The whirl flutter stability of a pusher propeller configuration immersed in the nonuniform flow field generated by many aerodynamic interference elements positioned upstream the propeller disk is analyzed. A panel method idealization for the complete aircraft, followed by a numerical integration of the propeller aerodynamic coefficients over the propeller disk allows the formulation of the problem in terms of the study of the stability characteristics of a periodic system, for which Floquet's theory can be efficiently applied.
