Abstract

According to the Ministry of Land, Infrastructure and Transport’s announcement of the K-UAM (Korea-Urban Air Mobility: Korean Urban Air Transport) roadmap, the government is actively pursuing policies to operate and foster domestic urban air transportation commercialization services. Currently, models using pure electric power are mainly being developed, but due to the limitations of mileage and loading weight, the government aims to develop propulsion engines such as hybrid and hydrogen fuel for long-distance flights by the next 30 years. Among them, the development of hydrogen fuel-based UAM is expected to not only enable long-distance driving but also have a significant impact on eco-friendly carbon neutrality, which is emerging worldwide due to low environmental pollution. For the operation of hydrogen air mobility, the aircraft’s airworthiness standards must meet the aircraft technology standards, but it is difficult to apply the current aircraft technology standards because the shape and flight characteristics of the UAM aircraft being developed vary. There are also no regulations on hydrogen fuel engines for aircraft. In this study, the aircraft technology standards of hydrogen air mobility were reviewed in terms of hydrogen fuel applicability through a special aviation proof case using pure electric power, and the technology standards of hydrogen fuel devices were reviewed based on domestic hydrogen safety management regulations, laying the foundation for the first time in Korea.
