In a void more than 60,000 kilometers away from the moon, the first space factory of Xinghe Technology Group is still very busy here, and anti-gravity spacecrafts coming and going constantly transport materials from here.

The second phase of the space factory is in full swing, carrying human ambitions for the stars and the sea. This space factory was also officially named the 'Dragon Nest' factory not long ago.

The dragon's nest, where the dragon was born.

Significant meaning here, a series of dragons flying in the sky and universe will be born, leading the descendants of Yan and Huang in the sea of ​​stars.

In the first phase of the factory that has been completed, in a huge and empty room, scientists and engineers are floating in special spacesuits, and they are busy with each other around a super-large engine.

This super-large engine, it is very large, with a length, width, and height of more than 100 meters. It is like a huge building with countless dense lines, thick wires like adult arms, copper wire winding, and neat planning. Qi, people can't help but be shocked at a glance.

"I don't know how stable it is. It is better to use integrally cast parts to be more reliable. This kind of combination of various small parts has such a huge volume and the parts inside are designed to hundreds of thousands. , Reliability and stability are worrying. "

Qin Yi carefully looked at this behemoth in front of him.

This is a second-generation anti-gravity engine that Qin Yi, Yang Hongyan, and Zhang Jian led over 200,000 scientists and engineers over half a year.

The second-generation anti-gravity engine, which uses the gravitational force of the star, is actually the same as the star gravitation sail in science fiction, which is the same as the principle of the anti-gravity engine.

"We have no way to transport the integrally cast part into space. Its size is too large. With our current technology, we have no way to miniaturize it before it has matured."

"And it is foreseeable that for a long time in the future, the second-generation anti-gravity engine we will build will only grow in size."

Next to Qin Yi, Yang Hongyan said helplessly.

He now understands why Qin Yi insisted on paying such a huge price to build such a huge space factory in space.

Without such a large space factory, it would be impossible to say that a second-generation anti-gravity engine would be manufactured, because its size is really too large.

And it involves some manufacturing technology, it must be completed in space, under the environment of microgravity and vacuum, many high-tech products can achieve the most perfect state.

看来 "It seems that the project of the space smelting plant must also be put on the agenda, but at present, even if the space smelting plant is built, we transport the ore into space to smelt, it seems that there are some gains and losses."

"It is better to be able to mine asteroids, and smelting them directly is the most cost-effective and profitable."

Qin Yi smiled and nodded.

In my mind, I remembered the smelting technology of some interstellar civilizations that I had seen in the science and technology tower. I used powerful spacecraft to haul back asteroids with masses of hundreds of millions of tons, and then used the star light to directly smelt the asteroids.

In space, super-large parts can be directly cast for manufacturing large spaceships, space warships, etc. The overall cast parts are more stable, reliable and safe.

"I think stability and reliability should still be possible. In order to manufacture this second-generation anti-gravity engine, we spent hundreds of billions of Chinese yuan, almost all of which are made of real gold and silver."

"This large component made up of small components should not have any problems. The quantum computer has been repeatedly simulated."

On the side, Zhang Jian touched his chin and said that he actually did n’t understand why Qin Yi has always emphasized the use of large-scale integrally cast parts. In fact, in his opinion, large-scale integrally cast parts are naturally very good, but It does not have to be so.

"If it is a general small spaceship, aircraft, etc., of course, there is no problem, because the power is limited, the power of the engine is limited, and the overall structure and stability of the spacecraft are not high."

但是 "However, this is our second-generation anti-gravity engine. It can use the huge gravitational attraction of the star once it is installed on a large spaceship."

"Once it starts, its huge power will all act on the spacecraft, and it will also act on itself. For the spacecraft using the second-generation anti-gravity engine, according to our current calculations, its speed will be The anti-gravity spacecraft is now hundreds, thousands of times even able to reach a certain proportion of the speed of light. "

"You can imagine that under such a powerful force and at such a terrible speed, if the engine and the spacecraft are still built according to the previous ideas, there is no need for anything else, this huge force is enough to give the spacecraft Ripped smash. "

"The greater the power, the more powerful the structure and the body to support it. Only by using high-strength materials, and then using the overall casting, and then hollowing out to build it is the most reliable and safest."

"The more parts there are, the worse its safety and reliability, and the easier it is to face problems in the face of strong power."

Qin Yi said with a smile.

Interstellar HNA has just begun. Everyone has no experience in building spaceships and space warships that can sail in the interstellar space. They still stay in the old mode of thinking.

In fact, hundreds of years ago, in the era of great sailing on the earth, in order to be able to create bigger and stronger warships and sea boats ~ lightnovelpub.net ~ they cut almost all large trees in Europe Refined.

In the era of making ships with wood, if you want to build a good ship and a powerful warship, the most important thing is the keel of the ship, and the keel manufacturing requires large trees. The bigger the ship, the keel The bigger.

In Europe at that time, there were many firs, pines, and the best teak. These trees were some good wood for shipbuilding. The most precious teak was used to make the keel and deck of the ship.

Larger teak can be used to make larger ships, which is also more expensive and very valuable.

At the same time, the Huaxia side was in the Ming Dynasty. Despite Zheng He's great voyage to the western seas, because the wood used for shipbuilding was very difficult to find at the time, all of them needed to be found from Yungui River, Hainan and other places to make large trees. In disguise, the cost of this shipbuilding was very high. From this perspective, it also basically hindered the development of China's navigation industry at the time.

Because no suitable wood can be found, it is impossible to build a powerful ship. Even if it can be built, the cost is very high. A piece of wood that can be used to keel is too expensive.

情况 The situation is a bit like that at that time. The second-generation anti-gravity engine is very powerful. It requires the spacecraft to have a strong structure and support. Otherwise, the spacecraft cannot support it under the tearing of such terrible forces.
