As far as Jiang Mubai knows, airplanes have not yet withdrawn from the stage of the times, and they are still the most popular aircraft, but they have become the exclusive domain of the elite class. For example, several governors in the Dingwu City Hall can fly 3,000 kilometers on a business jet for free every year.

However, now that fuel is in short supply, low-consumption, high-efficiency airships have replaced airplanes as the main civil aviation vehicles.

Compared with airplanes, although the airship has a low flight speed, it has a strong load capacity, and it is better than stability, cheapness and flexibility - the cost of airship is not cheap, but the cost of use and utilization efficiency are better than that of railways.

After more than 30 years of continuous research and development, the airship system has gradually matured, and the types and uses have been subdivided again and again, not only civil passenger, freight, sightseeing and advertising airships, but also meteorological airships, topographic mapping airships, environmental monitoring airships, disaster rescue airships and military reconnaissance, bombing, and transport airships.

Among them, the most common and widely used are cargo airships and sightseeing airships.

For example, the auspicious big butt in the outer mooring apron is designed based on the world's largest aircraft sky lander, with a total length of nearly 100 meters, a body width of about 50 meters, a body height of 28 meters, a maximum diameter of 30 meters, and a maximum load capacity of 30 tons, which is the most classic cargo airship model.

Jiang Mubai had seen the relevant information in the book before, but there were only a few simple data and blurry photos in the book, which could not intuitively reflect its enormity.

The height of the double-decker bus is about four meters, and the auspicious big butt is 28 meters high, 98.4 meters long, and 49.6 meters wide, which is as high as seven double-decker buses stacked and as big as a football field!

Even the Boeing 747-8, once known as the "giant of the sky", looks like a little brother in front of it, not to mention the electric cart used to load and unload cargo under the airship. From a distance, those electric trucks look like worker ants in their nests.

The red lantern one hundred and fifty meters to the right of the big butt is a sightseeing airship, which should be the private property of the airport management, and occasionally makes a cameo appearance in the advertising airship to increase profits and generate income for the owner.

Further to the right are the scud and Dongfeng 666 that Mao Dake said, these two airships Jiang Mubai has never heard of, but fortunately, there are airship experts Mao Dake who actively popularizes science.

There are new technologies such as carbon fiber anti-static cloth, static elimination device and anti-riot device, the safety performance of modern hydrogen airship far exceeds that of the ancestors who have been eliminated and abandoned, in addition, the aircraft can not use extremely efficient hydrogen fuel cells as a power source, and airships can, coupled with the high price of helium, hydrogen airships have naturally become the mainstream.

However, the Dongfeng 666 is designed for short- and medium-distance voyages, and in order to ensure the safety of passengers, most passenger airships use inert gas to provide lift.

After listening to Mao Dake's popular science and reading the introduction manual provided by the airport for free, Jiang Mubai was once again convinced that the scientific and technological level of the world today has not regressed by leaps and bounds as it seems on the surface, but for some unknown reasons, the federal government has deliberately controlled and suppressed information technology.

Perhaps, this has something to do with the big lie that Old Man Ying said.

Half an hour later, when it was time to board the boat, Jiang Mubai walked to the Dongfeng 666 airship berthing with the flow of people with mixed thoughts, followed the folding ladder to the airship cabin, and then found a seat under the guidance of the flight attendant, fastened the seat belt, and waited for takeoff.

Jiang Huiyin and Mao Dake, the two little girls, sat by the front window, chattering non-stop, and Shi Guangwen sat in the seat directly behind Jiang Mubai, looking through the palm-sized comic strip he had just bought in the terminal.

Lin Chujin took a seat after putting down the paper umbrella, and she was a little surprised to see Jiang Mubai sitting next to her.

"So coincidentally?"

"It's not a coincidence, I saw the seat number on your boarding card and found someone to change the seat." Jiang Mubai gave full play to the advantage of being cheeky and generously told the truth.

"Eagle sight, bat hearing, elephant smell, it is really extraordinary." Lin Chujin covered her lips and chuckled, "Can you hear my heart racing?" ”

Eagle vision bat hearing elephant smell, as the name suggests, is that after Wu Xiu fully developed the human body secret, he has the vision of an eagle falcon, the hearing of a bat and the smell of an elephant, Eagle vision does not need to be repeated, bats listen to elephant smell are particular, the eyes of bats are almost useless, they all rely on emitting ultrasound and echoes to identify objects, and the elephant smell gene is more than 2,000, and it is likely to be the mammal with the sharpest sense of smell - after all, its strength is the nose.

"No, because your heart isn't beating, but I can smell you."

Jiang Mubai didn't mean to flirt lightly, and said seriously: "It's not the smell of perfume or soap, and it doesn't look like pheromones." ”

Lin Chujin explained: "Well, it's actually not my fragrance, but the smell of the micro-spirits on my body. ”

"Micro spirits?" Jiang Mubai frowned slightly, it was another new word that he had never heard of.

Lin Chujin nodded: "It seems that there is also a name called 'directional microorganism', well, it is the same as the 'pheromone' you said, it is a biological term, and I don't know much about it." Yedu also has a micro-spirit body cultivation center, if you are interested, you can check it out. ”

It turned out to be microorganisms, but I had heard the news that scientists were trying to modify the genes of microorganisms and use them to make perfumes, and it seems that this research has been successful.

If nothing else, this is yet another example of how technology has not regressed.

Jiang Mubai agreed, and was thinking about how to knock on the side to find out the reason for the Cloud Sword Sect's self-destruction of the Dao Fruit, when he was suddenly pierced by a sharp and strange noise.

"Shut your ears!" Shi Guangwen patted Jiang Mubai's seat, "Hey, I patronized the villain book and forgot that it was your first time to take an airship." ”

Jiang Mubai didn't ask much, and immediately reversed the qi and blood in his body, temporarily blocking his ears and depriving himself of his ability to hear. Without superhuman hearing, the noise suddenly disappeared.

"What's that sound?" Jiang Mubai asked.

Shi Guangwen shrugged his shoulders and pouted: "I don't know, anyway, I can't hear if I close my ears, and it will be fine after a while." ”

"It's an ultrasonic bird repellent, we can't hear it, we can only hear it when we open our ears." Mao Dake turned his head and looked at Jiang Mubai from the gap in his seat and said, "The airship is about to take off, and we will be fine when we reach the cruising altitude." ”

If it is really like things, people are grouped, and the little girl who is a neighbor with Xu Qian is so knowledgeable, Jiang Mubai gave her a thumbs up and asked, "I know so much, where did I learn the knowledge?" ”

Mao Dake sniffed and said triumphantly: "I have a TV at home, I have watched a lot of airship documentaries, this is nothing, I will apply for the Aerospace Design and Research Institute of Tianjing University in the future!" ”

Outside the cabin, the ground crew untied the fixed rope tied to the berthing pole position, so that the Dongfeng 666 could retract the hook of the head cone. At the same time, the control tower signals, and the pilot in the cab begins to operate the control lever and dial to inject compressed helium into the air bag.

When the lift force is equal to the overall weight of the airship, the belly of the airship discharges ballast water to the ground container, and then the airship quietly rises into the air under the announcement of the flight attendant.

In the line of sight, everything on the ground was slowly shrinking, the ground crew on the tarmac were like ants, and the huge airship was shrunk into a small balloon.

After a while, patches of white swept from top to bottom outside the window, making the children who were riding the airship for the first time exclaim.

After passing the low altitude Cumulus altitude, the Dongfeng 666 reached the cruising altitude of the passenger airship, and then started the engine and continued to accelerate, flying towards Yedu at a speed of 150 kilometers per hour.
