A Review of Concepts, Benefits, and Challenges for Future Electrical Propulsion-Based Aircraft

Abstract

Electrification of the propulsion system has opened the door to a new paradigm of propulsion system configurations and novel aircraft designs, which was never envisioned before. Despite lofty promises, the concept must overcome the design and sizing challenges to make it realizable. A suitable modeling framework is desired in order to explore the design space at the conceptual level. A greater investment in enabling technologies, and infrastructural developments, is expected to facilitate its successful application in the market. In this review paper, several scholarly articles were surveyed to get an insight into the current landscape of research endeavors and the formulated derivations related to electric aircraft developments. The barriers and the needed future technological development paths are discussed. The paper also includes detailed assessments of the implications and other needs pertaining to future technology, regulation, certification, and infrastructure developments, in order to make the next generation electric aircraft operation commercially worthy.

Electric Power Systems in More and All Electric Aircraft: A Review

“…The paper, however, was not prepared from an electrical engineering point of view and did not go beyond the basics. Authors in [15] focused on electric propulsion and provided a review on presented concepts and challenges for future electric propulsion concepts. Other papers exist that present reviews on subjects related to MEA/AEA.…”

“…It was not intended for EPS in its first revision; however, the ability to design, analyze, and integrate EPS components [30] enables NPSS to be a powerful software to wholly analyze the power system and propulsion system in MEA/AEA. Finally, readers can refer to [15], [31]- [34] to find more references for further study about DPS.…”

Dimensionamento e arranjo de baterias em um sistema de propulsão aeronáutica e as tendências para o futuro

“…No entanto, foi utilizada na fase de projeto preliminar para estimar a fração de peso de baterias. Traub (2016) e Sahoo et al (2020) tratam do mesmo tema de Hepperle e na primeira obra busca-se a fração de massa de bateriaótima para a aeronave, enquanto na segunda modelam-se o alcance e autonomia porém, considerando as variáveis citadas no parágrafo anterior, como mostra a Equação 4 e 5. Resultados semelhantes podem ser observados também por Avanzini and Giulietti (2013)…”

Using Dfferential Evolution Techniques for Management of a Hybrid-Electric Propulsion System

“…The term hybrid-electric on aircraft propulsion defines a technology where more than one type of energy source is employed, traditionally fuel/chemical and battery/electrochemical (Sahoo et al, 2020;Assanis et al, 1999). Most HEPS employ internal combustion engines (ICE), which are usually over-sized to meet requirements in certain stages of the flight, which renders high fuel consumption in the whole mission (Assanis et al, 1999).…”
