Abstract
The rotor noise level is one of the main design parameters for future rotorcrafts. This fact requires accurate aeroacoustic prediction tools. The two most annoying contributers to rotor noise radiation are blade vortex interaction impulsive noise (BVI) and highspeed compressibility impulsive noise (HI). At DLR great effort is concentrated on these two impulsive noise phenomena.
