Abstract

To grasp effects of such ground effect parameters as rotor height, ground inclination angle, and location of the rotor hub center from the edge of ground plane, on blade flapping motion of a rotor hovering above finite inclined ground plane, a hovering test of the rotor was conducted using a finite ground effect plate and a model rotor. The thrust, torque, and blade flapping motion of the hovering rotor were measured for a wide variety of ground effect parameters. A very unique behavior of the blade flapping motion due to flow separation around a finite ground effect plate edge is clarified.
