Simultaneous Active Damping and Health Monitoring of Aircraft Panels

The concept of using the same hardware to perform both structural health monitoring and control simultaneously is explored. Aircraft panels often require damping treatments in order to reduce fatigue. At the same time, manufacturers are starting to use health monitoring as a basis for maintenance. Here, an example of doing simultaneous health monitoring and control on a sample plate is presented as experimental evidence that both functions can be performed with the same set of hardware. In this case, smart materials, a piezoceramic patch (PZT) and a fiber optic sensor, are used as the common hardware.
