Development of an Active Vibration Supression System (AVSS) Using Combined Curved Flextensional and Shear Actuation

"The objective of this proposal is to demonstrate and evalulate the use of a Smart Monotoring Active Control System for Seeker-Platform Vibration Suppression designed for use in the Atmospheric Interceptor Technology (AIT) Kill Vehicle. This system isintended to afford a structural attachment interface between the seeker and the AIT forebody substructure. Advanced composite structures, employing embedded sensors and transducers, will be utilized as the atttachment interface and provide the ability toisolate the seeker from transient vibrations induces during shroud removal and divert and atitude control (DAC) operation. The resultant benefits to the AIT system performance include; 1) Elimination/minization of seeker blur due to transient vibration.2) AIT system design constraints driven by the seeker should be reduced thereby enabling simplified component design an fabrication. This program will investigate the utilization of imbedded sensors and transducers installed in situ during the compositefabrication process. This project presents advancements in the area of composite materials for high performance missile components/structures and will enable significient seeker performance improvement and AIT system weight and cost reductions. Commercialization potential for the technologies developed exists in many industries. Some possible areas include integrity monitoring of aerospase vehicles, ship structures, recreational equipment
