Merger Plans Shape Up for Russian Avionics Manufacturers

Russia & CIS Observer

â„– 4 (15) November 2006

Technocomplex, in turn, is a loose alliance of 18 avionics manufacturers based around the Ramenskoye Design Bureau. According to industry experts, Technocomplex revenues in 2005 did not exceed $360 million; net profit amounted to approximately $35 million. Technocomplex's income primarily comes from avionics deliveries for licensed production of Su-30MKI fighters in India. In addition, the company won a tender for the development and production of avionics for the Russian fifth-generation fighter, PAK FA.

Among the new developments presented by Technocomplex are the LINS-2000 laser inertial navigation system (developed jointly with France's SAGEM), and an avionics suite for the future Russian MS-21 passenger aircraft. Technocomplex also has presented a series of displays and control equipment: the MFPI-6 display panels, IKSh-1M wide-screen head-up display and MFI-10-6M multifunctional flat-panel color LCDs. These systems are to form the management and control systems for new and modernized aircraft and helicopters, including Russia's fifth-generation combat aircraft. Currently, Technocomplex produces all cockpit components for the new Russian Sukhoi Su-35 4++ generation fighter. The same components are considered as a transition phase towards the creation of avionics for the fifth-generation fighter.

It has been stated before by Givi Dzhandzhgava, President of Tekhnokompleks and general director of the Ramenskoye Instrument Building Design Bureau, that the cockpit configuration of the PAK FA ( atleast the initial version ) will be similar to the Su-35 cockpit. This is what Su-35 brings to the table in terms of cockpit.

The Su-35 has a "glass" cockpit. The main source of visual information for the pilot are two MFI-35 monitors measuring 9 x 12 inches. The can have two and four frames The tactical frame is depicted on the left display, on the right is the flying, which is joined with the airplane's operating system ((SISTEMA FUNKTSIONIROVANIYA)) and the defense frame. An electronic computer which operates in parallel with the airman provides automatic interchange of these "pictures." While the placement of the indicators and frames is not final â€“ according to the results of tests and "flights" in a simulator, the airmen are expressing their desired about how the would like to see the apparatus for transmitting visual information.

Vympel plans to develop air-to-air missiles for Russia's PAK FA fighter

19-May-2006 Janeâ€™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.

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 +/-60â…¹ off boresight, and the K-74M (izdeliye 750) with an angle of +/-75â…¹.

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 160â…¹ 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.

Quoting Pit from the Su-30 thread.

Now, there are US$ 2.300 millions planned for tactical weaponry for aircraft under the shield of the GPV-2015 program. Off course in that money there is a lot of other systems...

Some interesting tips:

K-30 R&D was stopped in 1997.

Ramjet R-77 R&D was stopped in 1999.

R&D for what it's now Izd 172S-1 (K-100-1) started on 1984.

Accord to some reports, Izd 760 would be designated "K-74M2".

Izd-170-1 was mentioned in one brochure for the Su-27SM, at Lipetsk Air Show, 2006.

Export version of R-77 is called Izd-190.

IR and PRH R-77 version were tested but not accepted to service.
Most of the current AAM and ASM developments at Russia obey the pattern of not using ANY ukrainian components on it. That's one of the reasons behind why never K-74 and K-74M appeared as final systems (and now Geofizika is handling the IR seaker and getting experience into it) or the Izd 180 leaves the lattice fins (actuators are Ukranian by Luch). Same history for Kh-59M and other ones.

There is a KAB-250S-E version in development (250 Kg GLONASS/GPS guided bomb)

Fighter frustrations

On the combat aircraft front, Mikhail Pogosyan, director general of Sukhoi Holding, complained in one of his statements for the press during MAKS'2005 about poor financial support for Russia's fifth- generation fighter programme. [/b]

The programme is codenamed 1-21 (Istrebitel, fighter for 21st century) in Russia. It has also been referred to as PAK FA or Perspektivnyi Aviatsionnyi Kompleks Frontovoi Aviatsii (Future Aviation Complex of Tactical Air Force). In April 2002, Sukhoi's T- 50 proposal won the tender for 1-21. In December 2004, the pilot project of T-50 fighter was approved by the state committee. According to unofficial information, in 2005 Sukhoi design bureau received less than $10 million for the T-50 project. Within the next, few years, programme financing has to ramp up, particularly after the start of prototype construction, tests and preparation for production.

At the show, information was released on 1-21's radar: Tikhomirov NIIP institute presented a small Epaulet-A active electronically scanned antenna (AESA) radar. Unlike another AESA radar, Zhuk-A, shown by Phazotron-NIIR company in the neighboring pavilion, the Epaulet-? was not a mock-up, but a fully functioning experimental radar dismounted for the time of exposition from the test stand. According to NIIP representatives, the radar operates within frequency range X (centimeter wavelength). The radiation power in each of the antenna channels "amounts to 8-1OW, which may be compared to 5-8W emitted by foreign radars"; noise factor amounts to 3dB, whereas the efficiency factor is about 30%.

The Epaulet-A radar has been built almost exclusively from Russian components with use of Russian technology, which is one of the basic conditions required by Russian air forces for the equipment to be installed in the fifth-generation fighter. The Epaulet-A is an experimental radar used for developing AESA technology and it is composed of only 68 transmit-receive modules; the next radars may be equipped with aerials of any form and size. The price of a single module "will be reduced to an acceptable level, provided that the same technology is used also for other series radiolocation systems made for military and civil applications" say NIIP officials.

OAK unveils plans for aircraft production reorganisation in Russia
By Vladimir Karnozov

Plans for a major reorganisation of Russia's production plants have been revealed by United Aircraft (OAK) in an effort to focus the country's aircraft output and improve efficiency.

Russia's aerospace industry is being integrated under the OAK umbrella. This reorganisation is designed to allow the production of combat aircraft to be increased fourfold and civil aircraft by 37 times over the next 15 years, to meet the output target set for OAK by Russian president Vladimir Putin.

The country's largest plant with 16,000 workers is Sukhoi's KnAAPO facility in Komsomolsk-on-Amur, which is completing Su-30MK2 assembly in preparation to switch to the Su-35 single-seat fighter from around 2012 and the PAK FA fifth-generation fighter. KnAAPO also assembles the Sukhoi Superjet 100, production of which is due to peak at 70 a year in 2011-12.

Production of Beriev Be-103 seven-seat single piston amphibian will be moved to Taganrog, while the 32-seat Su-80 turboprop is to be either cancelled or transferred to China.

The Irkutsk Aviation Plant is the second largest producer, employing 12,000 personnel. It is focusing on the Yak-130 new generation advanced jet trainer and its derivatives, including a single-seat strike aircraft and a an unmanned combat air vehicle.

Irkutsk's main product is the Su-30MKI fighter, which will be produced until 2014 to meet a long-term Indian contract, after which the plant will switch to the MS-21 airliner. The factory's Be-200 line will be transferred to Taganrog, following completion of the last two of seven aircraft ordered by launch customer, Russia's ministry for emergencies.

VASO in Voronezh, with an 11,000-strong workforce, will continue low-rate Ilyushin Il-96 assembly (three units annually) until 2012, when the line will close to make room for the Il-214 and MTA airlifter. In the interim, the plant will build the Antonov An-148 regional jet, initially in passenger form, and then as a freighter at an annual rate of 24 units from 2010. From 2015, VASO will build the all-composite wings for the MS-21.

VASO is also retrofitting Ilyushin Il-76s with Aviadvigatel PS-90A76 engines, primarily for the Russian air force, and when that programme is completed it will switch to low-rate production of Ilyushin Il-112 tactical transports.

The KAPO plant in Kazan, which employs 6,000 people, will primarily focus on upgrading Russian air force Tupolev Tu-95MS, Tu-22M3 and Tu-160 strategic bombers, while continuing low-rate output of the Tu-214 airliner and Tu-160, which is to be superseded by a next-generation strategic bomber. Under its own initiative, which is yet to have the support of OAK, KAPO is planning to produce 100-150 Tupolev Tu-334 102-seat regional jets.

Aviastar in Ulyanovsk employs 8,000 workers and will increase annual output of the Tupolev Tu-204 to 24 in 2010 (including KAPO's production of its Tu-214 variant). Aviastar's old An-124 Ruslan production plants are expected to be employed to produce the new-technology Il-76, dubbed the Il-476.

Tooling will be transferred from the TAPO plant in Tashkent, which is to gradually wind up Il-76 output and focus on producing the 64-seat Ilyushin Il-114 turboprop. TAPO will also build wings for the Antonov An-70 and An-124 empennage. Manufacture of wings for the Il-214 and MTA is also likely.

RSK MiG fighter production will be narrowed solely to NAZ Sokol in Nizhny Novgorod, where the MiG-31 interceptor and MiG-29UB two-seat trainer are built and refurbished. Upon completion of 14 Yakovlev Yak-130s for the Russian air force, production will be moved completely to Irkutsk.

Sokol will build the single-seat MiG-35 and MiG's new UCAVs, while the Moscow-based Znamya Truda plant will close. Some equipment will be transferred to LAPIK in Lukhovitsy, which will continue as a base for MiG upgrades and flight testing. LAPIK's newest shop, which was constructed for the Tu-334, will be used to carry out Airbus A320 freighter conversions from 2011-12.

The city of Taganrog on the Black Sea coast will house OAK's amphibian and flying boat centre of competence. After merging the Beriev design house and adjacent TAVIA plant, the centre will produce the Be-200 and Be-103 using tools transferred from Irkutsk and KnAAPO.

Taganrog will also supply maritime reconnaissance and anti-submarine warfare aircraft to the Russian and other navies, including retrofitted Tupolev Tu-142s and newly built Antonov A-40/42 Albatros aircraft.

Meanwhile, the plant in Smolensk, which produces the Yakovlev Yak-18T and Technoavia SM-92 Finist utility pistons, has become a member of the Tactical Missile Corporation centring on missile technology.

Russia to test fifth-generation fighter in 2009

LANGKAWI, December 6 (RIA Novosti) - Flight tests of a fifth-generation Russian-Indian fighter will begin as early as 2009 and mass production of the aircraft may start by 2015, the Sukhoi aircraft maker said Wednesday.

A Russian-Indian advanced multirole fighter is being developed from a Russian prototype by Sukhoi, which is part of Russia's United Aircraft Corporation (UAC), and India's Hindustan Aeronautics Limited, under an intergovernmental agreement signed in October.

"At present we are building prototypes of the fifth-generation fighter and will soon start preparation for flight-testing, which is planned for 2009," Sukhoi CEO Mikhail Pogosyan announced at the Langkawi International Maritime and Aerospace (LIMA) 2007 exhibition in Malaysia.

Pogosyan said mass production of the future fighter could begin by 2015.

The new fighter aircraft, which will feature high maneuverability and stealth to ensure air superiority and precision in destroying ground and sea targets, will be built at the Komsomolsk-on-Amur aircraft-manufacturing plant in Russia's Far East.

Discussing the future implementation of the Russian-Indian project, Pogosyan said joint efforts should be focused on three areas: coordination of technical specifications, application of advanced technologies, and preparation of a legal framework for future cooperation.

"We have conducted preliminary discussions on these issues and now we have to work out a detailed program for the implementation of the [fifth-generation fighter] project," the official said.

India and Russia have a long history of military cooperation, going back almost half a century. The existing Russian-Indian military-technical cooperation program, which lasts until 2010, lists up to 200 projects worth about $18 billion in all, according to Russia's defense ministry.

Russia starts developing new Indo-Russian fighter prototype

Russia has started the development of prototype of the Indo-Russian futuristic fifth generation fighter aircraft (FGA), a top defence official said today.

"Technical documentation has been passed on to the manufacturer and it has begun the construction of the prototype," Russian Air Chief, Gen Alexander Zelin, said.

The new fighter aircraft, which will feature high maneuverability and stealth to ensure air superiority and precision in destroying ground and sea targets, will be built at the Komsomolsk-on-Amur aircraft-manufacturing plant in Russia's Far East.

The serial production of FGA jointly developed by India and Russia is expected to begin by 2015, according to 'Sukhoi' officials partnering Hindustan Aeronautics Ltd under the agreement signed in October during Defence Minister A K Antony's visit here.

"At present we are building prototypes of the fifth-generation fighter and will soon start preparation for flight-testing, which is planned for 2009 and mass production of the future fighter could begin by 2015," Sukhoi CEO Mikhail Pogosyan said.

FGA, a futuristic multi-role fighter, is being developed on the basis of super secret PAK-FA project prototype by 'Sukhoi', now part of Russia's United Aircraft Corporation (UAC).

The Fifth Deviation

Source: 17.12.07, Kommersant â€“ Business Guide, Correspondent: Konstantin Lantratov

The winner in the tender for manufacture of the engine for the PAK FA will have enough work to keep the company busy for the next 13 years.

While in the United States everyone could read about the specifications for the engines for the F-22 and F-35 in the press, the requirements for the Russian engine have been and remain a state secret. What is known, however, is that the fifth generation engine is to provide not only high payload capacity and aircraft maneuverability, but also supersonic cruise. - Specific weight is the relationship of engine weight to thrust. For the fourth generation AL-31F engine it was nearly 0.12. This number is to be 0.1 in the fifth generation engine, that is 10 kilograms of thrust for every kilogram of engine weight.

Work on fifth generation engines began as early as the beginning of 1981 in the USSR within the framework of the Fighter-90 topic. The A. Lyulâ€™ka OKB was the lead developer of an engine with 18 to 20 tonnes of thrust. The classified designator of the engine was â€œArticle 20,â€

Sukhoi begins building fifth-gen fighters

MOSCOW, Dec 26 (Reuters) - Russian military airplane producer Sukhoi has begun test production of its multipurpose fifth-generation fighter jets, the company said on Wednesday.

The aircraft, designated as part of Russia's prospective battlefield aviation complex, are being built by Sukhoi at the Gagarin assembly plant in Komsomolsk-on-Amur in the far east. Test flights could begin in 2009.

In October Russia and India signed a deal to jointly modify the fifth-generation fighters for Indian use.

The new generation fighter will begin full-scale production in 2015, the company said.

The Sukhoi aircraft manufacturing holding develops and produces both military and civilian airplanes. In September the company unveiled its Superjet 100, a 90-passenger airliner with a 4,550 km (2,800 mile) range. (Reporting by Aleksandr Gelogaev; Editing by Ruth Pitchford

Sukhoi Gets India's Support for T-50 Fighter

Aviation Week Blog

Posted by Bill Sweetman at 12/28/2007 12:28 PM

At the end of December, Sukhoi reported that it started the construction of the first PAK FA prototypes â€“ also known as the T-50 â€“ at its manufacturing facility in Komsomolsk-on-Amur, Maxim Pyyadushin writes from Moscow. The prototypes should be ready for flight tests in 2009 while production of PAK-FA is to start in 2015.

Cooperation between Russiaâ€™s Sukhoi company and Indiaâ€™s Hindustan Aeronautics Limited (HAL) on the co-development of the PAK-FA took another step forward in mid-December, when the first negotiations on Indiaâ€™s technical requirements for the future aircraft were held in New Delhi, The next round is planned for January 2008.

According to industry sources, the joint fighter will in fact be the Sukhoi PAK-FA (T-50) but with about 20% of equipment, mainly avionics, replaced by Indian-made systems. Sukhoi CEO Mikhail Pogosyan has committed to support the development of additional modifications for India, including a ship-based derivative. This would be the first time for a foreign country to participate in development of a brand-new Russian fighter, although Indiaâ€™s support has been important in the evolution of the Su-30 and MiG-29 families.

The company-to-company discussions follow an October 2007 intergovernmental agreement between Russia and India signed an on the cooperative development of a fifth-generation multi-role fighter. â€œThis will be 50/50 cooperation in terms of intellectual property, resources and money,â€

Missiles for Russiaâ€™s Future Fighter

Source : Russia & CIS Observer
Date : 17 June 2007
Author : Piotr Butowski

Russia's new-generation PAK FA fighter â€” being developed by the Sukhoi Design Bureau â€” 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 â€” 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.

Thanks Jai. I assume (and desperately hope) that the $ 5 billion that India is investing towards the Pakfa gives it some access to the tech involved in making these missiles. Would love to see that izd 180 AND the KS-172 in IAF inventory. In service by 2010

lets see if they can keep their word. No baited breath here!
As far as the short IIR equipped missiles go, India seems to be working more with israel for the python V.

Regards,
CM.

Crude translation of news from Sukhoi's website.

{ A better translation would be appreciated }

Company "Sukhoi" - one of the leaders in the implementation of the state program of the armament

29.01.2008

The holding KnAAPO began the production of the first prototypes of the promising destroyer of the fifth generation (PAK FA) at the end of the past year. The flight tests of this machine can begin in 2009, and series production - in 2015.

The design of the Russian destroyer of the fifth generation, writes the "Red Star", interested India. In accordance with the intergovernmental agreement about the joint development and the production PAK FA are carroed out the sessions of Russian-Indian working group.

On them are discussed the questions, connected with the realization of project, by the distribution of the responsibilities between the sides, the periods of the fulfillment of works and their financing on the realization of joint project, and also the technical requirements, which Indian Airforce present.

The direct executors of project are determined to be the companies "Sukhoi" and largest Indian aviation corporation Hindustan Aeronautics Limited (HAL).

Fifth generation fighter to fly in 2009 - UAC CEO

MOSCOW
Jan 25, 2008
Interfax-AVN

The fifth generation tactical fighter program is underway in compliance with the set timetable, Alexei Fyodorov, the CEO of the United Aircraft Corporation, told Interfax-AVN, noting that the aircraft would be rolled out for the maiden flight as early as 2009.

The project is included into the State Arms Program through 2015, with the Defense Ministry of Russia named as the first client, he added.

The first aircraft will undergo a sequence of fine-tuning, while the second will be subjected to rigidity tests and the third one to flight tests.

There are some problems with project implementation, Fyodorov said, because it is actually the first time in Russia that the aircraft is being developed with the use of digital technologies, which require better production capacities and skilled personnel.

Furthermore, some new types of construction materials are going to be used, he added.

"As a result, we are going to get a real breakthrough in terms of flight and combat characteristics," he said, noting that the aircraft would carry most advanced airborne systems including navigation and weapon control ones

Extended Tests of Article 117S End Successfully at NPO Saturn in Support of Su-35 Airplaneâ€™s First Flight

Source: NPO Saturn 07.02.2008

Date : 07.02.08

There were 200 hours of bench tests in order to guarantee a service life of 100 hours. There were 6,000 cycles of turning the rotating nozzle, including 16 hours of hot tests with simulated high-speed modes.

The 117S engine is a major upgrade of the AL-31F and has a thrust of 14.5 tonnes, which exceeds the figures of the basic engine by 2 tonnes.

There are five engines in the batch: 117S-01 is for special tests in assuring first flight; 117S-02 is for gas dynamic stability and extended tests for assuring first flight; 117S-03 went to the flight laboratory where strain gauge measurements of the low pressure chamber under takeoff conditions were taken; 117S-04 and 117S-05 have been delivered for the Su-35 flight. Three more are to be built for a second Su-35. Tests of the first engineâ€™s final layout are to begin this month and delivery of the engines for the second airplane are planned for March â€“ April.

Note : 117S is also the preliminary / initial / interim engine for the PAK-FA.

IAF-HAL team to visit Russia

While the Russian version will have a Russian engine, the Indian version could have a western engine. The aircraft is likely to be operational around 2015.

Can some one explain this. Thank you

Its only a legal document, that we need so that later, the russians won't chew us even on things that we can't put anything else inside it other than russian origin ones.

Ensure, legally everything is possible our way and not their way., though we might use russian ones onlee for the start.

JaiS · Post by **JaiS** » 19 Feb 2008 02:17

Kuldip, it is not a JOCK ( sic ). It means that if the need be, India is given the option to integrate a western engine, if India can negotiate for one. The Russian one will be used otherwise.

Anyways, for archival purpose, posting some excerpts from the above article.

Led by the Air Forceâ€™s Assistant Chief of the Air Staff (Plans) Air Vice Marshal N.V. Tyagi, the team, which also has among its members an official from HALâ€™s Aircraft Research and Development Centre, Bangalore and another from HALâ€™s Aircraft Upgrades Research and Development Centre, Nashik, will leave for Moscow on Monday.

The funding, engineering and intellectual property is to be shared by the two sides in an equal measure. The fighter will be inducted into the air forces of both countries, besides being exported to third countries.

Official sources told The Hindu that issues pertaining to the preparation of a preliminary project report on the project, details of the work that has already been carried out by the Russian side, the eventual work share between the two sides, the work that Indian companies, especially HAL, should undertake, and costs will be discussed during the meetings.

While the Russian version will have a Russian engine, the Indian version could have a western engine. The aircraft is likely to be operational around 2015.

One presumes that the Russian engine will have 3-D vectored thrust.What western engines are available or planned that are similar?It will be quite unlikely that an American engine will be allowed.

karan_mc · Post by **karan_mc** » 19 Feb 2008 14:12

Western engine ?? are they talking about hybrid Kaveri with france ??

Sumeet · Post by **Sumeet** » 19 Feb 2008 14:43

Jai is discussion allowed in this thread ? If not I will edit this post.

But till then, Well possibilities can only be limited by ones imagination. One can say a western radar or engine or any subsystem can be added to Indian PAK-FA. Here article talks about adding a different engine which means:

1) First one has to develop 3D TVC. No one apart from Russia has that tech barring US.

2) One has to re validate the digital fly by wire for the new system [this engine + PAK FA body]

3) Honestly does anyone knows an engine available in the market that can replace what is suppose to go into PAK-FA final version ? Does anyone even know the specs of the final engine ?

4) New engine means new IR & RF signature management analysis.

Now what it could mean is that India might opt for JV with some western company to make an engine that will be the permanent feature on Indian PAK-FA of course the initial batch(es) being powered by Russian engine. Just like the situation of LCA. First GE then Kaveri.

Advantages:

1) India advances its technology base to develop latest generation engines with minimum IR and RF signature.

2) We gain in house expertise in making a TVC system 2D or 3D.

3) With LCA we have gained the knowledge of making quad FBW and with this program we gain knowledge of designing FBW for a TVC engine, integrating the engine and flight control system together. Very useful for our UCAV projects. Recall even the puki air chief once remarked TVC can help evade SAMs. UCAV being a deep strike platform might need that capability. Maybe some version of that engine can power our future UCAV.

Guys, with a 2015 timeframe for completion, all this is not possible. We will be going with a maximal russian fit, with MKIzing only if necessary. DRDO themselves are likely to be contractors for some systems- lets see which ones, and Natrajan/ADA are on record stating that their key interest is the MCA not a HCA..

Sumeet · Post by **Sumeet** » 19 Feb 2008 14:57

JC it might be possible for later batches. just like LCA. And there is no guarantee that 2015 deadline will be met. Few years ago it used to be 2012. Remember. Unless IAF doesn't shows explicit interest and is ready to cooperate how much should one read into statements about MCA ?

JCage · Post by **JCage** » 19 Feb 2008 15:13

Thing is that HAL is not exactly majorly into R&D at the system level. The programs they have launched are for an aggregate level, not subsystem & their recent focus on R&D will take a decade to show substantial results (same holds true for any org imho). Hence we wont be able to shoehorn different systems into a PAK-FA which by its very nature will have to be a very tightly integrated design, as you yourself have very precisely detailed. Avionics are a different issue though, and with todays Open standards, we might even see more LCA derivative tech get into the PAK-FA.

Coming to the MCA, ADA/DRDO themselves are quite confident that the LCA will get into service, and that a MCA will be sanctioned, if not a MCA then a LCA derivative with reduced RCS and more capability. Time will tell, I guess, but current focus is & should be on getting the LCA into service asap. IMHO, we will see more clarity about the MCA when the LCA gets into IOC/FOC ..

This integrating with western engine is a joke , you cant just integrate an engine with PAK-FA , because it has to meet many criteria of the AL-41F1 , else it will need some design changes and long flight testing.

Its better to go for deep TOT of AL-41F1 and its variants and manufacture them in india.

While the Russian version will have a Russian engine, the Indian version could have a western engine. The aircraft is likely to be operational around 2015.

I think its a good sign. Last time when Indians complained abt the failure rates of Su-30 engine, russians asked extra money to rectify it. So that wont happen again, if the news is true.
