NUMERICAL ANALYSIS OF HIGH-SPEED IMPULSIVE (HSI) NOISE OF PZL W3-A “SOKÓŁ” (FALCON) HELICOPTER MAIN ROTOR IN FORWARD FLIGHT

NUMERICAL ANALYSIS OF HIGH-SPEED IMPULSIVE (HSI) NOISE OF PZL W3-A “SOKÓŁ” (FALCON) HELICOPTER MAIN ROTOR IN FORWARD FLIGHT

The paper presents the results of a numerical simulation of the flow and acoustic field generated by the PZL W3-A “Sokół” (Falcon) helicopter main rotor in high-speed forward flight conditions based on the URANS approach and the chimera overlapping grids technique. A refined CFD model (40+ million...
