Holographic Characterization of the Dynamic Structure of a Graphite- Epoxy Composite Missile Flight Control Assembly

摘要

Holographic Interferometry has been successfully employed to characterize the materials and behavior of diverse types of structures under stress. Such applications of holographic technique offer some of the most effective methods of dynamic structural analysis available. Real-time dynamic testing of aerodynamic control structures for advanced missiles systems has always required advanced instrumentation for data collection in either actual flight test or wind-tunnel simulations. Advanced optical holography techniques are alternate, non-invasive methods which define actual behavioral data on the ground. These methods offer significant insight in both the development and subsequent operational test and modeling of advanced composite control structures and their integration with total vehicle system dynamics. Structures and materials can be analyzed with very low level stresses and the resultant data used to determine operational acceptance and adjust the accuracy of mathematically derived structural models.
