"Simulation of a Wing-Tip Mounted Propeller Configuration from the Workshop for Integrated Propeller Prediction (WIPP)"

Propeller-driven engines have garnered renewed interest in the aircraft industry due to the emergence of electric and distributed propulsion systems. In addition, propellers mounted on the wing tips have been shown to significantly reduce the wing's induced drag by attenuating the wing-tip vortex by the propeller slipstream. An undesirable factor associated with propeller-driven engines is their noise level. In this talk, we present the latest simulation results for a wing-tip mounted propeller configuration using URANS, DDES and sliding mesh capabilities of SU2. The simulation reveals a number of important noise sources, namely the interaction noise caused by the turbulent wake and tip vortices from the propeller blades impinging on the wing and the nacelle surfaces transmitting unsteady aerodynamic loads.
