Research on the Flutter of Axial Turbomachine Blading.

Abstract

Typical aerodynamic moment and free flutter measurements are presented for thin airfoils in an annular cascade. For moment measurements, the parameters of significance were mean incidence angle, interblade phase angle and amplitude of oscillation. Since measurements take the form of a continuous record of moment versus angular position, the symbolic name 'moment loops' is used. For the free flutter measurements, the parameters of interest were stagger angle, incidence angle, torsional amplitude, and reduced frequency. The characteristics of the experimental data are discussed and comparison is made with earlier tested thick blades. (Author)
