Computational Study on the Aerodynamic Interference Between Tandem Rotors and Nearby Obstacles

What is it about?

Rotorcraft have the ability to take off and land vertically, hover, and taxi near the ground, they frequently operate in ground-effect environments and close to obstacles. Nevertheless, the aerodynamic interference between rotorcraft and the ground generates unsteady airloads on the rotor blades and degrades performance. Thus, the complex tandem rotor/ground-obstacle interference is investigated, and the airloads, flow fields, and wake of the tandem rotor with the obstacle located at different positions are analyzed.
