With the help of the three giant gods Max, the construction of Xingshan was finally completed within a month, and with the connection of the two reserved cloud rails in the north and south of Xingshan, which lasted nearly 10 months, the "Jingxiang" cloud rail was officially announced!

Now, it's just the last step – the opening experiment.

Ma Tian also returned to the City of Progress and began to plan the final opening experiment.

The first is how to modify the cloud car, so that the cloud car becomes the "Jingxiang No. 1" for loading, and to have a "derailment function", the previous two water drop shapes are definitely no longer suitable.

Ma Tian discussed with the engineer for a long time, and finally decided to change it to the shape of a spire bullet, which roughly looked like a bullet hollowed out in the middle, constantly overlapping each other.

Each section of the bullet can be continuously inserted into the bottom of the previous bullet, so that if the last bullet is detached, the overall shape will not change, but the length will be shortened a little.

The appearance structure is determined, and the rest is how to design the inside to be easy to load, or how to load people.

Although this experiment is loading, considering the more difficult manned experiments in the future, Ma Tian still thinks that it is better to consider manned now.

So, Ma Tian still worked with the engineer to install the seats inside, and then considered what the people in the car would carry, such as suitcases, school bags, etc.

The current suitcase must not be placed randomly like on the high-speed train, and must be placed in a special cabinet to prevent it from running around.

Even each seat should be equipped with a strap to prevent people from running around. The acceleration of the cloud car is so fast, it is not possible for passengers to move around casually like taking a high-speed train, and they must always be in the seat, just in case.

It's not that you can't do anything, after adapting to acceleration, it's still okay to drink milk tea and water, and the voice broadcast on the car will be accurate to the second prompt, when to accelerate, decelerate, and when to drink.

For example, in this experiment, Ma Tian specially put hundreds of cups of Xiangshi's unique tea and milk tea on the car and brought them to the staff of the site.

And the one I bought is still hot, according to the plan, when I go to them, the milk tea should still be warm.

I believe that there may be an afterword in the future - it may not be possible for warm milk to ride the cloud car.

If the design drawing of "Jingxiang No. 1" is confirmed, it only needs to be handed over to the corresponding engineer for construction.

Two weeks later, "Jingxiang No. 1" was officially manufactured and delivered from the workshop, and it was steadily stopped in the city of progress at the starting station.

After Ma Tianjin went inside to check for the last time, he began to check the line for the last time, checking the data of early warning cameras and detection instruments installed on various roads, and then scanning the orbit with a satellite in space to see if there were any suspicious people or objects in contact.

Many people may be worried, what if someone deliberately destroys the cloud track after the cloud car is started? After all, the speed of the cloud car is too fast, and it is too late to brake.

In fact, the engineers of the State Construction Commission have raised this question for a long time.

However, they shut up after looking at the material parameters of the magnetoalloy, because the solidity of the magnet alloy can actually resist two tank armor-piercing shells.

If someone wants to blow up the cloud rail with ordinary explosives, it may take more than two hours to blow up the long alloy shell of the cloud rail, and finally face the cloud rail that can resist two tank armor-piercing shells.

2 hours is enough for him to send the White Emperor over to destroy the saboteurs dozens of times.

After the final inspection, Ma Tian also asked the staff at each station to pay attention to the fact that the "Jingxiang No. 1" will start to set off in 15 minutes, and pay attention to the carriages that arrive at the station.

After thinking about it, Ma Tian posted a news of live cloud car on the meager again:

[Jingxiang Cloud Rail will be put into trial operation today, and interested partners can watch it on the official website of Tianyu Xinghai in 15 minutes~~]

It's not that you have to install this wall, the main thing is that Ma Tian wants to prove that he is not lying, and the speed of the cloud car can really reach more than 10,000 km / h.

Ma Tiandu personally posted a meager post, and the popularity naturally didn't have to be said, and the comments and retweets exceeded 1 million in less than a while.

However, Ma Tian didn't pay attention to it, he even felt noisy, and he didn't even open a meager notice.

As 15 minutes passed, Ma Tian was also sitting in the satellite monitoring room, issuing the last start command.

The world's first ultra-high-speed cloud car has started!

At the same time, a special satellite was also transferred to follow the shooting, and now only the satellite can capture the speed of the cloud car, even if the White Emperor goes to follow the shooting.

The official live broadcast room of Tianyu Xinghai was also opened synchronously, and satellite images were imported by Ma Tian.

[I'm number one!] 】

【Grab the sofa!】 】

[Is this a satellite perspective?] 】

The barrage in the live broadcast room also increased all of a sudden, and some people also discovered that this was a satellite perspective.

The satellite perspective is very high-altitude overhead shooting, so the floors and roads are basically squares and lines, and they are easy to recognize.

The audience was also quickly attracted by the accelerated "Jingxiang No. 1".

"Friends in the live broadcast room, hello everyone, the train you see now is 'Jingxiang No. 1'!" Due to the temporary hurry, Ma Tian did not arrange a commentator, and simply spoke in the live broadcast room.

[Who's talking?] 】

[Is the god Ma Tian talking? 】

[It's not Ma Tian, it's my husband~]

……

Ma Tian glanced at the flying barrage and raised his eyebrows, these people can really work, but the movements in their hands have not stopped.

First, the satellite was operated to zoom in on the focus and look at the four big characters of "Jingxiang No. 1" on the train, and then the angle of view was raised to capture the entire train, and the test speed was displayed on the train through the algorithm.

378km/h，386km/h，394km/h……

The speed of the train slowly accelerated at a speed of 8m/s^2, and soon broke through the speed of the high-speed train.

The attention of the audience in the live broadcast room was also attracted by the speedometer of "Jingxiang No. 1".

864km/h… 1200km/h……

[, this is breaking the speed of sound!] 】

Seeing that the cloud car broke the speed of sound in less than 1 minute, netizens who knew a little common sense began to post barrages.

[Isn't it, this is breaking the speed of sound?] How can it be so simple? 】

[Isn't there a sonic boom with a sonic boom cloud?] Why don't I see sonic boom clouds? Some netizens also raised their own questions.

Seeing that many people in the barrage were strange about the sonic boom cloud, Ma Tian also opened his mouth and explained: "

In fact, the sonic boom cloud does not necessarily occur beyond the speed of sound, but also depends on the humidity of the air, etc., strictly speaking, it is caused by a shock wave that exceeds the speed of sound.

In order to reduce the energy effect of this shock wave, I have loaded the cloud car with a 'mirror breaker', which you can understand as a needle that specializes in piercing the sound barrier. Because of the presence of this needle, there will be no sound barrier, and naturally there will be no sonic boom clouds. ”

【Ma Tian Great God Cow Wall~】

[Although I don't understand it, it doesn't prevent me from knowing that Ma Tian is powerful. 】

……

Listening to Ma Tian's explanation, a group of people in the barrage began to change direction again and began to pat Ma Tian's ass.

Ma Tian looked at the rainbow fart of the barrage, and a smile hung on the corner of his mouth, should I say it or not, it feels good to invent a technology and be recognized and praised by most people.

In fact, there are many advanced technologies used in "Jingxiang No. 1", not only this "mirror breaker".

"Jingxiang-1" can break the speed of 10,000 km/h, which is definitely not as simple as the word says.

Take this "mirror breaker" as an example, if there is no such thing, then when the cloud car passes by at supersonic speed, people within a radius of at least 60 kilometers will be affected by the "shock wave" generated by the sonic boom.

For example, the household glass in the house within 3 kilometers of the cloud track will basically be broken, and even some people's ears are a little fragile, and they will directly crack the eardrum and bleed from the mouth and nose.

Within 1 km of the cloud track, if the cloud car happens to pass at a maximum speed of 10,000 km/h, the sonic boom can directly cause people to bleed and die directly!

Another example is the "counterflow hole" structure mounted on the cloud body, which is also very critical.

This "counterflow hole" structure is hidden in the surrounding body of the cloud car, and its function is to reverse the air flow around the cloud car.

We should all know that if an object passes quickly, then the airflow in the place it passes through will also accelerate, which will cause the air pressure inside to become smaller, and the air pressure on both sides to become larger, which is also called Bernoulli's principle.

The simplest experiment is to put two sheets of A4 paper in parallel, and then you blow into the middle, and you will find that the two sheets of paper are adsorbed to the middle.

Let's think about it, if we take the high-speed rail, when the high-speed rail enters the station, there will be staff who tell us not to get close to the yellow line, that is, we are worried that the high-speed rail passing at high speed will produce Bernoulli's principle, so that we will be killed by the past by absorbing the past.

Even the speed at which the high-speed train enters the station has to worry about Bernoulli's principle, and everyone thinks about the cloud car passing by 10,000 km/h.

If there are no these "counter-flow hole" structures, then let alone people standing outside the yellow line, even if they stand 500 meters away, they will be swept up by the cloud car that is speeding by at high speed.

In addition to the "mirror breaker" and "counterflow hole" mentioned above, there are various designs such as anti-heat barrier and anti-sound shell.

Therefore, the technology used in the design of a cloud car may be beyond the imagination of most people in the live broadcast room.

The "Jingxiang Cloud Rail" has a total length of 1,383.7 kilometers, and the first station it passes through is Zhumadian Station, which is 432 kilometers away from the City of Progress.

When the Jingxiang No. 1 reaches a speed of 1,650 km/h, the last carriage begins to disengage on its own, slowing down until it stops at Sumadian Station.

However, the audience in the live broadcast room didn't know about this situation, and they were shocked when they saw that "Jingxiang No. 1" suddenly broke a section.

The live barrage also began to brush up on the screen full of question marks.

Ma Tian had to popularize the "derailment technology" again, so that the audience in the live broadcast room should not worry, this is a normal process, and then deliberately divided a small window and placed it in the upper right corner to track the perspective of the carriage that is going to stop at Zhumadian.

[, Niu Wall, can you still play like this? ] 】

[Sure enough, learning is still useful, like me, who doesn't like to study, I only think of going there to stop and then accelerate.] 】

……

The live broadcast room was once again shocked by the design of the cloud car, and it turned out that it could save time in this way.

Now the cloud car has become 2 parts, the cloud car of the main track is still accelerating, and the cloud car of the track to Zhumadian is constantly slowing down.

At this moment, you can intuitively feel the braking distance of the cloud car compartment deceleration, even if it is only 1650 kilometers of deceleration, the braking distance is more than 13.1 kilometers, and the deceleration time is more than 1 minute.

1 minute later, the detached carriage successfully arrived at Zhumadian, representing the success of the first stage.

The members of Zhumadian successfully got a specially designed "Beijing-Hunan Cloud Rail" train souvenir from the carriage, as well as Xiangshi's tea and pleasant milk tea.

Ma Tian simply directed the selfies they sent and the performance of the cheering engineers to the live broadcast room.

"The experiment has been completed at Sumimadian Station~"

[Congratulations! 】

[Tianyu Xinghai Cow Wall, National Cow Wall! ] 】

……

The live broadcast room also played a piece of congratulations and blessings, as well as praise for the cloud rail construction unit.

The cloud car on the main track is still accelerating, and its speed has reached an astonishing 5046 km/h just after a dozen forks.

Now, even from the satellites, you can see that it is moving forward at an alarming speed.

Ma Tian also knocked on the code and guided the camera scene inside the cloud car.

"This is what the cloud car looks like inside the window, you can take a look~" Ma Tian said.

Now the speed of the cloud car has almost reached Mach 5, in fact, now looking out from the window, basically only a vague afterimage can be seen, because the speed is too fast.

Moreover, the cyclone of the reverse flow is still "fighting" outside the window, interfering with the vision, and Ma Tian knows that once the speed exceeds Mach 5, it will enter the thermal barrier, then the scene outside the window will completely turn red, because the thermal barrier layer heats the magnetic alloy skin outside.

The audience in the live broadcast room was stunned, and the teleportation scene caused their eyes to be dazzled, a bit like the feeling of turning the mouse to 100 zero density and then scurrying around.

[Ah, God Ma Tian quickly close this window, it's too flashy! ] 】

[My eyes are going to see flowers~]

……

It turns out that it is not that the faster the speed, the more exciting the scenery outside the window, at least now the audience in the live broadcast room has been tortured.

Ma Tian also made a small window and put it on the top left of the live broadcast room, watch what you want, and continue to watch satellite images if you don't want to watch.

The speed of the "Jingxiang No. 1" is still accelerating, reaching 6,000 km/h, and the carriage to reach Hengshui Station has also begun to break away from the back.

Because the speed is already very fast, the braking distance at this time has to come to more than 40 kilometers to slow down the carriage to 0 pit stop.

"Yokosui Station has arrived!"

……

"The capital has arrived!"

With the time fixed at 18 minutes and 08 seconds, the Jingcheng Station, which is 1383.7 kilometers away from Xiangshi, has arrived, and the average speed of the cloud car has reached 4150 km/h, while the maximum speed has reached an astonishing 10782 km/h.

When the staff at the Beijing Station watched the intact "Jingxiang No. 1" slowly drive into the station, and took dozens of cups from the car, as well as Shang Wen's pleasant face, the whole station was completely plunged into a sea of joy.

The Chinese people watching in the live broadcast room also cheered, which means that the live broadcast room does not have the function of rewarding gifts, otherwise, the entire live broadcast room will become a sea of gifts.

Chinese people will use gifts to express their congratulations and express their excitement.

The world's first vehicle of more than 10,000 km/h was born!
