Shangluo remembered this step. Because except for locals like them, other schools have to practice on the road. The roads are not closed during practice, but are guided by guided vehicles. The vehicles of each team run around a week in advance and stop as usual if there are traffic lights in the middle.
"I practiced last time. The next practice is Sunday the day after tomorrow, and it is also the last practice. Next Sunday is the end of the South Zhili qualifiers, and then the next Sunday is the intensive training of all teams across the country. Next Sunday This week is probably the day of the finals, which is around the end of August or beginning of September. The specific date depends on the weather. How are you, are you sure?"
"Easy. But we all have Zentraedi-like skills. Do other teams still have the fighting spirit?"
"Tsk, let me tell you, the other teams are not vegetarians either." She lowered her head and glanced at her watch: "Yes, it's about to start."
"What's about to start?"
Before he finished speaking, Shangluo heard a "buzz buzz buzz" sound, which made his back feel cold. This was the sound of the two ramjet engines on the Ninghe. It's not that big, but it's close, almost next door.
The low roar shook his eardrums. If he didn't have the physique of a heavenly being now, he would probably want to vomit
A formula racing car slowly drove out from the garage next door. The vehicle's engine did not start, but the rocket nozzle on its back pulled out a short tongue of flame.
"What's going on???"
"Rocket. The Rocket of Wuhu Rockets, a team that represents South Zhili throughout the year, sponsored by Army Airlines. The cockpit is the same as ours, and the ramjet engine on the back is a serious rocket engine."
"Is it the rocket car I mentioned before? It's really coming!"
"You can see it every year, and it's different every year. Have you noticed that the air intake is trumpet-shaped, with a convergent tail, and is equipped with a turbine fuel pump. As long as the ignition is started, the fuel pump will be driven to continuously inject kerosene. Come out and ignite. That rocket, like their engine, uses aviation kerosene. So their fuel injection pump is specially made and the fuel injection speed is faster than ours."
While he was talking, the car had already reached the starting point and turned off, keeping silent and preparing to start. However, the crew next to them did not move away, but instead held larger equipment - when the engine was turned off at the starting point, someone checked their watch: "Ready, three, two, one!"
A whistle blew, and the crew with equipment rushed to the side of the car, divided into two teams, front and rear. The front team member is a big man nearly two meters tall. He holds a huge turbine blower aimed at the silent air inlet and pours high-pressure gas into it. The rear team uses a spray gun to aim at the tail and prepares to ignite it.
"They are igniting the fire." Qi Yuan explained, "The weight of the ramjet rocket has been reduced to the extreme. It is a double-layered stainless steel nozzle, which is lighter than the tail fin, so as not to affect the normal operation of the vehicle. Less It's so heavy that it can't start on its own, so it needs an additional starting group - air is injected from the front, ignition is done at the rear, and at least the fuel pump turbine is started."
As he spoke, the rocket resumed its buzzing roar.
"7 seconds 5." When the timer ended, the driver turned off the engine again and drove the car back.
"Have they been practicing this?" Shangluo asked.
Qi Yuan nodded: "Because this is an extra step, it requires extra practice. Because the total number of people in the team is limited, they need to draw people from other places in order to order this rocket. 7.5 seconds is not too slow, because The average time is about 6 seconds. They are already very good at this time, but it is easy to lose focus when it comes to competition."
"Is this still the case?"
"It happened last year. It misfired during the finals. The rocket couldn't ignite on its own, so it had to go back to the maintenance station. It turned out that it misfired again. It was so miserable. I even wondered if it had been demoted. Why did it hit us? I ran like a rocket when I was there, but I fell apart when I entered the finals.”
"Any other home rockets?"
"Some people have used it before, but the only ones who insist on using it are the Rockets - it is very suitable from the track point of view. This is a kind of 'ultimate move', and the competition system leaves a lot of room for these strange styles. There is room for development. Let me give you a general introduction to the track: Yujing Circuit has a super long straight-line acceleration section, which is the road leading to the racing track. During the competition, you can see them rumbling from the ground like a rocket. It rushes from a distance and then disappears in the blink of an eye. The remaining curves are very narrow, making it difficult to overtake."
"Ah, so as long as they rush to the front at the beginning, they won't be afraid of overtaking even if their performance is a little worse in the corners?"
"Yes, and after running in a straight line, they will burn a lot of fuel, but they will become lighter, and the speed will not drop much. After being passed by them on the straight line, it is easy to get stuck in the corners. But their biggest problem has always been It’s about refueling. After our car uses a continuously variable transmission, the most powerful thing is its fuel economy. When Wenyuan tried driving last time, he only needed two stops to finish the race. The second stop only required half of the fuel, and he could save fuel out of thin air. It weighs dozens of kilograms. And this rocket car starts with four stops, and when the battle is fierce, it can even finish with five stops."
"But can you win?"
"Yes, although five stops is very troublesome. But after precise calculations and practice, they have a great chance of winning - this is formula racing, which is essentially solving problems. We are all looking for the optimal solution to the same problem. Although the Rocket is not easy to run on other tracks, it is a special solution to the characteristics of the Yujing track. Of course, they are probably out of business this year, because the Tiandao Shadow Puppet has completely surpassed it in performance. Because the curves are fast, they are really fast! The Tiandao Shadow Puppet is not slow on the straights, but the curves are ridiculously fast with the help of active suspension and continuously variable speed. The little distance they open on the straights, just a few corners He was surpassed by Wen Yuan."
"Oh~~That said, I'm quite confident."
"But it's not over yet." Lu Liang shook his head, "There will be additional questions during the competition."
"Is there an additional question? What is it?"
"After all, it's called an equation, and it means solving equations. Just solve the problem. How can you know the test questions before the exam starts. The Yujing Circuit only gives a range of questions, and the questions will only be announced six hours before the start. Sometimes the race schedule is extended or shortened, some refueling is prohibited, and sometimes a safety car is added after the start of the race to suppress the speed of all cars. The Rocket was directly crushed to death when it hit the safety car, because the Rocket was also idling. It needs to burn oil to maintain the operation of the fuel pump. And what we are playing is a contingency. The Tiandao Shadow Puppet's adaptability is impeccable, and it can easily deal with any problem. General solution, this is our way of solving problems. "
