Application of STAR-CCM+ to helicopter rotor hover

STAR-CCM+® Navier-Stokes solver has been applied to helicopter rotors in hover. Two tip planforms were analyzed: S-76 rotor with a swept tip and a swept tip with anhedral. The solidity of the three rotors was matched. Calculations have been done for a range of pitch settings. Comparisons of the measurements against computed thrust, power, and figure of merit values have been done. Where available, comparisons with other calculations. The simulations are in reasonable agreement with published data for the thrust, power, and figure of merit.
