"This js53 racing car adopts a new generation chassis architecture, with a wind resistance coefficient of nearly 0.05 lower than the previous generation. However, the wind tunnel optimization of the front and rear fixed wings ensures that the car can still ensure sufficient downforce while driving at high speed."

Charlie began to explain to Zhang Yifei about the aerodynamic layout principle of the racing transformation so that he could better understand the new racing car he was about to drive.

You should know that the most important part of F1 racing is about aerodynamic design. Each F1 racing car requires many wind tunnel tests from research and development to finalization, which is also one of the most expensive parts of racing development.

Moreover, it is not just about wind tunnel testing, but building wind tunnels is not cheap. The cost of a wind tunnel is about 60 million to 100 million US dollars. This high price directly dispelled the idea of ​​many fleets entering F1.

After all, the standard for burning money is here, and each of them is spent hundreds of millions of dollars. Not to mention competing with other teams on the track, even the "basic installation" cannot be collected. What's the point?

Therefore, in order to reduce the entry standards for the F1 fleet in later generations, the FIA, announced that the two fleets could use a wind tunnel together and use a "sharing" method to reduce expenditures.

This idea is actually correct, but it’s a pity that the F1 technology content in later generations is too high, and it can no longer be solved by a shared wind tunnel. A small team or a private team with no money is not a match for a large manufacturer at all. Mercedes-Benz’s winning rate is as high as 80%, which also shows that the balance of the event has actually been broken.

But in this era, it is still in an era of heroes competing for hegemony. Even the strongest Ferrari, other teams have not cut off their confidence in challenging it. Even the bottom teams, such as Prost and Minardi, have not chosen to give up accepting their fate.

"This time the chassis adopts a sandwich structure, with honeycomb aluminum plates in the middle and carbon fibers in the outer layer. However, the carbon fiber material has sufficient rigidity but not enough toughness. So we injected epoxy resin before the carbon fiber outer plate was formed to ensure the combination of rigidity and toughness of the entire chassis."

Listening to Charlie's explanation, Zhang Yifei kept nodding seriously. Because he knew that the quality of the chassis would determine the handling of the entire race car, and more importantly, it would also determine the safety after the accident.

Therefore, the chassis of the F1 racing car is as lightweight as possible and can be strong enough. In this way, the driver's life safety can be guaranteed in the event of an accident.

"In terms of racing power, we use the 3.0lv10 engine developed by the new generation of Peugeot in France. Due to the high failure rate last season, Peugeot reduced the power output to 890p horsepower this time, and the maximum speed is 19,000 rpm."

The Prost team had a finishing rate of less than 30% last season, and drivers withdrew from almost every game, and most of the reasons were racing engine failures.

This fierce record has put a lot of pressure on Peugeot. Previously, 930p horsepower almost drained the engine's potential, and engine failures such as cylinder explosions are likely to occur.

So in order to enhance stability, they adopted a less extreme engine setting this time, reducing the maximum horsepower and fastest speed, to prevent the Prost team from repeating the tragedy of last season this year's F1 season.

But when he heard this parameter, Zhang Yifei frowned. Before 2006, Fia had not limited the number of cylinders to 8 cylinders and the displacement was not limited to 2.4l. The power was actually an upward trend. Many F1 engines had actually exceeded a thousand horsepower.

According to normal logic, in order to ensure stability, Peugeot should not reduce even if the horsepower is not increased. Can this behavior of driving and reversing be regarded as a "new generation of R&D" event engine?

Zhang Yifei was very confused, but he didn't say it, because if it weren't for a special stunt, the 890 horsepower of the F1 car was actually enough.

It’s like the limit speed of the F1 car exceeds 400km/h, but in fact, on the track, it’s already considered the highest speed of the F1 to run to 360km/h, and it can only drive such a limit speed on a very small number of specific track sections.

So this is just Zhang Yifei's inner guess. It's not good to really say that there is something wrong with the Peugeot Engine. If you don't understand professional things, it's best not to make a conclusion, at least you have to wait until you have tested it before you can get the answer.

Charlie next introduced several pneumatic components to Zhang Yifei, the most important of which are the racing chassis height, etc.

The height of the racing chassis is actually where the F1 team has been seeking a balance point. Theoretically, the lower the chassis, the better, so as to minimize the lift caused by air passing under the chassis.

There is a famous saying in aerodynamics, which is "powerful and flying bricks". In fact, compared with the power and weight of the F1 racing car, as long as the body and aerodynamic kit are not designed well, you can directly lift the front of the car by stepping down the accelerator.

Therefore, the f1 aerodynamic design emphasizes downforce as much as possible and puts the chassis to a minimum.

However, the problem this brings is that when you make a big turn, there is a chance that what we usually call "bottom-bottom" will occur.

In the F1 races in the 1980s and 1990s, you can often see the car flying the bottom on the track due to the bottom. Even when the Senna curve was accidental, I suspected that the reason for the insufficient steering was later suspected. In addition to the problems of the speed and steering mechanism, there was also the bottom.

Later, in order to ensure the safety of drivers, the FIA ​​also imposed a minimum height limit on the chassis height of the car. However, during the racing process, as the tire loss or tire pressure decreases, the racing height will actually gradually decrease in the later stage.

Therefore, setting the chassis height is also a very complicated issue, and different judgments must be made based on the track conditions and driving time.

The reason why f1 has become the most technologically tech-friendly event on the earth is that it is that it is believed that the requirements for technology in any aspect have reached the extreme!

After the performance explanation of js53 racing is completed, the next step is the test stage. However, the first round of tests was not Zhang Yifei, but the team's veteran Alaisi conducted the first test.

Because Alaisi has been a veteran for more than ten years and is very familiar with the winter track venue. He can report racing issues as soon as possible and make the best adjustments.

Zhang Yifei had no objection to this. Although he thought he was not very modest, he definitely had a name in the f1 paddock, and he was the identity of a newcomer and rookie.

For areas that you are not good at and understand, it is the truth to look at and study hard!

JS53 racing is about to start the track test, and Zhang Yifei and Kossel stand outside the repair station in advance, because some early teams on the track have already started their own winter test.

Zhang Yifei's goal is naturally to Schumacher. He wanted to see what kind of lap speed Schumacher could run on the winter test track at his peak. In this way, he would have a reference standard. I dare not say that he can surpass Schumacher's speed, at least not fall too much.

But unfortunately, the Ferrari team has not started testing on the track. The three teams of Renault, McLaren and Minardi are testing in the winter.

Although Ferrari has not started winter testing, McLaren is also a wealthy family among these three teams, so Zhang Yifei quickly turned his attention to McLaren. However, now they are all test cars, and driver numbers are not printed on the body, so Zhang Yifei doesn't know who the specific driver is.

"Little guy, I didn't expect to see you in the f1 paddock so soon."

A familiar voice came from behind. Zhang Yifei turned around and found that Nicky Lauda was standing behind him, looking at him with a kind smile on his face.

"Hello, Mr. Lauda."

Zhang Yifei asked politely. Nicky Lauda is not only his predecessor, but also a legendary driver of F1. Respect is a basic etiquette.

"You don't have to be so polite. When I saw you at the Nürburgring, I felt that you had great potential. But you improved faster than I thought. You signed with Prost team from Renault's junior driver in a few months. Today I saw you on the winter test track. It really made me feel that young people have great potential."

In addition to praise, Lauda's tone also had a hint of regret. After all, he had already seen Zhang Yifei's potential at the beginning. However, the faction within the Jaguars was too complicated. The "old" faction of the European Stewart team and the American parent Ford Party were extremely difficult to fight. Any important decision would be hindered.

Under such circumstances, it is easy to imagine how difficult it is to sign a pure newcomer like Zhang Yifei to become a team driver. So Lauda finally had to miss it regretfully, and then watched Zhang Yifei grow step by step, from an unknown newcomer of Formula Renault to today's F1 driver.

"Mr. Lauda, ​​you are too proud. It's better to praise me now. At least after I win a few championships, I'll have a lot of potential."

When Lauda heard Zhang Yifei's words, he felt humble at first, but soon he understood another meaning in his words. The Chinese boy is now thinking about winning several championships.

But it is normal to think about it. If Zhang Yifei did not have this confidence and spirit, he would not be able to stand out from the Renault Formula, and he would not be able to gain a foothold in F1.

"Very good, then I'll see if you win the championship first, or if another talented newcomer on the track now becomes the championship first."

“One other on the track?”

When Zhang Yifei heard this, he was a little confused about who the other one was? But he soon remembered that after Kimi Raikkonen was selected by Sauber, he jumped into the Big Three team McLaren the next year and became their official driver.

And this season, Kimi began to show his amazing talent. With McLaren, which is not the leading performance, he became the sixth in the driver's standings. Unfortunately, Kimi's best result was second in the branch and did not win a championship title.

At this time, Zhang Yifei looked at McLaren on the track, his eyes a little confused. He didn't expect that he had become a talented newcomer tied with Kimi. It seemed like the trembling of ice and fire in history, he might stage a Gemini battle with Kimi in advance.

"Mr. Lauda, ​​I wonder if you have seen an interview with me before."

“What interview?”

Nicky Lauda shook his head, he was not interested in these media interviews.
