Název v původním jazyce

Influence of Propeller Blade Lift Distribution on Whirl Flutter Stability Characteristics

Popis výsledku v původním jazyce

This paper deals with the whirl flutter of the turboprop aircraft structures. It is focused on the influence of the blade lift spanwise distribution to the whirl flutter stability. Firstly it gives the overall theoretical background of the whirl flutterphenomenon. After that the propeller blade forces solution and the options of the blade lift modeling are described. The problem is demonstrated on the example of a twin turboprop aircraft structure. There are evaluated the influences with respect to thepropeller aerodynamic derivatives and finally the influences to the whirl flutter speed and the whirl flutter margin respectively.
