Abstract:
Experimental and numerical investigations have been performed on a helicopter wind tunnel model for three rotor heads with different blade stub lengths. This investigation analyzes the origin and the development of the wake structures occurring from the various blade stub lengths and their interaction with the tail section of the helicopter to judge the influence of the blade stub spanwise dimension on drag, lift and pitching moment characteristics. Therefore, aerodynamic forces and moments and...     »
