Chapter 325: The gun cannot be without grenades
He pointed at the receiver cover. It was not that he had any objections to the shaking receiver cover. Different from his previous life, this time he was concerned about it. I have no problem with the stuff at all.
This thing is just a dust cover. In fact, it can be used even if it is removed. The dissatisfaction in the previous life came from the difficulty of attaching accessories to this thing, but now I am very poor. Where can I get so many accessories? As for the installation, it would be nice if the gun itself could be finished.
What should I do if I have money and want to install accessories?
Believe in the wisdom of future generations!
It’s not out of the question to get a new one by then. It will happen decades later. It can be said to be an issue that needs to be considered for the next generation of rifles. It doesn’t make much sense to consider so many things now.
At this time, he pointed at the receiver cover because of another problem.
“Professor Liu, judging from the current overall architecture and technical route, the bolt frame of this gun may be very long. You see, from now on, the receiver cover is already this long. , this may cause a problem."
Professor Liu took it very seriously: "Director Gao, you said!"
"The bolt frame will occupy the total length of the gun, causing the aiming baseline to be shortened. It has an impact on aiming accuracy.”
The aiming baseline, for iron sights, is the distance from the rear sight to the front sight. Within the allowable range, the longer this distance, the better the aiming accuracy.
To put it simply, although the gun can shoot accurately, it is not good to aim accurately.
This was the case with the gun in the previous life. The long bolt frame at the rear and the long grenade adapter and flash suppressor at the front each occupied part of the gun length, resulting in a less than ideal aiming baseline length.
And the most unfair thing is that the adapter was of little use afterwards, because our first generation rifle grenades were not good, and the second generation was bumpy and basically not used.
Professor Liu looked at it, nodded and said: "What you said makes sense. We will pay attention to this matter when we enter the detailed design and try to take it into account."
It's enough to be able to achieve this step. In fact, aiming at the baseline is not a big problem, as long as we can improve as much as possible.
He clicked on the muzzle device of the concept gun: "Are you ready to load grenades here?"
How do you call grenades? When the gun is equipped with a large number of grenade launchers and disposable rocket launchers, After being installed, this thing doesn't have much meaning. Among these types of team attack firepower, rifle grenades seem to be the most practical, but in fact they are the worst. Later, the major powers did not pay much attention to them. .
The biggest problem with this thing is that the powerful one cannot hit far, and the far-reaching one has low power. Regardless of the distance, it cannot hit accurately, and its ballistic performance is extremely poor.
There is no need to talk about technical issues. From the analysis of energy conservation, we know that the launch energy comes from the point where it is originally used to hit a warhead of a few grams to hundreds to kilometers away. Children's propellant. But the grenade grenade weighs hundreds of kilograms, and it still relies on this propellant to travel hundreds of meters or even thousands of meters. If its comprehensive ballistic performance can be improved, then there is something wrong.
This is a bit similar to Gao Zhendong's previous life. The "regional" anti-aircraft missile Barak-8 imported by Zongsan relies entirely on wandering around. It is said to have a range of 70km. In fact, at that range it can only hit targets without maneuverability such as transport aircraft. , the military fan circle jokingly calls it a "walking bomb."
As for it being very common in some small countries or tribal conflicts, this is normal. It would be good if they can get weapons and ammunition, and they also need bicycles. This is no joke. For them, it is not uncommon for the conflicting parties to sit on both sides of the battle line with empty guns because they have run out of ammunition. You look at me and I look at you, staring at each other for several days or more.
However, at this time, it is not easy to criticize or cancel anything. At this time, at least in terms of the attack firepower of the existing team, on paper data, rifle grenades are still good, and they can hit infantry. It's not impossible to get an armored vehicle, it's better than nothing.
So he just put forward an opinion: "Professor Liu, if you are still working on this rifle grenade, I have a suggestion - you must not use blank ammunition to launch it, you must use live ammunition. Designs such as bomb catchers! "
Gao Zhendong's two "certainties" made Professor Liu pay attention. He frowned: "It is indeed the easiest and most convenient thing to prepare to use blank ammunition now. ”
Gao Zhendong said: "But in this way, the battle preparation for using rifle grenades will be very cumbersome and troublesome. Unloading the magazine, ejecting the bullet from the chamber, loading blank ammunition, plus preparing for the launch of the rifle grenade itself, this is very difficult on a battlefield where every second counts. , The impact on soldiers is too great. If this is done, many fighters will be fleeting. "
This is the difference between the perspectives of designers and users.
The designer's idea is that these things are not too troublesome, just take a while and it should be no problem.
The user's thinking is that the problem is huge and you'd better not cause me any trouble at all.
And the rifle grenade itself often needs to be opened or installed with shooting accessories.
For example, in sights, there are many images of rifle grenade shooting. There will be a long thing standing up on the body of the gun or the tail of the grenade. Because the trajectory of rifle grenades is very different from that of gun bullets, the sights are generally ordinary. It needs to be installed separately.
Professor Liu thought for a while and nodded: "What you said makes sense. I will solemnly explain this situation to the comrade in charge of grenades."
Gao Zhendong is not just Although he asked the question and did not talk about the plan, he still gave some suggestions: "If there is difficulty in catching the live ammunition, you can also use another method, the penetration type. Do not capture the warhead, let it pass directly through the middle of the rifle grenade. During the process of traveling, relying on friction to obtain launch energy is also a way. By the way, it is best to make the aiming attachment on the rifle grenade and make it foldable. "This method also has shortcomings, such as incomplete energy transfer. It's too controllable, but in Gao Zhendong's previous life, he also invested in practical rifle grenade launching technology.
As for the principle of ejecting live projectiles sideways, Gao Zhendong didn’t say it. It’s not very accurate to begin with. If you throw a high-speed projectile sideways, there will be Anyone who has studied conservation of momentum will understand the consequences.
Professor Liu's eyes widened suddenly: "Director Gao, your thinking is so subversive. You can always solve problems from angles that ordinary people can't think of. This is an interesting idea."
While admiring , while writing furiously, feeling happy, with this piece of scrap paper, I can rip off Lao Luo for three meals without any problem! Who is Lao Luo? Their school sells rifle grenades.
The students around him were also stunned by his fantastic idea. Is this the boss’s brain? Disrespect, disrespect.
Gao Zhendong keeps doing it, so I will give you another rifle grenade. I believe that with this and the disposable barrel, rifle grenades will become useless after the trial.
Based on current conditions, gun-mounted grenades are based on pure creativity and are not technically difficult.
"Professor Liu, I have a new idea, which is also to improve the blasting firepower of the team. Are you interested?" Gao Zhendong looked at Professor Liu with a smile. I don't believe you won't take the bait.
Professor Liu is so excited, eh? And this unexpected gain? Director Gao's ideas have always been both necessary and feasible. Even if they cannot be used due to environmental conditions, they are definitely good things.
He waved his hand and signaled to the students. They all listened carefully. Director Gao was about to output.
I turned my head, grabbed the pen, and turned the notebook to a new page: "Director Gao, I am not asking for nothing. I am interested in any ideas you have. I am all ears, all ears."
Gao Zhendong also picked up his pen and said: "Let's get a gun-mounted grenade launcher."
"Grenade launcher?" I've never heard of it.
“Yes, let’s make a suitable grenade. The caliber is 30~40mm. It can be made into a bullet-like bullet. Then we can make a simple launch tube and hang it under the firearm. Here!”
As he said this, he pointed the pen under the barrel and in front of the magazine.
“Huh?” Professor Liu looked at what Gao Zhendong’s pen pointed at and thought about it. The more he thought about it, the more wonderful this position became.
It is enough to hold a launch tube, does not damage the carrying length of the gun, does not damage the thickness of the gun, and has a certain impact on the center of gravity of the gun but not seriously.
From a staffing point of view, this thing is originally attached. Only a few firepower players in a squad need to be attached. It does not damage the overall firepower configuration of the squad. If it is available, it will be attached. If it is not available, it will not affect the gun itself. This is consistent with Rifle grenades have the same effect, but the fire response speed is much stronger than that of rifle grenades.
The students also discussed it enthusiastically.
"This is interesting. Except that it is a little less powerful, it is no worse than a rifle grenade, and its ballistic performance is world-class."
"That is, specially designed ammunition can definitely be used. The ballistics are well optimized. "
"If designed properly, it will be very powerful for anti-personnel use, and the caliber of the anti-blast grenade is not much larger than this. "
"It's also good for anti-armor. It has a caliber of 30~40mm and uses a shaped energy-piercing warhead. It's no problem against light armor, and it can also take damage into account."
This classmate must be good at studying, shaped energy-piercing warheads It is slightly different from shaped energy armor-breaking, and more similar to a self-forged fragmentation warhead. It is more suitable for anti-armor and anti-personnel ammunition, and has small requirements on the length of the projectile.
While listening to the students' discussion, I thought to myself, Professor Liu's face is getting more and more happy. Director Gao raised it well, and the students learned well!
"Director Gao, once this is done, I will use this thing as an accessory for the gun clan when I get back and start the project!"
This is the good thing about having a large and systematic project in hand. The gun-mounted grenade can be set up simply as an accessory system. The process is simple and the funds are relatively secure. Even if there is no new funds, it is enough to squeeze in a little bit here and there in a big project.
In particular, the gun-mounted grenade itself is a relatively simple thing. If they don't go to great lengths to optimize the grenade, they can make it very fast.
