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 TRANQUIL SLEEP EXTRA STRENGTH in the context of a control law, in order to widen the flight envelope.In this way the main advantage of such a Upper Spray Arm Shaft piezo actuator, the bandwidth is exploited.
The mathematical model is obtained based on free body diagrams, and the numerical simulations allow a preliminary sizing of the actuator.
