Smart Aircraft in Emergency Situations (SMAES)
Date du début: 1 févr. 2011, Date de fin: 31 oct. 2014,
"Ditching analysis is requested for large transport aircraft by EASA. The respective requirements are specified under § ‘’CS 25.801 Ditching’’. They are primarily devoted to a minimisation of risks for immediate injuries and the provision of fair chances for an evacuation. A significant part of average air travel is over water and historically a planned or unplanned water-landing event occurs gros ...

Manipulation of Reynolds Stress for Separation Control and Drag Reduction (MARS)
Date du début: 1 oct. 2010, Date de fin: 31 mars 2014,
"Reynolds stress is the most important quantity affecting the mean flow as it is responsible for a major part of the momentum transfer in the wall bounded turbulent flow. It has a direct relevance to both skin friction and flow separation. Manipulation of the Reynolds stress can directly lead to changes in the viscous stress at the wall so as to effectively control the flow for effective flow cont ...

Weather hazards for aeronautics (WEZARD)
Date du début: 1 juil. 2011, Date de fin: 30 juin 2013,
"On April 14th, 2010, the eruption of the Eyjafjallajökull volcano and the accompanying cloud of volcanic ash forced most countries in northern Europe to shut their airspace, grounding more than 100,000 flights, affected an estimated 10 million travellers and had a financial impact of 5 bn US$ over a seven day period. This event revealed to what extent our society and economy rely on the availabi ...

Advanced Turbulence Simulation for Aerodynamic Application Challenges (ATAAC)
Date du début: 1 avr. 2009, Date de fin: 30 juin 2012,
"The ATAAC project aims at improvements to Computational Fluid Dynamics (CFD) methods for aerodynamic flows used in today’s aeronautical industry. The accuracy of these is limited by insufficient capabilities of the turbulence modelling / simulation approaches available, especially at the high Reynolds numbers typical of real-life flows. As LES will not be affordable for such flows in the next 4 d ...

Aerodynamic loads estimation at extremes of the flight envelope (ALEF)
Date du début: 1 mai 2009, Date de fin: 30 avr. 2012,
"ALEF's objective is to enable the European aeronautical industry to create complete aerodynamic models of their aircraft based on numerical simulation approaches within the respective development processes. I.e. ALEF will kick-off a paradigm shift from greater confidence in experimentally measured loads data to greater confidence in computational results. Beyond the scope of ALEF this paradigm sh ...
