A flying laboratory with an electric power plant is being created in Russia

76

ZAO SuperOx has developed the world's first engine with an efficiency of 99,7 percent, the principle of which is based on superconductivity. Now in Russia they are creating a flying laboratory with an electric power plant, where such an engine will be used.


It is reported by the news agency. Interfax.

Andrei Dutov, Director General of the Zhukovsky Institute, told reporters today that, in his opinion, the serial production of aircraft with fully electric power plants will be launched by 2030.

Now the Siberian Research Institute, which is part of the Zhukovsky Research Center, has created the first flying laboratory on an electric drive, which will make its first flight this year. It is built on the basis of the Yak-40 aircraft, in the nose of which, where the propeller is located, an auxiliary 500 kW electric motor is installed. The standard engine in the tail section was replaced by a turboshaft gas turbine engine with an electric generator.

Today the laboratory in Novosibirsk has successfully passed ground tests. The aircraft was rolled out of the hangar, after checking the compatibility and stability of its systems.

In two years, a similar flying laboratory is planned to be created on the basis of the Il-114. An electric motor with a capacity of 1 MW will be installed there.

      Yes, the text of the news is somewhat damp. Or the journalist misunderstood and altered.
      Although there are such Yak-40 laboratories for engines with a nose rotor (engine)

        Novosibirsk. February 5th. INTERFAX-SIBERIA - A production aircraft with a fully electric power plant may appear by 2030, says Andrei Dutov, Director General of the Research Center "Zhuklovsky Institute".
        "According to all world plans, such aircraft should appear somewhere around 2030," he told reporters in Novosibirsk on Friday.
        He noted that the electric motor developed by SuperOx CJSC using the effect of superconductivity is the first in the world.
        According to him, a flying laboratory with a hybrid power plant has been created at SibNIA. based on the Yak-40, a 500 kW electric motor is installed on it as an auxiliary one, the plane should fly in 2021. The electric motor is installed in the nose of the aircraft with a propeller, In the aft fuselage, the standard engine was replaced with a turboshaft gas turbine engine with an electric generator.
        The next flying laboratory based on the Il-114 will appear in two years, a 1 MW engine must be created for it, he said.
        "The next laboratory will be created in two years, it will fly on electric motors, without auxiliary electric motors," Dutov said.
        He also noted that similar engines can be used in shipbuilding and rail transport.
        According to Andrey Vavilov, Chairman of the Board of Directors of ZAO SuperOx, the efficiency of the electric motor is 99,7%.
        The scheme will be adapted for the IL-114 flying laboratory, he said.
        Andrey Grigoriev, head of the Advanced Research Foundation, noted that certification of the aircraft electric motor is expected to be completed by the end of the 2020s.
        “According to our plans, the plans of the Ministry of Industry and the Zhukovsky Research Center, certification, as I understand it, should be completed, everything should be done by 2030 so that electric planes appear in life,” Grigoriev said.
        On Friday, in Novosibirsk, the ground testing stage of the flying laboratory on the basis of the Yak-40 aircraft began, the aircraft was rolled out, the compatibility and stability of the work was checked.
        "Everything is working normally," Vladimir Barsuk, general director of the Siberian Research Institute of Aviation, told reporters.

            The helicopter transmission can already be replaced. The specific power of the generator - engine reached the level of the gas turbine.
            And even in the Mi-8MT and Mi-24 the gearbox weighs 2 times !!!! more than two engines. (two TV3-117 engines of 295 kg And the main gearbox BP14 or BP 24 - 820 kg or 830 kg. Plus the transmission in the tail).

            Of course, the price ... Of course, the very beginning of the road ... But the light is really visible.

      The flying laboratory based on the Yak-40 aircraft was developed by the FSUE SibNIA im. S.A. Chaplygin ". For testing an electric motor with a propeller was installed in the nose of the aircraft. A turboshaft gas turbine engine with an electric generator is installed in the rear fuselage instead of the standard AI-25 engine. In the central part of the fuselage, lithium-ion batteries were installed, which are also part of the GSU.

      The decision to use the Yak-40 aircraft was made in 2018. In the same year, an aerodynamic model of a flying laboratory in a wind tunnel was created and tested. To equip the Yak-40 with an electric motor, it was remotorized (two of the three main engines were replaced with modern ones with a higher thrust), the airframe design was improved, parts and assembly units were produced, with the help of which the demonstrator is installed on board the flying laboratory.

        To test the operation of the generator-motor circuit. It doesn't even matter what the plane will be, but the Yak-40 is better suited, because it has 3 engines and can be tested more or less safely by installing an electric generator instead of the standard engine.
        And the scheme is interesting for helicopters, vertical takeoff planes and much more.

    The place of these aviation charlatans in the felling. The electrical efficiency of the gas turbine engine used to drive the generator is at best 20% (taking into account the compression losses, mechanical losses on the generator shaft), compared to the direct drive to the propeller. To this must be added the increased weight at the expense of electrical machines (generator and electric motor, wires, control system) .In the USSR, for such arts initiators would definitely not get a job except as a watchman ...

        It's scary to take you as a watchman ... do you know anything about the law of conservation of energy? Air is a worthless conductor in general. Most of the energy will simply dissipate in the atmosphere. Therefore, the wires are copper, high density and therefore conductivity :). Who teaches you at all .

And you, besides copper wires, do not know anything about the transmission of electrical energy. The world has been working on the problem of wireless transmission for a long time (since the time of N. Tesla) and there are significant successes in this area. However, it is useless to explain anything to you. You can only bark "like a dog"

    SibNIIA are not lazy at all.
    By the way, they have the option of modernizing the Yak40 as such. With minimal alteration of the airframe's aerodynamics, it is proposed to make it of plastic (composite, of course).
    Just like they remade An2.
    True, both aircraft are with imported engines, they are not of their own.
    Therefore, there are no real prospects.
    Look, they even tried to introduce the same An into the series, they loudly told on TV how it would be beautiful, the plant was even appointed, and then they quietly hung up and a new ROC with a more realistic design. For a piece toy (a technology demonstrator, of course) is one thing, and a Russian factory is quite another.

      So what, a turboshaft gas turbine engine cannot directly rotate the propeller?
      Of course it can, but in this case it is used as a generator. And then I think they will shove batteries into the salon, or tinker with which thread a mini-reactor.

        I understand that it can. I just don’t understand, because I don’t know why a short chain - engine-propeller, replace with a long chain - engine-generator-electric motor-propeller?
        Probably something I don't know.

          They want to determine "Can an airplane fly on an electric engine in principle, the issue of energy supply is put on the back burner. For this, they use the principles of superconductivity, something like that."

          There may also be such an option as placing the generator set in a place more convenient for generating energy, like on diesel locomotives and ships, with such an electric motor efficiency it makes sense, well, perhaps the generator sets themselves can be made from cheaper materials, if they are not placed on the wings eg. hi

      The gas turbine engine (GTE) can of course also directly rotate the propeller. But sometimes a powerful source of electricity is required on board to power, for example, a power microwave phased array antenna or an optical laser .. And if the gas turbine engine will directly rotate the propeller, who then will power the said electrical loads? The second advantage of the aircraft's hybrid propulsion system is that the electric motor can operate as a recuperator of the aircraft's kinetic and potential energy into chemical energy stored in the onboard storage batteries, and thus save fuel. In addition, the mode of operation of the gas turbine engine for the electric generator will be basic, without sudden increases in load, which have a detrimental effect on the resource of the gas turbine engine. frequent shutdowns of the turbine lead to its rapid wear and tear.

      You do not understand, no one will give money for an ordinary theater of operations, the topic is being sawed by more serious guys from Moscow time. And they give for a breakthrough project for the electrification of aviation.

    "....Andrey Dutov, General Director of the Zhukovsky Institute, told reporters today that, in his opinion, the serial production of aircraft with fully electric propulsion systems will be deployed by 2030..... "
    =======
    I did not quite understand: and WHERE do electric motors take energy from batteries (? belay ) or still from a turbine generator, as in a flying laboratory? If it is the latter, then the question is HOW can such an installation be called "fully electric"?
    In general, this is a serious step forward! Efficiency 99,7% - this is serious!

      This is not about the entire power plant, but only about the email. engine.
      = ZAO SuperOx has developed the world's first engine with an efficiency of 99,7 percent, the principle of which is based on superconductivity. Now in Russia they are creating a flying laboratory with an electric power plant, where such an engine will be used. =
      And the efficiency of the entire power plant will be much lower.

        Naturally! Turbines have a relatively low efficiency of 40-45%, for electric motors it is much higher - for low-power ones 70-90%, for powerful ones (over 100 kW) - up to 97%. It used to be considered the limit..... But 99.7% is already seriously! Only some 2-3 percent, but the trick is that it used to be considered practically impossible!!!

    The place of these aviation charlatans in the felling. The electrical efficiency of the gas turbine engine used to drive the generator is at best 20% (taking into account the compression losses, mechanical losses on the generator shaft), compared to the direct drive to the propeller. Added to this is the increased weight due to electrical machines (generator and electric motor, wires, control system)

    You're almost right.
    This is a flying laboratory. And it is not the entire plane that is being worked out, but only the electric motor.
    From what it will be powered in this case, it does not matter at all, even from a steam engine.
    And then the finished engine can be powered at least from a diesel generator, even from batteries, even from solar panels or electrochemical (fuel) cells.
    And a scheme with taking power to the generator from the shaft of a turbojet engine also takes place.

    Colleagues, it seems to me that we have gone a little to the side. I am a person far from aviation, but let me have my 5 kopecks.
    There are advantages even in this combination of GTE-generator-electric motor.
    1. The GTE operates in the optimal mode, providing maximum efficiency regardless of the flight mode.
    2. As you know, gas turbine engines are quite inert, and it takes some time to change the thrust regime. An electric engine is capable of building up shaft power very quickly - even in comparison with piston engines, and this is flight safety.
    3. Non-productive losses associated with the need to maintain 100% power on the generator shaft can be compensated for with the help of a buffer accumulator, where the "excess" power will be merged, and from where the lack of power will be compensated for when operating at overmodes.

        Are you talking about the possibility of replacing the helicopter gearbox, which is three times heavier than the power plant? Or about the successful application of this bundle on the ground, in hybrid vehicles, where it has long been the norm? About unreliability - in your opinion, is the replacement of mechanics and hydraulics in passenger aviation with electric drives also a threefold decrease in reliability?

    The appearance of the Yak-40, with the fourth engine, seems to be sorted out. Now the question is; and whether the diameter of the propeller is not small for such an aircraft. Although there are six blades, the takeoff weight is 13-15 tons. Or is it just to check the functionality of the email. engine under load.
