Abstract

Experimental techniques for aerodynamics have been essential tools for the development of rotorcraft. This includes wind tunnel, water tank testing, and flight testing. Rotor flows are rich in their physical complexity, and consequently an awareness of range of experimental methods is required. The chapter contains an introduction to wind tunnels, followed by a description of important experimental techniques, such as flow visualisation, pressure measurements, force and moment measurements, thermal anemometry and instrument calibration. Their performance and relative merits are discussed. Results are presented include forces and moments on a rotor, dynamic stall, particle-image velocimetry of a vortex ring state, and more.
