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.

Hybrid electric chemical propulsion

21st Joint Propulsion Conference, 1985
Abstract : 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.

Hummingbird Hybrid - Micro Hybrid Electric Aircraft Propulsion System

2021
The Hummingbird Gas Turbines (HGT) student research group focuses on the research on small gas turbines. In line with global trends in aviation, HGT is exploring a possible path towards minimising noise and carbon emissions. To this aim, the group is developing the Hummingbird Hybrid, a series hybrid configuration test bench rated at 5 kW electric ...

Hybrid-Electric Propulsion for Aircraft

Journal of Aircraft, 2015
Against a background of increasing energy demand and rising fuel prices, hybrid-electric propulsion systems have the potential to significantly reduce fuel consumption in the aviation industry, particularly in the lighter sectors. By taking advantage of both electric motor and internal combustion engine, hybrid-electric propulsion systems provide not ...

A Hybrid Power System Laboratory: Testing Electric and Hybrid Propulsion

IEEE Electrification Magazine, 2019
International 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 ...
