Fifth Generation Aircraft (FGA). Type: 5th-generation multi-role, air superiority fighter. FGA is being developed by India and Russia under 50-50 Joint Venture program. It will be based on Russian PAK-FA project which is being developed by a consortium of companies spearheaded by Sukhoi OKB. It is scheduled to take off by 2008 and to be inducted by 2012. Indian version will be different that PAK-FA and will take off by 2012 and will be inducted in 2015. The total cost of development is estimated to be around $10-15 billion. The agreement was signed by the Secretary Defence Production Mr K P Singh and Deputy Director of the Federal Service for Foreign Military Cooperation Mr. Vyacheslav Dzirkaln in the presence of the Defence Minister Mr. AK Antony and his Russian counterpart Mr. Anatoly Serdyukov in Moscow on October 18, 2007.

here is the real pakfa engine with specificans.

engines, known as 117S, have been developed by NPO Saturn Research and Production Association.

In terms of engineering, the engines are substantially modified AL-31F production engines employing fifth-generation technologies. They use a new fan, new high and low pressure turbines, and a new digital control system. A provision is made for using a vectored thrust nozzle. The modernization has increased the engine special mode thrust by 16%, up to 14,500 kgf. In the maximum burner-free mode it reaches 8,800 kgf. Compared to today’s AL-31F engines, their capabilities will grow substantially, by 2 to 2.7 times. For instance, the between-repair period will grow from 500 to 1,000 hours (the operating period before the first overhaul is 1,500 hours). The designed period will vary between 1,500 and 4,000 hours.

The 117S engines will be co-produced by Ufa-based Motor Building Association and Rybinsk-based NPO Saturn Research and Production Association. The first production 117S engines were delivered to KnAAPO in early 2007 for testing on the first experimental Su-35 aircraft.

the new PAKFA radar

The Russian corporation Fazotron-NIIR has concluded development of the newest "Zhuk-AEh" active phased array aircraft radar for MiG-35 fighters. According to the firm's general director, Vyacheslav Tishchenko, it is the first active phased array antenna assembled in Russia. Its appearance brings out fighter closer to the main competitor, the American F-35 fifth generation fighter. Now our MiG is able to compete with the F-35 not only in combat but also in the worldwide arms marketplace.

It is thought that Russia was lagging behind the United States in the area of the development of future new, fifth generation aviation complexes. The Americans already have the F-22 Raptor ((in English)) heavy fighter which has gone into series production. The F-35 is still at the testing stage. But it already is clear that it will be one of the most prospective combat aircraft of the world. The United States and its allies already have ordered more than 3,000 such fighters. We still have more to think about than to respond to the Americans. As the say at the Sukhoy design bureau, at the firm that won the state tender for the development of the future fighter, "everything is going according to plan." The already are assembling the first examples of the new aircraft at Komsomol'sk-on-Amur, and the future S-117 engine for it is being broken in on the newest Su-35.

The appearance of the regenerated MiG is an event of the very same magnitude. The renovated electronic "stuffing" distinguishes it from the usual MiG-29. All airplane systems are controlled by on-board computers. Instead of analogue needled instruments there are liquid crystal panels. The newest Peterburg Klimov Design Bureau RD-33MK engines with fully rotating nozzles. In which connection, not only in "normal" flight regime, but also in afterburner. These properties radically distinguish the MiG-35 from the Su-30MKI itself or the American F-22 and F-35.

However, in modern combat all this is not enough if the aircraft and the pilots are "blind." The "Zhuk-AEh" solves this very problem. Such radars were installed only on the most modern American fighters until its appearance, and Western Europe still is unable to create them. The installation of the complex will bring our MiG-35 fully up to the Western competitors, and at the same time will increase the chances for victory in the tender offered by India for the MMRCA program for the delivery to Delhi of 126 fighters. Let's try to analyze the details.

Parabolic or slot antennas were installed on our previous airplanes. They had one signal transmitter and receiver each. An active phased antenna array is built on the principle of a comb, which consists of 680 miniature receiving and transmitting systems. Such an antenna (again in contrast to the "predecessors") is monolithic, that is it does not turn from side to side in the search for targets. This economizes not only the systems' weight (it no longer needs electric motors), but also decreases the time for detection by the radar of targets by an order of magnitude, the scanning beam shifts from one antenna point to another in split seconds.

The new "Zhuk" has an angle of view of plus - minus 60 degrees. Viewing range is 140 kilometers. It can simultaneously track 30 and fire at 6 targets. Both in the air and on the ground. At the same time, the new antenna allows resolving a number of tasks. To transmit data about the tactical situation to other airplanes, perform electronic warfare and terrain mapping. Exactly the same as it is done on the American F-35.

According to the head of the Unified Aircraft Building Corporation, Aleksey Fedorov, all this allows talking about the MiG-35 as one of the most prospective Russian fighters which brings it close to the new generation of combat airplanes in its capabilities. In case of winning the tender, as Russian experts note, India will receive not only the fighter itself, but also the technology for producing the new radars with the active phased antenna array.

technical details about its performance.

This 3cm (X-band) radar. The Russians designed their radar to produce linear power output at the range of 6-8 watt, to address available power (provided by the aircraft) and performance (range). The radar uses multiple four channel transceivers modules generating an output of 5watt per channel, installed on a liquid cooled base plate to dissipate the generated heat. If a specific transceiver is overheated, it will be switched off by the radar computer until it cools down.

Zhuk-AE can detect aerial targets at ranges up to 130 km (head on) in both look-up or look down modes. Look-up tail-on detection range is 50km (40km look down). The radar can track 30 aerial targets in the track-while-scan mode, and engage six targets simultaneously in the attack mode.

The radar provides target designation data for various Russian made missiles such as the R-27R1(R1E0, RVV-AE, R-73E, Kh-31A, Kh-35E and R-27T(TE) missiles. The radar can distinguish and count closely flying targets as well as identifying targets with known signatures. Close maneuvering combat mode optimizes the system's performance to provide effective vertical scans, coverage of the HUD field-of view, and slew to follow the helmet sighting angles. Special optimization is also provided in the helicopter detection mode, detecting and attacking slow-flying and hovering targets. In the air/surface mode the radar supports ranging, mapping and tracking of moving targets, The radar supports real-beam, Doppler beam sharpening and focused synthetic aperture modes, offering different map scale expansion, map 'freezing', and tracking of four targets, including ground or sea-surface moving targets. It has a sea-surface search mode. The Zhuk AE can detect a destroyer size target at a range of 200 km.

the new missiles for pakfa

Russia's new-generation PAK FA fighter — being developed by the Sukhoi Design Bureau — will have not only feature a new airframe, radar, avionics and engines. It also will be equipped with new-generation weapons that are being evolved in two parallel paths: the continued modernization of existing missiles with stepped improvement of their capabilities; and the design of next-generation weapons.
GosMKB Vympel, Russia's leading air-to-air missile design bureau, is busy evolving a full spectrum of missiles for the PAK FA, ranging from short-range weapons to long-range variants. In 2010, Vympel expects to complete its development of the short-range Izdeliye 760 missile — which is a significantly modernized version of the R-73 weapon, outfitted with an inertial flight control system and course correction receiver, improved rocket engine and with new multi-mode infrared seeker. The Izdeliye 760 is expected to be a close counterpart to the Western-built ASRAAM and Sidewinder AIM-9X missiles.
Three years later, the new-generation K-MD short range missile (also to be designated the Izdeliye 300) is to be operational. When compared to Izdeliye 760, the new missile will have longer range and will be capable of being launched from any direction; it will be also more resistant to jamming. The K-MD will be fitted with a new imaging infrared seeker enabling identification of target according to memorized images. The seeker's lock-on range will be two times greater than the seeker for the Izdeliye 760 missile. A new adaptive warhead will be introduced, and the missile's control will be performed with aerodynamic surfaces, as well as a thrust-vector engine nozzle.
Russia's most modern medium-range air-to-air missile is the R-77 (Izdeliye 170) and its export derivative RVV-AE (Izdeliye 190). A phased modernization of this weapon, designated the K-77-1 (Izdeliye 170-1), is now being tested. In addition, the K-77M (Izdeliye 180) missile is currently under development as a second step in the R-77's modernization. The most visible change in the Izdeliye 180's external appearance compared to the R-77/RVV-AE is replacement of its latticework fins by more common flat aerodynamic control planes. This reduces aerodynamic drag and cuts down on the radar cross-section. The missile will be fitted with a modernized active radar seeker and new double pulse solid-propellant engine. Its maximum range will be 2-3.5 times more than the Izdeliye 170 (R-77) missile, depending on the launch altitude. The Izdeliye 180 is expected to be better than the AMRAAM AIM-120C7 missile, and equal to its successor versions, with a service-ready date targeted for 2010.
A future medium-range air-to-air missile as a follow-on to the Izdeliye 180 also is in development, but no additional information has yet to be released about this weapon.
Russia is the only country developing ultra-long range air-to-air missiles able of reach targets at distances of up to 400 km. Two such missiles are competing to be a basic weapon on the PAK FA fighter: the Izdeliye 172 (K-100) from Novator, and the Izdeliye 810 from Vympel.
All air-to-air weapons on the PAK FA (including the largest Izdeliye 172 missile) are designed to be carried in the aircraft's internal weapons bay. To allow these weapons to be deployed from the internal bay, Vympel is designing two types of ejection release units capable of carrying 300 kg and 700 kg loads
The PAK FA also is expected to carry its basic complement of air-to-ground weapons internally. These include the modernized Kh-58Ush long-range anti-radiation missile, the newly-developed Kh-36 short-range anti-radiation missile, the new short-range electro-optical Kh-38 missile, as well as the UAB-250 and KAB-500M guided bombs. Heavier weapon types will be carried on the aircraft's external pylons.

Difference between PAK FA and FGFA

The difference between PAK FA and the FGFA will be similar to that between Su-30MK and Su-30MKI. Su-30MK is the commercial version of the Russian Su-30M, where as the Su-30MKI (MKI stands for "Modernizirovannyi Kommercheskiy Indiski" meaning "Modernized Commercial India".) jointly-developed with India's Hindustan Aeronautics Limited for the Indian Air Force. Includes Thrust Vectoring Control (TVC) and canards. Equipped with a multi-national avionics complex sourced from India, Israel, Russia and France[9]. The PAK FA and the FGFA will be having minimum of common technology. Further the FGFA will be predominatly using weapons of Indian origin such as Astra a Beyond Visual Range missile being developed by India. The Indian FGFA is significantly different from the Russian PAK FA because a second pilot means the addition of another dimension, development of wings and control surfaces.

PAKFA is suppose to be on the level or above a Raptor

sir the pakfa is still not out so exact parameters are hard to figure out,but its an intermediate class between the raptor and the jsf.
the raptor is a reality and pakfa is still at the boards so there is no comparing the two still the pakfa is really flying.

thanks.

Invincible I noticed the radar says X-band if true this might be the first Fighter plane using X-band radar and it could even be utilized as an AWAC if necessary?

sir you are right about the fact its claimed to be a counter stealth radar by the russians, as it can detech stealth fighters at a distance the size of a golf ball.

thnx

 

[LETHALFORCE]

I am more excited about PAKFA and LCA than our MRCA pick.

LF buddy isn't LCA MMR works in X band?

Correct me if I am wrong though.

Indo-Russian FGFA project set to take off

BANGALORE: Keen on replicating the success of the Indo-Russian supersonic BraHmos cruise missile project, the defence establishments of both the countries are willing to bury their differences over the fifth generation fighter aircraft (FGFA) and get the project kickstarted by the middle of this year.

The FGFA study programme which was initiated between India and Russia in 2007, has been a slow-starter as the Air Forces of the two countries have had differences over the aircraft project.

While the Indian Air Force wants a two-seat version to meet the requirements of India’s air superiority policy, the Russian Air Force wants a single- seat version.

“There have been differences between the two Air Forces as both have specific requirements.

These issues will be sorted out soon and by the middle of the year we expect to start work so that the aircraft is inducted by 2017,” M Fakruddin, Director-Corporate Planning and Marketing, Hindustan Aeronautics Limited (HAL) told to The New Indian Express.

A general contract had been signed in December last year between HAL and Rosoboron Export for the design and development of the aircraft by the Sukhoi design bureau and the Indian aviation major.

The fifth generation fighter is expected to feature high manoeuvrability and stealth in order to ensure air superiority and precision in destroying ground and sea targets.

Lockheed Martin’s F-22 Raptor and the F-35 Lightning II are among a few of the fifth generation fighter aircraft in the world.

MRO facility on hold

HAL’s plans to set up an aerospace MRO (maintenance, repair and overhauling) facility at the HAL airport has been put on hold due to the economic recession.

“The MRO facility at the HAL airport is on the backburner, as we do not see it feasible at this point of time to have one. The rise in fuel prices, the decrease in passenger traffic and the economic slowdown have all impacted the business. We have decided to wait for some time,” said Fakruddin.

HAL had been mulling over the idea of starting a MRO facility at the HAL airport after the commercial flight operations shifted to Bengaluru International Airport last year.
