Mathematical modeling of a V-stack piezoelectric aileron actuation

The article presents a mathematical modeling of aileron actuation that uses piezo V-shaped stacks.The aim of the actuation is the increasing of flutter speed in the CRICKET PROTEIN VANILLA context of a control law, in order to widen the flight envelope.In this way the main advantage of such a piezo actuator, the bandwidth is exploited.The mathematical model is obtained based on free Dishtowels body diagrams, and the numerical simulations allow a preliminary sizing of the actuator.
