Chapter 238 Transportation Change
Time goes back to five hours ago.
The bean silk processing laboratory of Wansheng Knitting Factory.
More than a dozen researchers are working hard.
Deputy Technical Director Yang Yuanzhen ran in in a hurry and shouted, "The boss is here, everyone is cheering up."
"Oh..."
"Really fake!?"
A researcher wearing glasses accidentally knocked down a bottle of boric acid placed beside him, and he came to his senses , whispered in a low voice, "Damn! You really mean it..."
"Huizi? What's wrong?" Yang Yuanzhen frowned.
Kou Hui, wearing glasses, shook his head and replied with a dry smile: "Nothing."
"Be careful, the boss attaches great importance to this kind of thing. Don't let it go at critical moments..."
At this moment, the assistant manager ran over and whispered a few words in Yang Yuanzhen's ear. He was relieved. In one breath, but he didn't take it lightly. After all, the boss's actions were not something he could decide, so he could only continue to instruct: "So keep doing things and follow the procedures of the laboratory safety manual."
"I know ”
Kou Hui buried his head in dealing with the mistake just now and quickly dispose of the dumped boric acid solution safely, but the portions of artificial silk and artificial spider silk that were infected by the boric acid solution must not continue Used.
However, due to the laboratory management, the reason for this scrapping must be stated. He was worried that Yang Yuanzhen would discover his mistake, so he planned to get away with it.
He pretended to deal with these artificial silk and artificial spider silk, using the direction of boric acid as an excuse to conceal the matter.
As the experimental research continued, Kou Hui frowned and he discovered a very strange situation.
The artificial spider silk that was stained with boric acid had a change, and this situation caught him off guard.
When he went to eat mayu spring fried rice noodles across from Tengfei Road, he was a little uneasy.
Another researcher took a sip of Coke: "Huizi? Why is he looking distracted?"
"Nothing, I'm thinking about an experimental question." Kou Hui certainly wouldn't tell the other party about his experiment. After all, such a thing can be big or small. If the other party makes a report, it will be more than worth the loss.
In the afternoon, he took some samples and sent them to Nanhu Research Center in packing them for a molecular-level analysis.
Because I couldn't figure out what this special change was, Kou Hui did not report it, but continued to replicate the morning's research.
He not only took artificial spider silk, but also used the yarn and silk cloth of artificial spider silk for experiments.
When dealing with silk and yarn, no obvious problems were found, but when it came to the silk cloth, he discovered a situation.
"It's actually like this?" Kou Hui murmured to himself.
He looked at the artificial spider silk cloth in front of him that was stained with boric acid. After washing the acid solution, he dried it through a dryer. It did not change much in other tests, the only major changes occurred. One thing is airtightness.
In the test, this ordinary density silk cloth has increased its airtightness many times. Kou Hui did not test it out because the laboratory's equipment is insufficient.
Kou Hui was doing related experiments for more than a week.
The silk cloth treated with boric acid has very good airtightness, especially silk cloth woven with high-voltage and special textile technology. After treatment with a specific content of boric acid solution, its airtightness is almost the same as that of a silk cloth. Reaching the ultimate.
His experimental report also attracted the attention of technical director Meng Feng and deputy technical director Yang Yuanzhen.
The two applied for electron microscopes and other experimental equipment in the headquarters laboratory and began to conduct comprehensive testing of the silk cloths.
After the results of the electron microscope detection and other detection items come out.
Everyone was shocked.
Meng Feng mentioned glasses: "Boric acid reacts with an amino acid of artificial spider silk protein to form a special nanostructure, which combine to fill the gaps of the silk cloth. ”
"No wonder the air tightness becomes so high." "Old Yang, please arrange it and let someone extract the amino acids of this special spider silk protein." "Okay, I'll arrange it right away."
In fact, there are many types of amino acids in nature.
Although there are usually only twenty-one amino acids that make up proteins, there are still many amino acids that do not participate in the composition of proteins in nature, such as various amino acids in plants.
The amino acids in this artificial spider silk protein are not protein amino acids, but plant-type amino acids of soybeans. However, this amino acid is also fixed in the soybean silk during the use of calcium peroxide solution to treat soybean protein.
The experiment continued.
As the deepening of the research, the reaction between this amino acid and boric acid solution has also been studied.
The result disappointed everyone.
The reason is that the separated amino acids, although they react with boric acid, cannot form dense nanostructures.
Of course, they are not finding nothing.
They found that this amino acid cannot form dense nanostructures alone, but can assist silk cloth to form denser nanostructures. Especially after adding glycerol as an auxiliary agent, the nanostructures formed can be almost denser. To describe it as impermeable.
The airtightness of this thing is about 7.4 times higher than that of the best commercial films with airtightness.
And even if hydrogen has very good penetration characteristics, it is difficult to penetrate the modified bean silk cloth.
The weight of the modified bean silk cloth is not high. On the premise of ensuring its airtightness, the weight of this material per square meter is about 160 grams to 190 grams.
For example, the minimum standard of 160 grams is still about 3.9 times that of current commercial products.
If this thing is used as an airbag to store hydrogen and helium, the annual leakage rates of 160 grams of modified bean silk cloth are: 7/10,000 hydrogen and 3/10,000 helium.
If a 190g grade modified bean silk cloth is used, the annual hydrogen leakage rate will be only 5/100,000, and the annual helium leakage rate will be only 1/300,000.
The purpose of this thing is, in addition to being a storage container for gases such as hydrogen and helium, its biggest purpose is to be an airship airbag.
For the aircraft, the weight of each component above is very important, because every kilogram of weight is deducted from the component, it means that the payload of the aircraft increases by one kilogram.
Another benefit of modified bean silk cloth as an airship airbag is that it has very good strength and elasticity, which can basically reach about 3 times that of carbon fiber, which can prevent the airbag layer from requiring too many composite layers and be in place in one step.
In addition, the modified bean silk thread can replace the tethered cable of the airship; if combined with other materials, it can also be used as the skeleton and skin material of the airship.
It is estimated that the airship's airbags, skins, skeletons, and cables can be buckled by about 50% of the weight.
Take the Flying Whale LCA60T airship that cooperates with Gaul as an example.
The maximum load capacity of the airship is 60 tons, the maximum take-off weight is 200 tons, and the dead weight of the airship reaches just over 130 tons.
In addition to motor systems, personnel support systems, instrument systems, etc., which are difficult to deduct, other skins, skeletons, airbags, cables, etc., occupy about 100 tons. In other words, if the bean silk material is used in full swing, the dead weight of the Flying Whale LCA60T airship can be compressed to about 80 tons and the payload can be increased to about 110 tons.
If helium is changed to hydrogen, its payload can be increased to 126 tons under the premise that the airbag volume remains unchanged.
A payload of 126 tons can transport 5 20-foot containers and 4 40-foot containers.
As for the risk of explosion of hydrogen airships, this is actually common sense in the backward era. Now that various technologies are used to improve, hydrogen airships will basically not have the risk of explosion or fire.
For example, using modified bean silk material with high airtightness and ultra-low permeability as airbags, the hydrogen leaks by only 70,000 per million each year. This hydrogen leaks between the skin and the airbag. As long as the ventilation is carried out regularly, it is basically not A large amount of hydrogen will accumulate in the interlayer.
When the hydrogen inside the airbag does not have suitable proportions of air or oxygen, there will be no combustion or explosion.
As long as the airship is not used as a passenger carrier, it is simply used as a transport airship, or even improved to an unmanned airship, even if it explodes, or catches fire and burns, it will not cause serious personnel losses.
However, when planning a route, you must not pass through the city or important facilities.
The airship is originally very large in size, and the city will definitely not be able to be parked. If it is changed to a hydrogen airbag, considering its safety, airship parking stations can only be built in the suburbs.
The airship has many benefits, especially after its payload is increased to such a large extent and the cost-effectiveness of the airship will become very high after abandoning the non-renewable expensive helium.
For example, the built-in airbag volume of Feijing LCA60T airship is 180,000 cubic meters. If high-purity helium is used, the cost will start at 18 million yuan. It will be calculated based on the leakage of 2% to 5% every year, and helium will be replenished every year. The cost is 360,000 to 900,000 yuan.
No mistakes, one poem, one post, one content, one in 6, one book, one bar, one read!
After changing to bean silk material and hydrogen, the cost of 180,000 cubic meters of hydrogen is about 300,000 to 600,000 yuan, and 7 per thousand yuan is leaked every year. The cost of replenishing hydrogen every year is only a few hundred yuan. Just money.
The current production cost of bean silk material is about 4,500 yuan per ton. If it is mass-produced, it can be compressed to about 3,500 yuan per ton.
Referring to the structure of the Flying Whale LCA60T airship, it takes about 35 tons of bean silk material, and the material cost is 122,500 yuan.
In addition to other materials and supporting facilities, the cost of an airship with an airship of about the same specification as the Flying Whale LCA60T airship can be reduced to about 3 million.
Considering this semi-natural organic material, its service life is generally not high. It is believed that 10 years is the service life, and the annual depreciation fee is about 300,000 yuan.
If the effective flight time per year is 7,200 hours, the hourly depreciation fee is about 42 yuan. When the load is 126 tons, the depreciation fee of 0.33 yuan per ton of cargo per hour is equally distributed.
However, the actual depreciation fee is not that much, because the cost of the parts of organic materials is not high, and similar parts such as motors, instrumentation systems, and refrigeration systems, their service life can reach at least twenty About 2019.
After Jiang Miao learned about the situation in Dousi Laboratory.
He summoned several senior executives at the headquarters. "Boss! I believe there is no problem with the company's strength in terms of technology." Qin Hanming, head of the Market Research Department, stood up and said: "According to some information we have investigated, we are currently in China. The airship technology is not high, even AVIC mainly focuses on medium-sized sightseeing airships, and has insufficient technical accumulation in large-scale transport airships. Therefore, our company is likely to establish a subsidiary in airship manufacturing itself. "
< br>"There is no way. In China, it did not pay attention to airship transportation before, or there were not many serious large-scale transport airship manufacturing companies in the world." Lei Bo, the head of the battery business department, shook his head.
Gu Huaiying, head of the logistics business department, flipping through the data of the bean silk material and the airship idea of the laboratory head Meng Feng, then he raised his head: "I support this project." > "Tell me what you think." Jiang Miao asked directly.
"Boss, the current core business of our logistics business is logistics transportation, and the core method of logistics transportation is road transportation, plus water transportation assistance."
"I know." br>
Gu Huaiying continued: "In the cost of road transportation, energy consumption and tolls are the core. At present, fuel costs account for about 60% of our fuel truck costs, tolls account for about 5%, labor costs are about 15%, fixed assets Depreciation and maintenance 10%, other expenses 10%. ”
He said while writing the data on the whiteboard.
"In terms of energy consumption, we will gradually change to electric trucks in the future, and the energy costs are expected to drop to about 10% to 17%; but the tolls and bridge costs are almost impossible to reduce."
In fact, the toll of Hailufeng Company is a benefit of Green Pass. Otherwise, during normal logistics and transportation, the toll of the toll can reach between 35% and 40% of the total cost.
Gu Huaiying said seriously: "Although we can take the benefits of GreenTong in the early stage, as our company's products become more and more diverse in the later stage, such as the launch of various deep-processed products, during the transportation process, There is no way to enjoy the benefits of Green Pass.”
"It makes sense. If transportation costs cannot be compressed, it will be difficult for us to break through the siege in competition with other companies." Qin Hanming nodded slightly.
Gu Huaiying suggested to Jiang Miao: "Boss, if the cost of airship manufacturing can be compressed to such a low level, then we can build some low-altitude dedicated lines to avoid the tolls of highways and bridges, and save a lot of tolls every year , bridge crossing fees are all astronomical figures. "Boss, according to the information collected by our market research department, the average annual toll for domestic tractors is about 91,000 yuan." Qin Hanming added: "If the flying whale airship specifications of Gaul enterprises can reach 126 tons of cargo, which is about 4 to 5 tractors, and the tolls and bridge fees need to be paid in one year. It only reaches about 360,000 to 450,000 yuan. If you travel for ten years, you can buy a new airship. "
Jiang Miao of course knows that if the cost of manufacturing and maintenance of airships can be reduced, then the airship's The cost-effectiveness is indeed much higher than that of large trucks.
After all, the energy consumption of airships is very low and the speed is not slow. It can usually reach 100 kilometers to 120 kilometers per hour, and you can also take straight-line distances in the air.
The Flying Whale LCA60T airship manufactured by the Gaul Enterprise flies at a speed of 100 kilometers per hour. Under full load, it can fly 4,500 kilometers, and consumes an average of 150 to 300 degrees per hour.
In other words, if the Hailufeng Company's airship is designed and manufactured with reference to the Feijing LCA60T airship, the power consumption will be similar.
Calculated based on the limit load of 126 tons of goods, the average electricity consumption per ton of goods per hour is 1.78 kWh per hour. The technology is 1 yuan per kilowatt-hour, which means the electricity bill of 1.78 yuan per ton of goods per hour.
Add to the depreciation fee of 0.3 yuan per hour and other expenses of 0.3 yuan, the total is 2.38 yuan per hour.
Airships can fly 60 kilometers to 120 kilometers per hour, and the average transportation cost per ton of cargo is around 0.04 yuan or 0.08 yuan.
The range is 1,000 kilometers, and the transportation cost per ton of cargo is 40 to 80 yuan.
This cost can crush road transportation, and can even be compared with river transportation and sea transportation.
If it weren't for the limit on the load capacity of the airship, inland transport may not have been used as an airship. After all, the airship speed can be 5 to 10 times faster than inland transport.
To a certain extent, once the manufacturing cost and gas cost of airships are compressed, their cost performance is very high.
Although road transportation is on the highway, if the road conditions are good, it can reach hundreds of kilometers per hour. The problem is that the road transportation is hundreds of kilometers. During this period, it is necessary to go through the winding road, but the airship can fly straight to the maximum level. Saved a lot of voyage.
The speed is slightly faster than road transportation, and the range can reach thousands of kilometers at any time. There is basically no traffic jam in the low-altitude airspace. The payload can reach more than hundreds of tons, and the transportation of each ton of cargo per kilometer is possible. The fee is between 0.04 yuan and 0.08 yuan.
This performance can definitely occupy a considerable ecological niche among all types of transportation.
As for the situation where inclement weather cannot fly, this is not a unique disadvantage of airships. Aircraft, ship, and vehicles will also be disturbed by bad weather.
The problem that airship cannot be affected by strong winds during docking can actually be solved through engineering means.
For example, when building a supporting airship station, the airship can be quickly fixed with cables and the cargo handover of the airship can be completed.
Or build a super-large airship to increase the overall weight of the airship to several thousand tons, and use its own weight to increase stability.
After everyone's discussion, Jiang Miao agreed to the logistics department's proposal to develop transportation airships. He asked Gu Huaiying to prepare an airship manufacturing subsidiary, which was specifically responsible for the research and development and manufacturing of transportation airships.
In terms of talents, there are actually many relevant talents in China. At most, they can spend money to poach a group of technical personnel, especially the designers of airship structures, which are the talents that Hailufeng Company needs more.
After all, Hailufeng Company has solved most of the material problems, and similar to motors, electronic equipment, instruments, flight control equipment, etc., there are many mature suppliers in China, which is completely different from the market. Hailufeng Company needs to worry about it.
As the world's largest and most comprehensive industrial country, there are all kinds of parts suppliers. Hailufeng's airship subsidiary only needs to design a good airship, and there will basically be no major problems in manufacturing.
