Purpose and goal

In close cooperation with the aviation industry, develop and verify system-critical temperature monitoring systems for detection of overheating in civil aircraft. The ambition is to replace today´s electrical sensors used to monitor pipes transporting hot air from jet engines to different parts of the aircraft with distributed fiber optic temperature sensors. Thereby creating a fiber optically based commercial aircraft monitoring system. The electrical systems have several fundamental limitations while a distributed measurement is system critical.

Expected results and effects

The project results in a complete system that will be delivered to the intended aircraft manufacturer for system tests in the test bench (on non-aerated reading equipment). This involves developing and qualifying sensors, developing critical parts of readout equipment, and implementing own system tests. In a broader sense, the project involves brand new knowledge that enables longer, more high-resolution fiber optic sensors in combination with a fast monitoring system. In line with the strong market demand for systems for demanding environments.

Planned approach and implementation

The idea of the project is to take knowledge and experience from newly developed distributed temperature monitoring systems to develop the corresponding systems for commercial aviation industry. In 2017, Proximion answered a procurement of the intended system from one of the two major aircraft manufacturers. In order to reduce both commercial and technical risk, Proximion collaborates with research institutes and private actors with specific expertise, and builds on the development project with SAAB acting as a reference group and is intended for future system owners.
