Experimentalresults showed the resistance of the structures created to the high temperatures of the hypersonic flights envisaged. This spectacular success was crowned by the awarding of the MBDA Innovation Prize to the Onera research team
The development engineer is required to accurately compare the software results with experimentalresults, in a generic configuration corresponding to its field of use. In practice, there are a large number of configurations, called test cases, which present experimentalresults in the form of a database, as well as a detailed description of the experimental conditions (geometry, physics, etc.)
"In a conventional internal combustion engine, whether automobile or aeronautic, the fuel is injected as a mist of droplets into the combustion chamber where, by the effect of heat, these drops evaporate and the vapor created is mixed with air before igniting" explains Fréderic Grisch, researcher of the Measurement Physics department and Onera-side coordinator of the CNRS-Onera aerospace federating project" Experimental and analytic methods for multi-component mists"
Result of a finite elements numerical simulation (ZéBuLoN code) showing the field of plastic deformations in a micro-structure of a composite material with a metal matrix... A simulation, like those the results of which can be seen above, gives" the micro" stresses, using the local behavior law...
