Chapter 146

Taran is an English unit of weight. A Taran is about 1.77 grams of a metric unit of weight.

The stone bear said that there are more than 2 drans, which is about 4 grams.

Second lieutenant Ferguson said with a little disbelief: "boss, at present, we also try to charge too little, but the effect is very bad. The range of the shot is much lower, and the penetration is also much worse, especially because the power of the shot is insufficient, which will lead to a significant decline in accuracy. "

The stone bear nodded and said, "what you said is inevitable. That's why I asked you to develop a new rifle. The new rifle I asked you to develop is not only for the purpose of loading speed, but also to reduce the clearance between the bullet and the barrel as much as possible, so as to improve the utilization rate of gunpowder. In this way, the range, power and accuracy of the projectile can be guaranteed. "

"I guess what you can't imagine is that if the clearance between the bullet and the barrel is small enough, the effect of using more than 2 drans of gunpowder is much better than that of using 5 drans of gunpowder."

Lieutenant Ferguson continues to look at his boss. Obviously, if stone bear doesn't explain the reason to him, this stubborn guy will keep asking.

Stone bear naturally understood Ferguson's eyes. He laughed, picked up a small amount of black powder and continued to explain: "this small amount of powder is about more than 2 drans, which is about 4 grams. If the powder in my hand is black powder made with the best proportion, then it's just such a small amount of powder. After ignition, it's a small amount of powder, It can produce up to 280 liters of gas! Do you know what 280 liter gas is? It's about ten thousand times as much as this handful of gunpowder! "

"Ah Ferguson, as well as the clippers and the tough guys, were surprised.

"That's right, just a little bit of gunpowder, and then the volume will expand 10000 times in an instant! The most important thing is that the expansion speed of this gas is far faster than the speed of sound! If we can make use of all these gases, then you think about how powerful the bullet will be from the barrel? How far is the range? "

Lieutenant Ferguson took a dry swallow. "Boss, I'll listen to you!"

"Ha ha, of course you have to listen to me. Patrick, can you make gunpowder? "

"Yes! When I was in the army, I used to make my own gunpowder. "

"Don't worry, boss, even if I go back to Jamestown, I'm the only one who knows the data. And I'm only going to use that mix to make my own powder. "

"Well, remember that. Well, next, these nitrates and sulfur are left to you to make gunpowder. Well, what kind of charcoal do you need? Just give it to Kuaima or adamant. They will prepare it for you. "

"It's easy to say that the key to charcoal is the self-adhesive. Boss, I can't make granulated powder without the agent. "

Stone bear nodded and said: "this is no problem, I'm responsible for getting the private knot agent out for you. But I can't get the desensitizer out, mainly because I don't have the equipment here. But it doesn't matter if there is any desensitizer in black powder. It seems that there is no desensitizer in the powder you are using now, right

"Desensitizer?" Ferguson's face was blank. "What is that?"

Shi Xiong shakes his head helplessly. He accidentally makes another big oolong. Those fierce drugs of later generations all need to add desensitizer, but now there is only one kind of gunpowder in the world, that is black gunpowder. This thing is not as sensitive as those fierce drugs, so it doesn't need to add desensitizer.

"Well, take it as if I didn't say it. Well, it's a little bit of a hassle, but I promise it's OK. "

The so-called binder is the main medium for making black powder into granules. The earliest gunpowder binder was egg white.

However, it is obviously too extravagant to use egg white as a private caking agent. Although there are many chemical products used as private caking agent in later generations, the best private caking agent in this era is castor oil.

In the museum where the stone bear lived in the past, there are many records of our army beating little devils in those years. At that time, our army was very hard and the conditions were poor, but even under such conditions, our army successfully produced mengzha medicine.

Of course, in those days, the black powder made by our army was made with castor oil.

Although castor bean is native to Africa, with the advent of the era of great navigation, this kind of plant has appeared in America for a long time, but not many.

But it doesn't matter. There are lots of castor beans in Europe. Next time we trade with major hank, let him get some castor beans to squeeze oil by himself.

Anyway, I don't worry about gunpowder. After all, there are thousands of pounds of black gunpowder seized from the French this time. Even if the guns are scrapped, the gunpowder can't be used up.

Once new rifles are developed, the captured black powder will be enough for military training.

After coming out of the ship's warehouse, Shi Xiong took them to the warehouses of the other three ships. However, most of the cargo holds were filled with food, cloth, salt and other daily necessities.

Ferguson is not interested in these things, but fast horse and hard bone are happy. They seized so much grain and cloth all at once, and they were as excited as other people.

Ferguson is interested in the Wallace guns on the deck.

I have to admit that the British are not as good as the French in terms of making artillery. At present, in Europe, the highest gun manufacturing technology is the French.

Although Spain is the most powerful, the British defeated the French in the just concluded seven-year war, but the French military technology is the top in Europe. The Spanish and British, including the German and Dutch, are not as good as the French in this respect.

"It's a pity these are good guns! These guns are completely blind in the hands of the French. " Second lieutenant Ferguson stroked an 84mm Wallace gun with great emotion.

"These guns will be able to guard our tribe. Our leader has said that we should set up these guns around the tribe. If those chekasa dare to attack us, we will bombard them with guns! " Hard bone said excitedly beside Ferguson.

Lieutenant Ferguson nodded with a smile.

The power of these guns is pretty good. It's excellent to guard the tribe.

PS: I'll give you some bad news. Well, Lao Mo is going out to participate in a very important bidding today, which lasts about four or five days. To be honest, Lao Mo has saved manuscripts, but there are not many. Because summer is the peak production season of the company, and the old lady at home is not in good health, so there is less time for Lao Mo to code during this period of time, so naturally there are not many manuscripts saved. But this time I went to invite tenders for a lot of work, so Lao Mo estimated that there was almost no time for coding after I went out, so I had to use the manuscript. Therefore, in these four or five days, Lao Mo can only watch one day. Please understand this. However, after the bidding comes back, Lao Mo will have enough time. At that time, Lao Mo will try to make more yards. thank you!
