Peng Weining saw Zhao Manhong, Shen Yiyi, Liu Yihao, and Wei Yuan being busy there, and felt a little helpless. He is a soldier, even if he is willing to use his life to protect Shen Yiyi, in this field of professional knowledge, he still has no way to help. At this moment, Peng Weining felt that he might not be able to get close to Shen Yiyi's heart in this field in his life.

Peng Weining is lonely at this moment. Because none of the others in this room would have the heart to consider his feelings. Everyone has been occupied by the upcoming research breakthroughs.

Shen carefully inspected the mechanisms on the machine guns one by one. Those organs didn't exist on the first day of her contact, and they were all added by the friends little by little under the guidance of Old Man Zhao in the past few weeks. And these mechanisms are not empty, often each mechanism has several wires or wires connected to it, connected to several other boxes on the ground. In it, the control and actuation units of the "Terminator" system are stored.

Because several units of the whole system are still designed according to modularity, in the process of research, in order to spread out the working surface, the connection of each unit is still wired instead of integrated. Such a design is most efficient in the experimental research phase. Because first, people who can be responsible for different modules can divide labor and cooperate, and carry out multiple work faces at the same time; Second, if something goes wrong with such a design, it can only be partially changed in the area where the problem occurred, without affecting other places, causing the entire research topic to be delayed.

At this moment, Old Man Zhao and Liu Yihao were each holding a pair of pliers, adjusting the steel wire on it in two different positions of the machine gun.

Yes. In order to maintain the sensitivity of the entire "Terminator" system, in the design, in addition to the main load-bearing components, in the non-electronic control part, Shen Yiyi and Liu Yihao discussed and adopted the connection form of steel wire spokes. It's like the drive of a piano. Because of the use of steel wire connection, the mechanical inertia of the whole system is actually reduced, and the design of the spokes can be made with a strong arm of slender steel wire, which greatly reduces the energy consumption during operation. The most feared state of instability for the long straight strip structure is that the entire wire spoke is in a state of tension rather than a state of compression when acting, and the instability of the pressure rod cannot occur here.

Such an ingenious design was completely designed by two college students from Tsinghua University who had not yet graduated, and applied it to this project, and the important thing is that from the beginning of the research to the present, the design of the entire mechanical part has been well verified to ensure the smooth progress of the project. After Zhao Manhong and Old Man Zhao found out, they spoke highly of it. In the process of the project, it is not the first time that Mr. Zhao has given a thumbs up to the team from Tsinghua University this time. And the more such thumbs accumulate, the fiery revolutionary enthusiasm that was once extinguished by Old Man Zhao comes back to life. He had even moved to report to the above and assign these two students to him.

The old man has been in the army for a long time, so his understanding has become a little out of touch with society. He did not yet know that the distribution of college students in the country as a whole had changed radically from before. Now the state no longer allocates college students, and of course, there is no way to specify where college students will go after graduation. So the old man's idea may only be a luxury.

Of course, if it is really specific to Shen Yiyi and Liu Yihao, it is not impossible to ask them to come, but they have to use their brains and turn a corner. Not to mention anything else, Shen Yiyi was originally under the strong request of Comrade Shen Jianguo, and she was a national defense orientation student. As a national defense orientation student, it means that you want to join the army after graduation. This is also joining the army, and it is certainly not impossible to get her to the Capital Military Region. And Old Man Zhao's prestige in the Capital Military Region is still very high, and it is not difficult to use his influence to get this little girl to himself. As for Liu Yihao, he is not a national defense student. He is a high-achieving student who can enter Tsinghua University through the unified recruitment, so it is a bit of a problem to get him directly. However, Liu Yihao can be conscripted into the army through special channels, and then he will be pulled to the Capital Military Region. It's a little bigger, but it's still a way to go. Of course, we are not the Kuomintang, and we don't force the people, but just because Shen Yiyi will definitely enlist in the army after graduation, it is okay to use Liu Yihao's red heart to Yiyi's admiration for Yiyi, and ask him to voluntarily join the army.

It's just that the above theoretically feasible roads for Shen Yiyi and Liu Yihao to come to the Capital Military Region have no hope of being implemented here in an old man Zhao Manhong who is not clear about the current situation. The old man is still living in the era of administrative distribution in the past, so it is naturally impossible to have any research on these current channels. It must be difficult to implement it. Besides, no matter how high the prestige of the old man is, it is only limited to this one-third of an acre of land in the Capital Military Region. And to implement the above-mentioned channels, only the relations within the capital military region can be leveled. That's really going to be used in all aspects of society. Such a relationship, in the barracks, it can be said that the old man Zhao, who has been "home" all his life, of course can't touch the door.

Of course, at this moment, the old man Zhao Manhong can only say that he has such a mind. His current attention is still on his "support" or "assistance" of the team at Tsinghua University to build this fully automatic machine gun. The old man has been dealing with firearms all his life, and this is the first time he has transformed a gun to the point that he can't start. Yes, all the places that could be touched by hand when used are now occupied by wires or wire spokes. That dense appearance, if you reach up at this time, it is certain to prick your hand. Of course, because of the spoke drive, it was not possible to touch it with your hands. This is because if you touch it, you may cause a combo and cause an accident. The old man knows this very well in his heart. It's just that just from this weapon, which has been quite changed from the gun and is still named "machine gun", the old man has a full sense of freshness. This freshness was the first time he had come to him after so many years in the barracks. Old man Zhao, who prides himself on being very familiar with the weapons of the army in active service, and can disassemble and reload the firearm with his eyes closed, does not dare to boast that he can also complete the disassembly and reassembly with his eyes closed when he and these little guys make up this new weapon this time. Because this is a weapon that I have never seen before.

The more this is the case, the stronger the old man's sense of expectation for this fully automatic machine gun after the completion is strong. He just wanted to see what this new machine gun, which he had never seen before, had never touched, or even thought of, would look like when it was truly fully assembled. When its power is really exerted, what kind of degree can it reach?

The old man put down the pliers in his hand, looked at the wires that had been scattered around and added to several large boxes, and was both excited and worried. I was excited because I saw that there was not much time left until the final answer was revealed, and my expectations would soon be answered. And the worry is because, looking at the scattered wires on the ground, the weapons I have seen before are all very compact, where can there be such a loose appearance? Can such a fully automatic machine gun really achieve its combat mission?

If the old man's worries were known to Liu Yihao and his friends, he would definitely comfort him immediately. Because in fact, the machine gun that everyone is currently working together is actually not the form that was finally submitted. Just as when developing airplanes, everyone had to build a test bench like the "Iron Bird" that could never fly on the ground for verification tests of lines and pipelines, and the "fully automatic machine gun" that everyone is currently manufacturing is actually just a "sample gun" for verification tests. After the tests to be conducted, if the test proves that the sample gun has fully achieved everyone's research goals, the next work is to integrate the scattered modules.

The friends are all from the Department of Electronics of Tsinghua University. Everyone knows that one of the characteristics of electronic products is integration. Generations of electronic and electrical equipment have a common feature, that is, the integration is getting higher and higher. From the first generation of electronic products to the thick, bulky, heavy and calorific tubes, to the second generation of electronic products replaced by those small and reliable transistors, to the third generation of products that only have capacitors, resistors and a few integrated circuit inserts on the circuit board, it can be said that the development of the entire electronic technology is developing in the direction of small integrated circuits. How could students who come out of such a major let the project design led by themselves end up in such a scattered and scattered structure? So the final integration will be that those extra wires will be shortened to the point that they are invisible, or even condensed into a solder joint. The modules that are now scattered will be consolidated into a single box. Because such a box is the initial form that the first generation of combat robots called "Terminator" should have.

Of course, Liu Yihao's planned miniaturization and integration goals, although they were also planned by Shen Yiyi, she was born as a mechanical engineer, and she also considered a problem that Liu Yihao had not yet considered. That's the heat dissipation problem. As the level of integration increases, components and modules that are now scattered end up being encapsulated in a confined space. At this time, there is a factor that cannot be ignored. Since junior high school physics, everyone has learned several properties of electric current, and one of the most easily overlooked is the thermal effect of electric current. Yes, all electrical and electronic appliances generate heat. It can be said that heat dissipation will always be a problem that all electronic and electrical components should consider when designing.

When I was in junior high school, I often only paid attention to calculating the relationship between voltage, current and resistance, and the textbook did not give any specific formulas or exercises for current heat generation, so everyone was not impressed by the thermal effect of electric current. The components of the middle school physics test are all exposed in the atmosphere, and those components that are very separated, under the action of the safe voltage, the thermal effect of the current is not a very significant problem. So the students were not impressed by this.

When Shen Yiyi was an engineer in his previous life, he had seen with his own eyes the damage of components caused by excessive current in specific engineering practice, and even the phenomenon of short circuit fire caused by excessive current. Therefore, she is very sensitive to the electric heating effect of all electrical equipment. In addition, all the electronic control elements will be integrated in the future of this machine gun, and the machine gun itself as a weapon, continuous firing of bullets will cause overheating of the barrel. In this case, the thermal heating will definitely cause the failure of the machine gun and even cause damage to the equipment. This problem may not be obvious at the time of the accumulation of data purely for the purpose of writing a thesis in the experimental stage, but it will not be possible to avoid it in the future when this prototype develops towards a weapon that can be used in practical applications. In other words, for the function of the entire equipment and for the reliability of the entire machine gun, the problem of heat dissipation is a problem that cannot be avoided and should be actively solved.

Shen Yiyi regretted it a little at this time, but he still thought about the problem at that time. At that time, I only thought about the mechanical and electrical parts of the whole project, but I forgot about the thermal analysis. When he was engaged in the engine in Shenyang, Shen Yiyi still carried out thermodynamic heat transfer calculations. However, when this project was first planned, I didn't think about the need for heat transfer analysis. Therefore, this part of the work was not planned in the previous design and calculation. Now when the prototype is about to succeed, I remember that there is still such a piece missing. It seems that I still have to hurry up and think of a way to make up for this piece as soon as possible. Otherwise, this "terminator" of oneself will only serve his thesis in the end, but it will not be transformed into the combat effectiveness of our people's army, and it will not become the productive force of himself and his classmates, which is not the result that he wants to accept.

Of course, at the prototype stage, the current machine gun in this form still does not need much heat dissipation. With just a few scattered modules of this size, their heat dissipation area is enough to dissipate the electrical heat generated now. At this stage, the focus is still on the verification of the principle of the functional sample gun as soon as possible. (To be continued.) )
