During takeoff and landing, the flaps (on the back of the wing) extend downward from the trailing edge of the wings. This effectively alters the shape of the wing, allowing it to divert more air, and thus create more lift. The alteration also increases drag, which helps a landing airplane slow down (but necessitates more thrust during takeoff). The wing flaps on either side of the nose cone are asymmetrical. They reduces in height nearer to the nose cone as this allows air to flow into the radiators and to the underfloor. If the wing flap maintained it's height right to the nose cone, the radiators would receive less airflow and therefore the engine temperature would rise.
The front wing of a Formula 1 car is without doubt the most complex aerodynamic device in race car design.Its main function is to generate downforce and will typically contribute towards 25-40% (depending on car setup) of overall downforce levels.
Since the aerodynamic downforce can exceed five times the weight of the car, the front wing alone has the potential to generate enough downforce equivalent to twice the weight of the car! Therefore, not only must the front wing function as an aerodynamic device, it must also be able to withstand the incredible structural loads. During high speed braking for example, the force equivalent to the weight of the car can be hanging from each of the two small front wing pillars.The above image highlights the individual components and typical naming convention of a Formula 1 front wing.- Fixed slots- gaps located at the leading edge of the wing that allow air to flow from below the wing to the upper surface Slats - Moveable leading edge sections used to form automatic slots. when the slats deploy, it opens the slots.
- Flat, rather high-aspect-ratio wings lacking slots, and with feathers at the base that streamline the trailing edge in with the body, are found in falcons, swallows, plovers, and other specialists in high-speed flight. In contrast, hawks that soar in open country have lower-aspect-ratio wings; and Sharp-shinned Hawks that hunt in woodlands (and.
Typically when aerodynamic gains are found elsewhere on the car, a front wing adjustment has to be made in order to redistribute the downforce levels to the desired aero balance.
An image showing the flow structures generated by the front wing and how they propagate downstream under the car.The other major role that the front wing serves is to manipulate the flow to the rest of the car. A vast array of intricate aerodynamic elements have been precisely arranged to direct the flow around the front wheels and control the wheel wakes downstream. The intention is to maximise the quality of flow to the underfloor and diffuser. The increasing complexity of the front wing is a result of the compromise between front and rear downforce generation. Generate too much front downforce and you compromise the ability for the rear to do the same.Generate too little front loading and the overall downforce level will be reduced (as rear downforce will have to be lowered to achieve the same aero balance).
In fact, often a race car aerodynamicist will seek to maximise the downforce generated at the rear of the car. This is because the underfloor and diffuser are the most efficient downforce generating devices. A substantial amount of load can be generated here for very little drag. Hence it is more desirable to generate rear downforce via the underfloor and diffuser rather than the rear wing (which itself is one of the main sources of drag). Thus, if downforce can be ‘transferred’ from the rear wing to rear underfloor, then the same level of rear downforce can be achieved but with less drag,
thereby increasing the overall efficiency of the car. Thus, the general trend of front wing design is actually to maximise the downforce generated by the underfloor and diffuser.The above image illustrates the static pressure distribution around the front wing. This is the pressure exerted by the fluid (in this case the air) as it accelerates and decelerates around the wing elements. Orange to red indicates positive static pressure whilst green to blue indicates a negative static pressure. The lower surfaces are subject to the negative ‘suction’ pressure which acts to pull the wing down. The upper surfaces are subject to the positive pressure which also acts to push the wing down. In general, the suction pressure contributes a greater proportion of the overall downforce generated by the front wing.Another critical factor that has dictated the development of the front wing is the condition in which it operates within. Firstly, the front wing is the only major downforce generating device exposed to the undisturbed air. This means a high amount of energy can be ‘extracted’ by the front wing which manifests itself as downforce as well as drag. In other words, the front wing is aerodynamically very sensitive to small geometric changes and as a result, an unprecedented degree of complexity has arisen.Secondly, the front wing operates in ‘ground effect’. This is the phenomenon whereby as the proximity between ground and the front wing diminishes, an enhancement in downforce level is observed at an exponential rate (that is until the wing ‘stalls’ – more on this in the next article). Ground effect increases the efficiency of downforce production and is partly why the latest trend is to run the car at extreme rake (i.e low front ride height and high rear ride height means the front wing sits closer to the ground).Thirdly, because the front wing is mounted forwards of the front wheel axle line, small variations in front ride height can lead to relatively large changes in front wing ground proximity. Hence downforce levels can change dramatically leading to sudden and large shifts in aero balance. Therefore another goal of front wing design is to mitigate the amount of ‘ride height sensitivity’ to produce a car with consistent aero balance as the car navigates its way through the track. Ride height sensitivity mitigation is perhaps the most challenging aspect of the design, as the wing has to be optimised across a large operating range (this makes it computationally very expensive when developing in CFD).In the next article, we’ll take a deeper look into the underlying physics which drives the design of the front wing. We’ll investigate some of the fundamental aerodynamic mechanisms involved and study how their behaviour can profoundly influence the performance of the car.

I hope you will write another couple of articles about front wing, cause a lot of small intricate elements are unknown for peoples,who not so close with race cars.
I hope you will make it with a lot of pics and details)

Function Of Wing Slots
One can tell a great deal about how a bird lives just from its wing shape. Most passerines, doves, woodpeckers, and game birds have wings that taper down more or less to a point at their outer tip. Those wings have a low aspect ratio (ratio of length to width), designed for rapid takeoff and swift twisting flight, but not for sustained high speed. Narrowing the tips reduces the area subject to the drag-inducing formation of vortices. At each wingtip a spiraling vortex is formed as air spills from the high-pressure area under the wing into the low-pressure area over it. Tapering, low-aspect-ratio wings are found on birds that must be fast and agile in order to outmaneuver both their prey and their predators.
Slots between feathers at the tip of the wing lower the speed at which air flowing over the wingtip can cause enough turbulence to initiate a 'stall' (reducing lift so that the bird starts descending). Slots thus aid low-speed maneuvering and are better developed in small, agile birds such as wood warblers than in less-active species such as House Sparrows. They are also prominent features on the wings of crows and their relatives and of game birds. Flat, rather high-aspect-ratio wings lacking slots, and with feathers at the base that streamline the trailing edge in with the body, are found in falcons, swallows, plovers, and other specialists in high-speed flight. In contrast, hawks that soar in open country have lower-aspect-ratio wings; and Sharp-shinned Hawks that hunt in woodlands (and owls that also hunt there) and must be able to turn rapidly have an even lower aspect ratio. Wings that are more cambered (arched in cross section), with low aspect ratio and well-developed slots, characterize vultures and other soaring land birds, while extremely high-aspect-ratio wings characterize albatrosses and other oceanic 'slope soarers.'
