Electric/Hybrid-Electric Aircraft Propulsion Systems

Proceedings of the IEEE, 2021
The 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.

Economic Aspects of Aircraft Propulsion Electrification

Journal of Aircraft, 2021
Aircraft propulsion electrification is currently being considered by industry and academia as one of the most promising strategies to reduce air transport emissions and increase overall efficiency levels. In the past decade, several papers were published on this subject, with the majority indicating encouraging fuel burn benefits versus conventional ...
