Russian electric aircraft engine will be tested in flight

Russian electric aircraft engine, developed by specialists from the Central Institute of Aviation Motors P.I. Baranova, will undergo flight tests this year. The upcoming plans on the eve were told by TsIAM General Director Mikhail Gordin.

According to the functionary, the unit will be tested using the Sigma-4 apparatus. The latter is a two-seat light aircraft with a take-off mass of 600 kg, developed by TsIAM together with the IPCP RAS.

This year, the car flies on batteries, and next year it is planned to conduct tests using solid polymer fuel cells, which will increase flight time.

It is worth noting that the prototype of the first Russian electric motor for aviation was ready last year. However, the previous experiment failed: a 60-kilowatt (80 hp) electric motor could not lift the plane into the air.

According to Gordin, this time the experts took into account all the shortcomings of the system, which were corrected in the current version of the invention.

Recall that in addition to the aforementioned unit, the Central Institute of Aviation Motors. P.I. Baranov is working on a 500-kilowatt demonstrator of a hybrid power plant. The latter is planned to be tested at the Yak-40 flying laboratory, presumably in 2 years.

    The transition to electric movement leads to a problem in the form of electric motor operation on a screw. For an electric motor, this is a fan load at which the required power has a cubic dependence on the rotation frequency (P ~ ω3). Pumping power through the engine is associated with losses, including losses in copper, i.e. heat losses also increase in the same way. There is a problem with heat dissipation, the dimensions grow, the magnetic properties of the magnets fall, if they are on the rotor.
    Existing approaches to solving this problem, including the use of superconductors, can be described as a “solution to the forehead,” which are also not without drawbacks.
    However, a radical solution to this problem can be achieved only by abandoning the traditional approach to constructing an electric motor-screw system, but this is already a different technological level, a new generation of electric motors. To confirm or refute this, experimental research is needed, as they say, the devil in detail. So the thing is small - to begin.

    I remember a year ago they boasted wunderwafers on superconductivity.
    1) Is that she ???
    2) There was no news that I could not fly ...
    3) Are they randomly poking? It seems that in the aircraft industry it is possible, if not calculated, then conduct analog tests .....
