The United Engine Corporation (UEC) has completed bench tests of an experienced AL-41F-1 turbojet engine for the newest Su-57 fighter aircraft, the corporation said.


The final meeting of the state commission on the AL-41F-1 turbojet engine ended with a solemn presentation of the certificate of completion of the state bench test of the test engine to the “UEC-Ufa Engine-Building Production Association”
- TASS reports the press service of the corporation.

Commission adopted. Development work on AL-41F-1 completed


They reported that with the end of the bench tests completed 14-year experimental development work. The AL-41F-1 performs the function of a first-stage engine for a fifth-generation fighter.

The Su-57 fighter program (PAK FA) provides for the creation of the first production models with the first-stage AL-41F-1 engine. From the engine for the Su-35С (product 117С) it is distinguished by an increased thrust force, a complex automation system, a fully digital control system, a new turbine, and improved flow characteristics.

Currently, the UEC is working on the engine of the second stage for the Su-57. 5 December 2017, the aircraft with the engine of the second stage for the first time rose into the sky, the flight took place in normal mode. When creating a promising engine, the latest technologies and materials have been applied, the use of which has made it possible to achieve the technical requirements for the fifth-generation propulsion system
- stated in the corporation.

Recall, 6 January 2018, the tenth prototype of the fifth-generation fighter Su-57 (PAK FA) began flight tests, until that time, nine PAK FA samples with the "first stage" engine participated in the tests. December 5 2017, the first flight of the newest fighter with an engine 2-th stage, reports "The View"

    Fine!!! But, nevertheless, everyone has already been waiting for the engine of the second stage. It is time to see it and "feel" it ... And also, as it seems to the amateur, it urgently needs a fifth-generation single-engine fighter. China is trying to sculpt such a miracle. If he succeeds, the market for the aircraft will be simply huge. And why lose what we ourselves can do, and even better ...

          You are mistaken dear. Since the beginning of the 80s, work was underway on the ed. 20. For Mig 1,44. These are completely different motors. They have in common only the creators (Design Bureau named after A. Lyulka) and the scheme (DTRDF).

            A comma is placed before the "respected". I admit my mistake. It was necessary to read Wikipedia school) Al-41F1 (product 117) - not a stub from Al-41F, but a completely new engine that has no analogues in the world. Like in the Su-57 itself, it does not use Soviet developments.

              No, not a stub ... Maybe we don’t understand each other, but - rather, it’s a “soooooooooooo” modernization of the AL31-FP. As I said earlier ed. 20 is a completely different engine, well, it will not fit in the T-50, at least crack (glider). It is larger than 117-shki both in the midsection and in length.

                  Not bench tests but R&D were completed. Each new engine, even after the completion of the R&D, passes acceptance tests (also bench tests).

                  The list of development work includes, including bench tests, one of them, confirmation of the resource, MTBF. This type of test is the longest. The engine operates in various modes, according to a cyclic test program. In the R&D process, flight hours are assigned to aircraft engines, confirmed by ground-based engine tests. If the flight engine has exhausted the assigned (authorized) hours, it is "slowed down" on the ground, until the resource is extended - the achievement of another milestone at the stand ... Somehow)))

          work does not end there - different projects are accumulated in the form of experience
          and each project is a prelude to the next.
          As for the terms, I think that at least half of the delays are due to untimely financing of work on the right scale, and the second half is a low degree of concentration of work and the composition of the environment of specialists. Too few jobs in this industry, too few people are doing this, too few fixed assets exist in the industry.

        - fifth generation airplane?

        The engine of the first stage meets all the requirements of a new generation of fighters. And there is no afterburner supersound. It differs from the dvigun of the second stage in that the product 30 is more economical (about 15%), its resource is higher, and the thrust will probably be more.

          It is interesting to compare the level of manufacturability with the F-35 engine
          product 30 is still noticeably inferior in power to this engine
          and only a couple looks decent, and the dimensions are comparable.

            Often I see how people use the expression `` manufacturability '', `` level of manufacturability '', endowing them with specific, meaningful meaning only to them. Often they simply interbreed 2 different concepts: `` manufacturability (in production) "and` `technical level (of the product) ''. The first determines the degree of fitness of a given product for production by this particular production (and no more). And the second is much a broader concept (which includes the first definition): a set of output technical characteristics laid down by designers at the development stage + the ability to provide these parameters in a specific serial production + ensuring the required level of quality, reliability and resource.

              So, when a person associated with the production of something sees a similar use by people of technical terms incomprehensible to them (no matter who: journalists, forum users, various other `` analysts ''), then he experiences a slight dissonance that prevents him from giving a brief, and the answer obvious to him, without going into various kinds of educational programs ..

              Actually, I meant all of the above and I understand the essence of the term.
              I want to understand at what technological level engine building is
              and how does this compare with the Americans.
              For example, Americans began to actively implement SAP for development 30 years ago
              in our country, such attempts began locally in the 90s, but brought few results
              and real automation began recently, and this technology is already a quantum leap in design.

          The question of the efficiency of new engines is actually very interesting)) So the creators of their masterpieces in all official documents operate on specific parameters (consumption in grams per unit of developed thrust). At the same time, taking into account the increase in traction with each new generation (or with a deep modernization of the serial product), the absolute consumption is growing quite significantly ... That is, despite the declared efficiency of new power plants, aircraft developers have to increase the fuel supply on board every time ( as can be seen from the evolution of the Su-27 family: Su-27-Su-30 (Chinese version) -Su-35, and now Su-57, as a follower of glorious traditions). So everything is folding and beautiful, usually only on paper. And this applies to vehicles, and armored vehicles, and ships. Miracles in modern technology, something is not observed yet)))

            what kind of efficiency can we talk about if the requirements for engine thrust have increased 23 times since the moment of mig-3? All that remains is to operate with "efficiency."

        what's the difference how many years worked?
        it must be understood that in addition to the engine design itself (which could have already been developed 20 years ago), masses of parallel things, individual parts, materials, control electronics were developed, unification problems were solved, production equipment was developed, etc. etc. (The design of the engine itself is no more than 10% of developments). It’s not enough to come up with an engine, you also need to create a working sample, but nobody needs a working sample if it cannot be produced quickly, massively and at minimal cost.
        Undoubtedly, this is already a strong groundwork for future, more technological engines and machines, and not only in aviation.
        And taking into account the state of science and industry in the 90s-00s, this is generally an achievement equivalent to flights into space in the 60s.

      And also, as an amateur thinks, an urgent need for a fifth-generation single-engine fighter is urgently needed.

      In Russia, such machines have not been made for a long time. The last option was the Yak-41, which did not go into the series. And then it is conditionally single-engine. And then, the thrust-weight ratio of a twin-engine machine is always higher than the single-engine version. What is the benefit then?

          For export, it is undoubtedly important. However, using the example of lightning, you can very well understand the intricacies of such relationships ...
          Take a look. The States designed the Raptor and manufactured about 2 hundred such machines. Trumpeted to the whole world, that this is the very fighter. Nividimka and so on and so forth ... I don’t argue, the plane is interesting and somewhat innovative, but the states have refused to sell it for export, even to the most allies. Although willing, more than enough. Even today, the Yapis show their interest in the F-22. Next is the knight's move. The states told their allies that since you really want to, we have the technology and all that, and with your help we can create at least “cool” Lightning. But it will be cheaper, and will have a bunch of chips, which, as it turned out, are not needed. Here you have the export. Chet pulled on demagoguery.
          I mean, give the same Yapam the opportunity to choose which of the planes they would buy the F-35 or F-22, I think that the choice will not be in favor of lightning ...

            F-22 is faster and more powerful, it is a fighter of gaining air supremacy with strategic capabilities to quietly seep through air defense.
            But he has the remaining avionics of the 80s that does not allow, for example, to integrate with ground forces.
            F-35 - drummer with the capabilities of a fighter. He cannot work as an interceptor. But he has wound avionics: universal capabilities of any
            network integration with anyone, drone control, electronic reconnaissance, electronic warfare ...
            Naturally, it is better to have both types of aircraft in the Air Force (combined 1 to 4 approximately, a quarter of the Raptors, 3/4 Lightings)

              it is a fighter of gaining dominance in the air with strategic capabilities to quietly seep through air defense.

              it may be able to leak, but it certainly won’t return:
              all strategic F-22 is broken on its small radius of action.
              And additional tanks turn it into an unsuccessful clone of the F-15.
              It seems to me that Israel can approach F-22 with its distances, but it’s somehow not even worth talking about its strategic use.
              But Japan F-22 why - I do not understand. He is capable of working there only as a purely defensive air defense interceptor again because of the fuel supply and all his stealth will not be in demand.

              Yes, he argues! Only at this level of manufacturability does it make sense to develop a product for specific customer requirements. If it is simpler, then - do we need a single-engine aircraft? More likely no than yes. Reliability is lower, thrust-to-weight ratio is lower, maneuverability ... i.e. the aircraft should be created for the needs of a foreign customer, and this is TK and other. There will be such candidates, our plane will certainly make ours. T-50, by the way, doesn’t seem to be being exported))) But the Hindus are going to refuse their joint project, expensive.

                the Indians have recently flown with a contract for the purchase of aircraft due to bargaining, having concluded and terminated the contract with the French.
                And now they are confidently going there too. It makes no sense at all costs to hold on to cooperation - it should be mutually beneficial.
                But in order to sell light fighters in large quantities, like Mig-21, the military-industrial complex still needs to be done. It would be great to repeat the success of the F-5 now.

      Foremost hi - The Chinese will create their engine only if we help them very much! It is impossible from scratch, not having your own design school, even the fourth generation engine to create! Everything the Chinese do is just copies. And very far from the original! They are sorely lacking in knowledge and technology!

      The engine of the first stage is quite suitable for future modernization of the Su-27, Su-30, Su-33, Su-34. As well as foreign counterparts. There are AL-31 everywhere with traction from 12 to 13 tons. The new engine delivers tons on the afterburner 14-15, plus improved resource, efficiency, etc. A good increase in power.
      Everything will come in handy on the farm.

          But in Su-35, how did they install it the same way? They will make a new version with some sort of index and forward. Or in general, you can install them immediately on new aircraft, rework the fuselage for a new engine. It seems to me for the Su-34 and Su-33 especially, an extra couple of tons of traction will come in handy.

            In the Su-35, they installed it only because the Su-35 was originally designed for it! And for remotorization by this engine of an aircraft of the Su-27 family, at least alteration of the engine mount is required (the overall dimensions of the engines grow with increasing thrust - there are no miracles in technology). Now imagine, you need to cut off the entire tail section from the aircraft (this is a structural element of the structure, by the way)), design a new one, conduct the entire test cycle (both for life and flight). Question: does someone subscribe to this in their right mind? (We are still not "great shavens" - sometimes they didn’t do that)))

              (with the increase in traction, the overall dimensions of the engines also grow - there are no miracles in technology)

              In fact, not always. For example, one of the ways to increase traction (it’s also the main one) is to increase the air flow through the engine and this does not always lead to an increase in the outer diameter of the low pressure and high pressure valves.

              What size have they (overall dimensions) changed? Believe me, until I see special problems, make small changes to the engine nacelle when changing the diameter of the low-pressure valve in an extra pair of tens of millimeters.
              It is much more significant that, with an increase in traction characteristics, the power structure of the airframe may lack strength ... Thus, no one will modify the airframes already manufactured, and the Su-35 can be manufactured again (airframe, well, stuffing if there is enough money) .. .

          But was the engine designed for a specific glider?
          In any case, there are restrictions on dimensions and weight
          I think the confusion was caused by the fact that the product 30 was delayed for at least 5 years and it turned out that the glider began to fly before the engine. But I am sure that the glider was created looking back at the preliminary requirements for the engine, and not vice versa.

    Well, it’s good, after 14 years of development to make an engine.

    But the question is, how many years to wait for the “native” engine, the 2nd stage for the Su-57, is it really 14 years?

    With all due respect to this result, it must be understood that the Indians will not take the Su-57 with 41 engines.

    The fate of the MS-21 also depends on the engine, on the new (already 15 years old) PD-14, and behind it the PD-35 for the Chinese and Russian long-range aircraft.

    Even for the An-2, you have to take the engines from the adversary.

      Here you read here "great specialists" in aircraft technology, and especially in aircraft engines, and you are fucking crazy.

      "But the question is, how many years to wait for the" native "engine, the 2nd stage for the Su-57, is it really 14 years?" - why do you need the engine of the second stage?!?! maybe you need to turn on your head even for a minute, and ask a simple question - according to which parameter the SU-57 with the engines of the so-called "first stage" does not meet the parameters of the generation aircraft?!?! Can you find at least ???
      "With all due respect to this result, we must understand that the Indians will not take the Su-57 with 41 engines." - Thank you for respecting the result of our engineers and designers, I hope this is sincerely !!!! yes But here again, you need to turn on your head even for a minute - the "Indians" may want something or not want to, take it or not take it - and when did our people give it for export without having a better one ?! Or it, this is the best already, or technically cut for the export of existing TTX. Therefore, Al-41F1 will go to the "Indians" - it meets all the parameters of engines for aircraft of the 5th generation.

      "The Engineering School of Russia is in a Crisis State" - How I Like All-Singer laughing the more such screams - the better things are with us wassat
      Firstly, we have the best engine in the world for aircraft of the 5th generation Al-41F1, and the other day he completed a full cycle of state and field tests on ALL parameters on the ground, in the sky (and possibly under water - we don’t know wassat ) and officially adopted.
      Secondly - we already have an even better engine - "product 30" - and it even flew laughing and it differs from the Al-41F1 only in that it is more economical, more powerful and more durable, which does not affect the parameters of the 5th generation aircraft for the performance of BATTLE (rather than operational) tasks (or almost no effect). We have something to put now on the 5th generation, we are on the way more perfect, maybe even for the 6th generation laughing
      Thirdly, with all the problems in education (which I agree by the way - you need to throw it away with a filthy broom) - we had, have and will have excellent engineering and design personnel, schools and technologies - even for 90 years we could not crush this - and now even less so - look at the Sukhoi Design Bureau, the Yakovlev Design Bureau, etc. - how many youth work there !!!!! In any situation of our country, even catastrophic, there will ALWAYS be that thousand people (or more) who will represent the color of science, engineering and design schools - Lomonosov in the bast and backward Russian Empire - went to school for 30 km, then (without a train , airplane or car) came to St. Petersburg, and became the greatest scientist and figure in the scientific world - there would be a desire good

        Based on what you said that al-41f1 is the best?
        I'm not a big specialist, but even a superficial comparison
        AL-41F1 weight 1.6, traction 8800 kgf, afterburner 15k,
        F135 weight 1.7 tons, thrust 13k / 19.5k
        It is perplexing, but in fact, what did our engine turn out to be the best?
        in terms of traction with respect to weight and size parameters, the American looks much better.
        I've tried many times to initiate discussion and comparison of these engines, but for some reason
        everyone who claims to have some knowledge shies away from this.

        in fact, only the exceptional performance characteristics of the f135 engine make the f-35 airplane not a pregnant penguin, but somehow a combat-ready machine.
