The experimental station was located on the D148, at the time called« Route de Courville » (now« Robinette Road »), between Nogent-le-Roi and the place called « The Place ». It was about 2 kilometers from the city center shortly after the Industrial Zone of Sorettes and the diversion built since then.

The substation SNCF of Maintenon which absorbed the production of the wind, is located somewhere along the D983 in the bottom right of the map.

This black and white postcard from « Lapie » (above), gives an overview of the field. In the background is the hamlet of Vaubrun. In the foreground the south winch and in front of it, laid on sleepers, the pulley system used during the maneuver.

The tripod rested on three pillars: one concrete pillar (100 tons) for anchoring the wind turbine where it could be unlocked for the tilting and the two massive pillars supporting the axes of rotation during the maneuver (150 tons each). In the background, the research station, in white, housed offices, measuring instruments and a small workshop.

Perpendicular to the laboratory, a shed used for storage. There was a 1/15th scale model of the tripod (about 1 meter high) that made ​​me dream as it was so lifelike. I would gladly have accepted as a Christmas present. No one knows what became of it. It may have been scrapped with the rest. It is also possible that someone has inherited without having the slightest idea what it is and it lies dormant somewhere.

One can see all around the field, 8 towers of 31 meters equipped with BEST-Romani anemometers and a 60 meters pylon topped with the windsock used to refine the orientation of the wind turbine. These pylons were arranged in a circle at a sufficient distance from the turbine so that their anemometers might not be disturbed by the movements of the propeller.

One can guess along the path to the winch, the hut (dark) which housed the station manager when tilting . This picture has been taken the wind turbine halted as evidenced by its orientation relative to the wind direction indicated by the windsock at the top of tower 60 meters (operating, the propeller would have been turned in the opposite direction) .

The small white building that is seen in the angle of the field in the bottom right next to the logo "Lapie", hosted the lavatories.

The pictures of the tilting of the wind turbine were taken from the other side of the fence of the terrain, in the field right on the photo in the axis « north feet - hut of command ».

The colorized picture (above) was taken by the photographer of « Lapie » the same day than the previous one. One can see on the far right, along the ground, the south winch. In the foreground, then left, the concrete pylons of the maillechort resistance line that served as electric emergency brake in case of runaway.

On the right, behind the last pylon of this line, one sees, laid near the ground, the fourth blade that was used in the laboratory for testing resistance to constraints.

In the background, left to the entrance of the station, one can see the line of 15,000 volts (on wooden pylons) used drive the resulting output to the SNCF sub-station of Maintenon and to the city of Nogent -le-Roi.

On this press photo, taken from the upper platform of the tripod, one can see the layout in "Y" which allowed access to the nacelle and blades when the wind turbine was tilted.

Perpendicular to the hangar that is seen in the background, the research station and in front, the two branches of the "Y" scaffolding tube type "Entrepose" connected to the station by a hexagonal structure pierced of a hole for receiving the nose of the propeller. The roof of the station and the two branches of the "Y" formed an angle of 120 degrees.

In front of the photograph is the shelter of the north winch (from where the cable of the tackle block was hooked to the top of the tripod) and IPN support for supporting the wind turbine when it was tilted.
