Great Tang princess

Chapter 282 Parachute Experiment

As for the gondola of the hot air balloon, Li Yuechen's design is the size that can be played by eight people.

There must be two drivers who alternately use the pedals to continuously fill the furnace with air to control the size of the flame.

As for fuel, coal already exists in this era, but it is called coal.

There are many open-pit coal mines in Ruzhou, where some simple coal mining can be done. In the future, it should be called Pingdingshan.

Li Yuechen has already found someone to experiment with this stove. If the speed is controlled well, the size of the flame can be controlled, as long as the two of them alternate.

The only downside is that burning coal produces smoke, which is a bit choking.Therefore, smoke exhaust pipes are added on both sides of the stove, at least not to let the people in the hot air balloon be choked.

Of course, whether it can fly or not, we still have to wait until the production is completed.

The Shangyi Bureau was not idle either. After such a long period of continuous experimentation with the Craftsman, the sewing machine was finally made.

Unlike the sewing machine in Li Yuechen's impression, this one is much bigger.

Generally, the sewing machine is rotated by constantly stepping on the pedal under the foot and driven by a belt.

After continuous experiments by the people at the Shangyi Bureau, it was found that this thing is really easy to use. The speed of making clothes or sewing fabrics is several times faster.

Then Li Yuechen asked them to make some different styles of things to try, such as berets and the like.

This novel invention did not surprise Li Zhi and his wife too much. After all, Li Yuechen had invented too many things. Compared with the utensils that can fly into the sky, these things still feel a little worse.

At most, I think this thing sews clothes very quickly.

Seeing the calm expressions of his parents, Li Yuechen explained: "Mother and Dad, don't underestimate this thing. It's nothing if there is only one machine, but if there are many, the efficiency is quite powerful!"

"It's true. In the future, making some clothes, or sewing and mending, will be much faster." Wu Zetian nodded perfunctorily.

Seeing his parents' attitude, Li Yuechen had no intention of showing off, so he changed the topic.

Recently, the ministers in the court have been quieter, maybe they also know that it is meaningless.

After all, it's not because they don't want the princess to be crown prince, but because the emperor already had such thoughts, but the princess herself refused.

If they continue to do things, it may cause dissatisfaction with the emperor and the princess, so it's better to be quiet recently.

……

In a blink of an eye, it is the end of June, and the production of the hot air balloon is finally completed!

Inside the barracks, the huge hot air balloon has already inflated, and the ascension experiment has begun.

Li Yuechen tried it in a hot air balloon by himself. The rope was connected under the hanging basket to ensure that it would not fly too high. If it could be kept at a height of about six or seven meters above the ground, the experiment would be considered a success.

At this height, even if something unexpected happens, with her ability, she can jump off immediately without any harm.

Several military officers including Geng Yunqiang and everyone from the Academy of Engineering were nearby, looking up at the huge hot air balloon with puzzled expressions on their expressions.

"This thing feels like a large Kongming lantern..." Wang Gangdan murmured slightly to himself.

"This is the difference between His Highness and me and other mortals. Why has no one thought before that the Kongming lantern can carry people to the sky?" A craftsman next to him laughed.

Li Yuechen, who was about to fall into the hanging basket, almost fell over when he heard these words. What he said, you wait for mortals... as if I am not a mortal.

After entering the hanging basket, Li Yuechen sat on a stool in the corner, put his feet on the pedals and began to kick up.

The pedals drive the fan blades, continuously pouring air into the middle furnace, and the air goes all the way up, making the flames burning on it more vigorous.

It didn't take long before I heard Geng Yunqiang outside the gondola shouting: "Get up, get up..."

Others also took a closer look curiously, and found that the hot air balloon had gradually left the ground and began to lift off slowly.

In less than ten seconds, the hot air balloon had risen to a height of six or seven meters, but because it was pulled by the rope, it could not rise again, so it could only stay at this height.

Li Yuechen stopped the pedals slowly, stood up and went to check the surroundings. By the way, he raised his head to see if there was any damage inside the balloon.

After a series of inspections, there was nothing wrong with it, so I pulled the lever under the stove and closed the iron plate at the stove mouth little by little.

The iron plate closed slowly, the flame gradually became smaller, and the hot air balloon began to descend slowly.

The rise and fall of the hot air balloon is controlled by this. The flame is bigger, the height rises, the flame becomes smaller, the temperature drops, and the height naturally drops slowly.

It's just that the direction control of a hot air balloon is much more difficult than that of a hang glider, because it itself does not have the equipment to control the direction.

To achieve this, you only need to constantly adjust the height. The wind direction is different at different heights. If you want to adjust the wind direction, you must use different wind directions at different heights to achieve the purpose of movement.

After Li Yuechen came out of the hanging basket, Geng Yunqiang took two steps towards this side with an excited expression on his face: "Your Highness, did you succeed?"

"Well, it's done." Li Yuechen nodded, then looked at him and smiled slightly: "What? Do you want to try?"

"This... I just think about it again. If the army can equip this thing, it will be very convenient for moving or doing reconnaissance missions in the future..." Geng Yunqiang nodded and said.

"Don't worry, you will use it, but in another way." Li Yuechen explained, "In the future, you will often take this hot air balloon, sneak into the enemy's rear, and carry out missions such as reconnaissance or assassination."

Geng Yunqiang looked puzzled: "But I just observed that this thing takes off and lands very slowly. Didn't we just hit the enemy's ambush when we went down?"

"Who said it's slowly landing? You're going to jump off then!" Li Yuechen said expressionlessly.

As soon as these words came out, not only Geng Yunqiang, but even the people from the engineering academy next to him were completely stunned, and they all turned their heads to look at him with incredulous expressions.

Their expressions were very puzzled, and they all wondered if they had heard it wrong just now.

Geng Yunqiang's brain was in a state of shutdown, what did His Highness just say?Jump from the sky?

"Hehe... Your Highness must be joking, right?"

Li Yuechen raised his head slightly: "What do you think?"

Seeing her expression, Geng Yunqiang froze in place.

As a subordinate, Geng Yunqiang knew Li Yuechen very well, and from the expression on her face, he knew that she wasn't joking at all.

But... if you jump from the sky, won't you fall to your death?
Li Yuechen didn't intend to continue teasing him, but waved his hands and said: "Okay, the experiment will be done next, and I will go to Dali Temple tomorrow to bring a death row prisoner over, and let him finish the decapitated meal by the way. Maybe this experiment will kill."

"Yes!" Geng Yunqiang agreed with a salute.

……

Geng Yunqiang's work efficiency was very high, and after lunch at noon the next day, he brought a death row prisoner who was tied up in a big way.

After the prisoner came over, he kept yelling: "It's not the time yet, I should be executed after autumn! It's not the time yet..."

But Geng Yunqiang didn't care about his shouts, and dragged him all the way to the experimental field of the Engineering Academy.

Looking at the death row prisoner who was tied up by five flowers, Li Yuechen handed the parachute bag in his hand to Geng Yunqiang, asking him to take it with him, and then began to direct the people next to him to light the stove, add coal, and prepare to let the hot air balloon go up into the air .

After the death row prisoner was forcibly put on a parachute bag, he was tied up again.

Li Yuechen told Geng Yunqiang and others beside him: "After flying into the sky for a while, I will throw this person down from the sky..."

Before they finished speaking, Geng Yunqiang and others who heard this sentence looked at the princess in shock.

I've never heard of a princess having this hobby before.

Judging from their expressions, I knew that they didn't think of anything good, but Li Yuechen didn't care, and continued to explain: "If there is no accident, this person will open a big umbrella during the fall. Hongfeng, you and others are ready at any time." , follow him on horseback, and take back this man and the umbrella when the time comes..."

After finishing speaking, regardless of what they thought, they carried the prisoner into the hanging basket, and at the same time arranged two soldiers to step on the pedals beside them.

The two soldiers who were selected were very excited. It was an honor to be selected by His Highness to fly into the sky.

Li Yuechen didn't bother to care about how excited they were, but just asked them to pedal each other's shifts to control the hot air balloon.

After a while, the hot air balloon lifted off slowly, and the altitude began to climb.

The prisoner who was still shouting at the side suddenly became quiet, and looked at the scenery outside the hanging basket with an incredulous expression on his face.

The two soldiers also looked surprised, feeling the completely different scenery in the sky with their hearts.

Li Yuechen was constantly estimating the altitude, licking his fingers from time to time and stretching out to test the wind direction.

Gradually, the hot air balloon got higher and higher, surpassing the imperial city, surpassing the mountains, and finally, it seemed that they faintly surpassed the clouds.

The cloud layer is actually not as high as imagined. The vertical height of the cloud layer closest to the ground may only be about one thousand meters.

However, for the prisoner or the two soldiers, this kind of scene was unimaginable at all, looking at the cloud that was close at hand, one of the soldiers said: "Dare to ask Your Highness, can I get close to that cloud and reach out to grab it? "

"That thing can't be grasped, it's essentially water vapor...or you can understand it as smoke." Li Yuechen explained with a smile, then poked his head out and looked out, feeling that it was almost the same.

So he directly reached out and grabbed the shoulder of the prisoner next to him: "I have asked, the crime you committed is not serious, and it has not reached the point of wrath. If you can survive, you will be exempted from the death penalty!"

This person just got into a fight with someone on the street, then got into a fight, and beat him to death by mistake.

This kind of murder is not considered intentional homicide in the law. If he can cooperate with the experiment well, his death sentence can be pardoned, and it is nothing more than giving more compensation to the family members who were killed.

After finishing speaking, without waiting for any reaction from the other party, Li Yuechen directly lifted him over his head, and then threw the man out of the hanging basket.

Seeing this scene, the two soldiers next to them felt their hearts jumping with fear. If they fell from such a place, they would have been frightened to death before they fell to death, right?

Sure enough, the moment the prisoner was thrown out, he let out a scream, but because the falling speed was too fast, he couldn't hear it soon.

Li Yuechen propped his arms on the edge of the hanging basket and looked down at the scene below, although he couldn't see anything clearly at this height.

There is no need to worry about opening the parachute. The moment Li Yuechen threw it down, he had already opened the guiding parachute. As long as there is no problem with the production of the parachute, he will definitely be able to land safely.

Of course, this peace refers to the body, whether the mind is safe or not is unknown.

……

On the other side, Geng Yunqiang on the ground was leading a company of people in the test field to look at the sky boredly, and raised the telescope to look at the sky from time to time.

It's just that the telescopes of this era may not have a large enough multiple, and Li Yuechen and others have already reached above the clouds, so they can't see anything.

However, after a short time, a soldier suddenly pointed to the sky: "Look, Battalion Commander!"

Geng Yunqiang looked up and saw a large rectangular umbrella suddenly opened from the sky, and there seemed to be a small black dot connected underneath.

The umbrella was being blown by the wind and gradually flew towards the southeast, moving lightly.

"Get on the horse! Chase!"

Seeing this scene, Geng Yunqiang immediately gave the order, and led the soldiers to run wildly, and hurriedly chased after him.

Everyone followed the parachute falling from the sky and ran all the way, and finally caught up with each other after about a cup of tea.

At this time, it happened that the parachute also landed in a place behind Mang Mountain, and Geng Yunqiang and others rushed to check it.

A soldier knelt down and touched the prisoner's neck: "Not dead, passed out."

Being thrown down from the sky, he must have fainted from fright... Geng Yunqiang thought to himself.

At the same time, he also understood what His Highness meant by jumping from the sky just now, and it was obvious that he used the big umbrella on this person to do it.

Since this person survived by jumping from the sky, they should be able to do it after training.

After recovering the parachute and the prisoners, Geng Yunqiang and others quickly returned to the barracks.

At the same time, Li Yuechen also commanded the two soldiers to slowly land, letting the hot air balloon slowly fall into the test field.

Before it landed completely, Li Yuechen jumped out of the basket directly.

"how?"

"Your Highness, it's amazing! He's still alive, but just fainted." Geng Yunqiang replied a little excitedly, "Then I'll wait..."

"You think skydiving is easy?" Li Yuechen turned his head and asked.

"This……"

Looking at his expression, he knew that he underestimated this matter too much. To be honest, Li Yuechen was afraid that such a thing would happen.

Skydiving is a very dangerous thing, if you do it wrong, you will die.

If a person falls from the sky, there is a high probability that he will be smashed into a puddle of pus and blood, and his original appearance will not be seen at all.

Before formal skydiving training, they must be well trained in this aspect of safety knowledge.

They must understand that I spent so much money to train them, not to make them die.
