Chapter 757 Importance of Aerodynamics Research Laboratory

What was said in the previous chapter was a bit hasty. In this chapter, I will talk about the aerodynamics laboratory and the engine laboratory separately.These two aspects can be said to be the core of all aircraft. Without the study of aerodynamics, the aircraft may not be able to fly.It is also through this observation and imitation that people have the structure of today's aircraft wings, and it is this structure that makes current aircraft fly higher and higher.And if there is no research on the engine, then this aircraft will not have a heart to power the aircraft, let alone fly, it will not even be able to run.Jiang Chen also clearly remembers how much suffering and loss we have suffered in the engine industry in future generations. Even if we use the power of the whole country to develop this engine technology, it is only a small success, which is far behind the advanced countries. Woolen cloth.

Let’s talk about the aerodynamics laboratory first. Jiang Chen actually wanted to build such a laboratory a long time ago.Because this aspect of aerodynamics is not only needed for aerospace vehicles, but also for other aspects, especially for cars like Jiang Chen and his research and production, it is even more necessary to consider how to use this aerodynamics to study the shape and structure.The so-called aerodynamics, to put it bluntly, is actually how to use the air resistance or friction encountered when an object is propelled.Maybe we can't feel it personally, and you can't feel its resistance when you walk, but it is actually by your side. For example, after you speed up, you will feel the wind. In fact, this is the resistance of the air.For example, the electric fans we often blow are actually designed according to aerodynamics. What is the shape of the fan blades, the wind is strong, and the blowing does not concentrate and diverge, and it is gentle and does not cause headaches. These are all science.Another very typical example is this parachute. The reason why it can carry people down slowly in the air is actually based on this aerodynamic principle.But it is not reducing the resistance, but how to increase the resistance.

Why is it necessary for automobile research and development and production? Because the speed of a car can reach hundreds of miles, the air resistance it encounters is very large. The relationship, at least, is waste oil, or the speed cannot be improved, or at worst, it may lead to a tragedy of car crash.And as people become richer and richer, the requirements for vehicles are no longer just transportation.In addition to pursuing its more comfortable, faster speed is more and more sought after.This has led to the series of sports cars, which may not have had this concept in the 80s, but in later generations, which young people do not dream of a sports car, which boys do not dream of beauties in sports cars, and which girls do not dream of princes driving sports cars.It can be seen that its status in the hearts of the people is precisely because of people's pursuit, which makes the sports car market more and more prosperous.And those sports car manufacturers also made a lot of money from this, and a sports car even sold for tens of millions, which is not just a car.

Although there are so many automobile manufacturers in the world, sports cars are not so easy to manufacture, and there are only a handful of companies that can manufacture them.Because there are three main aspects that affect the speed of sports cars, all of which are high-tech industries.The first one is the material aspect. A good material should be strong and tough, but also light in weight, resistant to high temperature and low temperature. These factors also affect the overall performance of the sports car, thus affecting the speed of the car.The remaining two aspects are the most important for speed, one is the engine of the car, and the other is the aerodynamic design of the car body.In terms of the car's engine, 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 increased.But in addition to the engine, there is another factor that also 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 up to 160 miles (about [-] kilometers per hour), but an aerodynamically designed car can double the speed to [-] miles. It can be seen that this aerodynamic importance.Therefore, many sports cars of later generations pay great attention to this aerodynamic design to increase speed.Because in terms of engines, everyone's technology is similar, so the aerodynamic shape design of the vehicle is what we are fighting for.This is why we see that so many sports cars are so technological or weird, they are specially designed to consider the aerodynamic shape.

According to the current development progress of the company's automobile industry, Jiang Chen and the others will definitely enter the high-end automobile market, and this sports car industry must not be missed.So this time the aerodynamics laboratory is just right, it can not only meet the research of the company's aircraft design, but also take into account the research and development of automobiles and motorcycles, and even the company's powered parachutes and parachutes. In terms of missile body, rocket/bomb body, and even the study of the flight attitude of a small bullet, it is very useful. It can be said to serve multiple purposes.

Although this aerodynamic laboratory is very good and has a great effect, its cost is not small, and it cannot be afforded without a certain ability.A large supersonic-level wind tunnel would cost tens of billions in future generations, which is definitely not something that Jiang Chen and the others can afford.Therefore, the wind tunnel that Jiang Chen and the others plan to build must not be that big, but if it is too small, it will not be able to keep up with the development, and it will be eliminated in a few years, so a medium-sized subsonic wind tunnel (in M& amp;lt;0.3 wind tunnels are called low-speed wind tunnels; wind tunnels in the range of 0.3<M<0.8 are called subsonic wind tunnels; 0.8<M& amp;lt;1.2 wind tunnels are called transonic wind tunnels; 1.2<M<5 wind tunnels are called supersonic wind tunnels; M≥5 wind tunnels are called It is a hypersonic wind tunnel.) It is still in line with Jiang Chen's current needs.Even this is quite a large expense. If it weren't for the company's development progress this year, Jiang Chen might not be able to make up his mind.

Regarding the location of the aerodynamics laboratory, Jiang Chen and Mr. Lu discussed and studied a lot, and finally decided to choose a separate location, not with this park or the aviation research and development base.After some research and discussion, Jiang Chen and the others decided to stay around 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 Nanshan Service Center and the company's employee community, so that no additional construction is required, and a large amount of money can be saved.

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