2 Long-term planning - Air transport 2050
The multidisciplinary task force was able to draw on the broad scope of research at Onera, which covers all disciplines in aeronautics and space. Share -
3 Graphene, a Material of Great Promise
Annick Loiseau reviews the research at Onera on this revolutionary material... Annick Loiseau, director of research at Onera, president of the International research group on Graphene & Nanotubes... What research is being done at Onera on graphene? -
4 Onera spin-off into the world optronics market
When he was an optics research engineer at Onera, Didier Rabaud had the opportunity to take part in the NAOS project for the Very Large Telescope in Chile... However, though we sometimes rely on the upstream research at Onera, the latter also comes to us for help with its research activities: when an activity turns out to be difficult to sustain in-house, then Onera outsources the work to us -
5 Combining lasers for powerful lidars
"This phasing system already existed for continuous laser beams", says Laurent Lombard, leading this research at Onera. "However, our lidars work with short laser pulses lasting 0 2 to 0 4 microseconds, a time during which light travels only a few hundred meters -
6 Onera Provides a Breakthrough in New Generation Aircraft Burner Operability
It was a case of improving the operability of a TAPS (Twin Annular Pre Swirl) type chamber injection system developed by Snecma, designed to reduce cruising flight NOx emissions by 50 to 60 %. Research engineers at ONERA had a double challenge: on one hand, combustion stability and quality when idling and, on other hand, reigniting the engine at high altitude -
7 Another World Premiere at ONERA: Photon Sorting
After creating the smallest cryogenic infrared camera in the world in late 2011, research engineers at ONERA reveal another world first: the sorting of photons by their wavelength, at a micrometric scale. This system revolutionizes the usual trade-offs between sensitivity and full color inherent to standard filtering, since this sorting technique allows all of the incident photons to be retrieved and used, while filtering" loses" photons -
8 Our nanotubes are right on track
"Before developing nanotechnology applications, we had to gain knowledge and know-how on these objects", says Brigitte Attal Trétout, research director at ONERA... "By studying the structure of the nanotubes under the electronic microscope, by analysing the temperature and the nature of the chemical species in situ at each stage of the process, and by developing numerical simulation tools, we have been able to understand how our nanotubes were formed", says Annick Loiseau, research director at ONERA -
9 A laser to measure noise
"By pointing the laser towards the zone that we want to study, we obtain information on the specific speed, that is to say, the speed of the vibrating air molecules, explains Frank Simon, research engineer at the ONERA in Toulouse. However, knowing the acoustic pressure isn't enough, we must combine these measurements with a model of the wave propagation in the air flow, that is to say, an aero-acoustic propagation model -
10 Nightglow - The light of the night
Also, as part of a REI (Exploratory Research And Innovation) initiative, Onera, together with the Observatory of Besançon and the DGA, has implemented a field campaign, aimed at characterizing the spectral, spatial and temporal variabilities of this radiation and at assessing their use for ground scene observation
