Chapter 260 The Big Mac
At the same time.
The Minqin Airship Factory, which detonated seven experimental airships in succession, finally collected various experimental data.
They also knew the critical point of airship explosion, burning and leaking.
In the past 200 tests, the probability of leakage of airship hydrogen airbags will cause explosions is very small, especially when airship hydrogen airbags leak, and there will be no explosions.
Either leak directly into the air and then float toward the higher atmosphere.
Or constantly jetting during the leak.
The reason why explosions are not prone to occur is that hydrogen explosion requires a specific concentration, and after mixing with oxygen, a certain mixing ratio is formed.
This special proportion is difficult to form during air flight.
After all, during air flight, the air flows very fast, and it is difficult for hydrogen to form a specific concentration in a region.
On the contrary, combustion is the biggest risk after hydrogen airbag leaks.
In order to deal with the situation of hydrogen leakage during airship flight, and the combustion occurs after the leakage, the airship company has made technical improvements and formulated their respective emergency plans.
For example, between the airbag and the skin, a large number of annular airbags are arranged, and these airbags are filled with carbon dioxide to isolate the contact between hydrogen and oxygen.
Even if hydrogen leaks and is ignited in misfortune, it will burn through the carbon dioxide airbag as soon as possible, causing carbon dioxide to overflow from the burned through position, thus hedging with the burned hydrogen.
And carbon dioxide airbags have another purpose, which is to adjust the buoyancy of the airbag through liquefaction and gasification, so as to facilitate the airship to adjust the overall buoyancy.
At the same time, once the internal hydrogen airbag is received, a large amount of carbon dioxide will begin to be emitted in the liquid carbon dioxide storage tank of the carbon dioxide airbag, or the internal hydrogen airbag is ruptured, thereby maintaining the concentration of carbon dioxide inside the airship, and squeezing the surrounding air oxygen closes, providing the driver with emergency time.
Of course, these hydrogen airships are all unmanned, so the drivers control the airships remotely. When encountering emergencies, they need time to deal with them.
As each improvement plan is completed.
The first transport airship that can be used for experimental flights: Blue Whale Type 1 1001 was finally completed at the end of November.
This airship is over 200 meters long and has a height of more than 50 meters.
It has 270,000 cubic meters of hydrogen airbags inside, which can achieve a payload of 200 tons in airspace below 3,000 meters above sea level.
The maximum takeoff weight is 320 tons and the maximum payload is 200 tons.
The maximum flight altitude is 12,000 meters above sea level, and the cruise flight altitude is less than 3,000 meters above sea level.
The maximum flight speed is 150 km/h, and the cruise flight speed is 60 km/h to 120 km/h.
The maximum range is 13,500 kilometers, and the maximum range under maximum load conditions is 4,500 kilometers.
In the airship dock of the airship factory, hydrogen airbags are filled with hydrogen. Just in case, there are no people inside the dock at this time, and it is also filled with a large amount of carbon dioxide to isolate oxygen.
Hou Xin, chief designer of Blue Whale Airship, and Wan Gaofeng, general manager of Airship Company, are all in the nearby underground bunker base.
"Report, the airship hydrogen airbag has been inflated."
"Report, the tied cable bears tension of 308 tons, which does not meet the take-off buoyancy."
"Report, the hydrogen concentration of the outer interlayer of the airship is zero, which meets the take-off indicators."
"Report..."
Wan Gaofeng glanced at the time of the watch, and then ordered: "Start recycling the carbon dioxide inside the dock."
"Receive!"
A large amount of air was sucked in on the light dome built with a silicon wire structure, and the suction channel at the bottom of the dock was also opened, sucking away the carbon dioxide inside.
"Report that the tension of the airship's tethered cables has decreased..."
As the concentration of carbon dioxide inside the dock decreases, the buoyancy of the airship is also decreasing, because the density of carbon dioxide near the ground is relatively high, about 54% heavier than the air, which will lead to a buoyancy of the airship being increased by 54%.
Soon the carbon dioxide inside the dock was replaced by normal air, and the buoyancy of the airship also dropped to 200 tons.
"The airship buoyancy meets the takeoff indicators."
Wan Gaofeng ordered again: "Open the dome."
"Received."
The airtight locks on the top of the dome automatically open, and then the bottom of the dome begins to slowly move with the tracks on both sides. It looks like a behemoth of hundreds of meters in length and hundreds of meters in height. In fact, due to the large amount of lightweight silicon bean silk composite materials, its overall weight is only about 15% of the steel.
You can slowly pull through the track.
As the dome structure moves to both sides as a whole, the dock in the middle also reveals its true face.
A top half is covered with black silicon carbide photovoltaic panels, and the lower half is painted with a huge blue-gray airship, which appears in the camera.
You can also see this behemoth when passing by remote sensing satellites in nearby outer space.
"Report, the dome has been fully opened."
"Released the dock ties cable."
"Received."
"The dock ties cable has been released."
Wan Gaofeng looked at the data on the console, leaving only four of the airship's own tied cables, each of which can independently withstand about 70 tons of tension, which can ensure that the airship is firmly fixed.
"Release the airship's tethered cable."
"Received."
As the airship's own tethered cable was lifted, the airship slowly floated upwards until the airship adjusted the buoyancy well through the internal buoyancy adjustment system, so that the airship could steadily float at a height 50 meters from the ground.
Soon after the pilot's remote control, the airship flew to the Minqin Airport in the south of the Minqin High-tech Industrial Park. Staff from Minqin Airport detected the approach of the airship through radar.
The airship itself carries communication systems, positioning systems, etc. Due to its huge size and huge load, it can carry more equipment, so it is relatively easy to control.
In addition, the airship is not fast at a time, which is convenient for the driver to control remotely.
Although the northwest wind in Minqin was very strong at this time, facing the huge airship and amazing weight, the strong wind could not cause the airship to deviate greatly.
And the current automation equipment and wind regulation systems are no longer what they were decades ago. The wind power brings various interferences and can be corrected through automation equipment.
"This is Minqin Airport, and the airship number 1001 is received and please return."
"Received, this is airship No. 1001, we requested to berth."
"1001, your request is passed, please park at berth No. 5..."
The various control equipment and positioning equipment on the airship are more dense than the calculating aircraft. Soon the airship was accurately parked 50 meters above berth No. 5 of Minqin Airport.
Pull the 6 fast shelf tractors with 20-foot containers and pull the shelves directly under the airship.
No mistakes, one poem, one post, one content, one in 6, one book, one bar, one read!
Then several staff members quickly pulled up the cargo cable thrown by the airship and fixed it to the shelf.
"1001 airship, the shelf cables have been fixed."
"Received, please evacuate as soon as possible."
"Received."
Three minutes later.
The tractor and staff were evacuated to a safe area.
"1001 airship, our staff and equipment have been evacuated and can be lifted."
"Received."
The airship's motor starts up and pulls up the shelves and containers.
After a short while the container and the shelves were pulled into the warehouse on the abdomen of the airship and fixed it.
After a while, the airship untied the cable and flew quickly towards the Weicheng direction of Qin Province.
Because the airship flies from northwest to southeast, just flying down the wind, its speed quickly increased to 120 kilometers per hour.
In order to facilitate this test, along the way, the airship company also set up several communication relay stations and sent a tracking fleet.
However, until the driver's remote control fails, the ground fleet will not intervene in control.
Flying directly from Minqin to Weicheng is about 750 kilometers.
First pass through the southwest of the Tengger Desert.
The deserted southwest of Tengger Desert has been transformed into soybean farms at this time. However, the soybean farm in winter, looking from the sky, it is a large square, plus the farm factory and dormitory area that embellishes it.
It was not until the river channel near Heishan Gorge of the Yellow River that it was obvious that there was obvious population on the ground.
Into areas with relatively dense towns, in order to avoid entering the sky above the city, the airship had to maneuver and specially selected wilderness ridges as the route.
Konghe Town near Pingchuan District.
Wang Dali, who was in the middle of the cat, had just gotten out of the car. He looked at his own field: "Huh, it's so cold!"
Suddenly he widened his eyes.
I saw a blue and black behemoth flying quickly from the northwest direction. "What?" Wiped his eyes and looked at it again. Wang Dali murmured to himself: "What is this U? "
Although he was not sure, he still picked up his phone and took a video.
Soon the residents around also discovered this behemoth.
By bypassing the nearby Quwu Mountain and arrived above Fuxing Town.
Along the way, the airship attracted a lot of attention.
Because we have to bypass cities and mountains, the flight distance has increased by about 70 kilometers.
The whole journey took a total of 820 kilometers, with an average flight speed of 116 kilometers per hour. After only 7 hours, we successfully arrived at the Weicheng Airport near Weicheng.
People in Weicheng urban area can easily see the huge thing floating in the air.
"Damn! What?"
"Airship?"
"So big."
In particular, residents near the airport can see the airship when they look up and watch it below. That is the real shocking.
Full of oppression.
However, the airship did not stay for too long. It unloaded the artificial silk from 6 containers and pulled up the 6 containers of tropical fruits. The airship flew back to Minqin without stopping.
During the entire voyage, parking, unloading and loading, the ground convoy did not conduct guidance or assisted control, and all relied on remote control drivers near Minqin Airport to drive themselves.
Although this low-altitude route is temporarily applied, it is very considerate to all regions passing by.
This test flight soon caused heated discussion on the Internet.
