Zhang Yifei had no objection to Prost's arrangement. Although he was confident in challenging the rainy track, many things were not as strong as confidence, and sufficient preparation was the basis for defeating everything.

Alaisi started from the repair station and started to conduct technical inspection circles. Zhang Yifei, Kossell and Alaisi competition engineer Cod, both stood in front of the P-room circular screen, listening to the track feedback sent by Alaisi.

Today's rainfall is considered to be heavy rain at the beginning, but by the time of the formal practice competition, it is almost the standard for moderate rain.

The F1 race is not held at all levels of rainfall. If you really encounter exaggerated rainy weather, the rainfall exceeds the displacement of the heavy rain tires, in order to ensure the safety of the drivers, the F1 official will also choose to stop or end the race early.

Therefore, the upper limit of f1's tolerance for rain battles is the way heavy rain looks.

However, as the safety guarantees for drivers became more and more stringent, the standards for racing on rainy days also decreased repeatedly, and the rain battles that can be seen even dropped from heavy rain to moderate rain.

Because the formal competition is not only the risk of side slipping, but also the water mist splashing in front of the car during the journey. Moreover, at high speed, the car in front of the car can drive out an exaggerated effect like an air cover. The visibility of the car following behind is extremely low, which makes it feel like driving in super fog.

Except for the red warning lights that will light up at the rear of the car in front, it is slightly closer, and even the outline of the car in front cannot be seen clearly.

Think about the foggy weather. The foggy weather regulations stipulate that when the visibility is less than fifty meters, the speed must not exceed 20 kilometers per hour.

For f1 racing, if you drive at 20km/h, then you are just making trouble with me? At least you have to increase the speed ten times to be worthy of the title of the fastest race on earth.

Especially in the initial stage, the water mist brought by the wheels was not even able to capture several racing cars. In addition, the speed of more than 200km/h is more than 200km/h, this control ability has exceeded the limit of human beings. Even F1 drivers cannot avoid the collision of racing cars.

So the Rain Battle, in a sense, is the most intense and exciting event in F1. It’s just a pity that such exciting scenes are rarely seen in later generations. After all, all the exciting scenes are the riders who use their lives to wander on the edge of losing control.

“How is Bridgestone tire performance?”

Cod asked Alessi, the most important thing about F1 racing on rainy days is naturally the grip and drainage effect of the tires.

After 2007, f1 implemented an exclusive agreement for tire suppliers, and all fleets used tires from the same brand.

But at this stage, there are two tire suppliers in the f1 paddock, namely Bridgestone, the "newcomer" who entered f1 in 1997, and Michelin, a veteran tire supplier.

Bridgestone is a tire brand from Japan. Before entering the F1 supplier in the 1990s, Bridgestone had a relatively large gap with its big brothers Dunlop, Goodyear and Michelin, especially in Europe, the largest tire market at that time, which was completely uncompetitive.

But BridgesGM won the quota of F1 racing tire suppliers with a bid of more than 25 million US dollars per year.

It can be said that bidding for the f1 tire supplier is the wisest choice for Bridgestone in the 1990s. In the past few years as a tire supplier, its brand awareness in Europe has increased from 13% to 34%!

The increase in popularity naturally led to an increase in sales, making Bridgestone the world's largest tire manufacturer.

However, at this stage, Bridgestone's trust is still not as good as the old Michelin, so Cod first asked Alessi, how is Bridgestone's rain tire performance?

“The drainage is very good and has good grip.”

Alaisi's feedback came, and everyone at the repair station nodded subconsciously. Bridgestone tires could still withstand the test of rainy days.

After all, Bridgestone not only supplies Prost teams, but also two top teams, McLaren and Ferrari, and has won many team championships. This year's new formula rain tires will naturally not be much worse.

After verifying the drainage performance of Bridgestone rain tires, the circular screen of the repair station began to show that Alessi was increasing his car speed.

Watching the numbers on the screen jump, Zhang Yifei felt very wonderful. You should know that he was the driver on the track before and rarely had the opportunity to stay in the repair station and watch the racing data of other drivers. Today, in a sense, is the first time.

"The high-speed cornering tires are a little slippery and have insufficient grip. The front and rear air wing angles need to be adjusted to the maximum."

The fixed air wing on the f1 racing car is the most important part of the aerodynamic package, which is responsible for adjusting the downforce and resistance of the racing car.

Dingfeng wing is a scientific name. In a more popular way, it means that you see many cars at the tail ends on the road, and the modified exaggerated large tail wing. In other words, this large tail wing can be called the rear fixed wind wing.

The downforce generated by the fixed wind wing is proportional to the resistance. The smaller the opening angle, the smaller the downforce generated, and the smaller the resistance when the car is moving forward.

If the drag is reduced, the acceleration and maximum speed of the car will naturally increase. However, the side effect is that the car lacks downforce, resulting in insufficient stability. Especially when cornering at high speeds, it is easy to get out of the track without grip.

On the contrary, the larger the angle of the fixed wind wing, the greater the downforce of the car, so that it can turn corners at a fast speed, but the speed will be much slower when it comes to speeding up and straight-line extreme speed.

At the same time, the increased downforce will also cause severe tire wear and increase the number of tire changes when entering the station.

Therefore, all the adjustments in F1 are a science, the matching of racing gears, how big the angle of the fixed wind wing should be, tire selection, etc., all require precise calculations and track feedback to obtain the optimal result.

"The rain has cooled down the racing car, so you can consider using small-sized brake vents and engine cooling vents."

Another track feedback from Alaisi came, and the suggestions given this time were more professional, and even changes that Zhang Yifei had not thought of.

You should know that when the angle of the fixed wind wing is maximized, the resistance faced by the racing car will be the greatest, and the rainy day factor will inevitably affect the speed of the racing car.

The small-sized brake ventilation duct and engine cooling ventilation duct can not only prevent rainwater from entering these pipes, but also reduce air resistance. Ordinary new drivers will not think of changing the internal parts of the racing car. Alessi's experience as a veteran is highlighted.

"I've written it down, you're ready to enter the station."

Kossel replied to Alessi, he had run a technical inspection circle for several laps, and after entering the station to adjust, he began the next stage of the timing circle.

After saying this, Kossel turned around and issued instructions to the team technician team, asking them to follow the track feedback of Alessi as fast as possible to help Zhang Yifei's racing to adjust and change.

At the same time, Kossel also looked at Zhang Yifei and said, "Fei, prepare for the technical testing circle."

“Ok.”

Zhang Yifei nodded and responded. He pulled up his racing suit and jacket, then put on his mask and helmet, and walked towards the racing direction.

In an instant, a sultry feeling hit Zhang Yifei. The hot and humid weather in Malaysia is really not very friendly for F1 drivers wearing heavy racing suits.

This kind of minor adjustment is simply a slight meaning for the professional technicians of the F1 team. Just when Zhang Yifei was wearing these racing equipment, the adjustment was completed, waiting for Zhang Yifei to drive onto the track.

He sat inside the racing car and inserted an ignition device at the rear to start the racing car. Just as Zhang Yifei was about to push his mask down, Ahu from the parking space seized the time and asked Zhang Yifei, "Brother Fei, be careful on rainy days."

Looking at Ah Hu's slightly nervous look, Zhang Yifei smiled at him, and then said, "Don't worry, do you still have no idea about your brother Fei's ability? If it were twenty years ago, there would be no such thing as Senna in the rain, and only Zhang Yifei in the rain will be left!"

Seeing Zhang Yifei's moments and still feeling bragging, Ah Hu's inner tension also eased a lot.

With a "bang", close the helmet mask, then release the clutch and step down the accelerator. The engine speed began to increase instantly. The car quickly drove away from the repair station and entered the repair channel.

The team members were not idle at this moment and rushed to the repair parking space outside the P room. Because at the entrance of the repair passage, Alaisi's racing car had already driven in, and he was about to enter the station to adjust.

As soon as he entered the maintenance passage, Zhang Yifei felt that he was different from his previous driving. The most direct point was that raindrops fell on the helmet, forming water marks.

Even though the helmet has been sprayed with water repellent in advance, there is still no way to completely avoid the traces of water droplets. These falling raindrops have greatly affected the driver's vision and attention. Zhang Yifei must overcome this interference.

The problem is that the water droplets outside the helmet have water repellent protection. The fog inside the helmet is a bit difficult to solve. This feeling is like driving after rain in winter or summer, and the glass in the car window fogs, which is a factor that seriously affects sight.

The inner layer of glass of the f1 helmet actually has many special coatings to prevent fog. In addition, the racing fire hood can also play a role as a mask to a certain extent to prevent fog inside the helmet.

But even with all kinds of measures, just like falling raindrops, there is no way to completely solve this problem. Zhang Yifei also needs to overcome it quickly.

Of course, this is not the first time that fogging occurs. There have been many during the winter test period. Zhang Yifei has become accustomed to it. It is just a combination of raindrops and water marks to interfere. This is the first time Zhang Yifei has, which requires some adaptation time.

So after the maintenance channel was released, Zhang Yifei's speed did not open very quickly, and the technical inspection circle was slower than the previous Australian station.

But not long after he drove onto the track, a car whizzed past him, and the mist splashed was overwhelming. In an instant, Zhang Yifei saw a vast white area in front of him.

This feeling is like a water puddle on the side of the road when it rains. You are walking slowly. A car is driving by at high speed. The water droplets splashed on the tires directly pour you into a chicken.

Although Zhang Yifei knew that such a thing was inevitable, is it necessary to overtake so closely in the practice competition technical test circle?
