The Amplification Factor Transport model has been extended to include crossflow transition. Validation of the crossflow model implementation has been performed using standard test cases. Due to the innate rotationality and crossflow strength experienced, the S-76 and PSP rotors are simulated in hover for various collective pitch angles as test cases for the transition model. The OVERFLOW 2.2n solver is used with laminar-turbulent transition modeling and hybrid RANS/LES enabled. Grid generation, numerical methods, and transition modeling are described. The effects of crossflow transition is qualitatively and quantitatively assessed through comparisons to experiments and to a transition model without crossflow.
