Rise of the 1630s South America

Chapter 2108 Technical Reserve ([-])

"In terms of general structure, there are still some differences between iron boats and wooden boats." In the night school of Dayuhe Naval Shipyard, the gas lamps were shining brightly and dazzlingly. Chen Xiaomao sat in the first row, listening with half understanding. Following the lecturer's explanation.

Outside the auditorium used as a classroom, several heavily armed factory security guards stood outside the door, imitating idlers and others approaching and eavesdropping.A special agent from the Statistics and Investigation Bureau of Syphilis Patients was hidden in the shadows in the corner, smoking a cigarette while quietly thinking about something.According to past experience, when the night schools of the major state-owned enterprises on the east coast start their lectures, there are always some dubious and suspicious elements approaching, and the existence of security guards and secret agents is precisely to deal with these guys.

Evening classes usually start at 07:30 after dinner and end at 09:30, a total of two hours.The content of the lectures is generally formulated by each factory, but basically it is related to the production content of the factory. Among them, there are general courses such as machinery and transmission, which are unavoidable for all mechanized chemical factories. Basically, they will be taught. The difference is the depth. To varying degrees.

In addition to general courses, each factory will also teach some special content according to their actual situation.Take Dayu River Naval Shipyard as an example. Recently, the factory has been teaching the difference between iron ships and wooden ships. The content is relatively simple, but it goes without saying in terms of explosiveness. It is definitely an epoch-making course.Because of this, when the teachers invited from Nanzui Xuefeng Lake Shipyard gave lectures, almost all the aspiring regular workers in the whole factory came, so that there were not enough seats in the auditorium, and some people simply sat on the floor , Not too dirty, concentrate on listening to the class.

"First of all, the wooden boards that make up the hull of a wooden boat cannot be connected end-to-end. Many of you here are experienced shipbuilders or craftsmen. You should know that when building a wooden boat, in order to ensure the continuity of the hull, we will stagger the adjacent The end of two planks, this structure is undoubtedly unable to withstand the stress and tension of large waves, especially when the keel of the ship is spliced." The teacher stood on the podium and talked eloquently: "Of course I know You also have many solutions, such as trying to choose a keel with a permeability ratio as much as possible, such as using high-flexibility wood as much as possible, but this will undoubtedly greatly increase the cost of shipbuilding. Especially for the keel, which exceeds 30 meters and is still It is not easy to find a transparent and straight keel. Our country is rich in forest resources, but it is not easy to find a whole keel that can build an 'Executive Committee' class three-deck battleship, right? Otherwise, we would not have spent a lot of money to transport a keel that the Courlandians got from the Congo River. Not to mention, to some extent, these can be used to make giant keels Big wood is a non-renewable resource, they will only become less and less in the forest, more and more difficult to find, and the price is getting higher and higher, so high that the shipbuilding industry cannot afford it. Therefore, as an honorable shipbuilder , Should we seek a breakthrough in this regard? There is no doubt that the focus of the breakthrough lies in the iron ship construction technology!"

After speaking, the teacher started drawing on a temporary blackboard.He drew a sketch of the keel of a ship, including the dense ribs connected to both sides of the keel, and also drew some force conditions, which basically clearly showed the situation of a ship sailing at sea.

"What is the advantage of an iron ship?" The teacher drew a chalk on the side of the ribs, asked himself and answered: "The advantage of an iron ship is that if the outer shell is made of iron plates, the distance between the iron plates It can be riveted together with rivets. In this way, the ship plates can be connected end-to-end, some defects on the hull can be overcome, the degree of water leakage of the ship will be reduced, and the ship can be made longer and larger, because the ship The hull can withstand greater forces without problems. We discovered this advantage when we built an all-steel hull in Xuefeng Lake, and passed various wind and wave tests. superior position."

"As one of the best established manufacturers on the east coast, your factory has recently purchased some technical patents related to iron ships from Xuefeng Lake Shipyard and the Engineering Institute. In the future, it will also be involved in the construction of horse iron ships." The teacher said with a smile: " There is no doubt that the iron ship represents the future. If the ship wants to grow bigger and bigger, it is not advisable to search for tall and straight logs in the forest like a haystack, and it cannot be sustainable. There is and only iron ship technology. It is the only way to solve the above problems and lead us out of the resource dilemma. Of course, at this stage, there are still some technical difficulties in the construction of iron ships, and we are also working hard to solve them. Moreover, from the economic point of view, Wooden boats still maintain a relatively high level of competitiveness, especially on small and medium-sized civil ships. I do not deny that the competitiveness of iron ships is slightly insufficient. The main problem is high cost and troublesome maintenance. Classmates! I hope that the construction of iron ships can make breakthroughs in the future. It is best for each factory to spend more energy investing in research and development, and make it truly a future product, not just a technology Reserve, and research without pain or itching, it is bound to be abandoned by the times, and the factory will also fall into an irreparable predicament because of this huge decision-making mistake."

In fact, there is no need for the teacher to emphasize so much. The four major domestic shipbuilding yards on the east coast (Dayuhe, Zhenhai, Hyundai, and Pacific Ocean) have basically introduced relevant technologies from Xuefenghu Shipyard and the Engineering Institute, and set up special projects. group for development.And this was actually completed under the leadership of the Ministry of Communications, because with the strength of the Xuefeng Lake Shipyard, it is not easy to study this step. If you want to speed up the research and development progress, it is obviously not possible to cherish your own broom. Several giants are deeply involved, so that it is possible to make a rapid breakthrough.

The first to introduce related technologies was actually the Hyundai Special Ship Factory located in Zhenhai County.The factory focuses on the production of various special-type ships, and sometimes takes orders for warships. It has strong technical force and strong determination in research and development.After the establishment of the project, the factory improved the connection between the external ship plate (iron plate) and the internal ribs by mobilizing elite soldiers and generals for research, that is, they bent the iron ribs outward to form a series of iron plates that could accept the external iron plate. The "base" of the ship's plank.This connection method of the inner and outer ship plates is simpler than the original design of Xuefeng Lake Shipyard to fill the parallel liner between the outer ship plate and the inner ribs to improve the riveting progress, and the processing method is simpler, and the riveting precision is also higher. Even less likely to "bounce".

The Pacific Shipyard on the Chilean side also contributed to the technology of iron ship construction.Through recalculation and demonstration, the factory designed a variety of angle irons and channel steels connecting various parts of the ship, and then their technicians took these design drawings to Heishan Industrial Company, Tieling Heavy Industry Complex, and Pingan Coal and Steel Complex to seek Technical support, and finally processed its production.Since then, the bending moment resistance of many components of the iron ship hull has been greatly enhanced, and the demand for parts can be reduced during manufacturing, which is of great significance for reducing the construction cost of the ship and improving its reliability.

"Our factory has been busy with relocation a while ago, probably because we don't have much energy to study iron ships." While listening to the teacher's lecture, Chen Xiaomao thought to himself: "I have been here for a few months, anyway, I I haven’t seen any part of the factory area specially reserved for the research and development of iron ships, nor have I seen any iron keel ships under construction. The group of factory leaders must have been raised for their mouths. Constant warship manufacturing orders, ship maintenance business with high profit margins, they can lie down and make a lot of money every month, probably they don’t have much energy and passion to run the research and development and construction of new ships? It seems that, The business is too good is also a problem, there is no motivation to develop new things. Alas, our factory is now the number one in the country in the construction of sailboats every year, and the proportion of new gadgets such as special ships, all-steam ships, and iron ships is too low. If things go on like this What should I do? This Xuefeng Lake shipyard is really interesting. I have only heard of their factory name before, but I don’t know where it is. Now it seems that they have made so many things quietly. , Oh, it’s really impressive.”

Chen Xiaomao's reverie didn't last long, because the teacher who took a break for a while began to talk about the force between the various parts of the iron ship, and why the hull was designed in this way and why it was built in that way. A lot of mathematical knowledge, which made Chen Xiaomao very disappointed, because he only had elementary school education, and his knowledge was limited. He avoided talking about the place and only gave a general introduction, which aggravated his doubts. At the same time, he hated his weak knowledge system and wondered how to improve his knowledge level.

There is no doubt that in this day and age, any knowledge comes at a price.This price can be money, or something else, in short, it is difficult to pass it on to you for free.Chen Xiaomao also understands that he is actually lucky enough to be able to sit in the brightly lit night school of Dayuhe Shipyard and get in touch with things that others dare not even imagine. He can touch the planet in a workshop equipped with a large number of cutting-edge machines. The top craftsmanship in the shipbuilding industry, but he is still very dissatisfied!Yes, just not satisfied!Thinking about those designers who have mastered a lot of knowledge, they are treated like stars and moons wherever they go, but I can only stand alone as the background. sad!

The teacher also said that iron ships represent the future.A wooden boat cannot be built hundreds of meters long, but an iron boat can definitely!Chen Xiaomao imagined that if he could participate in the design and construction of an iron ship in the future—well, preferably more than 20 tons, and [-] tons is not too much—and take it to travel across the Atlantic Ocean and even the Indian Ocean, That is really a beautiful thing!If there is such a day, even if my life span is reduced by [-] years, I am willing!

However, all of this requires knowledge, a lot of knowledge, how can I learn all this by myself?Chen Xiaomao has never been so eager for high-end knowledge such as mathematics, mechanics, and materials science.I have to think of a way, I can't just hang around like this!For your dream of iron boat, you have to work hard from now on!
