ONERA (Office national d'études et de recherches aérospatiales) is responsible for :
-to develop and guide research in the aerospace field
-design, produce and implement the resources needed to carry out this research
-to ensure, in liaison with the departments or organizations responsible for scientific and technical research, the national and international dissemination of the results of this research, to promote their use by the aerospace industry, and to facilitate their possible application outside the aerospace field.
O.N.E.R.A. has been based near Aussois for over half a century. As early as 1945, the large wind tunnel gradually took shape at the foot of the Aussois waterfalls. Their presence and power had in fact dictated the choice of the site when, as war damage, a wind tunnel that the Germans had begun to build in Ötztal, in the Austrian Tyrol, was transferred to French territory. The location was made possible by the development of the site: a railroad line, linked to Fort Saint-Gobain, was specially created to enable the construction of the wind tunnel, and the hydraulic energy potential that would supply the center was developed and reinforced by the impoundment of the Aussois dam in 1950 and the Mont-Cenis reserve in 1970. The project is finalized with the 4,000 tonnes of equipment transported by rail from Austria to Avrieux over a 6-month period. The first wind tunnel, S1 MA Paul Dumanois, was built in 1948 and went into service in 1952. Its 8-meter-diameter, 14-meter-long test section is still the world's largest continuous sonic wind tunnel at atmospheric pressure.
This structure, which can reach a maximum speed of 88 MW, draws its power from the penstocks of the Aussois and Mont-Cenis dams. The astonishing miracle of transforming water (10,000,000 m3/year) into compressed air also powers three other wind tunnels: S2, a pressurized, continuously operating subsonic, transonic and supersonic wind tunnel, commissioned in 1961; S3, a subsonic, transonic, supersonic and hypersonic gust wind tunnel, commissioned in 1959; S4, a hypersonic gust wind tunnel.
These facilities were supplemented in 1964 by three test benches powered by electric motors. The most powerful of these is capable of generating winds up to twelve times the speed of sound:
- S4B, an altitude chamber
- R4.3, a blade grating wind tunnel (1977)
- BD1 (1967) and BD2 (1975), hot and cold gas dynalpy benches.
