Rameau returned to his home country full of expectations. Before leaving, Li Guang gave him a suggestion, he must follow the leader of the Spanish rebels, Francisco. Franco. Li Guang only knew in later generations that the Spanish Civil War was actually a proxy war, a rehearsal for World War II. Among them, the anti-fascist front, led by the Soviet Union, supported the political axe army, while Germany and Italy supported the [***] army. And the leader of the [***] army, Francisco. Franco eventually won.

Li Guang didn't want this benefactor to die in the civil war, you must know that the Spanish Civil War was famous for the torture and killing of prisoners of war in later generations.

After sending Ramo away, Li Guang immediately threw himself into the great cause of torpedoes, and he still can't take care of the submarine, and the funds are not enough. You must know that it is now the middle of March of the 37th year, less than four months before the full-scale outbreak of the War of Resistance against Japanese Aggression.

In terms of business management, Li Guang hired the Jewish accountant Arthur Brown. Kohlberg is the plant manager. This is also what Rameau solemnly recommended when he left, Arthur. Kohlberg has worked for Ramo for more than 10 years, and he is absolutely shrewd and capable, not only very expert in factory production management, but also very familiar with Uruguayan society, and can help Li Guang deal with everything in terms of political axes.

All this is what Li Guang urgently needs, Li Guang doesn't look at the family business, but in fact he is just a technician, and he is not good at management or anything. So Li Guang and his workers immediately plunged into the improvement and research and development of torpedoes.

After being busy for more than half a month, Li Guang really found that his level was really not qualified. Li Guang did not improve much in the development of the torpedo, he just wanted to add a simple guidance, but when it was implemented, he found out. Even the simplest magnetic guidance was extremely difficult, and all the materials used in the torpedo had to be changed to stainless steel or aluminum alloy, which was simply an impossible project, and this work had to be suspended.

Li Guang had never touched torpedoes at all in later generations, and it was difficult for him to put forward the opinion of the construction surname except for knowing a few terms. As for what guidance should be used for torpedoes, he has no idea until now. Missiles have laser guidance, infrared guidance, and customary guidance, but he really hasn't heard of any mature guidance methods for torpedoes.

In the scope of his knowledge, in addition to being able to think of magnetic guidance, it is difficult to create a guidance method, is it a remote control method? (In fact, there is a kind of wire control, but in the modern concept, this simplest and most direct way has been passed by Li Guang.) ）

The guidance method is not the most urgent for Li Guang, but the most headache for Li Guang is the lead-acid battery that he thinks is not difficult.

The technical content of manufacturing lead-acid batteries in modern society is not high, but almost every link in this era is extremely difficult. In order to be able to smoothly manufacture suitable lead-acid batteries, Li Guang had to tackle key problems one by one.

The building had to be expanded again and again, and by the end of May, when the first battery was produced, the shipyard had doubled in size. There are twelve more workshops, which is equivalent to twelve branches. Different raw materials and components are produced separately.

In modern society, under the strict social division of labor, the production of lead-acid batteries is, to put it bluntly, assembly. And now Li Guang except for a few standard parts that can be purchased from outside, ninety percent of the components are produced by himself, and the high cost of the batteries created is unimaginable for a modern person. The lead-acid battery, which is not high-end, actually costs nearly five hundred dollars a ton.

In just these twelve workshops, at least 30 technologies are used, which is a pioneering achievement for this era. After this research and development, Li Guang really realized the gap between the times, and often a technology that he didn't put in his eyes at all turned out to be a difficult point in this era.

Li Guang even judged that if all the 12 main links of his factory were not leaked, it would be difficult for other countries to imitate even if they got battery samples. In the few months that Li Guang lived in Uruguay, the people here did not seem to be so interested in this industry, and the European immigrants seemed to have a higher interest in light industries such as the food industry. Even for an industry like shipbuilding, which can be used as a pillar, it has not shown the enthusiasm it deserves. Perhaps it is because there is so much produce, these people don't have to make money through hard mental work, just shipping agricultural products to the world is enough for them to live a rich life. However, whether Uruguay has universities and technical schools, it is not difficult for Li Guang to recruit skilled workers.

Having said that, Li Guang also consciously took some confidentiality measures for each section, such as workers in different workshops are not allowed to work in tandem, and several Chinese technicians he recruited are also separated from each other to manage a section of the process.

By the end of May, the shipyard had sixty-five employees. However, the production of batteries could only reach the level of less than half a ton per day, and the progress of torpedoes was very fast after Li Guang gave up on making significant improvements. (The housing is made of aluminum alloy.) ）

In this process, Li Guang realized that Ramo's one or two decades of research was really powerful. Some time ago, when Li Guang saw Ramo's achievements, he thought that he was not advanced enough. But when he actually started machining these parts, he realized that Ramo had almost done it to the limit with the existing conditions. No wonder Rameau is so confident that his products will sell well in the event of a war. He is willing to sell his property cheaply, not because he is stupid and will not do business, but because he is confident in his products. Li Guang was only accustomed to the exquisite appearance of modern industrial products, and felt that the parts of the torpedo were too rough, but when he actually made them, he found that the accuracy of the machine tool that Ramo bought was also like this. And these machine tools turned out to be the most advanced machine tools in Germany, Switzerland, and the United States.

Li Guang could only secretly call lucky, he really picked up a treasure.

By the end of May, thirty 533mm torpedoes and ten torpedo tubes were already in possession. Now these thirty torpedoes will be ready for use just as long as the batteries are installed.

Over the course of a month in June, Li Guang conducted several tests of the torpedo and found that his battery was only twice as capable as Rameau, far from quadrupling as expected. And the performance of this torpedo has been significantly improved, and it can reach a range of three kilometers at a speed of thirty knots, which is a full double the range of the torpedo made by Ramo. And because the shell material is made of aluminum alloy, the charge is increased to three hundred kilograms, and this charge is probably not enough for the cruiser to withstand one. The last few battleships are also gameover. The destroyer, if hit, is absolutely shattered.

Li Guang judged from experience that under the existing technical conditions, with the improvement of the technical proficiency of the workers, the improvement of the details of the battery can at least increase the efficiency by half, and by that time, the firing range of this torpedo will reach 4.5 kilometers, and if the motor can be further improved, the speed can also be accelerated, and the combat effectiveness will undoubtedly be greatly improved.

In the course of the experiment, Li Guang also discovered a defect in the torpedo, and the trigger fuse used by Ramo often had problems, and Li Guang once again turned to technical research. Li Guang's hard work is even more diligent than that of the university entrance examination back then. While reading books and checking information, I was doing experiments at the same time, and I was busy in the dark. But even so, due to the limitation of knowledge, Li Guang was not able to raise the reliability of the fuse to 100 percent. For this reason, Li Guang added three fuzes to the torpedoes, which basically solved the problem of reliable fuses.

There is no big mistake in being careful, this is Li Guang's creed. In order to keep the torpedo secret, Li Guang made a slight change in the torpedo and added a timed detonation device, which automatically detonated within half an hour after the torpedo was fired, so as to prevent the torpedo's fuse from being captured and cracked by the Japanese army after it failed. Li Guangke is very clear about Xiao Yueben's copycat ability.

In the extremely intense work, time flies, and before you know it, it is already the middle of June. Seeing that the time for the outbreak of the Anti-Japanese War was approaching, Li Guang only had 45 torpedoes on hand.

Li Guang could no longer wait at this time, China's all-out war of resistance against Japanese was fought on July 7 of the 37th year, and the Battle of Songhu in Shanghai was fought on August 13. If the torpedoes could not be sent to China before 13 August, it would be a waste of Li Guangxiao's efforts for half a year.
