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. The domain work programme develops through several phases: from the definition of requirements & architectures (phase 1), through the assessment of enabling technologies and subsequent application studies , up to the final demonstrations (phase 2 and 3) of selected solutions.
