The TecALSens project: new solutions for load sensors in aeronautics

In this paper the TecALSens project, developed within the Systems ITD of the Clean Sky 2 programme, is presented. The objective of the project is to design and validate a novel load sensor for aeronautic application based on thin-film sensing technology. So far, thin-film as sensing element has not been used in commercial aeronautic products: The outcome of this project tries to close this gap by providing a new class of load sensors complying with demanding aeronautic requirements. More and all electric aircraft configuration can benefit from the implementation of force measurement. This is an example of revolutionary approach to A/C design and a key enabler for achieving the environmental goals set by the European agenda up to 2050. Current project activities show very promising results: TecALSens provides a new approach to the design and manufacturing of load sensors for aeronautic applications. Especially, this new class of load sensors overcomes some of the drawbacks of strain gauge-based solutions. The final outcome of the project complies with the expected technology readiness level (TRL) 5. TecALSens outcome widens the possibilities offered by force sensing in aeronautics and strongly supports the evolution of aircraft design toward a more environmental friendly approach.
