A high power density induction electromotor operating in the temperature range of 113 K – 120 K and utilizing the cryo-cooling capacity of bio-LNG fuel for thermal management is under development. Incorporating high current density Al conductor operating up to 120 K reduces its electrical resistance to 1/3 of room temperature and thereby increasing the motor’s power density. In this paper we...
Electrification has been proposed as a route to decarbonizing air travel. Conventional electric motors are too heavy to achieve the power densities required for aviation so superconducting motors for aircraft are being developed. Superconductors, however, work at cryogenic temperatures, which indispensably require a reliable and efficient cooling mechanism with a cryocooler. The successful...
Storage of liquid hydrogen at low pressures and temperatures is advantageous in terms of overall system weight compared to high-pressure gas storage at room temperature. The weight penalty for insulation of cryogenic media is typically outperforming the combined weight and volume penalty of high-pressure storage. For aviation applications, where light-weight and compact design is key, it is,...
