A method is presented for using LES to generate urban wake fields for use in studying their effects on autonomous quadrotor's flight performance. The flow field is generated around a single square building using OpenFOAM, and a MATLAB/Simulink flight simulator is used to compare the difference in flight performance between wake fields generated by RANS and LES. It is found LES causes maximum position deviations 2 orders of magnitude larger compared to RANS, and results in skewed deviations by as much as 5 to 1 in a given direction. Since the transient turbulent LES wake field more accurately reflects the flow present behind real world structures, LES generated wake fields should be used when designing and testing autonomous control algorithms for multirotor UAVs on the order of 0.5 m in size and 2 kg in mass.
