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, and Dong Chen still understands the operating mechanism of the excavator, which is the principle of lever used, and in the manufacturing process, he also deliberately simplified the mechanical devices and operation steps.

Dong Chen doesn't need to drive the excavator to spin Thomas all around, and he doesn't need to perform any sassy operations, he just needs to dig up the big pieces of rock, and dig up the broken bricks and cement ruins.

Therefore, it is very simple for Dong Chen to learn how to use the excavator he built, at least after a day, Dong Chen will use it very slippery.

This big shovel can dig much faster than Dong Chen and the robot, especially when encountering a pile of rubble. Some large pieces of ruins, like some floor slabs or large pieces of cement or something, Dong Chen can also move away with some power in power armor and ZS001.

But for the pile of soil or debris, Dong Chen and the robot have no choice, they can only come little by little, which is why Dong Chen has to occupy time to build an excavator, a shovel can top Dong Chen and the robot with a shovel to dig for ten minutes.

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

Those dug up ruins really did not disappoint Dong Chen, according to the setting of this game, this nuclear strike was sudden, and they didn't have time to transfer some important information and data at all.

And the beginning of the game also proves that the residents obviously don't know anything, the evacuation situation is very sudden and panicked, and those materials will also be smashed 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, and Dong Chen found a large number of technical materials in the cleaned up ruins.

This includes engines for vehicles and aircraft, and most of them are energy engine technologies, i.e., electric propulsion systems, and there are far fewer engines that use liquid fuel for propulsion, but it's relieving to think about the game's setting.

Although there are also studies on electric engines in the real world, people's demand for electric engines is not urgent, because there are still a large number of fossil energy sources to supply and use, and due to the constraints of technical conditions, especially how to continue to supply power, this technology has not developed rapidly.

But in the world of radiation, fossil energy has been scarce to a dangerous point, so scientists here are trying to improve and optimize the bioenergy engine, and they are also constantly tackling electric propulsion engine technology.

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

There is no way, people will not break out if they are not forced to the Jedi.

It is said that war is a leavening agent to promote scientific and technological progress, and that is because both sides of the war do not want to die, so they are desperately developing new technologies and want to create more high-tech weapons to save their lives.

Ion thruster is one of them, in the real world we have given it a definition, that is, one of the space electric propulsion technology, it is characterized by 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.

Compared with the traditional chemical propulsion method, the ion thruster requires a small working fluid mass and is very efficient, and it is a power unit suitable for long-distance navigation in space.

Yes, the thrust is too small, don't think about it in the atmosphere, but the information that Dong Chen dug up in the ruins doesn't say so.

It's not that Dong Chen hasn't questioned the authenticity of technology in these game worlds, but since the first information Dong Chen got and verified it, Dong Chen dispelled this doubt.

The initial ion thrusters did have very little thrust, so small that they could only push a piece of paper. It's the same in the world of fallout, and they did a lot of experiments at the beginning, until they used a full-fledged nuclear fusion device.

At present, in the real world, the energy provided to the ion thruster on the spacecraft is the solar panel, which has very little power and provides limited power, so the ion thruster can only get by.

But the fusion device is a violent big guy, which can provide very high power to the ion thruster, and can also provide a steady stream of energy, so the ion thruster that uses the fusion energy can directly ionize the air and then provide a very huge thrust.

However, this powerful ionization process has a characteristic, that is, it will make a loud noise, which is actually not a big deal, and other aircraft will also make a loud roar when flying, but the sound of this ion thruster is not ordinary.

Fortunately, this is the early ion engine of the radiation world, but because they have nuclear fusion as an energy source, they succeeded in the early stage, and after later optimization and upgrading, this sound has been much quieter, at least less than the sound of air friction.

In the later stage, they have more clever research directions, such as making it faster, more flexible and so on, so that it will not be outdated when it flies out of the solar system, but it is in the process of "world nuclear level".

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 build a relatively small aerospace plane first.

Larger spaceships may have to wait, because the game setting of all evils is here again, and there is no mention of large spaceships in either the game plot or the game background setting, so here Bengen can't find any information about large spaceships.

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

So no matter what is going to be built, Dong Chen has to study it more carefully here, 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 has to think about this carefully, maybe he will have to collect information in the real world.

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 has a large number of submarine information, so the construction of submersibles should not be a big problem.

In this way, for more than a year this time, Dong Chen spent more than a year cleaning up the ruins, sorting out materials, studying selflessly, cooking and exercising.

Although these materials will be put into the database of No. 1, and there are many materials that can be directly created with a little arrangement, Dong Chen still hopes to put some things in his mind and understand them thoroughly.

In this way, not only can you have a bottom in your heart, but you can also use it.
