Zonal Detached Eddy Simulation (ZDES) of the flow around a 3D wing of finite span in stalled configuration by the elsAsoftware... But in 2010 the Onera aerodynamicists performed a simulation of stall with the elsAsoftware using the computation resources of the GENCI (National High Performance Computing Facility)
In the framework of SHANEL, a joint Franco-German research project financed for Onera by the DPAC[ Aeronautic Civil Programs Agency,] specialists in aerodynamics at Onera used the in-house" software package elsA to calculate the blade-vortex interactions on a rotor[ rotor Bo 105] during descent flight
This development carried out with the elsAsoftware now allows jet development to be simulated with great accuracy. Work on jet turbulence modeling is of paramount importance because aircraft noise is mainly caused by turbulent jets, at the rear of the engines
With regard to the landing gear, the complexity of the three-dimensional geometries has for long time limited the application of these methods to realistic configurations because of the difficulty of generating the necessary meshes, particularly the multi-domain structured meshes5, the only ones compatible with the elsAsoftware
These calculations, accomplished with the ONERA elsA platform software, allow new design concepts and shape optimization of the various elements of the aircraft (the rotor blades in particular). Thanks to these tests and the CFD results, the global architecture of a civil tilt-rotor aircraft has been validated
