Efficiency of an intermittent, flexible propeller

In this talk, I will present a study addressing the problem of propulsion using intermittent dynamics. The system consist of body moving forward using a propeller that has the possibility of changing shape depending on whether the propeller is rotating or not. The nature of the intermittent dynamics consist of alternating active phase (when the propeller in rotating) and passive phase where the body uses inertia to sustain the motion.
