Current design tools for Urban Air Mobility (UAM) vehicle use empirical models that are based on historical data that is biased toward traditional VTOL vehicle configurations.   This results in inadequate models for design tools since most UAM vehicles have very non-traditional VTOL configurations. High-fidelity Computational Fluid Dynamics (CFD) simulations in support of NASA‘s Revolutionary Vertical Lift Technology (RVLT) project will be conducted. The candidate will carry out research into improving the current design tools, as well as developing new models for performance and acoustic analysis of new VTOL multi-rotor vehicle concepts. Areas of interest include high-fidelity CFD, acoustics, meshing, complex geometries, turbulence modeling and wake interactions.
