A parametric study of wing position, both downstream and vertical, was used to investigate the noise due to the interaction of a propeller’s wake with a wing for a tractor configuration propulsion unit. Numerical simulations were conducted via the SmartRotor code, a vortex particle method. Validation with experimental data showed that SmartRotor is effective for this type of simulation. Simulating a tractor-type configuration with a wing behind an SR-2 propeller in cruise configuration showed that broadband noise increased by 25 dB with little change in harmonic noise due to the addition of the wing. A parametric study on wing position was found that downstream position had little effect on noise while harmonic noise increased when the wing was moved vertically away from the propeller axis.
