Paper Abstract

This paper considers two important application issues of fiber optic sensors in aircraft structures. The first concerns the interfacing of optical fibers with composite material structures: concepts have been developed for realizing a reliable exit point for the embedded fiber from a composite aircraft component, by means of single-mode connector assemblies embedded in composite material structures. The second issue relates to the temperature stability of the sensors: temperature characteristics of two-mode fiber optic strain sensors were investigated, sensors made of elliptical core and bow-tie fibers are compared, and the trade-offs among strain sensor range, sensitivity and temperature stability are discussed.
