Future aero engines will need to be more efficient and contribute to the reduction on environmental impact of air transportation. They must reach some standards of performance by reducing emissions and creating some savings on operation costs.EIMG consortium has launched since several years some initiatives to develop future engines in the frame of the European Committee research programmes.Within different project such as DREAM, VITAL, NEWAC or LEMCOTEC, EIMG is ensuring the development of innovative technologies in order to further reduce the fuel burn, emissions and noise.In order to ensure the technological breakthrough, future aero-engines will have higher overall pressure ratios (OPR) to increase thermal efficiency and will have higher bypass ratios (BPR) to increase propulsive efficiency. These lead to smaller and hotter high pressure cores.As core engine technologies have been addressed in the previous project, E-BREAK project will ensure the mandatory evolution of sub-systems.It is indeed required for enabling integration of engine with new core technologies to develop adequate technologies for sub-systems. E-BREAK will aim to adapt sub-systems to new constraints of temperature and pressure.The overall picture of these initiatives bring all technology bricks to a TRL level ensuring the possibility to integrate them in a new aero engines generation before 2020.In its 2020 vision, ACARE aims to reduce by 50% per passenger kilometer CO2 emissions with an engine contribution targeting a decrease by 15 to 20% of the SFC. NOX emissions would have to be reduced by 80 % and efforts need to be made on other emissions.E-BREAK will be an enabler of the future UHOPR integrated engine development, completing efforts done in previous or in on-going Level 2 programs.
