Nanming: I can build wonders

Chapter 61 Artillery Division

【recently】

Zheng Kezang used the study of "Dongning Infantry Exercise Code" as an excuse to let Dongning Military Academy absorb many grassroots officers from the former Yongwei Town, Qiu Jiayi Army, and Zhu Tiangui's Department.

There was no voice of objection from any department, because Zheng Kezang said: Only after learning new operation methods can new equipment be distributed.

Mastering the logistics is mastering the lifeline, these arrogant soldiers are now being controlled by him to death.

The most important reason why Zheng Kezang is so active in letting them come for further studies is the special buff of Dongning Military Academy. Officers from this military academy have +20% loyalty to Zheng Kezang.

With this buff, as long as the officers who come here to take classes and graduate, their loyalty can be greatly improved.

The buff of Dongning Military Academy can not be covered by all soldiers, but it is really useful.

When other places are conquered in the future, more military academies should be built, with abundant martial arts!

In addition to officers, Zheng Kezang also recruited excellent gunners from various ministries and established an artillery department. After they finished their studies, they would be sent back to various ministries to serve as artillery officers and teachers.

Today the weather is better, Zheng Kezang personally came to Artillery Division to see how they train.

Qin Zhiguo, Commander of the Artillery Battalion of the Guards Army, was also on site to observe.

Soon, he discovered a problem. Since the cannons of this era were all solid bullets, the emphasis was on impact, and they were mainly used to attack city walls, so there was not much requirement for the aiming head.

Although these gunners are experienced, their shooting depends entirely on experience. They judge the angle at which the shell is fired, how far it can hit, how high it can shoot, etc. based on experience.

This kind of operation mostly depends on experience and feeling, and the error is very large, whether you can hit it depends on luck.

In this case, their experience is not suitable for the whole army to promote.

Moreover, craftsmen such as Su Laocheng have successfully developed the flowering shell technology, which has the addition of sweet gunpowder and is extremely lethal, which has been fully demonstrated in the Battle of Zhugang.

Therefore, the artillery in the future war mode must be accurate, and the shells must be aimed at the opponent's infantry.

Speaking of which, flowering shells existed at the end of the Ming Dynasty. Zuo Zongtang unearthed more than a hundred flowering shells from a Ming Dynasty fort site when he was suppressing the rebellion in the northwest. , and even bullied by the great powers.

It seems that Zheng Kezang must personally teach the gunners the great subject of mathematics.

As a science student, Zheng Kezang still remembers this knowledge, so he just needs to get a textbook by himself.

It doesn't matter that the soldiers manipulating the cannon don't need to learn too much, as long as they learn trigonometry and parabola, it may increase the hit rate of the cannon by a large margin!

Zheng Kezang cleared his throat, and suddenly said to Qin Zhiguo: "Zhiguo, call all the students of the Artillery Division. These days, the supervisory state will concentrate on teaching them. In short, we must learn a lot about parabolas as soon as possible. To increase the hit rate of shells!"

"parabola?"

Hearing a new term popped out of Zheng Kezang's mouth, Qin Zhiguo just felt bewildered.

"This is a thing that can improve the hit rate of cannons! Remember the Arabic numerals you have learned before, that is the foundation." Zheng Kezang explained.

In order to make it easier for his artillery officer Qin Zhiguo to understand, Zheng Kezang directly drew a picture for him to explain.

But when he drew this picture, he said parabola, what initial velocity, what acceleration of gravity... After a lot of calculations, it didn't take long for Qin Zhiguo to be confused!
"Principal, can this... be done?" Qin Zhiguo asked hesitantly, "Can we calculate where the shells landed?"

"Ninety-nine are not far from ten!" Zheng Kezang replied.

This is actually a very simple parabolic problem. The mass, initial velocity, and angle of the warhead are known, and then a high school student can calculate the trajectory.

Soon, Qin Zhiguo, who had just mastered mathematics, fell into the vast ocean of parabola knowledge and couldn't extricate himself. While calculating, the two operated the Hongyi cannon and found that the shooting was really accurate.

"Principal, you are really talented. With such a unique skill, it will be difficult for the Tartars!" Qin Zhiguo said excitedly.

"Don't get excited, the most urgent task is how to teach these gunners how to count parabolas and functions." Zheng Kezang said calmly.

"Principal, I have an idea. Let the accountant of the logistics department teach them the usage of Arabic numerals first, so as to lay the foundation, so that they can take your class." Qin Zhiguo suggested.

"Good idea, Zhiguo, I'll leave this to you." Zheng Kezang patted him on the shoulder.

"Yes, Principal!" Qin Zhiguo gave a standard salute.

Two days later, Zheng Kezang saw that they had almost mastered numbers, so he started teaching.

There are two big parts: one is parabola and the other is trigonometric functions.

Then I don’t talk about principles, theorems, and the like.

If this is true, then one by one, one has to go back and talk about both junior high school physics and mathematics.

What Zheng Kezang talked about was the formula, let everyone remember to memorize it, and then put which number, and where to put the number after it is calculated, so that it will come out after rote.

Zheng Kezang originally thought that it would be good if seven or eight of the hundreds of gunners could learn it.

As a result, on the second day, Zheng Kezang was surprised to find that half of them who had no foundation in mathematics and physics could do the math, and some of them could do it quite quickly.

Zheng Kezang believes that this is because the calculation methods are the same and the process is the same. The only thing that changes is the number, which can be recorded after several calculations.

On the other hand, the temptation of money was too great, which stimulated their potential. Zheng Kezang told them before the class started: the learned gunners can receive two taels of silver.

In order to get the money, many of these gunners stayed up all night last night, and all of them lit oil lamps to write and calculate.

So much so that when Chen Wei, the instructor of the military academy, was inspecting last night, he found it strange that the barracks of the Artillery Division were brightly lit, so he hurried over and asked, "What are you crazy about? You are writing and drawing here in the middle of the night, writing a review or something? "

The veteran of the artillery department came up and explained: "Teacher, didn't the headmaster let us in the artillery department figure out the parabola thoroughly? We are all studying this!"

Chen Wei suddenly realized that he had also heard about this matter. Since the principal Zheng Kezang made the matter, he didn't want to interfere too much, so he said: "Everyone, go to bed early, so don't affect the rest of the infantry and cavalry students."

After Zheng Kezang found out about this, he called it internal. No wonder everyone had dark circles the next day. It was only the seventeenth century, and they were rolled up. Sure enough, money was the only productive force.

What is learned on paper is superficial, and I know that this matter must be practiced. It is only the beginning for gunners to learn parabola and trigonometric functions. How to apply them in actual combat is the key.

They still have a long way to go.

"Zhiguo, your task is very heavy, understand?" Zheng Kezang watched the artillerymen's fiery training, and said to Qin Zhiguo beside him.

"Understood, I promise to complete the principal's task!"
