A group of European scientists, who usually have neither the financial resources nor the opportunity to use large wind tunnels, were able to install a largenumber of sensors inside the S1MA wind tunnel during a single experiment, in order to study turbulence and improve the fundamental physical understanding of the phenomena in this area
In 2010, Onera conducted a test campaign, a worldwide first of its kind, subjecting a full-scale space solar panel to a largenumber of electrostatic discharges. The experiment, conducted in an IABG structure in Germany, showed the propagation of discharges to the entire solar panel
The receiving site, located nearly 400 kilometers away, houses a largenumber of omnidirectional antennas. Based on the elementary signals picked up by these antennas, a narrow-lobe beam is produced
In September 1946, a largenumber of departments or institutions in charge of aeronautical research, scattered throughout France, were dissolved to be integrated to ONERA. Teams located in Paris, Neuilly, Chalais-Meudon, Palaiseau, Brétigny, Lille, Modane, Grenoble, Cannes, Toulouse and Alger-Maison-Blanche were concerned, in addition to various scientific detachments
The space is represented by a largenumber of sub-domains, or grids, partially overlapping", the mesh" of which are more or less fine. It is a computational case, called unsteady, as the main rotor and the tail rotor of the helicopter" are rotating" during the numerical simulation
