Title:
Investigations of helicopter wake flow including rotor-head motion 
Abstract:
The present paper emphasizes on the characteristics of the wake flowfield emanating from a helicopter fuselage and rotor head, including cyclic and collective pitch motion. Predicting the convection of the coherent vortical flow structures generated by the fuselage as well as the rotor head is a difficult goal by the application of numerical methods. Furthermore, the accurate determination of the wake flowfield requires the detailed knowledge of the origin of the associated coherent structures....    »
