Vysokoteplotná supravodivá cievka pre motory elektrických a hybridných lietadiel
High temperature superconducting coils in motors for electric and hybrid aircrafts
Program: SRDA
Project leader: Mgr. Pardo Enric PhD.
Annotation: Full superconducting electric motors are very promising to provide therequired power density to enablecommercial hybrid and electric airplanes. These can reduce emissions by75 % in CO2 and 90 % in NOx, followingthe ACARE Flightpath 2050 targets of the European Union. Superconductingmotors can also be applied to cleanersea or sweet water transport. In spite of the extensive research in thearea, the electro-magnetic and electro-thermal properties of superconducting coils in the motor magneticenvironment remain largely unknown, partiallybecause of the lack of measurements of the relevant temperatures(between 20-40 K) and modeling methods forfull superconducting motors.The aim of this project is to gain this understanding and develop numerical modeling methods to enable the design of future superconducting motors. These methods will be compared to experiments in the relevant temperature range for motor applications.

Magnetická interakcia supravodivých a feromagnetických vrstiev: modelovanie, charakterizácia a aplikácie
Magnetic interaction of superconducting and ferromagnetic layers: modelling, characterization and applications
Program: VEGA
Project leader: Mgr. Seiler Eugen PhD
Annotation: The project aims to investigate the mutual magnetic interaction between superconducting and ferromagneticlayers. Theoretical investigation will rely on numerical models based on the Finite Element Method and theMinimum Electro-Magnetic Entropy Production method. The project will greatly improve the capabilities of thenumerical methods, enabling accurate modelling of real geometries.Experimental investigation is based on characterization of the individual superconducting and ferromagneticlayers and on characterization of simple compound structures, with emphasis on conditions of AC field.Commercially available superconducting tapes will mainly be used as the superconducting elements andcomposites containing ferrite powder will mainly be used as ferromagnetic elements.Using the developed numerical models, the project will analyze and optimize motors with superconductingwindings, as well as design and construct improved magnetic cloaks for shielding AC field.
