This is a research and development project in the 6. Framework Program of the European Union. The project proposes the development of an optimised maintenance concept for aviation hydraulic fluids based on an autonomous onboard system capable of monitoring fluid condition and restoring it when required, thereby increasing the lifetime of the fluid and preventing damage caused by degraded fluid. Lufthansa Technik Budapest is member of the Consortium formed by 13 Companies and Institutions who took the challenge of development of such system.
