Abstract

Hover predictions of the Hover Validation and Acoustic Baseline (HVAB) rotor are made using a computational fluid dynamics approach. Solutions are generated using the NASA OVERFLOW 2.2n solver with both hybrid RANS/LES and laminar-turbulent transition modeling enabled. Solutions are based on a hover tip Mach number of 0.675 for a pre-deformed rotor with prescribed collective pitch, lag, and coning angles. Grid generation and computational methods are described. The rotor flowfield is analyzed and the effect of the transition model is assessed through comparison to predictions made using a fully-turbulent modeling approach.
