Purpose and goal
The project has developed a fiber optic sensor for detecting overheating, a so-called Over Heat Detection System (OHDS). The detection system targets the commercial aviation industry. Fiber optical sensors based on FBG technology have been developed. Processes and methods for manufacturing and protecting sensors with lengths longer than 35 meters have been developed within the project.
Expected results and effects
The project´s expectation is that the system for detecting overheating via fiber optic sensors will replace the traditionally based electric sensors within a three-year period. Thus the sensors are more accurate as well as weigh less. Further expectation is that the number of fiber optic sensors in the aviation industry will increase in other applications as well.
Planned approach and implementation
We believe that the distribution between stakeholders such as research institutes, small companies and large companies has been significant in order to implement this project in a well-functioning way. We note that the project has taken considerably longer time than expected and that each part has required more resources than estimated. This has resulted in certain re-prioritization and adjustments being made during the project.
