Piezo-Composite Actuated Control Surface System for Flying Vehicle

Nam Seo Goo, Taesam Kang, Kwang Joon Yoon

Abstract


This study aims to develop lightweight actuators in order to replace conventional hydraulic/pneumatic actuators and to apply the actuation system to a small flying vehicle. A new type of control surface using a piezo-composite actuator for a small flying vehicle has been designed and manufactured. The piezo-composite actuator is composed of a piezoelectric ceramic layer, a carbon/epoxy layer and glass/epoxy layers. Through this, the miniaturization and weight reduction of the actuation systems for flying vehicle can be achieved. A simple model of the control surface was manufactured and evaluated through experiments. The performance test results showed that the developed actuator can produce stable angle of attack independent the applied loading. A radio controller for the actuator was developed to control the motions wirelessly. It was found that the piezo-composite actuator and its integrated controller system have a possibility to be used not only as a small flying vehicle but also as a control surface actuator of a small unmanned flying robot through the miniaturization of power supply and control system.
