Supravodivé spoje pre MgB2 vinutia v perzistentnom móde
Superconducting joints of MgB2 wires for windings in persistent mode
Program: VEGA
Project leader: Ing. Kováč Pavol, DrSc.
Annotation: The idea of this project is to make and optimize superconducting joints between the composite MgB2 wiresmanufactured by powder-in-tube method „PIT“ and by the infiltration or diffusion of magnesium into boronprocess „IMD“ and use it for winding working in „persistent mode“. It will be done dominantly for superconductingjoints of winding made by „wind and react“ technique, but joints for winding with already reacted MgB2 wiresmade by „react and wind“ process will be developed as well. The properties of manufactured superconductingMgB2 joints of different geometry and architecture will be subjected to mechanical and thermal treatments, which would reach the joint current around 50% of critical current measured for the reference MgB2 wire at external field 5 T.

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.
