Abstract

The S-76 and PSP rotor blades are simulated for a tip Mach number of 0.65 and a range of collective pitches using a structured, overset computational fluid dynamics solver. Grid generation and solution strategies are described for both rotors. Two different hybrid RANS/LES methods are used to predict the turbulence in the flow field, and the use of an advanced laminar-turbulent transition model is also explored. Predicted values of thrust, torque, and figure of merit are compared with experiment for the S-76 rotor. Qualitative assessments of the flow fields from the two turbulence modeling strategies are made and the impact of laminar-turbulent transition modeling is described. Predicted values of thrust, torque, and figure of merit are listed for the PSP rotor, and the behavior of its flow field is also assessed and compared to the S-76.
