That means that, theoretically, at high speeds, they could drive on the upside-down the surface of a suitable structure; e.

The use of aerodynamics to increase the cars' grip was pioneered in Formula One in the season by Lotus , Ferrari and Brabham. At first, Lotus introduced modest front wings and a spoiler on Graham Hill's Lotus 49 B at the Monaco Grand Prix , then Brabham and Ferrari went one better at the Belgian Grand Prix with full-width wings mounted on struts high above the driver.

Early experiments with movable wings and high mountings led to some spectacular accidents, and for the season, regulations were introduced to limit the size and location of wings.

Having evolved over time, similar rules are still used today. In the late s, Jim Hall of Chaparral, first introduced " ground effect " downforce to auto racing.

In the mids, Lotus engineers found out that the entire car could be made to act like a giant wing by the creation of an airfoil surface on its underside which would cause air moving relative to the car to push it to the road.

Applying another idea of Jim Hall's from his Chaparral 2J sports racer, Gordon Murray designed the Brabham BT46B , which used a separately-powered fan system to extract air from the skirted area under the car, creating enormous downforce.

After technical challenges from other teams, it was withdrawn after a single race. Rule changes then followed to limit the benefits of 'ground effects' — firstly a ban on the skirts used to contain the low-pressure area, later a requirement for a 'stepped floor'.

Despite the full-sized wind tunnels and vast computing power used by the aerodynamic departments of most teams, the fundamental principles of Formula One aerodynamics still apply: to create the maximum amount of downforce for the minimal amount of drag.

The primary wings mounted on the front and rear are fitted with different profiles depending on the downforce requirements of a particular track.

Tight, slow circuits like Monaco require very aggressive wing profiles — cars run two separate 'blades' of 'elements' on the rear wings two is the maximum permitted.

In contrast, high-speed circuits like Monza see the cars stripped of as much wing as possible, to reduce drag and increase speed on the long straights.

Every single surface of a modern Formula One car, from the shape of the suspension links to that of the driver's helmet — has its aerodynamic effects considered.

Disrupted air, where the flow 'separates' from the body, creates turbulence which creates drag — which slows the car down.

Almost as much effort has been spent reducing drag as increasing downforce — from the vertical end-plates fitted to wings to prevent vortices forming to the diffuser plates mounted low at the back, which helps to re-equalise pressure of the faster-flowing air that has passed under the car and would otherwise create a low-pressure 'balloon' dragging at the back.

Despite this, designers can't make their cars too 'slippery', as a good supply of airflow has to be ensured to help dissipate the vast amounts of heat produced by the engine and brakes.

In recent years, most Formula One teams have tried to emulate Ferrari's 'narrow waist' design, where the rear of the car is made as narrow and low as possible.

This reduces drag and maximises the amount of air available to the rear wing. The 'barge boards' fitted to the sides of cars have also helped to shape the flow of the air and minimise the amount of turbulence.

Revised regulations introduced in forced the aerodynamicists to be even more ingenious. In a bid to cut speeds, the FIA reduced downforce by raising the front wing, bringing the rear wing forward, and modifying the rear diffuser profile.

The designers quickly regained much of this loss, with a variety of intricate and novel solutions such as the 'horn' winglets first seen on the McLaren MP Most of those innovations were effectively outlawed under even more stringent aero regulations imposed by the FIA for The changes were designed to promote overtaking by making it easier for a car to closely follow another.

The new rules took the cars into another new era, with lower and wider front wings, taller and narrower rear wings, and generally much 'cleaner' bodywork.

Perhaps the most interesting change, however, was the introduction of 'moveable aerodynamics', with the driver able to make limited adjustments to the front wing from the cockpit during a race.

This too allows drivers to make adjustments, but the system's availability is electronically governed — originally it could be used at any time in practice and qualifying unless a driver is on wet-weather tyres , but during the race, it could only be activated when a driver is less than one second behind another car at pre-determined points on the track.

From DRS is available only at the pre-determined points during all sessions. The system is then deactivated once the driver brakes. However, this also reduces downforce so it is normally used on long straight track sections or sections which do not require high downforce.

The system was introduced to promote more overtaking and is often the reason for overtaking on straights or at the end of straights where overtaking is encouraged in the following corner s.

However, the reception of the DRS system has differed among drivers, fans, and specialists. Returning Formula 1 driver Robert Kubica has been quoted of saying he "has not seen any overtaking moves in Formula 1 for two years", [ citation needed ] suggesting that the DRS is an unnatural way to pass cars on the track as it does not actually require driver skill to successfully overtake a competitor, therefore, it would not be overtaking.

Early designs linked wings directly to the suspension, but several accidents led to rules stating that wings must be fixed rigidly to the chassis.

The cars' aerodynamics are designed to provide maximum downforce with a minimum of drag ; every part of the bodywork is designed with this aim in mind.

Like most open-wheel cars they feature large front and rear aerofoils , but they are far more developed than American open-wheel racers, which depend more on suspension tuning; for instance, the nose is raised above the centre of the front aerofoil, allowing its entire width to provide downforce.

The front and rear wings are highly sculpted and extremely fine 'tuned', along with the rest of the body such as the turning vanes beneath the nose, bargeboards , sidepods, underbody, and the rear diffuser.

They also feature aerodynamic appendages that direct the airflow. The bargeboards, in particular, are designed, shaped, configured, adjusted, and positioned not to create downforce directly, as with a conventional wing or underbody venturi, but to create vortices from the air spillage at their edges.

The use of vortices is a significant feature of the latest breeds of F1 cars. Since a vortex is a rotating fluid that creates a low-pressure zone at its centre, creating vortices lowers the overall local pressure of the air.

Since low pressure is what is desired under the car, as it allows normal atmospheric pressure to press the car down from the top; by creating vortices, downforce can be augmented while still staying within the rules prohibiting ground effects.

The F1 cars for the season came under much questioning due to the design of the rear diffusers of the Williams, Toyota and the Brawn GP cars raced by Jenson Button and Rubens Barrichello, dubbed double diffusers.

Appeals from many of the teams were heard by the FIA, which met in Paris, before the Chinese Grand Prix , and the use of such diffusers was declared as legal.

Brawn GP boss Ross Brawn claimed the double diffuser design as "an innovative approach of an existing idea". These were subsequently banned for the season.

Another controversy of the and '11 seasons was the front wing of the Red Bull cars. Several teams protested claiming the wing was breaking regulations.

Footage from high-speed sections of circuits showed the Red Bull front wing bending on the outsides subsequently creating greater downforce.

Tests were held on the Red Bull front wing and the FIA could find no way that the wing was breaking any regulation. Since the start of the season, cars have been allowed to run with an adjustable rear wing, more commonly known as DRS drag reduction system , a system to combat the problem of turbulent air when overtaking.

On the straights of a track, drivers can deploy DRS, which opens the rear wing, reduces the drag of the car, allowing it to move faster. As soon as the driver touches the brake, the rear wing shuts again.

In free practice and qualifying, a driver may use it whenever he wishes to, but in the race, it can only be used if the driver is 1 second, or less, behind another driver at the DRS detection zone on the race track, at which point it can be activated in the activation zone until the driver brakes.

Nose boxes are hollow structures made of carbon fibers. They absorb the shock at the time of crash preventing injury to the driver.

Just behind the driver's cockpit is a structure called the Air Box. The AirBox serves two purposes. It receives the high speed moving air and supplies to the intake manifold of the engine.

This high-speed air is pressurised and hence is compressed due to the Ram Effect. This high-pressure air, when supplied to the engine, boosts its power considerably.

Also, the air supplied to it is highly turbulent since it passes above the driver's helmet. The airbox absorbs this turbulent air, preventing it from disturbing the laminar airflow along with other parts.

The second advantage of the air box is its large size, which provides a large space for advertising, in turn, providing opportunities for additional ad revenue.

F1 regulations heavily limit the use of ground effect aerodynamics which are a highly efficient means of creating downforce with a small drag penalty.

The underside of the vehicle, the undertray, must be flat between the axles. A substantial amount of downforce is provided by using a rear diffuser which rises from the undertray at the rear axle to the actual rear of the bodywork.

The limitations on ground effects, limited size of the wings requiring use at high angles of attack to create sufficient downforce , and vortices created by open wheels lead to a high aerodynamic drag coefficient about 1 according to Minardi 's technical director Gabriele Tredozi ; [28] compare with the average modern saloon car , which has a C d value between 0.

However, this drag is more than compensated for by the ability to corner at extremely high speed. The aerodynamics are adjusted for each track; with a low drag configuration for tracks where high speed is more important like Autodromo Nazionale Monza , and a high traction configuration for tracks where cornering is more important, like the Circuit de Monaco.

With the regulations, the FIA rid F1 cars of small winglets and other parts of the car minus the front and rear wing used to manipulate the airflow of the car in order to decrease drag and increase downforce.

As it is now, the front wing is shaped specifically to push air towards all the winglets and bargeboards so that the airflow is smooth.

Should these be removed, various parts of the car will cause great drag when the front wing is unable to shape the air past the body of the car.

The driver has the ability to fine-tune many elements of the race car from within the machine using the steering wheel. The wheel can be used to change gears, apply rev.

Data such as engine rpm, lap times, speed, and gear are displayed on an LCD screen. The wheel hub will also incorporate gear change paddles and a row of LED shift lights.

In the season, certain teams such as Mercedes have chosen to use larger LCDs on their wheels which allow the driver to see additional information such as fuel flow and torque delivery.

They are also more customizable owing to the possibility of using much different software. The fuel used in F1 cars is fairly similar to ordinary premium petrol , albeit with a far more tightly controlled mix.

Formula One fuel would fall under high octane premium road fuel with octane thresholds of 95 to F1 Blends are tuned for maximum performance in given weather conditions or different circuits.

During the period when teams were limited to a specific volume of fuel during a race, exotic high-density fuel blends were used which were actually more dense than water, since the energy content of a fuel depends on its mass density.
