Chapter 296: The Wind Direction Problem
What A Yuan was depicting was the oldest popcorn machine. She had been squatting in front of the old man in her previous life for too long, and the parts of the machine were so clear in her mind.
Big belly hoist, head screw, big elbow, small elbow, cover, afterburner, afterburner, afterburner, opening pin and handshake. In addition, in order to be able to be mounted on the furnace fire, two front and rear brackets are also required.
The old popcorn machine is actually a pressure vessel. The raw materials for processing are usually corn, rice, broad beans, yellow rice and other common grains. Add some sugar or a few saccharin, put it into the machine, and cover the cover. Use the afterburner and
The loading tube is used together to pressurize the cover by rotating the head screw to facilitate sealing.
Then put the popcorn rack on the bracket and heat it under a strong fire. At the same time, turn the popcorn machine by shaking hands to make the raw materials inside the machine evenly heat and soften.
Due to heat, the pressure in the machine slowly increases. When the required pressure is reached, stop heating, twist the popcorn machine to one side, and cover the port with a sack. Put the assertion tube on the small elbow and turn it with force
The small elbow loosens the buckle between the large elbow, so that under the action of the internal pressure, the hood is opened, and the high-temperature and high-pressure gas in the machine is sprayed out together with the processing raw materials. During the injection process, due to the external pressure
The rapid decline caused the internal gas of the grain to expand outward, and the grain was exploded.
You also have to design a sturdy mask, which will cause bad luck if the person is injured during the test.
Then draw a thick cotton five-finger glove sewing picture. It must be large and can be used on the stove.
To make rice balls in memory, you also need to boil sugar juice and stick to it. You can ignore it for the time being.
Now, A Yuan can't help but go to find a blacksmith to make popcorn machine. In this era, thanks to the founding emperor, he has long had a good thing like corn, which is more fragrant than rice and even more out.
Count it!
Three or two children were sitting in the cinema, holding a large container in one hand and throwing a big smell of popcorn into their mouths with the other. They stared at the screen and could also push their feet on the back of the front seats, if
Good luck, no one is in front of you, and you can even occasionally stick your legs to the seat and sway with your back, leaning on it with a slanted back, which is a different experience!
He called Manager Xu in and arranged for him to find a blacksmith, and specifically told him to prepare the protective mask before trying.
Manager Xu then described the process of accepting "Mobaozhai". Grand Secretary Han was really generous, or he didn't even think about taking away the valuable things in the shop, and there were a lot of papers of various types left. Even Dongba
Six pieces of paper were left.
"Princess. The store is good, but the area is too small. The two rooms are empty. If you can't arrange big business and business, you can't do paper shops. The people you are targeting are wrong. Do you think?"
I was originally a good old manager who was a slut in the princess's house. Now, when it comes to doing business, it is a lot of things. In fact, the old guy is not busy at home, and now he likes to use his brain to make money.
"We'll go take a walk together in the afternoon. Now you will explain the drawings clearly, and then you will have to go to Lord Han's mansion to give away two hundred taels of silver. I'll say that we can ask for the shop for nothing.
Those papers must be paid, otherwise I will not be able to sleep well." As A Yuan said, she laughed again. She rushed to deliver the shop, but she scratched her whole body. She had to give the money to be considered as peace of mind.
Manager Xu took the order and left. The princess was in high spirits and was embarrassed to say that the general account of the princess's mansion was almost exhausted, and the surplus of Zhuyang County was invested in the brick kiln factory and paving roads in Qiyang County, and the capital city
The brick kiln factory and off-season vegetables have changed hands again, but the farm has been left behind, and it is impossible to kill chickens and get eggs to cause trouble. The newly drawn fields have not been officially taken over yet, and it is impossible to have a future in this season if you take over them. Currently, there is only cake.
The two-wheeled vehicles made by the house and the iron and wood shop are profitable. The big ships in Hangzhou Bay only eat and don’t vomit every day, and no sound can be heard when thrown in!
The tricycle is very difficult to sell, so the princess has to think of a way.
On the way, I met the idle and moldy old John. I heard that Manager Xu was going to the ironworks workshop and insisted on following him to see him. Anyway, it was within the Princess's Mansion and it was not considered a violation of the rules.
However, the princess's talent cannot be stolen by foreigners, and the drawings are not for John to show. The blacksmiths are even more stingy, and the parts of the two-wheeler are reluctant to let John move.
The poor man was very angry and ran to A Yuan to complain: "I don't want to learn some crafts secretly. I'm too idle, I feel uncomfortable!"
The most spiritual thing is to direct the construction of the ice rink. He is valued and trusted and has a place for heroes to be useful. He feels that the air in the princess's mansion is fresh.
"You can bear it anymore. The ship is almost built. There is a trial and repair. When Jack and the others set off, they will come back. I guess, the emperor will believe in your sincerity and your free life will begin!"
A Yuan stood up and spoke without a pain in his waist, and he pointed Old John into endless waiting.
As it turns out, men will also have a mental breakdown when they are locked up. Old John began to jump high: "Don't dream! People who have not left the sea don't understand at all. If Jack follows your instructions, he may not be able to walk for a year.
Back home!”
"What are you kidding? We have now developed a compass compass. The big ship is stronger than the one you used to do, why can't you get there?" A Yuan was anxious. If you don't bring this, cursing that his ideal cannot be realized.
No conscience!
Old John laughed strangely: "You can help me find something that can pass the time, and you also want to persuade the emperor to give me freedom earlier, so I will tell you why--"
That's not simple? There are so many jobs available at home!
A Yuan patted the table: "The ironwork workshop is not suitable for you. If you don't have any effort, it is not safe to splash Mars. I allow you to be an apprentice in the woodwork workshop. You can learn whatever you want, and you can harm the wood. When you meet the emperor, you will be the only one.
It’s not impossible to say a few good things."
Old John turned his eyes a few times, his figure retreated, reached the door, stepped out with one foot, and said, "Go back to us, the wind is wrong now, the wind on the sea is regular, it will take half a year to blow, it is best
, wait for the second half of the year to consider-".
The wind direction is wrong? At this time, shipbuilding technology restricts it. It can only be done by manual paddling. If you go along the wind and master the direction, then there is no problem. If it is against the wind, hundreds of sailors will not be far away even if they are exhausted.
The glory of ancient Chinese navigation history depends on the progress of ancient Chinese navigation science and technology. In the Tang Dynasty, the "Sea Island Calculation" has methods to measure the height and distance of sea terrain and land objects, which have a profound impact on the subsequent surveying and mapping of navigation charts.
The first time in the world to use a compass to navigate the sea was in the first year of Xuanhe in the Northern Song Dynasty, that is, in 1119 AD. In the book "Pingzhou Ketan", it was recorded: "The boat master knows geography, and when he is at night, he is at day.
The sun is dark and shady compass.”
Now, there is only one name left in the Song Dynasty that is exactly the same as in history. During the reign of the founding emperor, he also worked hard to instill new scientific knowledge in all walks of life. The current era is still in 1088 AD, the compass
It has been used decades ahead of schedule.
In fact, at this time, the Song Dynasty not only solved the problem of direction, but also made innovations in the rudder technology. For example, many holes were opened on the rudder blade to reduce the resistance to water. The West did not adopt this kind of "hole opening until the century.
Rudder” cargo ship.
Also, the mast was used under the mast to adjust the angle of the sail to cater to the wind direction. The masts of the sea ships that were driven by Old John and his group, who thought that the most advanced technology could not move.
The balancing rudder is used at the stern, and part of the rudder surface is distributed in front of the rudder column to shorten the distance between the rudder pressure center and the rudder shaft, making it more lightweight and flexible to operate.
The hull had rows of nail caps exposed outside, which showed that the "nail joints and mortise" technique was used during shipbuilding. Old John's ship was just tied with leather strips and ropes.
It should be said that this time, the construction of the merchant ship also occupies the light of the princess' identity, so that many advanced equipment of the official ships and warships were borrowed.
In addition, A Yuan once couldn't sleep at night and repeatedly recalled how the cabin leaked and then died in the "Titanic". The cabin design was personally operated: using partitions to divide the cabin into several unconnected spaces, once the cabin is
Water leakage is only partially affected and will not sink the entire ship.
After making such sufficient preparations, now you tell me that the wind direction is wrong? Ah Yuan stood up and stomped his feet violently. Old John knew that it was not good, so he immediately ran away.
This guy did it on purpose!
But I was too messy! I just thought about building the boat well and taking the road with Jack and the others. I didn’t even think about the direction of the wind.
In junior high school, I talked about the issue of monsoon. Since the continent and oceans increase heat and cool down in different degrees during the year, the wind direction changes regularly with the season is called monsoon.
.The phenomenon of opposite wind directions prevailing in a large-scale winter and summer cycle with a one-year cycle.
The day when spring is warm and flowers blooming is just right, and the warm and humid southeast monsoon is coming.
A Yuan squatted on the ground, grabbed a carbon rod and started to draw a world map. Is it really the wind direction wrong?
Starting from Hangzhou Bay, the nearest route should be to go southwest, cross the Strait of Malacca, enter the Indian Ocean from the Pacific Ocean, then cross the Red Sea, the Suez Canal, enter the Mediterranean Sea, and then pass through the Strait of Gibraltar, like north, you can land safely on England Island
It's right.
The inscrutable people are walking eastwards against the wind!
The sailing career is still blank. Old John and the others actually drifted to the Song Dynasty. It is really magical. It is even more rare that they didn't know where they were and where they started. Now they still rely on their sailing experience to make fun of themselves.
, I can draw a complete world map with my hand. Can you? I haven't seen it before? (To be continued. If you like this work, you are welcome to vote for recommendations, monthly votes, and your support is
