First aerodynamic-aero-acoustic chaining created with an exchange surface crossed by a turbulent flow (“LES” CFD - “Euler” CAA).

On 2nd March 2011 Onera, with 5 other partners, signed the Flying Capabilities Campus convention, the aim of which is to create a center for research-training-industry open to the world of companies in the aeronautics and space sectors.

The Eole airborne demonstrator, the development of which is being coordinated by Onera, is part of the Perseus student program, Cnes being the contracting authority.

Modeling what happens in the combustion chamber as accurately as possible is very important in the design of more environmentally friendly aircraft engines. New "unsteady" models are now being used to better simulate the formation of pollutants as well as the ignition or extinction phases of these engines.

Are alternative fuels the way forward for the aviation industry? Are they technically and
economically viable? Are they acceptable from the standpoint of our environment and
society as a whole? What are the investment priorities for R&D and deployment? These
were just some of the main questions raised by the SWAFEA (Sustainable Way for
Alternative Fuel and Energy in Aviation) conference held in Toulouse on February 9-10,
2011. Financed by the European Commission, SWAFEA is a 26-month study involving 18
partners1 led by Onera, the French aerospace research center.

Le bruit aérodynamique généré par les systèmes hypersustentateurs1 et les trains d’atterrissages constitue la source prépondérante du bruit externe des avions civils gros-porteurs en phase d’approche. La prévision numérique de ce bruit représente donc un enjeu critique pour les constructeurs.

The applications are essentially in infrared optical metrology.

Space environment specialists have introduced innovations in the analysis of electrostatic discharge propagation on full-scale panels. 

A campaign for the spectral reflectance measurement of a salt lake in Central Anatolia was conducted in 2010. Many countries were involved.
