Paper Abstract

This paper reviews the smart structures and avionics research and teaching program at Virginia Tech. Started in 1979 with support from the NASA Langley Research Center, this program has grown to include interdisciplinary participation between more than twenty faculty from seven departments in the Colleges of Engineering and Arts and Sciences, graduate and undergraduate engineering classes which specifically address smart structures issues, and directed research programs conducted in cooperation with more than a dozen aerospace companies and government organizations. Current smart structures research includes major efforts in 1) the development of embedded and attached optical fiber and acoustic fiber sensors for a wide range of applications including cure monitoring, in-service lifetime structural monitoring, nondestructive evaluation, and impact and damage detection and analysis, 2) sensor signal multiplexing, processing and data handling to achieve near real time distributed structural analysis, and 3) the combined use of embedded or attached sensors and actuators to achieve controlled structural response. Special campus facilities which have been used for this work include an optical fiber fabrication facility, an autoclave for composite structure fabrication and curing, and laboratories for optical fiber sensor development, materials response and non-destructive evaluation, structural control testing, and computer engineering. The work in all of these areas during the past few years by different Virginia Tech faculty, staff, graduate student and visiting scientist groups is reviewed.
