Chapter 269 New Ship (Ch 828095651)

Gan Province, northern part.
On the south bank of the Yangtze River, the rising sun reflects on the surging river, creating sparkling golden waves.
The Jiangxin Shipyard in Hukou County started a new busy day in the cold wind.
On a dock production line previously used to build fiberglass reinforced plastic ships, the construction of an inland transport ship similar to the 2,000-ton class has been completed.
Li Guangjian, the designer responsible for designing the ship, and Duan Guohua, head of the construction team, were chatting quietly on one side of the dock.
“Old Duan, have all the supporting facilities been installed?”
“It’s done.”
Looking at the gray-white hull in front of him, Li Guangjian looked worried: “Have the strength tests of various parts met the standards?”
Duan Guohua was very calm: “Don’t worry! Designer Li, these are new ships for testing new materials, and the money is paid by Hailufeng Company, so we can just relax.”
Because Hailufeng Company launched 5 ships at one time as an experiment.
Because it uses a composite material based on silicon bean silk, it is very light and has a very high overall strength, so the overall weight can be reduced.
Generally speaking, inland transport ships can be divided into five systems, namely: hull structure system, power system, electrical system, outfitting system, and ballast water system.
The power system and electrical system of electric transport ships, which are becoming increasingly popular, can actually be combined into one electrical system.
The four systems of an electric transport ship each account for a proportion of the ship’s weight: 55% of the hull structure system, 30% of the electrical system, 8% of the outfitting system, and 7% of the ballast water system.
After adopting new materials, the hull structure system, outfitting system and ballast water system can be lightened to varying degrees.
The five experimental transport ships they are currently building have adopted five different weight reduction solutions.
Plan 1, 52% overall weight loss;
Plan 2, 45% overall weight loss;
Plan 3, 42% overall weight loss;
Plan 4, 37% overall weight loss;
Plan No. 5, overall weight loss 34%.
Obviously, plan No. 1 is an extreme weight reduction plan, which will reduce the weight of the parts to the maximum extent possible.
The ship built with this plan is the one Li Guang saw before him.
According to their current estimates, the experimental ship of Plan No. 1 has a deadweight of about 360 tons. When fully loaded, it can carry 2,390 tons of cargo, which is about 390 tons more payload than ordinary electric transport ships.
“Old Duan, I know that the company does not need to bear any losses in building these experimental ships, but I am worried that they will not pass the tests.” Li Guangjian was feeling uneasy.
Duan Guohua patted him on the shoulder and consoled him, “It’s no use thinking about it here. We should launch these five experimental transport ships as soon as possible. The airship will arrive tomorrow.”
“Okay! Hope everything goes well.”
Under the gaze of the two.
Five experimental transport ships completed their launching ceremonies one after another. Since they were experimental transport ships, the shipyard did not make a big fanfare.
After entering the water, testers began to check whether there were any leaks inside.
The ballast water system test then began.
From testing in the morning to sunset in the evening.
All systems are working well.
In fact, this is very normal, because in the past six months, Jiangxin Shipyard has built a total of 17 electric inland transport ships and accumulated a lot of experience.
Various problematic supporting systems have also been improved one after another.
At present, the electrical system of electric transport ships is already very mature. With this relatively mature supporting system, major problems will basically not occur.
Looking at the preliminary test report in his hand, Li Guangjian breathed a sigh of relief: “Ship No. 1 is fully loaded with 2,390 tons, and there is no deformation of the frame and hull. I can sleep well tonight.”
Duan Guohua smiled and comforted him: “I said it’s not a big problem, Designer Li, just relax!”
“Old Duan, let’s go eat first! We have a lot of things to do tomorrow.”
“good.”
No words were spoken that night.
It was early in the morning, just as the sky was getting light.
Fine snowflakes began to fall over the shipyard.
After having breakfast, Duan Guohua, Li Guangjian and others stood at the dock near the shipyard, looking towards the northwest.
There were dark clouds and snowflakes falling from time to time.
“Hu…” Duan Guohua exhaled white air and rubbed his red, frozen palms: “The weather changes so quickly.”
“Duan Gong, have a bag of hot soy milk.” An employee was carrying an insulated foam box containing a bunch of small packages of hot soy milk and tea eggs.
Duan Guohua didn’t hesitate and took two bags. He put one bag on his hand to warm it up, and bit the other bag open with his teeth and slurped it down without spilling a drop: “Huh… It’s so comfortable to drink hot soy milk in this weather.”
Li Guangjian, who was eating tea eggs and drinking hot soy milk, suddenly stuffed the tea egg into his mouth and swallowed it with the hot soy milk: “Hey… here it comes!”
“Coming?” Duan Guohua raised his head and looked towards the northwest.
I saw a blue dot slowly flying towards this side in the dark clouds in the distance.
He quickly drank the soy milk in his hand, picked up the telescope and observed: “Well, it’s indeed here, but it’s still a little far.”
Although they now saw blue dots, that was because the airship was very large.
The Blue Whale 3, which can lift 3,200 tons of cargo, is 583 meters long, 98.6 meters in diameter, and contains 2.7 million cubic meters of hydrogen.
Half an hour later.
The Blue Whale 3001 airship slowly docked over the Jiangxin Shipyard.
Standing under this airship, the feeling was really shocking and depressing. The whole sky suddenly turned dark, and it felt as if the sky was obscured and the sun was blocked out.
The Blue Whale Airship Company had sent people over a few days ago, bringing communications vehicles, signal guidance vehicles and drone shielding vehicles.
In fact, the airship itself also has a built-in drone shielding system.
It is even to prevent some modified or homemade drones from breaking through the drone shielding system and attacking the airship.
A layer of silicon carbide nanotube woven net is specially set on the outside of the airship.
The lines of these nets are high-strength and high-hardness silicon carbide nanotubes with a diameter of 140 nanometers. From the outside, these nets are almost invisible to the naked eye unless you look closely.
These protective nets weigh only a few hundred kilograms in total, but their protective performance is very high. If an ordinary drone collides with these nano nets, it will be cut into pieces in an instant.
At the Minqin airship test site, not only the impact and attack of rotary-wing drones have been tested, but also the attacks of fixed-wing drones, mortar shells, rockets, and missiles.
The result is that drones have no way of penetrating the protective nanonet, and grenades and artillery shells fired by drones will also be blocked.
After all, this layer of protective nano-net is about 1 meter away from the airship skin, and the surface of the airship is also made of high-strength and high-hardness silicon carbide nanotube woven skin and photovoltaic panels. There is also a layer of carbon dioxide airbag inside, which is also very strong. It is obviously not so easy to break through the three layers of protection and hit the hydrogen airbag inside the airship.
Even armor-piercing shells with shaped charges cannot produce effective destructive effects.
Because this layer of nanotubes forms a protective net that can cut through shells instantly, the faster the shells are, the faster they are cut.
As for the explosion and high temperature generated at the moment of cutting, they are also useless. At most, they will cause the paint on the surface of the airship to fall off.
After all, silicon carbide nanotubes have very high hardness, and their strength and tensile strength are also very good, which can basically be compared with carbon nanotubes. At the same time, they have high temperature resistance and high thermal conductivity properties.
The armor-piercing shaped-charge projectiles designed specifically for tank armor can only scratch the surface of the airship.
And this is just the basic style.
If specialized designs are made specifically for weapons such as armor-piercing shells and rockets, such as adding several more layers of protective nets, and using silicon carbide nanotubes and aramid fibers to composite the armor with several more layers and a hollow design, metal jets will not be able to penetrate this protective system at all.
However, Hailufeng Company is not interested in this kind of product. However, several qualified domestic companies have studied many strange samples.
…
The Blue Whale 3001 airship was outfitted seven days ago and tested around Minqin for a few days before being sent here to test the crane project.
The team leader Hu Renbo, who was sent over, brought two temporary pilots and successfully took over the control of the airship from the remote control center.
Li Guangjian came over and asked, “Team Leader Hu, how is the situation over there?”
“I have taken over control and can start testing anytime.” Hu Renbo glanced at his watch: “It’s almost eight o’clock. How are you guys?”
“We’re ready too.” Li Guang suddenly became nervous again. He couldn’t change this bad habit. Whenever something big happened, he would unconsciously become anxious.
Seeing the other party’s inner uneasiness, Hu Renbo smiled and said, “Designer Li, don’t worry too much. Even if there is a problem with 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 should know that in order to verify the safety of hydrogen airships, the Blue Whale Airship Company blew up more than a dozen airships of various sizes.
The five experimental ships only cost tens of millions. Even if something goes wrong, it would 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 a product into use without conducting safety tests once it’s designed! This is obviously impossible, unless you completely imitate the mature solutions of other companies, otherwise you’d better not think about this good thing.
Since the Blue Whale airship has no manned system, it does not need to consider too much, which is why it can complete the safety test so quickly.
As for Panshi Automobile, which needs to transport passengers, it has scrapped a total of 278 experimental models since September and is still continuing various tests.
The two sides discussed for a while and then started the first gondola test.
Considering the testing process, the ship was not loaded with any cargo during the first crane test, and even the ballast water was unloaded.
A weight of 360 tons is child’s play for the Blue Whale 3001, which can pull 3,200 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 snow and wind.
By adjusting the hydrogen and carbon dioxide in the internal airbags, the airship slowly descended from a height of 100 meters to about 15 meters above.
Eight special cables were thrown down from the cable fixing rack on the belly of the airship, and the crew on board quickly fastened the cables to the specially designed fixing devices on the ship.
“It’s fixed.”
“Recheck it.”
“OK.”
Ten minutes later, the crew on board came down and everyone evacuated to a safe area.
As the pilot pressed the buoyancy increase button, the airship’s buoyancy system began to increase the overall buoyancy. Soon the buoyancy exceeded the weight of the towing 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 and then stopped increasing its buoyancy.
Hu Renbo held a telescope and carefully observed the bottom of the experimental ship. Others also held telescopes and observed as well.
Li Guangjian put down the telescope, took notes and said slowly: “There is no obvious deformation.”
“Do you want to fly a circle?” Duan Guohua turned his head and asked.
Hu Renbo nodded: “Yes, let’s fly a dozen kilometers and see.”
The pilot immediately understood and controlled the airship to fly at a constant speed along the safe area that had been cleared in advance. When it reached the end of the safe area, it slowly turned and flew back along the original route.
Then it reduced its own buoyancy, approached the water surface, and put the experimental boat back into the water.
The staff, wearing life jackets and safety helmets, quickly climbed onto the boat. After untying the fixed cables, the airship floated towards another experimental ship.
A large number of inspectors boarded the No. 1 experimental ship and began to inspect the internal structure of the ship to check for any deformation or breakage, especially near the fixing devices for connecting cables, which were the key areas for inspection.
Testing continues.
At the end of the day.
They conducted the test once every half an hour on average, and completed a total of 24 hanging boat missions, accumulating a thick stack of test data.
At night, in the cafeteria of Jiangxin Shipyard.
While eating, everyone discussed the test results.
Hu Renbo took a sip of tomato and egg soup and said with a smile: “Today’s test is still in line with expectations. Let’s keep up the good work tomorrow.”
Li Guangjian was relieved at this time. Although there was no test of the fully loaded crane today, the performance of the experimental ship was very good in the 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 Experimental Ship No. 1 claims to have achieved maximum weight reduction, the actual strength of the overall frame and hull still has about 40% redundancy. Its strength is about 1.3 times that of an ordinary transport ship.
The strength redundancy of Experimental Ship No. 5 is the largest, 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 Plan No. 1 can pass the test because this plan has the lowest cost and the largest payload.
Duan Guohua picked up a bowl of soup and toasted to Hu Renbo: “Team Leader Hu, we still have work to do tomorrow, so we won’t drink. I’ll use the soup instead of wine to wish us a smooth work in the future.”
“good!”
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 the Jiangxin Shipyard, airship No. 3001 has been flying around.
And the test results are finally out.
In the office, Hu Renbo flipped through the test data with a smile on his face: “It seems that the overall strength of your company’s experimental ships is very good. Even the lightest experimental ship No. 1 has withstood the full load test and overweight test.”
“Congratulations.” Li Guang was finally relieved after seeing this.
Duan Guohua was also very surprised by the performance of the new material: “Yes! I didn’t expect the new ship to be so strong. Even if it is 500 tons overweight, it can still rebound quickly after a slight deformation.”
Li Guangjian reminded: “However, overweight is definitely not suitable. I do not recommend overweight transportation. This will not only increase power consumption, but also repeatedly distort the hull structure, causing material fatigue in the hull, thereby reducing the hull strength.”
“I understand. I will make a special note of this.” Hu Renbo didn’t want to be implicated.
If a shipowner who values ​​money over life desperately overloads the ship, causing the strength of the transport ship to decrease, and finally something goes wrong during the process of lifting the ship, he may be implicated.
Therefore, such matters must be reported, and shipowners must be forced to transport according to the standard load of the transport ship.
Although Hailufeng Company’s own transport ships will certainly abide by the rules, it is unknown whether the operators of other transport ships will abide by the rules.
After all, the problem of overloading in the domestic transportation industry is very serious, especially in the road transportation industry, where overloading is commonplace.
Inland waterway transport also has overloading problems. After all, compared with sea transport which has very strict requirements, river transport has a calm surface, so many ship owners take chances and think that there is no problem with overloading.
However, as an inland transport ship that can be lifted in the air, overloading is absolutely not allowed, otherwise it will cause the hull structure to decline, which can easily cause safety hazards.
Li Guangjian flipped through the test report and asked, “Team Leader Hu, do you want to continue the test?”
Hu Renbo nodded and said, “We will definitely continue the test, but not at the factory. The company has already arranged to conduct a test of the gondola between the Ganjiang River and the Beijiang River in a week. This time, we will test it with a full load of cargo.”
“Do we need to send someone over then?”
“It’s better to send some technicians. If there is an emergency, we need to make repairs and adjustments on site.”
Li Guangjian also felt that it was necessary to send someone to follow: “No problem, I will talk to the general manager and then send 10 relevant technical personnel to follow.”
“good.”
After they sorted out all the materials, they sent them to the company.
In fact, Jiang Miao, Wan Gaofeng and others have also been paying attention to this matter these days.
After receiving the internal test report of this test, Jiang Miao read it carefully and found that the overall operation of the new ship in conjunction with the airship was quite good.
If the lifting is done at low altitude and short distance, the transportation distance is within 10 kilometers, and the total cost is about 300 to 500 yuan. One trip takes about half an hour, and a maximum of 48 lifts can be made a day.
This is much faster than the lock.
After all, there are many locks, and it takes about an hour to pass through each lock.
