High-Speed Experimental Fly Vehicles - International (HEXAFLY-INT)
Date du début: 1 avr. 2014, Date de fin: 31 mars 2019,
The HEXAFLY-INT project aims to flight test an experimental vehicle above Mach 7 to verify its potential for a high aerodynamic efficiency during a free-flight while guaranteeing a large internal volume. The feasibility for a 3m long vehicle was demonstrated during the European L0 precursor project HEXAFLY. Its realization will now be enabled on an international scale underlining the need for glob ...

JEt noise of high bypass RatiO eNgine: Installation, advanced Modelling and mitigatiOn (JERONIMO)
Date du début: 1 nov. 2012, Date de fin: 31 août 2017,
The central goal of JERONIMO is the understanding of the physical mechanisms of ultrahigh bypass ratio (UHBR) engines with a bypass ratio (BPR) larger than 12 and the related installed jet noise with potential jet-wing interaction. The aim is to reduce uncertainties in jet noise characterisation of this novel installation configuration by wind tunnel tests and predictions and being able to derive ...

Grey Area Mitigation for Hybrid RANS-LES Methods (Go4Hybrid)
Date du début: 1 oct. 2013, Date de fin: 30 sept. 2015,
The aeronautical industry lacks confidence in the accuracy of computational fluid dynamics (CFD) in areas of highly non-linear, unsteady flows close to the flight envelope borders, which demands advanced approaches and methods. The family of Hybrid RANS-LES Methods (HRLM) is the best candidate for the next generation of CFD methods for increased fidelity at industrially-feasible expense. While HRL ...

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 ...
