Bergh, H. (author), van der Wekken, A.J.P. (author)In a low-speed windtunnel flutter tests are performed with a driven model rotor, consisting of one rigid blade hinged at the root by a weak bendingtorsion spring. Many flutter points in non-stalled and stalled flow are measured with three different model configurations by changing the rotor speed at constant tunnel velocity. Aerodynamic...report 1985
