Xingchen Automobile has a new model.

In addition to the happiness of the people within the Nanshan Group, Liu Tianwu is the happiest.

Although I have heard Cao Yang mention before, there are new models to come up in the future, and the new factory is already being prepared.

But after all, there is no specific news coming out, what will this matter become, Liu Tianwu has no idea in his heart.

Now it's different.

"Mr. Cao, your Xingchen car is really a blockbuster."

"In the process of advancing the new project, if there is anything you need me to help with, just say."

Although Liu Tianwu has said similar things many times, this time he seems to be more sincere.

Everyone is so familiar, Cao Yang is not polite.

Just two days ago, when he was making the clay model of Xingchen No. 3, Huan Yongxiang mentioned to him about the car wind tunnel.

He felt that the aerodynamic performance of a car, especially a sports car, would not necessarily be optimal if there was no wind tunnel test and software simulation alone.

In the case of ordinary sedans and SUVs, this problem is not a big problem.

But on top of a sports car, the problem is magnified.

The shape is almost the same, but the drag coefficient is much worse.

This will not only affect fuel consumption, but also affect the dynamics of the car.

Even more seriously, it will affect the safety of the car.

Although this Xingchen No. 3, Cao Yang directly copied Ferrari's flagship sports car launched in 2013, and the drag coefficient or something is already in the best condition.

But Huan Yongxiang doesn't know.

In order to consider new models in the future, it is really necessary to build a car wind tunnel.

However, if Xingchen Automobile does it itself, it is not so cost-effective.

A car wind tunnel will cost hundreds of millions casually.

Although Cao Yang can also take it, it is a bit of a loss to use his own money to build this kind of laboratory that is not so practical.

"Leader, I really have something I need your help to coordinate and promote."

With such a good opportunity, Cao Yang must propose to Liu Tianwu the matter of building a car wind tunnel.

It is also good for the district or Yangcheng to come forward to build.

It's good to pull the university and build it with other car companies.

Anyway, Cao Yang doesn't want to make this money by himself.

After all, a car wind tunnel, if it belongs to the exclusive of Xingchen Automobile, then the utilization rate is also very low.

Otherwise, the entire Lingnan Province will be brought together with automobile-related enterprises and institutions.

"Mr. Cao, what are you polite to me?"

"If there's a problem, just say the problem."

Liu Tianwu gave his answer very happily.

"Yes, the earth has complex and changeable climatic phenomena, and the ever-changing and even extreme climate brings many unpredictable problems to the development of a new car."

"If there is a device that can simulate all the climates on the planet, it will save a lot of time for road tests in the development of new cars."

"And the automotive wind tunnel has such equipment."

"In the automotive environment wind tunnel, the thermodynamic test of the vehicle no longer needs to 'look at God's face'', and the simulated environment can be fully used to debug the vehicle development 365 days a year, so as to better control the cost and time of research and development."

"So far, only Jida built a very simple car wind tunnel in 2003, and there is no other similar equipment in China."

"So I'm wondering if Lingnan Province can organize transportation departments, scientific research institutes, universities, enterprises and other institutions to take the lead in building the first real automobile wind tunnel in China?"

This thing Cao Yang said, Liu Tianwu really heard of it for the first time.

Isn't the wind tunnel only used in the design of airplanes and rockets?

How can it be used in car design?

If you don't understand, you ask, Liu Tianwu didn't pretend to understand, and said directly: "Is this car wind tunnel very important?" ”

"There were no car wind tunnels for so many years before, and it seems that various enterprises are also developing normally."

Cao Yang didn't feel strange when he heard it.

It is normal for Liu Tianwu to have this question.

"Wind tunnel tests can test the air resistance of the empty body and see how the airflow passes through the body."

"Wind tunnel testing is very important. The lower the air resistance, the higher the fuel economy of the car body design, and the lower the drag at high speeds. ”

"When designers design the exterior of a car, they don't know how much resistance the air will have on the body, so that's when a wind tunnel test is needed."

"A car, especially sports cars and racing cars, needs to go through numerous wind tunnel tests during the development process."

"Combined with these tests, some empty aerodynamic kits can be improved, making the car more stable at high speeds and increasing the ultimate speed."

"It can be said that as a large-scale device for studying automobile aerodynamics, almost every car has to be repeatedly tested and optimized in the wind tunnel during the design stage."

"The wind tunnel itself, which provides testing for top supercars, often contains cutting-edge technology and is expensive, so it can be said that 'the wind tunnel rings, the gold is ten thousand taels'."

"In the past, Huaxia's car styling basically took the road of borrowing from the mature models of international auto giants."

"In this case, it doesn't make so much sense to do wind tunnel tests or not."

"But this kind of shortcut is destined to go on forever."

"Not to mention that Xingchen Automobile is now taking the road of independent design, whether it is BYD, Yangcheng Automobile, or other car companies in the future, they will definitely embark on the road of independent research and development."

"At that time, the demand for automotive wind tunnels was even greater."

"In addition, industries such as rail transit and drone design actually have a demand for wind tunnels."

"Lingnan Province does not have a single wind tunnel test equipment, which is very unfavorable to the development of related industries."

"Through the construction of a 'technology-leading, functional' automotive wind tunnel laboratory, a complete automotive aerodynamics and thermodynamic test evaluation and technology research and development standard system, and the establishment of an operation service and exchange and cooperation model that keeps pace with the times and innovates and develops, this has a strong demonstration significance for Yangcheng City and even Lingnan Province."

To persuade Liu Tianwu to help take the lead in building a car wind tunnel, it is natural to explain its importance clearly.

Sure enough, after listening to Cao Yang's words, Liu Tianwu's interest was much higher.

"How much does it cost to build such a wind tunnel?"

"I estimate that it may take about four or five hundred million."

"Huh? So expensive? ”

Liu Tianwu originally thought that an investment of tens of millions would be enough.

After all, it's just a wind tunnel lab, and it sounds like it's just a thing to be able to blow the wind on a car.

I didn't expect it to cost hundreds of millions.

This is 2005.

Spending hundreds of millions to build a laboratory, no wonder Cao Yang wanted to ask him to come forward to set it up.

Even Nanshan Group can't afford such a money-burning method.

"Leader, that's right."

"Automotive wind tunnels need to simulate testing situations in a variety of environments."

"To give a few examples, it may be easier to understand why the investment in automobile wind tunnels is so large."

"First, how can the wind tunnel create a variety of weather conditions to meet the needs of vehicle testing?"

"The temperature simulation range of the wind tunnel generally needs to reach -40°C to 60°C."

"To achieve low temperatures, a secondary refrigeration system is required in the wind tunnel, where the refrigerant is transferred through a coil in the wind tunnel flow channel."

"The realization of high temperature is to obtain heat through boiler heating, and try to save energy while accurately controlling the temperature."

If you want people to spend money, you must make the reason for spending money clear.

Otherwise, Liu Tianwu would not dare to push this project up easily.

Such a large investment project is obviously not something that can be handled directly in the district, at least at the level of Yangcheng.

It was even promoted to the entire Lingnan Province.

"Second, in order to achieve solar simulation in the wind tunnel, a full-spectrum solar simulation system needs to be considered at the top of the wind tunnel test section."

"On this system, each light source has an independent power supply and control system to achieve precise control of light."

"At the same time, the integration of mesh baffles and shading baffles needs to be considered on each individual light source to simulate a vehicle in a low-intensity environment under dark cloud conditions and a no-illumination environment when passing through a tunnel."

"Thirdly, it is better for the car wind tunnel to be able to 'rain'."

"In order to achieve rainfall simulation in the wind tunnel, it is necessary to consider installing a spray gun at the nozzle in the wind tunnel."

"According to the different rainfall settings, the spray gun will spray raindrops of corresponding size, and the raindrops will blow to the test vehicle with the air flow of the nozzle to form rainfall, and different levels of real rainfall such as light rain, moderate rain, and heavy rain can be simulated."

"In addition, environments such as snow also need to be considered for simulation."

"The automobile wind tunnel should truly simulate various climatic conditions such as temperature and humidity, sunlight, rain and snow, and cooperate with various road conditions simulated by the chassis dynamometer, which can carry out unique rainfall tests, snowfall tests, high and low temperature impact and other climate tests in the environmental wind tunnel."

"These are just some of the design requirements for wind tunnels, and the cumulative investment required for these needs is huge."

Since we have already considered the project of the automobile wind tunnel, let Liu Tianwu help to promote it.

Cao Yang will definitely not just build a simple wind tunnel that can blow the wind.

Taking this opportunity, the combination of other climate tests can really play a real role in the development of new models in the future.

For example, when developing a new model, you need to go to a cold area for testing, you need to go to a hot area for testing, and you need to go to a plateau area for testing.

Not to mention that the test environment is more difficult and the cost investment is relatively large.

It's a shame to spend a lot of time.

If there is such a car tunnel, many tests can be done in the laboratory.

Even if some of them need to go to Mo/He, TLF and other automotive test sites for field testing, it can also save a lot of test items.

This is of great significance in reducing the development time of new models.

"Listen to what you say, this laboratory is not a simple car wind tunnel at all, is it?"

Liu Tianwu also understood a little bit what the laboratory Cao Yang was talking about.

According to his understanding, the wind tunnel is a test equipment that fixes the car on the ground according to the principle of similarity of motion, flows through the surface of the car through high-speed airflow, and simulates the aerodynamic characteristics of the car in the actual road driving state.

Just build a huge blower and build a house, and that's basically enough.

I didn't expect it to be the case at all.

"Leader, there is no decent automobile wind tunnel in Huaxia today, if we want to do it, we must build a leading domestic and international first-class laboratory."

"At the same time, in the future, in order to give full play to the efficiency of this automobile wind tunnel, promote the technological progress of the wind tunnel in the industry, accelerate the upgrading of the quality of domestic independent brand vehicles, and realize the sustainable development of Huaxia automobile enterprises."

"The district can cooperate with the China Automobile Association to form an automobile wind tunnel alliance, through which the district can establish contacts with major domestic independent brand car companies, so as to become closer in the fields of automotive aerodynamics, aeroacoustics, thermodynamics and other fields of technology research and development and cooperation exchanges."

"Maybe in the future, in addition to Xingchen Automobile and Yangcheng Automobile, there will be other car companies that will come to develop."

"This should be attractive to both Yangcheng City and Lingnan Province."

It's not the first day Cao Yang has dealt with Liu Tianwu.

Know where to sit in his position and where to focus on doing things.

Obviously, if this car wind tunnel is only for the service of Xingchen Automobile, then the project is a bit unjustifiable.

But if you raise the positioning and intention a little higher, the situation is completely different.

Sure enough, after hearing Cao Yang's words, Liu Tianwu was moved.

"Mr. Cao, you arrange for someone to assist in submitting the design requirements and budget related to the automobile wind tunnel, and I will ask the secretary Luo Yi to connect with him."

"Strive to report the project this month, and give the project within the year."

"Then it will be constructed next year and completed next year, so that Xingchen Automobile can quickly use the automobile wind tunnel."

As soon as Liu Tianwu said this, Cao Yang couldn't help but smile on his face.

Then he continued to mention it: "Leader, if Yangcheng or Lingnan Province has no way to contribute alone, you can join Lingnan University of Science and Technology and Yangcheng Automobile Group, Xingchen Automobile, BYD and other scientific research institutes to contribute." ”

"By operating this automotive wind tunnel laboratory as a separate business unit, the financial pressure and construction threshold in all aspects should be greatly reduced."

Cao Yang naturally didn't want Liu Tianwu to become so embarrassed.

After all, it is an investment of four or five billion, no matter how it is explained at that time, the first to enjoy the benefits of this laboratory must be Xingchen Automobile.

When the time comes, it will inevitably make people think that Liu Tianwu's ass is sitting on the side of Xingchen Automobile.

"If you go in the direction you said, then I'll be more sure."

"This simple investment can also be turned into a new project to attract investment."

Liu Tianwu naturally understands the meaning behind Cao Yang's plan.

For the district, with such a project, next year's data will definitely look better.
