Abstract
Urban Air Mobility (UAM) is a new air transportation system for passengers
and cargo in urban environments, enabled by new technologies and integrated
into multimodal transportation systems. The vision of UAM comprises the mass
use in urban and suburban environments, complementing existing transportation
systems and contributing to the decarbonization of the transport sector.
Initial attempts to create a market for urban air transportation in the last
century failed due to lack of profitability and community acceptance.
Technological advances in numerous fields over the past few decades have led to
a renewed interest in urban air transportation. UAM is expected to benefit
users and to also have a positive impact on the economy by creating new markets
and employment opportunities for manufacturing and operation of UAM vehicles
and the construction of related ground infrastructure. However, there are also
concerns about noise, safety and security, privacy and environmental impacts.
Therefore, the UAM system needs to be designed carefully to become safe,
affordable, accessible, environmentally friendly, economically viable and thus
sustainable. This paper provides an overview of selected key research topics
related to UAM and how the German Aerospace Center (DLR) contributed to this
research in the project "HorizonUAM - Urban Air Mobility Research at the German
Aerospace Center (DLR)". Selected research results that support the realization
of the UAM vision are briefly presented.
