The "Ring Orbit" is a large spacecraft runway installed outside the Noah. It was carefully selected by the engineers to sit slightly above the entire hull perimeter.

Because it can only be implemented after Noah is out of sub-light, it is also a large project left behind.

According to the plan, it has a total length of about 40 kilometers, a width and a height of about 1.3 kilometers, in a complete circular shape, and a large number of three-dimensional docking facilities on it. The total area is 19.47 square kilometers!

In order to build this real behemoth, nearly 90 million tons of steel and cement were used, and various large spacecraft will also be assembled in a circular orbit.

It's not just a runway, it's even a small factory!

It is precisely because of the shipment of so much material that Noah's speed is reduced so quickly......

It can effectively solve the problem that the entrance and exit of the Noah are too small. From now on, various large spacecraft over 30 meters will be docked on the three-dimensional docking facilities attached to this orbit.

Because space is a gravity-free environment, the annular orbit adopts electromagnetic adsorption technology and superconducting magnetic levitation technology throughout the process. Each spacecraft is designed and produced with corresponding supporting facilities.

And today, it is the time for the test flight of the military A001 spacecraft......

Yu Yifeng looked at the report from the military, and was slightly nervous in his heart.

"Lao Xu, this kind of test flight is very dangerous. In particular, the Noah is still in a state of high-speed motion...... The speed of 24km/s is not low. ”

Xu Yunjin shook his head: "Theoretically, all the techniques have matured, and the usual training is enough. When you are a soldier, there will always be some dangers, and if you retreat when you encounter danger, then what kind of soldier is you? ”

"We can't keep them too well protected, we still have to take the risks!"

Yu Yifeng opened his mouth, but in the end he didn't say anything to refute it. He looked at the report in his hand.

A man named Matt? Beechcraft's pilots will fly an A001 spacecraft to complete the "all-manual" test flight.

He is the best overall performance of all soldiers, both in terms of nervous reaction speed and training in peacetime, he is a first-class level.

Although Xu Yunjin said this, he was still very nervous in his heart. For a high-speed vehicle such as a spaceship, the pilot's technique, ability, and psychological quality are very important.

Even, its ultra-high speed is already somewhat beyond the ability of human nervous reactions.

Fast enough, right? It can reach speeds of up to three or four hundred kilometers per hour, but it's a slag compared to a spaceship!

The minimum speed of the A001 spacecraft is almost 1,000 kilometers per hour, or 300 meters per second, which is three or four times that of a racing car.

That's just the minimum speed!

The top speed can reach 300 km/s, which is as long as an hour of racing in a second!

In particular, the process of landing is especially difficult, much more difficult than refueling in the air. Don't look at the width of the circular orbit is 1.3 kilometers, but the ultra-high speed of the spacecraft is nothing at all, as long as you are slightly distracted for a second or two, the plane will be destroyed!

In the event of a collision, there is a 99.99% probability of death, and there is basically no such thing as parachuting. Even at the moment of your death, you haven't reacted yet!

In order to reduce the occurrence of such accidents, spacecraft are usually unmanned and automatically landed by computers.

Such automatic flights, in the first dozens or hundreds of unmanned tests, have achieved satisfactory results, and its procedures have been quite perfect.

But computers are not omnipotent, and no one can guarantee that the computer will not make mistakes, and no one knows if there will be a day of manual driving. Therefore, it is necessary to perform a completely manual driving control test, as if the unmanned system is completely broken and needs to be taken over by humans.

"The action begins!"

Pilot Matt? Beechcraft took a deep breath, slightly complicated, and walked onto the ship.

The A001 is designed to have more than 500 passengers, but he is currently the only one in the cab, and everything needs to be controlled by him.

Everything related to this has been simulated countless times over the course of many years, and the steps are familiar even in sleep...... He was a little nervous, but not flustered.

He was wearing a pair of power armor, which would not affect the dexterity of his fingers or the vision of his eyes. This is also the last resort to save life, there are various life-sustaining devices on it, if something really happens, it can increase the chance of survival a little, and it is only a little.

Of course, he definitely didn't want it to work.

Press the switch button, enter the voice code, and the spacecraft spews out a light blue ionic flame and begins to accelerate forward. The electromagnetic acceleration system unique to the annular runway was turned on instantaneously, which also produced a certain thrust on the spacecraft......

All this is carried out under the surveillance system of the entire Noah, and some drone equipment is also tracking and shooting in the starry sky at any time.

Today's technology is not the initial stage of the 21st century. At this moment, thanks to the monitoring system, the images of the entire spacecraft are magnified and displayed on various screens of the Noah. In order to invigorate people and boost morale, this test flight will be broadcast live to the masses.

This is also a high-speed spaceship developed by human beings in the true sense!

Not only official journalists, but also many non-governmental people also ran to the astronomical observatory to carefully watch the entire test flight process, and at the same time broadcast live on the civilian network.

"Guys, as you can see, our Noah is moving at about 25 km/s. The A001 spacecraft will take off and land on this large, high-speed moving platform. It's a lot of difficulty.

Okay, it's already flying, the particle engine is spewing out light blue flames, the speed is accelerating, the visual acceleration is about 3 g, according to the formula S=(1/2)at^2...... About 31 seconds...... Ah, it's out of its circular orbit and heading into space! ”

"This is an ace pilot in the military, currently ranked first in the overall score, and he is also a veteran pilot during the Earth period...... Yes, his name is Matt? Beach. Let's always remember the name! ”

The narrator is a senior middle-aged male journalist. He speaks very quickly, can spit out a large number of words in a short period of time, and is full of passion and can mobilize people's morale. Provided, of course, that the flight is truly successful.

"Okay! It has already made it into space, and with the help of an ion engine, it is still flying at an accelerated speed, currently at about 25.6 km/s. According to the plan, the speed will be switched back when the speed reaches about 50 km/s. After all, we just want to test the safety of manual piloting, not to push the limits of the ship......"

"Well, the whole process takes about one to two hours. There shouldn't be much risk on this smooth ride. Don't go away, Captain Zhao Yao from the Ministry of Security will reveal the secret: the specific performance ...... of the new spacecraft A001"

At this moment, in the captain's room, Yu Yifeng and the others were staring at the screen tightly. Many scientists are analyzing the data, and they can see if there were any mistakes during takeoff, whether there were potential risks, and so on.

If there are uncontrollable factors, the pilot must be alerted at the first time, and even ordered to abandon ship and run away. After all, the power armor on the body has a certain life-sustaining function and can persist until people's rescue......

"How?" Yu Yifeng asked for the first time.

"Everything works!" The leader of the group said with a slight ease.

Everything is in order, and it is the expected result!

Seeing Zhao Yao on the TV with a black face, reading the manuscript with a smile on his face, Yu Yifeng looked up in some surprise. He asked, "How could it be him?" How could Zhao Yao be interviewed by a TV station? ”

Xu Yunjin said without raising his head: "I let him go." The results of the written test were not even comparable to the soldiers under him, and they kept complaining to me...... It's better to go to the TV station as a commentator! ”
