Xingchen Motors has launched a new model again.
Apart from the people within the Nanshan Group who were happy, Liu Tianwu was the happiest.
Although I have heard Cao Yang mention before that there are new models coming soon, and new factories are already being prepared.
But after all, there was no specific news coming out, so Liu Tianwu had no idea how this matter would turn out.
It's different now.
"Mr. Cao, your Xingchen Automobile is really a blockbuster without even making a sound."
"As the new project progresses, if you need any help from me, just ask."
Although Liu Tianwu had said similar words many times, this time he seemed more sincere.
Everyone was so familiar with each other, and Cao Yang was not polite.
Just two days ago, when he was making the clay model of Xingchen No. 3, Yao Yongxiang mentioned the car wind tunnel to him.
He feels that if a car, especially a sports car, does not have wind tunnel testing and relies solely on software simulation, its aerodynamic performance may not be optimal.
On ordinary cars and SUVs, this problem is not a big problem.
But on a sports car, this problem is magnified.
Similar styling, but the drag coefficient is much different.
This will not only affect fuel consumption, but also affect the dynamic performance 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. The drag coefficient and other aspects are already at their best.
But Yao 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 by itself, it is not so cost-effective.
A car wind tunnel costs hundreds of millions.
Although Cao Yang can also get it, it is a bit of a loss to use his own money to build such a laboratory that is not very practical.
"Leader, I really have something that I need your help in coordinating and advancing."
With such a good opportunity, Cao Yang would definitely bring up the matter of building a car wind tunnel with Liu Tianwu.
It would be good if the district or Yangcheng City came forward to build it.
It would be good to bring universities and other car companies to build it together.
Anyway, Cao Yang didn't want his family to pay for this money.
After all, if a car wind tunnel is exclusive to Xingchen Motors, its utilization rate will be very low.
Otherwise, all automobile-related enterprises and institutions in Lingnan Province will be brought together.
"Mr. Cao, why are you being polite to me?"
"If you have any questions, just ask them directly."
Liu Tianwu readily gave his answer.
"It's like this. The earth has complex and changeable climate phenomena. Varying and even extreme climates bring many unpredictable problems to the development of a new car."
"If there is a device that can simulate various climates on the earth, it will save a lot of road testing time for new car development."
"The Automotive Environmental Wind Tunnel has such equipment."
"In the automotive environment wind tunnel, the thermodynamic testing of the vehicle no longer depends on God's face. The simulated environment can be fully utilized 365 days a year to debug the entire vehicle development, thereby better controlling R&D costs and time. "
"So far, only Jilin University built a very simple automotive wind tunnel in 2003, and there is no other similar equipment in the country."
"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 China's first real automotive wind tunnel?"
This is the first time Liu Tianwu has heard of what Cao Yang said.
Isn't the wind tunnel only used in the design of aircraft and rockets?
Why should it be used in car design?
If you don't understand, just ask. Liu Tianwu didn't pretend to understand, and said directly: "Is this car wind tunnel important?"
"There were no automotive wind tunnels for so many years, and it seemed that various companies were developing normally."
Cao Yang didn't feel strange after hearing this.
It is normal for Liu Tianwu to have this question.
"Wind tunnel testing can test the air resistance of the car body and see how the airflow passes through the car body."
"Automotive wind tunnel testing is very important. The lower the air resistance, the higher the fuel economy of the car body design, and the smaller the resistance when driving at high speeds."
"When designers design the appearance of a car, they don't know how much resistance the air will cause to the body. At this time, wind tunnel testing is needed."
"A car, especially a sports car and racing car, needs to go through countless wind tunnel tests during the development process."
"Combined with these tests, some empty aerodynamic packages can be improved to make the car more stable at high speeds and increase the top speed."
"It can be said that the automobile wind tunnel is a large-scale device for studying automobile aerodynamics. Almost every car must undergo repeated testing and shape optimization in the wind tunnel during the design stage."
"And the wind tunnels that provide testing for top supercars often contain cutting-edge technology and are expensive to build. It can be said that 'a blast in the wind tunnel is worth a million dollars'."
"In the past, China's car styling basically followed the path of learning from the mature models of international automobile giants."
"In this case, it doesn't make much sense whether to do wind tunnel testing or not."
"But this shortcut is destined to be impossible to go on forever."
"Not to mention that Xingchen Motors is currently following the path of independent design, in the future BYD, Yangcheng Motors, and other car companies will definitely embark on the path of independent research and development."
“At that time, the need for automotive wind tunnels was even greater.”
“In addition, industries such as rail transit and drone design also have demand for wind tunnels.”
"Lingnan Province currently does not have a single wind tunnel testing equipment, which is very detrimental to the development of related industries."
"By building a 'technically leading and fully functional' automotive wind tunnel laboratory, establishing a complete automotive aerodynamics and thermodynamics test evaluation and technology research and development standard system, and establishing an operation service and exchange and cooperation model that keeps pace with the times and develops innovatively, This has a strong demonstration significance for Yangcheng City and even Lingnan Province."
To persuade Liu Tianwu to help lead the construction of a car wind tunnel, it is natural to explain its importance clearly.
Sure enough, after listening to Cao Yang's words, Liu Tianwu became much more interested.
"How much does such a car wind tunnel cost?"
"I estimate it may take about four to five billion."
"Huh? So expensive?"
Liu Tianwu originally thought that an investment of tens of millions would be enough.
After all, it is just a wind tunnel laboratory. It sounds like it can just blow air on the car.
I didn’t expect it would cost hundreds of millions.
This is 2005.
Spending hundreds of millions to build a laboratory, no wonder Cao Yang asked him to come forward to set it up.
Even Nanshan Group cannot bear this method of burning money.
"Leader, that's it."
"Automotive wind tunnels need to simulate testing conditions in various environments."
"With a few examples, it may be easier to understand why the investment in automotive wind tunnels is so large."
"First, how does the wind tunnel create various weather conditions to meet the needs of vehicle testing?"
"The temperature simulation range of wind tunnels generally needs to reach -40℃-60℃."
"In order to achieve low temperatures, a secondary refrigeration system is required in the wind tunnel to allow the refrigerant to conduct heat exchange in the wind tunnel flow channel through the coil."
"The realization of high temperature is to obtain heat through boiler heating, trying to save energy while accurately controlling the temperature."
If you want people to spend money, you must clearly explain the reason for the money.
Otherwise Liu Tianwu would not dare to push this project forward easily.
Such a large investment project obviously cannot be handled directly by the district, at least it must be at the level of Yangcheng City.
Even promoted to the entire Lingnan Province.
"Second, in order to achieve sunlight simulation in the wind tunnel, a full-spectrum sunlight simulation system needs to be considered at the top of the wind tunnel test section."
"In this system, each light source has an independent power supply and control system to achieve precise lighting control."
"At the same time, it is necessary to consider integrating mesh baffles and light-shielding baffles on each independent light source to simulate the low-irradiation intensity environment of the vehicle under dark cloud conditions and the no-irradiation environment when passing through the tunnel."
"Third, it is best for a car wind tunnel to be able to 'rain'."
"In order to implement rainfall simulation in a wind tunnel, it is necessary to consider installing a spray gun at the nozzle of the wind tunnel."
"According to different rainfall settings, the spray gun will spray raindrops of corresponding sizes. The raindrops will be blown to the test vehicle with the airflow from the nozzle to form rainfall. Real rainfall of different levels such as light rain, moderate rain, and heavy rain can be simulated."
"In addition, snow and other environments also need to be considered for simulation."
"The automotive wind tunnel must truly simulate various climate conditions such as temperature and humidity, sunlight, rain and snow, and cooperate with various road conditions simulated by the chassis dynamometer. It can conduct rainfall tests, snowfall tests, and high and low temperature shocks unique to environmental wind tunnels. Waiting for the climate test.”
“The above only describes some of the design requirements for some wind tunnels. When these requirements are accumulated, the investment required will be very huge.”
Now that we have to consider letting Liu Tianwu help promote the automotive wind tunnel project.
Cao Yang will definitely not just build a simple wind tunnel that can blow wind.
Taking this opportunity to combine other climate tests, it can really play a real role in the development of new models later.
For example, when developing new models, they need to go to severe cold areas for testing, they need to go to hot areas for testing, and they also need to go to plateau areas for testing.
Not to mention that the testing environment is difficult and the cost investment is relatively high.
The time wasted alone is also a pity.
If there is such a car wind tunnel, then many tests can be completed in the laboratory.
Even if some of them need to go to Mo/He, TLF and other automotive testing grounds for field testing, a lot of testing items can be saved.
This is of great significance for reducing the development time of new models.
"Listen to what you said, this laboratory is not a simple car wind tunnel at all?"
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 based on the principle of similarity of motion, and uses high-speed airflow to flow through the surface of the car to simulate the aerodynamic characteristics of the car under actual road driving conditions.
Just build a huge blower and build a house, that's basically enough.
I didn't expect that this was not the case at all.
"Leader, there is currently no decent automotive wind tunnel in China. If we want to build one, we must build a domestically leading and world-class laboratory."
"At the same time, in the future, in order to give full play to the effectiveness of this automotive wind tunnel, promote the advancement of wind tunnel technology in the industry, accelerate the quality upgrading of domestic independent brand automobiles, and achieve the sustainable development of Chinese automobile companies."
"The district can join forces with the China Automobile Association to form an automotive wind tunnel alliance. Through this alliance, the district can establish contact with major domestic independent brand car companies, so as to develop technologies in the fields of automotive aerodynamics, aeroacoustics, thermodynamics and other fields. R&D and cooperation exchanges have become closer.”
"Maybe in the future, in addition to Xingchen Motors and Yangcheng Motors, other car companies will come to develop."
“This should be attractive to both Yangcheng City and Lingnan Province.”
This is not the first day that Cao Yang has dealt with Liu Tianwu.
Knowing where to focus when doing things when sitting in his position.
Obviously, if this automotive wind tunnel is only for Xingchen Automobile, then the project will be promoted with a somewhat unfair reputation.
But if the positioning and intention are raised a little higher, the situation will be completely different.
Sure enough, after hearing what Cao Yang said, Liu Tianwu was tempted.
"Mr. Cao, please arrange for someone to assist in submitting the design requirements and budget related to the automotive wind tunnel. I will ask secretary Luo Yi to contact him."
"Try to submit the project this month and finalize the project within the year."
"Then it will be constructed next year and completed next year so that Xingchen Motors can quickly use the wind tunnel."
When Liu Tianwu said this, Cao Yang couldn't help but smile.
Then he continued to say: "Leader, if Yangcheng or Lingnan Province cannot fund it alone, they can join forces with Lingnan University of Technology, Yangcheng Automobile Group, Xingchen Automobile, BYD and other scientific research institutes to fund it."
"By operating this automotive wind tunnel laboratory as a separate enterprise unit, the financial pressure and construction threshold in all aspects should be greatly reduced."
Cao Yang naturally didn't want to make Liu Tianwu so embarrassed.
After all, it is an investment of four to five billion. No matter how it is explained at the time, Xingchen Automobile will definitely be the first to enjoy the benefits of this laboratory.
At that time, people will inevitably feel that Liu Tianwu's butt is sitting on Xingchen Automobile's side.
"If we proceed in the direction you mentioned, I will be more confident."
"This simple investment can also become a new investment project."
Liu Tianwu naturally understood the meaning behind Cao Yang's plan.
For the district, with the addition of such a project, next year’s data will definitely be better.
