PD-8 engine for SSJ-NEW aircraft will receive a new gas generator

In Russia, work continues on updating the fleet of gas turbine power plants of a new generation and class for the domestic short-haul passenger airliner SSJ-NEW. According to the press service of the United Engine Corporation, the company's team has assembled the first experimental gas generator for the promising PD-8 engine.

According to UEC representatives, if the design and development of a new generation power plant is successfully completed, it will be possible to equip not only SSJ-NEW with it, but also other aircraft of the same class.



Now, after the working prototype is ready, it will face the stage of critical bench tests to confirm the main parameters and characteristics declared by the engineers. A working sample will also be on display at the annual specialized exhibition of achievements aviation industry MAKS-2021, which will be held in July in the city of Zhukovsky near Moscow.

According to the manufacturer, during the design and experimental production work on the PD-8 engine, an assembly infrastructure was developed and manufactured, sensors were installed to monitor the condition of the product during testing, and the rotor of the new gas generator was assembled and balanced directly. The subject of observation will be the mechanisms for debugging the automation of control and control of the launch of the power plant.

The "heart" of the new PD-8 power plant, which is an important detail - the gas generator, has been assembled. Now the next step is testing and the most crucial moment - the first physical launch, then a public demonstration of what has been achieved

- said the deputy general director of the State Corporation "Rostec", which includes the UEC, Vladimir Artyakov.

The successful development of the new PD-8 unit was facilitated by the extensive experience of engine builders who worked on the “elder brother” of this power plant, the PD-14 engine, which is already intended for the domestic medium-haul MS-21 airliners.

The creators and developers have no doubt that the tests will fully confirm the characteristics and innovative solutions they have put into the product. One can be sure of this, if only because the project to create PD-8 (as well as other promising Russian engines) is being carried out in broad cooperation of UEC enterprises, as well as companies belonging to the Rostec holding.

        a set of obscure overseas letters.

        It was conceived on the basis of broad cooperation with Western countries (electronics, hydraulics, engines, etc.) - it turned out to be unreliable. And the name "Dry Super Jet" was invented for this. And they pushed it into the foreign market, and they got burned: you need to have maintenance points, spare parts warehouses in the countries where it is operated (or nearby) - this was not the case. But in principle, I think we need to focus on providing domestic aircraft its civil aviation, through leasing, government procurement, and so on - an unplowed field for work on replacing Boeing, Airbus and other Embayers.

                direct mode is essentially a control of the Tu 154 and old Boeing. It's just that pilots get used to the fact that the electronics itself sets the angles, pitch, does not allow the plane to fall into critical angles of attack, hit the runway with its tail during takeoff, and so on. And when it comes time to drive in the old fashioned way, the pilots are not ready for this. Although a Boeing pilot who has never flown a superjet has easily coped with it.

                      A delusional video discredits you. The conversation between the commander and the co-pilot is presented as a musical show with someone else's sound.

                      The Il-62 is an airplane where athletic strong pilots have always been taken, since sometimes four of us had to pull the controls (there are no hydraulic boosters) - and the teamwork was the most streamlined there.

      PD-8 is planned to be ready in 2023, the cold section will be from SaM-146, the gas generator has already been assembled. This is not the only good news.

      ... UEC-Perm Motors and UEC-Aviadvigatel have planned to test the PD-2021 engine gas generator in September 35, according to the Telegram channel of the MAKS air show with reference to Alexander Inozemtsev, Managing Director - General Designer of UEC-Aviadvigatel JSC.

      “This year we will assemble and test the PD-35 gas generator in September. This is the "heart" of the engine, it is 70% of the technical and technological problems that can be detected during testing, ”he said.


      ... During this year, UEC will also test other PD-35 engine parts made of domestic composites, including a fan blade made of polymer composite materials, which will be manufactured using two different methods - using prepreg technology and 3D weaving technology.

      In 2022, the first samples of fan rotor blades should be obtained, which can subsequently be used not only on PD-35, but also on an updated version of the PD-14 engine, as well as in the interests of third-party customers.

      In the future, on the basis of PD-35, it is planned to create a family of aircraft engines of various thrust up to 50 tons. The start of ground tests of the engine is scheduled for mid-2023. The start of flight tests at the flying laboratory is scheduled for 2025. The type certificate for PD-35 is planned to be obtained in 2027.

          According to him, the development of a gas generator for PD-8 is planned to be completed next year, and the new turbojet engine will be certified in 2023.

          Enough funds have been allocated for the project, Artyakov noted. "The volume of investments is sufficient to ensure that all work on the creation of a new engine is carried out efficiently and on time," the top manager emphasized.

          CR929.
          TsAGI has studied the basic aerodynamic model of the joint Russian-Chinese SHFDMS CR929 with a sickle wing tip - cyberlets. The purpose of the next completed phase of testing was to determine the influence of deflection of controls and cruising aerodynamic characteristics of a wing with a very large narrowing, as TsAGI explained - "a record for domestic civil aircraft."


          Earlier, in the T-128 transonic wind tunnel of TsAGI, experimental studies of the thematic model CR929 with two wing options were carried out, and in December 2019, the purges of the High speed standard model (HSM) were performed, made at a scale of 1:39 in the fuselage plus configuration. wing.

          https://aviation21.ru/v-cagi-vypolnili-produvki-kryla-cr929-s-sajberletami/


          ... Construction of the first Russian-Chinese long-haul wide-body liner CR929 should begin this year. This was reported on January 23 by Yicai Global, quoting Yang Zhigang, chief engineer for preliminary research of COMAC.


          According to him, the launch of production means confirmation of the shape of the aircraft, its dimensions, the final selection of the main structural materials, approval of the main suppliers of systems and assemblies.


          “If this is possible, then we definitely hope that some of the main systems will have two or more suppliers,” said Yang Zhigang. He believes that this approach will provide an insurance mechanism for the creation of the liner.



          CR929 is being developed by the CRAIC joint venture, created in May 2017 by COMAC and the United Aircraft Corporation. The headquarters of the enterprise is located in Shanghai, where the serial production of the CR929 will also be organized. The base model CR929-600, with a capacity of 280 passengers, is comparable to the Boeing 787 and has a flight range of at least 12 kilometers.

          The publication writes that CR929 will be focused on China, Russia and the CIS countries as the main sales market, the Asia-Pacific region - a secondary one.

          Yicai Global announces the start of mass production in 2021 of the CR929 liner, however, it is obvious that the publication made a mistake, and if the construction of the first liner begins in Shanghai, it will be an experimental aircraft, which will first undergo factory development tests, and then certification.

          On July 8, 2020, it became known that due to the emerging difficulties in joint work with Chinese developers, the planned start date for serial deliveries of the aircraft is shifted to 2028-2029. Ravil Khakimov, Director General of Irkut Corporation, announced this at a meeting of the Economic Policy Committee of the Federation Council.

            In fact, the question is very controversial. If China and the United States manage not to slip into war, then the Chinese will most likely prefer the American engine. Or English. Or they will make every effort to bungle their own. So the prospects for the PD-35 are not as bright as we would like. In any case, we'll take a look.

    Well, perhaps a new modification of the Il-96-400M for two PD-35s. request No. In general, they first create an engine, and then an airplane for it, and not vice versa. The engine takes longer for the aircraft to be created. There will be an engine, there will be an aircraft, and not vice versa.

    Well, what kind of modification? At the very least, you need to redesign the wing and landing gear. Those. actually design a new aircraft. He falls into the same class with 777. Can he compete? I don’t think so. Perhaps we could even produce several dozen aircraft. And for this you need to design a new aircraft? You can, of course, but stupid. We do not have the capacity to do this - we have much more urgent tasks.
    So it turns out that the prospects for the PD-35 are very vague. All hope is in China.

      Even if the whole airframe .... The cost of the engines and the rest of the configuration is the main cost of the airplane. Remember how the pseudo-liberals screamed about the Superjet.

        What sales prospects will the new aircraft have for the redesign to make sense? At whose expense is the banquet?

          At first glance - you are right - there are no prospects.
          But the world is changing and commercial ties and even war has become possible. Cost-effectiveness is becoming more and more in demand and the sooner you switch the more benefits you will receive.

          Russia participates in a project with the Chinese in CR929 - all aerodynamics and wing design. This experience can simply be taken and used.

            It is clear that I would like my own. But I somehow strongly doubt a domestic aircraft of this size (under the PD-35). Here MS-21 can be very much in demand. So most likely the PD-35 will go either to the CR929 or to a domestic truck (you can make a twin-engine analogue of the C-17).

              Your right to an opinion.
              But for me, several projects will require such an aircraft. For example: an air launch, a platform for a laser anti-satellite system, flying air defense systems (in places of possible massive missile strikes or to support depleted ground systems), an urgent transfer of human resources (civil and military) and cargo ... for rotational work in the north and temporarily developed areas (living there is constantly unprofitable) ...

    SSJ-NEW - what the hell is this? Like Poghosyan sawed the loot and dumped to saw in MAI? There is nothing where the Armenians have visited .... How the locusts will clean everything .... The name of course is "SUPER ..". What is super there? When will they stop bragging and deceiving. As for PD-8, if it will be made for 8 years, then you can immediately bury it.

      This is the same SSJ-100, but assembled from completely domestic components, that is, completely import-substituted.

    It's funny to hear about PD-14, which is supposedly the "big brother". This is PD-8 (Russified SaM146) - de facto, is the older brother for PD-14, judging by the age of the structure

      SaM146 was produced in cooperation, where Russia made the cold part of the engine, and France made the hot one. Now Russia has made itself, without French technologies, its hot part, based on the technologies developed during the creation of a completely domestic PD-14. Therefore, the PD-8's "older brother" is precisely PD-14, on the basis of which the hot part of the PD was developed. -eight. PD-8 is not a Russified SaM8, since the French did not share with us the technologies of the hot part of the engine at the insistence of the United States, since the SaM146 engine uses American technologies, among other things. The hot part was created on the basis of PD-146 technologies.

        HPC PD-8 was designed without the influence of PD-14, the Permians, in many ways, only interfered
