In this article, computational Fluid Dynamics is used to study the complex interactions between the rotor and fuselage of the helicopter. Helicopter flows have been under investigation using isolated fuselage models, actuator disks as well as complete rotor-fuselage configurations. The paper highlights the flow detail that can be available to modern helicopter engineers equipped with modern software and computer clusters.
