Résumé des résultats (Abstract)

SILENCE(R) addresses the issue of aircraft noise, a major cause of concern around European airports, through three major objectives:
- Large scale validation of noise reduction technologies whose development was initiated by EU and National projects in '98;
- Assessment of the applicability of these technologies to current and future European products with minimum cost, weight or performance penalty;
- Determination of the associated achievable noise reduction, Novel concepts to be validated include low-noise fans, combustors and LP turbines, scared intakes, novel intake, bypass and hot-stream liners, nozzle jet noise suppressors, active control techniques and airframe noise reduction technologies.
Unless this technology can be developed and validated to reduce aircraft noise, traffic is likely to be limited by noise restrictions, affecting indirectly general economic growth. Expected results are consistent with the EC work program goal of 5dB reduction. The total partnership involves over 50 organisations from 14 EU countries, one candidate country and one associated state. Aircraft, aero-engine, nacelle manufacturers, as end-users, are the main partners in SILENCE(R).
