"Master Wang."
"Is Master Wang here?"
“…”
In the middle of the night, hundreds of people showed up at a blacksmith shop near Dafengtai with suspicious eyes.
Master Wang had worked closely with the Kyushu Academy of Sciences before, and the steam engine was built by Master Wang.
When Master Wang opened the door with sleepy eyes, he was shocked to see hundreds of people standing at the door. He looked at Liu Jinghong and others in the lead: "You, why are you here?"
"Can we go in and talk."
Liu Jinghong looked around with a guilty conscience.
"Quick, come in quickly, alas, it's freezing cold here, come in quickly."
Master Wang gave way and hundreds of people filed into the courtyard. No one noticed that at the dark street corner, there was a young man wearing a plush cotton robe, and the man who looked like an iron tower standing next to the young man.
"Li Zhen, what are they doing?"
Li Zhen took off the fox fur hat, blew the dust on the plush, and said with a half-smile, "It must be something big."
"Aren't you going to stop it?"
"Well, I used to take the lead in making things happen. How can I stop it? Can it be stopped? They are all a group of people who are not afraid of death."
“…”
In the courtyard, when Master Wang saw the drawings drawn by Liu Jinghong and others, he felt a little stupid: "This... what is this?"
On the drawing, a strange object is described in pencil. The whole body is made of tarpaulin, which looks like a parachute, but it is not round. But a long and flat shape.
It is about ten meters long and two meters wide. The two ends are arc-shaped and double-layered, connected in the middle by a tarpaulin of the same material.
Paragliding!
Who knows how Liu Jinghong came up with this thing? After thinking about it for three days, he finally figured out what a paraglider would look like.
"Master Wang, don't worry about what this is for now. We have to work in your yard. Although you are a blacksmith, you must have some insights into handicrafts, right? If you are not good at it, it doesn't matter. We just lend you this place. Use it, we’ll do it ourselves.”
Master Wang nodded: "If you need any help, you can tell me."
"Well, it's not convenient for us to show up yet. We also asked Master Wang to buy some oilcloth for us, as well as pins and nylon thread..."
After Liu Jinghong shared the materials, he gave Master Wang money, and Master Wang immediately took his apprentice out to purchase.
After Master Wang left, everyone sat cross-legged in the courtyard and began to discuss.
"If I guess correctly, based on aerodynamics and experiments in flow mechanics, the paraglider designed this time can achieve a gliding effect."
"Brother Jinghong, what's wrong with your brain? Can you imagine this?"
"No, I just made guesses and assumptions. This is what a bird's wings look like. Most of the time a bird can fly into the sky because of the force in the air. And we can't make anything that can imitate flapping wings, so This can be verified with this parachute made to imitate wings.”
"Well, this really makes sense. Both parachutes have proven that using wind resistance can definitely slow down the speed of free fall. So on the basis of this parachute, add forward, left and right The facility to control the direction makes it really possible to glide.”
Liu Jinghong got a large glass fish tank and filled it with water: "Let's conduct such an experiment first."
"We compare the water in this water tank to air. We compare the resistance in the water to the resistance of air. In this way, we can conduct experiments first."
“…”
While Master Wang went out to buy materials, everyone sat together and cut out a model of a paraglider from cloth.
A stone is tied to the paraglider model with a rope.
The piece of cloth in the shape of a paraglider replaced the paraglider. Stones replace people. The stone can produce a falling force, but the piece of cloth can produce an upward force. Once the two forces are balanced and placed in water, the purpose is achieved.
"According to this dynamics, the tilt angle of the paraglider needs to be adjusted. Because the cloth is soft, we can use different lengths of ropes to achieve the tilt angle... "
When Liu Jinghong had everything ready, Lin Xiufeng said, "I bet that the stone and cloth will move downward at an oblique angle during the sinking process. That is, there will be forward force."
"Haha, we'll see."
“…”
When Liu Jinghong let go, sure enough, the stone was covered with cloth and slowly sank in the water. At first it just sank, but as the weight of the stone straightened the rope, the piece of cloth tightened instantly, and then began to slowly move forward and downward.
"The theory and experiments are successful. We just need to wait for the physical objects to appear and personal verification."
Liu Jinghong looked at the fish tank excitedly.
Everyone was also inexplicably excited.
"When the speed of descent is controllable, we actually only need a forward force to achieve the meaning of flight."
"No, it's gliding."
“…”
Master Wang quickly bought the materials, and then under the leadership of Liu Jinghong, everyone lit up the lamps, sat in the yard and started sewing.
"Let's go faster."
"Try to finish the experiment before dawn."
"Master Li will know as the delay grows longer."
"Come on, let's all come together."
"The stitching of the oilcloth must be tight. This is a matter of life and death. When it is torn in the air, the fun will be greater."
"Just in case, let's get another parachute out, shall we?"
“…”
When Master Wang found out that this group of people had made this device and were about to jump off the cliff, he was scared out of his mind.
"No, no, it's too dangerous. Does Master Li know? No, I have to tell Master Li."
Liu Jinghong stared: "Tie them up!"
Master Wang and several of his disciples were no match for these hundreds of people. They were tied up and gagged after three strikes.
"Uuuuuuuuuuuuuuuuu"
Master Wang was so anxious that he kept trying to howl, but he could only make a whining sound.
Qin Enze said with a smile: "I'm sorry for you first. We'll come back and untie it for you after we finish the experiment."
"Uuuuuuuuuuuuuuu" Master Wang kept struggling, he was really anxious. These people are simply unreasonable lunatics.
In about two hours, with the concerted efforts of hundreds of people, the paraglider was ready.
"Let's go."
"It's almost dawn. Hurry, go to the nameless cliff by the sea."
"Let's test the flight on Wuming Cliff. It's right on the sea. Even if it fails, we can still fall into the sea to save our lives."
"Go quickly, go quickly."
“…”
A group of people urged, carrying the quickly made paragliders, and swarmed towards the unknown cliff on the seaside.
Not long after they left, Li Zhen walked out from the corner: "I'll follow them. Qi Lengzi, go and untie Master Wang."
"knew."
“…”
Looking at the people in front of him who disappeared in a flash, Li Zhen felt a little tired: "I didn't even know the principle yet, so I started experimenting. Alas."
