Complex and often violent urban wind environments pose a significant challenge to the safety and ride quality for vehicles intended for the Urban Air Mobility (UAM) market. UAM aircraft concepts must have control authority, turbulence rejection, and ride comfort as figures of merit at the forefront of the configuration selection process. However, the evaluation of handling qualities has traditionally been late in the design process when most of a vehicle's characteristics are established. Advanced design methods in early conceptual design are just recently adopting the use of physics-based aircraft dynamics models to identify handling quality metrics and educate the configuration down selection process. Attempts to extend those tools into unique VTOL configurations designed for the UAM market are not ubiquitous due to the increased complexity and diversity of VTOL concepts.Empirical Systems Aerospace, Inc., (ESAero) will develop a quantitative ride quality assessment methodology and accompanying tool suite to enable the analysis and down-selection of eVTOL configurations during the conceptual design process. ESAero will leverage previous development of 6DoF dynamics simulations of vehicles with distributed electric propulsion (DEP) control authority to integrate handling qualities into the design and configuration process where system level changes are least expensive. Physics-based models in ESAero’s Propulsion Airframe iNTegration for Hybrid Electric Research (PANTHER) tool suite will be extended to scalable dynamics models for the latest eVTOL propulsion technologies such as electric ducted fans (EDF) and small, distributed propellers. ESAero’s recent expansion of OpenVSP/VSPAERO to characterize handling qualities will be utilized in the creation of the dynamics simulations. By leveraging OpenVSP, PANTHER, and physics based 6DoF simulation, this effort will enable rapid evaluation of handling qualities at the forefront of the conceptual design process.
