Universe dominance

Li Fu nodded with satisfaction when he saw the results of the experiment. The power of "point light" is almost comparable to that of primary energy weapons. This light speed weapon is very advantageous when fighting in the void of the universe.

If a war breaks out in the void of the universe, the spaceships, space battleships, etc. on both sides will be very fast, basically at a speed of tens of kilometers per second. At such a fast speed, traditional weapons cannot be used at all. In any case, even the fastest intercontinental missile on earth cannot catch up.

What's more, in the vacuum environment of the universe, many weapons cannot be used at all. Aircraft, guns, etc. used in wars on earth are basically useless.

Only weapons such as space-based weapons and energy weapons can be used in the universe. First of all, the attack speed of the weapon is fast enough. The speed of light attack can truly be as fast as lightning. No matter how fast your spaceship or space battleship flies, It is absolutely incomparable to the speed of light.

Secondly, the power of energy weapons is theoretically unlimited, and the attack method of energy weapons can continue to attack as long as there is energy. It is a weapon born for cosmic war.

"It's powerful enough. I wonder how far its attack range is? Is there anything that can affect its attack?"

After listening to Bai Cai's words, Chen Bin asked thoughtfully.

"Because light is diffusive, the farther it travels, the more powerful it spreads. Even if the light and energy of a laser weapon are highly concentrated, it will still spread. According to our theoretical test data, the point light is most effective at the farthest The attack range can probably reach 100,000 kilometers. Of course, if we improve the energy compression technology in the future and further compress more energy and light to a single point, its range can also be continuously improved. "

"As for the things that limit its attack, such as heavy rain, heavy fog, heavy snow and other weather conditions, laser weapons can basically be declared useless, because light simply cannot penetrate areas containing a large amount of smoke and water vapor."

"In addition, the instruments of laser weapons are very precise instruments and cannot be damaged in any way. Once there is any damage, it will be scrapped directly."

Bai Cai nodded and explained the shortcomings of the laser weapon.

"With a range of 100,000 kilometers, this attack distance is enough, but it will be affected by so many effects. It seems that if this laser weapon is deployed in space, it is impossible to completely control the ground. The enemy can completely control the ground on cloudy and rainy days. Attack it, or artificially create smoke to affect it."

Yu Liang nodded. Many things are not scary as long as you know their flaws. The power of laser weapons is very powerful, but it is affected by the weather.

"This laser weapon itself is more used in space warfare. In the vacuum environment of the universe, the power of the laser weapon can be fully unleashed. When dealing with ground targets, there are still many things that affect it."

Li Fu also nodded slowly. On a rainy day, the laser weapon would be worse than a fire stick and would have no effect at all. But in the space environment, it is a real sharp sword.

"With the weapon system now in place, our Sky City project can continue. We need to speed up the pace."

…

At the Fuyun Group Space Center in Longling Town, on the huge airport, a huge "Hercules" aerospace plane rose into the sky with bursts of roars, trailing a blazing white tail flame, and soon disappeared in the sky. In everyone's sight, in just a few minutes, it had broken through the earth's atmosphere and entered outer space and began to orbit the earth.

In the aerospace plane, Luo Xiaoyao, Zhan Fei and other astronauts trained by Fuyun Group have all put on spacesuits that can form in space, and are ready to start the intense and dangerous work of building a space in the sky. city!

Here at the ground command center, Li Fu, Chen Bin, Yu Liang and others were all nervous at this time. After all, this was the first time to build a large-scale man-made object in outer space. Although many experiments had been carried out, and With the assistance of a huge aerospace aircraft, there is no technical difficulty at all.

But after all, they were building large man-made objects in space, and this time they were laying the foundation for the Sky City, so everyone became nervous at this time.

"Didi! The Clairvoyance navigation system is tracking and positioning, and the aerospace plane is expected to enter the scheduled orbit in 10 minutes."

Fuyun Group's own Global Positioning System Clairvoyance system is fully operational in space at this time, and dozens of satellites provide extremely accurate positioning services for aerospace aircraft.

"Altitude 510 kilometers, speed 10.2 kilometers per second, reaching the predetermined orbit, requesting instructions!"

The virtual machine worn by Luo Xiaoyao reported all the current status of the aerospace plane. After several orbit changes, the aerospace plane has reached the predetermined orbit.

Generally, large man-made objects in space, such as the International Space Station and Tiangong, are not too high because they need to use the earth's gravity to orbit, so that they can orbit the earth with almost no energy consumption.

For example, the height of the International Space Station is only between 390 kilometers and 405 kilometers, and the original orbital height of Tiangong is only between 330 and 350 kilometers. Later, after the emergence of space planes, China changed the orbit of Tiangong and raised its altitude. As high as 430-450 kilometers, the main reason is that the mass of Tiangong is constantly increasing.

If the orbit is too close to the earth, the influence of the earth's gravity will continue to decrease every year, and eventually it will be completely absorbed to the ground by the earth's gravity, causing a devastating disaster. Therefore, the greater the mass, the higher the orbit will be.

Of course, the higher the orbit, the weaker the binding force of the earth's gravity, and the greater the risk of escaping the earth's gravity and drifting into space, so the requirements for a powerful propulsion system are higher.

China, which has mastered powerful plasma engines, naturally does not need to be afraid of this. There are multiple powerful plasma engines installed on Tiangong, which are enough to ensure the safety of Tiangong. The same is true for Li Fu.

The plan of the Sky City is very large, and the mass is also very large. The orbital height is naturally higher. As for power propulsion, there is no need to worry about it. Plasma engines are also indispensable.

"start!"

After receiving the news, Chen Bin, who was responsible for the construction of Sky City at the ground command center, did not hesitate. At this time, the orbit and speed of the aerospace plane had fully met the requirements.

In space, the side of the huge "Hercules" aerospace plane slowly opened, revealing its huge belly. The first thing stretched out were several flexible mechanical arms, and then Luo Xiaoyao, Zhan Fei and other astronauts also Wearing spacewalking spacesuits floated out of the aerospace aircraft, and there was a long rope connected to the back of each person's spacesuit.

Originally, with the technological strength of Fuyun Group, it was completely possible to develop a spacewalking spacesuit that did not require rope connection. However, for the sake of safety, this ancient method was adopted, and the astronauts felt more at ease.

Inside the huge belly of the aerospace plane, driven by the machine, large parts began to be brought out one by one by mechanical power. Because space is only subject to microgravity, it does not require a lot of force to push an object with a huge mass into motion. stand up.

The robotic arms flexibly carried out these strictly calculated parts in the order that had been set long ago, and Luo Xiaoyao and others began to get busy.

Fuyun Group did not adopt the construction methods of the International Space Station and Tiangong. The construction methods of the National Space Station and Tiangong are actually very simple. First, a main module is launched into space, and then each space capsule is launched and docked. The main cabin was slowly expanded by analogy, and finally slowly formed its current huge scale.

The advantage of this operation is that it is very simple to build. The space capsule can be launched into space with a rocket, and it is easier to dock. One capsule after another is slowly docked.

The disadvantage is that astronauts can only live in one capsule, and the space is very limited. They cannot conduct large-scale scientific experiments, and future development is also affected, because only one space capsule and one space capsule can be added continuously. No matter how many space capsules there are, the space itself is quite limited. There is no way to build large factories, laboratories, etc. in space.

The construction of the Sky City is completely different. The technical difficulty is very high at the beginning. It is necessary to build the main skeleton of the Space City's space port first. Then slowly build the space port first, and then slowly build the space port. Based on the port, living areas, factory areas, agricultural areas, scientific research areas, etc. are constantly built.

Its advantage is that the development and expansion of Sky City will not be limited in the future. It can have a very large space, enough to build large space factories, space agricultural areas, living areas, etc. At the same time, because it has advanced space ports, Sky City Parking the aircraft is more convenient and faster.

Of course, its disadvantages are that it is difficult to build and requires high technology. The construction of the skeleton is very troublesome from the beginning, and it cannot be simply docked one space capsule after another like the International Space Station.

But this is not a problem for Li Fu. It is not a problem for the scientists of the Fuyun Group. They have the world's largest "Hercules" aerospace plane. In addition, Li Fu has the guidance of the seeds of civilization. Building a space city is definitely not a problem. What a problem.

The huge aerospace plane can transport thousands of tons of materials at one time, and the quality of the materials transported in one takeoff has exceeded the quality of the International Space Station. If we still use traditional technology to build the city in the sky, it will not be difficult at all.
