Deep in the valley of Bachimen are the rows of factories of the Keelung Machinery Factory, which have been built into the military base of the crossing team.

The door of the airship hangar was wide open, and a huge silver-white airship was pulled out of the garage by the soldiers of the Air Force Ground Support Squadron.

The huge airship was round, like a squished rugby. In order to reduce wind resistance on the sides, the cross-section of the airship was designed to be oval, and a few small wings grew on the tail, which was to increase maneuverability.

"It's so beautiful! My BB! Ju Zhuo, deputy captain of the Air Force Brigade, radiated a brilliant light on his face, and his heart was full of incomparable joy.

In order to return to China to participate in the construction of the Air Force, Ju Zhuo sent 18 telegrams in North America in a row, and finally got the approval of the Executive Committee and returned to Taiwan from North America.

Ju Zhuo was originally a native of Guangdong, he saw the airship performance in Guangzhou when he was a teenager, and was immediately fascinated by it, and became a BB party member in the air, Ju Zhuo's dream is to build a "Kirov" airship made of black technology.

"A big-bellied pregnant woman, a beautiful ball!" You Qibing, the captain of the Air Force Brigade, was very dissatisfied with Ju Zhuo's fanaticism for airships. You Qibing believes that according to the development of history, aircraft is king, and the focus of the team should be to develop the aircraft industry.

Ranger and Judra are in charge of the formation of the Crossing Team Air Force, and both of them have a hobby of traveling in the blue skies. It's just that the Rangers are the Aircraft Party, and Ju Zhuo is the Air BB Party.

The Air Force's planes are ready-made, and the two Chujiao-6 planes ordered by the Executive Committee from the original time and space have already arrived at Taiwan's Taoyuan Airport. However, the crossing team lacked the fuel needed for flight, second, they did not want to artificially promote the process of aviation development too quickly, and third, they also wanted the European and American powers to consume too much financial and material resources on airships, so the working committee adjusted production capacity and developed an eye-catching airship for the Air Force.

You Qibing is a pragmatist, and the two beginners are locked in the hangar of Taoyuan Airport, not allowed to fly in the sky, and he can only shift his interest to airships.

This airship was produced by Lin Youde, Ju Zhuo and others according to the design drawings of modern airships, and was named "Huafu 1".

The airship is 58 meters long and has a maximum diameter of 10 meters, and the airbags are made of aluminum-magnesium alloy frames, and inside are 27 special airbags with flame retardant treatment. The pod is 6 meters long, 2.5 meters wide, and has an interior height of 2 meters. The power is two battery-powered electric motors, twin propeller drive, which can carry 8 passengers in addition to two drivers, or carry 1 ton of cargo.

The airship had been pushed out of the garage, and the sunlight shone on the silvery-white shell, immediately radiating a dazzling silver-white light.

"See! The silver shines and the beauty is stunning. Ju Zhuo's mouth grinned, "In the middle of the nineteenth century, this is the masterpiece of Heavenly Creation, Zhuge Immortal and the like, which can dominate the world for at least twenty years." ”

"Not bad!" Looking at the fantastic airship, You Qibing's heart was also full of joy, "It is definitely a technology tree that can bring crooked ghost animals." ”

"How can you say it's a crooked tech tree?" Ju Zhuo pouted, "In the nineteenth century, there were only airships, not airplanes. ”

"That's right!" You Qibing was happy, "Seeing that the airship is indeed effective, the ghost animals came to purchase it in a big way, and our aviation industry has developed at once." ”

In addition to the two Beginner Six, the Air Force also brought twenty Grayback Falcon aircraft engines, as well as a large number of aircraft technical drawings and work manuals. You Qibing believes that as long as the aviation industry chain matures, the aircraft will naturally go off the production line.

There is a large cross in the center of the field outside the airship hangar.

The soldiers of the ground support squadron carefully pushed the solid tires under the pod, and little by little moved the airship into the cross circle. There is also a long ground wire dragged under the pod, which is to release the static electricity of the airship and avoid accidental explosions.

On the edge of the site, there is an ambulance, a simple fire water truck, and a row of fire extinguishers on the ground.

Wang Tiezhu, Lin Youde and others stood on the side of the fire water truck, paying close attention to the site transfer of the airship.

Seeing that the airship was pushed into the cross circle little by little, Sima Ye breathed a sigh of relief and jumped out of the ambulance with confidence. She received an emergency notice in the morning, and ran over in a daze, only to learn that it was to ensure the safety of the hydrogen airship's flight preparations.

Sima Ye squeezed to Wang Tiehammer's side, "Wang Sima, why is this air bag filled with hydrogen?!" It's too dangerous! ”

"It's a little dangerous, but it's okay." Wang Tie hammered haha, "Speaking of which, this is actually much safer than the flight of an airplane." ”

For the safety of the hydrogen airship, Lin Youde put all his thought into the design and construction. He also gave a lot of explanations about the doubts of some people in the Executive Committee.

Seeing that the sanitary mouth also came to engage in popular science and questioned the safety performance of the hydrogen airship, Lin Youde grinned and said, "You know, I hit the airship airbag with a bullet, and there is nothing wrong!" ”

"Beware of leaks! Beware of leaks! Wang Tiehammer was worried that Lin Youde would break the news, so he hurriedly waved his hand and asked the staff officer Ye Qin to drive the natives beside him aside.

"This, how is this possible?!" Sima Ye's eyes widened in disbelief.

Sima Ye has read a lot of popular science articles, and when it comes to using hydrogen as the power of the airship, she will naturally think of the accident of the "Hindenburg" airship.

On May 6, 1937, the airship "Hindenburg" was destroyed by fire in a catastrophic~ accident, and at least 36 of the 97 passengers and crew died.

"How could it be!" Lin Youde pursed his lips and lowered his voice, "Do you know, during World War I, Germany sent zeppelins to bomb Britain, and the British's bullets and shells pierced the airship's hydrogen airbag N times, but the airship didn't do anything." ”

"No, it won't!"

"It's true." Wang Tiehammer smiled and nodded, "It wasn't until the British used white phosphorus bombs that the Zeppelin encountered real danger. ”

"Nahindenburg~~"

"The Hindenburg is just a small probability." Lin Youde was a little impatient, "From the ascension of the first hydrogen airship to the Hindenburg accident in the eighteenth century, in the past 150 years, there have been only a handful of major hydrogen airship accidents. There is only one Hindenburg that you can remember. ”

"But what if~" Sima Ye became more serious, and his tone became sharp.

"Don't worry, we will never treat the lives of our comrades as a child's play!" Wang Tiezhu hurriedly explained, "Look at the dazzling white shell of the airship, we use magnesium chloride-alumina coating, which is absolutely flame retardant. More than two dozen airbags are also made of flame-retardant materials. Even in the event of an accident, the airship airbags will at most burn one by one, not explode. Passengers in the pod have plenty of time to parachute out. ”

"That's it!" Sima Ye's mood calmed down a lot, "But I still feel that helium is safe, and this hydrogen balloon looks like a huge burning ~ burning bomb." ”

"Helium is being mined in Texas, USA, and the North American rudder will be coming soon. We are only using hydrogen for experiments now, and the number of flights will not be too many, and the probability of accidents is absolutely zero. ”

Hydrogen is a very readily available gas, while helium is an inert gas that is difficult to produce compounds, and its content in the atmosphere is low, only about five parts per million, and the production is quite pitiful. The only place in this time and space that can produce helium on a large scale is the United States.

Seeing Sima Ye leave satisfied, Lin Youde snorted coldly, "You just fool around!" If you don't solve the problem of cryogenic liquefaction, how do you transport a large amount of helium? ”

"Am I wrong! Sooner or later, helium will be shipped. Wang Tie hammered Lin Youde's shoulder, "The emotional girl was meant to be coaxed, you don't pity the jade too much!" ”

As he spoke, the airship was ready to fly.

In front of the airship pod, Ju Zhuo took Wang Baohua and Chen Changbao to salute Wang Tiehammer solemnly, "The airship is ready, please take off!" ”

The king's hammer is also a solemn salute. He didn't speak, walked straight over, checked the parachute bags carried by the three people one by one, and then bowed his hand to the three of them, "Stay safe!" ”

"Please rest assured, chief!"

The three of them walked into the pod and closed the hatch.

The air temperature, air pressure, wind direction, wind speed, and humidity were verified, and the airship was allowed to take off.

The horizontal flight of the airship is powered by the engine, and its lifting control is all dependent on the auxiliary airbags and counterweights inside the airship.

The gas inside the airship is composed of two parts, one is the floating gas bladder and the other is the auxiliary air bag (the inside is air). The ascent and descent of the airship is achieved by adjusting the amount of gas in the auxiliary airbag by the fan

The outer airbag is filled with helium, and the inner airbag is air. When the inner airbag is filled with air, the volume increases, the volume of hydrogen in the outer airbag decreases, and the buoyancy decreases. The inner airbag draws out the air and decreases in volume, while the volume of helium in the outer airbag increases, and the buoyancy increases.

With Ju Zhuo's command, the soldiers of the two flight captains operated in an orderly manner. Air began to be discharged from the airship's auxiliary airbag, and the upward ascent of the hydrogen airship slowly increased, and the airship slowly rose into the sky.

"Deputy Captain, is this true! We're really flying! Wang Baohua was a little excited. Wang Baohua was originally a farmer's child outside Zhenhai City, and after going to private school for a few days, he never thought that he would be able to fly into the sky.

Chen Changbao's face was a little pale, but his head was very clear, and he started the propeller with his hands and feet.

"Well done! Take it easy. You Qibing gently patted Chen Changbao's shoulder, "We are now the first person to fly in Huaxia, how beautiful it is to see the earth from above!" ”

Driven by the propellers, the airship slowly climbed southeast direction.

The mountain-like airship slowly climbed in people's eyes, flying higher and higher, which attracted the attention of the people of Keelung, "Fly, fly, really fly!"

Watching the sunlight shine on the airship's airbag, emitting ten thousand silver rays of light, like a magic weapon of the gods. The head of the Big Chicken Coop Society, Ah Lang, led all the people to prostrate on the ground, and worshiped the airship in the air reverently.

Chen Changbao's mood calmed down, and he looked down from the porthole, and the houses, objects, and people on the ground were gradually getting smaller. The sun shines golden on the surrounding mountains and the sea. He looked up again, and the blue sky was so vast that it stretched as far as the eye could see.

"The wind is urgent, the sky is high, and the water is clear."
