MARANELLO, 15 February – Ferrari has revealed in an article published in his Magazine that the nose of the step, which characterizes the new F2012, and most of which compete in F1 next season, has been studied to create a Venturi tube. «With fashion, sometimes made compulsory by the circumstances, as in the case of snow at Maranello, to present the car via the internet, the mystery on performance potential is still denser ", we read on the website of the House of Maranello, which published the Magazine. «Not to mention pre-season tests: the auto run with tricks of petrol due to load and unload, ailerons and other small are temporary, so as not to make people realize their true potential, fueling speculations and hopes. There is also who does the cunning, as it had been for Brown in 2009, arrived at the last moment as a Cinderella, just to keep hidden the famous trick of the double diffuser that went on to win the world title. This year will certainly funny: the step nose seems to have become the only real theme, but in reality, with substantially identical engines and strong constraints on the development of the car, the car will be all powerful. And there begins the beautiful: who or what will make that small difference which means win? The F2012 has searched. Between now and March 18 to try to understand if this strange muzzle which also has a Venturi Tube to function by direct air into the underbody, there will also become likeable. Indeed, very nice "reads in the article horse.
INCREASED speed – The idea suggested by Ferrari is the snout force air into a kind of virtual pipe that aims to increase the speed of the flow. The Venturi tube is a system used to accelerate the flow of a fluid, as can be the high-speed air, pushing him into a conical tube. In this narrowing the fluid is forced to increase its velocity reducing pressure and producing a partial vacuum, which for a Formula One means to stick it to the ground and increase adherence. This is the true secret weapon of red, in response to the speakers blown used last year from Red Bull and banned this year? We'll see in the next test, scheduled for next Tuesday.
