• 論文の詳細を見る

• Unsteady aerodynamic damping force on compressor blades and vanes, vibrating with a bending, a torsion or a panel (chordwise stripe) mode, was investigated both experimentally and theoretically. The aerodynamic damping force was measured using piezoelectric ceramics attached on an inlet guide vane to compare response characteristics at operation and at rest. The damping force was obtained theoretically by the combination of a singular method to obtain unsteady aerodynamic forces with Lagrange method to obtain vibration response. Experimental and theoretical studies show that the panel mode has a much smaller aerodynamic damping coefficient compared with the bending and the torsion modes.
