Chapter 354 Must be stronger than the barbarians!

On the artillery range of the craftsman camp on the west bank of the Baihe River in the north of Yunzhou Fort, Shi Tiegen, Li Chengmao and others were looking at Zhang Cheng in doubt, especially Li Chengmao repeatedly muttered: "Wooden pipe... wooden support..."

He also picked up a cylindrical cannon and checked it. Suddenly, Li Chengmao jumped up and said in surprise: "The commander-in-chief said, use a wooden tube instead of a reed tube as a fuze...?"

Now even Shi Tiegen looked at Zhang Cheng with surprise on his face, the meaning was obvious, Marshal, how did you think of it, can the wooden pipe really replace the reed pipe?

In their puzzled eyes, Zhang Cheng smiled calmly and said: "I also remembered for a while, I seemed to have heard some old master talk about this matter a while ago, but today I suddenly remembered, but I don't know many details, but I still have to It's up to you to figure it out on your own."

He looked at Li Chengmao, and continued: "Li Chengmao, since you are the head of the Artillery Bureau, I will tell you some thoughts in my heart, and you come and think about it together."

Zhang Cheng raised his hand, pointed to the cylindrical cannon held in his left hand, and said, "You see, this cannon is controlled entirely by the fuze, and the length of the fuze controls the time when the cannon explodes.
Now we are using a reed tube, the tube wall is thin and flammable, and it is natural, the value of each reed tube is not uniform, you can try to use a wooden tube as a fuze,
As for what kind of wood to use, I can't say here. You can try all kinds of wood. Take a piece of dry wood, drill and grind it into an empty tube in the center, and compact it with granules of black gunpowder.

As for how thick the wooden tube should be, more experiments are needed. Initially, it can be made longer. If it is successful, it can be considered to pre-fabricate the wooden tube in three lengths, corresponding to the commonly used shooting angles. "

Li Chengmao replied: "The villain has written it all down. And the wooden support that the commander just said is...?"

Zhang Cheng smiled. Fortunately, I usually read a lot of things on the Internet. Although the details are not clear, but the direction is always right, this is enough. As for the specific technical details, they can be handed over to these craftsmen.

He didn't say anything about Mutuo, but he called Lin Fangping and ordered: "Fangping, send an order that dinner is served here, so Chi Yuan needn't wait."

"Here!"

Lin Fangping received the order and arranged to go to Yunzhou to report and guard Chiyuan.

Here, Zhang Cheng turned his head and said to Li Chengmao and Shi Tiegen: "The cannon barrel and the cannon can't be completely closed, when firing, there must be fire, if there is too much, the cannon will burst, or the fuse will burn quickly.

You see, if a wooden bottom bracket is fixed at the end of the cannon, and one or two horizontal grooves are carved on the wooden bracket, it can effectively reduce the overflow of fire and gas.
The fire gas just ignites the wooden fuze, and the wooden support is plugged in the barrel, which also helps to increase the chamber pressure in the barrel and increase the rate of fire. At the same time, the gun has such a tail, which is head-heavy and tail-light, which is also conducive to stabilizing the flight trajectory.

Of course, this is just an idea. How to design and operate it depends on you masters to study it. You can follow this idea to improve the gun regulation of this flying cannon. "

"Yes, the villain has written it all down!"

"Well, come on, ask someone to shoot two shots to see the effect!"

Following the passing of the military order, six sergeants trotted forward. They were in groups of three. One of them held the flying cannon to fix the position, the other put the cannon into the barrel, and the third took the torch in his hand and lit it. fuze.

Two clouds of smoke rose, and cylindrical cannons flew out of the smoke. They first flew high into the sky, drawing a beautiful arc, and the two cannons landed at a distance of 150 steps and [-] steps respectively.

One of them exploded when it hit the ground. Iron filings could be seen flying around, and a cloud of smoke rose instantly, while the other one, which landed at a distance of 150 steps, exploded after a short while after landing. open.

Although there are still many unsatisfactory things, but as a mortar in this era, Zhang Cheng is still satisfied. He just asked Li Chengmao to say:
"The effect of this flying cannon is still good, and the manufacturing process is not difficult. First prepare a hundred pieces, but the shells used in it need to be carefully considered. Try the wooden support and wooden tube fuze I proposed."

When Zhang Cheng said this, he suddenly turned his head and said to Shi Tiegen, "Shi Tiegen, send someone to tell the chiefs of the Gunpowder Bureau Wang Gancheng, the Gunpowder Bureau Du Gui, the Vehicle Frame Bureau Xin Congjian, and the Armor Bureau. Share dinner with you."

"Yes, the villain will make arrangements now, Commander, shall we take a look at other places?" Shi Tiegen asked.

"Don't read it, find a clean place, I'll chat with you, and wait for dinner." Zhang Cheng ordered.

…………

In Shenshi, Yunzhou Carpenter Camp was in a village fort near the Baihe River. There was a small building by the riverside. Although it was only two stories high, it was the tallest in the village fort because it was built on an earthen platform. building.

Zhang Cheng was looking at the Baihe River outside by the window on the second floor of this small building. Wei Zhice walked over slowly and said softly beside Zhang Cheng: "Commander, Chen Zhong accompanied Jin Yong over a few days ago, and since the end of the Take away ten heavy carriages and one hundred chariot soldiers.

Was it true that the commander-in-chief ordered Jin Yong and others to attack Muzhajian Zhao Shihu? "

"Hehe, it's just a trick to attack Guo!"

"False way to attack Guo?"

"Haha, don't worry too much, you will know in the future."

Zhang Cheng smiled mysteriously at Wei Zhice, turned around and walked back into the room. Everyone was talking softly, but they all stopped when they saw Zhang Cheng turning around and walking.

Zhang Cheng sat down in his seat, and said with a smile: "You wait to continue chatting, in fact, I really like the topic you waited for just now, is it about artillery?"

When he came over, several people here had stopped discussing, but Zhang Cheng still heard something vaguely, and Li Chengmao bowed and replied: "Back to the commander, the villain and others are indeed talking about artillery, it's about sub-medicine Burning and fuzing problems."

"Oh."

Zhang Cheng is now very interested in firearms. Of course, he is also very clear that the current level of firearm technology is not enough to determine the success or failure of the war.

But if they are well-made, well-trained, strictly disciplined, use firearms reasonably, and cooperate closely with infantry and cavalry, although they cannot determine the success or failure of a war, they can still play a very critical role in the outcome of a battle.

He also doesn't expect that he can bring a breakthrough to the firearms technology of the late Ming Dynasty, but as long as he can set a correct direction for them and give them a correct goal, he believes that the performance of the skilled craftsmen of the Ming Dynasty will not be weaker than that of the European powers of later generations.

At that moment, he said solemnly: "The use of this firearm is full of knowledge. You must be good at summarizing in order to make continuous progress. Let's just talk about this bird gun. We didn't learn it from the barbarians.

Even the elder Xu Ge at the time of the apocalypse advocated imitating the Westerners. Aren't the Hongyi cannons and Flang machine guns all brought by the barbarians and Flang machines?

Okay, let's learn, there is nothing wrong with this book, but we can't always learn from others, if we lag behind in learning, we will be beaten if we lag behind, we have to study and ponder by ourselves, we must be better than barbarians! "
