She Song

Chapter 271 Parachute and Airship
March passed by in a flash, and the city of Yanjing entered the season of growth for all things.

In Tsinghua University, Dong Xiaowan once again boarded the hot air balloon. This time, she no longer simply tested the lift-off height, but had to do two other tests, namely the parachute and the flight control system.

The person who tested the parachute was Han Wenxiu, and the assistant was her brother Han Ping.

The concept of a parachute originates from the idea of ​​flying a hot air balloon. The current record for a hot air balloon being lifted into the sky is 150 feet, which can avoid attacks by all projectile weapons. However, because of this height, once the hot air balloon loses control or is damaged, the people riding on it will be at risk. No chance of survival.

Seeing that Dong Xiaowan was like a warrior saying goodbye every time he boarded the hot air balloon, Han Xiaoyao couldn't bear it and came up with the concept of parachute.

Making a parachute is actually not complicated, with a thin silk canopy, extremely flexible braided rope, zipper straps and some small parts.

Unexpectedly, Han Wenxiu insisted on joining the parachute development team and asked for personal experiments.

At first no one took it seriously, but it turns out that there are very few people who dare to take the risk of leaping in the air. After Han Ping heard about this, he was very worried about his sister's safety. He tried to persuade his sister to give up several times and could get money from other projects. to honor.

Han Wenxiu rejected his brother's suggestion and said: "I am not doing it for the medal, I just want to prove that I can do something well. If I shrink back because of timidity this time, what if I encounter other difficulties in the future? I will definitely Gotta give it a try!”

Although Han Ping was worried, he finally agreed and proposed that he be an assistant to help his sister complete the development and testing of the parachute.

The Engineering Academy gathered the best craftsmen and talents, and produced the first parachute as required in less than three days. After training and testing on fixed landings of two feet, three feet, and five feet, the structure and functionality of the parachute became more and more perfect.

Gradually, Han Ping also understood the resistance and buoyancy of the air. He knew every part of the parachute and every rope by heart, and became Han Wenxiu's most trusted and effective assistant.

Since Yanjing couldn't find a building higher than [-] feet high, Han Wenxiu took advantage of the opportunity of a hot air balloon to hover in the air, tied a safety rope and did repeated tests from [-] feet to [-] feet, and he was able to Skillfully use the parachute.

Today, Han Wenxiu made a bold decision to parachute directly from a height of fifty feet without tying a safety rope, achieving the first real parachute landing.

Dong Xiaowan skillfully raised the spindle-shaped hot air balloon into the air and said with a smile: "The height is high enough, Wenxiu, are you sure you don't want to tie a safety rope?"

Han Wenxiu had already prepared the parachute bag. After checking it carefully, he nodded: "Always tying the safety rope will lose the meaning of the parachute. After so many experiments, I believe there will be no problem."

Han Ping rechecked for his sister again, and after confirming that everything met the requirements, he said, "I wish you all the best!"

Han Wenxiu smiled brightly, pulled the cable of the hot air balloon and stood at the edge of the pod.

Overlooking the land, Yanjing City has a panoramic view, just like a picture scroll. The Liao Palace is green and grassy, ​​and the Tsinghua Garden is rippling with blue waves and crowded with people.

They were all looking up with telescopes, and seemed to see Han Wenxiu hanging outside the cabin, exclaiming in surprise.

Fuss!
Han Wenxiu turned to his brother and Dong Xiaowan and smiled: "We'll see you on the ground!"

Taking a deep breath, Han Wenxiu opened his arms and flew out of the pod, like a white crane spreading its wings in mid-air. At this moment, everyone on the ground was shocked by Han Wenxiu's courage.

Not tying a safety rope means a desperate fight. A girl is actually more like a warrior who looks at death than most men.

"One, two!"

After silently reciting two numbers, Han Wenxiu, feeling his body falling rapidly, suddenly pulled open the umbrella buckle.

"Shua~huhuhu"

When the familiar sound of opening an umbrella came, Han Wenxiu felt her waist and shoulders tense, as if being held by an invisible hand, and the scene that was like lightning was frozen suddenly.

She raised her head, and the colorful umbrella above her head really looked like a blooming flower.Han Xiaoyao put down the telescope and nodded with a smile. This little girl has a lot to learn, and she also likes to take risks. She is a bit like a mad scientist.

Of course, Han Xiaoyao and Dong Xiaowan also quietly made second-hand preparations. The launch location of the hot air balloon was chosen to be close to the artificial lake. Dong Xiaowan hovered above the center of the lake. This was done to consider that in case of problems with the parachute, the lake water energy could be used to launch the balloon. Effectively slow down the impact of landing.

So, Han Wenxiu, who was full of joy, was finally picked up wet by the cruise ship. Amidst a series of congratulations and praises from everyone, she hurried to the bathroom to change.

After the parachute was successful, Dong Xiaowan began to test the flight control. The wind was southeasterly this season, and the wind force at a height of [-] feet was around level [-], which was just within the preset range.

With the cooperation of Han Ping, Dong Xiaowan pulled off the two cloth covers directly under the spindle-shaped balloon, revealing the two large propellers. Under the influence of the wind, the hot-air balloon officially transformed into an "airship".

The hand-cranked propeller can generate additional propulsion power, just like a waterwheel driving a millstone. Dong Xiaowan and Han Ping began to shake the handle to inject more thrust into the airship.

Under the gaze of the people of Tsinghua Garden and Yanjing City, the airship in the sky slowly moved towards the north of the city, and it was obvious that the speed was not slow.

Dong Xiaowan verified the accuracy of the accelerated flight and recorded the corresponding data and experimental instructions in a timely manner. This is first-hand information and is crucial for future improvements. It is not an exaggeration to say that they are worth a fortune.

After a quarter of an hour, Han Ping's hands felt weak and he could only stop and let the propeller propel the airship to fly under the natural wind.

Looking into the distance for a moment, he looked at the vast world and couldn't help sighing: "It's unbelievable that we, as mortals, can swim freely between the world!"

Dong Xiaowan stopped writing and remembered someone's words, and said: "If we just keep flying over those wild tribes, do you think they will regard us as gods?"

Han Ping turned around suddenly. He never expected that the woman in front of him actually wanted to be a god?
But having said that, many Jurchen tribes and grassland tribes believe that all things are animistic. Flowers, trees, mountains, rivers and lakes are gods, not to mention "airships" that can fly in the sky.

"Xueshi Dong said this...does he want to be a god?"

Dong Xiaowan shook her head and said: "This is what I heard. The original words probably said: People who can use technology beyond the times are no different from gods!"

Han Ping couldn't accept this absurd statement for a while, and retorted: "It can't be compared like this, the magic power of the gods is omnipotent, and mortals will never be able to do it..."

Dong Xiaowan put down the experimental notes and started to debate with the other party.

"Chang'e's flight to the moon is a myth, right? What if one day mortals can also go to the moon?"

"If the airship is powerful enough, it will be possible to fly thousands of miles in one day. Is it considered a miracle?"

Han Ping was not good at arguing, so he was no match for the unruly Dong Xueshi. After a few questions, Han Ping, who didn't know how to answer, immediately admitted defeat.

After flying for two hours, Dong Xiaowan landed near Wangfu Villa in the northern suburbs, and was picked up by the Tsinghua Academy scholars who followed all the way.

Once the airship experiment was successful, the Yanyun Army discovered its huge strategic value.

Think about it, no matter day or night, an airship above your head is enough to scare the enemy, regardless of whether it drops the explosive package or not.

Buy and buy!
The wealthy military ordered five airships at once.Naturally, the first air force unit of the Zhenguo Army was prepared.

Han Xiaoyao couldn't help shaking his head, after one year, the sea, land and air are complete!
