Chapter 608: The Test That Shocked the World

2020 is a special year.

Muyang requires the family homes and companies to be disinfected every day, and strictly controls the entry of external personnel into the Xinghai Group headquarters base.

During the Spring Festival this year, Mu Yang and his family spent the New Year in Mu Mansion, and they couldn't go anywhere.

Mu Yang was reborn from 2022 to the past, he doesn't know what the future will hold. He has no ability to change this incident, and he also asked people to investigate, but they couldn't find the source, so they had to do the company's work well according to the requirements of the relevant departments.

Since my family members took Life No. 1, they have become healthier and younger.

Grandparents have changed the most. They feel twenty years younger, and their gray hair has turned into black hair.

Parents are also ten years younger, while Mu Yang and Song Xuelu still look like they are in their twenties.

Relatives and friends have also noticed the changes in Mu Yang's family, they just think that it will happen after the living conditions get better and the maintenance is good, and they don't think about high-tech drugs.

Mu Yang successfully developed Life No. 1 in March 2017. It has been nearly three years since he started to develop Life No. 2.

This is a prescription that theoretically increases life expectancy by 30 years, and requires 500 achievement points.

A month ago, his achievement points were reported again, and the total achievement points had reached 9500 points.

Now that 500 achievement points have been spent, there are still 9000 achievement points left.

In the past year, apart from spending 240 achievement points to develop graphene, Mu Yang did not develop any new technology.

He has a lot of scientific research projects on hand, and he has to guide students, which takes a lot of time.

Mu Yang's most important goal at present is to quickly upgrade the reading system to level 8.

The development of Life No. 2 is not in a hurry, so take your time.

He is now more worried about the future environment.

If family members take Life No. 2 again, their physical fitness will be even better.

After the new year, Mu Yang continued to invest in the research of the vacuum tube maglev train, and went to the laboratory to have a look when he was free.

With his participation, the testing and debugging progress was much faster than planned.

During this period, a series of tests on the vehicle's power, braking, suspension, power stability, air conditioning, lighting, fire, emergency braking, etc. were completed.

By March, the number of astronauts on the Halo space station had reached 30, and the astronauts with psychological problems had returned.

A few days later,

The cherry blossoms on both sides of the highway of Xinghai Group Headquarters Base are already in full bloom, and April has arrived. The climate of the whole city is mild, the rain is moderate, and the scenery is pleasant.

The area from the headquarters base to Xinghai Group's Yangfu District Industrial Park, which is more than ten kilometers long and two to three kilometers wide, has been included in the future development scope of Xinghai Group.

In the middle area, there is a straight viaduct with a height of more than ten meters and a length of more than ten kilometers. A semicircular pipeline is laid on the pier. This is the vacuum pipeline test route of Xinghai Group.

It is impossible to see the internal situation from the outside. During this time, the staff of the Xinghai Group frequently checked this route.

After several months of debugging, it was finally decided to start the high-speed traffic test on April 5th.

There was also a driving test before, but the maximum speed did not exceed 300 kilometers.

In fact, the test route of more than ten kilometers is still too short compared to the route that requires a speed of more than 2,000 kilometers per hour. After reaching the maximum speed, it will not take long to slow down, and it is impossible to fully measure its performance.

The Xinghai Group built this track of more than ten kilometers mainly to verify its reliability. If you want to test the highest speed stably, you need a track of hundreds of kilometers.

According to the theoretical starting speed of the vacuum tube maglev train, it can reach a speed of 100 kilometers per hour in two or three seconds, and it has been in a stable acceleration. It can't reach the speed of 200 per hour in seconds, mainly because the air resistance has become larger.

But in the vacuum pipeline, because the air is thin or even in a vacuum environment, there is no air resistance, so the air resistance on the train is constant, that is, zero. As long as the power is continuously provided, the train can continue to accelerate and increase the speed.

If the power supply is stopped, the train can maintain the same speed, which is the same as the flight of satellites in space.

Time passed quickly, and finally came the high-speed test of the vacuum tube maglev train.

Both Mu Yang and Zhou Chen came to the test starting point, and there were several company executives who came to visit.

In the morning, the sky was drizzling and the air was fresh.

For the vacuum tube maglev train, it travels in a closed space. As long as the track is not damaged, bad weather has no effect on it at all.

The time soon came to ten o'clock in the morning, and Zhang Nan reported to Mu Yang: "Chairman, everything is ready and can be tested at any time."

"Okay, test according to the test process." Mu Yang replied seriously, also looking forward to it.

Some time ago, he had seen the test plan, and today's test is without load, that is, empty vehicle test.

The test process needs to be carried out at different speeds, gradually increasing from low speed to high speed, and multiple tests are required for each speed segment.

During the test, testers need to collect and record various data of the train, including acceleration, maximum speed, braking distance, lateral acceleration, floating stability, power consumption, etc.

The train tested today has a total of three carriages. If there is no problem in the test, more carriages will be added in the future.

After the empty test is passed, the load will be loaded for testing.

Mu Yang went to the train site to observe, and then went to the control center.

There is no driver on board, everything is controlled remotely.

"Start the test! Check the orbital vacuum!" Zhang Nan personally ordered the test as the commander today.

"The temperature is 21 degrees Celsius, the humidity meets the requirements, and the vacuum pressure..." Each tester received the order and quickly reported the data.

"Check the train!"

...

"Close the hatch and start vacuuming!"

In about two minutes, the vacuuming process was completed, docking began, and the train entered the test track. After about a few seconds, the door of the vacuum pipe was closed again.

The vacuum tube maglev train enters the vacuum environment is much more troublesome than the power, and it takes two or three minutes longer.

The train is also closed, the air is ventilated inside, and the air pressure is normal. Hundreds of passengers in each car have to breathe. This air system is not simple.

The environment such as the excretion and water use of the passengers on the car is all closed, and it is forbidden to discharge excrement or even air into the vacuum pipe.

If the train breaks, it will definitely have a serious impact on the safety of passengers. The train must stop quickly, then close and block this section of track, and open the valve between the vacuum pipe and the outside world.

"Start the vehicle!"

Following Zhang Nan's orders to go down, a series of three-carriage trains quickly started to speed up.

"Acceleration 10m/s, speed 10m/s in the first second, travel 5 meters..."

On the big screen, display time: "0:00:01, 10m/s, 10m/s, 5m..."

When the time came to the tenth second, the speed had risen to 99.8m/s, equivalent to 359 kilometers per hour, and the distance from the starting point was already 498.6 meters.

[0:00:10, 10m/s, 99.8m/s, 498.6m...]

Judging from the data performance, the acceleration is very stable, with a little fluctuation, which is mainly affected by the straightness of the track and the slope.

All the scientific researchers on site were very nervous, Mu Yang, Zhou Chen and other high-level officials had been staring at the data and the video of the train running on the track.

Cameras are installed inside and outside the track to observe the train situation in real time.

The train is also equipped with environmental perception cameras, millimeter-wave radar, ultrasonic radar and other instruments, which can observe the surrounding conditions of the train.

Judging from the current performance, it is relatively stable.

A speed of more than 300 per hour is nothing at all, and the same acceleration is still maintained.

The acceleration is 10m/s, and the speed can be increased to 30m/s in three seconds, which is equivalent to 108 kilometers per hour.

It reaches a speed of 100 kilometers per hour within three seconds, which is still within the tolerance range of human beings, but the feeling of pushing the back will be very strong. If you have ridden a high-performance sports car or driven a high-performance new energy vehicle, you will feel the same.

[0:00:20, 10m/s, 199.6m/s, 1998.5m...]

In just a short while, 20 seconds passed, and it traveled about 2 kilometers, and the speed reached 718 kilometers per hour.

This is also the first test to reach this speed.

On the train, this speed was also displayed, and the train did not seem to vibrate.

When the acceleration reaches 30 seconds, the speed officially breaks 1,000!

[0:00:30, 10m/s, 299.5m/s, 4468.6m...]

The speed reaches 1078 kilometers per hour!

Keep accelerating!

[0:00:40, 10m/s, 399.0m/s, 7995.6m...]

The speed is 1436.4 kilometers per hour!

However, to reach this speed, you must slow down.

The deceleration acceleration reached -15m/s, decelerated to zero within 26 seconds, and the sliding distance was about 5070 meters.

This deceleration acceleration is barely adaptable to human beings, and the braking deceleration of a sports car with good performance is comparable to this.

It's just that the brake of the vacuum tube maglev train does not use friction to brake, but reverse braking force.

If you don't slow down, the train will hit its head.

In normal operation, the braking deceleration must not be done like that, and it can only be slowed down slowly, and the test does not matter.

After all, the test track is only a dozen kilometers long. But no matter what, the first test, the speed can reach 1436 kilometers is very good.

Judging from the test process, the operation is relatively stable, and the train vibrates slightly, which is within the design range.

Next, the train returned in the opposite direction, taking the same amount of time.

The train is suspended to check the operation.

Ten minutes later, Zhang Nan reported the test situation to Mu Yang, and the result was good.

"The acceleration can be increased to the maximum, and the acceleration time is 30 seconds!" Mu Yang thought for a while and gave the order.

The acceleration speed is one hundred per hour in two seconds, and the starting speed is very fast.

The maximum acceleration of the train is 15m/s. If the acceleration is 30 seconds, the theoretical speed can reach 1620 kilometers per hour, and the driving distance is about 6.7 kilometers.

The braking time also needs to be the same. If you accelerate for a few more seconds, you will not be able to stop the car at all, and the train will definitely hit its head.

"Okay, Chairman!"

Zhang Nan replied solemnly that the chairman knew more about the technology of vacuum tube maglev trains than he did, and I believe he was confident.

When the project started, no one believed it would succeed.

However, from the current point of view, it has been considered a success, indicating that this technology is feasible.

Zhang Nan and other researchers were very excited, indicating that they had successfully developed it.

Of course, the two runs were all empty tests, and no load was loaded yet.

In any case, the speed of the train reaches more than 1400 kilometers per hour. If it is disclosed to the outside world, it will definitely shock the world.
