    Director General of JDC Vladislav Masalov about the prospects of Russian new generation engines

    February 18 at Bangalore International Exhibition kicked off Aero India-2015 with the participation of more than 30 Russian companies, including "United Engine Corporation" (UEC), a member of the state corporation "Rostec." CEO of UEC Vladislav Masalov told "Lente.ru" the plans for the exhibition as well as the promising developments in the coming years.

    "To Lenta.ru": Vladislav E., APC has recently been awarded a PTS, and Bangalore - the first major international exhibition for the company. What are the expectations?

    Masalov: UEC constant participant salon in Bangalore, as for us, cooperation with India is of strategic importance. But as an independent subject of military-technical cooperation (MTC) we are really here for the first time. Some time ago, the JDC was authorized to take care of engines within the PTS. Now we can conduct direct export of spare parts, spare parts and technical documentation for the previously supplied engines. We are interested not only in the increase in the supply of aircraft engines, but also in improving the speed and quality of after-sales service, building an integrated customer support system. In the future, this measure will implement strategies to create a single global service network of aircraft and helicopter engines.

    Cooperation with India realized UEC is mainly through the PTS. We supply ready-made AL-31FP engines for the Su-30MKI fighters, and breadboard. In addition, three years ago there was a long-term contract for an additional 920 engines, deliveries are to last for ten years. An important milestone in collaboration with Indian partners - the creation of the AL-55I, which is designed for installation on the first training aircraft of the Indian development and manufacturing.

    Contracts with the corporation HAL, suggest holding the ROC and the supply of AL-55I, manufactured at our facilities in Russia, as well as the subsequent organization of licensed production of these engines in India. Of work on the AL-55I aircraft for HJT-36 primary resource 300 hours completed in December 2013. Also, work is underway on the commissioning of the test stand under a license contract.

    Tell us what UEC present at this year's show?

    "United Engine Corporation" (UEC), will demonstrate a number of engines (in the form of samples and models), in particular aircraft engines RD-33 (installed on the MiG-29 SMT), the RD-33MK (installed on the MiG-29K and MiG-35) and model aircraft turbofan engines with thrust vector control, which is installed on the Su-35, as well as informational materials about their products. Information on the turbojet and gas-turbine engines of its production will provide Research and Production Association "Saturn".

    Recently there have been reports of the three points at once local production and maintenance of gas turbine power plants for ships (for replacement products and services "Zori Mashproekt"). This "Saturn", JSC "Kuznetsov" and "Ural Turbine Plant". Tell us more about how it will look on the cooperation of these products where the production will be carried out, where - after-sales service and repair, where - stands and development center?

    Import substitution program on marine "theme" we carry on "Saturn" in Rybinsk. It involves three key areas: a series of development projects for the establishment of marine gas turbine units (GTA) with our engines; technical re-equipment of production facilities, because in such volumes we used marine engines were not allowed, as well as the construction of the assembly and test facility for gas turbine engines (GTE) and the gas turbine units (GTA). That is, the "Saturn" will be the entire range of activities: the production and testing, and repair. In contrast to the issue with the import substitution of aircraft engines, here we have a complete set of technical documentation for developed engines - M75RU capacity of 7000 M70FRU capacity of 14,000, and an M-90FR capacity of 27,500 horsepower.

    Samara plant "Kuznetsov" in this program is not involved - they have a serious amount of work on the program for the Strategic Air Command. As for the "Ural Turbine Plant" (it is not included in the UEC), we are currently considering options for cooperation on maritime direction. In this project, despite the fact that a key performer is "Saturn", including many companies different departments, so the expansion of cooperation is under study.

    Since when production turboshaft engines "Klimov" for helicopters in Russia will fully replace the Ukrainian imports, while maintaining the scale of production programs helicopter?

    In the past year, "Klimov" collected the first ten engines entirely of Russian components. Therefore, it can be stated that the production of Russian engines mastered, and the task of further increasing production. While maintaining the scale of production programs helicopter we can fully replace the Ukrainian imports in 2017. In addition, now mastered the production of repair and group packages for repair TV3-117 engines in Russia.

    It was reported that in the early stages of a promising light transport aircraft Il-112B flight with engine TV7-117SM, not with TV7-117ST, as stated earlier. When the engine is ready TV7-117ST?

    We are conducting routine work to create motor TV7-117ST within the agreed terms of reference for carrying out R & D, and they hope that the first Il-112V fly with these engines. Our cooperation is defined in UEC project and the first prototypes of TV7-117ST for the initial batch of aircraft is manufactured in 2018..

    When you are ready to PD-14 engine and when it reached its readiness for mass production?

    We are now at the stage of prototype testing engine and separate units. The first half of 2015 are planned flight tests PD-14 flying laboratory IL-76LL, as well as a high-altitude test stand CIAM. Total program of engineering and certification tests will be made 14 engines. Date of receipt of the certificate IAC AR - April 2017. Next - production. On the Prototype specifications were confirmed all the basic parameters, which confirms the readiness of the engine to the special sorts of tests.

    When you are ready, "the engine of the second stage" for the fifth-generation fighter PAK-FA and how it will look on the cooperation of its release?

    Technical design of the engine of the 2nd stage for the PAK FA is made, and is currently being developed design documentation for prototyping engine. In 2015, the first engine to be made demonstrator. Work on the engine for the PAK FA are conducted in full compliance with state contract, and today we are in the chart.

    So he spells it out, no earlier than 2017 can they substitute helicopter engines from Ukraine.
    And that is assuming everything goes to plan.

    Irkut Corporation prepared documents related to development of a light strike-fighter
    Russian Aviaton » Friday February 27, 2015 14:14 MSK

    Irkut Corporation prepared documents related to development of a light strike-fighter derived from Yak-130 operational trainer for Russian Ministry of Defense, RIA Novosti reports with reference to the Senior Vice-President of Irkut Corporation, Vitaly Borodich.

    “We have prepared documentation and we are going to submit it to the Ministry of Defense. The rest is up to the customer,” Borodich said at Aero India 2015 airshow.

    Information about the possibility of developing this jet was first unveiled in 2013, it was stated that Yakovlev design bureau is considering the matter. At that Russian Ministry of Defense said earlier that a decision to abandon the project was made.

    Yak-130 is an operational trainer developed by Yakovlev design bureau. It is fitted with integrated digital control system, which provides manual and automatic flight control. The jet is also equipped with active flight safety system, which allows changing parameters of the jet’s stability and controllability during training. Yak-130 is designed for training of future pilots of fourth- and fifth-generation aircraft.

    One engine vs Twin engine aircrafts debate

    Post  victor1985 on Tue Mar 03, 2015 7:10 pm

    Whats best : a plane whit one big engine but more complex or a two engine aircraft? The two engine aircraft having the problem that has two set of swiches for engines but a lower thermal signature. And the bigger the single engine bigger the flame less materials that can be use.

    In regards to multi-role air superiority fighters, I would say multi-engine aircraft are generally preferred throught the world (the U.S. Airforce could be an exception). Both types of aircraft - in particular 4th generation aircraft - are equally complex. I've never known dual engine control to be taxing for a pilot to manage..

    As for heat signatures, I would say that's more of a concern for bombers with stealth capability - not a platform such as the Flanker.

    Two engines mean better survivability. In case one engine is off or damaged, the plane could be returned with the second engine to the base and than repaired. In single engine plane damaged or off engine mean lost plane. This is the reason RuAF made a decision, that all their planes will be twin engine and they retire all single engine planes, although some were quite new in that time (MiG-23 and MiG-27).

    Which is a good idea, I can't understand the single engine fetishists, the cost of maintaining a 2nd engine will be minimal compared to an entire plane that has crashed and been destroyed. I really hope Mig's 5th gen Mig-29 replacement isn't a single engine plane. If they make a single engine version than it should only be for export, and not for domestic use.

    What little I can find on the LMFS stipulates a single engine. That being said, I would speculate that a 5th generation MiG aircraft would be designed with naval applications in mind - that means dual engines (which are universally prefered for carrier operations - F-35C not withstanding).

    This is just my opinion, but If the 1.44 can serve as any guide, MiG will retain two engines for the Fulcrum replacement.

    It wont be a single engine, VVS has declared that they will only have 2 engine fighters in the future. Likely Fulcrum's replacement will be 2 engines, however don't rule out a single engine version for export. I should also add that single engine is ok for drones.

    LMFS existence is on a piece of paper and nothing else.

    And the VVS has ordered the MiG-35, its just MiG is unable to produce the aircraft yet because of all the subsystem delays.

    Oh yes drones, we heard that before. Because you know Mig is neck-deep in Skat drone orders.....unshaven

    But in all seriousness, the most technologically advanced drones are in U.S. inventory. One of the most advanced drones in US inventory was the RQ-170, so secretive of a project people doubted it's existence, and claimed Iran was engaging in a grand hoax. People couldn't wrap their heads around the idea that one of the most advanced drones ever created was defeated by Iran's 'Living-Fossil' of aerospace defense network (of course Autobaza made the difference).

    That fact alone is a reason you can't justify replacing a light-fighter with a drone, and just because there's no flying prototypes now doesn't mean there wont be in 5-8 years. Another fact people have to wrap their heads around is that the PAK-FA (and its derivatives) will be expensive aircraft, and only a select few countries could afford to buy and maintain them. A cheaper, lighter equivalent is necessary that will likely sell much better on the export market, and countries like Brazil, Indonesia, Egypt, Malaysia, Algeria, etc. could participate financially in the development to mitigate costs. As far as the Mig-35 goes, a large part of the slowing down of that program was the failure to win the highly politicized MRCA tender, but surprise surprise FGFA program is moving at a snails pace even though the majority of the plane has already been developed *cough, PAK-FA, cough* but is that just mere coincidence? Well it's not, just like how the lack of quality control leaves the Sukhoi fighters built in India to be more crash prone...lets stop beating around the bush and just point out that the over-reliance of the Indian export market, and it's hot-mess of a aerospace industry is a large part of the problem. Only a few countries (such as India) could actually afford PAK-FA derivative aircraft, and instead of being overly-reliant on India, they should develop a smaller cheaper alternative and a more diverse export market, so that the Russian aerospace industry doesn't lose the future 5th gen aircraft export market.

    The one engine vs two engine debate is a long debate with numerous aspects.

    In a nutshell, one engine means cheaper engine maintainence, generally lower drag because having one engine the aircraft is designed around can be smaller than an aircraft with two or more engines slung underneath. It does however mean that engine needs to be rather more powerful than if two engines were being used and lower thrust settings could be used to keep the aircraft airborne with a twin engined aircraft.

    A direct comparison of the F-16 and MiG-29 show the differences fairly clearly however the maths was muddled because early MiG-29s used Soviet maintainence practises. The replacing parts after x hours reduces inspection time but can lead to perfectly good parts being replaced which can get expensive.

    The SMT upgrades of the MiG-29 included on board testing equipment and diagnostic kit that made inspections cheaper and easier and reduced maintainence costs by a reported 40%... which is huge.

    You can do mathematical calculations in terms of weight and drag and thrust and fuel economy and pretty much unless you are wanting a VSTOL aircraft you either go with one engine or two as an optimum combination of thrust and drag and maintainence problems.

    there are no three engine fighters for a reason, though with scramjet technology that might change where a plane might have two turbojet engines to get it to mach 2 or so and then switch to a scramjet to accelerate to higher speeds.


    the F-16 needs a powerful 12+ ton thrust engine and can only reach mach 2, while the two 8 ton thrust engines on the MigG-29 allow it to get to about mach 2.3.

    With a variable intake ramp the F-16 could probably go rather faster than it does.

    well thats because doesnt matter the weight of engines. The 8 tons engine could use different fuel for example.
    And probally the two engine aircraft may be bigger but whit a powerfull thrust can be obtained same speeds inspite drag. Ofcourse that would mean probally more fuel consumption but that is not a problem if you have aircraft carriers or you are close to enemies. Also for a single engine to be more powerfull that two engine aircraft means big one engine which lead also to big aircraft. So the advantage of single engine is not so big.
    I want to ask:can be use two engines one above the other? Like they are vertically mounted?

    What about having 4 small engines around the single engine? Each of them could turn on for better maneuvers. Or small engines in front. In this the aircraft could do better in dogfights and escape missiles. Even moving angle could be added to those small engines. The engines could be put in x around single engine.

    but how does affect existence of multi engines the capabilities of aircrafts?

    An aircraft with a long operational life used in harsh environments, and possibly not getting the best maintainence attention on the front line introduces the possibility of engine failure.

    when you only have one engine then an engine failure is fatal to the aircraft and possibly also the crew... which will be expensive. Even if single aircraft only increase the loss of aircraft due to engine failure by a few percent leading to perhaps the loss of 2-3 planes over a ten year period the costs in buying new aircraft outweigh any savings in single engine designs.

    the odds on both engines failing is a small fraction of the chances of one failing... and more importantly the chance of the engine not being able to be restarted should also be included...

    I have read some studies that claim single engine aircraft are worth it because the number lost to engine failure where two engines might have made a difference is negligible.

    Of course the aircraft with the worst flight record in the Soviet military was the Yak-38 VSTOL aircraft which in theory is a single engined fighter but with two lift jets.

    the Russian military has clearly chosen twin engine conventional take off fighters instead of VSTOLs for a range of reasons... on a deck at sea even just flying your Yak-38 through some hot air from the aircrafts own jet exhaust can make engine thrust plummet and the auto eject system throw the crew out of the aircraft.

    the Harrier has killed rather more of its pilots than the Yak ever did because of the auto ejection system on the Yak, but the Harrier is a much more practical aircraft that has been rather more widely produced and deployed in real combat situations.

    Even as good as it is however the Harrier would be terribly vulnerable to MANPADS due to its side mounted engine nozzles offering an IR target from a much wider angle than most conventional aircraft.

    well thats because doesnt matter the weight of engines.

    Of course it does. A heavier engine makes the aircraft heavier and requires more power to move it around the place.

    The advantage of two engines instead of one is that the two engines can reduce demands for high power engines in a lighter over all set up.

    Going back to the F-16... you pretty much need a 12-13 ton thrust engine to get decent performance which makes it a Flanker class engine. In the MiG-29 it uses two engines that a MiG-21 might have used if it was developed a bit later in the 8 to thrust class each... but the point is that with two 8 ton thrust engines the MiG pilot has 16 tons of thrust when he needs it... a 16 ton thrust engine for the F-16 would be possible, but very expensive and likely heavy.

    I want to ask:can be use two engines one above the other? Like they are vertically mounted?

    yes, the British Lightning had that arrangement... it was a very good interceptor.

    What about having 4 small engines around the single engine? Each of them could turn on for better maneuvers. Or small engines in front. In this the aircraft could do better in dogfights and escape missiles. Even moving angle could be added to those small engines. The engines could be put in x around single engine.

    It would be cheaper and simpler to just use a more powerful main engine... for instance in the example of the F-16 then the engine from the F-35 would offer plenty of thrust, or the engine to be fitted to the PAK FA in the 18 ton thrust range would be useful for a single engine light fighter that is heavier than a late model F-16.

    Also small engines could be puf in front of aircraft. Mounted in angle so the flame not touch the plane.

    Such small engines would not add that much thrust, yet would add weight and complication with wiring and fuel lines all over the place.

    If you want to temporarily add thrust then I would suggest a couple of small scramjet engines mounted on the wing pylons taking fuel from the aircraft fuel system... sort of the opposite of an external fuel tank.

    On an Su-35 you could fit them on the wing tips... but at the end of the day I would think it would be better off with jammer pods on the wing tips instead.

    BTW extra thrust wont help evading AAMs or SAMs... you are much better off with a decent ESM suite and DIRCMs system.

    Point is that a missile who engaged you has a slow turn and a aircraft who use small engines for a sudden turn might get faster in the back of a following missile or a following enemy plane. The missile simply has a design which cant make fast turns.

    Also the small engines mounted near the main engine but in angle would not make wiring andnfueling so complicated because you dont have to put them in wings.

I really hope Mig's 5th gen Mig-29 replacement isn't a single engine plane. If they make a single engine version than it should only be for export, and not for domestic use.

    What little I can find on the LMFS stipulates a single engine. That being said, I would speculate that a 5th generation MiG aircraft would be designed with naval applications in mind - that means dual engines (which are universally prefered for carrier operations - F-35C not withstanding).

    This is just my opinion, but If the 1.44 can serve as any guide, MiG will retain two engines for the Fulcrum replacement.

    It wont be a single engine, VVS has declared that they will only have 2 engine fighters in the future. Likely Fulcrum's replacement will be 2 engines, however don't rule out a single engine version for export. I should also add that single engine is ok for drones.

    This is little off topic Off Topic , but still good option for export. I have in mind, that Russia could very easily modify Yak-130 trainer into very effective single engine light multi-role fighter with placing 1 RD-33MK engine from MiG-29K. This engine is also good for over the sea operations, as this engine is for carrier based fighter. They need to redesign back part to install 1 bigger engine with afterburner and to enlarge the nose to install radar like Zhuk-M or Zhuk-AE.As Russian air force don't need single engine planes, they could make this version of Yakovljev "officially internationally" together with Novorussia and build a production plant to build or just to put together near Lugansk airport and of course in Russia too. This plane could have same carracteristics like South Korean FA-50 or Indian Tejas or Pakistani JF-17. It could be the basis for new Novorussian air force and could be as well very interesting for other ex-Soviet republics and many other states in Asia, Afrika and Latin Amerika as cheap and reliable plane.

    You're basically describing MiG-33.. an old concept from MiG

    True and there was also Sukhoy S-55 project more than 20 years ago. But they were only on paper if those projects ever come that far in development. On the other hand Yak-130 is in full production with all needed tools and systems developed. For Yak-130 it is just another version of plane, which could be quite quickly in production. Other option is to install two engines AI-222 with afterburners and it still need to reshape its rear end for longer engines. In this case we have all components already developed. Just to put them together in plane and test it.

    Forget hollywood BS... missiles have flight speeds comparable to rifle bullets and zip past their targets often quicker than an eye could follow... and they don't come around for another go at the target or fly with the plane like two planes in a dogfight.

    Even if the missile could do a 180 after missing its target what is to stop it detecting and locking on to the aircraft that launched it and scoring an own goal?

    Also the small engines mounted near the main engine but in angle would not make wiring andnfueling so complicated because you dont have to put them in wings.

    Small engine wont offer much extra thrust... and would need full electronic management systems and fuel lines to get fuel to them. At the end of the day it would be much easier to add extra fuel in the main engines exhaust and increase the thrust of the AB.
