"What about one percent tungsten?"

Yang Chao said to the screen, on the spaceship operation screen, a piece of metal immediately changed, and the luster was slightly smooth, but the data next to it immediately changed a lot, this is a piece of alloy metal, after adding tungsten, the strength under high temperature immediately increased by three percent.

"What about two percent?"

The intensity of the high temperature has increased a lot, but the change is not so obvious.

Yang Chao increased with this, and found that 9% of tungsten is the most cost-effective, and the performance improvement is not obvious when it is added up, and the performance decreases very much when it goes down.

Well, this is the high-speed steel developed by Yang Chao, and the Americans have long figured it out, but the Americans' patents are kept secret, and the ratios of various metals are not disclosed.

So Yang Chao has to explore by himself, he has established a machine tool factory, Yang Chao intends to provide the best tools to these enterprises, otherwise it is difficult to ensure their competitiveness, when the high-precision machine tools of virtue come in, and do not crush them, Yang Chao is hoping that they can earn money to continue to expand production.

In later generations, the cost of producing an alloy was quite high, and it was necessary to constantly refine it with an electric furnace for testing, but Yang Chao was much more convenient, and the spacecraft could calculate the strength of the alloy by adding a little metal content casually, so Yang Chao had already made dozens of alloys, aluminum alloys, and magnesium alloys.

Tick Tick!

The watch suddenly called, and received a telegram from Zeppelin.

Zeppelin's first new airship was finally built, and Yang Chao was invited to participate in the launching ceremony.

Two hundred meters, the aluminum alloy skeleton and skin greatly reduce the weight, but the skin is still sealed with metal wire.

The principle is that the skin is covered on the skeleton, and then a circle of steel wire is wrapped around the outside, so that the skin and the skeleton are fixed, in fact, there is no welding process, otherwise it will not be so, but the length is spread out with a 200-kilometer-long steel wire, which invisibly increases the weight.

After the application of aluminum alloy materials, the weight of Zeppelin's airship is still greatly reduced, and the load capacity is greatly increased, the weight of this airship is 80 tons, and the load is 40 tons, but it is almost impossible to continue to improve, unless the design is improved.

In addition, the airship is equipped with five state-of-the-art diesel engines, all of which are made of magnesium alloy cylinders, with a steel jacket on the outside, and the application of new materials reduces the weight of the 8-cylinder 500 hp engine to 2 tons, which is at least 1 ton less than similar products.

The most important thing is that the engine volume has been reduced to about 1 cubic meter, which allows the airship to install more engines, this large airship with a length of 200 meters, a width and a height of 45 meters each, has 8 engines installed under the cockpit, 4 engines on each side, a total of 12 engines with a horsepower of 6000 horsepower. With such powerful horsepower, the theoretical speed of the airship reached 200 kilometers and the cruising speed was 120 kilometers.

In the end, Zeppelin, after all, is much more professional than Yang Chao, a liberal arts dog, and the things designed by others have really made great progress, and in many performances, they can already be compared with the famous Hindenburg that appeared thirty years later, such as speed, the fastest Hindenburg is only 160 kilometers per hour. But there are still huge time differences, for example, Hindenburg's load can reach 363 tons, and Zeppelin's airship is only 40 tons, but this is already a huge progress.

If Zeppelin can continue to improve the design, and Yang Chao's computer helps to simulate the improvement, it will not take a few years to surpass the Hindenburg and completely improve the airship technology for more than thirty or forty years. It is believed that this will have a huge impact on the flying technology tree and deal a big blow to the development of aircraft.

"Not bad, not bad. It's so much better than my airships. ”

The cockpit of the airship is very well decorated, not to mention the hundreds of electric lights installed on the entire airship.

In the 40-meter-long and 20-meter-wide airship cockpit there are 5 premium compartments and.

At the stern of the airship, there are two huge first-class cabins, 10 meters long and 10 meters wide, with an area of 100 square meters, so that there are not only comfortable beds, but also a living room, a bathroom, and even a one-foot-thick viewing balcony surrounded by glass.

The first class cabins are lined up along both sides of an aisle of about 4 meters, with two rows of 50 square meters wide and 10 meters long, along both sides of a 4-meter aisle. With an area of 50 square meters, the second-class cabin can have suites for wealthy families to travel, as well as individual business rooms with various washrooms, toilets and even bathtubs for the giants' business trips, and high-grade rooms decorated with various books and works of art to satisfy art lovers, all four rooms have their own characteristics, and the only thing in common is luxury.

The first class cabin is a 10-meter-long and 20-meter-wide hall with 100 high-end leather sofas installed in the front to the cockpit, which is the third class of the airship, which is actually just as high-end.

Zeppelin's new airship was renovated by experts, and with the best materials, the decoration cost alone reached one million dollars, while the cost of the entire airship was only two million dollars.

Of course, the most expensive is nothing more than the aluminum alloy material that spreads throughout the airship, Yang Chao received one million dollars from Zeppelin, Zeppelin thinks it is very cost-effective, because now the aluminum production is very low, a ton of aluminum costs thousands of dollars, in the past, Zeppelin used to use dozens of tons of aluminum It also cost more than 200,000 US dollars, Yang Chao only received one million, which made him believe that Yang Chao was talking about the cost price.

With such an expensive investment, can it pay for itself?

To answer this question, Yang Chao has the most right to speak, because the airship operation is operated by him, and it can be said very clearly that there is basically no problem in recovering costs.

Because Yang Chao sold 10 VIP tickets in advance.

Two first-class VIP tickets cost $100,000 each, and those who have a first-class VIP ticket have the right to pre-book a first-class cabin on each flight, similar to an annual pass.

The first-class annual pass has been sold out so far, with the big American banker Morgan buying one, and the Baylors of the Qing Dynasty collectively buying one.

Eight second-class annual passes, each of which is $50,000, Yang Chao bought one himself, American billionaires bought six, and the last one was surprisingly bought by the German arms giant Krupp.

This surprised Yang Chao a little, the elder Krupp was known for his rigidity and frugality, and it was hard to imagine that he would be willing to spend $100,000 on a VIP ticket.

Later, Yang Chao learned that Krupp had not done it himself when he bought this ticket, but used it to invite his big customers all over the world to travel and enjoy.

These 10 tickets alone recovered the cost of $600,000, and then there was a $10,000 third-class annual pass, more than 30 were sold, and 20 were still bought by the American rich.

The rest are mainly British and French tycoons, and curiously, there is also a Japanese who bought one.

These annual tickets alone sold nearly $1 million, and then there was the cabin advertisement, which Yang Chao contracted for a year and gave Zeppelin another $1 million.

The airship airbag was printed with a big name in English, German and French, and the logo was a big Chinese-style sword and shield cross pattern, surrounded by a circle of wheat ears, the sword and shield represent the strong country, and the wheat ears represent the rich people.

On the other side of the huge airbag, five Chinese, English, German and French characters are printed with the words "China's industrialization", and the symbols are trains and ships, and the outside is surrounded by the Great Wall.

Zeppelin's understanding of Yang Chao's advertising was that Yang Chao supported the business of the Zeppelin-Yang Chao airship company, and he was secretly grateful in his heart, but what he didn't know was that within 10 years, the airship advertising business would soar to $3 million, becoming the hallmark of the most successful company in the world, and a company that did not advertise on the airship would not be the world's first-class large enterprise.

After cutting the ribbon, Zeppelin needs to prepare for a month's departure, including adding fuel to the spacecraft and filling the airbag with helium, so the airship must be transported to Dongying first, because at present, only Yang Chao in the world can produce helium on a large scale, and only there can the airship be filled with helium.

Of course, Yang Chao introduced Air Liquide's air tank production technology from France, and a large number of air tanks will be installed on the airship to support take-off and landing, but according to Zeppelin's design, the center of the airship is a main airbag, and there are sixteen small airbags around the main airbag.

Of course, you can also pull the gas tank to Qingdao to fill helium, but Yang Chao told Zeppelin a lot of difficulties, although Zeppelin didn't understand, he could only agree to go to Dongying to fill helium.

The reason why the airship has to go to Dongying is that Yang Chao wants the spaceship to do further processing of the airship, after Dongying is filled with helium, the spaceship will directly start a round-the-world voyage from Yantai, and then the first guests of the airship can go on a global trip.

For Yang Chao to produce helium, Zeppelin knows, he is also a little curious about this, because helium production is not easy, although scientists found that the air contains helium, but the concentration is very low, the entire atmosphere of helium accounted for no 1/10,000, fortunately Yang Chao's alien spacecraft is a helium fusion powership, although the fusion reactor has been damaged, but the spacecraft still has the ability to collect helium.

As for Zeppelin's suspicions, Yang Chao could only tell him that because it involved military affairs, it must be kept secret at present, and Zeppelin would not ask more.

In March, after more than ten days of transportation, the spacecraft was slowly transported from Qingdao Railway to Dongying, and sent to Yang Chao's airship warehouse.

During the day, helium filling was carried out, and at night, in the dead of night, a long probe was drilled out from under the floor of the warehouse, and the probe pierced the aluminum alloy shell, and quietly drilled into the airbag wrapped in the shell, and strangely there was no air leakage.

This probe entered the inside of the airship airbag and reinforced the riveting of the aluminum alloy keel as a support, and the riveted position looked like a rivet, but in fact, it had been welded to death with the keel, and it was impossible to see it if the keel was constantly opened.

You carefully inspected the aluminum alloy skin, repaired the weak parts of the skin, the location of defects such as cracks, and carried out a check on the engine, and conducted a simulation, and determined that the airship would not have any accidents within 100 days, and Yang Chao was relieved.

It would be a shame if his airship had an accident on its first voyage around the world, and the impact on this cause would be even more serious than that of the later Hindenburg.

But just when he was charging helium and planning to fly to Yantai and then start a voyage around the world, suddenly the German emperor had an opinion, and he sent a telegram asking the airship to set sail from Qingdao, for which he could announce to the outside world that if the safety of the airship proved to be no problem, the German royal family would give priority to taking the Zeppelin in the future.

Well, the German emperor didn't know that it was wrong, and in an inexplicable sense of self-esteem, he had to choose the departure date in the German colony of Qingdao, instead of the port city of Yantai.

Yang Chao agreed, not because the German emperor's statement could add glory to the airship, but because he felt that the German emperor's move would only cause disgust to the whole world.

On March 9, the airship carried the first batch of passengers, led by a group of Beizi and Baylor of the Qing Empire, led by Zai Zhen and Zai Ze, and embarked on a journey around the world under the pretext of diplomatic envoys.
