Development and preliminary assessment of the open-source CFD toolkit SU2 for rotorcraft flows

Computational aerodynamic analyses of rotorcraft main rotor blades are performed in both hover and forward flight. The open-source SU2 code is used for performance prediction. core the set RANS equations, which solved determining flow. In hover, steady-state time-accurate modelling techniques varying complexity assessed. Simulation specific parameters have a significant influence on solution also addressed. flight, developed to include blade kinematics prerequisite trimmed rotor. Two databases validation renowned Caradonna–Tung experimental tests model evaluate pressure distribution along during hover. extensive aeroacoustic data survey AH-1G Cobra helicopter assess at different advancing retreating azimuth angles prediction capabilities solver terms demonstrated overall good agreement with measured data.
