What is it about?

At certain conditions, stall on propellers may develop and trigger a violent motion of their blades. This phenomenon is a kind of flutter and is unique to highly loaded rotating lifting surfaces. Simulations using detailed flow aerodynamics and finite element representation of the structure are shown here. The method is validated against tests for the Commander aircraft propeller and is general enough to be used for the study of similar flutter phenomena.
