Technical Regulations 2017 F1 Formula 1: keys and philosophy

  • In 2009 there was a radical change of rules that teams could undertake development more freely.
  • The introduction of new hybrid propellants in 2014 was not accompanied by significant changes aerodynamically.
  • Therefore, the magnitude of the challenge that Formula 1 teams will face in 2017 is unprecedented in so far this century.


Three to five seconds per lap. That is the goal that lawmakers seek to achieve with the introduction of the new regulation. Faster cornering, greater aesthetic aggressiveness and mainly greater emotional connection with fans.

Although there have also been changes in the sporting regulations and mainly concerning motors in the system tokens-, the new technical regulations of Formula 1 for the 2017 season has been thoroughly overhauled in order to reversing the trend of recent years that little by little, he has been leading to a lack of communion with the fans, who feel that cars are not fast, nor pretty, nor noisy.

Dictionary Formula 1: Parts of an F1 and tires

While this last point aims addressed in the future, the FIA ​​and Strategy Group who outlined the new regulations already in force, have attempted to improve the first two with a deep remodeling of the roadworthy to convert cars into something completely different.

Surely the most characteristic element are the new tires which have grown considerably but, when we know the appearance of new cars by the end of February, it is quite possible that the whole call our attention. Wider chassis, ailerons, diffuser ... everything grows in the new stage that Formula 1 must deal with limited resources. Not because of budget shortages, but by the limitations on the regulation provides test and simulation, either in the wind tunnel or through Computational Fluid Dynamics.

The tires

Between 25% in the case of the front-and 30% in the case of traseros-. So they have grown Pirelli tires to meet the challenge of keeping on the road to new cars.

Pirelli F1 2017

The front having passed 245 to 305 millimeters thick, while the rear increases to 80 mm width to stay in spectacular 405 mm. And, yes, the diameter of the rim remains unchanged in the now classic 13 inches.

suspensions

To alter the dimensions of the tires and the chassis, and the levels of downforce, the suspensions will also be redefined. In this regard there are two main constraints. On the one hand, the total width of the tire excluding monoplaza-, can not exceed 200 cm, while the angle of the suspension arms -used as an airfoil more- can not exceed 10 degrees with respect to the reference plane (the floor of the car).

Note also that the increase of tire size, which are an element of the suspension more in the case of monoplazas- and downforce forces engineers to redesign to be more resistant with a greater bearing capacity pressures with the considerable increase cornering speed.

front spoiler

This element is essential when establishing aerodynamic quality work that the different elements of the car performed. It is the first part that touches the air, then travel the body, both above, and below.

To help achieve the goal of improving three to five seconds per lap times Formula 1, has increased downforce front wing can generate. They have been modified, both the dimensions and design and have specified tolerances deformation.

The front wing, where it all begins

The overall length has grown from 1.650 meters to 1,800, thus allowing more work surface. In the central part, the so-called Y250 (250 mm on each side from the central axis of the car) which is not more than the central part that can not be generated downforce, remains the same, but modifies the shape of the plane principal, now It has an arrow to be obligatory an angle of 12.5 ° about the transverse axis.

Regarding the endplates and front wing boxes, regulations prevents puncture the tires to other cars, thus defining the thickness and shape of certain elements according to their position. Ending the bending test, the application and point loadings remains unchanged (1,000 Newtons), but now 15 mm tolerance allowed in place of the 10 2016. Thus, it is possible to generate more downforce. Similarly, the bending test of side flaps relaxes 2 millimeters, can now give a total of 5 to apply a load of 60 Newtons.

Car length and rear spoiler

As a result of the change in the dimensions of the rear spoiler, the car grows in what refers to length. From the axis of the rear wheels, now must be 71 centimeters to the far end of the wing, so the car grows 11 centimeters respect in relation to 2016. At the front, the measure set in the regulations is 1.20 meters.

As regards the rear wing, the philosophy changes completely, considerably lowering its height and widening to provide the car with much higher levels of downforce. At its base, the spoiler shall measure 84 centimeters, but from 25 centimeters above the diffuser, the width is increased up to 95 cm, the endplates thereby adopting a more sinuous and aggressive look.

Height, however, is reduced to 80 centimeters stay, Fifteen less than in 2016. In addition, the bottom of the main plane of the wing grows from 20 centimeters to 25, also increasing its aerodynamic influence.

Diffuser

Which possibly is the largest generator of downforce a car without therefore drag will be increased relevantly, also it grows to adapt to the new measures of the car, especially with the rear spoiler it means.

The diffuser: a vital aerodynamic element

Its width is increased by 25 mm on each side for a total of 1,050, but its height and so does nothing less than 50 mm for a total of 175. Further, its depth grows from 35 centimeters to 52.5, because now you are allowed to start 175 mm before the rear axle reference in 2016 marked the beginning.

These measures accord that element a much greater role in 2017 and, in conjunction with the new ground and ailerons, give the car an amount much higher downforce.

bargeboards and side deflectors or pontoons

minimize downforce levels to ensure that the cars were slower: with the regulatory change introduced in 2009, quite the opposite this year with attempted. To this end, considerably they limited the bargeboards. Although in recent years, these elements have evolved greatly from the hand of Mercedes, in 2017 they will take a significant role thanks to a more open development policy.

They may be larger to be able to start much closer to the front wheels -430 mm behind the axis of the wheels delanteras- They shall have a maximum height of 475 mm. In return, the front of the pontoons may not contain any element of the body and its outer edge to be delayed 15 ° to the transverse axis of the car. This last change is due simply to aesthetic issues with which aims to achieve a more aggressive look.

Vortex generators, what are they and how do they work?

Soil and Splitter

The dimensions of the floor of the car have changed to accommodate the larger car and make it so that this year we will see how the sides of the bottom protrude below the pontoons. Since this year, the floor will have a width of 1.600 meters (20 centimeters more than in 2016), thereby increasing the aerodynamic effect formed in conjunction with the pontoons and the splitter. Instead length lost 10 centimeters in front of the mentioned splitter. To compensate for this last point bending test of the previous appendix soil is delayed as far as position is concerned, remaining unalterable tolerance of 5 mm to apply 4000 Newtons of force.

What is Rake?

Cameras on board

Aesthetically, one of the most striking changes apart from those already mentioned, will be the new location of the television cameras, with respect to the nose, they can no longer be placed above the height of the body, because it reduces the minimum height and the maximum is reduced to create a regulatory section never exceeds the height of the nose structure. This, together with the reduction of only 1.5 centimeters supports, aerodynamically impossible to play with them.

Cameras placed at the top of the engine cover also have to follow a fixed pattern, unable to get his front in 2017 to less than 28 centimeters from the end of the cockpit.

Weight

As a result of the new dimensions, the car should in principle be 20 kilograms heavier in 2017, thus reaching 722 kg. This also influenced weight distribution, being the front axle of 328 kilograms and rear 387.

But the first week of February, the FIA ​​decided to increase up to 728 kilograms of fuel and pilot to compensate weight gain of the Pirelli tires. The front weigh 1kg this year. more than 2016, while the rear weigh 1.5 kg. more than the previous season.

Gear ratio

In 2014 it began to limit the indiscriminate change gear ratios of the gearbox, allowing a single change per season. But in 2015, this exception was removed and the teams moved to be forced to select a single gear ratio for the entire season regardless of the circuits in which it competed.

In 2017 you can again make a change, leaving the previous selection eliminated unless the gearbox in question is within the cycle of life six races to be met by regulation.

Brakes and fuel

One change which is a direct consequence of increased speed cornering, weight and dimensions of the cars, is the thickness of the brake discs, which It will take 28 to 32 millimeters.

regulations are also set on fuel. From this season, the fuel tank grow to 105 kg capacity (although the flow 100 kg / hour remain unchanged) and suppliers can only use five different specifications throughout the season, using only two of them during the same weekend Grand Prix.
