Russian developers experienced aircraft superconducting electric motor

Then company “Superox” conducted the first tests of electric propulsion system based on the effect of high-temperature superconductivity. According to the message of the Foundation for advanced research and testing platform that includes battery, cables, current-limiting device and motor. The tests pass.

High temperature superconductivity is a phenomenon in which the electrical resistance of materials tends to zero under conditions of relatively high temperatures. They considered temperature range above 30 Kelvin (about minus 243 degrees Celsius). The materials showing properties of high-temperature superconductivity, in particular ceramics with the separated copper-oxygen planes.

It is assumed that due to the effect of superconductivity vysokotemperaturnoi it is possible to achieve efficiency of the motor and its feeder system of 0.98.

During the test, the superconducting motor has been fed only from the battery power. Experimentally proved that superconducting motors could be used as the traction at takeoff and landing, and in emergency mode. Details on the checks were not disclosed. Until the end of 2020 or 2021, the developers intend to begin testing the installation on a flying laboratory.

Superconducting propulsion system will be part of a hybrid power plant, which is the Central Institute of aviation motors named Baranov. The layout of a facility based on a superconducting engine was first presented at the MAKS air show in 2017. The developers plan to create superconducting installation with a capacity of up to 500 kilowatts.
