The Noise Issues of Urban Air Mobility Industries and The Research Activities of KARI

As cities grow and population concentrate to big cities, ground mobilities face the capacity limit of passenger transportation and goods deliver. Recent day, new air mobility called urban air mobility (UAM) is emerging driven by the rapid developments of drone, electrical power, IT and autonomous technologies. But to develop and settle down this new urban air mobility as a new urban public transportation, various technical, legal and public barriers should be solved. One of the most important key barriers of UAM is the environmental noise impact of UAM operation. This noise impact can limit the permission and operation fleet of UAM not exceeding land use compatibility. Ultimately the perception by observers can be understood for community acceptance. In this paper, the global efforts of UAM industries and stakeholders for this noise impact are addressed and the previous VTOL aircraft noise research activities and future noise impact research plan of Korea Aerospace Research Institute (KARI) are introduced.
