It will come later than the "Westernized" version (first prototype already flying with P&W engines), but it will come. So they won't repeat the same mistake as with the SSJ.

    What if the PD 14 is delayed a lot longer than the actual aircraft?

    I'm sure that in that case Iran will just buy from Airbus and Boeing as they always do so worry not...

    True, but it also costs money and takes time. And bears risk that success is not with the first iteration. Currently Tu-204/214 has all Russian components and MS-21 is likely to have unless somebody took lots of bribes to do otherwise.

    If they want to use them domestically they will need domestic versions...

    SSJ100 will be gradually localized but unlikely 100%.

    I am sure the Russian military can find a use for such an aircraft and they can pay to Russianise it.

    Of course keep in mind the costs to develop Russian equivalents is money spent investing in something that can be applied to Russian aircraft across the board, so not only is it money spent within the Russian economy on a Russian company to allow it to replace foreign companies in the local and international market, it also improves the level Russian companies can work and compete at internationally and domestically.

    One more negative factor is that now US is imposing new sanctions against Iran. This effectively blocks Iranian funds on western accounts. So this 100bln USD unlikely returns home.

    They should withdraw them all immediately... why buy products from such a criminal organisation?

    I can only think Stockholm syndrome.

    Why not do both by selling the western equipped Russian aircraft to Iran right now and using the immediate profits fund R/D for domestic technologies?

    What profits... the western companies making the western components get the most profit from such sales.... it was the same with the Indian Su-30MKIs...

    Thales made out very well on those deals....

    It doesn't seem it will get delayed, it already passed all manufacturer's tests and is now undergoing certification, it is unlikely they will stumble into serious problems at this stage.

    It is going to be very widely used on Russian engines... both new and existing.

    It will be used on new Il-276 (only two per aircraft) and also Il-476 (4 per aircraft).

    An uprated model could even be used on the upgraded and updated Il-106... which might end up being called Il-676 perhaps...

    More amusing is if the US cancels the deal completely and puts Iran under full US sanctions again... that means Airbus but not Boeing...

    Well the fun is that Tu-204 i produced in very slow pace and Iranians unlikely got their orders within 10 yrs or so. With MS-21 can be otherwise though. Thsi complimented with Il-114 can be good solution only if Russian throughput will be increased.

    Money for any investment is in short supply so they have to be prioritized,

    First of all. I do not think they were unconditionally released l otherwise they would be already in Iran. They would be released under condition Iran buys something in US/EU.

    Today, the 145th Sukhoi Superjet made its first flight.

    https://sdelanounas.ru/blogs/100055/

    It is the 27th for this year.

    Also today, an Antonov AN-148 made its first flight at VASO in Voronezh.
    This is the second AN-148 that flew in 2017.
    It is destined for the Russian Defense Ministry.

    They are about to double last year's output with room to spare. 150th SSJ jubilee is also coming soon. thumbsup

    I read in some interview that they do not plan to push production beyond 30 aircraft per year due to market saturation in that segment.

    Even Bobmbardier seem to be exiting civilian segment and only retaining business segment:

    Bombardier screwed up entirely since they were wanting to sell the C400 series to Russia, and Russia planned a huge order (something along like 300 planes) and then Canada had to go all Pro Neo Nazi Ukraine and then sanction Russia. Which really killed the deal and helped nearly bankrupt Bombardier (mixed in with Bombardiers drastic corruption, lack of providing goods on a timely basis or in quality).

    Turkey’s TAI signs civil aviation deal with Russia’s Irkut

    Turkish Aerospace Industries (TAI) has signed a memorandum of understanding (MoU) with Russian company Irkut on a strategic cooperation venture, TAI said on Nov. 13.

    “According to the agreement which was signed, the two companies will implement joint design and production in the field of civil aviation,” it said in a statement.

    The MoU was signed on the sidelines of the Dubai Air Show, which is being held on Nov. 12-16.

    Pursuing a diversification strategy, Irkut Corporation develops and manufactures the МС-21 short/mid-range airliner family for the needs of civil aviation, according to data from the company’s website.

    Meanwhile, for the first time in Dubai, TAI’s T129 ATAK Advanced Attack and Tactical Reconnaissance Helicopter will be showing its performance on the first three days of the exhibition, according to a previous TAI statement.

    Until now, the T129 ATAK has been successfully deployed for several tests and demonstrations in various locations in the world including Turkey, Poland, Pakistan, Germany, Italy, South Africa, Bahrain and the United Kingdom, according to the statement.

    The VIP version of the MS-21 aircraft may appear in 2022


    DUBAI, November 15th. / TASS /. A VIP version of the Russian MS-21 aircraft may appear in 2022, Alexander Rubtsov, president of Sukhoi Civil Aircraft, told reporters on the sidelines of the Dubai Air Show - 2017.
    "The VIP version (MS-21 aircraft) should appear after two to three years of commercial operation, the machine must be cleaned of childhood diseases," he said. "It [the VIP version] is planned unconditionally."
    Currently, the aircraft MS-21-300 is being developed, and at the end of May 2017 it made its first flight. The first deliveries of the aircraft are planned for 2019, the receipt of the type certificate and the start of the batch production - for 2019.

    More than 50% of the aircraft SSJ-100 is planned to be exported

    DUBAI, November 14th. / TASS /. The manufacturer of the Russian SSJ-100 aircraft, Sukhoi Civil Aircraft (SCU), plans to export more than 50% of the aircraft. This was reported to journalists on the sidelines of the Dubai Air Show -2017 by the president of the SCA Alexander Rubtsov.
    He also noted that the share of export sales of aircraft could be 50%.


    "If we say that we are manufacturing and selling 30-35 cars (SSJ-100 per year - TASS comment) - this is a huge volume, almost 40% of the market, we will probably need expansion into the adjacent segments. we consider the development of the car in the direction of reducing the seats, facilitating the airplane to 75-78 and increasing it to 110 seats.In parallel, work will be carried out to improve the design, improve reliability and improve the quality of after-sales service, "Rubtsov said .- According to our forecast, more than half of sales will account for the foreign market in the near future".
    According to Rubtsov, now there are about 120 planes in operation, the 169th copy is going to.
    As previously reported, in 2015 the company produced 19 aircraft, in 2016 - 22 aircraft. This year it is planned to produce at least 30 aircraft

    - Plans are to create a shortened version of the Superjet with 75-78 seating spaces; in accordance to the requirements of a potential customer that's waiting for the new design by Feb. (must be a big customer)
    - Azerbaijan wants to buy a few Superjets in VIP configuration. Definite order for 1 plane, with an option for several more.
    - Unamed Asian country that borders India; preliminary order for 20 Superjets in standard configuration.
    - Africans are looking for replacements for old models, and the head of Sukhoi Civilian Airplanes is hoping to sell some to them.
    - Some interest from European airlines; which makes the current co-operation with their existing customer - Irish CityJet - all the more important. CityJet is in fact pressuring Sukhoi to provide better support and spare parts for the planes; they had a meeting not long ago and a roadplan was agreed upon that Sukhoi is currently carrying out.
    - Interest into the MS-21 airplane at the Dubai airshow was enourmous but no further details on that.

    The UAC estimates its foreign market up to 2035 in more than $ 100 billion - a report
    11/25/2012 9:30:00 AM

    Moscow. November 25. INTERFAX-AVN - The United Aircraft Corporation intends to supply the Russian Defense Ministry with military aircraft worth $ 54 billion by 2035, and abroad - $ 117 billion, the UAC said in a quarterly report.
    "The volume of deliveries of military aircraft manufactured by PJSC UAC up to 2035 in the interests of the Russian Defense Ministry is estimated at $ 54 billion. The volume of the foreign military aircraft market produced by PJSC UAC up to 2035 may reach $ 117 billion," the document says.
    It notes that, as of the third quarter of 2017, the UAC ranks second in the world in terms of the number of military aircraft produced this year, second only to Lockheed Martin Corp. (USA).
    The corporation was informed that by 2035 it plans to produce 2 thousand 450 military aircraft and to increase its share in the affordable market from 20% in 2015 to 40% in 2025 and to 45% by 2035.
    In February, UAC President Yury Slyusar told reporters about plans for deliveries of aircraft produced by the corporation: "The supply plan for the coming years: 152 in 2017; in 2018-1949; in 2019, 203 aircraft," Slyusar said.

    Interview with Head of CIAM: Russia participates in creation of supersonic airplane on hydrogen fuel

    http://tass.ru/opinions/interviews/4809167

    On PD-35 Engine

    -
    Are you working on creating a high-thrust engine (PD-35) for a prospective heavy transport aircraft? When can such an engine be created?

    - The new twin-circuit turbojet engine of large thrust PD-35 is intended for installation on perspective wide-body aircraft, including the Russian-Chinese CR929. It will be much more powerful than the existing D-18T engines for the largest Soviet AN-124 / AN-225 aircraft. Currently, PD-35 is in the stage of research and development (R & D). In the next six years, the necessary scientific and technical reserve will be created for the beginning of experimental design work.

    - What will this engine be?

    - It will actively use composite materials. The efficiency of the engine increases with the increase in the degree of the two-circuit, and in this case the fan acquires ever larger dimensions. And the weight of the fan is up to 15% of the weight of the entire engine. The fan blades PD-35, for example, have a length of about 1.1 m, the diameter of the fan at the inlet is of the order of 3 m. The use of metals in this case leads to an unacceptable increase in mass. It is proposed to produce blades made of polymer composite materials with metal overlays. And each kilogram of saving the mass of the fan leads to a reduction in the mass of the entire engine.

    At the same time PD-35 can not be called the sixth-generation engine. For domestic civil engines, relatively speaking, the fifth generation is just beginning. It is likely to be "5+".

    According to the PD-35 program, firstly R & D is being carried out, 18 technologies are being developed, a demonstrator engine will be created on their basis, then with a small "overlap" in time, OCD will begin.

    The demonstrator PD-35 will include all the key features with the maximum capabilities: fuel efficiency, ease of manufacture, maintenance, etc. Naturally, such a "super-engine" will not go into mass production, as it turns out to be too expensive and unprofitable. When the stage of OCD begins, the tasks of developing its specific characteristics will be set, depending on the specific parameters that will need to be achieved in order for this engine to be in demand.

    Now we are developing technologies and the image of the demonstrator for PD-35. To date, all technical specifications for 18 technologies have been agreed upon, they are formed by both industry and us as the leading scientific organization in the field of aircraft engine building. In the framework of R & D, their detailed development, calculations, modeling is planned, then - the production of a sample.

    Sixth Generation Engine



    - Do you also develop engines for the sixth generation aircraft?


    - It is now considered that "engines" of the fifth generation are coming out and the development of the engines of the sixth generation is being carried out. Experimental design work (ROC) for the sixth generation will probably begin only in about ten years. By the fifth, they are now either being completed or have already been completed. For example, PD-14 is a fifth-generation civil engine - it is now completing the testing and certification process and will begin to be produced serially after a while. CIAM actively participates in its creation: we developed approaches to its design and carried out part of the design work. Now our main contribution is his engineering and certification tests. They take place on our unique experimental basis. All the nodes for the PD-14 were also tested in our country, at the CIAM Research and Test Center, located in the Moscow suburbs. Tests are carried out in high-speed flight conditions, as close as possible to real ones, on special high-altitude stands. In general, all the most complex and energy-intensive types of compulsory tests of aircraft engines are performed in Russia only in the Research Center for CIAM. Moreover, we are testing not only domestic, but also foreign power plants, for example, the French company Safran.

    Among the works in this field conducted by CIAM over the last decade, it is possible to mention tests for certification of modifications of PS-90A and PS-90A1, PS-90A2 and PS-90A3, SaM146, auxiliary power units, as well as certification of foreign power plants for use on Russian planes and helicopters.

    And if we talk about the sixth generation, it is only as a set of technologies, which is necessary to create such engines - that in the West, that in Russia.

    - How long does it take to develop a sixth generation engine?

    - In principle, the division into generations is conditional. Some technologies are already ready, some are in the process of development. Of course, we would like to see as much money as possible in science, so sooner it will be possible to create something new. But the process of cognition is regulated not only by money - it takes time and effort. There is such a thing as the S-curve, which simulates the development of various projects: first there is a rapid development of technology - a sharp jerk up, then comes the plateau - the saturation region. The turbine construction in this curve is now closer to saturation. To increase the efficiency of engines by several percent, you need to invest a lot of time and money. Certainly, there are still reserves for improvement in this area, but every additional percentage of efficiency, each new quality is given hard and expensive.

    At the very beginning of this curve is the electromotive. We believe that in the next few years there will be a rapid growth of technologies related to the electrification of transport, both in the air and on the ground.

    Electric Engine

    "What is an electric motor?"

    "While it's an electric motor and a propeller." In any case, we are talking about screw engines. On the way to creating a fully electric motor, all developed countries are now in the stage of developing a hybrid engine that has both a turbine and a generator that generates electricity. The second option - the failure of the turbine and the preservation of electricity in batteries or fuel cells. This is a longer horizon, because while kerosene is a very effective source of energy in terms of weight. When burning a small amount of kerosene, it gives the amount of energy that no battery can yet provide. But the world is actively developing ever more capacious and light batteries and fuel cells, working, for example, on hydrogen. Work is also carried out on the weight efficiency of the entire engine.

    A separate problem for an electric plane is the amount of energy needed for aircraft needs and the management of its flows. There is a question of managing the outstanding heat, with which you need to do something.

    In general, hybrid and electric traction is a very promising direction, one of the defining technologies for the future of aviation. Now there are many small planes in the world for one or two people, but they all can fly very short. At the stage of the demonstrator of technology and research, the flight hour is excellent, further questions begin. While in the world there is not a single electric plane that could carry passengers or cargo. They fly enthusiast pilots, because the reliability of this technology has not yet been fully resolved. There is still a long way to go.

    - Do you have such demonstrators in Russia?


    - We are working on them. So far, nothing but models, does not fly. A few years ago a fuel cell flew a drone. At present, we have a project to create a demonstrator of a hybrid power plant with an electric motor based on high-temperature superconductivity. There are no similar projects in the world. At the heart of our - a special conductor, cooled by liquid nitrogen, which at a temperature of minus 196 ° C has the effect of zero resistance. As a result, high efficiency is achieved and the mass and dimensions characteristics of the engine are significantly reduced. Two such engines with a capacity of 500 kW each can be equipped with a regional plane for 19 seats. At the level of the demonstrator with the pilot, we can go out in 2019. A manned plane for two places can do at least now. There would be more money, probably,

    Serial gas-turbine engines for aircraft and helicopters of small and regional aviation


    Let's talk about engines for small aircraft. For TVS-2-DT, created by SibNIA to replace An-2, it is planned to install TPE331 of Honeywell. Why do we have no new developments in this segment?


    - The problem is not lack of new developments, they can be. These planes and their engines belong to previous generations. We need large investments in designing, testing and creating production facilities whose profitability is very low. And Western countries, unlike us, have kept their production.

    Recently, a conference was held in CIAM on the topic of creating a single federal concept for the development of engine building for small and regional aviation. A working group was created that will submit proposals to the government.

    Modern domestic serial gas-turbine engines for aircraft and helicopters of small and regional aviation are simply absent today. Currently, only two domestic engines are in development: the TV7-117ST-01 for the Il-114-300 and VK-800S aircraft for the remotorization of the L-410 aircraft.

    Attempts are being made to start serial production of small-size engines (mainly piston engines), since they are also used on unmanned aerial vehicles. However, they need to be developed in a wide range: from 50-60 to 300-500 hp.

    Another important area of ​​research is work on a single-section experimental rotary-piston engine, on the basis of which it is possible to create a model range of aircraft engines with a power from 100 to 400 hp. This is the size of the engine for the Yak-152. But this is a demonstrator of technology. It is necessary to calculate how much the foreign engine will cost, and how much - the domestic one.

    To ensure the competitiveness of domestic small-sized engines, it is necessary to create a scientific and technical base on the technologies of an electric "smart" engine. Studies on these areas are being conducted in CIAM in cooperation with the branch OKB. The implementation of technologies should provide by 2035 a reduction in specific fuel consumption by 15-20%, a reduction in mass to 30% and an increase in reliability and resource by two to three times.

    One of the ways to dramatically improve the characteristics of piston engines is the use of turbocompound circuits in which the energy of exhaust gases is used to obtain the additional power used to drive the propeller or electric generator.
