The DEVILS project ‘DEvelopment of VHBR engines Innovative Lubrication System’ is part of the Clean Sky 2 Program. The aim of the project is to develop a variable flow rate pump for the oil lubrication system of VHBR engines.


The DEVILS project has to fulfill four goals.

• Development of a model based systems engineering (MBSE) tool to aid the evaluation and selection of candidate VHBR system architectures.

• Development of methods and techniques required to achieve variable flows that will allow oil feed and scavenge systems to be optimized around the flight envelope.

• Demonstration of a variable flow intelligent oil system and advanced control scheme showing how operation can be optimized across a range of simulated flight conditions.

• Research into autonomous fault detection and correction for future Oil Systems.




On April 2018 DEVILS consortium achieved an important project milestone: the freezing of the oil lubrication system architecture and the geometry of the variable flow rate pump.

The current trend of developing aircraft engines that consume less fuel put a lot of pressure on the oil lubrication system cooling requirements due to higher speeds, loads, and temperatures in the engines. This is also true for Very High By-pass Engines due to the integration of high-power gearboxes and high-power starter-generators.
For this reason Engine manufacturers are looking for innovative design for oil lubrication systems implementing architectures that are able to meet the new cooling and lubricating requirements without impacting neither on the Engine weight nor on operational and maintenance costs.
The overall objective of project DEVILS Project is to develop an innovative variable flow rate oil pump to be integrated in a high performance aircraft lubrication system; the aim is to reduce both fuel and oil consumption.



The DEVILS Consortium comprises of the following partners; they all share a deep knowledge in the aerospace and hydraulic fields.

• Protom Group S.p.A (Project Coordinator)

• Abete S.r.l

• TAT Technologies Ltd

• Euro.Soft S.r.l

• Univeristà di Napoli ‘Federico II’

• Centro Nazionale delle Ricerche (CNR)

The DEVILS Consortium is willing to take advantage of this opportunity to bring on the market innovative technologies for Engine Oil Lubrication systems and validated model based simulation methodologies at a relatively low cost. In fact, It aims at becoming one of the European supply chain reference for the VHBR Engine community.
