The purpose of the present study is to develop lightweight and simple smart actuators in order to replaceconventional hydraulic/pneumatic actuators, and to apply the developed actuators to the actuation systems of a smallunmanned air vehicle. This research describes the procedures of design, manufacturing of the piezo-compositeactuator, and the performance evaluation. From the test results of the developed devices, we found the possibility ofpiezo-composite actuator could be used as a control surface of a small UAV system. We have designed andmanufactured two kinds of piezo-composite actuators, unimorph actuator and bimorph actuator. The manufacturedactuators were evaluated through the performance testes. It was found that the bimorph type actuator showed morelinear angle change for the same excitation voltage variation than unimorph type. It is expected that piezo-compositeactuator has a possibility to be used not only as a control surface of small unmanned flying vehicle but also as acontrol surface actuator of a guided missile fin through the miniaturization of power supply and control system.초록 |
