REPRISE (H2020) – Reliable Electro-mechanical actuator for PRImary SurfacE with health monitoring

2016-2019 REPRISE – Reliable Electro-mechanical actuator for PRImary SurfacE with health monitoring
Funded by the European Union (H2020) Clean Sky 2 Joint Technology Initiative
Work programme topics addressed JTI-CS2-2015-CFP02-SYS-03-01
3 partners, total budget 995.000 Eur, 36 months (July 2016-June 2019)

This project is part of the research for the development of electric actuators for primary flight surfaces of small aircrafts. The main objective is to develop condition assessment algorithms, that are able to provide indications on the current “health status” of the electromechanical component, giving quantitative indications for the maintenance programming.
The CAL is in charge for the development of the experimental activity on a real actuator installed on a test bench. The experiments will lead the specimen to a complete failure also by means of overload operation conditions and suitable fault injection, like lubricant partial or complete revomal.
On the basis of the available measurements (currents, position) a Change Detection algorithm will be developed. The algorithm is designed to identify changes in the stochastic properties of one or more time-varying features computed using the physical measurements.
