Keywords: propeller, open rotor, aerodynamics, performance, installation effects

ONERA has developed and validated computational tools which aim at predicting the aerodynamic performance of propellers and open rotors. The objective of this paper is to discuss the strengths and weaknesses of these approaches (ranging from simple lifting-line theory to 3D CFD), through validation against experimental data when available.
