Electric/Hybrid-Electric Aircraft Propulsion Systems
Proceedings of the IEEE, 2021The idea of electric propulsion for transportation is not new; indeed, the first cars, nearly 200 years ago, were electric. However, our dependence on fossil fuels over the last 100 years is now being questioned, and as a global society, we are moving toward more-electric transportation solutions.
