This paper presents a study of the application of Navier-Stokes Computational Fluid Dynamics [CFD] to propeller aerodynamic problems. First, in order to show the aptitude of CFD for propeller applications, a CFD solution is compared to NACA wind tunnel data for a high-speed propeller. Second, the suitability of CFD in proprotor applications is shown through a comparison to NASA Tilt Rotor Aeroacoustic Model wind tunnel data. Finally, CFD models of the current V-22 proprotor configuration and Sikorsky Aircraft Corporation's Variable Diameter Tilt Rotor configuration are compared.
