2020 is a special year.

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

During the Spring Festival this year, Mu Yang and his family celebrated the New Year in Mu Mansion and could not go anywhere.

Mu Yang was reborn from 2022 to the past. He doesn’t know what the future will be like. He has no ability to change this incident. He also asked people to investigate, but the source could not be found. He had to do a good job in the company in accordance with the requirements of the relevant departments.

Work.

Since my family took Life No. 1, their bodies have become healthier and they look younger.

My grandparents have changed the most. They feel twenty years younger. Their originally gray hair has turned into black hair.

Their parents are also more than ten years younger, but Mu Yang and Song Xuelu still look like they are in their twenties.

Relatives and friends also noticed the changes in Muyang's family, but they only thought that this was the result of better living conditions and good maintenance, and did not think about high-tech drugs.

Mu Yang successfully developed Life No. 1 in March 2017. Now, nearly three years have passed since he started developing Life No. 2.

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

A month ago, his achievement points were reported again, and the total achievement points had reached 9,500 points.

Now that I have spent 500 achievement points, I still have 9,000 achievement points left.

In the past year, except for spending 240 achievement points on developing graphene, Mu Yang did not develop any new technologies.

He has many scientific research projects on hand and has to supervise students, so he spends a lot of time.

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

There is no rush in the development of Life 2, just take your time.

He is now more worried about the future environmental situation.

If the family continues to take Life No. 2, their physical condition will be better.

After the New Year, Mu Yang continued to invest in scientific research on vacuum tube maglev trains, and went to the laboratory to have a look when he had time.

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

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

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

A few days later,

The cherry blossoms on both sides of the road at the Xinghai Group headquarters base are already in full bloom. April has arrived. The entire city has a mild climate, moderate rain, and pleasant scenery.

The area from the headquarters base to the Xinghai Group Yangfu District Industrial Park is more than ten kilometers long and two to three kilometers wide, and 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. Semi-circular pipes are laid on the piers. This is the vacuum pipeline test route of Xinghai Group.

It is impossible to see the internal situation from the outside. During this period, Xinghai Group staff frequently inspected this route.

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

There have been driving tests 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. It does not take long to slow down after reaching the maximum speed, so it is impossible to fully test its performance.

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

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 is always accelerating steadily. Unlike a car, which may accelerate in three seconds to reach a speed of 100 kilometers per hour, the same power can accelerate six times.

If the speed cannot reach 200 per hour in seconds, the main reason is that the air resistance has increased.

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

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

Time passed quickly, and finally it was time for the high-speed opening test of the vacuum tube maglev train.

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

In the morning, there was drizzle in the sky 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 will have no impact on it.

The time soon arrived at 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, let's test according to the test process." Mu Yang replied seriously, also looking forward to it.

Some time ago, he had seen the test plan. Today's test is without load, that is, an empty test.

The testing 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 section.

During the test process, 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 are no problems in the test, more carriages will be added later.

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

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

There is no driver in the car, everything is controlled remotely.

"Start the test! Check the orbital vacuum condition!" Zhang Nan, as the command leader, personally ordered the test 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 is completed, docking begins, and the train enters the test track. After about a few seconds, the vacuum pipe hatch is closed again.

The vacuum tube maglev train entering the vacuum environment is much more troublesome than powering it, and it takes two to three minutes longer.

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

The environment for passengers' excretion, water use, etc. on the car is all closed. It is forbidden for excrement or even air to be discharged into the vacuum pipe.

If the train breaks, it will definitely have a serious impact on passenger safety. 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 one after another, the train with three carriages quickly started to speed up.

"Acceleration 10m/s2, speed in the first second 10m/s, traveling 5 meters..."

On the big screen, the time is displayed: "0:00:01,10m/s2,10m/s,5m..."

When the time came to the tenth second, the speed had increased to 8m/s, which was equivalent to 359 kilometers per hour, and the distance from the starting point was already 6 meters.

【0:00:10,10m/s2,8m/s,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. Senior officials such as Mu Yang and Zhou Chen had been staring at the data and the video of the train traveling on the track.

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

The train is also equipped with environment sensing cameras, millimeter wave radar, ultrasonic radar and other instruments, which can observe the situation around the train.

Judging from the current performance, it is relatively stable.

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

With an acceleration of 10m/s2, it can increase to a speed of 30m/s in three seconds, which is equivalent to 108 kilometers per hour.

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

【0:00:20,10m/s2,6m/s,5m...】

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

This is also the first time testing has reached this speed.

On the train, this speed was also displayed, and the train seemed to have no vibration.

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

【0:00:30,10m/s2,5m/s,6m...】

The speed reaches 1078 kilometers per hour!

Keep accelerating!

【0:00:40,10m/s2,0m/s,6m……】

4 kilometers per hour!

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

The deceleration acceleration reached -15m/s2, decelerating to zero in 26 seconds, and the sliding distance was about 5070 meters.

This deceleration acceleration is barely adaptable to humans, and the braking deceleration of a high-performance sports car is comparable to this.

However, the vacuum tube maglev train brakes do not use friction to brake, but the braking force in the opposite direction.

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