Some are similar to Iron Man's skeleton armor, suitcase armor, and so on.
Chen Nuo carefully looked at the information of the power armor, secretly thinking about the feasibility.
Power armor consists of one set of inner and outer core systems and ten sets of end systems.
The ten sets of terminal systems are: energy, transmission, armor, skeleton, external connection, weapon, perception, master control, manipulation, life support and other systems.
The energy system is the core of the entire mecha. Without energy, the mecha cannot move. The energy system can be solved with current technology, such as lithium-sulfur batteries. Although the battery density may not allow the mecha to fly, normal activities And short fights are enough.
To put it bluntly, the transmission system is the carrier and transmission of energy. There are too many superconductors that can be used.
The skeleton system is equivalent to the skin and muscles of the mecha, which can be used by his high-strength light alloy steel, and small firepower such as bullets and RPGs cannot damage the mecha.
Perception systems, such as temperature, pressure, speed measurement, EMP, vision, communication, hearing, etc., can be processed with infrared, small radar, thermal imaging and other equipment, coupled with carbon-based chips;
The control system, in simple terms, is how the mecha moves, such as raising legs, raising hands, etc. This can use a virtual reality helmet to control the movement of the mecha with brain waves, and there is no delay in these.
The life support system is about how to prevent the driver from overloading when accelerating, eating and drinking, extinguishing fires, escaping, etc., and how to absorb shocks when being attacked by heavy weapons to prevent the driver from being shocked to death.
As for the weapon system, you can use some plug-ins, or equip it with a long sword and shield made of alloy steel. The long sword attacks and the shield defends.
With the strength of alloy steel, driven by the power system of the mecha, a tank or something can be smashed with a single sword.
Chapter 476
Power system lithium-sulfur battery;
Skeleton system high-strength light alloy steel;
Perception system infrared, radar;
Control system virtual helmet;
Chen Nuo wrote down the ten end systems on the power armor, and the corresponding solutions.
Seeing this, Chen Nuo suddenly realized that some things needed for power armor have basically been completed in the rewards drawn earlier.
He has always had the feeling that the system is playing a big game, which was originally prepared for the mecha.
With accurate drawings and technical information, as long as other parts are made, the rest is the problem of assembly.
Chen Nuo carefully looked at the technical information, thinking about what else to prepare now.
After another hour, Chen Nuo had a good understanding of the entire armor.
In the whole system, what he is most interested in is the life support system. How this system allows the driver to resist overload when accelerating, eat and drink, scatter, extinguish fire, escape and so on.
Other functions in this system are secondary, but this anti-overload is extremely important. It can be used not only on mechs, but also on fighter planes and spaceships.
A professionally trained pilot can withstand a load of 9 G, and an aerobatic pilot can withstand a maximum of 12 G, which is already an extreme value, and if it is higher, there will be physiological reactions such as black vision.
What is the concept of a load of 9 G? When a large roller coaster dives, the load is between 2.5-3G, and 9 G is equivalent to bearing 9 times its own weight.
However, the anti-load suit provided by the system can allow the pilot to normally withstand 15 G, and withstand 3 G within 16 seconds of instant acceleration. If this is said, it will directly break the cognition of all astronauts.
Seeing this, Chen Nuo thought, since the life support system has anti-load devices, it means that this set of mechs can fly, otherwise it is impossible to use anti-load suits no matter how fast they are on land.
Thinking of this, Chen Nuo went back to look at the design drawing of the entire mech, and slowly he found that this set of armor with a height of more than three meters was hollow in the middle of the palms, elbows, knee joints, back, and soles of the feet. .
This means that there should be a propulsion system for the armor to fly, but this armor system does not provide it.
What kind of pusher to use in such a small space?
If engines such as rockets and airplanes are used, the volume of the armor needs to be increased, but as the volume increases, the weight increases, and the fuel to be carried increases. How to achieve balance is also a problem.
If it is an external engine, it will not work if it is damaged in battle. The only way is to embed the engine in the armor, which requires the miniaturization of the engine.
After thinking for a while, Chen Nuo wrote down the Hall thruster, ion thruster, etc. on the paper;
After sorting out the armor, Chen Nuo began to think about what needs to be made up with the current technology.
The first is the power system. Although there are lithium-sulfur batteries now, it is far from enough. According to the description of a 100 kWh battery, when the armor reaches its limit state, it takes at most 20 minutes.
But this can be solved by using an external battery compartment. Use the battery compartment during the operation, and abandon the battery compartment when you reach the goal, and use your own battery to fight.
In his mind, he ruled out the existing energy systems one by one, and finally wrote down several backup options such as lithium-air batteries and small-scale controllable nuclear fusion.
The second is the accuracy of the parts of the mecha.
Judging from the drawings and requirements of the mech, only a machine tool with a tolerance level of IT2 can truly produce a set of qualified machine tools.
Because the precision of the gear meshing device required by the mechanical arm is extremely high, the precision is not enough, and the movement is a bit off, which may cause a large error.
But for the prototype machine, the tolerance level can be IT5.
The third is the propulsion system. If the power armor is only used on land, its value will be greatly reduced. It is also necessary to equip the armor with a propeller to make it fly.
After Chen Nuo went through all the information of the entire set of power armor, he finally breathed a sigh of relief.
After leaving the study, after having dinner and resting for a while, he entered the study again. He wanted to get out the blueprint of the armor.
The drawings include not only two-dimensional floor plans, but also three-dimensional ones. Chen Nuo had no choice but to download SolidEdge. Although he has never learned drawing software, he has a learning card and read the operation manual for two or three hours. Just learned the solidedge operation.
Two hours later, Chen Nuozhi drew 42 parts, which can make up to seven or eight thousand parts for a whole suit of armor.
According to painting 4 hours a day, he needs nearly two months to finish painting.
This is just an ideal state. For some parts with complex structures, he can only draw one in half an hour.
Calculated in this way, it would take three to four months just for the drawings.
Chen Nuo couldn't help complaining: System, you are really a fool, with so many drawings and materials, why don't you transfer them to the computer like you gave me No. [-] brain?
You didn't ask!
Except for the lottery draw and the release of tasks, the system that had been silent all this time actually made a sound.
Fuck, as a system that assists me, shouldn't you understand the master's thoughts?
I am working on blueprints every day now, do I need to do other research?
Give me a quick word, can you get it directly on the computer now?
Chen Nuo babbled on for two to three minutes, but the system ignored him at all.
Forget it, do it yourself, draw the picture again, and understand it more deeply!
Thinking of this, the resentment in Chen Nuo's heart dissipated a lot.
Chen Nuo didn't go to bed until two or three o'clock in the morning.
Early the next morning, Chen Nuo went to the future technology laboratory, and then went down to the underground lithium-air battery laboratory.
If the energy of the power armor is not enough, then use lithium-air batteries. After all, the energy density of lithium-air batteries is four times that of lithium-sulfur batteries, which is enough to support the armor's extreme battle for an hour.
Under the attack of modern warfare and large-scale firepower, more than an hour of fighting is enough to clear an area.
Professor Chen, why are you here?
As soon as Chen Nuo arrived at the lithium-air battery laboratory, he met Zhang Yueqi, the deputy team leader of the project.
Has lithium-air battery progressed?
With some eyebrows!
Have?
Hearing Zhang Yueqi's answer, Chen Nuo was a little surprised.
Lithium-air batteries are difficult to say, but simple and simple. The working principle is that the lithium in the negative electrode reacts with the oxygen in the positive electrode to generate lithium peroxide, and a current appears in the external circuit. When charging, the lithium peroxide is decomposed into lithium and oxygen. .
But the difficulty is how to screen pure oxygen?Install an oxygen cylinder, that is a lithium air bomb, which is more powerful than TNT explosives. Once it explodes, the people in the car will die.
Secondly, lithium hydroxide, a solid reaction product, will accumulate on the positive electrode, blocking the contact between the electrolyte and the air, thereby causing the discharge to stop.
Even though Chen Nuo got a guidebook on lithium-air battery architecture technology, it is the same as not having it for this researcher to study.
Chapter 477 Breakthrough of lithium-air battery
Which difficulty has been overcome?
Chen Nuo took the teacup from Professor Zhang Yueqi and asked casually.
We have made some breakthroughs in the screening of oxygen molecules.
Zhang Yueqi walked to the side of the bookshelf, took out a document and handed it over.
Chen Nuo took the file and read it slowly.
【Polymer membrane for mixed gas screening, dissolution and separation technology】
Half an hour later, Chen Nuo put down the materials, all thoughts in his eyes.
This technology is to use polymers to make a large net, but the mesh of this net is relatively small, allowing only smaller molecules to pass through the membrane and intercepting larger molecules.
气体的分子大小是核心，如比如H2是0.289nm，CO2是0.33，O2是0.346
Their membrane filtered to the end, leaving only two molecules, hydrogen and oxygen.
Hydrogen and oxygen can also be produced by using water and electrolysis, but this method is basically impossible to experiment in batteries, the gas generation is too slow, and the current generated by the reaction with lithium is too small to start the car at all.
Moreover, the device occupies a large volume, and it is not easy to collect hydrogen and oxygen, and it may explode if it is not done well.
The principle of Zhang Yueqi and others is to use the principle of air entering the five-layer membrane of the alveoli for screening.
Professor Chen, after this layer of polymer film, we put your film made of multi-carbon nanospheres into it after multi-layer dislocation and stacking. Now the overall oxygen purity can reach about 96.8%.
In the next step, we consider two methods, one is high pressure, using the boiling point separation of two gases, and the other is using gas absorption or reaction to make the oxygen purity reach 99.6% pure oxygen state.
Pretty!
Chen Nuo slapped his thigh fiercely.
I never expected that the lithium-air project team could really make a big breakthrough. If the oxygen screening is solved, then basically the lithium-air battery can be used. Lithium hydroxide can be piled up if it needs to be piled up. It is nothing more than the number of cycles. .
It may take time to solve another difficulty for commercial use, but it is definitely possible to use it in power armor. At worst, it is not difficult to dispatch solid lithium once.
Professor Zhang, you have done me a great favor. If lithium-air batteries can be produced, academicians can be expected.
academician?
Zhang Yueqi smiled wryly. He is already the top professor in the field of energy storage batteries in China. He was co-opted for three consecutive years and was not even nominated for various reasons.
Lithium-air batteries are very powerful, but the possibility of being elected as an academician based on this is a little bit worse.
Don't worry, I said yes!
Chen Nuo smiled mysteriously.
The lithium-air battery alone is a little bit worse, but who told him that the power system of this armor just lacks this thing.
Once the armor is out, with lithium-air batteries, Xia Guo's individual combat is definitely the first in all, which is very important to Xia Guo's military strength.
With armor made of high-strength light alloy steel, local tanks are completely useless.
It is said that instead of looking at the monk's face and the Buddha's face, Chen Nuo will find a few academicians to help, and the problem should not be too big.
There are several academicians in the future science and technology laboratory, which can be regarded as his selfishness.
Zhang Yueqi looked at Chen Nuo and opened his mouth, wanting to say something but didn't know where to start.
Chen Nuo himself is not an academician, but now he told him that his academician is promising, which is a bit funny no matter how you look at it.
But he knew that next year's co-option of academicians will be 100% Chen Nuo.
He heard from gossip that the Academy of Sciences and the Academy of Engineering are arguing over which academy Chen Nuo will enter next year.
This is really the death of drought and the death of flood.
After thinking about it, Zhang Yueqi calmed down. Before, he might still have a strong heart to select academicians, but now after Chen Nuo's future technology experiment, he is not so attached to academicians.
The academic world is largely managed in accordance with the administrative model, the relationship between superiors and subordinates, academicians are top scientific research leaders, their words are the golden rule, and it is easier to win funding, etc.;
But in Future Technology, as long as your project passes the evaluation, you can spend as much as you want. For example, this lithium-air battery has burned [-] to [-] million since the project was established.
If you want money, just make an application. May I ask which laboratory in Xiaguo can do this?
Moreover, the scientific research environment, scientific research equipment, salary and treatment here are far worse than those academicians.
Besides, with Chen Nuo as a big boss, no academician would dictate their experiments.
Zhang Yueqi shook his head slightly, and said, "Professor Chen, let me take you around the laboratory to cheer everyone up, and take a look at our experiment by the way, how about it?"
go!
