Abstract

As populations become concentrated in cities, traffic congestion increases, and urban air mobility (UAM) is being considered to face this problem. Accordingly, many institutions and companies around the world are developing UAM vehicles, building infrastructure, and researching flight operating systems. In this study, three holding area concepts have been designed that can control air traffic flows and avoid bad weather conditions when UAM vehicles are operating. These holding areas have been considered to allow UAM vehicles to fly by avoiding collisions with other UAM vehicles or structures such as buildings. After validating the turning radius analysis with existing aircraft, a case study on the holding area concept design for the Seoul–GyungIn area was performed to determine whether UAM vehicles can turn within a narrow radius. It was not possible for winged-type UAM vehicles to turn across the Han River at cruise speed. The holding area concepts and the turning procedure of this study can be used as guidelines when designing UAM corridors or UAM flight routes.

Summary

Introduction

Urban air mobility (UAM) is an operating system of an air vehicle that carries people or materials and operates at low altitudes in and out of the city [1]. UAM corridors are being designed based on the performance of the UAM vehicles so that they can be operated safely and efficiently at low altitudes. It is necessary to establish a low-altitude holding area in order for UAM vehicles to perform holding procedures at a narrow-low altitude or to return to an alternative vertiport other than the destination vertiport due to air traffic management or for the avoidance of bad weather conditions. In the low-altitude environment where there are many obstacles and the area is narrow, the holding area should be clearly defined, including its length and radius. A conceptual design of low-altitude holding areas for UAM operations has been created based on Seoul and the suburbs of Seoul, Korea. Configurations and the performance of the aircraft capable of performing procedures in the designed holding area have been analyzed
