Through its leading partners and later formally as a network X-NOISE, then X2-NOISE, 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. As discussed in more detail in section B2, this has lead to the effective implementation of a number of complementary projects in the frame of a well coordinated technical strategy. Through FP4 and FP5 projects, the effort aiming at the EC short/mid term improvement of 5dB, also called “Generation 1 solutions”, is now well under way. Taking up on the elements provided by the ACARE SRA 1, X2-NOISE, as part of its activity, has identified gaps and priorities , considering through a common methodology the research to be carried out on each engine / nacelle / aircraft component of interest as well as generic enabling factors such as CAA techniques. As a result, a series of new projects aimed at Generation 2 solutions have been initiated. The Roadmap represents the projects involved in achieving the Generation 1 step as well as the early stages of the effort aimed the 2020 goals.
