    Scientists Develop a Unique Magnetic Suspension Generator for a Gas Turbine Plant

    A post-graduate student of South Ural State University presented his development of a fundamentally new generator design, which has a magnetic and gas-dynamic suspension. Such solutions have not yet been applied anywhere in the world. The development was awarded a grant from the Russian Foundation for Basic Research at the “Postgraduate” competition.

    Nikolai Neustroev, a postgraduate student of the Institute of Engineering and Technology under the guidance of D.Sc., Head of the Department of Electrical Engineering Sergei Gandzha, has proposed to implement a new design of an autonomous generator for a gas turbine plant. It can significantly reduce losses in electricity generation and increase the reliability of the unit.

    High-speed generators are a very promising scientific area. About 2,150 gas turbine units with a total capacity of 28 GW are annually used in Russia. Gas turbines have low maintenance, autonomous operation, high fuel efficiency and small dimensions. They are used in different spheres of human activity.

    “We propose to use a permanent magnet generator with axial magnetic flux and a diamagnetic armature. There is no steel core in it, which means there are no such problems either. The efficiency increases, the design is simplified and the price of the product is reduced,” Nikolai Neustroev explains.

    The high-speed generator with permanent magnets and axial magnetic flux on a magnetic gas-dynamic suspension has high efficiency due to the elimination of magnetic losses, it is energy efficient.

    The proposed concept can be applied in any field of technology: power supply of passenger airplanes, ships, on-board military equipment network, household power consumption needs. The original design modularity allows adjustment the required power due to additional sections.

    “At this stage, we are completing work on the creation of a “digital twin model”, since all the main components and assemblies must have three-dimensional solid-state virtual models for virtual tests,” the scientific advisor Sergei Gandzha says.

    The scientists intend to test their innovative idea in practice, that is, to make and test a prototype using the funds of the grant. A real sample model should confirm the concepts applied.

    The grant will help bring the research to its conclusion. The research results will be published in journals indexed by the scientometric databases Scopus and Web of Science (Q1 and Q2). The growth in the number of domestic developments and patents for inventions is provided for the Nauka national project, which should be implemented in Russia by 2024.
