Development of a REBCO fully superconducting motor and cooling system, Applied Superconductivity Conference 2022, 2022.10, s a measure against global warming, aircraft are also required to have zero emissions. Simply changing the fuel of the current aircraft to liquid hydrogen will increase the volume of the fuel tank and reduce the payload due to the small energy density per unit volume of liquid hydrogen. In order to achieve zero emissions for aircraft, it is necessary to develop a compact, lightweight, and highly efficient electric propulsion system to actually realize distributed ducted fans as well as a blended wing body. The application of superconducting technology is indispensable for reducing the weight of electric propulsion systems. We are developing an electric propulsion system with a total output of 20 MW for 100-200 passenger aircraft such as B737 and A320 using REBCO high temperature superconducting wires. As proposed by NASA, it is a method in which a superconducting generator is rotated by a gas turbine, and the generated power is supplied to a superconducting motor via a superconducting cable and a low-temperature operation inverter. The fuel will be liquid hydrogen in the future. The refrigerant for superconducting systems is subcooled liquid nitrogen at 65 to 70K. Liquid nitrogen is cooled by heat exchange with liquid hydrogen. Three years ago, we successfully manufactured a 1kW fully superconducting synchronous motor by way of trial. The armature was cooled with subcooled liquid nitrogen, and the rotating field was cooled with helium gas which was maintained at a temperature around 70 K with subcooled liquid nitrogen. This time, we have completed the design of a 400kW fully superconducting synchronous motor that follows this structure and are currently manufacturing it. The casing is made of CFRP. Liquid nitrogen is cooled by heat exchange with liquid helium instead of liquid hydrogen. In this paper, the outline of the entire project is introduced and the progress of the current situation is reported..
