Chapter 1648 Come out, artillery double diameter technology

Seeing that Ou Zhige couldn't wait to study gunpowder, Zhu Ping'an got up and said goodbye empathetically.

Next stop, Zhang Hong.

The same process, the same routine, the same respect for the virtuous and the corporal, the same hush and warmth, and the same homework, and then inadvertently revealed that he used to be in charge of the Hanlin Academy Library Pavilion, which contained hundreds of firearms classics, as well as the latest and most advanced technology developed by the Ming Dynasty. The cutting-edge and most confidential firearms classics, and of course the more than ten firearms classics collected with great care about Europa, Franji, and Red Maoyi.

"More than a dozen firearms classics about Europa, Franji, and Hongmaoyi?! Are there artillery?"

As soon as he heard that there were more than ten foreign firearms classics such as Europa, Franji, and Red Maoyi in the library of the Hanlin Academy, Zhang Hong's hand holding the teacup couldn't help shaking, and the tea was swung out. Weaker than Ouzhige.

He was a person who once went to Nanyang to steal Hongyi artillery. After a period of time in Nanyang, he knew that although Hongyi and others were barbarians and did not know etiquette, their firecrackers and artillery were far ahead of Ming Dynasty.

"Of course there is. There is also a book dedicated to the study of a cannon called the Frang Machine Cannon. It is recorded in the book that 'the bullets of the blunderbuss fall like rain, and they are invincible. The cannon is cast in copper. It's called the Frang Cannon'. I'm very interested in the Frang Cannon. Before the Flang Cannon, my Daming artillery had to be front-loaded with gunpowder, and it couldn't be fired continuously. The actual use is quite limited, and the Franc machine gun has sub-guns. When firing, the sub-guns filled with gunpowder are loaded into the mother gun. After firing, the sub-guns are discarded and withdrawn, and another sub-gun can be fired. Replacement, greatly increasing the firing speed, is of great benefit in actual combat. Oh, there is also a book that records a cannon called Hongyi Cannon, which is more than two feet long and weighs two to three thousand catties. .

Zhu Ping'an replied without hesitation, and at the end he mentioned the Hongyi Cannon.

After listening to Zhu Ping'an's words, Zhang Hong was so excited that he couldn't help himself. Zhu Pingan's description of the Flang machine artillery was completely correct, and when he stole the Hongmaoyi artillery in Nanyang, he once saw it on the bow of the Hongmaoyi ship. The "Hongyi Cannon" described by Zhu Pingan once, although he didn't know that the cannon was called Hongyi Cannon at the time, but the three-foot-long cannon left a deep impression on him at that time. There are classics about foreign artillery such as Europa and Hongmaoyi.

In order to improve his artillery skills, he was able to leave his hometown, hang out in Nanyang, and learn how to make artillery from Hong Maoyi.

Although he racked his brains and tried his best to learn a lot of skills from the Hongmaoyi, but after all, he was stealing the teacher, and without the comprehensive guidance of the Hongmaoyi, he still did not learn the skills of firearms such as the Frang machine gun.

If he had to evaluate it by himself, he probably only learned about 50% of it. The Frang machine gun he imitated was far inferior to the real Frang machine gun made by Hong Maoyi, which made him very unwilling.

Now I heard that there are more than ten books about foreign firearms such as Europa and Hongmaoyi in the Library of the Hanlin Academy. How can I not be excited.

"Although it is a bit abrupt, I don't know if adults can study these classics at that time, but now they can still remember the contents."

Zhang Hong asked excitedly.

Zhu Pingan told Zhang Hong again what he said to Ou Zhige, because I had a good memory, I had a lot of time at that time, I read it several times, and I still remembered about 70% to 80% of the content.

"My lord, please teach me about foreign artillery. I, Zhang Hong, have only your lord to follow in my life. If you have something to say, I dare not refuse."

Zhang Hong, like Ou Zhige, knelt down excitedly, expressed his loyalty to Zhu Pingan, and asked Zhu Pingan for advice.

The reason why Zhang Hong, like Ou Zhige, both knelt down to show their loyalty, or because they came from humble backgrounds and had no wealth, so they had to sell their bodies for refuge, which was the only bargaining chip they could have.

"Craftsman Zhang is serious, please hurry up, Master Zhang is my craftsman in the Zhejiang Army, so I naturally know everything I can say."

Zhu Pingan helped Zhang Hong up, and told Zhang Hong what he had said to Ou Zhige again, to reassure him.

"Please enlighten me, my lord, I, Zhang, will definitely live up to your expectations." Zhang Hong clasped his fists seriously.

"I've read a lot about artillery, and it's been a long time, so I'm a little confused, so let's talk about it. I will come to discuss with Master Zhang often in the future. It must be two The rear sight is installed on the side, which can assist aiming and increase the hit rate, Master Zhang must be aware of it."

Zhu Pingan took a sip of tea and said slowly.

"Yes, Hongmaoyi is whimsical, adding a rear sight to the gun body, which greatly improves the hit rate. I have never had this device in the artillery. It can be used as a reference for other artillery in order to increase the hit rate."

Zhang Hong nodded vigorously and replied.

"Yes, some ideas of Hongmaoyi are still of great reference value. For example, he added a steel hoop to the gun body, which is like a barrel to hoop the gun body. According to his book, it can effectively imitate the blasting of the artillery."

Zhu Pingan gave another example.

"Oh, it makes sense, you can add steel hoops to prevent the artillery from exploding. Although it can't be 100% prevented, it can definitely greatly reduce the artillery explosion." After hearing this, Zhang Hong was deeply inspired and nodded repeatedly.

"About the Frang Machine Cannon, I have also researched the latest and most cutting-edge artillery classics of the Ming Dynasty. Regarding the Flang Machine Cannon, our Daming Capital Military Bureau has also tested it many times, and made innovations. Several practical results have been obtained. Specifically I can't remember very well, but I only remember three points. The first is that the child gun must fit closely to the mother gun; The door, the front sight and the target are connected in a straight line; the third is more practical, and a wooden handle is added to the gun for easy loading, unloading and fixing."

Zhu Ping'an continued.

"I have also noticed that the sub-gun fits the mother blunderbuss. Three points and one line, the addition of a wooden handle to the sub-gun is worthy of the capital's military strategy, and it really lives up to its reputation." Zhang Hong said with a look of admiration, and he was deeply inspired.

"About the Folang machine gun, I won't say more about adding lugs to the gun body to transfer these superficial truths. There is one point I want to talk to Master Zhang." Zhu Ping'an's tone became serious.

"My lord, please teach me." Zhang Hong cupped his fists and bowed deeply.

"Many of the more than ten firearms classics written by Europa, Franji, etc., mentioned the double diameter technology of artillery, saying that it is one of the fundamental principles of artillery, and the production of artillery must follow this technology." Zhu Ping'an said with a look on his face. Said solemnly.

"Cannon double diameter technology? The fundamental principle of artillery, which must be followed when making artillery?"

It was the first time in Zhang Hong's life that he heard the word 'cannon double diameter', and he opened his mouth wide in surprise, as if he had heard a heavenly book.
