Words written at the beginning of the article: In fact, the author of articles on such reasons are from chatting with friends, I was very seriously child, so when encountered some who do not understand the problem, I like to go ferret out the reason may be, there are many car common-sense problem for us may have been the customary thing, but these habits as if the sun around the earth this "truth" is not accurate.
Many riders like to be modified after the car, some want to become more beautiful to enhance keep returning, and some people hope that improved the performance of the vehicle, while among all vehicle modifications to vehicles with tail is the largest and most common, and even many car brands Sport Edition models of the original car will be equipped with a tail, but this thing in the end why?
Automotive aerodynamics package definition
The term "aero" when you purchase your vehicle can often hear a lot of car brands, Sport Edition models will have a similar optional accessories or optional accessories, the sports version of the general domestic family cars just some of the installation of the so-called aerodynamic package such as the tail, the rear spoiler and underbody spoilers and so on.
Installation of a BMW M5 aerodynamic
First of all, let us first understand the concept of the so-called aerodynamic, which is a branch of fluid mechanics, its purpose is to find out the object in motion with the air between physical Heights changes in a subject, aerodynamics research is based on the relative velocity between the object and the air is less than 100km / s (360-400km / h relative velocity), while the car is compared to less than the speed of object, and automotive appearance The air flow is called incompressible airflow.
General aerodynamic test trials are specialized air flow testing laboratory
The top looked very troublesome thing, in fact, I had a headache, while speaking into the vernacular of aerodynamics is to figure out the size of an object by the air resistance.Aerodynamics on the car is to let the air flow stream of vehicle sheet formed with the help of the car is moving, or reduce the drawbacks of high speed air for the form of additional accessories, aerodynamic kit The main types of spoiler panels and car wing (spoiler) two only.

In fact, the origin of automobile tail is from the wing of an airplane, if you pay attention to the shape of the tail section very much like an airplane wing? Simple physical sense, aircraft take-off from the wing out to get a sufficient upward force, and the tail is just the opposite, it is the air flow to the fixed position to bring strong pressure, so that a fixed position without increasing the quality premise, let the ground adhesion to achieve maximized.
The air around the vehicle when the flow experiments
Aerodynamic package we brought most is the rear wing or spoiler, and most may think they are in fact one thing, but that is not the case, although the tail is an aerodynamics package, but in accordance with the provided for different purposes, the role of the tail (a lot of racing in front of the car will be assembling the front wing) is to add-in board to increase the air resistance of vehicles in a fixed position, it must be with the body have a certain distance.
