Chapter 1649 Come out, improved version of Tiger Crouching Cannon
"The art of doubling the diameter of artillery? What kind of art is this? How come it has never been heard of before. The foreigners dare to call it the fundamental principle of artillery with such a big tone? Our ancestors didn't know this kind of artillery diameter-doubling technology before, didn't they also create artillery? Speaking of which, the foreigners We still learned our artillery from our ancestors."
Zhang Hong muttered a few words in dissatisfaction, but before Zhu Pingan could speak, he narrowed his one eye again, and then murmured thoughtfully. He nodded and said, "Yes, foreigners are good at calculations and always talk about Sainz. I saw foreigners making artillery when I stole troops from Nanyang." I always took out a book of ghost drawings to calculate the parts. At first I thought that foreigners were religious and had to recite spells before making artillery pieces. "
Zhu Ping'an was noncommittal. He nodded and said softly, "Maybe. I have never seen 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."
"Please teach me how to multiply the diameter of artillery," Zhang Hong said with a face of pleading. As the foreigners say, I will definitely be able to create artillery that is not weaker than the foreigners and will not embarrass my ancestors.”
"Of course, firearms originate from China. I believe that Mr. Zhang, you will be able to develop firearms that are not weaker than those of foreigners. I will tell you everything I know. However, I am also familiar with the art of doubling the caliber of artillery. I only know a little bit about it, but I don’t know why it is so called. Technique refers to how many times the muzzle caliber is the wall thickness of the gun body. It mainly refers to the ratio of the gun body length to the muzzle thickness. I noticed this in one of the latest and most cutting-edge artillery classics in my Ming Dynasty. Contains: "When the foreign barbarians cast cannons, they were very careful in measuring the length, size, thickness and thickness." Seriously, don't dare to rely on clever creations and make mistakes, and you must rely on certain true teachings and comparisons. The method is not based on the size, but only on the diameter of the gun's mouth. It means that the size of each gun is different. Therefore. 'I read many classics and understood that there is only one scientific method. Only by designing the dimensions of each part of the artillery in a fixed proportion can the artillery achieve the best balance between weight and power. Otherwise, the gunpowder wall will either be too thick, which will only increase the weight of the gun body, or the wall thickness will be insufficient, which will easily cause the risk of explosion. Zhu Pingan nodded and said slowly.
Zhang Hong listened with a serious look on his face. He couldn't help but be filled with emotion when he heard this. He was greatly inspired and asked quickly, "So there is such a thing as making artillery. No wonder I always thought that artillery was either too heavy. Or it will be easy to explode, and I don’t know what the best balance is.”
“I don’t know how to calculate the specific artillery diameter ratio. I didn’t understand it when I read it, so I can’t remember it. However, I saw a summary in the book, saying that after countless tests, the gun body and The artillery diameter at the muzzle is about 22 times, and its powerful range can reach one It is a relatively ideal value. In addition, it is recorded in one of the latest and most advanced artillery classics of the Ming Dynasty that "the foreigners have a method of calculating proportions. For example, if the caliber of a cannon is one inch, the caliber of the cannon is one inch." It should be one inch thick near the tail, seven and a half centimeters thick near the ears, and five centimeters thick near the mouth. Therefore, from the outside, the cannon has a sharp mouth and a plump tail. The diameter of the ear and the length of the ear are both one inch, and the proportions are mutually beneficial." Zhu Ping'an said with some embarrassment. There was no way he was a liberal arts student. Regarding firearms, these are all things I saw on the Internet out of interest in modern times.
It’s thanks to my good memory that I managed to remember some of it, otherwise I’m afraid it would be even more embarrassing.
"The diameter of the gun body and muzzle is about 22 times, and the power range reaches an ideal value. Sir, does the gun body here refer to the barrel length or the overall gun length?"
Zhang Hong asked for advice.
As expected of someone who secretly learned artillery skills from a red-haired barbarian, this question is a professional one.
"It refers to the length of the barrel." Zhu Pingan thought for a while and made sure that he did not answer wrong.
"Thank you, sir. If the art of doubling the diameter of artillery is correct, it is really an incredible technology. How long is the gun body, how powerful is it, and the geometry of iron and copper required? All the key problems of these artillery can be solved. In the past, when developing artillery, I always felt that the heavier the artillery, the thicker the muzzle, and the thicker the barrel. Thick, the more gunpowder is loaded, the greater the power of the artillery. Therefore, artillery has a thick barrel and a thick muzzle, but the length of the barrel is ignored. No wonder, I always felt that although the artillery was heavier and thicker, it was not powerful. Although it is satisfactory, incidents of barrel explosion often occur. It turns out that the thicker the artillery, the better."
Zhang Hong said excitedly, getting more and more excited as he talked, "This artillery multiplication technology is incredible. No wonder the Hong Mao Yi's artillery is better than ours. No wonder I always feel that the size of the Hong Mao Yi's artillery is a little different." It turns out there is something. At present, my Ming artillery is too bulky and powerful. With limited power, artillery for city defense needs to be powerful, and for sieges and field operations it needs to be flexible and easy to carry. With the art of doubling the diameter of artillery, ordinary people can find a balance between weight and power, reduce the weight of artillery, and increase the effectiveness of artillery. The power will greatly improve city defense artillery and field artillery."
Zhang Hong was excited and ready to work hard to improve the city defense artillery and field artillery.
"Master Zhang, the main enemy at present is the Japanese pirates. I want Master Zhang to help me develop a portable artillery that is suitable for the watery, forested and hilly terrain in the south of the Japanese River and is easy to carry and transport. Although the current Fran cannon is powerful, it is too bulky, the range of the bowl-mouth gun is too short, and its power is also limited. There is an urgent need for a new type of lightweight artillery to combat Japanese pirates.”
Zhu Ping’an saw that Master Zhang was very ambitious and wanted to develop and perfect artillery such as city defense artillery and field artillery. The art of improving artillery cannot be completed overnight, and it cannot be completed in ten or eight years.
Currently, the Japanese pirates have no time to delay. The Japanese invasion is getting worse and worse day by day, and there is not so much time left.
So Zhu Pingan directly pointed out the direction and asked Zhang Hong to develop an artillery suitable for the terrain of Jiangnan.
Instead of wasting time, effort and money on developing a wide variety of artillery, it is better to carefully develop one artillery piece. The south of the Yangtze River is mostly covered with hills, forests, and paddy fields. Bulky city defense artillery and field artillery are not suitable. Only light artillery is suitable.
“I was looking through the classics of Europa and other foreign barbarians in the Hanlin Academy Library, and found that one of the books recorded a sketch of an artillery piece, which was a light artillery being developed by foreign barbarians. In order to facilitate shooting, the artillery was fired assumed a fixed posture , like a tiger squatting, firing at an elevated angle."
Zhu Ping'an briefly described the tiger squatting gun invented by Qi Jiguang in the future, and asked Zhang Hong to improve and develop it using more advanced artillery multiplication techniques. I believe you will not be disappointed.
"Don't worry, sir, the common people will definitely live up to your expectations." Zhang Hong clenched his fists hard, hammered his chest hard, and said loudly. (End of this chapter)
