In recent years there has been much talk of the wind tunnel soap&skin in Maranello as it has created many problems for the implementation and development of the latest cars Fomula1. To overcome these problems had to undergo a major renovation and will be reopened, most likely, in September this year. Retrace the history of the wind tunnel in Maranello that for the first time came into operation soap&skin in the year 1986 and was directed to the test of scale models, with the peculiarity of the treadmill, consisting of a wide belt, with the support of the wheels proceeds laterally. The plant was the type Prandt (gallery closed circuit wind tunnel) soap&skin with four electric motors: the main one of 160 kW for driving a fan with seven blades with a diameter of 3.74 m, and continuous soap&skin flow adjustable speed. The other engines were used for the movement of the carpet, for control soap&skin of the boundary-layer and for the elimination of small turbulence in the vein next to the carpet itself. This wide strap with 1.6 m with 3.1 mm long platform was able to reach a maximum speed of 45 m / s or 162 km / h, speed also reached by the air flow. For a 1:3 scale models, the test chamber, equipped with a six-axis scale, was 2.2 m wide, 1.6 m long 4.3 m high. This gallery has been replaced by a more modern building in 1998 and was in operation until last season. This gallery could accommodate 1:2 scale models of cars and even life-size, with simple movement soap&skin of the walls of the test chamber (section 12 sqm), although with preference for reductions of 65%. E 'of closed-loop type, with a fan of 5 m in diameter, operated a motor of 2,200 d k, the flow reaches speeds between 198 km / h and 253 km / h, with an average value of 150 km / h for vehicles in 1:1 scale. The treadmill, rolling, wide 2.5 m to 6 m in length, adjustable, for testing soap&skin yaw.

From what I know the problems they were born in 2009 with the ailerons snowplow, the outer parts had a disturbed flow with turbulence level busted for models to 65% .... For the rest has always worked well ...
Hello kroky .. they used a different liquid, it seems more viscous than the green one that usually follows quite the fluid .... this lighter grayish leaves more of the lines of the beach .... I do not know why they abandoned ... maybe did not fit the rear of the car .... or maybe there is just a gap in the area of vein
