The EU technology programme ENOVAL (ENgine mOdule VALidators) can now be reached on the Internet at www.enoval.eu. The website offers comprehensive information on the project, its activities, objectives, technologies and partners and on the impact it has on aviation, environmental protection and the European Union and its citizens.
In this project, 35 European partners are jointly developing new technologies for the low- pressure system for medium-sized, large and very large turbofan aero engines - geared and non-geared. The aim is to achieve reductions in CO2 emissions of up to five percent and in noise of up to 1.3 decibels. “One focus of our activities is on testing the new components,” says ENOVAL coordinator Dr. Edgar Merkl of MTU Aero Engines. Plans are to conduct a total of 17 rig tests, in which the components are put through their paces in an engine environment.
Future engines for the next generation of short-, medium- and long-range commercial aircraft entering service from 2025 onwards will very likely employ ultra-high bypass ratios (12<BPR<20) and ultra-high overall pressure ratios (50<OPR<70), as investigated in the ENOVAL study engines. These engines are a key technology within the new Strategic Research and Innovation Agenda (SRIA) of the Advisory Council for Aviation Research and Innovation in Europe (ACARE).
