Chapter 1649： Come out, a modified version of the tiger squat gun

Chapter 1649 Come out, an improved version of the tiger crouching gun

"The technique of cannon diameter multiplication? What is this technique? It has never been heard of before. Yang Yi has such a big tone, how dare he call it the fundamental principle of artillery? Our ancestors didn't know this artillery multiplication technique before, isn't it the same? Did the artillery come out? Speaking of which, Yangyi’s artillery was learned from our ancestors.”

Zhang Hong murmured a few words in dissatisfaction, but before Zhu Pingan could speak, he narrowed his one-eyed eyes again, and then nodded thoughtfully, "Yes, foreigners are good at calculations, and they always talk about competitions. Ernes, when I was stealing a teacher from Nanyang before, I always took out a ghost drawing talisman before seeing foreigners making artillery parts. At first, I thought that foreigners believed in religion and had to chant spells and cast spells before making artillery. Now that I think about it, it is about calculating the multiple diameter of artillery. Yes."

Zhu Pingan nodded noncommittally, and said softly, "Maybe, I have never met foreign craftsmen, and I don't know their habits, but according to the records of foreign firearms, they really like to use public calculations to calculate."

"My lord, please teach me how to double the diameter of artillery." Zhang Hong pleaded, "If it is true as what the foreigners said, I will be able to manufacture artillery that is not weaker than the foreigners, so as not to embarrass my ancestors."

"Of course, firearms originated from China. I believe that Mr. Zhang, you will be able to develop firearms that are not weaker than foreigners. I will tell you everything I know. However, I am also very impressed with the art of double-caliber artillery. I don’t know much about it, but I don’t know why. The so-called art of double diameter of artillery refers to how many times the thickness of the walls of the gun body is times the diameter of the muzzle. It mainly refers to the ratio of the length of the gun body to the thickness of the muzzle. I still I noticed it in the latest and most cutting-edge artillery classics of the Ming Dynasty. It contains: "Yangyi casts artillery guns. The length, size, thickness, and thickness are measured carefully. They did not dare to rely on their cleverness to create false ones, so as to make mistakes. They must rely on it." It must be deduced by comparing the illuminance of the true tradition. The method is not based on the size, but only on the diameter of the muzzle. It is said that the size of different guns is different.' I read many classics, and my understanding is that only according to a scientific Only by designing the dimensions of each part of the cannon with a fixed ratio can the cannon achieve the best balance between weight and power. Otherwise, the gunpowder will either have too thick a wall, which will only increase the weight of the cannon, or the wall thickness will be insufficient, which will easily cause the risk of blasting the chamber " Zhu Pingan nodded and said slowly.

Zhang Hong listened with a serious face. Hearing this, he couldn't help feeling a lot of emotion. He was greatly inspired and asked quickly, "So there is such a saying about making cannons. No wonder I always thought that cannons were either too heavy or easy to explode. I don't know the proportion geometry is the best balance."

"I don't know how to calculate the ratio of the specific artillery multiple diameter. At about 22 times, the power range can reach a relatively ideal value. In addition, it is recorded in my latest and most cutting-edge artillery book in Ming Dynasty, "Yangyi has a method of proportional calculation, based on the bore diameter of the gun. For example, a gun, agreed If the bore diameter is 1 inch, the gun wall should be 1 inch thick near the tail, 7.5 centimeters thick near the ears, and 5 minutes thick near the mouth. Therefore, from the outside, the gun muzzle is sharp and the tail is plump. The diameter of the ear circle The length of the ear should be one inch long, and the ratio should be used as a fixed rate step." Zhu Pingan said a little embarrassedly, there is no way he was a liberal arts student, and he was interested in firearms in modern times and saw them on the Internet.

It's also thanks to my good memory, I can barely remember some, otherwise I'm afraid it will be even more embarrassing.

"The multiple diameter of the gun body and the muzzle is about 22 times, and the power range reaches an ideal value. Excuse me, my lord, does the gun body here refer to the length of the barrel or the overall length of the gun?"

Zhang Hong asked for advice.

I am truly worthy of someone who has secretly learned artillery technology from Hongmaoyi. This question is professionally asked.

"It refers to the length of the barrel." Zhu Pingan thought for a while, and made sure that he did not answer wrongly.

"Thank you, my lord. If the technique of double diameter cannon is confirmed, it is really an incredible technology. No matter how long the cannon body is, how powerful it is, and the geometry of iron and copper, the key problems of these cannons will be solved. In the past, when developing cannons, I always feel that the heavier the artillery, the thicker the muzzle, the thicker the gun body, the more gunpowder it contains, the greater the power of the artillery, so the artillery is always thicker, the muzzle is thicker, but the length of the gun body is ignored. No wonder, in the past I always feel that although the artillery is heavy and thick, its power is not as good as expected, and incidents of bombing often occur. It turns out that the thicker the artillery, the better.”

Zhang Hong said excitedly, and the more he talked, the more excited he became, "The double-diameter technology of this artillery is incredible. No wonder the Hongmaoyi's artillery is better than ours. No wonder the Hongmaoyi's artillery is a bit different in size and length. It turns out that there is something. Stuff. At present, the artillery of my Ming Dynasty is too bulky and has limited power. The artillery for city defense needs to be powerful, and the artillery for siege and field battles needs to be flexible and easy to carry. Find a balance between them, reduce the weight of the artillery, increase the power of the artillery, and greatly improve the city fire prevention artillery and field artillery.”

Zhang Hong was gearing up excitedly, preparing to do a lot of work to improve both the city defense artillery and the field artillery.

"Mr. Zhang, the main enemy at present is the Japanese pirates. I want Mr. Zhang to help me develop a portable artillery that is suitable for the watery, forested and hilly terrain in the South of the Wa River. It is easy to carry and carry. The current Fran cannon Although it is powerful, it is too cumbersome, and the range of the bowl mouth gun is too short, and its power is limited. Right now, there is an urgent need for a new type of lightweight artillery to fight Japanese pirates."

Zhu Pingan saw that Mr. Zhang was very ambitious and wanted to develop and improve artillery such as city defense artillery and field artillery without sweating on his forehead. Even with the technique of double diameter of artillery, improving artillery cannot be completed overnight. It will not take ten years Eight years is not enough.

At present, the Japanese pirates are urgently needed, and the Japanese pirates are becoming more and more corrupt and serious, and there is not so much time.

So Zhu Pingan directly pointed out the direction, and asked Zhang Hong to develop a cannon suitable for the terrain in the south of the Yangtze River.

Rather than spending time, effort and money developing a wide variety of artillery, it is better to develop a single artillery. The south of the Yangtze River is mostly hills, forests and paddy fields, etc., and heavy city defense artillery and field artillery are not suitable, only light artillery is suitable.

"I was looking through the ancient books of Europa and other Yangyi in the library of the Hanlin Academy, and found that one of them recorded a sketch of a cannon, which was a light artillery that Yangyi was developing. In order to facilitate shooting, the artillery was placed in a fixed position. The posture is like a tiger squatting, launching at an upward angle."

Zhu Pingan gave a brief description of the tiger crouching cannon that Qi Jiguang would invent and commonly used in the future, and asked Zhang Hong to use the more advanced cannon double diameter technique to improve and develop it. I believe he will not let himself down.

"My lord, don't worry, the grass people will live up to your expectations." Zhang Hong clenched his fists hard, hammered his chest heavily, and said loudly.
