Chapter 425: What’s next?
At this time, several people have already arrived at the testing site. Since they have decided to do it, they can first communicate with the students and do some preliminary work.
A few people told the key staff Gao Zhendong’s idea. Everyone looked happy and seemed to be able to do it.
A student thought for a long time and asked a question. This should be a more active one. While the teachers are all around, ask questions quickly.
"Teacher Gao, the anti-jump ring you mentioned seems not easy to arrange."
Since he is a school teacher, there is nothing wrong with this title.
Gao Zhendong thought for a while and drew a picture: "For example, this is just an idea. You can explore it for yourself. It doesn't have to be the same as it, killing pigs and butts, everyone. There are various killing methods, the main one is to achieve a jump explosion. As long as it is suitable, you can put some explosives into the fuse, but in that case, the fuse will appear larger, as long as you can balance it. "
< br>As for whether this ring is a wind deflection ring, an anti-jump ring, or an auxiliary device to increase the firing rate at a small angle, Gao Zhendong has never seen the sections and drawings of these bombs, so he can only guess. However, he has seen all the types of ammunition of this rocket launcher, and only this air-explosion grenade has this ring, which seems to explain a certain problem.
The idea is given to you, you can feel free to use it how you want to realize it.
Professor Luo looked at his students: "You still haven't grasped the core of what Teacher Gao said. The core is jump explosion! Jump explosion!"
The student touched his head and smiled.
Professor Liu’s students also gathered around and asked Professor Liu: “Teacher, I have a question. This front-loading grenade relies on prefabricated grooves and rifling to achieve cooperation. In this way, the insertion of the bullet is very difficult. There are requirements for the posture, which is not easy to deal with. "
Gao Zhendong shook his head: "You have many choices. "This is not copying anything. There are many ways to go."
Once students are entertained, do they still have many choices?
“First of all, you can retain the warhead of the bullet, and then design the high and low pressure charging parts into the bullet case to make a new bullet, and then you can design it according to the traditional automatic method. Just in this way, The universality of ammunition is compromised.”
Others think this is a solution, but it is a final solution, mainly due to financial and procedural issues.
"Secondly, let's use the already designed bullets and decide on the launcher. Those of you who are engaged in firearms should know about revolvers, right? Let's enlarge the revolver a little and treat it as a gun. Six gun-mounted grenade launchers are tied together, so that a six-shot automatic launcher can be produced."
"Even from the characteristics of this grenade, as long as the rotating grenade nest is also the launch tube, Even the barrel can be omitted. It couldn't be simpler. Grenade machine gun. You can't really limit your thinking to the 'machine gun'. The core of this thing is automatic grenade launch."
When everyone thinks about it, this is really what happened. If someone who deals with firearms says they don’t know about revolvers, that would be very disrespectful. However, this is not necessarily the case, and they don’t know about the famous gun of kindness later—— How did the police wheel come about?
This method is very simple to implement, but when it comes to the front-loaded grenade, the current rear-loaded revolver structure cannot be used. Instead, it needs to be retrograde to the oldest front-loaded revolver structure.
A student asked Gao Zhendong: "Teacher Gao, this method is good, but the firepower sustainability of 6 rounds is not very good? Can you install more?"
Gao Zhendong shook his head: "Turn around." The wheel structure, in theory, has the best balance between space utilization and firepower sustainability, which is 6 rounds, 6 rounds around the middle axis, because the bullets of the runner are all in the outermost circle, so the more bullets are loaded, the better the space utilization. Bad.”
If nothing else, take the AA-12 fully automatic shotgun, which will be very famous in the future but no one cares about it. The drum drum is a typical waste snack, and the bullets are surrounded on the outside. Ring, it's big and heavy and can't hold many bullets.
"But you don't have to worry. In fact, the firepower of this thing with 6 rounds of continuous fire is almost enough. If you don't believe me, ask your comrades in the army."
It will be installed in the country in the future. The grenade launcher has a small ammunition capacity, so it can't be used to supply larger ammunition? That's definitely not the case. Counterfeit MK-19, AGS-30 and the like are sold everywhere. The reason why I don't use them is that they do not meet our usage requirements.
——It’s inconvenient to carry it around.
Our habit is to wander around even when fighting positional battles.
The thought of positional warfare: a crazy rush at a point until the end.
Actual positional warfare: A combat group controls multiple positions, fighting here for a while and there for a while.
Even in actual combat, it is not uncommon for a person to prepare weapons in advance on multiple preset positions, fight here, fight there, and resist the enemy for half a day and a day.
Sure enough, the student turned his attention to the troop representative, who smiled and said: "Chief Engineer Gao is right, 6 rounds are almost enough. Of course, a bigger one would be better, as long as it's not too heavy, hahaha."
We worked hard to make the 12.7 high-altitude aircraft weigh 26kg. In addition to being deceived, it is also because of the most straightforward pursuit of firepower and mobility.
Professor Liu smiled and said: "Is there any choice?" Gao Zhendong said with a smile: "You are engaged in firearms, so you should be more familiar with mechanical automatics than me. However, I have some superficial suggestions, which may not necessarily be correct. . ”
This made Professor Liu and the others blush a little, but then they thought, this is a teacher from their own school, so it’s okay.
"If you want to make it bigger, you will undoubtedly have to use a bullet chain to feed the ammunition. Compared with the uncertainty of the posture of the bullet, when the bullet chain enters the automatic mechanism, its direction is relatively fixed, right? You are here for the grenade In addition to the pre-rifled slot, there is also a positioning slot in the launcher, right?”
Everyone nodded, that’s right.
There is no need for Gao Zhendong to continue, Professor Liu has already finished his thinking: "What Chief Engineer Gao means is to make a structure such as a positioning protrusion on each bullet link, and fix the grenade in advance. The positioning of the protruding docking automatic machine and the guide device inside the gun barrel at the same time to achieve the position of the grenade into the chamber?”
Professor Liu, you can answer everything I want to say. That's it.
Gao Zhendong nodded: "With this method, the shape of the bullet may need to be modified. For example, in order to ensure the reliability of guiding the positioning groove, a wide-mouth guide groove should be made in front of the positioning groove. At the same time, We should pay attention to issues such as the coordination of the negative lines of these grooves and rifling grooves, but the changes will not be too big, and the possibility of implementation is quite high. ”
Another small problem is that it is a little harder for the comrades to load the bullet. When loading the bullet, the bullet must be pointed at the gun first.
Everyone thinks this is a good idea. If you want to be lighter, bring fewer rounds of ammunition and put them in a chain magazine like Lao Maozi's RPD. If you want to have good firepower sustainability, then use a big chain box. .
And we are not afraid of not being able to achieve results. There is a runner structure as a guarantee, which is basically stable. The runner structure plan is too simple in structure and does not cost a lot of money. What if the bullet chain fails? Even if you don't come out, you can guarantee that there will be practical results if you are there.
The army representatives and Professor Liu happily wrote down Gao Zhendong's words and took a look. It would be beneficial to ask more questions. Now, the technical part of the project application materials is half completed, and they also have a plan comparison. Chosen.
Actually, Gao Zhendong didn’t want to say so much originally. It would be best to let the researchers figure out their own solutions. This thing is not a high-tech product and there are major technical barriers. What he said, these guys Those who engage in firearms can think about it if they think about it more.
But even after asking questions, it’s okay not to say a few words, otherwise it will still have a big impact on Gao Zhendong himself.
This afternoon, Gao Zhendong's half-day class turned into a whole day, but overall it was worth it. The cannons in the hands of the infantry are still very important.
At about the same time, at Haihekou 1761 Institute, Yu Yuncheng looked at the test data brought over by the experimenters and made a decisive decision.
“Well, it’s almost done this time, let’s go to the capital!”
——
In Gao Zhendong's office, Gao Zhendong looked through the test data he brought, and Yu Yuncheng explained to him while drinking tea.
"General Engineer Gao, now it seems that the process time optimization you mentioned is still very possible. Judging from the encryption sampling results, the changes in the crystal structure are the most dramatic in the first 48 hours of annealing. , and then it starts to gradually level off, that is to say, we don’t need to complete the original annealing time of 45 days. Judging from the crystal structure requirements you gave, my suggestion is that 10 days is enough. "
Gao Zhendong nodded: "Well, yes, not strictly speaking, 3 to 5 days is fine, but from a safe point of view, the 10-day suggestion you put forward is better. , Don’t worry about being late for a good meal.”
Yu Yuncheng smiled: “Finally, it lives up to your expectations. This thing has been built. I have calculated that the overall crystal utilization rate is very high, and the structural yield rate is very high. It's also very good, but this crystal is a bit small."
Gao Zhendong smiled and said: "Don't look at it, but it is very useful. So, did you bring a qualified finished crystal this time? ”
Speaking of this, Yu Yuncheng didn't feel sleepy anymore: "In addition to leaving the necessary test samples, I have brought you all the qualified ones this time. It's not too much, but the quantity is not too small either. I'm afraid that on the road If there is a problem, a comrade from the army will be assigned to escort him.”
Gao Zhendong was overjoyed: “Okay, great. Now you can go back and finish the finishing work and prepare for the acceptance of the project.”
Yu Yuncheng nodded: "Okay, by the way, Chief Engineer Gao, after this time, are there any other issues?"
Gao Zhendong thought for a while, there is nothing urgent for the time being, but it can still be done Give him some direction.
“I don’t have any here yet, but I have a suggestion.”
"Say." Yu Yuncheng was very interested. The direction Gao Zhendong mentioned here must be unique.
“You can consider doing CVD, whether it is to open up new roads or improve the original technology.”
CVD (Chemical Vapor Deposition) at this time, belongs to the pre-dawn period In this dark period, it is still very useful to do something about it.
