Shang Luo remembered this step. Because except for locals like them, all the other schools have to practice on the road. During the practice, the road was not closed, but there was a guide car with it, and the vehicles of each team ran a circle about a week in advance, and the traffic lights in the middle stopped as usual.

"I practiced last time, and the next practice is the Sunday the day after tomorrow, and it will be the last time. Next Sunday is the end of the South Naoli Qualifiers, and then next Sunday is the concentrated practice of the national teams, and next week is probably the day of the finals, that is, around the end of August and the beginning of September, the specific date depends on the weather. How, are you sure? ”

"It's easy. But we've all come up with Zenith-like skills, do the other teams still have fighting spirit? ”

"Tsk, let me tell you, the other teams are not vegetarians either." She glanced down at her watch: "Yes, it's about to start."

"What's going on?"

Before the words fell, Shang Luo heard a "buzzing buzz", and he heard a chill behind him, which was the sound of the two ramjet engines on the Ninghe. It's not that big, but it's close at hand, and it's almost right next door.

The low roar shook his eardrums. If it weren't for the fact that he had the physique of a celestial man now, he would probably want to vomit

A formula car slowly drove out of the garage next door. The on-board engine did not start, but the rocket vent on its back pulled out a short tongue of fire.

"What movement ????"

"Rocket. The rocket of the Wuhu Rocket Team, the group that appeared on behalf of Nanzhili throughout the year, was sponsored by Army Airlines. The cockpit is the same as ours, and the ramjet engine on the back is a serious rocket engine. ”

"Is that the rocket car I talked about earlier? It's really coming! ”

"I see it every year, and it's different every year. You notice that the intake duct is flared, the tail is convergent, and it is equipped with a turbo fuel pump. As soon as the ignition starts, the fuel pump will be driven to continuously inject kerosene to ignite. That rocket, like their engine, was made of aviation kerosene. So their oil injection pump is specially made, and the oil filling speed is a bit faster than ours. ”

As he spoke, the car had already driven to the starting point and turned off the engine, keeping silent and preparing to start. However, the group next to it did not withdraw, but instead held a larger equipment - when the engine was turned off at the starting point, someone pinched the watch: "Ready, three, two, one!" ”

A whistle sounded, and the car crew with the equipment rushed to the side of the car, divided into two teams. The front team is a large man who is nearly two meters tall, holding a huge turbine fan and aiming it at the silent air intake to fill it with high-pressure gas, and in the back is aiming the spray gun at the tail to prepare for ignition.

"They're igniting a fire." Qi Yuan explained, "The ramjet rocket has been reduced to the extreme, it is a double-layer stainless steel spray canister, which is lighter than the rear wing, so as not to affect the normal operation of the vehicle." Reducing weight to such a point that there is no way to start on its own, so it needs an additional starter group - air in the front, ignition at the rear, and at least the fuel pump turbine up. ”

As he spoke, the rocket resumed its "buzzing" roar.

"7.5 seconds." When the timer was over, the driver turned off the engine again and drove the car back again.

"Have they been practicing this?" Shang Luo asked.

Qi Yuan nodded: "Because this is an extra step, it requires additional practice." Because the total number of people in the team is limited, they need to draw people from other places in order to light this rocket. 7.5 seconds, which is not slow, because the average time is about 6 seconds. It's already very good for them to practice this time, but it's easy to not catch fire when they really get into the game."

"Is this still the case?"

"Last year, it was a dumb fire in the final, and this rocket couldn't ignite on its own, so it had to go back to the maintenance site. As a result, it was dumb again, and it was too miserable. I wonder if we were downheaded, why we ran like rockets when we beat us, and dropped the chain when we reached the final. ”

"Is there another domestic rocket?"

"I've had people use it before, but it's only Team Rocket that sticks with it – it's a good fit for the track. This is a kind of 'ultimate', and the competition system leaves a lot of room for these Qimen to play. Let me give you a general introduction to the track: the Yujing Circuit has a long straight-line acceleration section, which is the road that leads to the racetrack. During the game, you can see them rumbling from afar like rockets, and then disappear in the blink of an eye. And the rest of the curve line is very narrow, making it difficult to overtake. ”

"Ah, so as long as they rush to the front at the beginning, they are not afraid to overtake even if their performance is poor in the corners?"

"Yes, and they burn a lot of fuel after running a straight line, but it's lighter, and it doesn't slow down much. After the straights are overtaken by them, it is easy to get stuck in the corners. It's just that their biggest problem has always been refueling, and after our car uses a continuously variable transmission, the most powerful thing is fuel economy. When Wen Yuan tested the car last time, it only took two stops to finish the race, and the second stop only needed to bring half of the fuel, which could reduce dozens of kilograms out of thin air. And this rocket car starts with four stops, and even five stops when the battle is fierce. ”

"But can you win?"

"Yes, although it is very troublesome. But after careful calculations and practice, they have a big chance of winning - this is formula racing, which is essentially solving problems, and we are all looking for the optimal solution for the same problem. Although the Rocket is not easy to run on other tracks, it is a special solution given for the characteristics of the Yujing track. Of course, this year, they are estimated to be out of play, because the Tiandao Shadow Puppet has achieved a comprehensive surpass in performance. Because the curve is fast, it is really fast! The Shadow Golem isn't slow on the straights, while the corners are ridiculously fast with the help of active suspension and continuously variable gear. The distance they opened up on the straight, a few corners were overtaken by Wen Yuan. ”

"Oh~~ I'm quite confident when I say that."

"But it's not over yet." Lu Liang shook his head, "There will be additional questions during the competition." ”

"And an additional question? What is it? ”

"After all, it's called an equation, it's to solve equations, and you know the exam questions before the exam. The Yujing track only gives a range of questions, and the questions will be announced six hours before the start. Sometimes the race is lengthened or shortened, some are banned from refueling, and sometimes even a safety car is added after the race to speed all the cars at once. The rocket was crushed to death immediately after hitting the safety car, because the rocket also burned oil to keep the fuel pump running at idle. And we, playing a strain. The Heavenly Dao Shadow Puppet's adaptability is impeccable, and it can easily deal with any problems. That's how we solve the problem. ”
