Chapter 172 Flying
It was late at night and people still didn’t want to sleep. They gathered around the square in the city center and watched the tailors and embroiderers sewing a big thing.
Someone thought that this was related to what was said on the radio in the afternoon about the master marrying a wife, so he asked a tailor he knew: "Are you sewing the wedding dress of the master and his wife?"
The tailor shook his head and answered. : "I don't know, we just know how to work."
After that, he continued to sew a piece of red and a piece of yellow cloth together.
Liebherr came over soon after and carefully checked whether the cloths were sewn with two stitches as required and whether the distance between the stitches was too wide.
Cutting the hot air balloon balloon required a series of calculations in Frederick's opinion. Unexpectedly, it turned out to be very simple for the tailor, who referred to the method of making a hat.
After taking out the model in the carpenter's shop, it is pasted on paper, divided into grids, then peeled off and cut according to the grid, and finally enlarged in proportion to the size of the cloth.
In addition to tailors, many people were mobilized.
A merchant selling cable ropes at the port directly asked his warehouse to be emptied, and he only took a nominal fee so that he could brag about his contribution to the master's marriage in the future.
The large hanging basket under the balloon was very complicated to make. We also found a large and strong rattan basket directly from the port. However, the first rattan basket smelled too much of salted fish, so we later changed it to another.
The workshop that makes tarpaulins moved all the tools directly to the central square, sewn a large piece and processed it immediately.
The busiest thing was the blacksmith shop. Schmidt suddenly had a brain twitch, and then modified an alcohol blowtorch on the spot.
The alcohol blowtorch relies on part of the heat of the conductive flame to vaporize the alcohol and then spray it out. It is fully mixed with the air and burns violently.
So he improved the lamp head, and the pipe passed around the flame. The alcohol inside was fully vaporized and then sprayed out. The pipe was made of copper pipes obtained from the pressure gauge factory.
The fuel barrel that stores alcohol is directly modified from a pressure cooker. A copper pipe is welded to the safety valve of the pot lid and the sealing valve used for the pressure gauge on the steam engine is used to pump air inside. At the pressure valve, the inner end is connected to a pipe that extends into the pot near the bottom of the pot, and the outer end is connected to the main sealing valve and copper pipes leading to the blowtorch matrix.
Before igniting, just use a pump to inflate the pot. When the air pressure is enough, close the pressurized pipe sealing valve, then open the main sealing valve, and the alcohol will be sent to the blowtorch matrix under the action of air pressure. , and you can also adjust the firepower.
The experiment proved that the firepower of this burner is quite strong.
There is also an umbrella valve on the top of the hot air balloon to control the exhaust. It is like an open umbrella. Under the action of the rising hot air, it presses against the top of the balloon from the inside. It is controlled by ropes, pulleys and a rope to control. When you need to vent, just pull the control rope, the edge of the umbrella valve will be separated from the balloon, and the hot air will be discharged. When you need to close it, you only need to loosen the rope, and the hot air will push up the umbrella valve to make it fit with the balloon, and the gas will not leak out.
In addition, Frederick also asked him to prepare a thermometer and a barometer with a special dial. The dial of the barometer can be rotated and the scale is converted into altitude, which can be used as an altitude reference.
When the sun reaches the top of the sky, the hot air balloon is finally ready.
Frederick immediately ordered a test flight and asked for one chicken, one duck and one sheep to be the first passengers.
He asked people to fix one end of the tethering rope at the upper and lower air vents, and then used this as the end point to set the positions of the other two tethering ropes so that the four points formed a square with four corners.
A giant trebuchet has been assembled around the hot air balloon, with heavy objects placed in their weight baskets. A more than ten meter long crossbar is erected high, and the upper part of the balloon is lifted through ropes. Half of it was lifted up and spread open.
After making sure that the fixed ends of the tethering ropes were tied firmly, Frederick got under the ball bag and asked Liebherr to light it.
The alcohol blowtorch matrix sprayed out 16 blue flames more than one meter long, and the hot air quickly filled the inside of the air bag, which became more and more bulging.
After confirming that the alcohol blowtorch matrix was operating normally, Liebherr and Frederick slipped out, leaving a chicken, a duck, and a sheep in the hanging basket.
Not long after the rope on the trebuchet was loosened, the hot air balloon rose into the air.
The hot air balloon rose higher and higher, and was finally caught by the tethering rope about 500 meters above the ground.
After almost ten minutes, the fuel was exhausted, the flame was extinguished, and the hot air balloon slowly fell back to the ground.
Someone quickly ran over, untied the top rope on the burner rack, and then pulled it with several people. The other end of the rope was the top of the air bag to control the direction in which the air bag landed. More people ran over to check whether the air bag and various components were damaged.
The chickens, ducks, and sheep have all been taken out of the hanging baskets, and they are all alive and kicking, so there is no need to delay the extra meal tonight.
Frederick waited quietly on the side until Liebherr came over and then asked anxiously: "How is it, is there anything broken?"
"No." Liebherr replied, "Everything is normal."
At this time, Schmidt also came over and said excitedly: "I think we can hold more fuel and fly longer."
Frederick shook his head and said: "Don't bother me. If you want to be practical in the future, Let’s use a magic circle instead of a burner. Now pack everything up and transport it to the Principality of Mainz overnight.”
The next day, under the noon sun, a fiery red hot air balloon attracted people. The yellow double-headed eagle emblem on the eyeball in the entire hunting camp is particularly conspicuous.
In the hanging basket 500 meters above the ground, the Grand Duke of Mainz said calmly: "Well, this gadget is somewhat interesting, just give it a try."
Bai next to him Grand Duke En sneered and said: "If you have the ability, don't shake your feet when you speak."
The Archduke of Mainz replied: "Don't tremble if you have the ability."
Philip asked Frederick: "How long will it take for us to go down?"
They generally understood the principle of the hot air balloon. , but I didn’t fully understand it. At the same time, I felt that this thing I made in one night was not very reliable. I was very worried that I would fall down after the blue flame above my head went out.
The three people were clinging to the edge of the hanging basket. If they hadn't been wearing gloves, they might have cut their hands on the rattan.
Frederick did not answer. He had only been flying into the sky for less than two minutes, and he continued to throw an apple into the air with all his strength.
I saw a flash of golden light, Dawn swooped down from the sky, bit the apple in the air, chewed it twice before swallowing it, and then hovered around, waiting for the next apple to fly out.
At this time, Frederick rolled his eyes and said: "Let me tell you a joke. There was a bear, a pig and a crow sitting on the hot air balloon. The crow kicked the bear and said, 'You are so stupid!" Go over and give me some room to come out. The pig saw it and kicked the bear to get some space. Then the bear got angry and threw the crow and the pig out of the hanging basket. The crow smiled at the pig. Said, 'Be silly, I can fly.'"
The joke was over, but the three passengers did not laugh, but looked nervously at the flames above their heads.
Frederick smiled and said nothing, just waiting for someone to agree to something.
He quietly reached out to the valve of the alcohol tank and twisted it slightly. After a moment, three people exclaimed from behind him.
"Ah! The fire is going out!!!"
The fire did not recover due to the shouts of the passengers, and even showed signs of slowly weakening. The passengers shouted louder.
Archduke Byrne wiped the cold sweat from his forehead. He was the first to realize what Frederick was doing. He thought to himself why he couldn't hold back his curiosity and waded into the muddy water. If he didn't go down, he might have to go. A few years less to live.
He immediately shouted to Philip and the Archduke of Mainz: "You two, hurry up and agree to Wesson's marriage!"
Two minutes later, the hot air balloon slowly landed on the ground. , the three passengers jumped out before the gondola hit the ground.
Frederick left the basket, walked to Maria, and with a smile on his face, picked up his rosy-cheeked fiancée and spun her around a few times.
Maria lowered her head and punched him, and then asked: "How much will it cost to let the guests go to heaven this time?"
