In Lille, a discreet location houses exceptional know-how serving aeronautics. The models from Onera, forged in the heart of its modernized workshops, embody French technological excellence. These creations, precious and high-precision, integrate advanced sensors and miniaturized engines, forming key components for the aerodynamic improvement of aircraft and missiles. True treasures often overlooked, they revitalize wind tunnel studies, enabling the exploration of new configurations for the aircraft of tomorrow.
The Onera, a prestigious aerospace research center, concentrates its design and manufacturing activity of models used in wind tunnel testing in Lille. These models, true technological marvels, are equipped with pressure and temperature sensors, as well as scales capable of measuring aerodynamic forces across six axes. Some prototypes even include small electric motors allowing the testing of complex aerodynamic configurations, essential to innovative projects like the combat aircraft concept Scaf under development at Dassault Aviation. These high-precision tools are highly sought after by major industrial players for their technical qualities and exceptional robustness.
the unknown models of onera
In Lille, the Onera has recently expanded its production capacity of aeronautical models, with an impressive extension of its workshop from 450 to 1,500 m². This center, a central player in French aeronautics, has stepped into the spotlight for the design and manufacturing of complex and technical models. The models from Onera, which were previously developed in Meudon, testify to their strategic importance in simulating air turbulence.
the technologies integrated into the models
The models from Onera are filled with invisible but crucial technologies. Imagine metal cylinders called scales that measure the torque of aerodynamic forces. These gadgets contain tiny sensors, precisely tracking pressure and temperature. Some even incorporate hidden electric motors just a few millimeters in size, allowing different aerodynamic configurations to be modeled during wind tunnel tests. A notable example is the Superman project from Onera, which will enhance the maneuverability of future concepts of combat aircraft.
the impact of models on the industry
These measurement tools are becoming indispensable. The models from the Onera have a precision that industrial players are eager to covet. They sometimes contain hundreds of sensors that help create stall maps and enhance aircraft performance. By combining a deep understanding of aerodynamic dynamics, these models pave the way for revolutionary innovations. Thanks to sites like Onera, researchers can explore the boundaries of what is possible.
