DEVILS - Sviluppo di sistemi intelligenti di lubrificazione dell'olio per motori VHBR di grandi dimensioni e sistemi di gestione del calore - nell'ambito del programma CleanSky2 (topic leader Rolls-Royce)

has the overall objective of validating a new concept of a variable flow lubrication system, through the design of a electronically controlled variable flow pumpwhich could become the focus of new lubrication systems for high-performance aircraft.

The project aims to achieve the following key objectives

• Reduce the amount of oil required for engine lubrication by up to 60 per cent, thereby reducing both oil consumption and the associated air pollution (currently the average oil consumption is around 0.3 l/h per engine). This can be achieved by introducing the innovative variable flow concept.
• Develop innovative error detection and monitoring solutions for the lubrication system. This will allow more accurate regulation of oil flow, temperature and pressure regulation and the implementation of the prognostic function, which will help reduce operating and maintenance costs (25%)
• Optimising the architecture of lubrication systems, taking into account the introduction of high-performance heat exchangers and reducing the complexity and mass of components, thus helping to reduce SFC and carbon dioxide (CO2) emissions.
