Abstract

This paper presents an introduction to Fiber Bragg Grating (FBG) sensors and a typical application for dynamic tests in wind tunnels. Bench tests were carried out to measure the dynamic response of a cross-flexure pivot using FBG sensor and a conventional strain gage sensor simultaneously. The results suggest that FBG sensors, which are much easy to handle as compared to strain gages, can be effectively used for measurement of dynamic derivatives in a wind tunnel.
