Power Supply Solutions to Enable the Development of eVTOL Aircrafts 2023-01-1015

The aerospace industry is undergoing a revolution with the large-scale development of eVTOL (Electric Vertical Take-Off & Landing) and MEA (More Electric Aircraft). These aerial vehicles, many of them unmanned vehicles (UAV), will serve a variety of service-related functions: Search and Rescue (SAR), Medivac, delivery and lift operations, aerial mapping, and, of course, human transportation [1].

Despite its numerous functionalities, this type of vehicle has a serious problem, which is its usual batteries, the main means for its operation. Due to its autonomy not being so effective compared to its charging time, generating a considerable loss of time. In this context, it is necessary to find forms of components that can replace these batteries, so that the effective development of these vehicles is possible.

Studies done in other means of transportation point out that the use of hydrogen fuel cells has grown a lot. In this way, it is known that this type of fuel is seen as something of the future, but many companies have evaluated the possibility of implementation in cars, trains, and even airplanes. Therefore, a literature review will be presented about this new type of technology, demonstrating its advantages and its use. Finally, after careful analysis of the issues highlighted throughout the article, the best effective solution for replacing the batteries will be presented, a component that has caused major problems for the developers of this new aircraft [28].
