Riding a Kawasaki H2 to chase the high-speed rail, the school beauty was moved to tears

This design is quite subtle, and Qin Chuan was worried about this issue before.

The company that is currently the most advanced in this type of small wing fixed wing is Ducati. This is Ducati's own creation, and the following major car manufacturers have all imitated it.

Ducati's small wing is slanted and is located on the rear of the car, behind the seat, not the swing arm.

Ducati's small wings are also called dinosaur tails because their shape is not like the left and right ones of an airplane, but is slanted like the spikes on the back of a dinosaur.

The front can generate downforce, and the side can generate cornering stability. Neither of them is particularly prominent, but both aspects are extremely balanced and will not affect each other. This is the most difficult thing to achieve.

KTM also has similar small wings here, but the shapes are different and they are frequently changed. Qin Chuan has a deep understanding of this. When testing at the end of last year, he tested small wings of various shapes, all of which were arranged behind the seats.

The reason is that it is impossible to take both curves and straight lines into consideration, so the fixed wings here actually need to be improved every year.

The solution he chose in the end was only relatively good, not as perfect as Ducati's. As for copying it directly? No, because the overall streamline of the car body is different. In short, it's useless to copy it if it doesn't match.

Now this small wing has barely solved this problem. No wonder it is only four centimeters long. It turns out that it was made with the cornering in mind.

Qin Chuan was not blindly optimistic. The four-centimeter small wing could generate some downforce, but definitely not much.

“If you can improve your speed by 1km, it’s considered good progress. Don’t expect too much.”

After ending the call, Qin Chuan said lightly.

On a one-kilometer straight line, the speed difference between the KTM and Ducati is actually only a few kilometers. Being able to narrow the speed gap of even one kilometer is already a significant improvement.

After closing the computer, Qin Chuan was about to lean back and take a break when he suddenly heard a woman's voice in his ears.

The woman's voice was so loud that almost the entire first-class cabin could hear it.

Qin Chuan and Jiang Yue frowned slightly, as if they felt that this voice should not appear in the first class cabin.

You have to know that even when Qin Chuan was speaking just now, he was speaking in a low voice, and even avoided not speaking at all. He was just listening. After all, it is not good to affect others.

But at this moment, the woman's noise was so loud that even people in the next cabin could hear it clearly.

"Are you kidding me? I'm sitting in first class, and you're giving me a shabby chair. I want the same chair as that woman just now. Go find a way for me."

The voice came from the row of seats in front of Qin Chuan, and on the side opposite Qin Chuan.

It was at an angle to Qin Chuan's seat, so Qin Chuan could just see it. This was also the only seat they could see.

The other party was a slightly plump young girl with a pair of round glasses on her nose. At this moment, she was arrogantly following the stewardess to ask for a stool.

It is worth mentioning that she was not the owner of this seat. Qin Chuan did not remember there was such a person in the first class cabin when he boarded the plane.

If he remembered correctly, this seat should be occupied by a man. At the moment, there was another man in that seat, who was equally young and dressed even more mysteriously than Qin Chuan. Even in the first class cabin, he still wore a mask and sunglasses, covering himself tightly.

Looking over, Qin Chuan saw him. Yes, it was this man. He was the owner of this seat.

Jiang Yue's pretty brows frowned slightly, and she went back to her original position, retracting her hand that was on the chair.

She had just heard the girl's voice, but didn't say anything for fear of disturbing Qin Chuan.
