Vibration Control of Optical Components in Missile Guidence Systems using PZT Fiber Composites

"The proposed program will investigate the feasibility and benefits of an efficient piezoelectric (PZT) vibration control system for electrical/optical guidance component mounts in seeker missiles. The Phase I objective will investigate a through thicknessPZT rod/fiber architecture for composite optical benches in the seekers. The study will concentrate on the typical seeker missile vibrations generated from three environmental scenarios: aircraft carry, flyout, and homing. Increased performance,reliability and improved resolution of the optical train is the expected outcome of using the PZT composite. The Phase I paper study will model and examine the use of combination PZT fiber and rod composites as combined sensors and actuators integratedwithin existing structural components. The final benefit of the a Phase II endeavor will bring increased resolution, reliability, and accuracy to seeker missile optical functions. The Phase I investigation of PZT sensors/actuators to reduce vibration ofseeker missile electronic housings is expected provide specific feasibility information of improving the efficacy of a range of similar structures."
