Chapter 1631 The Great Wall of Steel 3

Lei Xingfeng asked, Li Shaolong and Murong Feixue also looked at Zhang Hao with questioning eyes.

Previously, the fastest and most powerful railguns of the Blue Star Group and the Dayang Group were the "sniper" railguns built on the back of the Terra Turtle, with a caliber of 3 cm and a projectile mass of about 2.8 tons. The export speed can reach 0.48 times the speed of light.

Such cannonballs are a bit reluctant for Jinxian. It's just because the Terracotta Turtle can accelerate in advance to increase the exit speed of the rail gun, which is not bad in practical applications. But it can only be said that it can.

For Da Luo Jinxian, as long as he is prepared, the power of the rail gun can basically be ignored. But if you are not prepared to say otherwise.

But no matter what, facing the Da Luo Jinxian level, the power of the rail gun is already a bit tasteless. It's just that limited by technology in the past, it is difficult to continue to improve the power of rail guns in a short time. This is also an indisputable fact.

Facing Lei Xingfeng's inquiry, Zhang Hao explained: "Master, the guide rail we are currently building can reach a length of 60,000 kilometers. According to theoretical calculations, the maximum ejection speed of the rail gun will reach 0.95 times the speed of light.

In addition, the projectiles of the shells, etc. have also been changed this time.

In the past, projectiles were not completely degenerate materials, but hollowed-out structures, and the rest were filled with ordinary materials. But this time we made completely degenerate material shells.

The density of degenerate materials can reach at least 60 tons per cubic centimeter. A 3 cm shell has a volume of more than 14 cubic centimeters and its mass is as high as 850 tons.

In addition, due to the mass expansion at high speed, at 0.95 times the speed of light, the real mass of the shell expands by about 3.2 times, which is 2720 tons.

Master, how much destructive power will a 2,720-ton shell hit a target with a cross-sectional area of ​​3 cm in diameter at 0.95 times the speed of light in an instant? "

Lei Xingfeng blinked: Although he is a 'master', he still can't understand such scientific issues.

Zhang Hao said directly: "Assuming that when the demon saint is attacked, the armor and defense thickness of the demon saint is 10,000 kilometers, then the collision time, that is, the time for the rail gun to release energy, is about 0.035 seconds.

According to the momentum formula, it is 2720 tons multiplied by 0.95 times the speed of light, and then divided by 0.035 seconds. That's an astronomical figure. Its real attack power is not weaker than ordinary quasi-holy supernatural powers at all.

Master, the laws of physics seem simple, but the laws of physics developed to the extreme are not a kind of supernatural power. "

As he said that, Zhang Hao looked at the 'Baxia' who was being transformed in front of him, and his eyes were somewhat longing and fascinated, "The railguns currently being transformed have three calibers.

The first type has a caliber of 3 cm, a projectile mass of 850 tons, and a design exit speed of 0.95 times the speed of light; one acceleration requires the consumption of about 940,000 tons of nuclear fuel mixed with hydrogen and helium.

The second type of caliber is 30 centimeters, and the mass of shells ranges from thousands of tons to hundreds of thousands of tons. The design export speed can reach 0.88 times the speed of light at the fastest. This model is mainly used for tough battles, attacking planets, fortresses, etc. There are also many types of shells, which can be replaced according to actual needs.

The third type of caliber is 5 meters, the maximum mass of the shell can reach 10 million tons, and the fastest design speed can reach 0.56 times the speed of light. This is the craziest railgun technology currently designed, aimed at some super-giant defense methods against large starry sky behemoths and the sky demon world.

Moreover, with a diameter of five meters, the types of shells can be designed more fully. We are currently working on a missile that relies on railgun acceleration, etc. There may be unexpected surprises. "

In the past, because the technology was not enough, and the speed of the rail gun was too fast, it would lead to unstable space, and there was no way to add storage space inside the shell. The final railgun has limited shell types. It is nothing more than a change in weight, or adding a broken shotgun function.

But now there is a 100,000-kilometer Baxia, and a 60,000-kilometer-long rail gun can be built on its back, and some crazy ideas can be realized.

When the rail gun accelerates, it will burst out a powerful recoil beyond imagination. In addition, the rail gun consumes a lot of energy and currently only has the nuclear island technology of cold nuclear fusion, which requires the construction of a large number of nuclear islands for energy supply. Therefore, the current technology can only be a "trick" - building the rail gun on the carapace behind the Terracotta Turtle.

Even the body of the land god fish can hardly bear the recoil of that kind of crazy level rail gun. Regardless of the speed of the rail gun built on the terrestrial fish, it can reach 0.48 times the speed of light, but the quality of the shell is only half of that of the terrestrial turtle, or even lower.

The speed and technology of such a rail gun are naturally affected by the size of the Terracotta Turtle for the time being. It wasn't until this time that I found the demon saint's mount, a 100,000-kilometer bully.

Needless to say, after Lei Xingfeng sealed the giant beast, Zhang Hao was about to come over and start to transform it.

Sure enough, with plenty of room to play, the engineering designers of Dayang Group actually designed such a crazy rail gun under the current limited technical conditions.

As long as the foundation is solid, the railgun can be stacked infinitely. In fact, it is an alternative and open particle collider, but the 'particle' is a bit big. And the target that this 'particle' is going to hit is a bit different.

Rail guns require extremely high technology and precision, and the current technology is not enough to forge too long rails. Only thousands of kilometers can be processed at a time.

The rail part of the railgun is very finely and complexly processed. It must be suspended in the void for forging, stretching, and then laser polished to form a sheet. Then the sheets are stacked together, and then after laser grinding, forging, coating, and testing, it is considered successful. During the forging process, superconducting cables and the like are also pre-embedded.

Each guide rail is actually made of tens of thousands of sheets superimposed. The material requires magnetic conductivity and beam magnetism; it also needs to have sufficient strength and impact resistance, etc. Only folded and forged composite materials can meet the stringent requirements.

Finally, all guide rails will be fixed to professional bases and brackets, and a viaduct bridge will be built on the slightly curved back of Baxia as a whole.

The rails of rail guns are not straight. Rather, it has a certain arc.

In fact, straight guide rails are naturally the best; but construction is difficult.

The back of Baxia is curved; if you want to build a straight rail gun, you need to build a viaduct. The tallest viaduct is probably more than five or six thousand kilometers long. Considering the rail gun's strong recoil, etc., this is not realistic.

So the design is to use the principle of electromagnetic cutting force to design an arc-shaped guide rail. Therefore, the rail gun as a whole fits roughly with the back of the Ba Xia. Only in order to maintain the level of the exit, a viaduct was erected, with a height of about 300 kilometers.

In addition, in order to provide energy for the rail gun, densely packed nuclear islands were built on Baxia's back and abdomen.

Because Baxia is strong enough, an atmosphere is formed around him, forming an ecological circle. So for the sake of Baxia, there are actually millions of people settled down. These are military personnel who will be responsible for the operation and maintenance of the railgun.

Zhang Hao explained it very clearly, Lei Xingfeng finally looked at the 'Baxia' in amazement.

Like all monsters in the Heavenly Demon World, Ba Xia also lost his sense of sovereignty and was controlled. At present, it is Daluo Jinxian Zhang Yinghao, Jiang Hang and others who control Ba's subconscious mind. Everyone controls it together to prevent any accidents when one person controls it.

Dayang Group is responsible for maintaining the computer and other technologies that control the railgun.

When he left Baxia, Lei Xingfeng was still shocked and said: "Building such six railguns will consume the resources of two large gaseous planets. A full-power salvo of six railguns will consume seven million tons of nuclear fuel.

It's really... crazy.

It turns out that the seemingly ordinary physical technology can be so tyrannical when it is brought to the extreme. "

Zhang Hao smiled and said nothing, and finally everyone came to 'Xue Yao Xing'. This galaxy named after Zhou Xueyao is now the absolute life research center of the Blue Star Group.

From a long distance, you can see millions of "green planets" around the stars, and those are all space plants. Now these space plants have grown to thousands of kilometers in diameter, and each one is a small world.

These space plants are about 60 million kilometers away from the star at the nearest point, and the direct sunlight temperature can reach hundreds; the farthest is 250 million kilometers, and the direct sunlight temperature is only about zero degrees, but relying on the greenhouse effect and other adjustments, it is still good .

Spaceships continue to fly by, bringing basic mineral resources to these 'planets', and picking medicinal materials from these planets.

"The daily production of a single type of medicinal material by such a 'planet'-shaped space plant is almost equivalent to the annual production of the same type of medicinal material by small and medium-sized interstellar countries in the past.

The small and medium-sized interstellar countries mentioned here are countries like the Golden Eagle Empire with a range of about forty to fifty light years.

If it is a rare or precious medicinal material, it is almost equivalent to its output of ten or more years. And the medicinal materials here are of good quality.

Only because of technical and time reasons, at present, medicinal materials with medicinal properties of a thousand years can be produced at most. For many years, we have to wait.

Fortunately, the medicinal materials with a thousand-year medicinal effect are enough to meet the needs of Dharma-phase realm and below. "

Lei Xingfeng's figure flickered, looking around these 'planets'. It took Zhunsheng only an hour to circle the star.

Returning to the spaceship, Lei Xingfeng exclaimed again: "Amazing! No wonder the Blue Star Group can shoulder the burden of fighting against the world of sky demons, no wonder you have the confidence to build a second Ziweiyuan. Sure enough, man can conquer the sky!"

Zhang Hao's face showed a bit of arrogance just right: "Master, the next thing to visit is the real secret of the Blue Star Group. The sci-fi version of "Zhou Tiangong"! And the secrets of genes, energy, laws, and dimensions that are being studied !"

Lei Xingfeng suddenly tilted his head slightly to look at Zhang Hao, Zhang Hao who had been looking at him was a little embarrassed, and Lei Xingfeng smiled, "It's not a good thing for the little guy to be too brainy.

Letting me participate in the research of "Zhou Tian Gong" is your ultimate goal this time, right? "

As a smart person, what should Zhang Hao say? It is impossible to deny it, and it must be admitted generously, even if Zhang Hao himself does not mean it completely.

So Zhang Hao sneered: "I made Master laugh. I really can't hide this thought from Master."

Murong Feixue at the side withdrew her shocked gaze, and immediately followed Zhang Hao's words: "Of course. Master has seen more planets than you can eat rice.

However, I am also quite curious about the magically modified version of the exercises you mentioned on the Internet. "
