Since 1995, through the early work of the Aeronautics Task Force on “The Environmentally Friendly Aircraft” and the subsequent work carried in ACARE for the SRA1 and now SRA2, there has been a definite will to develop a consistent research strategy aimed at addressing Aviation Environmental issues on a problem-solving basis.
Within this context, the X-NOISE network has been involved in supporting the development of Strategic Research Agendas in the noise area as well as identifying the key topics and priorities governing their application. This has lead to the effective implementation of a number of complementary projects in the frame of a well coordinated technical strategy.
All through FP4 and FP5, an initial Phase 1 effort (see Roadmap 1) targetting the EC short/mid term improvement goal of 5dB aimed at bringing a number of noise reduction technologies called “Generation 1 solutions” to validation status (also called Technology Readiness Level 6). This effort was completed at the end of the SILENCE(R) project in 2007, demonstrating that with contribution from novel noise abatement procedures (investigated in parallel projects) the interim noise reduction goal was to be met.
Phase 2, initiated as early as 2002 in enabling areas, is now well under way, addressing a wider range of solutions aimed at fully achieving the ACARE 2020 targets (see Roadmap 2). As key solutions, promising novel aircraft / engine architectures and “Generation 2” noise reduction technologies will need to be investigated in a continuous effort over FP6, FP7 and FP8 to deliver the expected benefits.
In parallel as an indication of the wider range of expertise also mobilised through the nextwork, a significant and coordinated effort has been launched to improve the understanding of psychoacoustic factors as well as provide aviation stakeholders and policy makers with better tools and knowledge to help manage the environmental impact of air transport operations.
Looking further into the future, X-NOISE will also contribute to the developement of the new 2050 vision and research agenda coordinated by ACARE
