Chapter 248 It’s quite satisfactory

When it comes to excavator technology, a magical figure will appear in people's minds, but there is no such school in the radiation world, so Dong Chen taught himself.

Fortunately, the excavator was made by Dong Chen. Dong Chen knew the operating mechanism of the excavator quite well, which was the lever principle used. Moreover, during the manufacturing process, he also deliberately simplified the mechanical devices and operating steps.

Dong Chen didn't need to drive the excavator to perform a full Thomas rotation, nor did he need to perform any fancy operations. He only needed to be able to dig out large rocks and dig away broken bricks and cement rubble.

Therefore, it was very simple for Dong Chen to learn how to use the excavator he built. At least after one day, Dong Chen could use it very smoothly.

This big shovel can dig much faster than Dong Chen and the robot, especially when encountering piles of rubble. Some large pieces of debris, such as some floor slabs or large pieces of cement, could be moved away by Dong Chen wearing power armor and using ZS001 to expend some power.

But for piles of soil or debris, Dong Chen and the robot have no choice but to do it bit by bit. This is why Dong Chen insists on taking up time to build an excavator. A shovel can push Dong Chen down. Dig with a robot for ten minutes with a shovel.

Not to mention, since both people are driving excavators, the progress of the project will be faster.

Those excavated ruins did not disappoint Dong Chen. According to the setting of this game, the nuclear attack came suddenly, and they had no time to transfer some important information and data.

The beginning of the game also proved that the residents obviously didn't know anything. The evacuation was very sudden and panicked, and the information was also thrown into the ruins, so Dong Chen found a lot of information in the ruins.

Dong Chen mainly cleaned up the ruins of the Arc Jet System Research Institute and the Poseidon Energy Turbine Research Institute, which included the high-tech engine technology that Dong Chen needed most. Dong Chen found a large amount of technical information in the cleared ruins. .

This information includes vehicle engines and aircraft engines. Most of them are energy engine technologies, that is, electric propulsion systems. There are much less engine technologies that use liquid fuel for propulsion. But think about the background setting of this game. I'll be relieved.

Although there is also research on electric engines in the real world, people's demand for electric engines is not urgent because there is still a large amount of fossil energy to supply and use, and due to technical constraints, especially the problem of how to continuously supply power has not been solved. , so this technology is not developing rapidly.

But it's different in the radiation world. Fossil energy here has been in short supply to a dangerous level. Therefore, while scientists here are trying their best to improve and optimize bioenergy engines, they are also constantly conquering electric propulsion engine technology.

And because they have the killer weapon of nuclear fusion, they have developed quite rapidly in the field of electric propulsion. Various electric propulsion technologies have made good progress, and their practical applications have been very successful.

There is no way, people will not explode unless they are pushed to the point of despair.

It is said that war is the ferment that promotes technological progress. That is because both sides of the war do not want to die, so they work hard to develop new technologies and create more high-tech weapons to save lives. The energy shortage set in the game is also a factor. A small leather whip, a strong whip will give you motivation.

Ion thruster is one of these. In the real world, we have given it a definition, that is, it is a type of space electric propulsion technology. Its characteristics are small thrust and high specific impulse, and can be widely used in space propulsion. Such as spacecraft attitude control, position maintenance, orbital maneuvering and interstellar flight, etc.

Compared with traditional chemical propulsion methods, ion thrusters require a small working fluid mass and are very efficient. They are a power device suitable for long-distance navigation in the universe.

Yes, the thrust is too small, so don't even think about it inside the atmosphere, but that's not what the information Dong Chen dug out of the ruins said.

It was not that Dong Chen had never questioned the authenticity of the technology in these game worlds, but after Dong Chen obtained the first information and verified it, Dong Chen dispelled such doubts.

The initial thrust of the ion thruster was indeed very small, so small that it could only push a piece of paper. It's the same in the radiation world. They did a lot of experiments at first, until they used a mature nuclear fusion device.

Currently, in the real world, solar panels provide energy for ion thrusters on spacecrafts. Their power is very small and the power they provide is limited, so the ion thrusters can only muddle along.

But the nuclear fusion device is a violent big thing, which can provide very high power to the ion thruster, and can also provide a steady stream of energy. Therefore, the ion thruster using nuclear fusion energy can directly ionize the air, and then provide a very huge thrust.

However, this powerful ionized air process has a characteristic, that is, it will make a huge sound. This is actually not a big deal. Other aircraft will also make a huge roar when flying, but the sound of this ion thruster Not the average size.

Fortunately, this is an early ion engine in the radiation world. Just because they have nuclear fusion as energy source, they succeeded early. After subsequent optimization and upgrades, the sound has become much smaller, at least less than the sound of air friction.

In the later stage, they have more advanced research directions, such as making it faster, more responsive, etc., so that it will not be outdated when it flies out of the solar system, but the "world's nuclear level" is under research.

Although it is a pity, Dong Chen is already very satisfied. With this thing, Dong Chen can build a spaceship that takes off directly from the ground. Maybe he can try building a smaller aerospace plane first.

Larger spaceships may have to wait, because the evil game settings are here again. There is no mention of large spaceships in either the game plot or the game background settings, so there are no large spaceships here at all. any information.

In fact, even the information on aerospace aircraft is not complete here, because here are only two places that develop propulsion engines. They only have some basic data on aerospace aircraft to ensure that the ion thrusters they manufacture are suitable for use on aerospace aircraft. .

So no matter what he wants to build, Dong Chen has to study it carefully because there is no detailed data.

In addition to these, there is no satellite data here because there is no aerospace research center here, so Dong Chen needs to think carefully about this, and maybe collect data in the real world.

What worries Dong Chen the most is the issue of submarines. Dong Chen found relevant information in the ruins of several large shipyards. In addition to these, the information obtained from the Yangtze River No. 31 submarine also contains a large number of submarines. data, so the construction of the submarine should not be a big problem.

In this way, Dong Chen spent more than a year cleaning up the ruins, organizing materials, studying, cooking and exercising.

Although all this information will be put into No. 1's database, and a lot of it can be produced directly with a little bit of organization, Dong Chen still hopes to put some things in his mind and understand them thoroughly.

Not only can this help you feel confident, but you can also pretend to be useful.
