Automotive Black Technology Chapter 171: : Race against time

www.lnmao.org, the fastest update to the latest chapter of automotive black technology!

In nature, the object with the smallest known air resistance is a water droplet, and its drag coefficient is 0.03.

Among all human means of transportation, airplanes have the least wind resistance. my country's latest off-line J-31 fighter jet has a drag coefficient of only 0.08.

The drag coefficient of most passenger cars is between 0.25-0.4.

So the drag coefficient of A40.23 undoubtedly gave Li Fanyu a shot in the arm who was worried!

Because of this result, even if it is placed in a sports car, it is still an excellent result.

Wang Dazui and a group of students were speechless; the students were happy because they also had their own contributions to this achievement. Wang Dazui was surprised. After being immersed in the automobile industry for so many years, he had never seen a B-class car that could control wind resistance to this extent!

The slow white smoke was still blowing with the strong wind. The blue model was like a dagger, riding the wind and waves in the airflow, leaving only a beautiful streamline on the body.

Wang Dazui wiped his eyes in disbelief and took a closer look at the parameters on the instrument.

That’s right, it’s still 0.23!

"Hey! Awesome!" He slapped his thigh hard, picked up the SLR, put the instrument and the model on the side in the same frame, and clicked the shutter.

……

On the way back with the clay model, Li Fanyu laughed from Nanhe to Tiancheng.

Five minutes after the results came out, An Ning received a good news call from Li Fanyu. When she announced the news to the students, the entire laboratory was filled with joy.

Li Fanyu almost got carried away when he returned to the company. He looked at An Ning and shook his head with a smile. Only then did he resist the urge to pick her up and spin her around hard.

After celebrating with the students for a long time, Li Fanyu returned to the office. Sure enough, within five minutes, An Ning knocked on the door and came in.

Li Fanyu hurriedly stood up from the chair, walked to her side in two steps, and hugged her into his arms.

An Ning hugged his back and said with a smile: "I didn't expect it to go so smoothly."

Li Fanyu smelled the unique fragrance of her body and murmured: "It's not bad if everything goes smoothly. Is there something going to go wrong?"

"Poor talk. After the car model is decided, it's time to build the digital model of the car body. You are exhausted these days, so I will lead the team to do this."

Li Fanyu leaned back and pressed his forehead against An Ning: "Are you feeling sorry for me?"

An Ning didn't hesitate, she nodded her toes and rubbed her nose against his lips, then smiled and said, "When did I not feel sorry for you?"

Li Fanyu chuckled, "Then feel sorry for me tonight..."

An Ning spat at him, broke away from his arms like a butterfly, and stood aside.

How could Li Fanyu miss such a good opportunity? He immediately started chasing after her and acting cute. I couldn't bear to be annoyed by An Ning being pestered by him, so I finally blushed and stopped refusing.

But the two of them couldn't do it during the day. After chatting for a while, they got down to business.

The reason An Ning takes on the task of modeling body data is because the workload in this part is too large. It is necessary to program and design all the parts of the car body, and then implement them on the computer to create a 3D model. The trivial parts have to be processed one by one, and as long as there is a mismatch, it must be pushed to the next step. Therefore, this aspect is the most troublesome in vehicle design.

But she didn't know there was such a thing as Xapp, and all the parts data was stored in Li Fanyu's heart. So if you want to save time to the greatest extent, this job is really for Li Fanyu.

After carefully planning the process, Li Fanyu said: "I will do the data modeling. This aspect is my advantage. When you were at Mercedes-Benz, body safety protection design and body lightweighting were the top priorities. I'm a professional, you can do these two things, I won't argue with you. Our time is very tight, modeling, safety design, lightweight design, and making the prototype must be completed within two months. I have to race against time!"

When An Ning heard what he said, her almond-shaped eyes widened, "How is that possible? Not to mention these four links, just the modeling part. If you can complete it within two months, it is already amazing!"

Li Fanyu shook his head, "No, it's too slow. It's too late..."

"What's too late?"

"The company's financial situation is very tight now. The promotion period of the used car platform has not passed yet. Although there is income now, it can only barely maintain the company's expenses. The production line at the branch has entered the debugging stage. Every day, money It's like water. If it hadn't been for several bank deposit car modification orders recently, the company would have been unable to make ends meet. The A4 must enter the mass production stage within three months, otherwise this project will bring down the entire company. ”

An Ning has been focusing on the laboratory recently, and Li Fanyu has never told her about the company's operating conditions.

Now that she learned that the company was in such a critical situation, she couldn't help but get red eyes - not because of the company, but because she felt sorry for Li Fanyu.

"It turns out that he is under so much pressure that he still looks like he is laughing and joking every day."

An Ning stretched out her arms, held Li Fanyu in her arms, and rubbed his head with her cheek: "Silly brother, let's fight together."

Li Fanyu’s face was buried in a pair of soft jade rabbits, arched like a pig.

"Well... give it a try!"

……

That night, an article was published on the homepage of Pinche.com - "Zhengxin's first B-class car underwent a wind resistance test today, and its ultra-low drag coefficient ranks among the best in the field of B-class cars!"

Under the headline, right before your eyes is a drag coefficient tester, it is clearly marked - 0.23!

The background of the picture is a somewhat blurry blue car body. Although it is not clear, the beautiful lines still arouse the admiration of many people.

A group of Li Fanyu's **** followers on Pinche.com naturally showered them with flowers and congratulations, and by the way, this news gained a lot of popularity.

As soon as the article came out, it immediately caused reprints on major websites and media. Although this is only a 1:1 scale model, the details cannot be seen clearly. But after the article spread, it still caused a huge response.

In a short period of time, netizens who follow cars knew that Zhengxin was building a car again. Moreover, this time it is still targeting the B-class car market!

To say that the previous reputation of Zhengxin was established entirely because of ZGX888 and X-power. But of these two products, one has just been installed on some models and has not yet been offline for people to experience. One is a high-priced sports car that ordinary people cannot afford to experience.

So the support and attention for Zhengxin is more due to the pursuit of national brands.

But this time the B-class car is different. It is something that can enter thousands of households. So while everyone was paying attention, they also felt a sense of expectation.

It’s not just netizens who are paying attention to this matter. As soon as the news was released, it attracted the attention of several well-known car companies.

Without exception, these car companies have their own best-selling models in the B-class car market. (To be continued.)
