A special coating for wheels controls the temperature of the tires
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.

The Lotus paints Polysil inside the circles-Oz
The Lotus trying to get back on top of the Constructors': the team at Enstone is only eighth with just eight points in the bag and count in the second half of the season to make a turnaround to his disastrous season, heavily influenced by the power unit Renault.
In Hungary in circles of E22 It had been painted Polysil also in the inner part of thewheels Oz to improve the heat exchange with the Pirelli tires, widening the use which usually is limited the outside. In the image Nugnes are also visible sensors that detect the temperature of the rim and inside of the tires. The same solution will also be used at Spa-Francorchamps for the Belgian Grand Prix.

In the wheels of the FW37 is not only painting with black, but also a metal band
The Williams He wants to try to make up the ground on Ferrari in Bahrain and has brought some interesting solutions: in the picture Effe 1 Tech It is observed circle OZ of FW37 that, in addition to being coated by the black paint in nanostructured silicon that allows the transfer of heat by the brakes to the tires, keeping constant the correct temperature of use, shows end of vortex flow who substitute different serrations that we saw last year on several cars (Ferrari, Mercedes e Red Bull Racing). Vortex generators have a aerodynamic function for the best extraction of hot air and prevent the adhesion of rubber shavings Pirelli.

Read MoreEven the burner Vulcan B5 has a plus
The burner VULCAN B5, designed and marketed by Anchor Spa with highly innovative features for saving energy in the ovens, It has been further refined. The innovation, born from the collaboration with STILL NANOPROM, Sassuolo company supplier of advanced nanotechnology solutions for several teams in Formula One, It consists of a treatment that makes it even more performing the already outstanding performance of the reduction of the consumption VULCAN B5 AGAIN. Such treatment based on nanotechnology reduces to the maximum the surface roughness of the ferrous material, exponentially increasing the smoothness of the air / gas flows; decreases, also, the formation and deposition of any carbon residues. The end result is a mixing of air and gas and an optimal lengthening of the flame thus allowing greater penetration inside the oven. The evolution of the VULCAN B5 burner is one of the innovations being presented by Ancora Group at Tecnargilla 2014, held in Rimini from 22 al 26 September. The novelty has been made possible thanks to an exclusive partnership with Nanoprom, among the first in Italy to carry out research and development of nanopolymers. Ancora Group at Tecnargilla will be in Hall D1, stand 071

Read MoreThe new Polysil does not adhere to the rim murble
The Nanoprom adds another function to the third generation of the miraculous film silicon
The NANOPRO It launched Third generation of Polysil. The rims of the Formula 1 He is coming a new treatment that adds another important feature to those undertaken so far. It is like Gianluca Falleti, holder Nanoprom, and the consultant Gabriele Tredozi, former technical director at Minardi and HRT, They had adopted the philosophy that has made winning in Circus Adrian Newey, so each piece may have more functions to enhance the overall performance of the machine.
The Polysil has started talking two years ago when the OZ Racing began to be painted in black the inside of the rear wheels with a coating useful to retain the temperature that, instead, had been transferred to the tires thus allowing the rapid heating. The wheel, indeed, assimilating the heat (until 200 degrees) of the carbon discs and radiated tires Pirelli.
The Polysil is a film silicon formata da nanotechnology: spraying what is considered a “liquid glass” on the circle: the effectiveness is ensured by a layer of a few microns for the high surface hardness of this material which also ensures high abrasion resistance. The painting of a traditional wheel F1 cost about 65 grams, while Polysil fell around 5 grams.
Last year the treatment has been extended to the front wheels, while now in third generation of Polysil, the Nanoprom adds another very important property: It cancels the membership of murble, residues of hot rubber that are attached to the wheels. It has been calculated that avoids a significant weight gain during each stint (it comes up to 1 kg for the four wheels!), keeping surfaces clean, avoiding, then, which generate harmful turbulence which can have a negative influence on the trend of flows that now, especially with the perforated front hubs, have a role aerodynamic relevant.
