Abstract:

A dynamically scaled model rotor, 9 feet in diameter, was tested in an 18-foot wind tunnel. The purposes of the test included the determination of rotor transient response to sudden control inputs, the investigation of blade aeroelastic limits, and the generation of detailed dynamic data for the evaluation and improvement of theoretical calculations. The rotor was of a conventional articulated type. Author
