Doomsday Bunker Upgrade

Back in the shelter, Chen Xin was busy miniaturizing the isotope thermoelectric battery, and he was also seriously thinking about what to do with the exoskeleton protective suit.

The manufacture of exoskeletons is a very simple matter for Chen Xin. In fact, even for the current Yan Kingdom, it is not difficult to manufacture a set of exoskeletons.

Before the disaster, various exoskeletons that had entered the practical stage had been put into use, not only in the army, but even the takeaway courier brother already had experimental exoskeletons.

However, this kind of exoskeleton is a passive exoskeleton. In short, it is a load-bearing bracket without a power source. Through scientific ergonomic design, it can effectively support heavy objects and reduce the physical consumption of users. It belongs to a kind of power-assisted equipment.

However, this exoskeleton obviously cannot meet Chen Xin's requirements, and he does not need to work hard to develop this kind of thing, the country already has ready-made things to use.

The exoskeleton that Chen Xin wants to develop should be called a mechanical exoskeleton or a power exoskeleton. It is a mechanical device made of a steel frame and can be donned by a person. This equipment can provide additional energy for limb movement.

This kind of equipment is common in various sci-fi works, such as the armor of fifty brothers in "StarCraft", the Mark series iron suit in "Iron Man", and the armor on Tom in "Edge of Tomorrow". Sets of equipment, the ugly and cute T series in the "Fallout" series, the Thor's Hammer of the Rispartan warriors in the "Halo" series, etc...

These are the exoskeleton devices that people think of, or more simply called power armor.

In fact, strictly speaking, there is not much difference between the two in essence, or the exoskeleton just lacks power armor with more solid protection, and power armor is an exoskeleton with more comprehensive protection.

The concept of this kind of equipment was proposed in the Federation in 1960. After years of research, various related technologies and research and development ideas about exoskeletons have long been proven. What is really left is the hard bones that cannot be solved by modern technology. .

There are two most critical issues in this. The first is how to control the exoskeleton in the human-computer interaction mode, and the second is the power source of the exoskeleton.

The choice of the way of human-computer interaction in the development of exoskeleton is not a troublesome problem, but it is not so easy to solve.

And the power source is the obstacle that plagues the exoskeleton into the practical and promotion stage. It can be said that one of the biggest difficulties in exoskeleton research and development is the power source problem.

In order to solve the power problem, someone even proposed to make a wired version of the power exoskeleton that drags a cable like EVA.

However, these problems are not difficult for Chen Xin. Take a few steel pipes to weld a movable shelf, arrange a mechanical transmission, and then connect a battery. It does not even need hydraulic assistance. A set of the most primitive power exoskeleton is even made. After coming out, the work after that can be completely handed over to the system, and Chen Xin only needs to upgrade.

But this is not what Chen Xin wants, or this time Chen Xin needs to consider more issues and factors.

Because this exoskeleton protective suit is designed for civilian use, it is mainly provided to construction workers and those who need to leave the shelter to work, providing them with warmth and protection in severe cold and harsh environments, as well as a certain degree of boosting.

Therefore, this set of exoskeleton protective clothing mainly focuses on protection and warmth. It does not need to be too strong for boosting, and because it is to be mass-produced and put into use, the cost of production and maintenance and the convenience of use should be put considered in the first place.

It is very simple for Chen Xin to make a set by himself. He can just pile up survival points regardless of the cost. Even if he finally piles up a nano-armor like Mark85, it is not a problem, but this is limited to his own use or small batch supply. Used by people in shelters.

Large-scale production of exoskeleton protective clothing is not a matter of a few sets or dozens of sets, or even hundreds of thousands or millions. There are still hundreds of millions of people in the country, even if only one-tenth of the people need to use exoskeleton protective clothing It is also the number of tens of millions of sets. If the cost and maintenance issues are not considered, even a country like the Yan Kingdom cannot afford such a huge expenditure.

This is also the reason why Chen Xin gave up the idea of ​​​​creating a power armor with full body protection. It is not that it cannot be done, nor that it is too dangerous for civilian use, but that there is no basis for widespread popularization.

In fact, in Chen Xin's vision, such a set of exoskeleton protective clothing can't even use a miniaturized isotope thermoelectric battery. It is enough to install a rechargeable battery that can run it for dozens of hours. After all, its main function is to keep warm and protect.

Keeping warm is easy to achieve. There is ready-made technology in the pilot's anti-G suit. It is enough to add resistance wires like an electric blanket, so that the protective suit has an electric heating function. The only problem is whether the battery can bear it.

And according to Chen Xin's judgment, in the future, this method of electric heating will become the main thermal clothing for human beings together with synthetic fiber clothing, because the traditional natural fabrics, cotton, linen and wool have lost most of the source of raw materials, even if There is still some production capacity that can be preserved, which is not something that ordinary shelter residents can care about.

Therefore, in terms of protective clothing for such a set of exoskeleton protective clothing, Chen Xin intends to use one-piece synthetic fiber clothing with electric heating wires for heating to ensure the protective clothing's resistance to cold.

After all, this is a relatively lower cost, more convenient way to obtain raw materials, and more convenient for production.

It has also become difficult to obtain raw materials for the duck down and cotton filling methods in the past, so instead of using the filling method in the past to keep warm, it is better to put electric blankets directly on the body.

As long as the thermal insulation performance of the outer layer structure is good enough, and the electric heating method is effective enough, even at a low temperature of minus tens of degrees, such a set of exoskeleton protective clothing is enough to ensure that the wearer will not be frostbitten.

Coupled with a full-coverage helmet connected to an oxygen supply device, it is more than enough to protect the wearer from various harmful environments.

As for the part of the exoskeleton, it can be relatively simple, and it can completely use the existing unrelated exoskeleton with relatively mature technology as the basis, or even directly use the unrelated exoskeleton as the ordinary civilian version, and add the power system as an upgraded version to provide the building Workers and other people who require heavy physical labor.

Chen Xin, the battery part, intends to develop a high-capacity high-performance battery that can be recharged repeatedly as the power source for the exoskeleton suit after completing the miniaturized isotope thermoelectric battery.

On the one hand, exoskeleton protective clothing is ordinary civilian equipment, and it does not require long-term power supply. In addition, isotope thermoelectric batteries are radioactive elements anyway, and there will be certain safety problems when used for civilian use.

On the other hand, it is also due to cost considerations. Although the production cost of high-performance batteries is also not low, it is still much cheaper than the production of isotope thermoelectric batteries.

Therefore, after comprehensively considering various factors, Chen Xin also had a concept on how to design this exoskeleton protective suit.

I found a set of old work clothes that I got from my father when I was still working, dug out the electric blanket that was no longer useful after installing the ground source heat pump, and went to the warehouse to get the exoskeleton needed. The metal material, Chen Xin sat in front of the workbench, ready to make a prototype first.

Taking old work clothes as the main body and adding electric blankets as materials, a set of protective clothing with electric heating function will be freshly released after Chen Xin confirms the upgrade.

After that, the battery, exoskeleton and helmet need to be installed.

Among the three batteries, Chen Xin still uses batteries, but this time he upgraded the batteries so that they can be recharged quickly and repeatedly, instead of making them into high-durability nuclear batteries.

As for the helmet, Chen Xin only intends to make a simplified cover for the time being. As for whether to add other functions in the future, it is a matter of follow-up research and development. As a prototype, it is enough to seal, provide oxygen and block the cold outside.
