On the field of military school, the discussion continues.

Li Daoxuan thought for a while and said: "It should be the thrust generated by the combustion of gunpowder that the rocket can be launched quickly." ”

Cui Wenqing said with a smile: "Captain Li's words can only be said to be half right, in fact, the reason why the rocket can fly is mainly because of the principle of recoil. ”

As if knowing that they would definitely ask, Cui Wenqing continued to explain: "The so-called recoil, we have to mention the law of conservation of momentum, if an item is not subject to external force or the vector sum of the external force is zero, then the total momentum of the item remains unchanged, and it is also stationary, but after the rocket ignites the gunpowder, the gunpowder energy is shot out through the small hole reserved by the cylinder, which forms a recoil force and drives the rocket to fly forward." ”

Seeing that Zhi Zhao and the others were all looking at him dumbfounded, obviously not understanding, Cui Wenqing couldn't help but sigh and said with a smile: "The theory is too profound, just change it to a simple speech, for example, lady, let's ask you a question first, when you are fighting with the enemy generals, what is the biggest feeling when the weapons in your hands fight each other?" ”

Zhi Zhao pondered silently for a moment, and said: "It should be a countershock, if the martial arts are not good, maybe you will be shocked to the point that your mouth is numb, your arm is pantothenic, and if you are not good, you will not be able to hold the weapon and you will be defeated." ”

Cui Wenqing smiled and said: "Yes, in fact, this recoil is similar to the meaning of reshock, so the rocket can fly out." ”

"But ......" Speaking of this, Cui Wenqing smiled and asked in a deep voice: "If we seal the small hole reserved by the cylinder and then ignite the lead, guess what the result will be?" ”

Li Daoxuan didn't think about it, so he said: "It will explode, just like a firecracker." ”

"That's right." Cui Wenqing nodded with satisfaction, and said loudly with a rocket: "This kind of rocket makes good use of the recoil force generated by the explosion of gunpowder to shoot and kill the enemy, but in fact, how powerful can a single arrow be produced even if it hits the target?" At most, you can only kill one person, but if you combine the recoil force with the explosive power of gunpowder, the effect will be quite amazing! ”

Li Daoxuan was stunned and asked, "What does my uncle mean by this?" Why can't I understand? ”

Cui Wenqing smiled and explained: "Actually, I think, you can add another section in the cylinder, and leave no holes in the seams, and when the rocket flies to the enemy formation, it can just ignite the added part, which suddenly causes a violent explosion, and the power of the rocket is naturally greatly improved." ”

When the words fell, Li Daoxuan and Shen Team were both thoughtful, obviously shocked by Cui Wenqing's whimsical idea.

As we all know, ancient rockets can be described as the ancestors of modern rockets, and their principles are basically the same.

But no matter what kind of rocket it is, it almost does not have much lethality and is rarely used in the military.

However, during World War II, the Germans came up with a way to improve the rocket to give it another branch, that is, missiles.

The original missile used the recoil force to fly, but compared to the rocket, it had a separate explosive device to increase the explosive power after concentrating the target.

Today, Cui Wenqing said this and proposed to set up a simple explosive device for the rocket, which can be said to have opened up a new world for Li Daoxuan and Shen Teamzheng's thinking, and also opened up a new world for the use of rockets to kill the enemy, which made the two of them think deeply.

After half a sound, Team Shen came back to his senses first, frowning Bai Huahua's brows and asked: "Aunt Cui, although your idea is good, but even if you add the rocket to the explosive device you said, its power is not complimentary, because of its ability to fly, it is determined that it cannot be too heavy, so the explosive device cannot use too much gunpowder, even if it can explode, the lethality to the enemy is very limited." ”

"That's right," Li Daoxuan nodded in agreement, "It's like an artillery battle, even if it's a lot bigger, what kind of lethality can it be thrown into the enemy group?" ”

Li Daoxuan's words can be said to be simplified, and it also made Zhezhao, a layman, understand it instantly.

Indeed, isn't the explosive device mentioned by Cui Wenqing just an artillery battle? What effect can there be when there is a sound in the air, but there is no power?

For a while, Cui Wenqing's words just now were questioned, and even Zhi Zhao couldn't help frowning and waiting for his answer.

Hearing their questions, Cui Wenqing relieved his heart, in fact, as far as he was concerned, what he was most afraid of was playing the piano to the cow and having no work.

Since Li Daoxuan and others were able to ask questions, it meant that they at least understood what they meant, and it was naturally more convenient to communicate.

Cui Wenqing said with a smile: "What everyone said is extremely true, indeed, what kind of power can a cannon battle be thrown into the enemy group?" But the cannon I am talking about is not an ordinary cannon battle, nor is it made of alum paper, but a layer of iron wrapped in it. ”

"Iron Shell?" Li Daoxuan and Team Shen were surprised at the same time, looking at each other in confusion.

Cui Wenqing said seductively: "Let me ask you, how would you feel if you were hit by ordinary firecracker debris at close range?" ”

Li Daoxuan frowned and said, "Naturally, it is very painful, once my arm was hit by debris and was purple for a few days. ”

Cui Wenqing said with a smile: "It's just a soft alum paper, and it still has such power when it ejects after the explosion, if you replace the alum paper with an iron piece, you can imagine its true power." ”

Like a heavy thunder suddenly passing by, Li Daoxuan and Shen Zheng's bodies shook at the same time, and their eyes lit up instantly.

The soft alum paper is still painful under the explosive power of the cannonball, and if you take iron sheets, wouldn't it be ...... Broken gold and jade?

Thinking of this, the hazy clouds in Li Jingxuan's heart were suddenly blown away, he was stunned, his eyes stared at Cui Wenqing for a while, and he suddenly slapped his thigh so much that he almost jumped up in surprise: "Yes, why can't you use iron shells to make artillery battles?" Why didn't I think of that? Uncle, how could you think of such a wonderful way? What a genius idea! ”

Overjoyed, his words suddenly became incoherent, and his voice took on a slight tremble.

Zhi Zhao was also shocked for a long time, and asked in the middle of the voice just now: "Husband, if you replace the artillery battle with an iron shell, can you penetrate the armor of ordinary military generals?" ”

Cui Wenqing thought for a while, nodded and said, "Although I have never tried it, I believe that it should be possible, and in addition, we can still ...... Let's call it an iron-clad cannon battle, you can put a relatively small iron lump in the iron-shell cannon battle, and when it explodes, all the iron lumps will shoot out, and the power will be increased a lot. ”
