A state-of-the-art review on eVTOL thermal management: system architectures, key components and emerging technologies
Electric vertical takeoff and landing aircraft (eVTOL) represent a transformative solution for modern transportation, offering high speed, low noise, and operational flexibility. However, the performance of their powertrains is highly temperature-sensitive, and their operating scenarios and mission profiles differ significantly from those of ground-based electric vehicles (EVs). In addition, cabin thermal regulation significantly affects energy consumption, thereby influencing the flight range. Consequently, an efficient thermal management system (TMS) is essential for eVTOL applications. This paper first reviews eVTOL powertrain architectures, followed by a systematic examination of the corresponding TMS architectures, including their operating principles, characteristics, and limitations. The thermal management requirements of key powertrain components are then analyzed, along with the review of relevant thermal management technologies. Moreover, emerging technologies applicable to eVTOLs are discussed, with an emphasis on their potential to enhance system performance. Finally, current research gaps are identified, and directions for future investigation are proposed. To the best of our knowledge, this is the first dedicated review of thermal management technologies for eVTOLs, aiming to clarify the state of the art, identify existing challenges, and provide valuable insights for researchers and industry practitioners.
期刊介绍:
eTransportation is a scholarly journal that aims to advance knowledge in the field of electric transportation. It focuses on all modes of transportation that utilize electricity as their primary source of energy, including electric vehicles, trains, ships, and aircraft. The journal covers all stages of research, development, and testing of new technologies, systems, and devices related to electrical transportation.
The journal welcomes the use of simulation and analysis tools at the system, transport, or device level. Its primary emphasis is on the study of the electrical and electronic aspects of transportation systems. However, it also considers research on mechanical parts or subsystems of vehicles if there is a clear interaction with electrical or electronic equipment.
Please note that this journal excludes other aspects such as sociological, political, regulatory, or environmental factors from its scope.
