"The harvest during this period is really great. Let's not talk about finite element analysis. It is a set of applied mathematical algorithms that are comparable to the world. Unexpectedly, I also learned the manufacturing methods of epoxy resin and fiberglass, which are any military technology.

The lightweight material that people dream of!”

Zhang Yi sat at the desk in the dormitory, holding the notebook he carried with him. While looking at the densely recorded words and symbols on it, he kept expressing his emotions. The unfinished look in his eyes seemed to be like this moment.

He was still at the development site, listening to Bai Yi's profound yet humorous explanation.

So much so that he was still intoxicated until now. He only felt that this midnight was extremely wonderful. The nerves in his brain were so wonderful that they were beyond the constraints of the biological clock and kept running. So, he put down the notebook in his hand and excitedly

I walked around the room twice, muttering as I walked: "Let me tell you, Captain Bai has set the total combat weight of the No. 1 recoilless artillery at 18 kilograms, and the total combat weight of the No. 2 recoilless artillery.

Set it to about 7 kg.

Now it seems that he has already calculated. No, as soon as fiberglass comes out, some of the original steel parts can be replaced. You must know that fiberglass is a durable material that is lighter than aluminum alloy. Once it is applied to our recoilless artillery

, then the total combat weight will inevitably plummet..."

As he spoke, Zhang Yi's eyes were a little confused, but more of reverence. He stared at the curtain-like dark night outside the window, as if he had seen the scenes of Bai Yi leading the development of recoilless artillery during these days.

After solving the production and processing of epoxy resin fiberglass, Bai Yi finally proposed two recoilless artillery plans with different shapes.

In Bai Yi's words, using the principle of a recoilless artillery, two types of infantry support equipment at the battalion, company level and squad platoon level can be completely developed, namely the so-called No. 1 recoilless artillery and the No. 2 recoilless artillery.

The structure is similar, but there are differences in caliber.

The No. 1 recoilless artillery adopts an 80mm caliber and fires traditional recoilless artillery shells. In order to make the shells fly more smoothly and have a longer range, the No. 1 recoilless artillery changed the smoothbore structure of the American M18 57mm recoilless artillery.

, adopting a rifled structure with prefabricated rifling of the gun barrel.

As a result, the fired shells are like bullets. With the help of the rifling, they fly to the target quickly and steadily. Of course, because of this, the bore of the No. 1 recoilless artillery is made of high-strength steel. If it were not made of fiberglass

It appears that no matter how much weight is controlled for this type of large-caliber recoilless artillery, the barrel will be made quite thick due to rifling and structural problems.

But now with fiberglass, the built-in steel inner chamber can be made as thin as possible, and the outer layer can be wrapped with fiberglass. This not only achieves a stable structure, but also greatly reduces the weight of the main gun, so that it can be used with only one or two soldiers.

The purpose of easy operation.

The same goes for the No. 2 recoilless artillery. The difference is that the caliber has been reduced, set at 40mm, and the ammunition uses a rocket fuel booster structure. This allows the use of super-caliber ammunition with a larger caliber than the original. The structure is also more precise.

It is simple, a seamless steel pipe, and the tail is supported by reinforced fiberglass like the No. 1 gun, thus becoming a powerful direct-fire weapon that can be used by individual soldiers.

To be honest, if Zhang Yi had heard these words before, although he could not say that he would have sneered at them, he would have thought that all of them were fantasy. But after he saw finite element analysis and epoxy resin fiberglass, he no longer felt that

Those unattainable indicators are so out of reach.

The built-in steel barrel of the No. 1 recoilless rifle had to be made as thin as possible and rifled at the same time. Before today, it might have been very difficult because it involved a lot of testing, calculations, and repeated research and verification.

After all, it is necessary to find out the maximum bearing capacity of the material of the built-in steel barrel as much as possible, and then use this bearing capacity to find the best thickness balance point.

But now with finite element analysis, just by testing a few basic data, you can easily calculate the potential boundaries of many materials, including the maximum bearing capacity of the steel barrel, so that you can quickly determine the thickness of the built-in barrel.

The same is true for the externally wound fiberglass. In this way, the development time of the two equipments can be greatly shortened, and the related costs will also be greatly reduced.

If we also include the new technologies and new materials produced by the development of these two new recoilless artillery, it will have an extremely far-reaching impact on the entire country, because it has gone beyond the scope of one or several weapons, and has become a driving force for

The progress of the country's overall industry may even provide a good opportunity for direct overtaking.

This is the ultimate ambition of Zhang Yi, who has grown from an apprentice to a technical backbone step by step. Because of this, he eagerly studied the various technical knowledge described by Bai Yi to the point of being intoxicated; because of this,

He admired Bai Yi who promoted the application of new technologies, and felt that he was extremely lucky and extremely happy to be able to join this research and development team.

However, just when Zhang Yi looked away from the night outside the window with a happy and confused smile, and turned back to his desk, Feng Chong's dazed face made Zhang Yi's happy expression even more intense.

Then he quickly walked over and patted this good friend on the shoulder: "What have you been doing these days?"

What’s wrong? You always seem to be distracted? You’re still worried about the exposure of the report letter, right? But I think, since you have gone to recover the letter, it doesn’t matter even if Team Leader Kashiwa finds out, after all, Team Kashiwa

I still have a broad mind, so I won’t make things difficult for you because of this.”

"I……"

Feng Chong listened to Zhang Yi's advice and wanted to explain something, but before the words came to his lips, he swallowed them back. What could he say? Just half a month ago, Bai Yi used practical methods to explain.

His skills proved that he was a well-deserved authority in this group. Not to mention leading the backbones like them, he was more than enough to become their mentor. Faced with this fact, Feng Chong only felt that Lian Biren could slap him a hundred times.

There is also burning pain.

He regretted that he should not have spoken out against Bai Yi, and that he should not have written the report letter impulsively. So under Zhang Yi's persuasion, he went to the Northeast Bureau the next day to try to send the letter to him.

After trying to recover it, what was counterproductive was that the report letter had already been taken over by the relevant departments and it was impossible to recover it. Feng Chong was very frightened.

There was even some suspicion for a while, fearing that the matter would be exposed. With Bai Yi's prestige, Feng Chong would instantly become a public enemy of the entire development team. Whenever he thought about this, Feng Chong would feel uneasy, so much so that his whole body

He lost weight several times, but as time went by, Bai Yi did not receive any questioning from his superiors, and Feng Chong did not receive any pressure from Bai Yi. In this way, Feng Chong breathed a sigh of relief and felt that this matter was over.

.

So he kept this moment in his heart, hoping that it would be completely destroyed, but he didn't expect that for some reason today, this very shameful secret in his heart suddenly grew fiercely, making Feng Chong unable to control it no matter what.

As for his face that looked very ugly at the moment, fortunately the lights in the room were dim, so it wasn't too light to look at. Otherwise, Zhang Yi might have seen the clues.

However, regardless of whether Zhang Yi could see it or not, Feng Chong made up his mind at this moment to tell this good brother in front of him because he couldn't resist anymore, so he raised his eyes and was about to speak, but...

I heard an angry scream from a young girl outside the dormitory door: "Damn it, whose report letter was it? It's fine now. Team Leader Bai will be transferred out of the military industry system tomorrow. Now you're satisfied... Wuwuwu...
