Chapter 268 New Ship
Ganzhou Province, northern.
The rising sun shines on the south bank of the Yangtze River, on the surging river water, illuminating golden waves.
The Jiangxin Shipyard in Hukou County has started a new day of busyness in the cold wind.
On a dock production line used to build fiberglass ships, a 2,000-ton inland transport ship, has completed construction work.
Li Guangjian, the designer who was responsible for designing the ship, chatted quietly with Duan Guohua, the head of the construction team, on the side of the dock.
"Old Duan, have the supporting facilities been installed?"
"Completed."
Looking at the gray-white hull in front of him, Li Guang saw a hint of worry in his eyes: "Have the intensity testing of various parts met the standards?"
Duan Guohua was very calm: "Don't worry! Designer Li, anyway, they are new ships for testing new materials, and the money is all from Hailufeng Company, so we can relax."
Because Hailufeng Company got off five boats at once for experiments.
Because the composite material based on silicon bean silk is very light in weight and has very high overall strength, it can make the overall lightweight.
Generally speaking, inland transport ships can be divided into five systems, namely: hull structural system, power system, electrical system, outfitting system, and ballast water system.
The current increasingly popular electric transport ships can actually be combined into electrical systems.
The four systems of electric transport ships each occupy the ship's own weight: 55% of the hull structure system, 30% of the electrical system, 8% of the outfit system, and 7% of the ballast water system.
After the use of new materials, the hull structure system, outfitting system, and ballast water system can all be reduced to varying degrees.
The five experimental transport ships they are currently building use 5 different weight reduction plans.
Plan No. 1, overall weight loss is 52%;Plan No. 2, overall weight loss is 45%;Plan No. 3, overall weight loss is 42%;
Plan No. 4 will reduce the overall weight by 37%; Plan No. 5 will reduce the overall weight by 34%.
It is obvious that solution No. 1 is an extreme weight reduction solution, which will reduce parts that can reduce weight to the maximum extent.
The ship built by this plan is the one in front of Li Guangjian.
At present, according to the estimates they said, the experimental ship of the No. 1 program has a self-weight of about 360 tons. Under full load, it can carry 2,390 tons of cargo, which is about 390 tons more than ordinary electric transport ships.
"Old Duan, I know that the company does not need to bear the losses to build these experimental ships, but I am worried that the test will not be passed." Li Guangjian was uneasy.
Duan Guohua patted his shoulder and comforted, "It's useless to think about everything here. Let these five experimental transport ships be launched as soon as possible. The airship will come tomorrow."
"Okay! I hope everything goes well."
As the two of them watched.
Five experimental transport ships completed the launch ceremony one after another. Since they were experimental transport ships, the shipyard did not make a big fuss.
After the water was launched, the testers began to check whether there was any leakage inside.
Then the test of the ballast water system began.
From morning test to evening sunset.
Each system is running well.
In fact, this is also very normal, because in the past six months, Jiangxin Shipyard has built a total of 17 electric inland transport ships and has accumulated a lot of experience.
Various problematic supporting systems have also been improved one after another.
At present, the electrical systems of electric transport ships are very mature. Using this relatively mature supporting system will basically not cause any major problems.
Looking at the preliminary test report in his hand, Li Guangjian breathed a little relieved: "The No. 1 ship is loaded with 2,390 tons, and there is no deformation of the skeleton and hull. You can have a good sleep tonight."
Duan Guohua smiled and comforted: "I said there is no big problem, designer Li, please relax!"
"Old Duan, let's go to have a meal first! There are still a lot of things tomorrow."
"Okay."
No words all night.
Early in the morning, it was just dawn.
Thin snowflakes floated in the shipyard.
Duan Guohua, Li Guangjian and others who had breakfast stood at the pier near the dock, looking towards the northwest.
The dark clouds and the snowflakes falling from time to time. "Hu..." Duan Guohua, who was breathing in white, rubbed his cold red palms: "The weather changes as soon as possible."
"Manager Duan, drink a bag of hot soy milk." An employee was carrying an insulated foam box, which contained a pile of small packages of hot soy milk and tea eggs.
Duan Guohua was not polite, so he took two bags, put one bag in his hand and warmed it up. He bite the other bag directly with his teeth and sucked it without missing a drop: "Huh... it's comfortable to drink hot soy milk in this weather."
Li Guangjian, who was eating tea eggs while drinking hot soy milk, suddenly stuffed the tea eggs into his mouth and ate them all in a hot soy milk like swallowing them: "Hi... is coming!"
"Come?" Duan Guohua raised his head and looked around the northwest.
I saw a blue dot slowly flying towards this side in the dark clouds in the distance.
Drinking off the soy milk in his hand in a few seconds, he picked up the telescope and observed: "Well, it's indeed here, but there's still a little distance."
Although they saw the blue dot now, it was because the airship was very large.
As the Blue Whale 3, which can lift 3,200 tons of cargo, its length reaches 583 meters, its diameter is 98.6 meters, and it has 2.7 million cubic meters of hydrogen inside.
Half an hour later.
The Blue Whale No. 3001 airship slowly anchored above Jiangxin Shipyard.
Standing under this airship, the feeling was really shocking and depressing. The whole sky suddenly became dark, and there was a feeling of hiding the sky and covering the sun.
Blue Whale Airship Company had sent people here a few days ago, bringing communication vehicles, signal guide vehicles and drone shielded vehicles.
In fact, the airship itself also comes with a drone shielding system.
In order to avoid some modified or homemade drones, they break through the drone shielding system and attack the airship.
A layer of silicon carbide nanotube braided mesh is specially installed on the outside of the airship.
The lines of these mesh are all high-strength, high-hardness silicon carbide nanotubes with a diameter of 140 nanometers. From the outside, these mesh are almost invisible to the naked eye unless carefully observed.
These protective nets are only a few hundred kilograms in total, but their protective performance is very high. Ordinary drones will instantly be cut into pieces when they hit these nanonets.
On the Minqin Airship Test Field, not only the impact and attacks of rotor drones have been tested, but also the attacks of fixed-wing drones, mortar shells, rockets, and missiles have been tested.
The result is that drones cannot penetrate the protective nanonet, and grenades and shells emitted by drones will also be blocked.
After all, this protective nanomesh is about 1 meter away from the airship's skin, and the surface of the airship is also a high-strength, high-hard silicon carbide nanotube woven skin and photovoltaic panel. There is also a layer of carbon dioxide airbag inside, which is also very strong. It is obviously not that easy to break through the three layers of protection and hit the hydrogen airbag inside the airship.
Even armor-piercing bullets with energy-gathering charges cannot produce effective destruction effects.
Because this protective net woven by nanotubes can cut the shells instantly. The faster the shells are, the faster they are cut.
As for the explosion and high temperature that occurs instantly in cutting, there is no use, and at most it will cause the paint on the surface of the airship to be painted off.
After all, silicon carbide nanotubes have very high hardness, and their strength and tensile strength are also very good. They can basically be compared with carbon nanotubes, and have high temperature resistance and high heat conduction characteristics.
Armor-breaking and energy-piercing armor-piercing bullets designed specifically for tank armor can only tickle the surface of the airship.
This is just the basic style.
If special designs are specifically designed for weapons such as armor-breaking bombs and rockets, such as adding several layers of protective nets, the armor is composited with silicon carbide nanotubes and aramid fibers, and composites several layers, plus hollow design, the metal jet cannot penetrate this protection system at all.
However, Hailufeng Company is not interested in this product, and several qualified companies in China have studied many strange samples. …
The Blue Whale 3001 airship was completed seven days ago and tested around Minqin for a few days before being sent here to test the gondola project.
Hu Renbo, the team leader who was sent, successfully took over the control of the airship from the remote control center with two temporary pilots.
Li Guangjian came over and asked, "Team Leader Hu, what's the situation there?"
"I have taken over the control and can start the test at any time." Hu Renbo glanced at his watch and said, "It's almost eight o'clock, where are you?"
"We are ready here too." Li Guang suddenly became nervous again when he saw that he couldn't change his bad habit. When he encountered big things, he would feel anxious unconsciously.
Seeing the other party's uneasiness, Hu Renbo said with a smile: "Designer Li, don't worry too much. Even if there is a problem in the test, our company will not blame you. After all, this shipbuilding cooperation is originally intended to test the overall strength of the ship."
You must know that in order to verify the safety of the hydrogen airship, Blue Whale Airship Company blew up more than a dozen airships of all sizes.
The five experimental ships are only tens of millions, and even if there is a problem, it will be a drop in the bucket for the company.
After all, this is a necessary expense in the innovation process. You can’t just put the product into use without safety testing! This is obviously impossible. Unless it is completely imitating the mature plans of other companies, don’t think about such good things first.
Since the Blue Whale Airship does not have a manned system, it does not need to think too much to complete the safety test so quickly.

As the need to transport passengers, Panshi Automobile has scrapped 278 experimental models since September, and various tests are still being continued.
The two sides discussed for a while before the first gondola test began.
In view of the testing process, during the first gondola test, the ship did not load any cargo and even the ballast water was unloaded.
The weight of 360 tons is simply a pediatric for the Blue Whale 3001, which can lift 3200 tons of cargo. However, this test is not to test the payload of the airship, but to test the overall strength of the ship.
In the wind and snow all over the sky.
By adjusting the hydrogen and carbon dioxide in the internal airbag, the airship slowly descends from a height of 100 meters to about 15 meters above.
Eight special cables were thrown off on the cable fixing frame on the abdomen of the airship, and the staff on the ship quickly clamped the cables onto the specially designed fixtures on the ship.
"Fixed."
"Re-check it."
"Okay."
After more than ten minutes, the crew on the ship came down, and everyone evacuated to a safe area.
As the pilot pressed the button to increase the buoyancy, the airship's buoyancy system began to increase the overall buoyancy, and soon the buoyancy exceeded the weight of the lifted ship, and the airship slowly floated up with the experimental ship.
After more than ten minutes, the airship had floated to a height of 100 meters from the water surface, but it was not enough. The airship continued to increase its buoyancy until the floating height reached 500 meters. The buoyancy increased.
Hu Renbo held the telescope and carefully observed the bottom of the experimental ship, while others were also watching with the telescope.
Li Guangjian put down his telescope and while noting the situation, he slowly said, "There is no obvious deformation."
"Do you want to fly around?" Duan Guohua turned his head and asked.
Hu Renbo nodded: "Yes, fly more than ten kilometers to see."
The pilot immediately understood and controlled the airship to fly at a constant speed along the safe area that had been cleaned up in advance. When he reached the end of the safe area, he slowly turned around and flew back according to the original route.
Immediately afterwards, I reduced my buoyancy and approached the water surface, and put the experimental ship back into the water.
The staff wore life jackets and hard hats, quickly climbed onto the boat. After unbuttoning the fixed cable, the airship floated towards another experimental boat.
A large number of testers boarded the No. 1 experimental ship and began to inspect the internal structure of the ship to see if there were any deformation and breakage, especially near the fixtures connecting the cables, which are the key inspection parts.
The test continues.
After a day.
They tested once every half hour on average, and tested a total of 24 gondola tasks, accumulating a thick stack of test data.
In the evening, in the canteen of Jiangxin Shipyard.
While eating, everyone discussed the test situation.
Hu Renbo, who took a sip of tomato egg soup, said with a smile: "Today's test is still in line with expectations, and everyone will continue to work hard tomorrow."
Li Guang was relieved to see that he had not tested a full-load gondola test today, but the experimental ship performed very well in five empty ship tests, five 200-ton load tests, five 400-ton load tests, five 600-ton load tests, and four 800-ton load tests.
Although the experimental ship No. 1 claims to maximize weight loss, the actual strength of the overall skeleton and hull still has a redundant amount of about 40%. If compared with ordinary transport ships, its strength is about 1.3 times.
The experimental ship V has the largest intensity redundancy, reaching about 137%, which is more than two times that of ordinary inland transport ships.
If the test is ideal, Li Guangjian naturally hopes that the No. 1 solution can pass the test, because this solution has the lowest cost and the largest payload.
Duan Guohua picked up a bowl of soup and said to Hu Renbo: "Team Leader Hu, we still have work tomorrow, so we won't drink anymore. I will use soup instead of wine to congratulate us on our smooth work."
"Okay!"
After eating and drinking, everyone did not rest, but began to organize today's test data and prepare to integrate it into a test report.
The next five days.
Near Jiangxin Shipyard, airship No. 3001 has been flying around.
The test results finally came out.
In the office, Hu Renbo looked through the test data and showed a smile on his face: "It seems that the overall strength of your company's experimental ship is very good. Even the lightest experimental ship, the lightest hull, has withstood full load tests and overweight tests."
"Happy and happy together." Li Guang finally felt relieved when he saw this.
Duan Guohua was also very surprised at the performance of the new material: "Yes! I didn't expect that the new ship is so strong. Even if it is overweight 500 tons, it can still rebound and recover quickly after slight deformation."
Li Guangjian reminded: "But overweight is definitely not suitable. I do not recommend overweight transportation. This will not only lead to increased power consumption, but also repeatedly distorting the hull structure, which will cause material fatigue in the hull, which will make the hull worse."
"I understand, I will record this specifically." Hu Renbo didn't want to be implicated.
If any owner who wants money and lives is desperately overloading, causing the strength of the transport ship to decrease and finally something happens during the gondola, he may be implicated.
Therefore, such matters must be reported and the ship owner is mandatory to transport according to the standard load load of the transport ship.
Although Hailufeng Company's own transport ship must abide by the rules, it is unknown whether the operators of other transport ships will abide by the rules.
After all, the overloading situation in the domestic transportation industry is very serious, especially in the road transportation industry, where overloading situation is as common as it is.
Inland transport also has overload conditions. After all, compared with various sea transport with very strict requirements, due to the calm river surface of the inland transport, many ship owners have a lucky mentality and feel that there is no problem with overloading.
However, as an inland transport ship that can be transported in the air, overloading is absolutely not allowed, otherwise it will cause the hull structure to decline and it is easy to cause safety hazards.
Li Guangjian flipped through the test report: "Captain Hu, will we continue to test next?"
Hu Renbo nodded: "We must continue to test, but we are not testing at the factory. The company has arranged it. A week later, a gondola test will be conducted between Ganjiang and Beijiang. This time we will have to be fully loaded with goods for actual testing."
"Then do we need to send people?"
"It is better to send some technicians. If there is an emergency, we need to repair and adjust on site."
Li Guangjian also felt that it was necessary to send people to follow: "No problem, I will tell the general manager that 10 related technicians will be sent to follow."
"Okay."
After they sorted out all the materials, they sent them to the company.
In fact, Jiang Miao, Wan Gaofeng and others are also paying attention to this matter these days.
After receiving the internal test report for this test, Jiang Miao carefully looked through it and found that the overall operation of the new ship cooperated with the airship was pretty good.
If it is transported at a low altitude or close distance, the transportation distance is within 10 kilometers, the total cost at one time is about 300 to 500 yuan, and a trip takes about half an hour, and you can transport it up to 48 times a day.
This is much faster than the lock.
After all, it takes about an hour to pass through the locks at a time.
