A Survey:Typical Scenes and Corresponding Technology Challenges in UAM

Abstract

Urban Air Mobility (UAM) is a new type of transportation delivery system based on highly automated drones operating at low altitude in urban or suburban areas. Aimed at finding out what directions current researches are focusing on and what directions can be considered as the future researches, this study integrates several papers about two typical scenes in UAM including air taxi and air emergency supplies delivery as well as three technological challenges in above scenes to find out what kind of directions are not mentioned. Firstly, we explain the definition of UAM and display a list of real cases of the current situation of UAM development. Secondly, researchers are focusing on the path optimization and single demand on the aircraft. However, they pay less attention on the interactions between the existing systems, and the supporting system also turned out to be a blank research direction. Thirdly, we mentioned three main technological challenges including battery problems, noise problems and non-GPS problems. Not only by giving the reason why those challenges came up, also scholars pointed out some feasible solutions. Finally, it’s evidently that electric Vertical Take-Off and Landing technology (eTVOL) got a batter develop in the UAM. However, researches about mating installations are a few by comparison. Opening up those potential factors in UAM can not only boost the whole system, also it can solve several technological problem.
