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.

Economic Aspects of Aircraft Propulsion Electrification
Journal of Aircraft, 2021Aircraft 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 ...

Proceedings of the Institution of Mechanical Engineers, 1947
Mechanical flight began just over 40 years ago, and the only system of propulsion in use until five years ago was the internal combustion piston engine driving a propeller. Quite suddenly, the internal combustion turbine has come very much to the fore, both with and without a propeller, giving an increase in speed from under 500 to over 600 m.p.h.—a ...

Hydrogen for aircraft power and propulsion
International Journal of Hydrogen Energy, 2020Abstract Due to the fact that any type of aerospace vessel needs energy, and in the future, this energy must be nuclear and obtained by fusion, not by fission, this paper presents shortly a method by which nuclear fusion can be more easily achieved on an industrial scale.

Journal of Aircraft, 1972
Propulsion requirements for the next generation of civil aircraft are examined and some new and quite demanding needs are defined—larger engine sizes, higher takeoff thrusts, and much lower noise levels. The remarkable propulsion advances over the past two decades are charted and, from these, projections are made for the next round of improvements. All
