We applied invers analysis to identification of distributed loads on6-m CFRP wing structure and 1-m aluminum wind tunnel model. These structures were equipped with fiber-optic strain sensors and the applied loads were estimated based on strains measured by the sensors. Seven fiber-optic strain sensor arrays which have 30 ? 40FBGs in each were bonded on the wing in the longitudinal direction. Measured strains show excellent accuracy and the estimated load coincided with the actual one. In the wing tunnel model, the applied pressure distribution could be also estimated by several fiber-optic strain sensors which can measure strain at an arbitrary position along fibers.
