Bai Erwa flew up, flying under the power of four horses.
Unfortunately, the flexibility, stability, and maneuverability are far inferior to what Li Yuanxing brought from later generations. This is the gap in craftsmanship. Li Yuanxing approached Li Changying: "Changying, I congratulate you. Such achievements are very impressive.
.I am very satisfied, but you must also take good care of yourself, you have lost weight these days!"
Li Yuanxing's few words of praise and comforting words almost brought tears to Li Changying's eyes.
Li Yuanxing patted the back of Li Changying's hand twice, then picked up the telescope and set it up to watch Bai Erwa fly. In fact, Li Yuanxing was communicating in the time machine at this time.
"Is there any result?" Li Yuanxing asked the time machine.
"If the time difference is four times, there must be other items produced. But according to this steam engine, it has been proved that the four times necessary relationship." The time machine gave a positive answer.
Li Yuanxing asked again: "I have always suspected that these are all in movies or animations."
"Your conjecture is wrong. It can be achieved theoretically. But in your era, just because there are more efficient ways, steam engines can only be used in a single direction of mechanical kinetic energy. If such a steam cannon,
In our time, we can make it even more sophisticated, and the air pressure can reach more than sixty pascals. But the one we see in front of us is only about fifteen pascals."
Li Yuanxing seemed to understand: "I think Yaozhou should be researching steam turbines, the pinnacle product of steam power!"
The time machine did not answer, seemingly acquiescing to Li Yuanxing's guess.
"Additional question! Which is theoretically more difficult to manufacture, artillery or steam cannon?"
"Artillery!" After the time machine gave an explanation, he stopped expressing his opinion. Why artillery is more difficult is something that Li Yuanxing needs to learn and research by himself.
Li Yuanxing put down the telescope, and Bai Erwa had already flown back.
"I need a detailed report about this cannon!" Li Yuanxing put the telescope on the small table nearby.
It was not Li Changying's task to hand in the report. She leaned next to Li Yuanxing: "Your Highness, several alchemy masters originally planned to use the gunpowder used in fireworks to make cannons. Unfortunately, after loading the iron bullets, they could not even fly a hundred steps.
Although the amount of gunpowder was large, the barrel of the gun was blown open and the iron bullet did not fly out."
"Yes!" Li Yuanxing nodded.
Although Li Yuanxing did not go to college, even if he went to college, he might not be able to learn similar majors. Real knowledge still comes from a lot of reading.
Li Changying originally said that Li Yuanxing could understand that the strength of the gun barrel was a problem. Now what is being made is gunpowder, not explosives. There is a qualitative difference. It is still possible to put a Vulcan Flying Crow, but to truly turn it into an artillery, explosives are needed, and
Explosives of sufficient purity are needed.
"Your Highness, this cannon is inspired by that little snack tool!"
"Small snacks?" Li Yuanxing couldn't think of any snack-making items that could be turned into cannons.
"It's popcorn!"
Popcorn!
Li Yuanxing laughed, that thing is really powerful. I remember when I was a child, the long iron ball was burned on the stove, and then the strong air pressure turned the corn kernels into popcorn. The last moment it was opened, there was a loud bang, which was very powerful.
.
But what about increasing this power tenfold?
Li Yuanxing thought of this and motioned to bring a cannonball to take a look.
The guards brought three cannonballs. The shapes of the three cannonballs were almost the same. The most interesting thing was that each cannonball had three rings.
"Your Highness, the first one is a wooden ring, the second one is a rubber ring, and the third one is an oil ring." A personal guard brought three more rings.
Li Yuanxing nodded and motioned to his guards to continue speaking.
These three rings, to put it simply, increase air tightness, increase lubrication, and reduce friction with the barrel.
"Your Highness, the first iron bullet is a solid bullet, with a pointed iron bullet in the front and a lead shell in the back. The second iron bullet is a hollow bullet with a phosphorus warhead at the front, gunpowder and some small ones inside.
Iron nails. The third one is also a hollow bullet, filled with kerosene, and also uses phosphorus to ignite the front end of the warhead!"
“Go try it!”
Li Yuanxing played with the air guns of later generations. Ordinary air guns are loaded with lead bullets the size of mung beans. It is very useful to shoot a bird or something at a distance of 70 or 80 meters. The lethality is not small. Even if it hits a rabbit, it only needs to be hit.
If it hits the vital point, the rabbit will not die or be seriously injured.
However, if you hit him on the leg or something, the rabbit will still run away.
Later high-pressure air guns could hit about 200 meters, with an effective range of about 120 meters.
At the moment, I don't know how far this air pressure cannon can hit.
The guards opened the back cover and started loading ammunition.
Li Yuanxing sat and watched from a distance. This was a rear-mounted type, and it obviously used a flange. Then six iron buckles were added to fasten the flange. Four rubber rings were used for sealing, and then the flange was connected.
Pressurized cylinders.
This cylinder is twice as long and about four times thicker than the one used to make popcorn.
The cylinder is not directly connected to the gun body, but is placed on a rack and then connected through a flange.
"Your Highness, this cylinder can be fired four times in a row!" Li Changying explained softly to Li Yuanxing from the side.
Li Yuanxing remembered reading in a book that the prototype of an air gun existed in Europe in the fourteenth century. Then it was equipped with the army in the seventeenth century, and there were also gas bottles that could fire lead bullets twenty times.
But that's an air rifle, this is an air cannon.
"Write it down and let them study it. Put the entire bottle of gas at once to explode and increase the intensity. This is a cannon. It must have range and power. If it is made small, then continuous shooting will still have some fun!" Li Yuanxing said
, there was a guard nearby who took a pen and paper and quickly wrote it down.
Bai Erwa has landed, her face full of excitement.
"Since Erba, you like flying so much, I allow you to recruit one hundred soldiers, one in a hundred." Li Yuanxing said calmly.
"Thank you, Your Highness!" Bai Erwa bowed heavily and stepped aside.
Li Yuanxing closed his eyes slightly, waiting for the air cannon to be fired. Finally, all the guards left the air cannon and stood on one side, bowing and waiting for orders. Li Yuanxing raised the fan in his hand slightly, and then waved it down fiercely.
"Let go!" the guard in charge shouted, and then another guard pulled the gun door hard.
Dare to test the cannon in front of Li Yuanxing, that is, after many tests, he has enough confidence. Otherwise, Li Changying would not have rushed back to Qin Wangzhuang overnight, so there is absolutely no possibility of failure.
There was a muffled sound, and Li Yuanxing felt the ground beneath his feet shaking.
The eight-foot-long cannon barrel was still trembling slightly, and a hundred feet away, a dozen bamboo rafts were already placed there.
I didn't even notice what happened, as the bamboo rafts were smashed to pieces.
"Maximum range?" Li Yuanxing asked.
"Your Highness, I haven't tested it because there is not enough space in Yaozhou. When I tested the cannon, I accidentally destroyed a workshop and injured several people. I originally wanted to test the cannon in the field, but all the fields were blown up.
Money!" Li Changying already knew about the soap, so naturally he was unwilling to destroy the fields.
"Maximum lethality?" Li Yuanxing asked again.
Li Changying was very nervous: "Your Highness, it still hasn't been tested!"
"Okay, don't be nervous. You can rest for two days and then conduct a comprehensive evaluation. I guess you are eager to let me see this cannon. I know your thoughts!" Li Yuanxing was very gentle, which really moved Li Changying.
After reaching out to help Li Changying up, Li Yuanxing said to Bai Erwa: "First, fill up the gas bottle. I want to know how many days it can be stored. Second, recruit the Chang'anxi Camp and ask the Security Department of the Tang Empire to arrange guarding for three days."
After the cannon test, I want to know all the data. Third, send people to Yaozhou, I want to know the power of this small steam engine. Fourth, block the news!"
After Li Yuanxing said that, he turned around and left.
After walking a few steps, he stopped: "Fifth, you guys have a good rest today, but keep an eye on things!"
"Yes!" Bai Erwa bowed and obeyed the order.
After sending Li Changying back to the backyard and saying a few words of comfort beside Li Changying's bed, Li Yuanxing returned to the study.
In the study, Wu Zhao is sorting out all the information from this year and listing it in detailed tables, preparing to make a very detailed analysis.
"I need you to go to Yaozhou in person. This time it will take a long time, at least a month."
Wu Zhao was stunned for a moment: "Did something happen in Yaozhou?"
"Yaozhou has made a pneumatic gun. The principle is similar to that of an air gun. However, they have also made two air guns. I will test them in three days, so you need to go to Yaozhou in person. Don't be anxious this time and look at the problem carefully.
Already."
Wu Zhao stood up, walked to Li Yuanxing, and gently took Li Yuanxing's hand: "This time, I will only watch and promise not to say anything."
"It's not that serious. You can consider teaching some basic mathematics, physics, and chemistry knowledge. You make up your mind!"
Wu Zhao seemed to have some hesitation.
"Aren't you afraid that I will cause some trouble for you again?"
"No!" Li Yuanxing shook his head.
Squatting on the ground, he said to Wu Zhao: "The women of Li Yuanxing are not just beautiful vases, nor are they the yes-men of Li Yuanxing. They should have independent thoughts. Take Chunlan and Lan Qiu with you. My only suggestion is to first
Observe and don’t jump to conclusions!”
Wu Zhao's originally depressed expression was swept away: "I'm still very good!"
"That's right, otherwise I wouldn't worry about anyone going to Yaozhou. And I can't leave now!" Li Yuanxing praised him without any hesitation.
"I'm excellent!"
"I know." After Li Yuanxing nodded, he said to Chunlan who was standing aside: "Take good care of Princess Mingyue in Yaozhou, and I will reward you when you come back!" (To be continued. Please search Piaotian Literature for better updates of the novel.
