Latest end-of-season questions: technical tricks and originality
with F1, In the foreground / by Anna Re / the 17 November 2013 all 19:14 /
Penultimate test session at the Austin circuit: we will see who studied well, apart from that nerd Vettel. Promoted, postponed and rejected among the "students" in competition. Opposite is a winter of intense and restorative study ...
From today, only one weekend separates the Formula teams 1 from the bell at the end of the F1 World Championship 2013. The FIA for the winter holidays did not fail to "impose" the dictates according to which to develop the car 2014. According to the new regulation, the single-seater cannot be developed (inserting or removing new components) during the four test sessions to be carried out during the season, approved for the championship 2014. A restriction that has a direct consequence: the teams will have to present the car on the track with the new components already installed, without being able to evaluate improvements or comparisons between different configurations during the test sessions.
For this reason, several teams use the latest races of the 2013 as test sessions, without giving up the maximum performance of the car in the current race.
Red Bull hasn't made any aerodynamic changes, but experiment with Polysil on circles (amorphous solid similar to liquid glass, with black mattifying pigment, used to improve thermal conductivity) with the intent to speed up the heating of the rims and keep the heat distribution constant. Mercedes experiments with new paints, to study the effect on aerodynamic flows. Williams and Sauber have modified the exhausts thus obtaining amazing performances (Valtteri Bottas not, Nico Hülkenberg room), but without making substantial changes, but by proposing solutions from the 2012.
Lotus will race with both single-seaters suitable for the Texan track, but already changed in perspective 2014, with the long wheelbase (wheelbase longer than 10 centimeters), the configuration preferred by Roman Grosjean and with an open air vent near the upper attachment of the rear suspension. The Ferrari reads everywhere about "monkey seat", "Front wing with upper flap", "Bridge side deflector" (we wrote it too): only to pronounce them would one have to enroll in a university training course, with personal assistant ...
The Circuit of the Americas requires more downforce: this is the purpose of the monkey seat and makes his debut in the car from Maranello at the Bahrain GP 2012. It is a very small aerodynamic appendage installed on the lower support of the rear wing, with the aim of directing the heat by improving the interaction of hot air that goes from the hood to the rear wing. The monkey seat in the final part of free practice was eliminated from Alonso's F138.
The front wing is designed to generate aerodynamic load and also to manage the air flows to direct the flow along the body of the car and minimize resistance to forward movement, decreasing the amount of air that impacts on the tread. This is the purpose of the front wing: the one mounted on Massa's car is that of the Singapore GP, the front wing with two blowholes on the top was tested on the Alonso car (upper flap), a solution inspired by Red Bull.
Finally, the bridge side deflector - used only in Abu Dhabi - has the purpose of directing the flow of the sides towards the final part. Lift decreases thanks to the particular "P" structure that flattens the flow, obtaining greater adherence to the car body in the lateral area. Another effect is to stabilize the car in the event of side gusts.
A solution used in practice sessions, but then eliminated in both cars for qualifying. We will see how much the "Allison cure" in Ferrari - with its assemblies-and-disassembles - will be able to reinvigorate hopes for second place in the constructors' classification.
All that remains is to wait for the 20 for the exam session: all on the starting grid ready for questions! Ballots later 56 laps ...

Read MoreF.One – Tecnica, the Nanoprom launches Q.R.S for hoops!
After providing the all'OZ Racing Polysil, the silicon film formed by nanotechnology that allows to retain the heat of the circle with the goal of immediately send heat into the tires in the first lap of each stint (qualifying and race), the Nanoprom, company of Sassuolo, He has already designed an interesting evolution of the theme: il Quantum Radial System. So far the engineers have worked only in the outer face of the rim, but inside the channel, making sure that the heat generated from the brake to dissipate (the wheel comes to temperature peaks which reach the 200 degrees) avoiding that there is disposal quickest possible thanks to the special ducts. With the current Pirelli tires circle has taken a secondary function that Gp Gp after gaining increasing importance.
GLASS LIQUID The application is simple: spraying the "liquid glass" in the circle and creating a film of a few microns (touch does not feel any step between the treated and the "naked") that, in addition to ensuring a limited thermal conductivity, associates high abrasion resistance thanks to the surface hardness of this material which also offers a small aerodynamic advantage since it reduces the turbulence generated in the circle for the rotation of the wheel. Without forgetting that the traditional coating of a wheel F.1 requires at least 65 grams of paint, while it only takes Polysil 5 grams!
NANOPROM FORGE OF IDEAS Now the genius engineers to Sassuolo of Nanoprom directed by Gianluca Falleti studied a new treatment that is aimed at increasing the temperature on the inside of the circle: exclusive image that we propose, indeed, We see the Quantum Radial System that has been sprayed with the power to have a high thermal conductivity. The Opposite of Polysil! The tests carried out have shown a marked improvement of the "warm up" in the circle and consequently of rubber. Also in this case we have been used of nanotechnology (some people think that you are also materials for aerospace and military nature!) but without having as a starting silicon.
THERE 'S ONLY THE POLYSIL What is it? For now, the curiosity of Q.R.S. can not be satisfied, because the new material is still top secret, but are different teams of Formula 1 who have already shown a great interest in this innovation throughout Italian. What is the temperature rise that can be drawn from this treatment? The experiments are initiated with a gain of five degrees, but tests conducted later are leading to more meaningful values, especially since it would be possible to generate more heat when the designer needs it most.
MANUFACTURERS CONCERNED short, the feeling is that the Nanoprom not want to be a company that wants to limit to only offer revolutionary products, but also it has the ambition of becoming with its engineering consultant Manufacturers, to develop other applications that can provide performance benefits to the cars that represent the ultimate expression modern technological ...

Read MoreA 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.

By Julian Estevez – Tuesday, 19 November 2013 – UPDATED 06:08h.
Last year when I saw the first race of Austin I took a good feeling and I found a very entertaining race, something that did not happen this time. Last year the circuit debut and prevented new asphalt tire temperature cogiesen, which gave enough emotion. This year, the asphalt was already settled and could make a stop, and those races to a pit-stop usually boring. That's what happened with Bridgestone, which it made it very predictable and durable shoes. Pirelli has threatened that if the FIA does not allow training, them for the next season will show durable tires without. Watching the bats have received this season, no wonder, and it seems logical request. further, Pirelli now not develop gums with Formula 1 of this year, but it has an outdated model 2010, which further complicates design. As I read somewhere, the best combination is the one that was at the beginning of this season: very fast tires, but they degraded quickly. By the way, Women in sport have been used primarily as vases, not only here but they have not received equal treatment. Science and history also keep the place deserved for females, and there are many inventions and scientific developments carried out by women who have been forgotten. The first historical tribute of this column goes to Stephanie Kwolek, Polish-American scientist still alive who developed the famous kevlar, which it is used today in the Pirelli and flak jackets, among other applications. We continue with Pirelli, It is that this weekend has to speak the nth detail advantage over rivals Red Bull. Specifically, It has commented that the Austrian team employs polysil, a polymer applied on the tire rim improves heat transfer. It is one of computer keys: rapid heating in the first laps. It is polysil which it is a thin film silicon based also favors the turbulence generated in this area of the car. Anyway, he polysil It is the trade name of a company called Nanoprom, and is Italian, so it would not surprise me Ferrari and other teams also employ this product, and possibly it is being used before this year. And you can not forget that a great advantage is efficiency in pit-stops; this weekend again set a record by making the change wheels 1,9 seconds. Although primarily it is talking about a possible delay in the engine cylinders, but that I'll talk another day, Nor should we believe absolutely everything that appears online. This week has also given to local news, although not exactly positive. Joan Villadelprat has been convicted for the crime of concealment of assets, specifically for selling equipment Epsilon Euskadi to Epic Racing at a price much lower than during the previous two years before the bankruptcy filing. 900.000 euro fine and three years' disqualification. It is another pending trial for 22 November where he will study whether Catalan and his partner incurred criminal offenses. But I do not want so close local news, and here is the second column tribute. Pepe Díez died this month. Probably few people remember him, but it pioneered retransmissions of Formula 1 in TVE over the years 80, and an expert in technical knowledge and ability to transmit fans. Poor penetration of Formula 1 during that time and the difficulty to rescue audios you have been relegated to oblivion. Rest in peace.

By Steven De Groote on 22 Nov 2013, 12:29
Even though it’s been known for a while, recent thermal imagery has shown the true effects of rim coatings to manage tyre temperatures. The coatings were first photographed on Mercedes AMG’s Advanti wheels, featuring dimples on the inside of the rim as well (inset). Later on, Red Bull was confirmed to also use a similar treatment of their OZ Racing wheels, although in their case the inside of the wheels features grooves rather than dimples. Ferrari meanwhile are said to be coating their OZ Racing wheels as well. It was recently also found out that the black coating is actually Polysil, produced by Nanoprom near Sassuola, Italy. It is a solvent based product containing polymers of silicium, mainly designed to protect all sorts of materials against surface friction. The product is typically sprayed to create a film of only a few microns to reach hardnesses of up to 9H. This is achieved mainly by letting the product fill up tiny gaps in the imperfect wheel surface, creating a very smooth result that may also help to reduce turbulence within the wheel. Its black colour however is interesting for teams as that will help for the rim to absorb heat from the brakes into the Magnesium alloy wheel itself. As the rim itself has a very high thermal conductivity, the heat going into the metal is then spread rapidly throughout its entire body and partially transferred into the tyre through the tyre bead. As a result, it is possible for teams to keep the tyres at a more constant temperature, reducing the rapid drop of temperature of the tyres when running on long straights. Instead, with the rim properly warmed up, the tyre wall is kept warm, preventing the tyre’s thread to cool off too quickly. The net result is more grip at turn-in as the tyres haven’t cooled down as much as without the treatment. The thermal images in the inset show how this works brilliantly for Red Bull Racing. All three are shots from an onboard camera on Sebastian Vettel’s car at Circuit of the Americas during Q1 at the US Grand Prix. The first is taken on approach to turn 19, the second shows the turn-in point on turn 19, and the one below shows him at the end of the pit straight, before braking. It is evident that in all three images, the rim is relatively warm, and that by the end of the straight, the tyres are still lighting up across the entire thread’s width. Similar images from Mercedes AMG show similar, but less pronounced effects, while on the Ferrari the wheel was not marked as hot by the thermal camera, indicating a lower temperature than with the other teams. Even though it is still early days and nobody knows yet what will be the operating temperatures of the new ‘conservative’ Pirelli tyres, it is nonetheless very likely that this technology will continue to be used in 2014. Even more so, with Nanoprom citing the possibility to use their coatings on composites and aluminium, it is nearly sure that it is or will be used on parts of the engine as well.
