Bright Sword starts with the grenade flat.

Chapter 38 The knowledgeable Zhao Gang

However, just when Li Yunlong scratched his head and couldn't understand what Liu Xiu was doing, Zhao Gang, who was watching from the side, suddenly said:

"Isn't this the Monroe effect?"

When Liu Xiu heard Zhao Gang's words, he was immediately shocked. Could it be that Zhao Gang was also a time traveler like him? However, Liu Xiu threw this idea away after thinking about it. Maybe Zhao Gang saw Monro The published paper may not be certain, after all, the Monroe effect was discovered in 1888, and according to the habits of Western scientists.

Ninety-nine percent of this kind of new discovery is to publish a paper to gain fame, so it is not unusual for it to be known for more than fifty years.

Sure enough, when Zhao Gang blurted out these words, Li Yunlong on the side immediately asked:

"Old Zhao, what is this Monroe effect?"

"The Monroe effect is not a thing, but a phenomenon caused by the explosion of explosives, which will form a high-temperature and high-pressure airflow along the indented groove..."

But before Zhao Gang finished speaking, Li Yunlong, who had a keen eye for war, suddenly slapped his thigh and said happily:

"Can you put this thing on a grenade, so that when you encounter the Japs' tanks in the future, you don't have to hold the explosive packs and fight with the Japs' tanks!"

Regarding Li Yunlong's proposal, Liu Xiu could only call out for good guys in his heart. You must know that the Monroe effect, that is, the first place where shaped energy-breaking armor-breaking bullets were used was not the American bazooka rocket launcher or the iron fist of the United States. Recoilless rifle.

Because the Iron Fist of Deguo did not enter the battlefield until 1943, and even the earlier Bazooka was only one year earlier than the Iron Fist, that is, in 1942, but it was the first to appear on the battlefield. But it is an anti-tank grenade that appeared in 1941.

Because they didn't find a suitable throwing device, the giant bear country had no choice but to use a stupid method, that is, to make it into the shape of a grenade and rely on human power to throw it.

It's just that armor-piercing grenades are directional, and the grenades fly around in the air when thrown. Therefore, in order to ensure accuracy, a small parachute is added behind the grenade to ensure that the direction of its armor-piercing jet is Against the tank.

It's just that this kind of anti-tank grenade is very heavy and heavy, so it can't be thrown far at all. Even if a strong person can throw it 20 meters, it will be fine. Of course, due to its weight, the penetration of its armor-piercing jet is also limited. One hundred and seventy millimeters, of course, this is enough for tank armor that was generally less than 100 millimeters during World War II.

It's just that this kind of bulky anti-tank grenade was too difficult to operate on the battlefield, so it was short-lived with the emergence of anti-tank rocket launchers.

The real purpose of Liu Xiu's making this shaped armor-piercing projectile was to install it on the Jaap's grenade canister, and Liu Xiu had also seen the 50mm grenade dedicated to the Jaap's grenade canister. The internal structure is also very clear.

Therefore, it is very convenient to change an ordinary anti-personnel blasting grenade into a shaped armor-piercing grenade. You only need to put a conical copper metal cover inside to turn it into a shaped armor-breaking grenade.

So after Li Yunlong said this, Liu Xiu immediately shook his head and said:

"Captain, such a structure cannot be placed on a grenade, because the grenade rotates when thrown, and the direction of the cone's bell mouth must be specified! So I think we can put the little devil's grenade If you modify the inside of the shell, you should be able to turn it into a shell that can be used for hitting tanks!"

Zhao Gang on the side shook his head and said:
  "That's not possible! This grenade can fire in a straight direction like a mortar, so it's not easy to aim at a tank!" Liu Xiugang wanted to explain this, but Li Yunlong on the side said:
  "Who said that the grenade can only be erect and fired in a straight direction? It can also be fired when it is laid flat. The recoil of this thing is not very big. Just put more cotton on it and the problem will be solved!"

After that, Li Yunlong said to Liu Xiu again:

"I know you kid has a lot of clever ideas. If you have an idea, go ahead and do it boldly. I'll give you three grenades to do research on, so don't let me live up to my expectations!"

Liu Xiu had no choice but to nod in agreement to Li Yunlong's words, saying that he would do his best.

After that, Li Yunlong took Zhao Gang and left, and Liu Xiu expressed no pressure to use the grenade from the grenade to transform the shaped armor-breaking grenade.

After all, this is processing brass, not iron, and there are no high requirements for accuracy, so the tapered brass cover can be made using the sand mold casting method.

After all, Liu Xiu had successfully poured a brass muffler using sand molding before. With his previous experience, it would be much easier to do it again, and the crucible used for pouring was not that particular. He just needed a clay bowl. , after all, the melting point of clay is higher than that of iron!
  So I made a clay bowl and put a few brass bullet casings in it, and then put it in the stove. After a while, it turned into copper water. After all, if the charcoal fire couldn't melt the brass, how was the ancient bronze tripod poured? Of!

Of course, before pouring the brass conical cover, you have to go to Wang Chengzhu and ask him for the three grenades approved by Li Yunlong, otherwise it will be difficult to determine the size of the brass conical cover.

However, Wang Chengzhu was puzzled that Liu Xiu asked him for three grenades, so he asked curiously:

"Liu Wazi, why do you want three grenades?"

Liu Xiu said impatiently:
  "Oh, Brother Zhuzhu, if this is approved by the regiment leader, just hurry up and get it for me. Whether you can use a grenade to fight tanks next year depends entirely on these three grenades!"

"What! Don't fool us about the grenade hitting the tank. We are regular troops after all. Let alone the grenade. Back then, I couldn't even blast away the little devil's Bean Tank with a 60mm mortar. You That grenade hitting a tank is just fooling the devil!"

However, Liu Xiu, who was anxious to get armor-breaking grenades, had no intention of continuing to argue with Wang Chengzhu. He immediately walked directly to the room where the artillery discharged ammunition, opened the box, grabbed three grenades, and left.

You must know that there are only three days before the Chinese New Year, and it will be April 1st after the Chinese New Year. If Liu Xiu comes out with the anti-tank grenade this year, wouldn't it be two years earlier than the bazooka anti-tank rocket launcher? !
  This will give you the confidence to brag in the future, right? The bazooka is nothing, our anti-tank grenade is two years older than your bazooka.

Liu Xiu, who returned to his house with three grenades, put the other two away, then started dismantling them with one in his hand.

The first thing to dismantle is naturally the collision fuse on the head of the grenade. Only when this thing is dismantled can the grenade be considered safe. Otherwise, if he misses and falls headfirst to the ground, Liu Xiu can travel through time again!

Of course, the little devil has naturally taken this into consideration, so he also added a safety pin to the grenade fuse. It will only be unplugged before use. When it is plugged in, it will not explode even if it falls to the ground.
