The previous chapter was a bit hasty, and this chapter will talk about this aerodynamics laboratory and this engine laboratory separately. These two aspects can be said www.biquge.info to be the core of all aircraft, and without the study of aerodynamics, then the plane is likely to not be able to fly. It is also through this observation and imitation that people have the structural appearance of today's airplane wings, and it is this structural appearance that makes today's aircraft fly higher and higher. And if there is no engine research, then the plane will not have the heart to power the aircraft, let alone fly, and it will not even be able to run. Jiang Chen also clearly remembered how much suffering and loss we suffered in terms of engines in later generations, and even the development of this engine technology with the strength of the whole country was only a small success, and it was still far from advanced countries.

Let's talk about this aerodynamics laboratory first, Jiang Chen actually wanted to build such a laboratory for a long time. Because this aerodynamic aspect is not only needed for aviation aircraft, but also for other aspects, especially for cars like Jiang Chen, who are researching and producing, they have to consider how to use this aerodynamics to study the shape and structure. Aerodynamics, to put it bluntly, is actually how to use the air resistance or friction encountered when an object is propulsed. Maybe we don't feel it personally, and you can't feel its resistance when you walk, but you and it is actually around you, for example, when you speed up, you will feel the wind, in fact, this is the resistance of the air. For example, the electric fan that we often blow is actually designed according to aerodynamics, what are the fan blades, the wind is strong, and the blowing is not concentrated and divergent, soft and not a headache, these are all scientific. Another typical example is this parachute, which can take people in the air and land slowly, in fact, it also uses the relevant principles of aerodynamics. But it's not about reducing the resistance, it's about how to increase it.

Why do you need it for automobile R&D and production, because the speed of the car can be hundreds of miles, and the air resistance it encounters is very large, if it is not treated, then the car is likely to be because of the relationship of air resistance, or the light is waste oil, or the speed can not be improved, and the heavy may cause the tragedy of car destruction and death. And as people become more and more affluent, the requirements for vehicles are not just transportation. In addition to the pursuit of more and more comfort, faster speeds are becoming more and more sought after. This led to the sports car series, which may not have had this concept in the 80s, but in later generations, I will ask which young man does not have a dream of a sports car, which boy does not want to be a sports car beauty, and which girl has not fantasized about the prince who drives a sports car. It can be seen that its position in the hearts of the people, and it is precisely because of people's pursuit that the sports car market is becoming more and more prosperous. And those sports car manufacturers have also made a lot of money from this, and a sports car even sells for tens of millions, which is not just a car.

Although there are so many car manufacturers in the world, sports cars are not so easy to build, and there are only a handful of companies that can build them. Because there are three main aspects that affect the speed of sports cars, all of which are high-tech industries. The first is the material, a good material should be strong and tough, but also lightweight, high temperature resistance, low temperature resistance, these factors also affect the overall performance of the sports car, and thus affect the speed. The remaining two aspects are the most important aspects of speed, one is the engine of the car, and the other is the aerodynamic design of the body. In terms of the engine of the car, this is the heart of the whole car, and the entire power of the car is provided by it, without a strong "heart", the speed of the car cannot be improved. But in addition to the engine, there is another factor that affects the speed of the car, that is, whether the design of the vehicle shape and the structure of the vehicle meet the requirements of aerodynamics. A powerful car can drive 100 miles (about 160 kilometers per hour), but an aerodynamically designed car can double its speed to 200 miles, which shows the importance of this aerodynamic. Therefore, many sports cars in later generations have paid attention to this aerodynamic design, so as to increase speed. Because in terms of engine, everyone's technology is similar, so the fight is the aerodynamic shape design of the vehicle. This is also why we see why so many sports cars are so technological or weird, which is specially designed to consider the aerodynamic shape.

According to the current development progress of the company's automobile industry, Jiang Chen and they will definitely enter the high-end automobile market, and this sports car industry must not be missed. Therefore, this aerodynamics laboratory is just right, which can not only meet the company's aircraft design research, but also take into account the development of automobiles and motorcycles, and even the company's paramotor and parachute, and can also play a great role in the research of missile body, rocket/projectile body, and even a small bullet flight attitude for the B17 factory.

Although this aerodynamics laboratory is very good and has a great effect, its cost is not small, and it is not affordable if you don't have a certain capacity. A large-scale supersonic wind tunnel will cost tens of billions in the future, which is definitely not something Jiang Chen and they can afford. Therefore, the wind tunnel that Jiang Chen and they are going to build must not be so large, but if it is too small, it will not be able to keep up with the development, or it will be eliminated in a few years, so a medium-sized subsonic wind tunnel (in M& lt; A wind tunnel of 0.3 is called a low-speed wind tunnel; lt; m& lt; A wind tunnel within the range of 0.8 is called a subsonic wind tunnel; lt; m& lt; The wind tunnel in the range of 1.2 is called a transonic wind tunnel; lt; m& lt; Wind tunnels within the range of 5 are called supersonic wind tunnels, and wind tunnels in M≥5 are called hypersonic wind tunnels. It's still very much in line with Jiang Chen's current needs. This is also a considerable amount of expenses, if it weren't for the company's good development progress this year, Jiang Chen probably wouldn't have been able to make up his mind.

Regarding the location of this aerodynamics laboratory, Jiang Chen and Lu Lao discussed and studied a lot, and finally decided to choose a separate site and not be with this park or aviation R&D base. After some research and discussion, Jiang Chen and the others decided to surround Nanshan. On the one hand, it can not occupy the reserve land of the park, and on the other hand, it can rely on infrastructure such as the Nanshan Service Center and the company's employee community, so that it can not be built separately and can save a lot of money.

Moreover, Jiang Chen also plans to develop this laboratory to attract other units, teams or individuals to come here to conduct relevant research experiments. On the one hand, it is to reduce some of the operating costs for it, and one is to introduce talents. Jiang Chen plans to take advantage of the current recession in the industry, and strive to reach an agreement with Vice Minister Luo tomorrow to introduce some experts and scholars in dynamics research from various units, and strive to build this laboratory into the top aerodynamics research laboratory in China.
