The National Policy Discussion Conference is still in full swing with intense discussions.
As for Laoshan, the Kyushu Academy of Sciences has made the latest breakthrough.
Amidst the sound of 'rumbling' all over the sky, in the year 10002 of the New Calendar, the first aerospace airship in more than 10,000 years of history rose into the sky...
Gale Tower, Skydiving Mountain.
The sky is all clear and paragliders are not allowed to take off today.
Common people from all over Qingdao County came to watch and witness this great historic moment.
An oval-shaped airship made entirely of oilcloth and with a volume of more than 100 cubic meters began its final engine test.
People from 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. After being filled with hydrogen, the estimated load capacity is 1,800 kilograms."
Fang Hanxian exclaimed: "So powerful? Can you pull more than a ton?"
"No, it's not. It's the estimated load capacity, including the airship's own weight."
"Ah? Then... doesn't it mean that you can lift two hundred kilograms to the sky? Four hundred kilograms? Two people?"
Fang Hanxian sighed, then this is of no use.
Villagers from Dafengtai volunteered as laborers and used steam trucks to transport cans of hydrogen prepared in advance.
With the command to 'inflate'
Everyone began to fill the deflated airship with hydrogen in an orderly manner.
'簌簌猌'
As hydrogen gas continued to be poured into the airship, the airship's hull began to expand.
When the people from the Aviation Academy saw the airship starting to shake, they immediately shouted hysterically: "Put on the chain. Hurry up, put on the chain."
"What? What kind of chain?"
"If you don't put on the chain to catch it, it will fly away. You can't even pick it up."
Everyone woke up as if from a dream. Yes, the airship was filled with hydrogen and it would lift off on its own. If it floats to the sky as soon as it leaves the ground, who can stop it
Although everyone has designed the safe operation of airships, the problem is... some are afraid to try to fly an airship.
Not because I'm afraid of heights.
The main thing is that the hydrogen inside the airship is flammable and explosive. There is an internal combustion engine working inside, and the high temperature generated is very likely to detonate the airship.
The people at the Kyushu Academy of Sciences have no confidence in the safety of the airship built in such a hurry. People who have personally participated in manufacturing must be worried...
Someone quickly tied the airship with a chain, and then tied the other end of the chain to the steel frame of a large steam vehicle.
At this moment, a gust of wind suddenly came up.
But the airship shook twice and suddenly floated up.
"Hey hey hey!"
A villager on the airship who was holding a hydrogen tank and inflating the airship exclaimed, holding tightly to the guardrail of the airship with both hands. Looking at the ground farther and farther away, screaming: "Help me, help me."
With a 'collapse' sound, the chain suddenly tightened.
The steam car shook a little, but it pulled the airship.
The people below all breathed a sigh of relief. This airship is too dangerous...
The villagers above were so scared that they were almost flown into the sky like kites.
"I want to come down. You guys help me tighten the chain, and I will slide down holding the chain."
He didn't dare to delay for a moment and was about to come down.
The villagers shouted: "What are you afraid of?"
"It won't be easy if you come down and send someone up again."
"Just stay up there. It's pulled by the chain, so it can't fly."
"What if? What if?"
"There is no chance. The power of the airship is not enough to break the chain."
“…”
Fang Hanxian also shouted: "It's not filled with the expected amount of hydrogen yet. We'll pass the can to you. You can fill it up before you come down."
"Oh well."
“…”
As a result, the villagers began to inflate the auxiliary airbag 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 airship's ascent conditions.
By releasing the hydrogen in the auxiliary airbag, the airship can be lowered or suspended at a certain height.
There is no big complicated principle.
Part of it is learned from the hot air balloon, which is to load the airship with ballast. The weight of these things can add weight. If the ballast is dropped, the airship loses weight and continues to rise.
These ballasts would be phosphorus bombs, or bombs.
People at the Kyushu Academy of Sciences understand it. It’s not a big deal to know this principle, but the main problem is actually still that-hydrogen is flammable.
Too flammable.
When the material of the airbag inside the airship was determined, a fire occurred due to a leak of hydrogen gas. The air bag exploded immediately, and only one person's hair was burned off by the fire, without causing too many casualties.
But the explosion was so powerful that it left a psychological shadow on people. No one from the Kyushu Academy of Sciences dared to try it.
This thing is not just a paraglider or a hot air balloon. I'm not afraid of falling. The worst thing I can do is skydive. The problem is... this thing has a direct chance of exploding in the air.
Moreover, Li Zhen once said that there is an atmospheric pressure at a certain height. After entering that height, the airship will explode on its own. The internal pressure will collide with the external pressure or something, and it will collapse directly.
But what is that height, where is that height, and what are the specific circumstances. No one knows...
When the main and auxiliary airbags were inflated, Fang Hanxian muttered: "It shouldn't be. Did you make a miscalculation? I feel like the carrying capacity of this airship is larger than you expected."
Immediately a student went to recalculate.
They used a tension scale to loosen the tight iron chain, and then hung the two ends of the tension scale on both ends of the iron chain. When the chain was straightened again, an intuitive data came out.
"Report, the current pulling force of the airship, that is, the lifting force, is 260 kilograms. There is still a person on the airship, and visual estimation predicts that his weight should be about 75 kilograms. Therefore, the total load capacity of the airship except its own weight, It should be three hundred and thirty-five kilograms."
Fang Hanxian took a breath of air: "More than six hundred kilograms. It can carry two people on it. It also contains hundreds of kilograms of phosphorus bombs. It's a bomb. A weapon of war, this is definitely a weapon of war!"
After hesitating for a while, Fang Hanxian said: "Who is that? Come down."
"okay."
The villagers came down.
Fang Hanxian asked: "Does anyone want to be the first pilot in history?"
Everyone took a step back.
Fang Hanxian chuckled: "I'll do it."
When people from the Kyushu Academy of Sciences saw Fang Hanxian taking the lead, they no longer gave up:
"I'll do it, Dean."
"Dean Fang, you are from the Electromagnetic Institute. This should be done by people from our Aviation Institute."
"Let me do it."
"I come."
“…”
People at the Aviation Institute felt deeply that they had no face. Even if it was just to save face, they had to take risks.
It was finally determined that a staff member from the Aviation Academy named Zhang Zixiao would conduct the first test flight.
After Zhang Zixiao boarded the airship, he first entered the cockpit and walked around to check whether the instruments were normal. Then he shouted: "Pull down the chain, lower the height, and then you can bring me ammunition up. If I am alone, I need ballast. Otherwise it is not safe."
"Zixiao, don't use bombs for test flights. It's not safe."
"Let's get you some rocks to go up."
“…”
"That won't work. Since it's my turn to do a test flight, I'll do it thoroughly. Hurry."
"The main thing is...it's not easy to get you a bomb right now."
Zhang Zixiao rolled his eyes: "Get me a three hundred kilogram sandbag."
"good!"
When everyone brought the sandbags, Zhang Zixiao moved them all into the cockpit.
But at this time, everyone discovered that the chain was not so tight anymore. The airship is even somewhat suspended and seems to be descending.
