Chapter 324: Seven steps away, the gun is fast
This is the main purpose of this time. The spear stab is an unexpected gain, and it is not something too important.
Hey, it’s pretty fast. Gao Zhendong quickly picked it up.
After opening it and looking at it carefully, I realized why it was so fast. To put it simply, this is not a complete team weapon design result, but something similar to a rough design and preliminary design in the first stage.
It does not involve the internal structure, mechanical connection, or specific automatic process of the firearm, but rather focuses on indicators, requirements, and technical routes.
For example, the automatic principle is only designed to use a short-stroke piston gas-guided automatic with a gas regulator; the locking method is only designed to use a bolt rotary lock, etc., and the others are basically the same.
As for how short the specific piston stroke is and how to lock the bolt rotation, there is not much involved.
The entire design is still in the middle stage from top to bottom, from thick to thin.
As for the spear stab seen earlier, it is an exception. After all, the thing is really simple, and the steel is available, so it may be drawn by hand.
Gao Zhendong looked at it carefully. Since he has not yet entered into the specific design, there are many details that he does not need to look at. However, when it comes to mechanical things, Gao Zhendong is not as clear as someone with a professional background.
So what he is best at is probably at this stage.
Looking at the concept drawings of firearms, since it is a gun-oriented design, many problems of assault rifles and light machine guns are common.
Gao Zhendong pointed at the concept map and spoke his thoughts bit by bit.
The problem that can be seen at a glance is that the assault rifle seems to be missing something.
There is a folding straight support, but the place where the straight support is connected is the same as that of the previous "nib-bang". The handguard has a downward curvature from the end of the receiver, and then folds Trust is connected to this.
From the looks of it, there should be a steel structure inside and a guardrail covering the outside, otherwise the strength would be unbearable.
To put it figuratively, it is like there is half a small grip at the end of the gun, and then the support is directly connected to the half small grip.
Looking at this design, Gao Zhendong’s face twitched a little.
It seems that he still hasn’t gotten out of the rut of “nibbling and punching in one”. Gao Zhendong smiled and tapped the place behind the trigger guard.
“Here, I suggest adding a small grip, so that it will be much more comfortable to hold the gun when shooting, which will help improve shooting stability.”
Several students listened and whispered to each other.
“I just said to add a small grip, just like the previous generation, but you don’t.”
“This small grip is good for bayonet fighting. Besides, this kind of In the form of stabbing and holding, you can still pull the trigger and shoot. Isn’t that killing two birds with one stone?”
Everyone was discussing in a low voice, but Professor Liu somewhat understood that the person in front of him was interested in this. He is much more interested in dumping bullets than playing with bayonets. Although he likes to play with bayonets, if he really needs to use them, he is more willing to use bullets.
He opened his mouth and summarized everyone's thoughts: "That's it, Director Gao, this design mainly takes into account the need for bayonets, so."
Gao Zhendong didn't say not to fight with the bayonet: "You can try it out. The straight support is designed properly and the grip feels good. It will not affect the bayonet fight. The point where the back hand exerts force when fighting the bayonet can be supported by the tiger's mouth. Use the protruding part at the rear of the receiver to apply force, and then make a little plastic wrap around the straight part of the folding support. The thickness is suitable, and the effect is not bad.”
It is also difficult for Gao Zhendong. In order to reverse this awkward design, he even brought out things that were not on the "transitional-to-normal" gun in his previous life.
On that gun, apart from the longitudinal reinforcement grooves, there are no gripping ridges on the straight stock part.
Looking at the schematic diagram Gao Zhendong drew on another piece of paper, Professor Liu thought for a moment, and even held it virtually with his hands, made a few gestures, and then nodded: "Well, Director Gao, this The suggestion seems to work, let’s go back and give it a try.”
Gao Zhendong added: “And in this way, the connection point of the gun stock will be moved upward, basically on the same axis as the barrel. This is good for suppressing jumping up during recoil.”
He knows what everyone dislikes the most about the previous generation, and it’s just jumping on the bandwagon. Come on, I’ll use this advantage to add another handful of dirt to the grave of this design.
Everyone nodded slowly along with his narration. Director Gao's words indeed made sense.
"Director Gao, what about the advantage of being able to shoot at any time? Is it something that can be discarded in this design?" This classmate did not mean to argue at all. He just wanted to learn more. If you have questions, ask them. How to choose is also something to learn.
Gao Zhendong laughed loudly: "Classmate, believe me, as long as there are bullets, we generally won't think of fighting with bayonets. Moreover, even with a small grip, it is still not difficult to shoot quickly. , our soldiers can make up for this with training. "
Hey, if you want to fight with a bayonet, then I will use hard training to make up for it. Both of these are irrefutable slides. .
In fact, we used to fight hand-to-hand at every turn, most of which were forced out by lack of ammunition. During the Anti-Japanese War, a soldier could only have a few bullets and a few grenades in a battle. These few grenades might explode in half. , can only be used as a side zone of the atmosphere group. There is a very old novel called "Qinghe Qianqiang", which has a relatively detailed description of the hardships at that time.
So the subsequent explosion in the production capacity of bullets and grenades may also have a bit of a retaliatory consumer psychology out of fear of poverty.
Gao Zhendong explained the reason: "We may put the enemy at a distance of 10 meters or even 5 meters to fight, but even at this distance, as long as there are bullets, hand-to-hand combat is still not the first choice. Classmate, Design Remember this when handling firearms."
Having said this, he paused, and then cleared his throat in the eyes of everyone who was full of curiosity.
"A gun is fast at seven steps, but within seven steps, the gun is accurate and fast!!"
Professor Liu, who was so shaken by his baggage that he almost laughed out loud, jotted down this sentence, I didn't expect Director Gao, who was nicknamed "Big Cannon", to be so interesting.
Amidst everyone's laughter, Gao Zhendong also smiled and clicked on the drawing: "What shape of parts are we going to use for this place?"
The place he clicked was for the piston. Retreat range of motion.
Here is a round tube on the AK-47, and the piston reciprocates in this round tube.
Professor Liu took a closer look and replied: "Initially, we are considering round tubes."
We have not yet entered into a comprehensive detailed design. The initial consideration here is to be consistent with AK-47 and imitation models.
Gao Zhendong shook his head: "Just replace the curved cover, which can cover the sand and prevent it from getting in."
A classmate asked: "Director Gao, we think the previous generation was a round tube. , they are all fully automatic, that one works well.”
Gao Zhendong almost laughed out loud, you mean fully automatic, just use the round tube of the AK-47, semi-automatic. SKS’s curved cover, right?
He made several gestures with a pen on the concept map: "Think about it carefully?"
It is also a good thing to let them use their own brains. When Professor Liu listened to Gao Zhendong's talk about changing the curved cover, He started thinking and laughed at this time: "Director Gao is smart, use an arc cover!"
Seeing the students looking at him, he waved his hand: "Think to yourself, today I will be Director Gao and I’m teaching you, haha.”
These students are not fools. How can there be any fools who can be brought here by Professor Liu?
Soon, they were discussing it all.
"I understand, there is no need to use round tubes here! It can save materials. Originally, the long-stroke piston of the AK-47 had a tendency to lower its center of gravity because it was too forward. The bolt frame restraint alone was not enough. There must be a full The enveloping circular tube constrains its front end so that it can move freely according to the designed motion trajectory. However, the center of gravity of the short piston is rearward, so this constraint is not needed at all. It is enough to constrain the rear half of the piston with the bolt frame! ”
A classmate quickly understood.
With him in front, other students also expressed their opinions.
“Yes, yes, you are right, and the benefits are not limited to this. In this way, the distance between the piston and the arc-shaped cover is increased, and the tolerance to debris is also improved. A lot.
“Well, this part is also easier to handle when the soldiers clean the gun. The tube is definitely not as easy to clean as the curved cover. ”
Seeing everyone speaking enthusiastically, Professor Liu was also very happy: "What else? There is another biggest benefit that you haven't mentioned yet."
After saying that, he, like Gao Zhendong, also drew on the concept map I made a few gestures and the movements were roughly the same.
Watching the same action again, a classmate suddenly realized: "The center of gravity is still the center of gravity! Without the lower part of the round tube, the piston can be designed lower and the center of gravity closer to the barrel axis. In this way The impact of the movement of the piston on the stability of the firearm is minimized! What Director Gao wants to focus on is the accuracy of the gun!"
Professor Liu laughed, this was an enlightenment.
"Yes, what Director Gao has always wanted to do is to improve the accuracy of the firearm within the shooting range without reducing other performance! The purpose of adding a small grip is to move the gun up The purpose of setting up the connection point is also for this, and the way to change the piston shielding constraint is also for this, but while achieving this main goal, he also did not forget to take into account some other benefits! It’s what you need to learn more from.”
Gao Zhendong looked confused. Actually, I'm not as good as you said. I'm just copying what I saw in my previous life.
No matter what he thinks in his heart, the students believe what Professor Liu said anyway. It doesn’t matter what you think. Anyway, this is what you show.
Seeing that they believed in him so much, Gao Zhendong was not polite. In that case, I would like to ask you to resolve a little regret about the gun in the previous life.
You're welcome, this is what I should do.
