MOSCOW, April 13. (ARMS-TASS). Creating so-called engine of Phase 2 for the future aviation system tactical aircraft (PAK FA) is ahead of schedule. About it, ITAR-TASS news agency, told reporters today the managing director of Scientific-Production Association (NPO), "Saturn" Ilya Fedorov.
Completion of development work and delivery engine of the Defense Ministry through the company "Dry" is planned for 2015
"We have units of Saturn and interacting structures working on the draft design engine. All agreed. Works are in Moscow, Rybinsk and other venues. We have a strong belief that the engine of the second phase will be done sooner than anyone expected," - Fedorov said.
According to him, too long development time and continue to produce the engine a second phase, which is already used to test samples PAK FA, is economically inefficient. "
"Work on the promising engine model at a very advanced stage, although we do about it prior to the meeting under the leadership of Deputy Prime Minister Sergei Ivanov did not say. When all the organizational problems were solved, we have shown our saturnovskie of use" - "Fedorov said.
The use of composite materials and innovative technology, aerodynamic design aircraft, measures to reduce the visibility of the engine provides unprecedented low level of radar, optical and infrared visibility of the PAK FA. This allows us to significantly improve the combat effectiveness of the work both by air and ground targets, at any time of day, and adverse weather conditions, according to military experts.

"Item 129" for the PAK FA will create ahead of time


http://www.lenta.ru/news/2011/04/13/pakfa/

Creating a jet engine of the second phase ("Item 129") for a promising fighter T-50 (PAK FA) is ahead of schedule. On this, as reported by ITAR-TASS news agency , said the managing director of NPO Saturn Ilya Fedorov. According to him, the completion of development projects and delivery of the first engines of the Russian Defense Ministry is currently planned for 2015, when the first fighter T-50 should begin to come into service.
"We have units NPO Saturn and interacting structures are working on the draft design engine. All agreed. The work carried out in Moscow, Rybinsk and other venues. We have a strong belief that the engine of the second phase will be done sooner than anyone expected," - Fedorov said, noting that "stretch the development time and continue to produce the engine of the first stage (" Item 117 ", AL-41F1 - note "Heathcliff!" ) is economically inefficient. "

According to plans, development and production of fighter T-50, the engine of the first stage - the AL-41F1 - will be used in the prototype aircraft and the first production models, which will start arriving at the Air Forces of Russia in 2015. This engine is capable to develop traction in 86 Kilonewton in normal flight and in 147 Kilonewton in afterburner mode. In addition, the AL-41F1 is equipped with a plasma ignition system, vserakursny thrust vector control and digital engine control system.

It should be noted that the Su-35s will be installed less powerful version of the engine AL-41F1 - AL-41F1S (Item 117C). From his "older" version of it differs obsolete digital engine control system and reduced by nearly five Kilonewton traction.

The engine of the second phase - "Item 129" - will be installed at a later installment PAK FA. A new power plant is still unknown for many. Previously reported that the "Product 129" will be different from the AL-41F1 increased traction, as well as higher fuel efficiency. Supposedly, the engine of the second phase will develop a thrust of 107 Kilonewton in cruising flight and in 176 Kilonewton in afterburner mode. Also likely to be significantly increased TBO.

According to Sukhoi, which creates the PAK FA fighter tests go according to schedule. Currently, flight of the two prototype T-50. The first prototype of the T-50 is involved in flight tests in January 2010, the second such aircraft joined the program in early March 2011. According to schedule, test airframe PAK FA will be completed in 2011-2012. In 2013, the Russian Defense Ministry received ten experienced the initial batch of machines that will be tested in combat use.

Russian stealth experience with foreign avionics

http://www.newsru.com/russia/18jun2010/tu_50.html

experts generally give negative ratings outlook re army and navy. According to experts, over 20 years did not create any new tank or plane, and the Russian Army adopted only one helicopter. According to experts, the flight-test T-50 at the plant were using French technology. On the prototype T-50 was installed avionics import, domestic tested on another machine. Russian electronic filling to replace the French. On the observations of experts, it will not make the T-50 cheaper than Western counterparts.

Putin, on the eve of watching the flight of the T-50, noted that the fifth-generation fighter will be priced cheaper in 2,5-3 times as compared with foreign counterparts. As the prime minister said, it will be a machine that will outperform the U.S. F-22 in maneuverability, armament and range.

As Putin said at the first stage of creating an aircraft spent 30 billion rubles, to complete the project needed another 30 billion will then begin upgrading the engine and aircraft armament.

Marginal rate of PAK FA - 2600 km / h, maximum besforsazhnaya speed - 2100 km / h. Practical flight range of 4300 km. Armed with machine consists of a 30-mm gun, 8 internal points of suspension and 8 external. For comparison: the marginal rate of U.S. F-22 Raptor is 2,410 km / h, maximum speed of the aircraft besforsazhnaya - 1963 km / h. His practical flight range - 3,219 km. At the armed F-22 20-mm gun, 8 internal points of suspension and 4 outside.

Interfax-AVN, April 21. Obninsk Scientific-Production Enterprise (SME), "Technology will participate in the production of promising aviation complex tactical aircraft (PAK FA, code T-50), said on Thursday, Deputy General Director of the company on research and innovation work Oleg Commissioner.

"NPP has mastered the production design of 28 elements of the wing and fuselage fighter T-50 made of composite materials. The fundamental decision on the participation of enterprises in the mass production of the fighter made", - said A. Commissioner "Interfax-AVN at the 12 th International Forum" High Technologies 1921 Century "(BT-21) in Moscow.

"We are talking about development in the production of structural elements of the T-50 from high-quality carbon fiber. Under the issue of structural elements of aircraft composites organized their pilot production" - said the agency interlocutor.

He recalled that in the ongoing development work on the T-50 holding "Dry" last year were delivered several sets of design elements.

In addition, in the interests of making the fighter business can also supply on-board navigation lights - they are well kept the temperature does not change color, "- said Oleg Commissioner.

"With these supplies, we proved that we can make high-quality parts from new materials and new technologies. The production of these parts is very complicated and not every company is able to deploy a series of experimental and serial production", - said the representative of the SPE "technology."

April 21. Scientific-Production Enterprise "Tekhnologiya" (Obninsk, Kaluga region) offers the latest developments in nano-coating for the latest Russian fighters, said deputy general director of SPE technology Oleg Commissioner.

"Nanostructured optical multi coating reduces glare on the glazing, reduce heat radiation and visibility to enemy radar screens," - said A. Commissioner "Interfax-AVN at the 12 th International Forum" High Technologies of the 21 Century "in Moscow.

He noted that the PNP "Technology specializes in the design and manufacture of composite and ceramic materials, and glazing of high-speed vehicles, primarily aircraft for military and civil purposes. According to him, the company for the Su-35 fighters and T-50 (fighter 5 th generation) provides no glass, and inflicts upon them a special coating.

"Applied nanocoating are developing SPE" technology "which makes them" - added O. Commissioner.

He said that earlier SPE technology "has a small laboratory chambers, and three years ago, the company has implemented more large cells of more 2 metersfor the production of coatings.

A. The Commissioner stressed that "technology and coatings for use on glazed light fighter in Russia does not have any other company."

According to him, SPE technology has been successfully implementing the civil sector, its military development. In particular, NPP technology produces a head-selikatnoe glazing for civil and military aircraft. In addition, up to half of Russian trains have a head-glazing production of SPE technology. " The company also offers high strength, heated and not misted windscreens for subway trains.

Amazing picture , thanks to anshu with all the pakfa updates , a lot of things are going better than expect , especially the engine front looks to be working ahead of schedule , also the wings in development is going on well.

also the important part if any of you followed it or not the SU35 BM entered into final phase of induction and production which should be politically good for the speed aspect of pakfa as many believed pakfa was being delayed due to cover the BM market sales.

The SU35BM to enter the brazilian FX3 - new tender as a possible sales.

Technology "black wings" T-50 (PAK FA) - the use of advanced composite technology in the Russian aircraft

Сделано у нас - Технология "черного крыла" Т-50 (ПАК ФА) - использование новейших композитных технологий в российском авиапроме

Wing T-50 - a typical composite structures. Inside - aluminum honeycomb top and bottom - about a hundred layers of carbon fiber. After laying this "sandwich" will go for 8 hours in an autoclave, which will turn into a high-strength, and most importantly, light aircraft components. Thus was born the unique "black wings" PAK FA - promising aviation complex tactical aircraft - the T-50.

"Despite the seeming simplicity of the technology in order to begin the process of calculations, we need special equipment. This snap is made from composite materials, it is presented to a number of requirements. This is also a science-intensive products ", - says the academic secretary ORPE" Technology "Igor Shkarupa.

Wing T-50 - a typical composite structures. Inside - aluminum honeycomb top and bottom - about a hundred layers of carbon fiber. After laying this "sandwich" will go for 8 hours in an autoclave, which will turn into a high-strength, and most importantly light aircraft components.

"Virtually the entire fuselage of the fighter and the panel - this is done at our company. First, we had 18 products, then it became 22, and soon with the Voronezh aircraft manufacturing plant we passed, and the production of the tail part of the destroyer "- says CEO ORPE" Technology "Vladimir Vikulin.

For the fifth-generation fighter in Obninsk Scientific-Production Enterprise "Technology", part of the concern Himkompozit "corporation Russian Technologies, have developed a special carbon fiber material . The main technological know-how in the so-called prepregs - semi-finished materials. Their characteristics are directly dependent on how homogeneously alloyed carbon fiber and resin part.

"These technologies are in the world is very closed. For example, the technology of getting a good carbon fiber possess 2-3 countries in the world. And buy it impossible. Either you have to develop it himself, or will buy the finished product, there are airplanes, etc., but he already can not do it ", - says General Director of the Moscow Engineering Experimental Plant - Composite Technology Valery Litvinov.

In Obninsk work with composite materials began in the 70's of last century, the development of a unique space system, "Energy-Buran". Now the company has mastered mass production of large payload fairing for launch vehicles "Proton", "Rokot", "Angara of the composites.

"They are not inferior in strength metals for durability, they have advantages and they are several times lighter than metals, and here for space purposes is very important, because the run kilogram into space - it's very expensive", - says Vladimir Vikulin.

Civil Aviation composites can not do without. The new Russian trunk MS-21 aircraft to be more than 30 percent.

In the aircraft from the usual materials passengers at the height of sometimes uncomfortable due to lack of oxygen and pressure drops. The manufacturer promises that the gliders made of composites such negative feelings will not be.

"If the next generation of aircraft will be made from these materials, the person will be flying, being as though all the time in the state at ground level. This is a totally different quality of flight ", - says Valery Litvinov.

Last December, the Moscow region bound "freezing rain." Trees, roads, rooftops, cars covered with a thick layer of ice. Unable to withstand the stress the trees began to fall, breaking the wire transmission lines. More than two weeks without electricity were about 400 thousand inhabitants of Moscow suburbs. Catastrophic consequences can be avoided if the wires were above the forest, and electric poles - made of composites.

"We are developing such a project and do so that, for example, on one wagon or truck with a trailer could be this 50-meter to bring support and mount, and without any lifting of funds", - says Valery Litvinov.

It is for such important projects for about a year ago on the basis of the Moscow Machine-Building Pilot Plant - Composite Technology was established Engineering Research and Production Center. Enterprise Concern Himkompozit "ready to move from project to commercial production. Life shows the future - for those materials.

They consider it joint development. After all we will be providing the mission computers, composite design and navigation systems. We have 25% of the project to handle and that is quite a lot considering how far the Russians themselves have progressed.

Hey guys.....

I have one question from long time in my mind.......
can anybody tell me that what is RCS of pakfa and Su30mki ???

sorry for asking Su30mki in thins post...... but please if you can answer it will be really appreciated.

thanks......

Those are just token gestures, mission computer is not a big deal. Its just an memory card which shows which track to follow, navagation system is no big deal either these days considering an Nokia phone has GPS and composite design was already done by them so i dont understand what we have left to do with that.

You talk with any russian online they will deny that we have anything to do with it apart from give our share of dollar.

How are contractual obligations token ?

It took many months of Negotiations to get HAL 25% development share , from the Russian offer of 15%.

This is Joint development in the same way Brhamos is Joint development. The entire JV model is based on what we did with Brahmos.

mission computer is not a big deal. Its just an memory card which shows which track to follow, navagation system is no big deal either these days considering an Nokia phone has GPS

Avionics is not big deal ? , i seriously suggest you brush on all the functionalities of these systems , ou will find they are very broad and demanding.

Mission computer is more than just a line on map , and Navigation is far more than just simple GPS. These are very complicated systems software wise. They have to work extremely fast and they need to have lot of redundancy to with crash's.

composite design was already done by them so i dont understand what we have left to do with that.

IAF wants a lighter aircraft , by almost 10 tonnes , but it should be large enough to accommodate 2 pilots.
Part of the drastic weight shedding is in use of greater Composite materials.

Reduced weight and addition of an extra pilot are but some of the many changes between the PAK-FA and FGFA. Most of which has to be also reflected in the airframe.

Beyond all this the fact that HAL gets full ToT and equal control over the aircraft exports qualify this as a JV.

Don't know how many Russians you have been speaking to. Unless it is Mikhail Pogyosan I am not interested. 25% of workshare is MASSIVE.

Navigation systems are based on emitters. As long as your aircraft is emitting, stealth is compromised if detected. It is a big deal if you can communicate with your satellites without giving away any information to the enemy.

Let's just say your Nokia Phone with GPS is not even 0.1% of the complexity required for a stealth design.
