The fourth issue of Aerospace Lab, the Onera International Journal, is on line on www.aerospacelab-journal.org. It is devoted to the mastering of complexity. 

A first at Onera: the successful testing of an injector with a technology new in Europe - a double "Swirl" supplied with liquid oxygen /liquid methane. This technological progress was implemented on Onera’s cryogenic test bench Mascotte, located in Palaiseau (October 2011). 

ONERA'scientists have developed a synthetic turbulence generator to simulate the development of aircraft engine jets with greater accuracy. The results are presented in a video.

Manipulate a virtual helicopter model that has been used for an aerodynamic simulation, and examine it from every angle.

Onera has participated in a large scale ground vibration testing program on an A340-600 and has validated new means and methods suitable for large aircraft

Theoreticians and investigators in fundamental physics in space met for a conference at the Onera center in Palaiseau on Monday, September 19th. These specialists came to support the Microscope space mission and to emphasize how important it is for scientific knowledge. Microscope is a satellite (Cnes project) to confirm or invalidate the principle of equivalence, observed by Galileo, then by Newton, and which is the basis of the theory of general relativity of Einstein. The decision to launch Microscope in 2017 has been confirmed by the French space agency CNES in december 2011. 

The final report of the European project Swafea, on the feasibility and effects of introducing alternative fuels in aviation, is available. 

Thanks to the atmospheric turbulence correction system NAOS, developed under ONERA management, the discoveries of the VLT have been exceptional: planetary details of our solar system, the first images of an exoplanet, the revelation of a super massive black hole in our galaxy, etc.
