Open an aircraft carrier to fight against Japan

Lin Yuan didn't return to Fengtian until everything was settled properly. He was afraid that Shen Wanqing would blame himself again like in Vladivostok, so he didn't tell him his real whereabouts. He only said that he had gone to inspect the troops, and Shen Wanqing didn't ask carefully. When Lin Yuan was left alone, he thought about the Japanese ship, and the more he thought about it, the more strange he felt.Two days later, Lin Yuan asked someone to send him the photos taken during the surveillance. After seeing the photos, Lin Yuan suddenly realized, picked up the photos and came to the arsenal.

After Lin Yuan went in, he found a room at random, and saw that the people inside were busy drawing design drawings, with rubber and pencil shavings all over the floor, and a few T-squares messily placed in the corner, Lin Yuan went in and asked: "Are the experts here?"

The people inside were all young engineers on the Beijing ship. They all knew Lin Yuan, so they all stood up and said hello. Lin Yuan walked to the crowd with a smile, and jokingly said, "Why are you in such a mess here?"

A young girl blushed and went to get the broom next to the wall, and said embarrassedly: "Today is my duty, I was busy checking the strength so I forgot."

Lin Yuan then asked, "Is Yan Siming, the mechanical expert, old?"

The girl said: "Teacher Yan went to hold an expert meeting, and it's in the conference room of the arsenal."

Lin Yuan asked: "Expert meeting? What is that?" The girl smiled and said, "It's the experts in various fields who tell the progress of their fields at the meeting to see if others can use it. We here every week There will always be a meeting like this.”

Lin Yuan nodded, came out of the room, came to the meeting room, gently opened the door to go in, and saw Yan Siming dancing on the stage and saying: "Our high-precision gear technology has made a new breakthrough, Lao Liao, If you're going to build a gas turbine engine, you don't have to worry about the fuel pump having no gears."

In an aviation gas turbine engine, the fuel supply to the combustion chamber needs to provide a high pressure to the oil. These pressures are provided by a pump composed of gears. The gear set is connected to the main shaft of the engine through a series of structures, and the main shaft drives the rotation. .

The sound of Lin Yuan opening the door made everyone turn their heads. When they saw Lin Yuan, they all laughed and said, "Why is Comrade Xiao Lin here? Is there something wrong?"

Lin Yuan shook his head again and again, and said, "Let's talk first."

Yan Siming smiled and said, "We've finished talking, you should talk about your business."

Then Lin Yuan walked up to the stage, turned on the projector, and put the photo under the projector. A clear image of the photo appeared on the big screen. Lin Yuan pointed to the photo and said, "This is the new type of Japanese high-speed ship I discovered. , They use this kind of ship to transport drugs to our country, I felt a little strange when I first saw it, I don’t know if everyone sees the strangeness?”

Wan Ling, a ship expert, only glanced at it and said: "The chimney of this ship is too small, it's almost like nothing!"

Lin Yuan thought to himself: "Experts are indeed experts. They can see what I have been pondering for several days with just one glance." Why is your chimney so small?"

Wan Ling frowned, thought for a while, and said, "Is it because of the angle of the photo?"

Lin Yuan smiled and said: "In my opinion, it is the Japanese who installed a new type of power system on the ship. I suspect that this power system is an internal combustion engine!" Machinery, one is power electronics, mechanical experts have more or less heard of internal combustion engines, but power electronics is different, they are all at a loss when they hear the term "internal combustion engine".

Liao Ming, an aviation engine expert, said with a smile: "The internal combustion engine, as the name suggests, means that the combustion of fuel and work are carried out inside the machine. The opposite is the external combustion engine. Extensive steam engines."

"Internal combustion engines can be divided into reciprocating and rotary types according to the movement form of the working parts. The rotary type is our gas turbine, such as an aero engine, and the reciprocating type is like gasoline engines and diesel engines commonly used in automobiles and tanks. They are used on ships and military ships. Gas turbines are generally used, while most civilian ships use diesel engines."

After what Liao Ming said, everyone turned to Sun Yunchao, an expert in diesel engines and gasoline engines. He is also an academician of the Chinese Academy of Engineering and participated in the design of the power system of the third and fourth generation main battle tanks. The designed diesel engine and its various modifications are used in almost all armored vehicles of our army.

Sun Yunchao said: "In modern times, most civilian ships use diesel engines as power, but the first time diesel engines were used as ship power was in 1904, and the prototype of diesel engines appeared in 1898, so I think this Japanese A ship, most likely powered by a gasoline engine."

"Compared with the original steam engine, diesel engine and gasoline engine have advantages in small ships because of their light weight, so the speed of this ship will definitely not be slow." Lin Yuan said: "Yes, this is also my The purpose of my second visit is that the Japanese boats are very fast, while our anti-smuggling boats were all eliminated by foreign devils. When I rescued the Chinese laborers, I couldn’t catch up with the American devil’s boats, and now it’s even more impossible to catch up with the Japanese. It is a human boat, so we must use the latest power! That is the diesel engine!" Sun Yunchao said with a smile: "Great, we are finally going to build a diesel engine. With the diesel engine, we can build tanks and high-power loads. car."

Lin Yuan smiled and said: "You are right. Diesel engines are simply catalysts for industrial development. You can think of it this way. With diesel engines, we have an advanced power source. In this way, we can produce a large number of agricultural products. Machinery, just as we are reclaiming the Great Northern Wilderness, with advanced agricultural machinery, I believe we will be able to solve the food problem soon!"

"With diesel engines, we can also manufacture a lot of construction machinery, such as multi-bucket excavators, rock drills, concrete mixers, etc. These construction machinery can double the time for us to build hydropower stations and docks. This is the time for us to dominate the world!"

Everyone smiled knowingly when they heard this. At this time, metallurgical expert Liu Jinqiu said: "But we have a lot of materials that we can't make out now! What we lack most now are various elemental ores. The characteristics of alloy steel are like this. When a certain element is missing, the performance is not good!"

Sun Yunchao said with a smile: "It doesn't matter, we can build a simple diesel engine, and the parts in it are all made of the materials we use now. I think there is no problem. When we start to mine various ores on a large scale, we can re-produce a batch of high-quality diesel engines. of."

Lin Yuan said: "I know that many ores are not available in the Northeast, so they have to be transported from all over the country. However, transportation is really underdeveloped. Once our various transportation facilities are ready, we can transport them from a large scale across the country."

Sun Yunchao smiled and said: "We have been preparing for the manufacture of internal combustion engines for a long time. Don't worry, if all parts cooperate fully, we will only need about ten days to make the first batch of internal combustion engines."

Lin Yuan smiled and said: "We not only need to build diesel engines, but also apply the same technology that every traveler must have on it."
