Lin Yueru and Xiao Niangpi both clamored to do the experiment, but Yang Fan refused.
Are you kidding me? There is danger in the ship trial. If it capsizes, these two landlubbers will definitely have to go down to save it. The river water in this season and the temperature make me tremble just thinking about it.
But I couldn't stand their coquettish behavior, so I had to let them get on the boat.
Yang Fan was sitting on a Grand Master's chair in the middle of the boat. Lin Yueru and Tu Shanyue were fighting each other. They squeezed half their butts in each other, squeezing Yang Fan so hard. He looked around and neither of them had any intention of getting up. He sighed and had no choice but to
That’s it.
"Master, how do we get there?" Mo Zui asked as helmsman.
Yang Fan decided to sail downstream first. Zhang Goda and Donkey Dan were on the left and right, and Mo was the strongest and he was at the back. At the front were two strong soldiers.
"Start downstream." Yang Fan ordered.
Five bicycles drive five small propellers to rotate rapidly.
The boat rocked a little crookedly and left the river bank and headed towards the middle of the river.
"Slow down, slow down for me. What about you, Donkey Dan? Pay attention to your coordination, slow down first and then go fast." Yang Fan said loudly.
The boat began to move forward at a slow speed, and the five people tried to match the speed of others. This power distribution arrangement, if one side is fast, will cause it to turn or even spin in the center of the river.
However, the five people soon mastered the skills. This human-powered device is really easy to use. It is much faster than rowing a boat.
Not tired yet.
After all, stepping with your feet and using your arms are not the same concept at all.
The boat is like an arrow,
Speeding along the current quickly,
The bow of the ship stirred up splashing waves,
Everyone's clothes were wet.
Mei Xiang was so frightened that she started screaming.
However, Lin Yueru and Xiao Niangpi were very excited, their little faces turned red with excitement,
He kept shouting, "Hurry up, hurry up."
This speed has exceeded the fastest horse speed.
"master,
You are so great, I like you so much." Lin Yueru's eyes were full of little stars. She hugged Yang Fan and kissed him hard on the left cheek.
The angry little girl gave her a dissatisfied look.
Although Yang Fan and Lin Yueru had a crush on each other before getting married, after all, they were not in a serious relationship with their young lady. They were typical people who got married first and then fell in love.
Judging from the current situation, Yang Fan and Lin Yueru are getting along well, and their relationship is getting warmer. After all, they play poker every day.
After a long time, feelings will develop even if there is no emotion.
In Lin Yueru’s view,
Since marrying into the Yang family,
Whether it’s food,
The things she used and enjoyed were things she had never seen in her life. Girls would become corrupted very quickly.
Now she feels that she can no longer live in the Yang family.
I also started to have a little admiration for Yang Fan in my heart.
Yang Fan is so amazing that he can actually invent such a powerful method of propulsion.
A student in a sailing class in an academy used wooden blocks to measure speed while running back and forth on the boat.
"Master, the maximum speed is fifteen knots." He looked at the data table carefully, "This should be the maximum speed that can be achieved with no load downstream."
Yang Fan nodded. There were many people on this small boat. Although there was no cargo,
But running with this speed is still very impressive.
"Turn around and go back."
"Here"
The two people on the left immediately slowed down and the boat turned around smoothly.
Once you turn around, you are swimming against the current.
The speed suddenly dropped, and the boat stopped for a moment. Then as the five people exerted their strength,
Start driving slowly upstream.
This proves this human power,
It is possible to travel upstream while carrying passengers.
"Boost,
See how many knots you can run," Yang Fan ordered.
"Here!"
The five people gradually accelerated,
The boat was getting faster and faster, and soon the speed reached five knots.
Several people pedaled desperately, increasing their strength to the limit. The speed of the boat reached 7.5 knots and then it could not get on.
Gu Yan soon replaced the exhausted Donkey Dan and the others with five people, and continued to drive back.
In the end, Yang Fan found that it was most suitable to stabilize at five knots.
"master,
This ship is narrow and has low resistance, so it is fast. If the length-to-width ratio is three to one, the estimated speed of a cannon ship is only three knots." Song Yingxing said.
Hearing that Yang Fan was going to experiment with a new ship propulsion method, Song Yingxing rushed over anxiously. He had an obsessive love for all science and technology.
"It's enough to reach three knots, which is 5.5 kilometers in one hour. There is a 500-mile waterway from here to Bashang Grassland. It is estimated that it will take four days and four nights. The return trip down the river will probably take two days or even one day.
That's it." Yang Fan was already very satisfied. With this speed in this era, he could completely consolidate the territory outside the Great Wall.
Everyone went up to try it one after another, and enjoyed it to the fullest.
In the evening, Yang Fan took his wives back to the tent, all exhausted and sweating.
Looking at the cat-legged bathtub that had been installed, Yang Fan decided to take a bath.
Yang Fan discovered that the most prodigal was not his wives, but his Yao Guang.
What a spendthrift, the cat-legged bathtub is too expensive.
Behind the big tent, on the floor to the east is a large bed newly made of birch wood. After all, there were many people, so the bed was too small and too crowded. It was difficult to sleep well.
A large cat-legged bathtub is installed on the west side. It is a modern product transmitted from Yaoguang. It can be used by five or six people.
The bathtub and bed are separated by a screen made of gauze.
Yang Fan was lying on the big birch bed, where he could watch the hibiscus coming out of the water through the gauze screen.
In order to fill the bathtub with enough hot water, several rows of solar water heaters are used outside.
At this time, Yang Fan was taking a hot bath with his wives.
There is also a plastic big yellow duck floating on the water.
It was being pushed and played by Lin Yueru. This was the first time for Lin Yueru to see such a cute duck.
The little girl was full of thoughts and had a lot of fun.
She has been hiding from time to time since she was a child.
She has been wandering around in her childhood, and she lacks the childhood that others have.
Therefore, marrying Yang Fan, a warm man, made up for the shortcoming in her heart.
There is also a clipper ship model with a double-decker gun store floating on the water. Yang Fanzheng and Xiao Niangpi carefully explained the various functions of this ship.
This boat is,
The next battleship to be built by Beitangkou Shipyard is a sailing battleship with a displacement of about 900 tons and a double-decker gun warehouse.
There are twenty guns on each side,
There is also a rotating heavy cannon at the front and end, for a total of forty-two cannons.
This firepower is enough to crush the Dutch, Spanish, Portuguese, British and French warships in India.
The speed is more than doubled.
For seaworthiness and stability, the length-to-width ratio of this ship was enlarged to six to one, making it look thicker and fatter. The speed was around 13 knots, twice that of Western warships of this era. The artillery used Xinghe iron
Open hearth steel casting plant.
The weight is much lighter than that of bronze cannons. Because the steel is of high quality and the tube wall is thinner, it can be cast larger.
Yang Fan's gunpowder is better. The maroon powder burns stably and has good linearity. The barrel is stronger and can be loaded with more gunpowder.
Yang Fan increased the diameter to thirty-six times.
In other words, the length of the barrel is thirty-six times the caliber, which is already a very powerful level.
Cannons used by the navy, the larger the diameter, the farther the range.
Lin Yueru played duck for a while and then came closer to look at Yang Fan's battleship model.
Yang Fan hugged Xiao Niangpi with one hand and Lin Yueru with the other, and said: "After we got married, we haven't gone on vacation yet. When this boat is built, I will take you to Jeju Island for vacation. There will be a castle overlooking the sea and built inside.
Another big villa.”
Xiao Niangpi and Lin Yueru became happy when they heard that their husband took them out to play.
Yang Fan looked at his battleship model, pushed it with his hand, and watched it rippling on the water. Thinking of the king crab and abalone porridge in Jeju Island, he couldn't help but swallow his saliva.
Alas! I really want to try it one day.
