Abstract:
Experimental investigations are performed on a helicopter wind tunnel model for three rotor heads with different blade stub lengths. This investigation is intended to judge the influence of the blade stub spanwise dimension on the drag, lift, and especially pitching moment characteristics. Aerodynamic forces, moments, and the wake flow fields are analyzed. As expected, the longest blade stubs provide the highest drag and lift coefficient along the angle of attack polar, while both shorter blade...     »
