    Interview with Sergei Bogan : With all my deepest respect for the Su-27 I can say that in comparison with the Su-35 - it's like a truck and a car.

    https://www.aviaport.ru/digest/2017/12/06/504985.html
    So does that mean the Su-27 is like an AWD sedan whereas the Su-35S is like a four-wheel drive pickup? That would make the Su-34 the same model pickup only with a bigger motor, longer bed, and a crew cab.

      Well the Su-35S would be the speedy and sexy Turbo model with more power, while the Hellduck has the TRD package for mud moving.

        I think its also related to the more precise and responsive feel on the flightstick due to new FBW. And TVC integral.
        Bodgan has mention this before.
        Anyway my point was its not only about more thrust.
        Thanks

          "MiG" diversifies the product line and is working on a combat aircraft of the sixth generation

          http://www.nationaldefense.ru/includ...9/detail.shtml

          Deliveries to the Russian airlines of the regional passenger turboprop Il-114-300, which are scheduled to start in 2022, will save "about $ 5 billion that would have been spent to buy similar equipment from our foreign competitors," said recently at a meeting on development Civil Aviation President of the UAC Yuri Slyusar.

            Good thing is Mig is diversifying into civilian program in Military one they do not have any new product except for Mig-35/29K.

            Future assured program appears to be UAV/UCAV but that would be a small percentage of what Mig used to be , If PAK-DP gets approved in GPV 2018 then they would have something major to work on military side , Else Civilian Program , Upgrades of existing Mig aircraft and UAV/UCAV for Russian Armed forces would be their future for a design bureau that dominate most of SU military program during cold war.

              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.

                Only peripherally related to the RuAF but indeed all about Russian aircraft industry:



                Staying true to their word, the Sukhoi SSJ now gets composite blended winglets (they call them "saber wingtips"). It was first reported two years ago, and SSJ International said they'd be ready for flight by the end of 2017. CityJet/Brussels Airlines is supposed to be the launch customer.

                    The demise of Mig seems to be a trendy topic lately. Anything that survived the 90's or was worth reviving after the 90's , is probably here to stay. There are 26 countries with Mig 29's in service. Brand new replacement Mig 35's would be perfect for these countries. They wont have to change a thing. Just plug and play.

                    It blows my mind that Sukhoi is not building a supersonic airliner. It would be the perfect niche market to keep them busy

                      Those 26 countries won't be replacing mig-29 with another variant few would most won't , reason is twin engine fighter are expensive to maintain , mig should have ventured into single engine affordable fighter which can do what 80% of mig-35 can do but would be low on maintenance and life cycle cost export wise that stands a better chance to succeed

                        ^ I'm not saying all will. We wont know that. But its a fair amount of countries that are operating 2 engines right now.

                          Staying true to their word, the Sukhoi SSJ now gets composite blended winglets (they call them "saber wingtips").

                          This jet, seems to have a different kind of winglets;

                            That's a Tupolev. They started using winglets back in the late 80's/early 90's already, on the Tu-204/214. Same with Ilyushin, they put winglets on their Il-96 way back in the late 80's. In fact, they were pretty early in the world with that. But in both of those cases, they're classical canted winglets, not the more high-tech blended kind.

                            The SSJ and the MS-21 both lack winglets despite being far newer designs, but it's a conscious choice I reckon. The SSJ is short-medium ranged and mostly just dashes between cities spending very little time at typical airliner cruising altitude, so winglets add a lot of complexity and weight without providing that many benefits there. Now, they're serious about the longer ranged version though, and winglets now make more sense. It's also valuable from a marketing perspective really, as winglets are automatically associated with modern airliners.

                            I suspect the MS-21 will also receive them eventually, at least the longer versions, but they're as of yet only at the project stage.

                              The Tu-204 winglet is actually pretty close to a blended one.

                                Both Tu-204 and IL-96 were designed to be among the top, but the events of the early 90s and more so the oligarchy regime in Russia made sure these aircrafts were not supported. They instead went for Boeings and airbuses and probably collected sacks in commission.

                                Couple of magazine articles/interview that mentioned Tu-204.

                                    The new Russian long-range interceptor MiG-41 will become the fastest fighter in the world, it will be able to deal with hypersonic missiles.

                                    This was reported to Interfaxon Wednesday the chairman of the Federation Council Committee on Defense and Security Viktor Bondarev. "The MiG-41 is under development. It is premature to talk about his arrival in the army, but most likely it will not be until 2025, "- said V. Bondarev, until recently - the commander-in-chief of the Air and Space Forces of the Russian Federation. The MiG-41 (long-range intercepted long-range aviation complex, PAC DP) should replace the interceptor MiG-31. "It is supposed that this will be the fastest fighter in the world, the most inconspicuous for radars. The range will be in the range of 700 to 1500 kilometers. It is planned to equip it with an R-37 air-to-air missile, as well as radically new missiles, "Bondarev said.

                                    According to him, research and development work is carried out within the framework of the PAK DP project. "It will be a super-modern heavy interceptor fighter that will be able to withstand not only standard low-maneuver threats like cruise missiles, bombers, including drones, but also threats from hypersonic missiles," Bondarev said. "The MiG-31 proved itself well, but it was released in the late 1970s and is now outdated. Its service life expires in 2028. He perfectly fights with strategic bombers, supersonic reconnaissance planes and cruise missiles. A unique combat aircraft, there are no analogues in the world. But, unfortunately, such new challenges as hypersound are not available for him. And to effectively combat highly maneuverable targets, the 31st sample is not intended, "Bondarev said. "Russia will have a super-modern fighter-interceptor before the expiration of the MiG-31 service," he said. On December 13, General Designer and Vice President for Innovation of the United Aircraft Corporation Sergei Korotkov told Interfax that the work on the creation of the PAK DP could start as early as next year.

                                    "Most likely, in 2018, work will begin. I hope so. Everything depends on the output of the main document - the state armament program, "S.Korotkov said. According to him, at the moment there is a process of discussing the technical assignment for the aircraft between the developer (RAC "MiG") and the Ministry of Defense of the Russian Federation. "The main thing is that the requirements (of the customer - IF) correspond to the amount of financing," the general designer emphasized. He did not rule out that the new interceptor could perform tasks in space. "They will say" into space "- we'll do it" into space, "Korotkov said. MiG-31 is a two-seat supersonic all-weather long-range interceptor. It is capable of speeding over 2 Mach (sound speed) and is designed to intercept and destroy air targets at extremely small, small, medium and high altitudes, in simple and difficult weather conditions.

                                    In July 2017, the general director of RSK MiG, Ilya Tarasenko, told reporters that the company is developing the PAK DP initiative, but soon expects to sign a contract with the Russian Defense Ministry for research and development (R & D).

                                        Has anyone came across the full presentation video of CR929?
                                        This is very good promotional video of the new wide-bodied aircraft which is now a joint Russia-China project.

                                          Will India buy a Russian aircraft with heavy Chinese input?
