Abstract

The recent increased interest in advanced air mobility (AAM), specifically within urban air mobility (UAM) and electric vertical take-off and landing (eVTOL) applications, has created a need to better understand and be able to predict the performance of these vehicles. Various configurations of AAM platforms are constantly being proposed, but the majority of them are based on a multi-rotor system consisting of single or coaxial rotors. This work summarizes a CFD model development using a hybrid BEMT and unsteady RANS flow solver, Rotorcraft CFD, which predicts rotor performance at a fidelity suitable for engineering design in a fraction of the time required by conventional CFD methods. Single and coaxial rotor configurations are presented using two-bladed KDE 30.5” rotors and are compared to test data obtained in the NASA Langley 14- by 22- ft. Subsonic Tunnel Facility. The simulations were run with both fully-turbulent and free-transition airfoil performance tables to quantify the associated uncertainty. Simulation results comparing an isolated single rotor to a coaxial rotor system are also presented.
