"The cooked copper is the original cabinet, with four legs at the bottom and four copper pipes at the top. A pump is always placed on the pipe and is connected to the oil tank... The range is six meters..."
A long passage roughly means that this thing that can continuously spit out fire is made of wrought copper... and is named Fierce Fire Oil Cabinet.
Yes, the strange pattern in the memorial is the fire oil cabinet that Chongzhen is looking for this time, and it is also the prototype of the burner.
Looking at the records of the fire-breathing oil tank, Chongzhen was shocked. This was a powerful weapon for defending the city.
Not only can it defend the city, but it is also top-notch in naval combat. Which ship can withstand such fierce fire? It is estimated that it can ignite the opponent's ship in an instant.
The most important thing is that in the late Song Dynasty, a copper gourd was developed that could be used by individual soldiers instead of oil tanks. It was incredible.
If there is such a thing in Ningyuan City, as long as there is enough oil, even without firearms, it will be extremely difficult for Jiannu to break through.
"What a bunch of losers. Why don't we use such a good weapon?"
"This thing is mounted on a chariot. No matter how powerful Jiannu's cavalry is, it's just a pile of barbecue!"
"No, you have to use it. Although it will harm Tianhe, you will die as a Taoist friend rather than a poor Taoist!"
After Chongzhen muttered to himself twice, he set his sights on the Menghuo oil cabinet.
There is no rush to re-activate the fierce fire oil tank. He is mainly looking for this thing for another purpose. According to records, this thing can adjust the size of the flame. With a few adjustments, it can be used as a natural hot air balloon burner.
But this fuel needs to be changed. It would be too wasteful to directly burn oil, and the thermal efficiency of oil is too low. If the flame is extinguished when adjusting the size, the problem will be serious.
He remembered that petroleum is a polymer of various compounds that can be distilled at different boiling points to produce gasoline, diesel, and more.
We don't have those advanced technologies and containers of later generations, but we can try the traditional method of distilling liquor. Only God knows whether it will work or not. Anyway, he only knows this one way.
At this point, the three major components needed for the entire hot air balloon have been sorted out, and the oil department has also paid tribute. The warehouse of the Ministry of Industry has a lot of storage, and the only thing missing is the Menghuo oil tank.
If there is a ready-made one, the next time is to experiment with it.
If not, it doesn’t matter. There are clear records and it is not difficult for a skilled craftsman to copy one.
Chongzhen was a man of action. He would do whatever came to his mind, deploying people, preparing materials, venues, etc.
In the following days, in addition to going to morning court every other day and handling government affairs before noon, Chongzhen also took the bank supervisor, bank supervisor, dyeing and weaving bureau, needlework bureau and people transferred from the Ministry of Industry and the Firearms Research Institute in the afternoon. The craftsmen were tinkering in the warrior camp.
On this day, during the morning court, the emperor was restless. The ministers' reports were directly handed over to the cabinet for processing. After the morning court, they left in a hurry.
The emperor was so abnormal that the six cabinet ministers were very puzzled.
"Sir, what's going on with your majesty recently? Why can't you see anyone this afternoon?"
"It seems that we are studying something. A few days ago, we transferred several craftsmen from our Ministry of Industry and Firearms Research Institute, and asked me to prepare a lot of supplies!"
"Research something? What can your Majesty study?"
"Have you forgotten? Flintlock mines, flintlocks, iron-moulded cannons, granulated gunpowder, etc., are all proposed by His Majesty. Now why don't you study them yourself?"
"Mr. Ge, firearms are too dangerous. As the king of a country, what should you do if you are injured?"
"It doesn't matter. Your Majesty has more sense of proportion than anyone else. His Majesty has been tight-lipped since he took the throne. No matter how experienced he is in dealing with things, he is still a young man under the age of twenty. It doesn't matter if he likes to mess around.
I have told Cao Bianjiao to stay close to His Majesty at all times, and his safety will be no problem. "
"Yes, after His Majesty ascended the throne, he toured the northwest, went to Longjing Pass, and personally conquered the grasslands. This year, he went to South Zhili for three months.
Every time there are people, it’s hard to stay in the palace now, let’s take the opportunity to rest for a few days! "
…
Six cabinet ministers gathered in Wenyuan Pavilion and chatted quietly, but they were more curious about what made the emperor so obsessed.
If the emperor had not gone to court early and summoned ministers to deal with government affairs, they would have thought that the emperor was going to follow the path of Xizong again.
In a corner of the Warrior Camp, Chongzhen looked at the objects on the ground, his eyes full of excitement. After working for nearly half a month, all the objects for the hot air balloon were completed, and now it was almost a hit.
"Everyone, start assembling it as I told you before!"
"yes!"
A dozen craftsmen began to assemble it in an orderly manner. The variant of the Kongming Lantern was extremely simple for them.
The tung oil fabric used for the balloon is specially woven by the dyeing and weaving bureau and soaked in medicinal liquid. The tung oil on the outside and the paint on the inside are soft, strong, airtight, and the key is that it is very light.
The entire balloon is 150 square meters and weighs less than 30 pounds. It was also used to make a sky lantern before, proving that it can fly.
The hanging basket is made of rattan armor. It is two meters long, wide and one meter high, but it weighs less than fifty kilograms.
The heaviest thing is the burner converted from a fierce oil fire cabinet, which weighs almost a hundred pounds.
The fuel is distilled from petroleum. After many experiments, he actually distilled some liquid.
According to his judgment, it was definitely not gasoline, but it was extremely flammable and had a strong fire, which was enough for Chongzhen.
After calculation, the weight of the entire hot air balloon is about 250 kilograms, which is much lower than expected.
"Your Majesty, the assembly has been completed!"
Two quarters of an hour later, the head craftsman in charge of assembly reported to Chongzhen, waking up Chongzhen who was wandering in the sky.
Looking at the prepared hot air balloon, Chongzhen took a deep breath and took the fire seal from the craftsman's hand: "Everyone, the next step is to witness the miracle. If successful, your names will be written in the annals of history. "
After saying that, he lit the burner, and the flame burst out, shooting more than half a meter high. Along with the thick smoke, a heat wave hit.
Feeling the overwhelming heat wave and looking at the rising flames, Cao Bianjiao's eyes were full of fear.
After distilling this thing a few days ago, some craftsmen were curious about what it was. As a result, the liquid was instantly ignited and could not be quenched by water. If the emperor had not reminded it to be covered with soil, the consequences would have been disastrous.
"Your Majesty, please move back!"
Chongzhen nodded and stepped back more than ten meters. He watched the ball bag bulge a little, slowly rose up, and dragged the basket nearly one meter above the ground.
Without waiting for Chongzhen's instructions, the craftsman who operated the burner quickly adjusted the knob of the burner to reduce the flame and let the hot air balloon hang still.
