"Brother Yuanqing"

What happened in the palace, whether it was his brother Li Tai who was going to fly in a hot air balloon, or whether the hot air balloon fell and injured many people, and his brother Li Tai was also injured, these palace maids who had been waiting for a long time told Changle.

Changle, who was lifted from the grounding order, went straight to his brother's Li Tai's dormitory as soon as he was released. It's just that I didn't expect Brother Yuanqing to be there, but Changle, who originally came to comfort the sick number, shouted directly and shouted Brother Yuanqing and threw himself into Wu Yuanqing's arms.

Such an unrestrained and heart-wrenching scene, Li Tai's heart was sour when he watched it. Sister Xiangcheng was arched by Wu Yuanqing, and now my sister is like this again, how can this make the royal love embarrassing.

Could it be that all the men in this world are dead, Li Tai couldn't help but ask himself in his heart.

"Oops"

Li Tai shouted, causing Changle who only had Brother Yuanqing in his eyes to wake up instantly. The little face was flushed with shame, and he hurriedly let go of the little hand holding Wu Yuanqing, and then hurriedly ran to Li Tai's side, and asked worriedly: "Fourth brother, what's wrong with you, is there anything uncomfortable?"

"Uncomfortable? No, I'm not uncomfortable." Li Tai shook his head.

"Then why are you screaming so loudly?" Changle asked.

"Oh, that's it, I can't figure out how to control the rise and fall of the hot air balloon, I'm upset, so I scream and vent." Li Tai made up the reason.

"By the way, brother-in-law, do you have any good solutions?" Li Taichong Wu Yuanqing asked.

Looking at Li Tai's pretending appearance, Wu Yuanqing was angry and funny, this guy rarely calls himself brother-in-law, and now he calls it so in front of Changle, he is definitely burying himself.

"Brother-in-law, you are talking, is there a good way?" Li Tai asked with a smug smile.

"As for the hot air balloon you made, I don't think there is any need to improve, I can redesign it, make an upgraded version, and the problems you encounter can be solved." Wu Yuanqing said with a smile.

"That's not good, on the basis of what I did, you can see if you can solve it?" Li Tai was not happy, didn't Wu Yuanqing deny his invention by saying this, how could this be?

"Oh, well, it's not impossible to improve on your basis, just change the combustion device." Wu Yuanqing said with a smile.

"How can it be improved, you can tell me more specifically." LI Taidao.

Boy, Lao Tzu saved you, you don't say thank you, you even bury Lao Tzu, you wait, Lao Tzu will hit you next from the IQ will not kill you.

Thinking so in his heart, Wu Yuanqing spoke: "It's very simple, the combustion device you made is too bad, just a stove without a lid, it's too dangerous to put it on a hot air balloon, and the fire power is not enough to use pine resin and wood as fuel, so it can be eliminated directly."

"No, how can you eliminate it, how can you heat the air in a hot air balloon without this." Li Tai was in a hurry, this was a solution he came up with after thinking and thinking about it.

"We can use kerosene as fuel, which produces more heat than wood, pine resin, and doesn't leave anything behind, so it's safer. As for how to use the oil, it is good to make a sealed iron bucket, of course, it is better to use copper. Then a curved tube is attached to one end of the barrel, and a spraying device with a rotary closure is added to the tube."

Speaking of this, Wu Yuanqing stopped, sorted out his thoughts and continued: "Then at the other end of the barrel, we also have to add a rotating device, one end of this device is a round iron disc that fits the diameter of the inner wall of the barrel. The iron disc consists of a threaded iron pillar connected to the outer turntable through the bottom opening of the barrel. These openings are then sealed with boiled beef tendon mixed with fish gelatin. It is good to make a gasket, or to pour it directly, anyway, to ensure that the iron bucket is sealed after the lid is closed. Oh, by the way, the iron plate inside is also, the hand-made iron plate must not be able to absolutely fit the inner wall of the barrel directly, not large, otherwise it can't fit in, but it can be a little smaller, and then the same beef tendon and fish glue wrap the iron plate around, the boiled beef tendon is elastic, a little larger than the inner wall of the barrel, and it can also be better sealed."

"It's so troublesome, I'm confused about what you say, what's the use of doing this?" Li Tai listened to it a little foggy, and Changle was even more stupid and cute in the blink of an eye.

Wu Yuanqing is also very helpless, it is really difficult for the uninformed ancients to explain and communicate some things with them, this will be put in the future generations, you tell the children that I want to make something similar to a syringe, and they can also know a rough idea.

At least you can see how the syringe works.

Yes, this barrel made by Wu Yuanqing is similar to a syringe, and the principle is the same.

The inner disc is connected to the outer steering wheel, which is equivalent to the lever of the syringe.

The oil in it is the same as the liquid in the syringe.

Then the tube at the other end is the needle, which is just a needle with the same closure device as a spray faucet.

Fill the barrel with oil, but not full, leave a certain amount of air, and then rotate the disc on the top, turn the disc inward, let the disc in the barrel compress the air, the air is compressed to a certain extent, open the closed valve on the pipe, the compressed air in the barrel will squeeze the oil from the bottom of the barrel through the pipe, the pipe bends at a certain angle and then straight upward, far beyond the height of the barrel, and then hold the fire at the pipe spout and wait, as soon as the oil is sprayed, it will be ignited. Because it is pushed by a huge compressed air, the sprayed oil will go up, and the flame will also rush upward, the height of this channel is determined by the size of the compressed air, and also determined by the closed valve, the larger the valve is opened, the more force the oil is sprayed, the higher the spray, the greater the flame, and the opposite is true when the valve is closed.

In this way, the size of the flame can be controlled at will, and the rise and fall of the hot air balloon can be controlled.

The driver of the hot air balloon only needs to adjust the switch or twist the disc a few times at a certain time to let it continue to maintain enough pressure on the air in the barrel.

The most important thing about this device is the airtightness, although it is difficult to do, but it is not impossible to do, let the craftsmen polish it a little bit, and it will take nothing more than a little more time.

Then another need to solve the problem of hot air balloon fire resistance, with firewood and pine resin is good to say, the flame can not be high, but with fire oil is different, in case it is not controlled to spray on the hot air balloon, the satin pulp is a little bit.

But this is not difficult, just get some asbestos fiber woven cloth and sew it in a circle close to the flame.

This kind of cloth has been recorded in the ancient book "Classic of Mountains and Seas". Because www.biquge.info of its non-flammability and ability to remove dirt in fire, it is often called "fire cloth" or "fire cloth" in early history books.

"Liezi": "King Mu of Zhou conquered Xirong, Xirong offered the sword of Kun, and the cloth of Huohuan. …… The cloth of the fire and the must be thrown into the fire, the cloth is the color of fire, and the color of the dirt is the color of the cloth. ”

In myths and legends, Kunlun Mountain has a total of nine layers, and it is surrounded by a scorching mountain, and in the fire grows a kind of rat that is bigger than a cow, weighing thousands of catties, two feet long, and the capillary is like silk. The rat was red when it lived in the fire, and turned white as soon as it came out, and as soon as it left the fire, he quickly took water and splashed it. If it is dirty, it will be burned in the fire, and it will be as white as new, and people will call it fire cloth. "The Records of the Ten Continents in the Sea", "Foreign Objects", "Fu Zi", "Divine Strange Scriptures" and so on are all recorded.

Fire cloth is very precious, but it is only for other people, and it is easy for the royal family to get a little.

Wu Yuanqing even said with a gesture, and wasted the strength of nine cows and two tigers, and finally let Li Tai understand what kind of device he was talking about.

Then Li Tai was hit hard, and his leg didn't hurt anymore, so he patted his injured head and said why he didn't think about it.

Wu Yuanqing smiled and said nothing, but he was very proud in his heart, this is not only the crushing of IQ, the key is to complete the abuse in knowledge.
