Abstract

In the late 1980’s and early 1990’s smart structures seemed to be the only solution to add enough damping to the kind of lightweight, high performance beam director that was a key component of a Space Based Laser. This drove construction of what may be the world’s largest smart structure with 16-foot-long metering struts with 100’s and 100’s of embedded piezoceramics. The same technology was an excellent choice to make guitars sound better. Some current applications of smart structures at Boeing will also be discussed.
