1、F1赛车高端科技详细图解（Formula one car high-end technology detail graphic）F1 on aerodynamic kit including wing, wing, tail, but its body construction is also cater to the aerodynamics: F1 has very strict requirements on aerodynamics, so it is very important to car wing section. Nose wing, flank, tail, in F1 r
2、ace, obviously the nose is more important. Because of its location, it controls the flow of air in the rest of the car. For the use of the wing, the fia also has strict dimensions. The diameter of the front wing should not exceed 1400 mm, the depth is not more than 550 mm, and the height is not more
3、 than 200 mm. But the front wing Numbers dont want to be limited to two. The front wing material is made of carbon fiber, though hard enough to be damaged by aerodynamic forces, but it can easily crash. In particular, because it is in front of the front wheel, it is especially easy to start and over
4、take the car because of the collision caused the front wing damage and have to go to the maintenance station to replace. The rear wing is very simple, but it is firmly on the ground. The production of the fia gauge rear wing must comply with a range of 1000 mm wide, 350 mm long and 200 mm deep. It m
5、ust also have enough strength to withstand a force of 1000 newtons of gravity. For different venues, the convoys generally have high, medium and low pressure rear wings.Formula one car high-end technology detail graphicAerodynamic AerodynamicsMechanical classification: low speed aerodynamicsFlow typ
6、e: incompressible flowFlow velocity: less than 400Km/hResearch content: lower pressure and resistanceResearch methods: model testIntroduction to aerodynamicsAir dynamics is a branch of fluid mechanics, is the study of the movement of air or other gas, air or other gas with aircraft or other objects
7、when the relative motion of interaction and accompanied by physical and chemical changes of the subject. It is a subject that is formed on the basis of fluid dynamics with the development of aerospace technology.Aerodynamic research content according to the relative velocity of air and object, if le
8、ss than about 100 m/s (i.e. speed of 360 km/h, note, there are divided according to the speed of 400 km is bounded), can be divided into low speed aerodynamics and high speed aerodynamics, the former research incompressible flow, the latter research compressible flow. Formula one racings research is
9、 the former. In addition, the viscosity can be divided into ideal aerodynamics and viscous aerodynamics.The purpose and core of F1 aerodynamics researchIn formula one, to study the dynamics of air core aim is to guarantee the car get enough pressure has the smallest air resistance, in order to impro
10、ve the speed and the stability of the high speed of the car, all serve for aerodynamic components, known as aerodynamic kit.According to experts, formula 1 teams currently spend 15% of their annual budget on aerodynamics, second only to engine development. A significant portion of this huge cost has
11、 been invested in wind tunnel construction and testing. The Wind Tunnel is a large Tunnel or pipe with a giant fan installed in the middle of the pipe.It can produce a strong flow of force, through grille and other devices to reduce the eddy current into the experiment section, and blow the experime
12、ntal model in it.The main function of the modern wind tunnel is to put the car model on the inside of the steel conveyor belt to simulate the various conditions on the road. In the wind tunnel test, the maximum speed of the large carbon fiber fan can reach 600 RPM, and the peak power of the driving
13、engine can reach the staggering 4000 horsepower. So strong motivation can within 30 seconds to the stillness of the air speed to 300 km/hour, at this time in order to motor model of conveyor belt is simulated in the game in various road conditions and automobile body posture, the maximum guarantee t
14、he authenticity and validity of simulation. Through the comprehensive analysis of the collected data, it can accurately detect the situation of the car on the road under various factors. This simulation can increase the precision of the aerodynamic components of a racing car by 30%. Today, leading F
15、1 are at a huge sum of money (a modern F1 wind tunnel cost more than $45 million), building their own wind tunnel, in order to timely and accurate research racing aerodynamic effect, improve the cars aerodynamic kit, overcomes the assassins mace.The three most important aspects of F1 aerodynamics re
16、searchIn the aerodynamics experiment, engineers focus on three main things: lower pressure, resistance and sensitivity. Under huge pressure to improve cornering limit car, but ideally, the increase of the pressure should not be to bring the car resistance increases, but inevitably will sacrifice part of the speed of the car. The cars aerodynamic sensitivity (sensitivity) refers to the state for the aerodynamic performance
