Enzo Ferrari asserted that the English manufacturers should not claim the title of builders in when they did everything in the house but bought the components from the best suppliers on the market using the name of garage owners. The old Drake also knew that with the mechanical changes you earn tenths but with the tires working well you can recover even the seconds. In any case, even a total manufacturer like Ferrari and Mercedes has to deal with some components that necessarily have to buy. The tires and rims on which calettano. The difference is also in choosing the best suppliers that offer the best material and the best possible technology.
All this to explain that it is the Mercedes but also the Redbull then used a special surface coating for the 'inside their circles. As seen in the photo to the left is a circle with a black Mercedes with fins and right to RedBull with a black jacket the same but with a series of small dimples. This coating was created by an Italian manufacturer the Nanoprom, and it is a paint based surface of a component called Polisyl. In practice it is it is a surface coating which protects the surfaces which wear out by atmospheric agents and also used on boats clearly improves the penetration in the water for reducing friction it is said that this paint is also used for the bodywork of the Redbull to improve the aerodynamic penetration.
Use this product on a circle by formula 1 It has the functions to stabilize and increase the flow of warm air from the brakes into the circle itself to the outside by straightening the turbulence in that area huge gift. A controlled flow inside the wheel also allows to keep under control the temperature of the magnesium wheel. Since magnesium is an excellent thermal conductor, the heat is transferred directly to the tires with all the damage that you know. It goes without saying that control the flow vortex can not also allow teams to have the circles in desired temperatures to make the circle as a kind of blanket inner race running as needed.
The thermal room photo, shows how the RedBull uses this protective coating and dimples to keep the internal temperature constant cornering removing faster hot air to the outside. As seen in the images above, a curve faced by Vettel in Austin to the temperature curve input is greater that in the final phase of the curve where it should be higher for the effort in curve. But the amazing thing is the use of this paint on the straights as seen in the lower part of the picture with tire warm even on the obverse. Combined with Lemelle and dimples air flow can be controlled in its elimination or stagnation. If you can control the flow velocity of the hot air from the brakes are held hot wheels even on the long straights. It is saying that if a circle remains warm even the rubber that remains above is kept hot and into the corner you have the ideal temperature while the other Ferrari in the lead coming into the curve on cold tires with a noticeable loss of grip and then warm too much not being able to control the temperature in the middle curve. Such a system as simple as it can also bring advantages in terms of lap time even of the order of eight tenths in certain tracked. In fact if we go back to the speech starting work with the tires Pirelli earns much more than any mechanical or aerodynamic devilry. The fact that this company is in the Nanoprom Emiliana land and its beneficial effects discovered them first in UK from companies like Mercedes and Red Bull, It speaks volumes about the fact that it makes no sense to build everything yourself then if you neglect certain details that make a huge difference.
