Open an aircraft carrier to fight against Japan

Lin Yuan went on to say: "This technology is exhaust gas turbocharging, a must-have technology for every traveler!"

Sun Yunchao couldn't help laughing when he heard Lin Yuan's words, he said: "Exhaust gas turbocharging: use the exhaust gas after doing work to drive the turbine, and the rotating turbine increases the pressure of the air entering the combustion chamber, which not only increases the power that the engine can provide, but also greatly It is indeed a good idea to greatly save fuel consumption, but the difficulty of this kind of thing is not small, and it is not something we can play now."

Sun Yunchao explained: "As the pressure of the air entering the combustion chamber increases, the heat generated by combustion will also increase accordingly, and the heat load of each component of the combustion chamber will also increase accordingly. We have calculated that if we take the boost ratio designed If it is too small, the supercharging effect will not be obvious, and the increased power cannot offset the loss of effective power caused by the weight increase after adding turbocharged parts.”

"If we design a larger boost ratio, with our existing materials, the piston top of the cylinder can't withstand such a high temperature, and the service life will be greatly reduced. Therefore, turbo increase is not available to everyone, at least we There is no way to use it now."

Lin Yuan nodded and said, "Okay then, let's not use turbocharging. After we design the diesel engine, we will use it to replace the boiler and transmission parts on the existing anti-smuggling ship." Wan Ling could not bear to hear this. He couldn't stop laughing, Lin Yuan knew that he must have made some mistake again, making him laugh at Dafang's family, so Lin Yuan asked a little embarrassedly, "Old Man, what are you laughing at?"

Wan Ling said: "Do you think that the power system can be replaced whenever you want? Diesel engines have the best operating speed point, and the continuous power is the highest when working at this speed, and the propeller also has the best working speed point. The propulsion efficiency is the highest, if the two speed points cannot match, what problems will it cause?”

"Also, when the ship is in the water, the center of gravity and the equivalent center of all buoyancy are not coincident, so try to control the weight distribution during design, so that the difference between these two points is not too far, if the difference is too far, To put it bluntly speaking, the ship will sink at one end, and it will tilt at an angle once it enters the water, which will have a great impact on the subsequent use of the ship, so the equipment on the ship cannot be changed randomly.”

"When our new gas turbines for ships came out, some people in our country said that we should replace our new gas turbines with those old-fashioned warships as soon as possible. I also wrote an article in a military magazine, explaining the difficulty of this matter. For one type of engine, the supporting transmission system and propeller need to be greatly changed, so it is not so easy to change the engine.”

Lin Yuan nodded and asked, "Then what do you think we should do?" Wan Ling said, "We will start from scratch and build a new type of maritime patrol ship."

Lin Yuan asked, "But is there enough time?"

Wan Ling said: "The manufacture of the hull is not difficult, because this type of ship is relatively small, so relying on the craftsmen of Jilin Machinery Bureau, we can manufacture it, and wait for the power system to be installed and tested before it can be used."

Lin Yuan asked, "Okay, I'll wait for your news."

Lin Yuan returned from the arsenal to the governor's office. Seeing Lin Yuan coming back, Chen Qingyun hurriedly stepped forward and said, "Shuai Lin, you are considered to be back. I have two important matters to report to you."

Lin Yuan replied: "Don't worry, take your time." Chen Qingyun said: "The first thing is: five new opium dens have recently opened in the city."

Lin Yuan nodded and asked, "What about the next one?"

Chen Qingyun said: "Shuai Lin, you can't let the opium shop stay open, this opium is a disaster for the country and the people!"

Lin Yuan said confidently, "Don't worry, I know about opium."

Chen Qingyun said: "The second thing is: the British factory has started to work, but they discarded the discarded stones at will, which caused complaints from the nearby people."

Lin Yuan thought: "The stones left over from the production of alumina from bauxite are good things for making concrete, and they must not be wasted." So Lin Yuan ordered: "You immediately send someone to collect their discarded stones. , and then build a warehouse nearby to hoard these stones, I keep them for important uses.”

Chen Qingyun nodded and said, "What about the opium?"

Lin Yuan smiled and said, "You don't have to worry about the opium thing, I have my own solution."

Half a month passed in a blink of an eye, it was already April, and the weather was getting warmer. Lin Yuan received news from the arsenal: a new type of maritime patrol ship had been built and shipped to Yingkou Port.

Lin Yuan rushed to Yingkou Port immediately after receiving the news. When he arrived, Wan Ling and Sun Yunchao were testing the new boat at the private water training ground. Yuan didn't see the battalion commander Gu Jinkai, so he asked a sailor, "Where did your battalion commander go?"

The sailor said: "I was called by Asko, the director of the taxation department, to scold me. That foreign devil took out his anger on us when he encountered a fire. It's not a thing."

At this time, the competent customs department was the Taxation Department, but the head of the department was a British. It is not surprising that after the Second Opium War, the British forced the Qing government to sign the "Sino-British Commercial Charter". The article expressly stipulates: Let the prime minister invite British (American, French) people to help with taxation, and strictly investigate tax evasion...

Because the British were the most powerful, in 1859, the British Li Taitai was appointed as the "General Taxation Department of China". Until 1863, the British Hurd succeeded the general taxation department. More than [-] treaty ports have established tax departments, and Yingkou Port is among them.Lin Yuan inquired about the location of the tax department, and walked over quickly. When he arrived, he was stopped by the British guards at the door. Lin Yuan said a few words in English to scare the guards away, and Lin Yuan immediately walked into the tax department. .

As soon as Lin Yuan went up to the second floor, he heard someone roaring in the corridor, speaking in blunt Chinese, so Lin Yuan understood immediately: it must be the director of the taxation department scolding Gu Jinkai.

Just as Lin Yuan was about to listen attentively, he saw a door on the side open, and Gu Jinkai came out angrily from inside, and asked in surprise when he saw Lin Yuan, "Shuai Lin, why are you here?"

Lin Yuan smiled and said, "I'm here to check on the quality of this director. What's wrong with you? Is there something wrong?" Gu Jinkai sighed and said, "Today they said they received a report that there were two British ships Smuggled sweaters, let us go to check, but the British ship is too fast, we can't catch up at all! Its ship is still out of range of our machine guns, so I have to come back and report that it has not caught up."

"Who knew that the director would scold me for half an hour without asking indiscriminate words! If I'm wrong, it's fine. The British gave this anti-smuggling boat. Now their boat can't keep up with others, and he actually scolded me for being incapable. Are you angry about this matter!"

Lin Yuan smiled and said, "Don't worry, I'm here to send you a new ship. This ship is guaranteed to catch up with any enemy ship!"

Gu Jinkai's eyes lit up when he heard this, and he followed Lin Yuan to the water training ground. When he saw the boat, he couldn't help turning his mouth high, and said disappointedly: "This boat can also be used!"
