Computational fluid dynamic(CFD) analysis is a powerful, cost-effective tool for the study of the aerodynamic characteristics of a flow. In this paper, applications of CFD in the analysis of rotorcraft were introduced. A three-dimensional flow solver based on unstructured meshes was used for the simulation and an overset mesh technique was applied to handle the relative motion between the main rotor and other components. The aerodynamic performance characteristics of a shrouded tail rotor and main rotor blade with vane tip was investigated. Unsteady flow simulations of a complete helicopter configuration were conducted and the aerodynamic interferences among main rotor, fuselage and tail rotor were investigated. A numerical study for the ground effect of a whirl tower rotor system and the drag prediction of a bearingless rotor hub were also performed.
