My technology affects the whole world

With the help of three giant Max machines, the construction of Xingshan was finally completed within a month. With the connection of the reserved cloud rails in the north and south sections of Xingshan, it took nearly 10 months, and the "Beijing-Hunan" cloud rail was officially announced!

Now, there is only one final step - the test of opening to traffic.

Ma Tian also returned to the City of Progress and began planning the final test for opening to traffic.

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

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

Each bullet section can be continuously inserted into the bottom of the previous bullet. In this case, if the last bullet breaks away, the overall shape will not change, but the length will be shortened a little.

The exterior structure is determined, and all that remains is how to design the interior to facilitate loading of goods, or in other words, people.

Although this experiment was about loading cargo, considering the more difficult manned experiments in the future, Ma Tian still felt that it would be better to consider manning them now.

Therefore, Ma Tian worked with engineers to install seats inside, and then considered what people in the car would pack, such as suitcases, schoolbags, etc.

Nowadays, suitcases must not be placed randomly like on high-speed trains. They must be placed in special cabinets to prevent them from running around.

Even each seat must be equipped with fixed straps to prevent people from running around. The acceleration of the cloud car is so fast. Passengers cannot be allowed to move around casually like taking a high-speed train. They must always stay in their seats, just in case.

It's not that you can't do anything. After you get used to the acceleration, you can still drink milk tea and water. The voice broadcast on the car will give you accurate to the second instructions when acceleration and deceleration will end, and when you can drink.

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

And the one I bought was still hot. According to the plan, the milk tea should still be warm when we get to them.

I believe that there may be an afterthought in the future - maybe warm milk and ride on a cloud car.

Once the design drawings of "Jingxiang No. 1" are finalized, they only need to be handed over to the corresponding engineers for construction.

Two weeks later, "Jingxiang No. 1" was officially manufactured and delivered from the workshop, and it stopped firmly at the starting station, the City of Progress.

After Ma Tian went inside and checked for the last time, he began to check the lines for the last time, checking the early warning cameras and detection instrument data installed on each road, and then used satellites in space to scan along the orbit to see if there were any suspicious people or objects. touch.

Perhaps many people are worried, what if someone deliberately sabotages the cloud car and damages the cloud track after it is started? After all, the cloud car was too fast and it was too late to brake.

In fact, engineers from the National Construction Commission have raised this issue very early on.

However, they shut up after looking at the material parameters of the magneto-solid alloy. The reason is that the strength of the magneto-solid alloy can actually withstand two armor-piercing tank rounds.

If someone wants to use ordinary explosives to blow up the cloud rail, it may take more than two hours to blow off the long alloy shell of the cloud rail. In the end, they will have to face a cloud rail that can withstand two armor-piercing tank shells.

Two hours was enough for him to send Bai Di over to kill 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 "Jingxiang No. 1" will start departing in 15 minutes and to pay attention to the carriages arriving at the station.

After thinking about it, Ma Tian posted another live broadcast of the cloud car on Weibo:

[The Beijing-Hunan Cloud Rail will be put into trial operation today. Interested friends can come and watch it on the Tianyu Xinghai official website in 15 minutes~~]

It's not that he has to pretend to be a wall, but mainly because Ma Tian wants to prove that he is not lying and that the speed of the cloud car can really reach more than 10,000 kilometers per hour.

Ma Tiandu posted a small comment in person, so the popularity was undeniable. Within a short time, the number of comments and retweets exceeded 1 million.

However, Ma Tian just didn't pay attention. He even felt it was noisy and didn't even turn on the meager notification.

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

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

At the same time, a special satellite was also transferred to follow and take pictures. Now only satellites can capture the speed of the cloud car, even if Bai Di went to follow and take pictures.

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

【I am the first! 】

【Grab the sofa! 】

[Is this a satellite view? 】

The number of barrages in the live broadcast room suddenly increased, and some people also discovered that this was a satellite perspective.

The satellite view is taken from a very high altitude, so the floors and roads are basically squares and lines, which are easy to recognize.

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

"Hello everyone in the live broadcast room, the train you are seeing now is the 'Beijing-Hunan No. 1'!" Due to the rush, Ma Tian did not arrange a commentator and simply spoke in the live broadcast room himself.

【Who is speaking? 】

[Is God Ma Tian talking? 】

[It’s not Master Ma Tian, ​​it’s my husband~]

…

Ma Tian glanced at the flying barrage and raised his eyebrows. These people were really capable, but their movements did not stop.

First, the satellite was operated to zoom in to see the four characters "Beijing-Hunan 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 an algorithm.

378km/h, 386km/h, 394km/h……

The speed of the train was slowly accelerating at 8m/s^2, and soon exceeded the speed of the high-speed rail.

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

864km/h…1200km/h…

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

Seeing the cloud car breaking the speed of sound in less than a minute, netizens with some common sense began to post comments.

[No, that breaks the speed of sound? Why is it so simple? 】

[Isn’t there a sonic boom cloud? Why didn't I see the sonic boom cloud? 】Some netizens also raised their own questions.

Seeing that many people were wondering about the sonic boom cloud in the barrage, Ma Tian also explained again: "

In fact, sonic boom clouds do not necessarily occur when the speed of sound exceeds the speed of sound. It also depends on the air humidity, etc. Strictly speaking, it is caused by a shock wave that exceeds the speed of sound.

In order to reduce the energy impact of this shock wave, I loaded the cloud car with a 'mirror breaker', which you can understand as a needle specially designed to break the sound barrier. Because of the existence of this needle, there will be no sound barrier, and naturally there will be no sonic boom cloud. "

【Ma Tian Da Shen Niu Bi~】

[Although I don’t understand it, it doesn’t stop me from knowing that Master Ma Tian is awesome. 】

…

Listening to Ma Tian's explanation, the group of people on the barrage began to change direction again and began to flatter Ma Tian.

Ma Tian looked at the rainbow fart on the barrage and smiled at the corners of his mouth. It felt right to invent a piece of technology and be recognized and praised by most people.

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

"Jingxiang No. 1" can break the speed of 10,000 kilometers per hour, which is definitely not just as simple as the words say.

Take this "mirror breaker" as an example. Without this thing, when the cloud car passes by at supersonic speed, people in a radius of at least 60 kilometers will be impacted by the "shock wave" generated by the sonic boom.

For example, almost all household glass in houses within 3 kilometers of the cloud rail will be broken. Some people's ears are even more fragile, and their eardrums will be burst and their mouths and noses will bleed.

Within 1 kilometer of the cloud rail, if the cloud car happens to pass by at a maximum speed of 10,000 kilometers per hour, the sonic boom can directly cause people to bleed from the orifices and die suddenly!

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

This "reverse flow hole" structure is hidden in the surrounding body of the cloud car. Its function is to reverse the airflow around the cloud car.

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

The simplest experiment is to place two pieces of A4 paper parallel to each other, and then if you blow air into the middle, you will find that the two pieces of paper are attracted to the middle.

Think about it, if we take the high-speed train, when the high-speed train enters the station, there will be staff telling us not to get close to the yellow line. That is because they are worried that the high-speed train passing by at high speed will produce Bernoulli's principle and cause us to be attracted to it and be killed.

Even when the high-speed train enters the station at that speed, we have to worry about Bernoulli's principle. Let's think about the cloud car passing by at 10,000 kilometers per hour.

Without these "countercurrent hole" structures, let alone standing outside the yellow line, even standing 500 meters away would be swept up by the cloud car passing by at high speed.

In addition to the "mirror breaker" and "reverse flow hole" mentioned above, there are also various designs such as thermal barriers and soundproof shells.

Therefore, the technology used in the design of a cloud car may be beyond the imagination of most people in the live broadcast room. If Ma Tian talked about it in detail, it would take at least three hours.

The "Beijing-Hunan Cloud Rail" has a total length of 1,383.7 kilometers. The first station it passes is Zhumadian Station, 432 kilometers away from the City of Progress.

When the speed of "Jingxiang No. 1" reaches 1,650 kilometers per hour, the last carriage begins to detach on its own, and it will continue to slow down until it stops at Zhumadian Station.

However, the audience in the live broadcast room did not know this situation, and they were shocked when they saw that "Jingxiang No. 1" suddenly cut off a section.

Question marks began to fill the live broadcast barrage.

Ma Tian had no choice but to popularize the "derailment technology" and told the viewers in the live broadcast room not to worry. This is a normal process. Then he specially divided a small window and placed it in the upper right corner to track the perspective of the carriage going to Zhumadian.

[Damn it, Niubi, can you still play like this? 】

[Sure enough, learning is still useful. Like me who don’t like to study, I only think of parking there and speeding up. 】

…

The live broadcast room was once again shocked by the design of the cloud car. It turns out that it can save time in this way.

Now the cloud car carriage has been divided into two parts. The cloud car on the main track is still accelerating, while the cloud car on the slave track going to Zhumadian is constantly decelerating.

Now everyone can intuitively feel the braking distance of the cloud car's deceleration. Even if it is only decelerating at a speed of 1,650 kilometers, the braking distance is more than 13.1 kilometers, and the deceleration time is more than 1 minute.

One minute later, the detached carriage successfully arrived at Zhumadian, indicating the success of the first stage.

The members who were in Zhumadian successfully got the specially designed "Beijing-Hunan Cloud Rail" train souvenirs from the carriage, as well as Hunan City's Cha Yan Yuese milk tea.

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

"The experiment at Zhumadian Station has been completed~"

【congratulations! 】

[Tianyu Xinghai Niubi, National Niubi! 】

…

There was also a lot of congratulations and blessings in the live broadcast room, as well as praise for the cloud rail construction unit.

The cloud car on the main track was still accelerating. Just as it was interrupted, its speed had reached an astonishing 5046 kilometers per hour.

Now even from the satellite, you can see it moving at an astonishing speed.

Ma Tian also typed in the code and directed the scene from the camera inside the cloud car.

"This is what it looks like looking out of the window from inside the cloud car. You can take a look~" Ma Tian said.

Now the speed of the cloud car has almost reached Mach 5. In fact, when you look outside from the window, you can basically only see a blurry afterimage because the speed is too fast.

Moreover, the counterflow cyclones are still "fighting" outside the window, interfering with the line of sight, and Ma Tian knows that once the speed exceeds Mach 5, it enters the heat barrier, and the scenery outside the window will completely turn red. That is because of the heat The barrier layer heats the magneto-solid alloy skin on the outside.

The viewers in the live broadcast room were stunned. The teleportation scene made their eyes dazzled. It was a bit like turning the mouse to 100 zero density and then running around.

[Ah, Master Ma Tian, ​​please close this window, it’s too flashy! 】

【My eyes are almost blurry~】

…

Facts have proved that the faster the speed, the more exciting the scenery outside the window is. At least the audience in the live broadcast room has been tortured for a while.

Ma Tian also made a small window and placed it on the upper left side of the live broadcast room. You can see what you want to see. If you don't want to see it, just continue to watch the satellite images.

The speed of "Jingxiang No. 1" was still accelerating, reaching 6,000 kilometers per hour, and the carriages that were going to Hengshui Station also began to detach from the back.

Because the speed is already very fast, the braking distance at this time has to reach more than 40 kilometers to decelerate the car to 0 for the stop.

"Hengshui Station is here!"

…

"The capital station has arrived!"

As the time was fixed at 18 minutes and 8 seconds, the Beijing Station, which is 1,383.7 kilometers away from Hunan City, was reached. The average speed of the cloud car reached 4,150 kilometers per hour, and the maximum speed reached an astonishing 10,782 kilometers per hour.

When the staff at Beijing Station watched the intact "Jingxiang No. 1" slowly drive into the station, and took dozens of cups from the car with a warm look on their faces, the entire station was completely in a state of despair. a sea of ​​joy.

The Chinese people watching in the live broadcast room also cheered. This means that the live broadcast room does not have a gift function, 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 with a speed of over 10,000 km/h was born!
