title = "Strain-based aeroelastic shape sensing",
abstract = "The paper presents a numerical and experimental study of aeroelastic shape sensing using fiber optics sensors. Strain measurements via optical fibers are used to estimate a wing's deformed shape and modal displacements using a strain-to-displacement transformation algorithm. To test the performance of the algorithm and fiber optics sensors an elastic wing was designed and manufactured using rapid prototyping, and equipped with fiber-optics sensors of different technologies for strain measurements. The paper presents results from a static load testing and from wind-tunnel experiments in which the fiber-optics strain measurements were used to compute the deformed wing shape is static and dynamic conditions. The paper shows that the strain-to-displacement transformation algorithm, which requires knowledge of the structure's displacement and strain modes, can be applied successfully to aeroelastic systems, where the mode shapes vary with flflight conditions. The paper discusses aspects of application and accuracy of this shape-sensing technology.",
