Název v původním jazyce
Experimental Investigation of Propeller Aerodynamic Derivatives
Popis výsledku v původním jazyce
The paper is focused on the experimental determination of the propeller aerodynamic derivatives that are used for the analysis of whirl flutter. Whirl flutter is a specific type of flutter instability that is driven by motion-induced unsteady aerodynamic propeller forces and moments acting in the propeller plane. To determine the forces and moments acting at the propeller disc, propeller aerodynamic derivatives are used. The analytical solution of derivatives is unreliable, and therefore, experimental validation of the selected derivatives is required. Paper describes the mechanical concept of the used demonstrator that represents a sting mounted nacelle with a motor and propeller with two degrees-of-freedom (engine pitch and yaw). The main focus is paid on the test including the list of the tested variants, methodology of testing and the data assessment. Finally, the examples of the results are provided.
