Abstract
There is an increasing emphasis on incorporating smart materials into existing naval structures. Special purpose materials and devices which are a combination of active and passive materials are currently being designed for a wide variety of applications including space structures, control and noise reductions on helicopters, control and noise reduction system on conventional aircraft and quieting systems on submarines. Successful incorporation of active materials into addition to an understanding of the performance characteristics of the modified structure addition to an understanding of the performance characteristics of the un-incorporated active material. The latter does not provide sufficient information for the design of smart material. An understanding of the interactions between active and passive components is necessary for appropriate design of composite smart materials. This presentation will highlight issues which must be addressed in the design process. The basic device examined is an active panel. Different configurations of actuator placement have been evaluated for different applications. In two of the design cases discussed, prototype panels have been built and tested. The primary active components are PMN actuators. Typical displacement requirements are in the micrometer range. TRUNCATED
