CORRECTIONS OF AERODYNAMIC LOADINGS MEASUREMENT ON AIRFOIL CASCADE AT BENDING-TORSION VIBRATIONS

V. Tsymbalyuk, J. Linhart

Abstract

The paper describes improvement of the unsteady aerodynamic forces and moments measurements in an airfoil cascade. These loads are caused by shifting and angular vibrations of airfoils. The improvement was achieved by taking airfoils and other elements deformations, induced by action of innercia and measured aerodynamic firces, in consideration during the calibration and measurement process. The different variants of airfoils supporting are considered.
