in the second half of the next decade.


The flight test program started in February 2008 and passed the 100-flight mark on March 19 this year. The three test aircraft are due to make up to 160 flights among them. This year, Sukhoi expects to conclude static and super-agility tests en route to first deliveries in 2011.


Working largely at the KnAAPO factory in Komsomolsk-on-Amur, Sukhoi has already completed static tests to prove the Su-35’s flight capabilities in critical modes and the stability performance of the aircraft. It has also tested the fighter’s integrated control systems, navigation equipment and other aircraft systems.


According to Sukhoi, the Su-35 is a “4++ generation” fighter that represents the early integration of some aspects of fifth-generation technology. The aircraft, which made its public debut almost two years ago at Moscow’s August 2007 MAKS airshow, is billed as an interim step between existing Su-30 models and an as-yet not fully specified fifth-generation offering from the Russian defense industry.


So what is actually new about the Su-35? Well, first, the new fighter features an improved airframe that promises a dramatically increased service life of 6,000 flight hours or 30 years of operation. Time between overhaul is to increase to 1,500 hours or 10 years in operation.


Aerodynamically, the Su-35 is similar to the existing Su-27 and unlike the more recent Su-30MKI, it does not have a canard. All three channels have an electrical fly-by-wire system without mechanical cabling.


The fully fly-by-wire fighter uses a new integrated control system, developed by Moscow-based MNPK Avionika, which simultaneously handles several systems, including remote control, automatic control and the braking system to enhance the
aircraft’s handling capability and maneuverability. Also absent from the Su-35 design is the overhead brake flap, which is a standard feature of the Su-27, with its functions performed instead by an active rudder.


The Su-35 chassis has been reinforced to support the aircraft’s increased takeoff and landing weights. For the same reason, the front bearing has two wheels.


Sukhoi’s new fighter is powered by a new 117S version of NPO Saturn’s earlier AL-31F powerplant to provide additional thrust. The engine features a new fan, high- and low-pressure systems and improved digital controls.


The upgrade has boosted the AL-31F’s maximum thrust rating by 16 percent to just under 32,000 pounds. In maximum, afterburner-free mode, it generates just over 19,000 pounds of thrust. The new engine, which is to be built by Ufa-based Motor Building Association (UMPO), also promises significantly improved reliability with mean time between overhaul tripled from 500 to 1,500 hours


New Onboard Systems
The Su-35’s cockpit features a new information management system, which integrates functional, logical, informational and software subsystems into a single core to facilitate the interaction between crew and equipment. The new unit includes two central digital computers and all-glass displays.


The core of Su-35 cockpit suite is a pair of two 9- by 12-inch, multifunction liquid-crystal displays; a multifunction panel with a built-in display processor; a wide-angle collimated display on the windshield and a control and indication panel.
The displays can show video images and on these it can overlay synthesized alphanumeric and other symbology. The cockpit computer also can produce and send digital video signals to a video recording unit.


The onboard systems and armaments for the Su-35 are controlled by buttons and switches on the joystick, from where the pilot can also activate engine controls. There are duplicate control buttons on the multi-function displays.


Eyes and Ears
The Su-35 also promises to be markedly stealthier than its Sukhoi predecessors. The fighter’s radar signature has been reduced both in the X-radio waveband and also in the angle range of plus or minus 60 degrees.


The core of the Su-35’s armaments package is a new radar control system with an Irbis-E phased-array antenna (Irbis-E). It was developed by V.V.Tikhomirov Instrument Research Institute and promises improved target detection capability.


The X-waveband multi-functional passive phased-array antenna (PPAA) radar is mounted on a two-step hydraulic drive unit (azimuth and roll). The antenna device scans via an electronically controlled beam in azimuth and angle of elevation in sectors not smaller than 60 degrees. The two-step electrohydraulic drive unit additionally turns the antenna by mechanical means to 60 degrees in azimuth and 120 degrees in roll.


The control system detects and tracks up to 30 air targets at a time, retaining continuity of space scanning and engaging up to eight targets simultaneously. The Irbis-E unit detects, selects and tracks up to four ground targets in several mapping modes with various resolutions at a range of almost 220 nm, without stopping to monitor the airspace. Over the same range, the radar can detect air targets with a radar cross section of just over 32 sq ft.


Other new onboard systems of Su-35 include modern navigation and radio communication packages and a new electronic countermeasures suite. Finally, the Su-35 is equipped with new types of air-to-air and air-to-surface missiles, including long-range weapons.
