"My lord, the Chinese language of the mud can be five"

When the stiff Chinese came into his ears, Tang Haoran, who turned around, looked at the person walking behind him, it was Laval, an engineer from the shipyard power plant, at this time, his brown curly hair was caressing against the sea breeze, his face was full of childlike pride, and his blue eyes flashed with anticipation, like a child expecting a reward from an adult.

"Laval, your Chinese is at a good level!"

This is true, the current special zone employs hundreds of foreign technicians, but there are not many of them willing to learn Chinese, for this reason the company and Fuzhong have to hire a large number of translators from China, the only thing that makes people happy is that perhaps for decades the church schools have not educated talents that meet the needs of China, but those schools without exception attach importance to foreign language education, they are all qualified translators after a little study, and the only place for such people in the past is to work as compradors in foreign firms, and they can't even be an English teacher. Now that there is a shortage of talents, these translations have become an indispensable part of the introduction of their own talents.

"My lord, you came at the right time, as you said, increase the number of poles of the turbine blades, its power has increased a lot, I believe that if some of the current problems are solved, it will definitely become the favorite of ships all over the world......"

When Laval talked eloquently, Tang Haoran just kept smiling, the reason why Laval, the inventor of the "impulse steam turbine", was hired was not to solve the problem of marine power, but to solve the problem of electricity, with the development of special power facilities in the future, it will be difficult for power plants using repetitive steam engines to meet the needs of the Special Economic Zone, and the only option to solve the problem is the steam turbine. Originally compared to an impulse steam turbine. Reactionary steam turbines with simpler technology are undoubtedly the better choice. However, when the UK-based company approached Parsons, the patent holder, he first refused to go to the SAR to conduct research on steam turbines, and also demanded a patent fee of £10,000 from the UK-based company, and then £1,000 a month thereafter, and in return the patent would be transferred to the company free of charge in the future.

Faced with harsh conditions, the company did not refuse, but chose Laval in front of him, compared to Parsons's "philistine". Laval, who is also an engineer, seems a little "naïve", when the company said that he would buy his patent, he first stated the problems encountered in the experiment, said that the patent was not mature, if the other party bought it, he hoped to continue to work on this research, and in the end, the company only spent 1,000 pounds to get the patent for the impulse steam turbine, and Laval accepted a high salary of 250 pounds a month to come to the Special Administrative Region to continue to work on his passion for power research. Compared with the past, when he was engaged in research alone, there are now more than ten engineers from Britain and Germany in the Steam Power Research Institute to assist him in the development of impulse steam turbines. This naturally accelerated the development of impulse steam turbines.

“…… Now that we've broken through 1000 horsepower, the same power and rpm steam turbine is more compact and lighter than a steam engine, but ......"

Laval did not hide some of the problems he was encountering now, such as the relationship between the high speed of the impeller and the vibration, which led to a series of failures, and Tang Haoran was naturally very aware of this, and in the period after 1910 in history, the Brown Curtis Company also began to enter this market, designing and building impulse steam turbines. This type of steam turbine is more compact and lighter than Parsons steam turbines, and with the same power and speed, impulse steam turbines only require half the number of stages of reactionary steam turbines.

In an impulse steam turbine, the drop in steam pressure occurs only in the static vanes or nozzles, and the steam expanding from the nozzles has a high velocity, blowing the moving blades to drive the rotor to rotate. In an impulse steam turbine, the velocity of the steam injected in the nozzle is directly proportional to the speed of the turbine, and the faster the steam, the higher the turbine speed.

Brown-Curtis's impulse turbine had much higher rotational speed than Parsons, and with the advent of reduction gears, it was possible to design impulse turbines at higher speeds, which also placed higher demands on the materials used, which was what Parsons had been concerned about from the beginning. Although impulse turbines had obvious advantages in terms of weight and size, the relationship between high impeller speed and vibration was not fully understood at the time. This led to frequent failures of the Brown-Curtis steam turbine, which eventually led to the company's demise in the early 1920s.

However, now they are obviously encountering material problems, after all, there is no high-temperature and high-pressure boiler now, and Tang Haoran naturally has his confidence in metal materials, at least he believes that his research on metal materials is enough to meet the requirements of impulsive steam turbines for material technology in this era.

“…… Rust of the blades after a long period of work, this can be solved with stainless steel,"

When watching the steam turbine work in the research room, Tang Haoran put forward his construction, and the stainless steel in his mouth was a "civilian product" - specially developed for the export of tableware to Europe and the United States, most of the tableware used in European and American countries in this era was silver, and most of the ordinary people used cheap and corroded ordinary steel knives, after the First World War, when the shiny stainless steel tableware was launched, it quickly entered European and American families, and even replaced silver tableware because it was brighter.

Compared with ordinary steel in this era, stainless steel is not only corrosion-resistant but also has the advantage of greater strength, which can naturally meet the current needs of steam turbines, and as for the vibration problem caused by high speed, it can be slowly solved in the future.

"Laval, now the power plant, but waiting for your steam turbine, you can apply for it later, try it with stainless steel......"

Compared with the use of steam turbines on the ship, Tang Haoran now attaches more importance to the construction of the central power plant, which needs a high-power steam turbine to drive the electric motor, so as to obtain sufficient power, after all, the machine has begun to study electric machine tools with independent power, although its machine tools are improved on the basis of foreign machine tools.

This means that the SAR will need more electricity in the future, and the generators powered by the steam engine in the past may now be able to meet the needs of the SAR now, but what about the future? Perhaps in a year or two, the SAR will have to solve the power problem by repeating the construction of guò, like the developed countries of Europe at the beginning of the 20th century. This obviously runs counter to the most basic principle of economic construction -- to avoid redundant construction with low efficiency and high consumption.

Despite Laval's assurances made by patting his chest, Tang Haoran only estimated and listened to it, the steam turbine is just a technical reserve, and it is good that it can be put into use as soon as possible, but the time is not yet ripe to put it into the sea, and the sea is ......

"If the Navy must be built now, I think we should think about creating a cruiser fleet with armored cruisers as the main body......"

In the shipyard, in the face of Tang Haoran's request, Shi Tenge directly put forward the most realistic statement, the establishment of the fleet did not consult Su Yueyang and others, but directly asked Shi Tengge, the ship designer, not so much to build the navy according to the needs of the task, but according to their own financial resources, of course, more important is the shipbuilding capacity.

Tang Haoran naturally understands this, and the history of the next hundred years told him that buying a ship may not be able to buy back a modern navy, maybe buying a ship is a shortcut, but in the end it is necessary to rely on domestic shipbuilding, so that is the only feasible way to build a maritime power, and even he is not willing to adopt the Japanese way, through guò to buy ships and build ships, and then gradually improve their shipbuilding capabilities. Compared with Japan, he is more inclined to another aspect of import, buying drawings, introducing technical personnel, and guiding shipyards to build warships, after all, compared with Japan, the SEZ has less than 20 years of technological accumulation.

"My lord, building a navy needs to follow the law of gradual progress, and now the government may be able to spend millions of pounds to build a navy, but where do the personnel come from? From officers to sailors, for Fuzhong, this is a blank, perhaps, the coast guard now has more than 300 people, but when loaded on a ship, it is only enough for a cruiser. ”

Although it has been almost a year since the establishment of this coast guard department, the first ship was purchased only a year ago -- a 568-ton sail training ship, and its only use, except for coastal patrols, is to train ordinary sailors, and this is the only "sea power" that North Korea has.

"It is precisely because of the shortage of manpower that the construction of the navy cannot be greedy for perfection, after all, the construction of the navy is originally a long-term project, and the more greedy you are, the more likely it is to return to the country."

After saying this reason that speed is not too much, Shi Tengge looked at Tang Haoran and continued.

"Therefore, we should be more based on reality, first solve the existence and absence of the navy, and then seek the expansion of strength!"

This is undoubtedly the only way for any country that wants to go to the sea, and it has accumulated a lot of technology through decades of accumulation. Tang Haoran, who knew that he couldn't eat a fat man in one bite, naturally did not refute Shi Tengge's question, but asked rhetorically.

"Returning to our ancestors, with the current equipment of the shipyard, if the core equipment such as artillery and steam engines are imported from abroad, then how large a tonnage of warships can we build?"

Shipbuilding capacity, this is what Tang Haoran is most concerned about.

"There is no problem with a warship of about 3,000 tons, after all, our skilled workers are all hired from Hong Kong and Shanghai, and they all have rich experience in shipbuilding, and as for the technical personnel, they are also hired from British shipyards, but ......"

After a pause, Shi Tenge looked at Tang Haoran and couldn't help but pour cold water on him.

"But I don't think that now we should build warships, maybe we can try to make torpedo boats of tens of tons or small gunboats of hundreds of tons, but if we want to build a navy, we must first buy warships from Europe, not only for naval training, but also for shipbuilding, after all, we need to understand warships first, and then we can build warships, and the most direct way to understand modern warships is to directly buy foreign warships......"
