The engine of the second stage for the PAK FA brought to ground tests

81
In the framework of the program “Perspective aviation Frontline Aviation Complex ”(PAK FA), the domestic defense industry must create not only a new fifth-generation fighter, but also a number of different products necessary for its construction. A few days ago, there were reports on the ongoing work on the project of a promising turbojet engine for the PAK FA aircraft.

New reports on the project were published by TASS news agency 2 September. During the Eastern Economic Forum, the agency’s journalists were able to obtain new information from the general director of the Komsomolsk-on-Amur Aviation Plant (KnAAZ). Yu.A. Gagarin Alexander Pekarsha. The head of the company said that the second-turn engine for the PAK FA aircraft is already up and running. Currently, the tests are going according to plan. Other data on current work, however, was not disclosed.





Shortly before the information about the work on the engine appeared, the responsible persons announced the possible course of further events. On the eve of the opening of the Eastern Economic Forum, the Governor of the Khabarovsk Territory, Vyacheslav Shport, said that the mass production of aviation technology could begin at the end of 2017. Fighters of the new model will be included in the state defense order for 2018 year. The aircraft factory in Komsomolsk-on-Amur will be the site for the construction of the PAK FA aircraft.

Recent progress reports on the engine for a promising fighter may be cause for optimism. Conducting ongoing tests brings the time of installation of new products on experienced aircraft, followed by testing in the air. In addition, these works open the way for full-scale production of full-scale aircraft capable of showing all the calculated characteristics.

Recall, in connection with some features of the development of promising power plants, it was decided to use several types of engines in the framework of the PAK FA project. Initially, the experimental T-50 aircraft received a so-called. engines of the first stage - they were products of AL-41F1. After the appearance of the new engine so-called. the second stage, having the required characteristics, it was planned to introduce it into the project. At some stages of the PAK FA program, first-phase engines were considered not only as a means capable of testing, but were also offered in the context of the construction of the first production aircraft. The engines of the second stage, in turn, should have been installed on serial equipment in the future.

Currently, the T-50 aircraft are equipped with engines of the first stage of the type AL-41Ф1 or “Product 117”. Such engines are based on existing developments, however, the vast majority of components and assemblies were designed specifically for them. Characteristic features of the technical appearance of the engines are a larger diameter compressor, all-view thrust vector control and an automatic control system with full responsibility. In the afterburner mode, the engine “Product 117” can develop thrust up to 15000 kgf. It also differs from its predecessors by increased resource up to 4 thousand hours and reduced fuel consumption.

The AL-41F1 engines have been mass-produced for several years. In addition, the production of products AL-41F1C, designed for serial fighter Su-35C. They differ from engines for T-50 fighter jets by some design features and equipment. The main features remain, including thrust vector control, but the maximum thrust is reduced by 500 kgf. In addition, instead of the newest electronic control system, a time-tested electromechanical is applied.

In the future, the fifth-generation fighter will have to get new turbojet engines, now known under the designation "Product 30". In accordance with the terms of reference, such a power plant must develop a thrust of at least 16000 kgf, and also use the most modern practices in various fields. Creation of the “30 Product” was entrusted to the United Engine Corporation, namely its “combat aircraft engines” division. The head developer, coordinating the work of all enterprises-performers, was appointed OKB. A.M. Cradles, which is a branch of the Ufa Engine-Building Production Association. Some other organizations and enterprises are also involved in the work. Serial production of promising products is expected to expand in Ufa.

The development of the 30 product project was completed last year. During the aerospace exhibition in Le Bourget, representatives of the Russian industry told about the completion of the technical design of the new engine. As of mid-June 2015, the project was at the stage of preparing the technical documentation necessary for the manufacture of experimental products. By the end of the year it was planned to assemble two engine demonstrators. At that time, all work was carried out in accordance with the established schedule.

In March, 2016, the representatives of the head developer again talked about current work. It was mentioned that the prototype of the new engine is still in production. At the same time, tests of the internal contour of the product, made in the form of a separate unit, were conducted. A complete prototype of the “30 Products” was planned to be sent for testing in the summer.

According to the latest reports of representatives of the defense industry, the so-called. the engine of the second stage has already begun testing on the ground stand. For some next time, inspections of this product should be completed, the results of which will address the issue of installing new types of engines on experienced aircraft with subsequent tests of equipment in the air. Apparently, all these works will be carried out in this and next years.

The exact timing of the completion of work on the new engine and the deployment of its mass production in order to equip promising aircraft technology has not yet been specified. Last year, aviation industry representatives mentioned that development work on the “30 Product” would continue until the 2020 year. Shortly before that, in December 2014, the Director General of the United Engine Corporation, Vladislav Masalov, pointed out the possibility of carrying out the first flight of the T-50 with the engine of the second stage in 2017. In November last year, new information on this matter. According to the statement of UDC Deputy General Designer Viktor Belousov, the first flight of the aircraft with the new powerplant will occur only in the 2018 year.


Exhibition sample engine AL-41F1С


The emergence of serial engines of the new model with the required parameters will give promising fifth-generation fighters the opportunity to demonstrate the basic characteristics at the required level. First of all, there should be an increase in speed, range and other flight characteristics. In addition, an increase in thrust can be used to increase the combat load with corresponding consequences for the effectiveness of the use of technology.

According to various estimates, the normal take-off weight of the T-50 aircraft will be within 30 t, the maximum - up to 37 t. With these weights, two engines of at least 16000 kgf will be able to provide thrust-bearing capacity of at least 0,85, depending on the payload and fuel stock . At the same time, in some cases this parameter will exceed one, which will give appreciable advantages over existing and prospective aircraft. For example, the expected acceleration to high supersonic speeds without the need for afterburner. As a result, the promising fighter will differ from other aviation technology with lower fuel consumption, which should have a positive impact on the range.

At present, six flight prototypes of the T-50 aircraft are involved in the PAK FA test program. All of them are currently equipped with engines of the first stage of the AL-41F1. In the foreseeable future it is planned to build several new prototypes, which will also participate in the tests. The features of a complete set of new equipment have not yet been officially specified, but there is reason to believe that some new cars in the future will be able to get engines of the second stage. Testing of such technology, according to the latest data, will begin only in 2018 year.

From the available information about the engines it follows that the first production aircraft of the new model, as planned earlier, will be completed with engines of the first stage. "Products 30", apparently, will be installed only on the technique of later releases. According to the latest plans of the Ministry of Defense, by the end of this decade, the aviation industry will have to release and transfer to the customer more than fifty T-50 aircraft. How many vehicles will receive new engines is not yet clear.

The development of a new engine is one of the most difficult components of the program "Advanced Aviation Complex of Frontal Aviation", which, in particular, is expressed in the regular revision of the deadlines for the implementation of certain works. Nevertheless, by now the engine of the second stage has been brought up to the stage of ground tests, which approximates the following checks. Completion of ongoing work, in turn, will bring the moment of installation of pilot engines on prototype aircraft. Therefore, in the foreseeable future, new messages should be expected both on the progress of the PAK FA program as a whole and on individual projects within it.

In the world of countries capable of creating an aircraft engine that meets modern requirements, there are not many, or to be more precise, it has been implemented only by the United States so far, and having created an engine for the T-50, we automatically fall into the "elite club" of which only we and them.

      Yes, about the "product 30" silence is generally akin to deathly. On the one hand it’s good. It testifies that the work is proceeding tightly, under very tight control and not unsuccessfully. On the other hand - it is clear that in spite of all the problems there are still - the deadlines, at least a little, but significantly go right.

        There is a rational meaning. Another question is that there is no engine as such yet. And such remotorization is possible 5 years after the start of serial production of the T-50. Until the engine is finally brought to mind, it will be relieved of all childhood diseases and so on. It is more economical, longer overhaul interval and so on. The meaning is, of course. But first, you must at least wait for the engine itself. And he has not even passed ground tests, judging by the leaking information.

        High thrust-to-weight ratio (close to one in afterburner mode and more than one in afterburner) is one of the signs of the fifth generation aircraft. While the thrust-weight ratio of the T-50 with AL-41F1 is slightly worse than the F-22 with F-119, the new engine is designed to pull this parameter up to a confident 5 generation. The fact that someone throws a hat on the 20 000 kgs does not eliminate the need for a realistic (up to 18 000 kgs on the afterburner) to increase the thrust-weight ratio of the PAK FA (only to 1,1 on the afterburner with the maximum take-off weight).

    According to various estimates, the normal take-off mass of the T-50 aircraft will be within 30 tons, and the maximum - up to 37 tons. With these weights, two engines with a thrust of at least 16000 kgs can provide a thrust-weight ratio of at least 0,85, depending on the payload and fuel supply

    And why rejoice? SU-27 has even better thrust-to-weight ratio. Maybe a mistake in the numbers?

      This is the thrust-weight ratio with the maximum take-off weight; for comparison, the F-22 has 0.83.
      And with a normal take-off weight of 1.36, i.e. the T-50 with the engine of the 2nd stage will have a 25-30% thrust ratio higher than other fighters in the world and 10% higher than the F-22.

    There are various versions in the public domain about the maximum thrust of an 30 product on afterburner (from 16 to 18 tons) and without afterburner (from 12 to 14 tons). It is possible that this refers to the characteristics of the first batch and the subsequent ones after fine-tuning the 30 product in operation.

    In any case, a pair of new engines will provide the T-50 in close-to-air combat with a thrust-weight ratio of more than one (with normal take-off weight of 30 tons), cruising supersonic flight in off-line mode, maximum speed 2,5 M, maximum take-off weight 40 tons (when working on ground and surface targets) and 8000 km ferry range (with hanging tanks).

        In general, this is a direct application of the theory of heat engines ... In general, to ensure supersonic speed, it is necessary to provide a supersonic outflow of the jet. FK provides this with a relatively simple method - we increase the temperature behind the turbine. At the same time, we have a relatively simple gas path, and it is not difficult to ensure the stability of the gas flow ... (by the way, it is for this reason that for a very long time they could not solve the problem of FC in rotary nozzles for "vertical" - the probability of pressure fluctuations and flow stalling when changing the geometry of the exhaust tract - i.e. the interfacing of the parameters of the fuel automation is complicated by several orders of magnitude)
        In the case of afterburner supersonic, at least a part of the compressor - turbine duct must be made with reference to the supersonic speeds of the gas flow, and it must also have a huge reserve of gasdynamic stability - otherwise surging is inevitable. Those. the nozzle apparatus of the compressor and turbine should have at least a variable geometry, while the mechanisms that provide this change should have tremendous speed and work flawlessly withstanding enormous thermal and mechanical loads ... At the same time, the weight of the rotor should not increase noticeably ... In general, there work and metallurgists and engineers ... At the same time, this is pure mechanics - electronics is not at all involved here ...

            On Al 7 there is no supersonic flow of the jet in the main path, where the compressor blades rotate at supersonic speeds. This is a matter of blade profiling - aerodynamics. - and the main gas flow there moves as elsewhere on the sound. At Al 7 (if I remember correctly, I was teaching for a long time), the controlled nozzle apparatus in the compressor and the air bypass system were first used to increase gas-dynamic stability ...

            And about the "frontal solution" - so from the point of view of TAD any solution is "frontal" the formula is simple / air flow rate per square of speed / - another question is how to implement this simplicity ... flow (and, most importantly, its change) in such a complex object as the gas tract of a turbojet engine .... Probably and in principle it became possible to create such models quite recently ... When the computing power allowed ... you cannot calculate this on a slide rule ... through trial and error, decades of work and incredible resources ...

      And then they only look for the corruption component in the articles and do not get any more information from there.

    16000 kgf is more than two engines from the MiG-29! You can start designing a lightweight fighter with the 1 generation 5 engine ...

    ... we will not have single-engine manned aircraft - there will be no such requirements.

      T-50 mass aircraft can not be expensive. If they make 100-maximum-200 it will be very good. Now and about 20 years later, the role of mass fighters will be played by the Su-27/30/34/35 and MiG-29/35. In theory, now we need to start a program of light / medium - the main tactical fighter of the Air Force. The main systems in the form of materials, radar, electronics, drives thanks to the T-50 program will be. In the case of one engine, the engine will also be. Consequently, the program becomes cheaper and faster. in the case of two engines, this is anew development of the engine with all the tests and then the problem of maintaining the production of engines for the T-50. For me, the standard of unification of the F-16 and F-15 engine is one ...

    The article indicates progress in the front, and you pull back.

    Even the thought was not such as to pull someone back. Well, the company launders Sukhoi budget babalosy, so is she alone? Quite often, this process is going on at all levels. Of course, fighters of the 4 ++ generation are good, but I would like to see something like the 5th generation fighter in service. Why initially had engines that did not match his status as a 5th generation fighter be thrown at him? An incomprehensible concept of the Sukhoi firm, on the principle that it was something that they put in? But these are budget funds, if there were a private trader, God be with him.

      Umka. . . If you imagine the whole process not as something new, but as two screws to twist, THEN YES YOU RIGHT. . . and you only need to talk about theft.

      Here's another example for you:

      Eh, it's a pity that you can't look through the documentation ... Non-afterburner supersonic ... Even having a specialization in "SD" I can hardly imagine the technical implementation of such a parameter. The nozzle apparatus and control system of such an engine must be something fantastic ...

        If they could immediately launch a super engine into production, then they probably would have done so, and did not start restoring all production chains that were destroyed or simply cut-down versions were bought abroad.
        And if you assume that there is no engine then you didn’t need to launch the project, then we would not have reached the 7th generation. It is clear, after all, that this was the best option. It is not for nothing that the Americans stopped the production of the Raptor and now conjure over the 35th family. Dear pleasure, new generation. Everyone is trying to make the best quality price.
        And with theft Who is to blame and what to do is a completely different story. I am glad that they are engaged. . . we need to talk about this, new technologies to the masses, so to speak. If God forbid, this question will be resolved.

      The practice of installing existing engines with the installation of standard engines in the future has been practiced for a long time and this is absolutely normal. And, in some cases, even
      the only option. During the creation of a full-time engine, you can work out
      BRO, aerodynamics, etc. Example M-50, F-104, A-12 (SR-71) .....

    The head of the enterprise said that the second-stage engine for the PAK FA aircraft is already ready and running.
    I don’t understand why work is going so slowly
    a year ago they said the same thing - that there is a poster sample that is already being tested.
    Something again lies, but I don’t understand.

      Yes, because these are new breakthrough technologies and it is very difficult to debug them. The combination of supersonic fuel economy and acceptable engine life.
      You won’t get off with one sledgehammer.
      How to understand this is impossible. . . what's so complicated.

    ... give the original (links) where they talked about the tests and which ones.
    Otherwise, your reasoning is interpreted as an unconfirmed flood!

    1. We sell equipment for dollars that flow abroad. We give away for free.
    2. Starting next year, the Prosecutor General’s Office of the Ministry of Defense will withdraw from the Ministry of Defense. Of course it pleases.
    3. Eastern built for int. flights. Again, politics.
    4. Engines for aircraft rockets built. It remains to find Gagarin.
    5. The Nazis will come to power just for everything ready without a single shot. Who will answer the people again. Leave to the Far East. To China.

    The article reminded me of a coursework from the university: solid water laughing
    And in fact this news has been about a week. I mentioned it last Friday or Saturday. She appeared on the "Look".
    And you don’t have to figure out how some here do that tests have long been underway. A full-scale specimen, as it were, in metal has not yet been in the press.
    Another funny thing is that Bondarev talked about the engine in '28. In short, the guy can not get to the point in any way: then everything is straight from him soon and already serial in the troops. then after 100 years. Not a ditch straight.

    Blackmokona,
    Fights in Red Flag are conducted strictly according to American rules: airplane versus airplane, pair versus pair.

    The Americans at Red Flag 2008 had two handicaps: they used AWACS and banned the Indians from using on-board / overhead electronic warfare systems. In response, the Indians achieved for themselves the only handicap - not to use the AIM-120 missiles from the American side.

    As of the 2016 year, this is no longer required either - the RVV-DB has a range of 75 km for the highly maneuverable target, and the golimnaya AIM-120D has only 45 km.

    Whining "Predator" ( laughing ) from under the shop for 8 years only intensified.

        AMRAAM makes a confident capture no more than from a distance of 40-45 km, while in the yaw angle sector no more than 30 degrees, the R-77 with the active operation of the GOS captures 70 percent yaw at a distance of 70-80 km, this is currently the record, the only thing that will be the electronic warfare is the counteraction !!!

    Yes, really? It’s done, you need to stretch a couple more years and you can close the project as morally obsolete. And that's all, the money has been spent, cut, the fact of innovation is indicated. You can proceed to the next cut and puffing. And we also have Mig-23 for drying and meat there is. Even if in a couple of years they knock him to acceptable parameters, finally, how many years will they build, at least 1 squadron (which is nothing at all)? And how many similar partners will have by this time? Is all this the result of our educational and the educational system and the personnel management system. In order to create something, one must begin by creating (or rather restoring) the education system, the monetary system and the government with the strict (or rather cruel) responsibility of those responsible for decisions made and various endless reforms, with destructive strategic consequences for the state, especially starting with primary education and upbringing (the foundation of our future), namely upbringing, a rigid planned economy.

      Having penetrated the polymers? How many of you got divorced everywhere ... The Japanese are just making the first flying model - we have such a model took to the air in 2010. The Swedes, too, something about the 5th generation has just begun to sculpt. The beginning of your post is the cry of Yaroslavna, honestly. Already pulled into the opera. Original to listen. And then from mediocre rehashings already troubled.
      I hope that our partners will not have similar equipment for a very long time. All the same, what ours is laying in the PAK FA ... It is quite possible their 6th generation will politely give way. The engine would have to wait ... By the way, it was decided to form a squadron of T-50 engines with the first stage. But you obviously have not heard about this, although the "news" has been around for six months now.
      However, near the end of the post thoughts are not bad, even quite sensible come across. Yes, a lot needs to be restored or rebuilt. What to do - we destroyed our country again, once again.
