Experimental Investigation of Three Rotor Hub Fairing Shapes
Abstract
A series of subsonic wind tunnel evaluations were undertaken to establish minimum drag fairings for helicopter hubs as part of the Helicopter drag Technology Program. The data reported were taken to investigate the flow phenomena affecting helicopter rotor hubs. Three large, 25 percent thick, analytically faired hubs were evaluated (both with and without simulated rotor blade shanks) over a wide range of angles of attack at full scale Reynolds numbers. Forces, moments, and pressures were measured on the hubs.
