The ENOVAL project will provide the next step of engine technologies to achieve and surpass the ACARE 2020 goals on the way towards Flight path 2050. ENOVAL completes the European 7th Framework Programme (FP7) roadmap of Level 2 aero engine projects. ENOVAL will focus on the low pressure system of ultra-high by-pass ratio propulsion systems (12 < BPR < 20) in conjunction with ultra-high overall pressure ratio (50 < OPR < 70) to provide significant reductions in CO2 emissions in terms of fuel burn (-3% to -5%) and engine noise (-1.3 ENPdB). ENOVAL will focus on ducted geared and non-geared turbofan engines, which are amongst the best candidates for the next generation of short/medium range and long range commercial aircraft applications with an entry into service date of 2025 onward. The expected fan diameter increase of 20 to 35% (vs. year 2000 reference engine) is significant and can be accommodated within the limits of a conventional aircraft configuration. It is in line with the roadmap of the Strategic Research and Innovation Agenda for 2020 to have the technologies ready for “Optimized conventional aircraft and engines using best fuel efficiency and noise control technologies”, where UHBR propulsion systems are expressively named as a key technology. ENOVAL will be established in a consistent series of Level 2 projects in conjunction with LEMCOTEC for core engine technologies, E-BREAK for system technologies for enabling ultra-high OPR engines, and OPENAIR for noise reduction technologies. Finally, ENOVAL will prepare the way towards maturing the technology and preparing industrialization in coordination with past and existing aero-engine initiatives in Europe at FP7 and national levels.
