The future of electric aircraft and deep space missions will rely on our ability to develop electrical and electronic components that can operate at the very low temperatures of the upper atmosphere and the cryogenic temperatures of space. A review of such technology is presented in the International Journal of Powertrains. The review looks specifically at semiconductor devices, passive components, and superconducting devices that operate at very low temperatures.
Mustafeez Ul-Hassan, Yalda Azadeh, Asif Imran Emon, and Fang Luo of the Department of Electrical and Computer Engineering at Stony Brook University, New York, U.S., point out that in terms of aeronautics and space travel there is a pressing need to usurp pneumatic, hydraulic, and mechanical systems with electrical components.
In terms of aircraft, such components will operate at the low temperatures of high-altitude flight, but also benefit from being held at cryogenic temperatures in terms of improving their efficiency. Indeed, the development of superconducting technology that by necessity operates at such temperatures would not only make electric aircraft more feasible and improve space travel option but improve the generation efficiency of wind turbines.
