Yang Mingzhi carried out this seminar with strong enthusiasm. Pen × fun × Pavilion www. ｂｉｑｕｇｅ。 ｉｎｆｏ

The rocket propellant improvement program came to an end, and the discussion focused on bullets.

"The arsenal is able to produce brittle bullets that can tear apart the enemy and are more lethal than ordinary ammunition. If we are able to make this type of ammunition from existing materials, we should further improve it so that all the bullets produced can quickly disintegrate when they hit the enemy. ”

"It's a good idea, but how do we get it done." "Thirty percent of the bullets that ended the experiment did not shatter. And the fragmentation of the broken warhead is large, as if a cylindrical warhead broke from the middle. ”

"Then find a way to split it from the top, and then split it as a whole."

The focus of the question shifted to how to make the warhead explode from the top, and some people even quipped: "It's better to replace the warhead with a detonator." ”

Everyone laughed, and Yang Mingzhi also smiled and waved his hand to deny this conjecture. However, a detonator is inserted in the bullet head, and in the Winchester series of lever rifles, there is indeed a matching bullet with a detonator. It was thought that such a warhead could snipe at the enemy's ammunition box, causing a large explosion, or hitting the enemy to create a bowl-sized hole

This technology was too advanced at the end of the 19th century, and later in the anti-materiel sniper rifle, this ammunition was realized, but a hundred years later.

Yang Mingzhi regained his demeanor and said: "The bullet will deform the moment it hits the enemy, and this kind of warhead has already appeared. It is characterized by a dent in the head and is filled with soft and easily deformable lead. What we lack most is lead, and if we don't lack it, we can also make lead cores and steel bullets. ”

The people from the arsenal nodded, acknowledging the point. One person asked: "The commander mentioned the air-tipped bullet, if it is just to drill a hole in the warhead, the processing technology is convenient and only a small change is needed." ”

Yang Mingzhi shook his fingers, and he motioned to the people from the arsenal and the weapons design bureau to listen carefully.

"The ammunition I'm talking about isn't purely empty-tipped, if you talk about structure, it does have a groove. But I'm going to make it work like a dummy bullet, because there's a lack of soft lead, so we'll have to find a different way. Yang Mingzhi's eyes turned to Rygushkov. What are the tin reserves in the arsenal now? ”

"Tin has a lot more storage than lead." The explanation of the arsenal is very satisfactory, tin is a very common metal, and for the needs of industry, the blacksmith village originally stocked a lot. In addition, a large amount of metal was brought from the ruins of the city of Homnich, among which was tin. Rygushkov seemed to think of something, and quickly asked: "Does the chief want to produce bronze?" It is indeed not as hard as pig iron. ”

"No!" Yang Mingzhi smiled reassuringly, as if everything was under control. He shook his finger: "Tin is unusually soft and has a very low melting point, it cannot be used as a bullet, but it can be used as a filler for the middle cavity of an empty tip bullet." ”

The notebook was spread out on the conference table, and Yang Mingzhi took out a pen and drew a good bullet in his mind with his skillful hands.

Everyone immediately stood up and poked their heads out, staring at the tip of the chief's pen. I saw the shape of a bullet drawn, and at the warhead, everything was different.

Yang Mingzhi drew three views, marked the approximate length of each size, and briefly wrote down the processing technology.

I saw that the warhead was still a cylindrical metal, the original round head was ground out of a flat surface, and the middle arrow was chiseled out of a hole by a drill bit. The hole is not empty, it is filled with tin. But this is still not over, there are a few more grooves on the outside of the warhead, and people immediately think that this is completely the same as the fragmentation groove of the grenade!

For professionals, a process card and a three-dimensional view of the workpiece are worth a thousand words.

Popov listened to the chief's sigh for a long time, and was hung up on his appetite, and now he slapped his thigh with excitement when he saw the drawings.

"The chief of staff is the chief of staff, if I produce such a bullet, the tin under high pressure after hitting the enemy will liquefy, and the powerful hydraulic pressure will squeeze the iron around it and crack along the reserved fragmentation slots, and eight fragmentation slots are drawn in this diagram, which will naturally be divided into eight small warheads, plus the iron of the base, it will be nine warheads. One shot we hit the enemy is equivalent to hitting nine. ”

"And depending on the angle of hit, the pattern of shrapnel dispersion is also different, which is simply irregular." Yang Mingzhi is really proud now, and the technologies he knows are not mysterious, because in the original plane, the Americans invented this kind of perverted weapon.

Later, dummy bombs were banned in many countries, and rumors were also rumored to be used in the United States. In fact, this was not the case, and they invented more lethal warheads, one of which was a bullet split by a prefabricated fragment in one hit, giving small-caliber warheads the power of shotguns. Ironically, the idea behind this bullet is to ensure that women can shoot and kill criminals with a single shot when they defend themselves with a gun.

Carambola and Natasha, who were temporarily in charge of serving tea and water, knew that the men were smoking cigarettes and talking in Russian, but they really didn't understand the technical terms.

Seeing her husband surrounded by a group of people, they are all high-level intellectuals, which shows her husband's status in the crowd. "Sure enough, knowledge is power." Carambola was happy for her husband, said casually, and continued to be busy with Natasha about her own business.

The two girls prefer to stay with the commander, because of their feelings, and because of the military order.

Yang Mingzhi, who was excited, naturally forgot about them, and didn't notice until he was given warm water that had just been boiled and cooled.

"You two better go home first, tell the cafeteria by the way, and send dinner to the Weapons Design Bureau, we have a long meeting today!"

Carambola pouted, it's really worrying that her husband is busy, tired today, and will be sluggish tomorrow.

The smoke in this room was so heavy that the two girls hummed and did not linger longer, and left the design bureau with an order.

"That's it! Our girls are out for now, and now we can move on to the discussion. An enthusiastic Yang Mingzhi returned to his seat, at which point Popov asked the key question.

Because the gyroscopic effect of the bullet is the most important thing to maintain the stable flight of the warhead, there is a hole in the middle that will affect the flight of the bullet, and the theoretical effect will be most greatly offset by the gyroscopic effect. However, if this hole is slightly eccentric, it will cause the bullet to lose stability, and it is easy to become a smoothbore gun after discharge.

Yang Mingzhi had already thought of this kind of money situation. "In the production plan, we do have to drill holes by hand, but we are not purely hand-held drills, here we can use woodworking lathes, and we have several such lathes in our arsenal. Based on the properties of the material, it is entirely possible to drill holes in woodworking lathes to ensure that the holes are not eccentric. ”

"That's it! I'm totally up to the task. "Rigushkov saw great promise for this bullet, which was simple to machine, nothing more than low-quality cast iron drilling and rifling, which could be done entirely on woodworking lathes.

Yang Mingzhi looked at the enthusiastic one and was very satisfied. "Riguskov, I think you should set up a new team to modify warheads full-time, and if the output can keep up, we will do the same with future reloading bombs. Since the chamber pressure has been greatly reduced due to the use of black powder, and the speed of chambering has also degraded to a few decades ago, the only way out is to modify the bullet. ”

The design of the new projectile was launched earlier than the mass-destruction projectile, thanks to the fact that it could be produced immediately under existing conditions. Even inferior warheads are harder than wood, and warheads of various types can be shown only on high-speed hits.

According to its composition, Yang Mingzhi called the new bullet "tin core clad steel empty tip bullet", and perhaps within a few days, a large number of such bullets will be off the production line.

Bullets are the foundation of ordinary infantry, and with it, Yang Mingzhi believes that the combat effectiveness of the swamp troops will be improved again.
