In the Robot plan, there are several sets of almost perfect designs for the shape scheme of the metal exoskeleton. But even if the shape of the metal exoskeleton is solved, the key is how to design the drive mode of the metal exoskeleton, which has become a big problem!

In the field of metal exoskeletons, there are currently two power drive methods.

The first is pneumatic, that is, the way of gas pressure to drive the movement of various mechanical parts. The pneumatic solution has some advantages, such as a lower body weight and more flexible force output. However, there are also weaknesses in the pneumatic scheme, the most serious of which is the problem of pneumatic pressure, the volume of the gas can be highly compressed, which is a considerable drawback.

The second drive scheme is hydraulic drive, which is currently the mainstream and is the main research scheme for the study of metal exoskeleton mechanisms, and has a relatively mature technique.

The drive scheme is solved, and a new problem is faced, that is, the problem of energy storage!

Due to the limitations of its appearance, metal exoskeletons cannot carry large amounts of energy like airplanes and armored tanks.

The humanoid shape is destined to carry only a small amount of energy. This is true for both electrical and chemical energy.

On the issue of energy, Robot has given three energy options in its plan. The first is a chemical energy consisting of liquid hydrogen and liquid oxygen, which has three times the calorific value of gasoline. That is, hydrogen of the same mass produces three times as much energy as gasoline. However, liquid hydrogen also has a weakness, that is, the density of liquid hydrogen is too low, only 70.8KG/m3.

The second energy solution. It is a high-performance lithium battery, and this solution is simple. However, due to the limitations of lithium battery materials and the technical problems of the process, there will be less energy storage. In short, combat time will be quite scarce.

The third option, the most common and the most basic energy solution, uses aviation-grade gasoline as an energy source. Although the calorific value of aviation-grade gasoline is not high, the density of aviation-grade gasoline reaches 750KG/m3. In the same volume, the mass of aviation-grade gasoline is 10.6 times that of liquid hydrogen!

With such a huge disparity in quality, even liquid hydrogen has three times the calorific value of gasoline. Nor can it be compared with the total calorific value of gasoline. The calorific value of aviation-grade gasoline reaches 48,000,000 joules per kilogram, which is equivalent to 3,600,000 joules per kilowatt-hour.

If you don't calculate the energy loss, one kilogram of aviation gasoline produces about 13.33 times more energy than one kilowatt-hour of electricity.

It is precisely because of such a powerful advantage of aviation gasoline that it is currently being studied. Aviation gasoline was considered to be the first research energy source.

Dong Guoguo also did not hesitate to choose aviation gasoline. As the first research energy.

The eldest young master of the Rongcheng Military Region, Li Yuan looked at the design on Dong Guoguo's computer. And asked, "Uncle Dong." Why is this armor-like armor with a big backpack on the back? Such a design is so ugly! ”

Dong Guoguo ignored Li Yuan, this kid probably had to keep asking, so he could only explain helplessly: "That's the fuel tank!" If the design of the fuel tank is canceled, the entire metal exoskeleton. It doesn't work at all! ”

Li Yuan was pleasantly surprised: "Uncle Dong, do you mean that the metal exoskeleton is about to be developed and can it be put into practical use?" ”

Dong Guoguo shook his head. "The main body of the metal exoskeleton is about to be completed, but its operating system needs to be completed by the boss himself. Without an operating system, the metal exoskeleton is just an ornament! ”

What Dong Guoguo said is not bad!

In the Robot plan, all the conditions of the metal exoskeleton that had already been designed, including the overall shape, the individual specifications of each component, and even the miniature internal combustion engine, were all preliminarily prepared.

But the only thing missing is the operating system!

How important is the operating system? As a simple example, let's say a personal computer with extremely powerful hardware configurations, but no Windows operating system, no other operating system, what good is it?

It is estimated that it has no effect except as a decoration!

"Uncle Dong, are you saying that as long as Shi Lei makes the operating system of the metal exoskeleton, the metal exoskeleton can be put into practical testing?" Li Yuan asked excitedly.

"Not yet, as for the material aspects of the fuel tank, further testing is needed. Since the fuel tank is back-mounted, it has to assume not only the function of the fuel tank, but also the function of defensive armor. When you are attacked by sniper rifles, including anti-materiel sniper rifles, try to block the bullets as much as possible! ”

Li Yuan frowned, he definitely knew a lot more about the anti-materiel sniper rifle than Dong Guoguo. Judging from the name, since it is already called an anti-materiel weapon, its power must not be underestimated.

Anti-materiel sniper rifles, most of the time used to hit armored vehicles and even attack tanks. With such a powerful attack power, even the armor of the metal exoskeleton can defend against it, but the super impact force alone will make the combatants inside incapacitated.

"Uncle Dong, I'm afraid it won't be able to block the attack of the anti-materiel sniper rifle!" Li Yuan said it directly.

Dong Guoguo looked at Li Yuan with a smile, "Li Yuan, do you think I don't know the truth?" I'm just thinking about how to avoid the explosion of the fuel tank after fending off an anti-materiel sniper rifle attack! ”

"Oh!" Li Yuan scratched his head in embarrassment, "Uncle Dong, how big have you designed the fuel tank?" If the fuel is not enough, the combat power of the metal exoskeleton is negligible! ”

Dong Guoguo called up the design plan of the fuel tank on the computer, and said to Li Yuan: "See for yourself!" After reading it, hurry up and get out, don't bother me! ”

Li Yuan's eyes rolled, but he was not angry, staring at the detailed parameters on the computer screen.

The length is 70cm, the width is 50cm, and the thickness is 10cm, so the total capacity is not large! Li Yuan secretly calculated in his heart, the total capacity is the length times the width by the height, which is equal to the standard 35 liters.

"Uncle Dong, the fuel tank is only 35 liters, will it be too small?" Li Yuan asked suspiciously.

Dong Guoguo rubbed his temples, if it weren't for Li Yuan's special identity, Dong Guoguo would have ordered Li Yuan, this kid, to get out!

"Li Yuan, do you know what the concept of 35 liters of Lu Dao is? Let me tell you, the fuel tank capacity of the average small car is only about 35 liters. The fuel consumption of a 1.4 displacement car is about 7 liters per 100 kilometers, which means that a fuel tank of 35 liters is enough to supply a car for 500 kilometers. Isn't that enough? The metal exoskeleton is equipped with such a fuel tank, which can support even the most intense combat situations for more than 4 hours. In non-combat situations, at least 12 hours of operation can be achieved. ”

Dong Guoguo took a breath and continued to speak: "Don't ask me why I don't continue to increase the size!" The size of the fuel tank, after repeated calculations, the above size is the most suitable, will not affect the metal exoskeleton combat, and fully meet the requirements of conventional combat. If you want to ask what is only 10 centimeters thick, can you continue to increase some more. Then let me tell you, in terms of thickness, you also need to load a 4cm alloy armor, as well as a 2cm rubber shock-absorbing compartment, which cannot increase the thickness! ”

Li Yuan pretended to understand, "Uncle Dong, I understand!" ”

"Get out of here if you understand, don't delay my research work!" Dong Guoguo said politely.

Li Yuan walked to the research rooms of several other experts in a gloomy manner, ready to ask about the situation of the other experts. Due to the protection and the planning of the metal exoskeleton, Li Yuan was designated by the Rongcheng Military Region to supervise the planning of the metal exoskeleton.

Li Yuan almost didn't understand anything about the metal exoskeleton plan, and his only use in the research room was to be idle!

In the aerodynamics laboratory, Professor Song En, who is like a stuffy gourd, was selected by Dong Guoguo as the chief expert of the aerodynamics laboratory.

Li Yuan walked into the aerodynamics laboratory, and saw that Professor Song En was testing the aerodynamic flow linearity of some parts of the metal exoskeleton, and he asked excitedly: "Professor Song, how is the aerodynamic performance of the metal exoskeleton?" ”

Song Eun is a standard stuffy gourd, and when Li Yuan asks him anything, he won't answer at all.

Li Yuan asked a few more questions to himself, and after finding that Song En did not answer, he could only go to other laboratories.

The mechanical shock absorption laboratory presided over by Professor Jinda is improving the mechanical structure of the metal exoskeleton and striving to achieve better shock absorption effect.

Li Yuan, a decrepit person, had just walked into the mechanical shock absorption laboratory, Jinda generally did not smile, he looked at Li Yuan with a serious expression, and said directly: "Li Yuan, you go to Lu Fang to play!" ”

"Professor Jin, I'll see if you're making any progress!" Li Yuan said with a dead face, wanting to infiltrate the mechanical shock absorption laboratory and see the experiments they were doing.

Jinda snorted lightly, "Let's play!" We don't have time for you! ”

Li Yuan had no choice but to go to the mechanical power research room in charge of the good old man Lu Fang. Although Lu Fang has a goatee and looks more sinister and cunning, Lu Fang is a good man.

Walking into the mechanical power laboratory, Lu Fang was testing the miniature internal combustion engine that was ready to be installed inside the metal exoskeleton. Space is limited in metal exoskeletons, and every interior space must be fully utilized.

In the case of limited volume, how to explode more powerful power under the same volume conditions is something that Lu Fang needs to consider.

The power system of the metal exoskeleton is definitely the top priority, without a strong power system, the combat ability of the metal exoskeleton is a small scum!

If you want to make a metal exoskeleton produce powerful combat capabilities, you must have a strong power core. Just like a car, can a 1.0 displacement car compare with a 3.0 displacement car in terms of acceleration, top speed, and load capacity?

Li Chai stood beside Lu Fang and asked with a smile, "Professor Lu, how is the engine of the metal exoskeleton prepared?" ”.
