PICTURE: Russia unveils AESA radar for PAK FA fighter
Russia unveiled the first element of its fifth-generation Sukhoi PAK FA/T-50 fighter during the Moscow MAKS air show, with Tikhomirov's NIIP having exhibited the type's active electronically scanned array (AESA) radar. The newly unveiled unit is intended for integration with Sukhoi's heavyweight fighter prototype, which air force commander Aleksandr Zelin says is due to fly in November or December. The aircraft was shown to President Vladimir Putin in its assembly phase during his May visit to the KnAAPO production plant in Komsomolsk-on-Amur. Tikhomirov says the AESA antenna entered benchtesting in November 2008, and was mated with the radar's other blocks for an initial integration test "this summer". A second example to be produced for an operational prototype of the T-50 will be completed by mid-2010, it adds. NIIP has not provided any details about the new radar, beyond saying that its antenna contains more than 1,000 solid transmit/receive modules. The design is Russia's second AESA system, following the Phazotron Zhuk-AE being developed for the RSK MiG-35. Outwardly, the T-50 is believed to resemble the configuration of the US Air Force's Lockheed Martin F-22, and will share design features such as internally carried weapons and supercruise performance. The Russian aircraft will also have an integrated on-board sensor and flight control system which will include several radar antennas to provide a 360° coverage. Sukhoi will complete five prototypes for initial testing, including two to be dedicated for ground test activities. Initial trials are scheduled for completion in 2011-12, with the company expecting to produce an initial batch of aircraft for operational trials by 2015. Russia's initial batch of aircraft will be powered by NPO Saturn Item 117 engines, derived from the supplier's AL-31F series. A new engine will be incorporated with later production examples, with this likely to be a design proposed by MMPP Salut and based on the AL-31FM3. India is also seeking its own version of the T-50 under an agreement with Moscow. This is expected to feature some airframe differences and use Indian avionics equipment.

I thought NPO Saturn was going to be responsible for the 5th generation engine, with the Article 117S (are they going to hurry up and give it a real designation already?) being the interim for the first prototype(s?).
I didn't think Salyut was doing anything other than making their own 'interim' upgrade engines, like the AL-31FM1 for the Su-34. Speaking of which, is the AL-31FM1 equipping any other aircraft, like the Su-27SM? I heard it was supposed to.

NPO Saturn have developed the 117-S engine(14.500kgf) for the Su-35, witch in any case are a moderate/heavy upgrade from the AL-31F containing the same engine core. The AL-31FM1 engine(13.500kgf) will indeed be on the Su-27SM and Su-34. Those engines are MMPP Salut upgrade! The AL-31FM2 will be MMPP Salut answer to NPO Saturns 117-S engine and will produce around 14.000kgf-15.000kgf. The AL-31FM3(Salut) will in the future produce somewhere around 15.000kgf +. All these are interim engine based on the AL-31F core, but heavly upgraded. I think they will all be mountet on future Su-27SM and the Su-34 in the RuAF as more are procured over time. Here is some aditional info from MMPP Salut : "The adjustable nozzle with controlled vector thrust for the AL-31FM1 engine,made by ADPOPD of MMPP Salut, offers an example of NX’s comprehensive use. Early in the project a full 3D model of the hinged nozzle was created in NX. The model contained about 3,000 parts, 500 of which were original. Prior to production, NX made it possible to check potential interferences in the digital assembly, to see the presence and sizes of clearances, and to determine the weight and the center of gravity of the nozzle, even as design properties and characteristics changed. In addition, the full 3D model allowed design optimization in the context of the complete assembly. The availability of 3D models of cast parts considerably decreased the time needed to produce physical samples by allowing the use of rapid prototyping technology instead of waiting for injection-molded samples. Having 3D models of parts, especially those with complicated shapes, also accelerated the development of programs for the measuring machines, which improved the quality of the parts". http://origin-www.ugs.com/en_us/abou...omponent=59328 Edit: Hopfully the AL-31FM1 or FM2 will also find its way to the IAF MKIs Flanker for the next upgrade Phase III, but it still remains to see.. The Irkuts plant produced Su-30 series slated for Vietnam and other export countries will also feature FM1 and later on FM2 engine. The new AL-41F engine core(Pak-Fa) will feature somwhere around 15.500kgf-17.000kgf. Perhaps the first block will be around 15.500kgf+, but will have good growt fundation as further development goes by. The new AL-41F are still very much under development by NPO Saturn, suffering delays.. Thanks Last edited by haavarla; 7th September 2009 at 20:41. |

The Article 117S (aka AL-41F-1A @~33,000lbs thrust) is in essence a scaled down AL-41F, which outperformed Salyut's AL-31FM2 in bench tests. With the AL-31FM3, Salyut may be giving Saturn 'the finger', along with the RuMoD- who have paid Saturn the ca$h and want to know where their engine is, (afaik, there was a corruption scandal @ Saturn recently along with a Kremlin bail-out loan- hence inevitably ceding some control). Hence, with the 31FM3, Salyut may now be re-assigned as lead developer for the PAK-FA engine, Zelin alluded to such when he expressed disappointment at progress and stated the definitive article would be based on Salyut's AL-31FM3- this is a surprising & new development. Then you have to ask, why didn't they just design the PAK-FA around the original AL-41F?

 The Saturn 117S will be the powerplant for the Su-35S (production Su-35BM) Flanker-E and Su-50 PAK FA prototypes until the AL-41F turbofan (PW F119-type) comes into operational service. Both engines have supercruise capability. The Su-35 can supercruise at Mach ~1.05 with full load, while the PAK FA cahn supercruise at Mach ~1.6+ Quote:

Minituarizing a powerful turbofan is complex work, requiring the correct metallurgic formulae, careful atleration of the compressor blades, fuel injectors, gearboxes and FADEC systems. When the supercruising turbofans sufficiently mature, that's when NPO Saturn has developed the most powerful fighter turbofan, ahead of the PW F119 and F135.  NPO Saturn 117S

This is the only stuff so far on the Su-35: Russia & CIS Observer / Archive / №3 (22) August 2008 / DEFENSE / Sukhoi Su-35 Achieves Supercruise Flight / By Vladimir Karnozov "Surplus power: During the test flight at the highest thrust regime without the use of afterburner the Su-35 achieved Mach 1.1 speed and was still accelerating By late June, the no. 1 flying prototype had completed 13 test missions. These were devoted to assessment of the airplane's stability and controllability, maneuvering characteristics and powerplant performance. In addition, the operation of onboard systems was closely monitored. Having received a generally positive assessment of the aircraft, Sukhoi sent it into the supersonic regime. On mission 12, the airplane accelerated to Mach 1.2 at medium altitudes (up to 6,000 meters). The next flight went as high as 11,000 meters and reached speeds of Mach 1.3. Importantly, the airplane demonstrated its ability to maintain supersonic speed at military power (the highest thrust regime without the use of afterburner). Sergei Bogdan selected his words carefully, but did state: "At medium altitudes and with military power, the airplane was making a moderate supersonic speed and still accelerating. In one of the flights, I achieved Mach 1.1, and while the aircraft could accelerate further, I had to slow down because I was approaching the end of our supersonic flight zone." Sukhoi continues assessments of the recorded parameters in order to determine whether the airplane had actually attained supercruise. Additionally, the company continues to define altitudes, weights, external and internal loads at which the Su-35 can reach its supercruise performance. A number of additional missions shall be devoted to these assessments. "The power reserve is clearly seen when the Su-35 is accompanied by a Su-30," Bogdan says. "During the very first mission, I had the chance to assess how well the Su-35 responds to the throttle. When I was accelerating at combat power, the chase plane's pilot had to use afterburner from time to time. And still, he was going slower." In afterburner, the Su-35 accelerates much faster than the original Flanker. This is due to the increase in engine power at full afterburner from 12,500 to 14,500 kgf. During takeoff, the ground run is shorter, as the pilot is given much more freedom in pulling back on the stick. The onboard computer takes responsibility for preventing tail strike and other unwanted consequences of over-rotation. With smart computer control over critical regimes, the Su-35 can become airborne much faster than legacy fighters, taking full advantage of excessive power and superagility."

Ilya Fedorov: The engine of the fifth generation integrates the best of what is today in Russia's engine industry-
In created in Russia Joint new engine corporation special role of the Scientific-Production Association "Saturn".The company now sells a number of major engine program, on which depends the whole future of Russia's aviation. What kind of program to "Interfax-AVN said the new head of Saturn Ilya Fedorov. The Interfax-AVN, September 3, 2009 - Ilya, will the "Saturn" to develop the engine of the fifth generation? - No one questioned the participation of our company in this program, because all that we have today on the fifth generation fighter aircraft has been reached, as we know, the engine that made the Saturn. - Do you mean the engine 117S, which are equipped with a multifunctional fighters Su-35 and which, according to experts, is largely consistent with the requirements of the engine of the fifth generation? It was created as a result of deep modernization of the engine AL-31F.But if we're talking about an engine for future aviation system frontline aircraft (PAK FA), it must be a completely new engine that nobody, including Saturn, alone can not do. Similar developments were carried out with the broad cooperation. Incidentally, the domestic engine building since the Soviet Union has traditionally been the distribution of roles between the design bureau, which specialized in the development of various engine components. I am sure that this is what will be developed and the engine of the fifth generation. Who will act as an integrator in this project will determine the customer - Air Force Russia. But those developments that have at our company, allow a high probability to assume that "Saturn" will remain the lead organization for the development of fifth-generation engine, as defined previously. - What other component and engine company will be included in co-operatives to develop a power plant for the PAK FA? - I think, in dealing with such large-scale task will involve all the component and engine design bureau, non-integrated new engine corporation.It is known that the best laboratory facilities for fine-tuning of engine components than SNTK behalf Kuznetsova, found nowhere else in the world. Although, of course, it requires modernization. Leading to gas generators has always been the Perm KB. As part of the rotating nozzle best solutions offered by Klimov. we talk about the so-called hot engine parts, there is undoubtedly a leader "Saturn". In the cold part is of interest of use in the Moscow Salyut. Engine of the fifth generation integrates the best of what is today in Russia's engine building. - Is there a clear understanding of what this engine will be different from the power plants of the fourth generation? - Firstly, I want to say that some technical difficulties in creating an engine of the fifth generation, we do not see. His creation - the question time and money. The engine for the PAK FA will be different from now produced aircraft engines less weight and more traction, but still very serious actions to reduce visibility. This is the foundation. Here we do not discover America, much has been implemented in engines that are installed on the U.S. fifth generation fighter F-22 and F-35.Since we are on the path to which we have already passed our foreign colleagues, try to avoid the problems they faced when developing these engines. - They say that the most important feature of the engine is the fifth generation supersonic cruising. - I must say, our engine, I mean the 117S, is already providing such a regime.The main task for the engine of the fifth generation - to provide quality higher performance for fuel consumption and thrust characteristics, as well as the thermal signature. - At the MAKS-2009 was signed a contract to supply Russia's Air Force 48 Su-35 with engines 117S. Will this order loading of military production "Saturn" before the engine will be the fifth generation? - Of course, we are very glad that Russia's Air Force finally began to buy modern aircraft, moreover, equipped with our engines. But I should note that downloading so many engines or for "Saturn" or for the Ufa Engine Industrial Association is not decisive.She does a lot of money, although, of course, support any part of production, employment, production of military engines. - By the way, how do you assess the prospects for advancing the Su-35 for export? Passed a information about that to this car show serious interest in many foreign customers, notably China. - We do not sell airplanes, our business - the engine.But sure, the Su-35 will be in demand not only Russia's Air Force, but also foreign customers. And if they contracted the aircraft, the supply of engines, we will provide. - Can the engine 117S apply not only to the Su-35, but on other machines? - Of course it can. First, the planes that use engine AL-31F.As well as foreign cars.It's no secret that our Chinese partners are developing aircraft with engines like the AL-31F. But again this is not for us to decide where to sell our engines. There is a special state intermediary in the person of Rosoboronexport. We only participate in the negotiations in terms of technology, providing consulting services. - And what about the execution of the contract to build India's new aviation engine AL-55? The engine is created, it flies the plane HJT-36. Of course, there are certain issues of technical nature, faced by virtually all producers of aircraft engines, but they can be solved.We, together with UMPO, our partner in this project, now working to increase engine life. For example, AL-55 Saturn revealed as soon as possible with a sheet, in a relatively short time, using the latest technology, to create a new engine. The challenge now is to provide customization and mass production of the new engine. Hope we would get. - Expressed interest in whether the engine AL-55 Russia's aircraft manufacturers? - This engine can be installed on the MiG-AT, but the fact is that Russia's Air Force as a major educational and military aircraft have chosen, as is known, Yak-130, which uses a slightly different engine. However, if the customer, the problems with the delivery of the engine will not. Engine of such dimension as the AL-55 now there is not only in Russia but also worldwide. - Whether to continue the "Saturn" works on the program creation engine Burlak intended for remotorizatsii military transport aircraft IL-76 family? - Burlak - the engine is really interesting, especially as it is developed in a relatively small money. But, unfortunately, we do not see a market for this engine.The fact that Park Il-76 tankers and Il-78 is reduced. Our military customers have sufficient number of spare engines for these aircraft, and proposals for the installation of IL-76 engines Burlak of them has yet been received. In addition, as we know, there is the decision to establish on the basis of IL-76 new variant of the Ilyushin Il-76MF aircraft engine PS-90A. And here is the corporate policy, beyond which we will not leave. Nevertheless, work on the program Burlak maintained, they are not curtailed, but a lot of money for the project until firm orders the company to spend will not. - And what dividends you expect from your main project in the field of civil aviation engine - SaM146 engine for Russia's new regional jet Sukhoi Superjet 100? - Design and manufacture of such an engine as SaM146 - a costly thing, big business in it yet no one had done that, and run a lot of money on this project, we are not waiting. value is different: we are very close to Western technology, learned how to work with them.No design bureau, no engine manufacturing company in Russia, except Saturn, this experience does not. We had a fundamental restructuring of the company under the production of experimental engines - today we are up to ten items. And most importantly, that people who are working on a program SaM146 can and other engine-enterprises through corporate universities JDC train their colleagues on how to design and produce engines by Western standards, where most other canons of reliability and other characteristics. Our specialists have been trained in France, Germany, Japan, is well mastered the most modern Western equipment.Unfortunately, the domestic machine tool industry is in decline and, frankly, its just not there. Therefore we have to use Western equipment.And this - programming, digital production, etc. As a result, Saturn has come to an entirely new production. - "Saturn" will ensure timely supply of engines for the Superjet? - We have a schedule, which determined that the certification of the engine should be completed in November. Let's proceed from that. Today it is definitely possible to say that the engine failed.It flies well, confirms all the declared characteristics and noise, and fuel efficiency. No technical problems there.The main task now - as soon as possible to certify and deploy a full-scale production. - Does the "Saturn" for the necessary financial resources? Promised by the Government of 5,2 billion rubles, which will be included in the charter capital, will come later. State provided us loans through Vneshtorgbank. We have completely bought all the necessary equipment for the next year, in preparation of production capacities, which will be made parts of the engine SaM146. - "Saturn", as is known, except for aircraft engines, is developing a gas turbine units for marine equipment and engines for cruise missiles.How are things going here? - Sea theme, we plan to engage in the future. We expect that soon will arrive in Rybinsk Navy Commander Admiral Vladimir Vysotsky, to see our capabilities and to understand what has been done.After his visit, we will set your volume orders and deliveries. I would like to note that this is - dual engines. They may also apply to the civil courts. As for rocket engines and engines for unmanned aerial vehicles, then this theme in "Saturn" also remains. Previously, these engines were made at the Ukrainian company "Motor Sich". Several years ago, their serial production was mastered at the "Saturn".No problems with their production there. Of course, such episodes, which were earlier, when several thousand were produced by the engines a year, today there.But even if it is carried on 200 - 250 pieces - is also good. - What are the prospects for "Saturn" on the roar of gas pumping units and power plants established on the basis of gas turbine engines? - This is the most promising topics from a business standpoint.Here we see the basic earnings, basic earnings, which will guide the development of new engines, the development of the enterprise. Great attention to this direction in the domestic engine-paid executives OPK Oboronprom and GC Rostekhnologii, which provides all possible assistance and support. For the engine is very important to have large volumes.No volumes - no engine, but here everything will be. Creating energy turbine units - a very promising business.In addition to electricity, it is also a secondary heat, which, through exhaust-heat boilers can be used to heat homes and industrial buildings. Modern gas turbines - a very cost-effective and far more profitable than many other settings. At JDC has a number of pilot projects with a number of regions that we do not wish to disclose.This will be done later, but believe me, their implementation will bring a lot of money. Including for "Saturn". Our subsidiary company "Saturn - Gas turbines" is defined by the general contractor for the construction of power facilities JDC turnkey-based gas turbine units - What do you see the role and place of Saturn in the United corporations new engine? - "Saturn" - JDC principal place of business - with the strongest design bureau and promising for developing the plant, which is now rebuilt, modernized. As a result, it will be new production. In our view, the "Saturn" within the JDC is one of the best prospects. The company is very diversified. It developed and produced a wide range of different gas turbine engines.That - and the rockets, and aircraft engines for military and civil aviation and maritime theme, and gas turbine capacity to 145 megawatts. In "Saturn" is a very good test base, which no one else. Industrial policy "Saturn" in this sense simply perfect.For such enterprises as "Saturn" - the future.

Secret Russian fighter now collect dismissed "designers" Izhevsk car factory Strange situation at the plant, which produces fifth-generation fighter PAK-FA. On responsible aviasborku thrown urgently working with the bankrupt Izhevsk factory - until recently they were doing anything but not the aviation industry. The initiator of human rokirovok called the factory administration. According VPK.name, it is possible that the creation of a super secret PAK-FA and the airliner Superjet-100 "will now oversee the master Izhevsk OOO Region-operation.Meanwhile grand dismissal 3 thousand people are expected at another town-forming enterprise Komsomolsk-on-Amur - Amur shipyard. The fact of the arrival in Komsomolsk-na-Amur Aircraft Production Association KnAAPO fourteen machinists from Izhevsk has caused mixed reactions among the "gagarintsev, accustomed in recent years, a massive release of the company's own personnel. Enormous responsibility before the country, which took the manufacturer Superjet-100 "and the PAK FA - KnAAPO at the air show MAKS-2009", will soon be affected by the visitors milling machine and turners-rastochniki. For example, according to a recent order of Director General Alexander aviaobedineniya Pekarsha, labor "migrants" from Izhevsk (probably a shortened working bankrupt Udmurt plants) to produce Air Technical details of 11 hours per day at 6-day working week, under the direct supervision of an authorized representative, Wizard of Izhevsk OOO Region-operation. Thus the responsibility for damage to equipment or manufacture of substandard aviadetaley assigned to the existing shop chiefs KnAAPO. Meanwhile, the factory administration, in its new personnel policy does not see anything strange.According to Mr. Pekarsha, such a schedule due to sharply rising, a portfolio of firm orders and an increase in KnAAPO defense contracts. According to the senior managers Sukhoi, the only way to realize the data to the state and private airlines promise.
