Abstract
The Clean Sky is one of the Joint Technology Initiatives (JTI) launched by the EC in the FP8. It represent the most ambitious research program in Europe (approximate value: 1.6 B€) aiming at the greening of Aeronautics and Air Transport; 30-40% reduction of CO2 and NOX emissions and the halving of perceived noise around airports are both pursued through the integration of advanced technologies; validation of results is expected to be achieved in a multidisciplinary approach leading to full-scale ground and flight demonstrators. Technologies allowing for such step change are organized into six main themes, six Integrated Technology Demonstrators (ITD), that cover the broad range of R&T work. A "technological evaluator" - a set of models to predict the local and global ecological impact of the technologies being integrated - will allow independent analysis of the projects results as they unfold. The “Low Noise Configuration” project within the GRA ITD is pursuing a dual purpose: to assess technologies aimed at reducing airframe noise which during approach and landing phases (with engine power at minimum, high-lift devices deployed and undercarriage lowered) is a major contributor to the aircraft annoyance perceived by the resident population; to address technology innovation toward other paramount functions for a next generation, green regional aircraft: highly-efficient aerodynamics, including a Natural Laminar Flow (NLF) wing concept, to reduce fuel consumption and pollution at cruise condition; wing loading control to enhance aerodynamic efficiency in all flight conditions and, hence, to reduce fuel consumption and pollution over the whole mission also allowing for steeper initial climb, noise-abatement flight trajectories; wing loading alleviation to avoid any possible loads exceeding over structural design conditions and, hence, to optimize the wing structural design for weight savings.
