Zoom in the Lab
48 - A laser to measure noise
A new laser measurement technique makes it possible to locate and characterize the noise at a distance. This is of great interest for aeronautical acoustics!
47 - Lunar Radar Control
The soil, or even the subsoil, of the Moon can be studied… without leaving the Earth! This is indeed what ONERA’s Nostradamus radar can do, if its electromagnetic sight is pointed towards the Moon rather than towards the horizon.
46 - More realistic virtual engines
A very important step 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.
45 - The ice hunt starts here
A better understanding of the formation of ice on aircraft, helping the aircraft builders to prove that their aircraft can cope, and eliminating the most dangerous ice: these are the objectives of Sunset, a joint research project between Onera and Nasa.
44 - Maxwell would have loved it
EMIR is a system used to map electromagnetic fields using infra-red. James Maxwell, the founder of electromagnetism, would surely have loved it...
43 - The droplet and the engine
And what if we could reduce the consumption of aeronautic engines by controlling the evaporation of micro-droplets of kerosene?
42 - 50 years of laser research at Onera
Since its invention in 1960, applications of the laser have multiplied constantly. Research in aeronautics hasn't been left out, and lasers are now an essential tool for studying and understanding turbulence, analyzing combustion and observing pollution. A short tour around laser research at Onera.
41 - Drones in the playground with their big brothers
If we don't want to drones to be restricted to just a few reserved sectors of air space we have to show that they can be introduced with zero risk into the airspace occupied by piloted aircraft.
40 - Assisting combustion with plasma
Plasmas can initiate and accelerate combustion in engines and turbines. Their experimental study on test benches aims to improve the understanding of the involved phenomenon and to optimize it.
39 - Take-off at the Martel test bench
To reproduce the shock wave of a launcher on take off, the University of Poitier's Martel* test bench is being adapted for the generation of acoustic transient phenomena.
38 - Wind turbines, computers in the fields
Onera researchers are working on the behaviour of wind turbines. Objective: to improve their performances in all wind speeds and also to build even more powerful wind turbines. The solution may lie in more flexible blades.
37 - Time reversal - Time-Reversed Electromagnetics
To perfect electromagnetic compatibility tests, Onera researchers have adapted a technique developed over the last few years in acoustics, time reversal.
36 - Combining scale models for the best... in the best way
Play with complementarity of the models to simulate turbulence for increasingly complex phenomena.
35 - "Two in one" calculations - Coupling fluid and solid codes
ONERA is developing models linking fluid mechanics and solid mechanics.
34 - Ceramics are still surprising us - Eutectics
The latest generations of "eutectic" ceramics are very promising for engines...
33 - The second youth of optics - Nanophotonics
When trying to miniaturize optical instruments to the utmost, the physical phenomena that come into play become complex, fascinating and particularly interesting.
32 - Air streams on the water - Navy ship's aerology
Before launch, the French navy's ships are tested in wind tunnels to define their conditions of use.
31 - Drones become intelligent
The ReSSAC project's helicopter drone, a tool for real time experimentation and demonstration of autonomous decision making capabilities.
29 - Micro-turbines, maxi-difficulties
Miniature energy sources for miniature drones
28 - The lights of night - Infrared detectors
Several technologies of infrared detectors coexist to cover all uses.
22 - Is there a pilot on board the plane?
Researchers at ONERA are thinking about what an air transport system with no pilot and with no controller would be like.
21 - Quiet, you old crates! - Propellers
Onera is developing a propeller designed to reduce the noise from light aircraft without sacrificing performance or safety.
13 - Einstein and the accelerometer
Which instrument is able to measure data for climatology, analyze the forces exercised on an orbiting satellite and test Einstein's theories of relativity? It is called an accelerometer, a tool developed more than twenty years ago, and which today is capable of an incredible degree of accuracy.
07 - Prevention using drones - Civil surveillance
Civil drones for prevention of forest fires and identify firesetters.
