摘要
This paper is focused on the influence of the propeller blade lift spanwise distribution on whirl flutter stability. It gives the theoretical background of the whirl flutter phenomenon and the propeller blade forces solution. The problem is demonstrated on the example of a twin turboprop aircraft structure. The influences on the propeller aerodynamic derivatives and the influences on the whirl flutter speed and the whirl flutter margin respectively are evaluated.
