Therefore, structural health monitoring has a great potential to reduce the costs related to these operations. Optical fiber sensors applied to the monitoring of aircraft structures provide some advantages over traditional sensors. Several practical applications for structures and engines we have been working on are reported in this article. Fiber Bragg gratings have been analyzed in detail, because they have proved to constitute the most promising technology in this field, and two different alternatives for strain measurements are also described. With regard to engine condition evaluation, we present some results obtained with a reflected intensity-modulated optical fiber sensor for tip clearance and tip timing measurements in a turbine assembled in a wind tunnel.<\/jats:p>","DOI":"10.3390\/s150715494","type":"journal-article","created":{"date-parts":[[2015,6,30]],"date-time":"2015-06-30T11:40:13Z","timestamp":1435664413000},"page":"15494-15519","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":203,"title":["Optical Fiber Sensors for Aircraft Structural Health Monitoring"],"prefix":"10.3390","volume":"15","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-4217-7643","authenticated-orcid":false,"given":"Iker","family":"Garc\u00eda","sequence":"first","affiliation":[{"name":"Department of Communications Engineering, E.T.S.I. of Bilbao,  University of the Basque Country UPV\/EHU, Alda.
