1 wing
Introduction:
wing is a piece of the tail of the car like a flip of the tail of the aircraft. Its main role is to effectively reduce the air resistance of the car at high speeds and save fuel. As the wing aerodynamic device to provide high-speed cornering car under pressure. The size of the wing race cases, there are strict limitations.
Origin:
airplane understand the principle of people know that all aircraft can fly overhead because it produces lift during takeoff acceleration, it sent the blue sky, from the date of birth aircraft from a new science comes into being, and this is aerodynamics.
is different from the aircraft, Fl racing applications aerodynamics for pursuit is totally reversed, in order ldquo; preparedness rdquo; car fly at high speeds, the aerodynamic means required to through some racing under constant pressure, while providing grip for racing, but also has its own F1 car wings mdash; mdash; front wing and a rear wing and other aerodynamic parts.
in the F1 car aerodynamic applications mainly in two aspects: first, allow the wing to produce a pressure sufficient to provide the tire grip, the other is to minimize the car is traveling air resistance. In the early years of the F1 race, racing and ordinary cars look very different, but since the introduction of aerodynamics, F1 racing began to appear significant changes, the first is scheduled to produce the wing. The basic principle of the wing and the wing of fact, we have seen an ordinary aircraft is the same, the biggest difference is that when an airplane wing aircraft because of the speed and generate enough lift, the car will wing wing It is inverted lift works. Installation of forward and reverse, rear wing will allow air to generate power drop, generally we call ldquo; rdquo ;, under pressure to ensure that the car traveling at high speed in the ldquo;Seize rdquo; even the ground will not cause large swings in floating and even rollover. F1 car is capable of producing wing corresponds to 3.5 times the weight of the car under pressure.
In the 1960s, the wing began to be used in F1 racing, F1 racing speed generally lead to improved, but because each team lack of adequate security in the use of wing, and the attendant It is to increase the accident, so the 1970 F1 rules for size and applications wing has made restrictions, such restrictions has continued to the present.
dynamics:
vehicle will encounter air resistance during running, such resistance can be divided into longitudinal, lateral, vertical, and the three force, and air resistance is proportional to the square of the vehicle speed, the faster the speed, the greater the air resistance. Generally, when the vehicle speed exceeds 60km / h, the air resistance of the car behaves very obvious. To effectively reduce and overcome the influence of air resistance when the high-speed car, automobile tail been designed, its role is to generate a fourth car air force. That’s adhesion to the ground, it can offset part of the lift, control the car go up, reduce windage effects, so that the car can close the roads, thereby improving driving stability.
car wing is at a pressure generated at different angles is not the same, while the front and rear wings and the angle is directly related to the track, and since the resistance of air under pressure is inversely proportional to, if winglet given wind angle, then the air resistance of the car is small, the maximum speed is large, but the absence of pressure and stability of the car; the contrary, if the wing angle is large, then the resistance of the car is large, the maximum speed is affected, but racing in the corners grip is strong. Therefore, according to different angles, disposed wing track are different. In general, if the track long straights, such as Germany, Hockenheim and Monza in Italy, then reduce angle; if the track bend over, such as Monte Carlo, Monaco, then turn up the angle. While Formula One is a high-speed car, but on a mechanical concept but closer to the Jets, rather than the family car. Not only with their huge wings role with commercial billboards, but also can have a crucial ldquo; under pressure rdquo ;. This causes the aerodynamic flow flowing over the car body is pressed down, so that the car tightPosted in the driveway. On the contrary, the aircraft is the use of huge wings generated ldquo; rising force rdquo ;. The body can tire pressure in the driveway to get more grip, thereby creating a faster acceleration in the corners. Since ordinary car is not under pressure, not even generate 1G (a unit of gravity) cornering force. Formula 4 can generate cornering force G is. In the case of 230 km per hour when, at a pressure above the airflow F1 racing it is sufficient to travel in the tunnel along the bottom of the tunnel.

A can body is pressed against the driveway greater grip of the tire, thereby generating a curve at a faster acceleration. Since ordinary car is not under pressure, not even generate 1G (a unit of gravity) cornering force. Formula 4 can generate cornering force G is.
is in a condition of 230 kilometers per hour, at a pressure above the airflow F1 racing it is sufficient to travel in the tunnel along the top of the tunnel.
in the design of today’s Formula One racing course, play an important role in the aerodynamics family is facing a fundamental challenge: how to produce under pressureWithout increasing the air resistance. This is the car must overcome.
In the automotive aerodynamic design process, wind tunnel plays an important role. When the wind tunnel test, typically to half volume production model, while a large wind tunnel like blower, the air blown static model.
can be adjusted according to the aerodynamic characteristics of the different racetrack. Pressure setting value straighter require lower track, so the resistance can be reduced, and contributes to improve the car speed. More tortuous lane requires a high downforce set value, so can make the car speed decreases. For example, in the tortuous Hungaroring lane, the car difficult to reach 300km / h speed, but in Monza lane, the speed can be more than 348km / h.
Materials:
Most cars are tail with glass fibers or carbon fibers, both lightweight and tough, and it is by design of the shape and size Teachers accurate calculation determined, should not be too large nor too small, otherwise it will increase car traffic resistance or achieve its proper role.
Function:
As the flip wing aircraft wing, the wing generates a lifting force of the wing is produced under pressure. Wing on the F1 car can produce nearly 60 percent at a pressure of the entire vehicle, to improve stability and cornering speed of the car, one of the source, but also the air resistance of the car itself, affect the car speed. Typically, the percentage of 25 under a pressure generated by the front wing of the car at the total pressure, the wing 33 as a percentage. Rules on aerodynamics 2004 F1 season clearly defined: after racing wing is limited to two, turned out to be three. In addition to reducing the resistance of high-speed driving, fuel savings for the installation of the tail will also help. In displacement of 1.6 liters of car, for example, if fitted with tail, reduced by 20 percentage air resistance coefficient, traveling on a general road, may not significantly reduce fuel consumption. If driving on the highway, it can fuel about 10 percentage.
