Description of a Simple Rotor Test Rig and Preliminary Wake Studies
Abstract
A simple test rig has been constructed, to obtain detailed rotor wake geometry data. The rotor head and blades have been taken from a radio-controlled model and attached to a 1HP 3-phase motor. The rotor and drive system were mounted on a rigid tripod-supported stand, and the rig used to obtain smoke flow visualization photographs of tip vortices within the rotor wake. These photographs provide vortex trajectories from which axial and radial coordinates of the vortex can be determined. The resulting data can be used to construct prescribed wake models for use in helicopter aerodynamics codes. Australia.
