Improved Solution of the Propeller Blade Force for Whirl Flutter Analysis

Original language description

The topic of this article is the whirl flutter of turboprop aircraft structures; more specifically, the improved solution of the propeller blade forces that is used in whirl flutter analysis. First, an overall theoretical background on the whirl flutterphenomenon is provided. Next, a solution of the propeller blade forces and the applicable options of blade force modelling are described. The solution to an example problem of a twin turboprop aircraft structure is presented. The influence on the propeller aerodynamic derivatives and the influence on the whirl flutter (flutter speed and flutter margin) are evaluated.
