The engine of progress. What are the features of the Russian power plant PD-14

Exactly a year ago, the domestic airliner MS-21-310 took off from the runway of the Irkutsk aircraft plant. This flight became extremely important for our country, since for the first time Russian PD-14 aircraft engines were installed on the aircraft. Moreover, this power plant can rightfully be called the "engine of progress".

It is worth noting that the decision to create its own engine for the MS-21, which was made by the UEC, seemed to many to be adventurous and impracticable. Indeed, in order for the aircraft to compete on the international market, its power plants should not be inferior to counterparts from the same Boeing and Airbus, which create advanced engines.

Nevertheless, in 2008 the project was launched. Considering that the engine was primarily intended for the MC-21 family of liners, its estimated thrust ranged from 12,5 to 15,5 tons. The base was supposed to be a Prospective engine of 14 tons (hence the name PD-14).

The entire industry was involved in the work on the newest engine. Despite numerous difficulties and skepticism on the part of some experts, our engineers managed to make a real breakthrough. PD-14 became the first engine in the history of modern Russia, which was built from scratch.

But that's not all. The domestic power plant of the fifth generation can be safely placed on a par with the most advanced civil aircraft engines in the world. Moreover, it surpasses its predecessors in terms of specific fuel consumption by 12-16%, and in terms of harmful emissions by about 30%.

An important nuance in the PD-14 design is the presence of serious computers with complex software functionality that controls all processes. In addition, it actively uses new materials and Technology: lighter alloys, high temperature mechanisms, additive technologies, etc.

Finally, the most important thing. It is no coincidence that the PD-14 power plant is called the "engine of progress". After all, it was initially decided that a whole family of units would be created on its basis, ranging from PD-8 with a takeoff thrust of 7,9 tons and ending with a real "giant" PD-35 with a thrust of 33 to 40 tons.

    its peculiarity is that it does not have many competitors, only three countries are capable of producing such aircraft engines, the motor vehicle does not count for it anymore and it did not have such an engine, and since PD14 is cheaper than Western competitors, it turns out that there is no alternative to it in everything world in its class. and MC21 will be cheaper than competitors by 20-30 million, which opens up before him the entire non-Western world, but this is 6-7 billion people

      There will be, if, the whole world, if there will be.

      This is all good. Our people know how to do and can do. Here the question is different, now the West will start hysteria and put a spoke in its wheels. That's what's offensive.

        About PD-14, about PD-35, they have been writing for five years in a victorious spirit.

          About five years this is not enough, because such motors have been developed for decades, and it does not always work out, there are French ones, that on superjets, shit, which we abandoned in favor of the promising PD8, one family with PD-14 and 35. PD-14 already from the 22nd launched into series, for MS-21, by the way ordered for several years before, I mean MS-21.

      That's for sure. We have no competitors in this class. Therefore, they banned the supply of components, thinking to delay us in the development of this engine and the MS-21 for a long time. It didn't work out. And the interest in our development is very large, especially among the Arabs.

    Yes, no one doubted what they would do. They knew how to do isolated things from Ivan the Terrible.
    There are prize-winners of model aircraft, they sculpt such beauty.

    It takes a lot and quickly. Boeing and Aerie churned out 2 planes a day, that is, 4 engines ...
    In general, the Serdyukovs and Rogozins must cope ...

      Chubais or Surkov is preferable.

    I am interested in how much fuel consumption per hour, not by percentage, but by an understandable liter / hour, the English burns as much, the American burns as much, the resource is up to 1 cap of repair, and how much it costs approximately. Then you can try it on with competitors, as well as all the information about previous models.

      This is the biggest mystery. You are not the first to ask this important question. This data is obscured. So there is nothing to brag about.

      Or maybe better how much per pass * km?

    I saw PD-14 back in 2000 - some worn-out year on Perm engines. Rogozin then came and looked.

      If this is really a motor from scratch, launching it in production from 2022 is just fantastic.
      The "hot end" project can then operate in various designs for up to 50 years

    People write correctly. It's not about a piece or even a dozen pieces. And here the problems of serial production can not be solved even in 10-15 years, until everything becomes obsolete. It is necessary to expand how many industries, and where to get so much money, they do not return from offshore companies, and if they return, then it is not to our country. The Central Bank and the Ministry of Finance will not allow investing here, they will scare the GDP with inflation so that the engines will not be needed.

    Saw it this afternoon, MS-21, in the sky. Apparently I went to the landing. The landing glide path is just above us. In the sky, sometimes quite interesting "objects" can be seen.

      Do you live in the second Irkutsk? My son lives there (in Irkutsk-2) and works at this plant as an aircraft designer.

        No, but not far. In Angarsk. Above the industrial zone where I work, they are just finishing the circle and starting to descend. It’s very funny to read the comments of liberals who claim that our aviation industry is dead, all cartoons and propaganda.

          Once he worked in the second Irkutsk, two blocks from the aircraft factory. I've seen enough of aerobatics flights on dryers. It was immediately clear that buyers had arrived at the plant. The Chinese were frequent guests. There, a building was vacated for the MC21 and re-equipped, in which the SU-30 was assembled, and a new building was built for dryers.
