  In this paper, we developed a generalized simulation framework for the
evaluation of electric vertical takeoff and landing vehicles (eVTOLs) in the
context of Unmanned Aircraft Systems (UAS) Traffic Management (UTM) and under
the concept of Urban Air Mobility (UAM). Unlike most existing studies, the
proposed framework combines the utilization of UTM and eVTOLs to develop a
realistic UAM testing platform. For this purpose, we first enhanced an existing
UTM simulator to simulate the real-world UAM environment. Then, instead of
using a simplified eVOTL model, a realistic eVTOL design tool, namely SUAVE, is
employed and an dilation sub-module is introduced to bridge the gap between the
UTM simulator and SUAVE eVTOL performance evaluation tool to elaborate the
complete mission profile. Based on the developed simulation framework,
experiments are conducted and the results are presented to analyze the
performance of eVTOLs in the UAM environment.
