Chapter 156 Congreve

After failing for a long time, people will begin to doubt themselves.

This is true of a person, and it is also true of a country.

There is only one way to break this mentality, and that is to win, win, and win.

Zhu Youzhen knew that this kind of rocket artillery, which was later called Congreve, was actually our own invention in the Central Plains, but it was later spread to Europe and was widely used throughout Southeast Asia.

The first to suffer from this thing were the British, and the rocket artillery imitated by India from the Central Plains inflicted huge casualties on the British who came from afar. After the end of the war, the British shipped the captured rocket artillery back to England, and soon after, announced that their own Royal Woolwich Arsenal had invented Congreve rocket artillery.

Then two hundred years later, at the Bali Bridge, this rocket artillery called Congreve exploded on the heads of the Chinese elite cavalry, causing China two hundred years later to suffer a big loss in the two opium wars.

This kind of thing is not only far away, but also powerful, and will definitely cause great damage to the army in a dense formation. In fact, the most suitable for the current Ming army is specially used to deal with the iron cavalry of the Manchurians like an iron stream.

However, in order to ensure the direction and stability of the rocket's flight, they added a four- or five-meter-long guide rod to the rocket more than one meter long, making the whole rocket a huge monkey.

By the way, it's actually an enlarged version of the monkey that I played when I was a kid.

Zhu Youzhen also said this version when he drew a picture of Sun Yuanhua, but reminded them that they could actually consider the flight mode of the feather arrow.

After the continuous research and restructuring of the Academy of Sciences, Sun Yuanhua and Daming craftsmen, a group of three-piece triangular tail was directly added to the tail of the missile body, but how to fix the tail and how to ensure the strength became the biggest problem. This is also the reason why Sun Yuanhua and the others have not made progress for a long time.

But today, they took this as a surprise to their own emperor.

When he walked into the test site closer to the foot of the mountain, the Jinyi guards, including the emperor's side, rechecked their identities.

The first thing they saw was the rocket launcher, which was actually nine iron barrels with two open ends tightly clamped together, forming a square shape.

Then two horsemen came in with a mule, and behind the mule was a two-wheeled flatbed.

"Your Majesty, please see."

One of the people next to Sun Yuanhua picked up a set of wheels from the table, and at the core was a set of thick iron bearings.

"Everything else is easier to solve, but the difficulty is this kind of iron ball." Looking at Zhu Youzhen's surprised expression, Sun Yuanhua hurriedly added. Handedly handed an iron bead to Zhu Youzhen.

Start with the cold and cool one. "In fact, the difficulty is us, but the master easily solves it. The forging master here directly cut off the rough blank iron, put it in the mold of the iron ball, and manually forged it, and now it can complete 50 to 100 pieces a day. ”

"The most important thing this time is to solve the technology of carburizing and quenching."

As he spoke, Sun Yuanhua pushed out an old craftsman behind him who was covered in fireworks. He was dressed neatly, dressed in a military factory-made labor uniform, with thickened pads on his knees, elbows, and shoulders, but even so, the overalls on his body were burned out, large and small.

Zhu Youzhen didn't wait for the old man to speak first, and asked directly:

"Why are you still not wearing enough overalls and gloves a month?"

The old craftsman didn't dare to speak much, but Sun Yuanhua was anxious. He tugged at the sleeve of the old craftsman, am I easy, I, don't you hurry up and reply to Your Majesty.

"Enough to wear, enough to wear." The old craftsman probably knew who was across from him, and sweat flowed down his cheeks when he said the four words.

"There are many children in the family......

Okay, Zhu Youzhen waved his hand, as long as he knew that the factory would issue tooling on time and in quantity. As for the fact that people are willing to give their own clothes to their sons in the family, what can be said about this? He was in the original time and space, and when he was a child, who hadn't worn the clothes in his parents' factory.

"I know. Protection must be in place, and getting injured is no fun. Tell me, how do you get carbon into the iron balls and turntables? ”

Speaking of which, the old craftsman regains his self-confidence as a master craftsman.

"The villain puts the ball in the earthen pot, and then buries the iron beads in charcoal powder and adds some ......"

"Don't talk about the details, you know what you added, Master Sun knows, I don't need to know."

"Oh." The old craftsman honestly agreed.

"Then put coke on the bottom of the tank and the top of the tank, burn it for two hours, and then decorate the carburizer with a sieve, and quickly pour the red-hot steel balls into the cold water, and it's done!"

"Good!"

Zhu Youzhen couldn't help but applaud, another problem was solved like this.

Then, two groups of people ran into the field. A group lifted the rocket launcher onto the mule cart and secured it with iron pins. Another group lifted another launch vehicle onto a flatbed cart, this time without mules, only five non-commissioned officers waiting to pull the cart.

"Your Majesty, long-distance transportation is enough with a mule, and it is enough to transport a small squad of soldiers in close proximity."

After speaking, the officer on duty at the test site next to him blew the whistle, and the two groups of people began to simulate the movement of rocket launchers around the test site.

"Let go of a cannon and open the eyes of Inspector Sun, General Qin and I."

"Yes, Your Majesty!" Sun Yuanhua hurriedly agreed, and then waved his hand to the officer on duty not far away.

Hearing the command, the red pennant in the flag bearer's hand fell, and the green pennant waved. A horse-drawn carriage transporting a launch vehicle, and two wagons transporting rockets quickly moved to the predetermined launch position in the field.

"Your Majesty, please go down the protective tunnel."

Zhu Youzhen did not refuse, it would be better to listen to persuasion at this time. The group of them went down to the pit not far away, and the pit was not very deep, and they probably arrived at the position of Zhu Youzhen's chest. Then several stacks of sandbags were piled up on the edge of the tunnel.

With another whistle, the whole drill began.

The first is the process of untying the horse. The four men held the back carriage, and the two untied the horses and mules from the carriage from both sides. This one-by-one process is a lesson in blood. At the earliest, in order to ensure firing on the move, they did not even unload their horses. As a result, after the cannon fired, the horses were frightened, pulled the launcher and began to gallop, and also trampled on a number of onlookers.

The two men quickly dismantled the horses from the wheels. Then one person is responsible for arranging the harness used by the horses, and the other moves the horses to the rear. The remaining four men began to fasten the gun carriage to the ground with semicircular iron clasps and spikes.

After the rocket artillery car is fixed. Holding the rules invented by Sun Yuanhua, one began to observe the distance behind the rocket battery, visually inspect the shelling area, and according to the actual distance, asked the remaining two people to adjust the bearing, pitch and swing angle of the entire artillery truck.

Zhu Youzhen did not interrupt, he knew that this kind of measurement was not very critical now, and the rocket artillery relied on indiscriminate floor washing. But for veteran gunners, it may be more accurate to measure it.

Then a long wooden box was moved by the auxiliaries to the back of the gun carriage. The leader of the firing team took out a dagger and violently dismantled the wooden box, and took out the rockets that were more than one meter long and arm thick.

"Your Majesty, please look."

The distance of the rocket is relatively far, and Zhu Youzhen can only look at the model lake and lake. At this time, Sun Yuanhua arranged for the soldiers to carry a rocket into the tunnel.

The rocket artillery shimmered with celadon light in direct sunlight.

"The delta wing thought about a lot of materials and installation methods, and finally we fixed the three delta wings on this copper ring first, and then waited for the launcher to assemble it on the back of the celadon shell."

"One of the reasons for this is that it is easier to install and easier to transport. In addition, after ignition, the copper ring expands rapidly, and the forward impact of the cannonball also makes the delta wing more stable. ”

Later this rocket reached a surprising distance of five thousand meters. Now it's also good, and it can reach a distance of two kilometers steadily. The rocket shells themselves are mainly ceramic, and this process is better than the current forged steel materials. And the cost is the lowest, the cost is low, not to mention that the power of the explosion is greater than that of the general subway shell. Aside from the need to be a little careful when transporting, there are basically no drawbacks.

For the current science and technology of the Ming Dynasty, there is no difficulty at all for porcelain craftsmen to make porcelain that the emperor likes.
