Chapter 270: Airship
The national policy discussion conference is still in full swing and is still being hotly discussed.
And in Laoshan, the Kyushu Academy of Sciences has the latest breakthrough.
In the sound of 'booming' in the sky, in the year 10,002 of the new calendar, the first aerospace airship in more than 10,000 years of history rose into the sky......
Big Wind Terrace, Parachute Mountain.
The air is all empty, and paragliding is not allowed to take to the air today.
The ordinary people of the entire Qingdao County came to watch and witness this historic moment.
An elliptical airship made of tarpaulin with a volume of more than 100 cubic meters began its final engine tests.
The people of the Kyushu Academy of Sciences took professional tools and tested the final data.
"Report."
"Speak."
"The total weight of the airship is 1,600 kilograms. When filled with hydrogen, the expected load capacity is 1,800 kilograms. ”
Fang Hanxian exclaimed: "So powerful? Can you pull more than a ton of things? ”
"No, it's not. It is the estimated load capacity, and it is all included in the weight of the airship. ”
"Huh? That...... Wouldn't that be able to pull 200 kilograms to the sky? Four hundred pounds? Two people? ”
Fang Hanxian sighed, then there is a bird for this.
The villagers of Dafengtai volunteered to work as laborers, using steam trucks to fill tanks of hydrogen prepared in advance.
With a command to 'inflate'
Everyone began to methodically fill the deflated airship with hydrogen.
'簌簌簌'
As hydrogen continued to pour into the airship, the hull of the airship began to swell.
As soon as the people from the Aviation Institute saw that the airship was shaking, they immediately shouted hysterically: "Get on the chain." Hurry up, get on the chain. ”
"What? on what chain. ”
"If you don't pull it on the chain, it'll fly away. I can't pick it up. ”
Everyone woke up like a dream, yes, the airship was filled with hydrogen, and it would take off on its own. If it's going to float up to the sky as soon as it leaves the ground, who can you catch it?
And although the safe operation of the airship has been designed by everyone, the question is ...... Some of them were afraid to try to fly an airship.
It's not because of fear of heights.
The main thing is that the hydrogen inside the airship is flammable and explosive. And there is an internal combustion engine working inside, and the high temperature generated is very likely to detonate the airship.
And the people of the Kyushu Academy of Sciences have no confidence in the safety of the airship built in such a hurry. Those who have participated in the manufacturing process themselves will definitely not be at ease......
Someone quickly tied the airship with an iron chain, and then the other end of the chain was tied to the steel frame of a large steam car.
At that moment, a gust of wind suddenly rose.
But I saw the airship shake twice, and suddenly floated up.
"Oops!"
A villager on the airship holding a hydrogen tank and inflating the airship exclaimed, holding the guardrail on the airship with both hands. Looking at the ground farther and farther away, he screamed, "Help me, save me." ”
With a 'crash', the chain suddenly tightened.
The steamer shook for a moment, but it dragged the airship to its feet.
The people below breathed a sigh of relief, this airship was too dangerous......
The villagers above were also paralyzed with fright, and they were almost released into the sky like kites.
"I'm coming down. You helped me tighten the chains, and I slipped down with the chains. ”
He didn't dare to delay for a moment, and he was about to come down.
The villagers shouted, "What are you afraid of?" ”
"If you come down, it's not easy to send someone up."
"You just stay up there, it's chained, it can't fly."
"What if? What if? ”
"No in case. The strength of the airship was not enough to break the chains. ”
“……”
Fang Hanxian also shouted: "There is not enough hydrogen in it, we will hand you a jar, you can fill it up and come down." ”
"Okay then."
“……”
So, the villagers began to inflate the auxiliary airbags again.
The entire airship has two airbags, one is the main airbag and the other is the auxiliary airbag.
The main airbag is responsible for generating some lift, and the auxiliary airbag is completely responsible for the ascent conditions of the airship.
By releasing the hydrogen in the auxiliary airbag, the operation of lowering the airship or levitating it at a certain height can be completed.
There is no big complicated principle.
Part of it is about hot air ballooning, which is loading the airship with ballast. The weight of these things can add weight. If you drop these ballasts, the airship loses weight and then continues to rise.
These ballast will be phosphorus bombs, or bombs.
The people of the Kyushu Academy of Sciences understand and know that this principle is not a big deal, but the main problem is actually that one - hydrogen is flammable.
It's too flammable.
When the material of the airbag inside the airship was determined, a fire was caused by a little hydrogen leakage. The airbag exploded directly, so as long as a person lost his hair by the fire, it did not cause too many casualties.
But that explosion was also too powerful, leaving a psychological shadow on people. The people of the Kyushu Academy of Sciences did not dare to try.
It's not paragliding, it's hot air ballooning or anything like that. I'm not afraid of falling, it's a big deal to skydive. The question is...... There is a direct possibility that this thing will explode in the air.
Moreover, Li Zhen once said that there is an atmospheric pressure at a certain altitude. After entering that height, the airship will explode directly on its own, and the internal pressure and external pressure will collide or something, and it will directly disintegrate.
But what is that height, where is that height, what is the specifics. No one knows......
When the main and auxiliary airbags were inflated, Fang Hanxian muttered, "It shouldn't be." Did you miscalculate? I feel like this airship has a larger payload than you estimated. ”
Immediately there are students who go to recalculate.
They used a tension scale, loosened the taut iron chain, and then hung the two ends of the tension scale on each end of the chain. The chain is straightened again, and an intuitive data comes out.
"According to the report, the pull of the airship, that is, the lift, is now 260 kilograms. And there is still a person on the airship, and it is estimated that his weight should be about seventy-five kilograms. Therefore, the full load capacity of the airship, except for its own weight, should be in the range of three hundred and thirty-five kilograms. ”
Fang Hanxian gasped: "More than six hundred catties." This can go up to two people. As well as pulling hundreds of pounds of phosphorus bombs, bombs. Weapons of war, this is definitely a weapon of war! ”
After hesitating for a while, Fang Hanxian said, "Who's that." You come down. ”
"Okay."
The villagers came down.
Fang Hanxian asked, "Does anyone want to be the first pilot in history?" ”
Everyone stepped back in unison.
Fang Hanxian smiled: "I'll come." ”
As soon as the people of the Kyushu Academy of Sciences saw Fang Hanxian taking the lead, they were no longer afraid:
"I'll do it, Dean."
"Dean Fang, you are from the Institute of Electromagnetism. This should be done by the people of our aviation institute. ”
"Let me do it."
"I'll come."
“……”
The people of the Aviation Institute feel that they have no face, even if it is for the sake of face, they have to take risks.
It was finally decided that a staff member of the Aviation Institute named Zhang Zixiao would carry out the first test flight.
After Zhang Zixiao boarded the airship, he first entered the cockpit and swam around to check whether the instrument was normal. Then he shouted: "Pull the chain down, lower the height, and then you will bring me ammunition." If I'm alone, I need ballast. Otherwise it is not safe. ”
"Zixiao, don't use bombs for test flights. Blame it for not being safe. ”
"I'll get you some rocks to go up to."
“……”
"That's not good, since it's time for me to test fly, once thoroughly. Hurry. ”
"Mainly...... It's not good to get you a bomb right now. ”
Zhang Zixiao rolled her eyes: "Get me a three-hundred-kilogram sandbag." ”
"Good!"
When everyone brought the sandbags, Zhang Zixiao moved them all into the cockpit.
At this time, everyone found that the chain was not so tight. The airship is even somewhat suspended and seems to have a downward trend.
