Název v původním jazyce

Aeroelastic Demonstrator and Methodology for Experimental Investigation of Propeller Aerodynamic Derivatives

Popis výsledku v původním jazyce

Whirl flutter is a specific type of flutter instability, for which the experimental validation of analytical results is required. To determine propeller aerodynamic forces on a vibrating propeller, aerodynamic derivatives are used. Described demonstrator represents a sting mounted nacelle with a motor and propeller. It includes engine pitch and yaw degrees-of-freedom. For the measurement, a single degree-of-freedom model is used and blocking of either pitch or yaw movement is provided. Pitching moment and vertical force due to the pitch angle and pitching moment and vertical force due to the yaw angle derivatives are investigated. Measured quantities include pitch and yaw angles and pivot moments.
