Acoustic hemispheres were generated showing a dramatic reduction in noise levels compared to a overset structured grids for a wide variety of problems rotor helicopter, computed data using the HART20 blade XV-15 flight tests 23. formance analysis of the XV-15 tiltrotor blade is presented. Results are Very little wind tunnel data is available for model and full- scale tiltrotors. Multi-block structured meshes are used for HMB, which allow easy sharing of the the acoustic noise, BVI interactions, and in-ground effects.
