Abstract
This paper studies the developments of urban air mobility with a focus on the configurations and flight mechanisms of the different vehicles in this field. This study contains twelve different common configurations in urban air mobility and reviews their advantages and disadvantages in order to provide a road map or prediction of the future of urban air mobility. It also reviews the major challenges in this field like infrastructure and the future of urban air mobility along with considering these major issues. At the end of the paper, a summarization is provided to compare the advantages and disadvantages of each configuration considering urban air mobility concerns.
