The next day, the team of Lorraine Agriculture and Forestry Machinery Factory once again challenged the wading off-road and successfully got back up where they fell...... Everyone was excited, and then won several other events arranged on the day in one go, two of which set a new record in the first round. In this way, even if they don't challenge for extra points, they bite the other teams tightly and stay in the first echelon of the championship competition.

In the evening, all the engineers and technicians of the participating teams had a meal, and although they only drank a small amount of alcohol, the atmosphere was very warm. Weiss's "trick" worked, and everyone greeted him, and among them, only the newcomer Zoson Rignauert seemed to be not so excited.

After the meal and wine are full, the diners gradually disperse, those who should be busy continue to work, and those who should rest sleep with their heads covered. Weiss came to Zuosen: "Let's talk? ”

Zuo Sen has been joining this team for some time, and he knows what kind of role Weiss is, so he nodded: "Okay!" ”

The two walked out of the tent of the dinner party, side by side for some distance, Weiss stopped, turned around, and said in a low voice: "Hohenstaufen IV is bullshit!" Hohenstaufen IV is stinky bullshit! ”

"Huh?" Zuo Sen looked at Weiss in surprise, behind that layer of surprise was a layer of confusion, and in the confusion, there were clearly three points of horror and seven points of anger.

Weiss took the other party's micro-expression into his eyes and knew it in his heart. He smiled slightly, with contempt in his smile: "I am also an old acquaintance with Prince Barras, and I have dealt with each other several times, and it is positive. I think there is both mutual admiration and disgust between me and him, just like the competitors in this arena...... It would be nice if one day we would no longer be hostile to each other, no longer be on guard at all times, and sincerely become friends, drink and talk, and only talk about the wind and the moon! ”

Zuo Sen opened his mouth, and the words that were covered up clearly reached his mouth, but he swallowed it back. He sighed: "What a pity! I wanted to get along with everyone for a while, but I was happy to stay here despite my position. It must be admitted that the people of Lorraine are full of enthusiasm for life and sincere in their friends...... What a place, what a company! ”

Seeing that he still did not show hostility, Weiss was even more convinced of one of his conjectures, so he slowed down his tone: "You should feel glad that now our two countries are working hard to promote the normalization of diplomatic relations, and you are here, and you have nothing to do with military secrets, so you will not be charged with spying on military intelligence, and presumably your identity is not in question in terms of legality, so ...... We can have a good chat in peace. ”

Zuo Sen responded unhurriedly: "You should know that there are some things that I protect with my life, oaths, honors, and other things, so ...... You don't have to bother searching for confidential information from me. ”

Weiss said calmly: "Today, we only talk about technology, how about it?" ”

Zuo Sen's hands were changed from naturally drooping to hugging in front of him, a posture that significantly reduced aggression, but his eyes were still full of vigilance, and his attention was also in a state of high concentration. Feeling that there is a stir around him, he will run away, and maybe he will also carry a guy to protect himself or cut himself.

Weiss stretched out his hands: "What do you think about the torsion bar construction?" What I want to hear is what you really think! ”

Zuo Sen pondered for a moment and replied: "The torsion bar structure is a deformation of the spring principle, and the elastic force is obtained through the torsional movement of the metal structure. Generally speaking, the load wheel is connected to the torsion bar through the toggle joint, and when the load wheel moves up and down, the toggle converts the movement into the movement of the torsion bar, and the elastic force of the torsion bar produces a cushioning force. Compared with our common vertical springs, the torsion bar structure is more elastic, and the torsion does not require additional space, and the structure is clear, stronger and more reliable. What are the disadvantages...... Once damaged, it is much more troublesome to replace than a spring. ”

As a future engineering man and military enthusiast, Weiss knew he was talking about both the real and the dry. The operating principle of torsion bar suspension is simply to install one side of the torsion bar on the side wall of the car body, and the other side is penetrated through the hole of the car body and connected to the swing arm, and the weight load on the wheel makes the torsion bar twist through the swing arm, and the elastic force obtained is used to support the car body. The advantage is that when the vehicle is off-road, the load wheel will only let the torsion bar rotate with the shaft of the car body as the center of the circle, reduce the mechanical loss, and its dynamic stroke is large, and there is no other suspension that needs to consider the length of the spring. The disadvantage is that the bottom of the vehicle is occupied by the torsion bar, and a large part of the space is squeezed, so that the height of the vehicle is bound to be squeezed by the torsion bar to occupy a part of the space, and there is no compromise, and once the torsion bar is damaged, its repair is not a simple battlefield can be completed, and generally must be sent to a large repair station in the rear. In addition, in a torsion bar suspension system, the diameter of the load wheel must not be greater than the distance between two adjacent torque bars, which limits the size of the load wheel. In the battle, the large diameter load wheel has some advantages, such as good off-road performance, small vibration at the moment of parking, in this case, both the load bearing and the vibration at the moment of parking should be considered, then the staggered load wheel is a natural choice.

"When the total weight of the vehicle does not exceed a certain level, the torsion bar structure is selected, as long as the material is passed, the advantages can outweigh the disadvantages, but there is a limit value in the material performance, close to this limit value, it is no longer possible to improve the elastic force and bearing force through the improvement of the material. According to my estimates, the approximate upper limit of this total weight is 8 to 100,000 pounds, what do you think? Weiss deliberately steered the conversation into seemingly purely technical territory, and even took the initiative to reveal some important information. As a master in this field, it is not difficult for Zuo Sen to distinguish the authenticity, his brows furrowed and loosened, loose and wrinkled, hesitated for a while, and then looked around, and saw that there was no abnormality, and then said: "I personally agree with your inference, under the existing technical conditions, it is impossible for us to build a very large vehicle with a tracked structure, even if we do not consider the bridge and road load-bearing, we must weigh the width of the air and railway vehicles." ”

This is only said about the first half, because the latter half is easily associated with the military: only when armor and firepower are taken into account, the overall weight requirement of the tracked vehicle will exceed that upper limit, and carrying wood or agricultural products, the center of gravity has been overweight before, and even normal movement cannot be guaranteed, what kind of structure?

"Under the condition that the length remains the same, the torsion bar increases to a certain diameter, and the elastic force should be able to break through the upper limit, but the bearing force of the overall structure, especially the load-bearing part, is estimated to have a big problem, at least in the current design of single-row load-bearing wheels, the problem cannot be solved." The reason why Weiss emphasized the "single row of load wheels" was to deliberately lead the topic to the staggered load wheels. Judging from the historical "precedent", although this is a feasible way to solve the problem temporarily, it has both advantages and disadvantages, and once it goes to the extreme, it will cause a "catastrophic drag".

Zuosen didn't answer immediately, and judging by the apprehension in his eyes, the Normans had realized the feasibility of the staggered load wheel design. From the perspective of engineers, if the opponent also "enlightens" and follows up in time, the wisdom they have contributed before will be diluted a lot.

Weiss was not in a hurry to speak, and waited quietly for him to speak. After a while, Zuo Sen said vaguely: "On the battlefield, technology is only one aspect that affects victory or defeat, and the key is to look at people." ”

"Tactics are better than technology, huh...... This is your consistent understanding, and it is also your sharpest invisible sword. Weiss said thoughtfully, "Looking at the last battlefield, I think the weapon that had the most potential to change the tide of the battle but unfortunately missed the opportunity was none other than the Wessex assault ship." If they had played their intended role, perhaps the Confederation would not have been hit so hard. Well, it's far away, the real tactical power of the assault ship is great, so on the ground, is it possible to try an assault tank? Putting protection and tactics first, firepower and speed second, is it still tactics to win? ”

Zuo Sen had no expression, his eyes were also confused, he didn't understand why the other party wanted to tell him this after he knew his identity? Could it be that the magistrate of Lorraine also admired hereditary status and power, so he made overtures to the royal family, and even used this to express his sincerity? So why do you say such disrespectful words as "Hohenstaufen IV is bullshit" in the first place? Or is he not going to let himself go at all today, and is just talking about himself right now?

Thinking of the last possibility, Zuo Sen couldn't help but gasp, his eyes narrowed, and a murderous aura finally rose on his body.

At this moment, Weiss also squinted his eyes, he saw the hostility of the other party, and also knew that his question had hit the "key point" of the other party step by step, which aroused the strong vigilance of the other party. In terms of force, the one in front of him is just a piece of cake for him, even if he doesn't use a cane, it is also the rhythm of lying down in minutes. Weighing the situation, he did not choose to strike first, but continued: "I have a very good friend who is also a top figure in mechanics, and I was reminded before that we have taken such pains to study ground vehicles, whether they are civilian or military, after all, they are operating on the ground. If the technical research of artificial star source stones is further successful, the number of flying ships will break through the original constraints, and in addition to military use, industry, agriculture, and forestry fields will be able to greatly benefit, and a large part of these vehicles that we are working hard to develop will lose their value. I reflected for a long time and felt that this was indeed possible, so I was confused for a while and wondered if there was any need to continue on this path. I'm curious, did you have any doubts about this before you came? ”

Zuo Sen said with a calm face: "Yes, but it doesn't matter. If that happens, I can switch careers to the aviation department and continue working mechanically, which is essentially the same. ”

"No, I think there's a difference in nature." Weiss argued, "Although they have a certain degree of commonality in terms of mechanics, I think they are two completely different paths, two systems, two dreams. I like to keep my feet on the ground and don't like to float in the air so much, while my friend is the opposite, he likes to fly in the air and doesn't like to move slowly on the ground very much. ”

"I'm just an engineer......," Zuo Sen said with some resistance, "No matter what you think, I don't know and am not interested in matters other than machinery, I stand here, there are a lot of accidents in it, if it weren't for you to see through, I might have stayed in Lorraine for a long time, creating some economic benefits for Lorraine Agriculture and Forestry Machinery Factory, it should be like this." ”

Weiss stared into his eyes and took in his micro-expressions, which, despite the high degree of validity of his words, did not mean that he was a "harmless observer". His ability and his positioning can certainly bring benefits to the Lorraine Agriculture and Forestry Machinery Factory, but for the Federation, it is a time bomb that "explodes" at some point, and once the confidential information is leaked, the damage caused can far outweigh the economic benefits.

After pondering for a long time, Weiss squeezed a sentence out of his lips: "You guys are such a horrible bunch! ”

In the Federation, how many lurkers like Zuo Sen are there? They may be distributed in all walks of life, although at the beginning of the person is soft-spoken, the level of contact is also low, and there is no threat, but through their own efforts and the accumulation of time step by step, the level and potential threat will increase day by day, and what is more terrible is that the longer these people are incubated, the more difficult it is to be recognized by the disguise of identity. Zuo Sen's identity for himself was to grow up in the eastern part of the Federation, and Brooks happened to be transferred to the east, Weiss asked him to help investigate, and professionals came out, but he couldn't find out the obvious flaws - unless he was sure that he had a problem, or used "fishing", hypnosis, interrogation, etc., or spent more manpower and material resources to dig deep into the details, and compare and verify through different clues, it is possible to identify this carefully arranged fake identity in this era of insufficient information technology.

When it was time to say what was said and what was supposed to be asked, Weiss caught a glimpse of several engineers nearby and deliberately shouted: "Catch him!" ”

Weiss's identity and experience, passers-by know, Zuo Sen has always been ready to go, seeing that the situation is not good, how dare he attack head-on, and run away. Although the engineers were at the intersection and could easily block his way, they didn't react at once, allowing the guy to slip over like a loach and disappear into the night.
