On the way to the electric aircraft: a new development on the MAKS-2017

According to the blog bmpd, SIC “Institute named after N.E. Zhukovsky ”and associated scientific organizations presented to the public at MAKS-2017 a mock-up demonstrator of a hybrid electric power plant.

Its development has a promising nature and is carried out as part of the creation of an all-electric aircraft. The specificity of the product consists in the use of electrical equipment (electric motor, generator, tires, etc.) using the effect of high-temperature superconductivity.

The power of the electric motor in the presented equipment is produced from batteries and / or from a generator, driven in rotation from the shaft of the gas turbine engine. It is intended to achieve rated power in 500 kW.

This power plant is an intermediate step, as the ultimate goal is the creation of a fully electric unit. Equipping the aircraft with it will reduce fuel costs, the emission of harmful substances, reduce noise and increase the resource of the gas turbine part.

CIAM, SibNIA, TsAGI and CJSC SuperOks take part in the works. The coordinator is the Research Center “Institute named after N.E. Zhukovsky. It is expected that at the first stage a hybrid-electric power plant based on superconductors will be developed. After that, it is planned to proceed to the creation of a production electric motor for an aircraft designed for 9 - 19 passengers. Total implementation of the program should take 3 year.

The development of this power plant is an important practical step of Russia towards the creation of a fully electric aircraft. We are convinced of the need to form a systemic scientific and technical reserve in this area. These are technologies that will ensure domestic competitiveness aviation technicians in 15 - 20 years in a new technological order. According to our estimates, new energy sources on board are one of those areas where breakthrough results can be achieved.

- explains the general director of the Research Center "Institute named after N.E. Zhukovsky "Andrei Dutov.


According to the head of CIAM, Mikhail Gordin, work in this direction has been going on all over the world, at CIAM, in particular, for more than 10 years.

Electrification is considered as the most promising technology in the aircraft industry. And the key place here is precisely the power plant. Today, the interests of our scientists are focused on the creation and testing of elements of hybrid power plants, fuel cells with high specific indicators and energy storage devices.

you don’t even have to read the exact same canoe as with all hybrids, you need to be careful to use the internal combustion engine + generator first to lose efficiency on the movement of the pistons, then on the generation of current and finally on the inverse conversion to rotation. If in belaz, ships and diesel locomotives this is justified due to the high mass of the car with the load, then in cars and tanks this is not necessary.

It seems strange to me that these are all hybrid developers who are fixated on this engine, it is high time to get rid of it ...

According to the concept by which modern e-mails are built motors it is impossible to avoid the parasitic effects of self-inductance in the coils of the windings. Therefore, the question rests on the fact that the basis must be changed in these e-mails. engines so that they can be used simultaneously in one device on different planes on the one side of the engine and on the other generator. Then the battery only initiates the start-up process, and the rest of the process is consistent with the necessary parameter of the generated energy on the generator and used on the engine. But the most important thing is that a propulsor is included in this interconnection system, which also works as a generator. With all this, again it is worth returning to the fact that it is necessary to get rid of parasitic physical effects that grow equivalent to the growth of both the generated and consumed energy, which greatly affects the failure of the entire email. equipment. From the foregoing, the conclusion is simple, it is necessary to use a fundamentally new type of induction devices. You definitely can’t call them coils.

[drunkram]

We do not stand still, many companies are working on it both here and abroad, both military and civilian, it is only a matter of time before such systems become effective enough for use in aviation.

[gridasov]

There is no doubt that I work in this. But the basis for a breakthrough, which means creating a reliable and highly efficient process. which would ensure a safe and economical flight of any scale aircraft, obviously not. Therefore, I understand everything and ask the question, "what should be the basis for such a breakthrough." Correctly such a basis can only be the creation of a fundamentally new element base of devices representing both inductive and storage and distribution e-mails. magnetic processes. And those who will give out such breakthrough ideas and begin to master them first will be in the leaders of development for years and years to come. , and this is politics and weapons, prestige and real achievements in science and technology.

[RED PARTISAN]

Not in aviation. What is the point of using a gas turbine engine to rotate the generator so that it generates energy to rotate the electric motor, if the gas turbine engine independently provides traction? The efficiency of such a power plant will be lower than that of a simple jet engine. This means that a larger turbine will be needed to compensate for conversion losses. Or all the hope for capacious batteries? The power of aircraft engines is huge, so the mass of the buffer of the most advanced batteries will be measured in tens of tons. A plane is not a ship or a bus to shove a dead load of such mass into it.

[gridasov]

Uh no.! Propeller blades are induction elements el. magnetic system, and the removal of the potential difference occurs on the periphery of the housing as a stator. This creates an alternating magnetic field. The blades create EMF, and it can be significantly strengthened. The cradle has reached an influx on the shoulder blade, and for example, we have a full justification of the extent to which this can be used and why. And the blades in the hydro-gas-dynamic flow strengthen EMF even more. Everything is very simple, optimal, but cardinally more effective.

And you did not think that recently defense projects have come up that require a powerful but compact source of electrical energy, and the source itself is not voiced. (with the exception of atomic batteries, according to which they seem to have begun working on the working substance). Maybe they solved the problem with the source, well, or on the way to the solution, and we are on the verge of a revolution :)

[gridasov]

Do not believe in fairy tales. The fact is that it is impossible to create a more or less high-potential source of accumulated charge, so the main thing is to hold it. He is sure to "break through" to Earth. Therefore, the problem is the creation of such a device in which it is possible to hold a charge of high density with non-insulating protection elements. but in a completely unusual way. But for this it is necessary to understand the basic principles of the distribution of magnetic force flows, and not abstract email. Magnetic field. So there is no knowledge and there will not be and cannot be a spontaneous invention.

[RED PARTISAN]

There is only one compact source of energy - a tank with fuel. The specific energy consumption of the best batteries and fuel cells is several times inferior to conventional gasoline.

[gridasov]

I repeat that even highly enriched material cannot produce a high energy density of magnetic fluxes. Yes, in the long-term process of using low potential, this can have an effect. but the problem lies in the fact that it is necessary to create a high-potential from a low-potential magnetic flux, and this is a technology and special ones according to the principle of operation of the device. Another thing is that, for example, in our reactor, the radial radiation of radioactive material can be converted into linear and concentrated, yes! And in or nuclear engines and batteries of radioactive materials, this is an unjustified occupation - at least in the way they are going to use it.

Some kind of sign you have is strange. According to your nameplate, acid batteries have a specific (peak) power of up to 10 kW / kg. I believe that this graph is related to the frequency regulation in the network (since there are both flywheels and capacitors).
What is unknown vertically (presumably specific energy stored).
Talking about spin solid state batteries is still too early.
The HTSC-based generator should be driven by some existing engine (if it is an aircraft, then a thermal (turbine)).
There are no obvious breakthroughs in energy storage, except for the creation of lithium-ion batteries and fuel cells. But the road will be overpowered by the going one. Until recently, electric planes were fantastic, but today they (both battery and fuel cells) can already be really used as training.

The basis of the technology is HTSC wires, which, like other superconducting materials, do not have electrical resistance. The use of such a wire makes it possible to achieve a very high current density when using cables of a relatively small cross section.
The main distribution was gained by two high-temperature superconductors - YBa2Cu3O7-x (YBCO, Y123) and Bi2Sr2Ca2Cu3O10 + x (BSCCO, Bi-2223). Materials similar to YBCO are also used in which yttrium is replaced by another rare-earth element, for example gadolinium, their common designation is ReBCO.
Produced by YBCO, and other ReBCOs, have a critical temperature of 90-95 K. Manufactured by BSCCO reach a critical temperature of 108 K.

And whether it drank.

This is an attempt to catch up (regular)

Modern HTS tapes have a current-carrying capacity in 200-300 times as large as those for traditional conductors - copper and aluminum.

A unique property of the material is the absence of electrical resistance at a temperature of 77 K and a high current density, which, together, allows you to transmit much more power.

who is she, air?
potential energy is roughly a function of the arrangement of bodies. That is - they raised the brick a kilometer above the ground - gave it potential energy.
but how to "extract" this energy, that’s the question ..
if you drop a brick from there, the potential energy will go into kinetic
can be used for military purposes

[gridasov]

Everything is a little different. In order for a raised brick to a certain height to do useful work, it is necessary to expend energy on lifting it. But in the environment of hydro-gas-dynamic space, there is such a parameter that the pressure vector of this space is always in the center, i.e. this is a universal deception. that air is crushed by a pillar or water in Mariana or where a hollow is capable of crushing everything and everyone and making space lifeless. Air and Water have their own molecular force, which forms these spaces, which means pressure is always inward. In general, this is simple. without taking into account the centrifugal forces of rotation of the Earth, without gravitational forces at its center of mass, etc. Therefore, the medium is elastic and air and water, and therefore, with an increase in the speed of movement in these media, the object of movement collides with elastic resistance. And this vector can be used to level this resistance. Moreover, the process can be dramatically activated by the fact that the atomic-molecular bonds of air and water as substances can be turned into an even higher potential of this elastic resistance. Which ultimately transforms into a kinetic energy vector of the stream discarded as reactive force. By the way, Tesla spoke about such processes, but the methodology. it is not surprisingly developed only now and only by us
