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.

Hybrid electric chemical propulsion
21st Joint Propulsion Conference, 1985Abstract : A spacecraft propulsion concept that uses a combination of electrical energy and chemical energy for thrust is explored using thermodynamic modeling calculations. The essence of this concept consists of adding a carefully chosen amount of O2 or F2 oxidizer to the propellant flow of a conventional H2 electrothermal thruster.

A Hybrid Power System Laboratory: Testing Electric and Hybrid Propulsion
IEEE Electrification Magazine, 2019International shipping contributes to a major portion of global emissions. This is expected to grow at a faster pace due to economic and population growth. According to the Third Greenhouse Gas (GHG) Study 2014 of the International Maritime Organization (IMO), the total shipping emissions during 2007-2012 were 3.1% of global CO2 emissions, 2.8% of ...

Electric and Hybrid-Electric Propulsion Systems
2013While in conventional ICE-based vehicles the energy carrier is a fossil fuel, electric and hybrid-electric propulsion systems are characterized by the presence of an electrochemical or electrostatic energy storage system. Moreover, at least one electric motor is responsible — totally or partially — for the vehicle propulsion.

Design of a Hybrid Electrical Propulsion System
52nd AIAA/ASME/ASCE/AHS/ASC Structures, Structural Dynamics and Materials Conference, 2011The focus of this work is on exploring the design of an aircraft hybrid propulsion system by integrating a gas turbine engine with an electric motor assisted by solar power. We discuss how the two systems can work in tandem while optimizing the efficiency.
