Adapting to the CFRP part production ramp-up" during which you can witness the interventions of aeronautical main groups (Airbus, Dassault), the calculationcode editors structures (ESI, SAMCEF) and ONERA. As a presenter at the session" Thermoplastics: tough materials, fast and robust production" organized by CETIM
Calculationcodes" revolutionized aerospace research. They would be instrumental in the success of the Airbus family, of the Rafale, and of the Ariane launcher, among others
The images show the micro-structures of these materials calculated by a finite element method using the ZéBuLoN structures calculationcode, developed by the Ecole des Mines in Paris in partnership with Onera... Finally, the ZéBuLoN software, which can perform non linear calculations, is one of the rare finite elements codes that can support the case of large multi-scale simulations, notably due to its unique multi-domain parallelism capabilities
"The fluid and mechanical structure calculations are already complex, and the same language isn't used in these fields, nor the same meshing (dividing space into small volumes, or elements) and it would thus be very complicated to create a new calculationcode integrating both branches of physics"
Behind the spectacular model of airflow around a wing, turbulence behind a plane, or complex movements of air around the blades of a rotor lie... 'calculationcodes '. These methods, based on software engineering, numerical analysis and physical modeling, enable complex calculations to be carried out
We are developing calculationcodes to foresee this. We must also create databases on the emissions of many elements, in order to be able to compare the terrain measurements with known emissions
This unsteady calculation was extended by a calculation of the noise radiation using an integral method (Kim code)... An acoustic use of this calculation was then carried out with the Kim code, and the radiated noise results were compared with the measurements made for Nasa by the University of Florida in its acoustic wind tunnel, again with very promising agreement
The proper operation of the aircraft requires calculation and communication times to be controlled... ONERA participated in the ADCN + project (new embedded communication architectures, with Airbus), is leading the Pegase project (improved network calculation performance guarantees, with Thales) and hosts the experimental network platform Demav
