Abstract: In this paper the main objective of this simulation is to analyze the flow around an isolated main helicopter rotor at a particular main rotor speed of 400 rpm, and angle of attack of 8 degrees and blades of the helicopter Eurocopter AS350B3 which uses the blade profile of standard ONERA OA209 airfoil during hovering flight conditions. For CFD analysis, the Motion Reference Frame (MRF) method with standard viscous k-ε turbulent flow model was used on modeling the rotating rotor operating in hovering flight. The Ansys fluent was used for the purpose of analysis.

Keywords: Aerodynamics, CFD, helicopter, hovering, MRF, rpm.
