A fluid power actuation system for shape control of an elastic rod
Guran A.
pages 129 - 132, full text

Fluid power actuators receive fluid from a pump (typically driven by an electric motor). After the fluid has been pressure, velocity, density, and directionally controlled, the actuator converts its energy to do useful work in various applications. In this paper a system of reversing channels embedded into an elastic rod is developed using fluid power as a continuous actuator. By adjust the fluid velocity, density, and eccentricity path of channels the shape and the deflection curve of the rod can be controlled. The governing equation of the equilibrium of the rod is obtained and the numerical solution for a parabolic eccentric path is presented. The extension of the present work is in design of modern aircraft wings for getting higher lift or drag at the time of take off or landing.
