Tests of the improved engine AL-31F M2 for aircraft of the Su-27 family will begin in 2013, reports ITAR-TASS. This was told by the chief designer of the Gas-Turbine Construction and Production Center "Salut" Gennady Skirdov.

According to its nightingales, two engines for flight tests are now at the production stage and should be ready by the end of the year. At the beginning of 2013, it is planned to begin special flight tests (SLI). Negotiations are underway with the Sukhoi holding to test the engine on the Su-34 strike aircraft.

“If we fail to agree on joint testing with Sukhoi, then, as in the case of testing the M1 variant, we will turn to LII named after MM Gromov and continue to conduct them at our own expense,” noted Mr. Skirdov.

The advanced AL-31F M2 engine for aircraft of the Su-27 family was first presented in Zhukovsky at the 2 international forum "Engineering Technologies - 2012". The engine was created as part of the second stage of the modernization of engines of the Al-31F family, which is conducted by the Scientific and Production Center of the Salyut gas turbine building.

The AL-31F M2 has a significantly increased load in all modes, including up to 14300 kgf in a special mode. In addition, the assigned resource has increased significantly, from 2 to 3 thousands of hours.

The new modification introduced a digital automatic control system of the type FADEC specially developed for this engine, which has a full hydromechanical reserve control of the main engine circuit and allows it to be adapted to any “board”, both analog and digital.

The bench tests of the AL-31F M2 engine on the ground and high-altitude in the thermal chamber of the Central Institute of Aviation Motors (CIAM) confirmed the compliance of its characteristics with the stated parameters. Currently undergoing life test engine to confirm the initial resource.

According to the engine developers, the AL-31F M2 has not only increased 1000 kgf, but also lower specific fuel consumption, compared to its predecessor, the AL-31F M1 engine. The low-pressure compressor, the combustion chamber and the high-pressure turbine were refined.

The first stage of the modernization of the engine AL-31F was completed in 2006 year. Engine special mode has been increased to 13500 kgf. The assigned resource is extended to 2 thousands of hours. The AL-31F M1 engine (42 series) is used on Su-27CM and Su-27CM2 aircraft of the Russian Federation Ministry of Defense.

    Remarkably, it will be able to take more payload, maneuverability and so excellent will become even better.

    that is, the bulk of the 27s uses the original engine ...

    This thing is open on the scruff in the photo, is it for maneuverability? Who is fumbling?

      It may be so expressed, but it will be more correct to quickly reduce the translational speed during landing and maneuvering without losing the aerodynamic quality of the aircraft.

      Due to the large area, the brake flap has a large aerodynamic drag and allows you to quickly slow down the plane without reducing engine speed.

      This is if very briefly ..... +! drinks

        And what is the service life of the brake flap, as I understand it, the load will increase on it?

    This is for braking, instead of a parachute. But in part you are right.

    “If we fail to agree on joint testing with Sukhoi, then, as in the case of testing the M1 variant, we will turn to LII named after MM Gromov and continue to conduct them at our own expense,” noted Mr. Skirdov.


    Something Skirdov is modest, he actually can officially apply to the government to allocate funds for testing.
    This is in our Russian interests.

      Not right at the root. The main means of braking on fighter jets. and indeed on airplanes having a landing speed of 320-350 km per hour, this is ... a parachute.

      If it .. didn’t come out .... early release (burned out) ..... cutoff, etc. then on a short strip, and if it is also wet, then 100% .. roll out beyond the limits, and if also with a "smooth wing ... then ATU will not save!"

      Well, he’s not very modest, but he personally turned to the GDP, because Saturn has a lobby in the person of Poghosyan, but here a lot of budget money.

      And Salut’s motor is definitely better .... +!

      Here’s a fact that is little known to the public — a moment little known to the public — Salyut personally demonstrated VVP in the spring (previously there was such an agreement with the Salyut leadership) at the stand his 3rd modification AL-31, with a new 6-stage low-pressure compressor (117-speed on 9 products) and with a thrust of about 15,3-15,4 tons at afterburner and 10 tons at maximum.

      It seems that there is a promise from V.V.P. that the Salyut engine will become the engine of the first stage on the T-50, too. they promised by 2013 to make the final 4th modification of the AL-31 with a thrust increased to 16 tons on afterburner. and non-afterburning traction of about 10,5 tons. - in general, the project is more technologically advanced and closer to the 5th generation than the "product 117" from Saturn, which has powerful patrons like Poghosyan and clearly counts on billions of state money, which, however, did not prevent them from losing the competition on the topic of the 2th generation engine Salyut twice.

      That is, in this case, the 5th generation engine will become a further development and modernization of this engine, which is great because will save money and time.

        I always believed that the AL-31F (AL - A. Lyulka) was the development of NPO Saturn, and the AL-41F developed on its (Al-31F) base was the engine for the MiG 1.44.
        In any case, the news is positive!

      When they do it, why not, because now they put the engines from the Su-50 (Su-27) on the T-35, so when they bring it to the performance characteristics that are in the TTZ ..... unification of all motors for the Sukhoi family is very real. .. drinks

      On the engine of the second stage - the technical task at this stage: 17-18 tons of afterburner traction and 11,5-12,5 tons of maximum!

      This is fairly accurate information!

      This engine is very important for the future aviation of the new generation since it should also become the main one in 2 programs for the 5th generation light single-engine fighter and also for the PAK DA program;

        Is it possible to learn more from now on? Especially in the 5th generation Light Fighter ... it’s very interesting, but the information is zero.

      These should be different modifications with a different control interface (principle). 4th generation - analog control (direct control). 5th generation - digital interface (roughly speaking, a local area network-controlled local area network).

    A good option, but it's time to make new engines, where is 41? Until we catch up with the amers with their 18kgs on the hryaptor, we will lag behind.
