Open an aircraft carrier to fight against Japan

Lin Yuan quickly said: "I was too anxious and didn't make it clear. I mean, use the engine of the plane to generate electricity. The engine of the plane is a gas turbine!"

Qiu Xian echoed: "That's right, in our era, the gas turbines used in many thermal power plants are modified from aircraft engines."

Lin Yuan said: "Yes, on the plane, the high-temperature gas drives the turbine to rotate and then jets out of the plane to propel the plane forward. If the plane's engine is converted into a generator, then a free engine is installed after the turbine. The turbine, let the gas drive the free turbine to rotate, and the free turbine drives the generator to rotate, and then electricity can be generated.”

Qiu Xian said: "This kind of modification technology is not in the scope of our research, let's design the generator."

Lin Yuan said: "Don't worry, I will find relevant experts for engine modification."

Lin Yuan then contacted the Beijing ship, and the ship's aero-engine expert, Liao Ming, soon came to the industrial area.

The engine used by the J-25 carrier-based aircraft on the Beijing ship is the latest turbofan-30 engine developed by my country. The aero engine has always been known as the jewel in the crown of industry. It is a concentrated expression of a country's comprehensive national strength and industrial strength. An excellent aero-engine is not so much designed as it is modified. Therefore, the Ministry of Industry and Information Technology (formerly the National Defense Science, Technology and Industry Commission) specially assigned aero-engine experts to follow the ship, and any problems with this type of engine will be resolved at any time. Make a note.

Academician Liao Ming can be regarded as a wonderful flower in the field of aero-engines. Aero-engines are a kind of fluid machinery. Its development work is divided into two main lines: one is the gas line, which studies the parts related to gas inside the aero-engine. For example, the gas flow field design of the compressor, the temperature field design of the combustion chamber, etc.; the other is the force line, which studies the structure, strength, etc. of the aero-engine.

It is good to be proficient in one of these two lines, but Academician Liao Ming is proficient in both, so the relevant leaders assigned him to board the ship. Like many aero engine experts, academician Liao Ming's biggest characteristic is that he has no characteristics. He is the kind of old man who can't be found in the crowd.

After hearing Lin Yuan's request, Academician Liao Ming didn't hesitate at all, and said with a smile: "We have done this kind of thing many times. The three major components, the high-pressure compressor, the combustion chamber, and the high-pressure turbine, are collectively called an aero-engine. The core engine of the turbofan-30 has superior performance and has a very powerful modification capability, it can be called a transformer among aero-engines! It can not only be converted into a generator."

Lin Yuan asked, "What else can it be transformed into?"

Liao Ming said: "It can also be converted into an engine used by warships. In our era, the performance of the turbofan-30 modified naval engine completely surpassed the American LM2500. After installing this engine on our destroyers, the maneuverability It directly surpasses the king of destroyers - the American Arleigh Burke-class destroyer, if you want to build a warship in the future, we can also use it to modify it, and the maneuverability is guaranteed to surpass the warships of this era!"

Lin Yuan said: "We have to hurry up and build warships. The current warships really can't meet the requirements."

Liao Ming asked: "Although I am not an expert in related fields, I also know that building a warship requires a lot of equipment. It may not be easy to get all these equipments in place."

Lin Yuan said: "It's okay, I've made up my mind. The matter here is almost done. I'll go to the Jiangnan Manufacturing Bureau and get their shipyard."

At this point, the two looked at each other and smiled. It turned out that they had strayed from the topic before they knew it. Lin Yuan asked: "How much power can be achieved by converting a turbofan-30 into a generator?"

Liao Ming said: "According to our improvement experience, the power can reach 4 megawatts."

Lin Yuan asked: "I know that the service time of an aero-engine is on the order of ten to the third power. This time is obviously not enough. Is there any way to greatly extend this time?"

Liao Ming said: "In the process of power generation on the ground, the gas does not need to have a high temperature, so we can lower the temperature. According to our experience, reducing the temperature by [-] Kelvin can extend the use time to the fifth power of ten. Magnitude."

Lin Yuan said: "We took out two engines, which are almost enough. Is there any difficulty in the modification process?"

Liao Ming said: "Basically there is no difficulty. When refitting, we need to remove the fan and the external duct, so that we need to redesign the low-pressure compressor casing, intermediate casing and other components, but you can rest assured that due to the improved The aero engine does not need to go to the sky, so we don’t need to consider the weight, we can use carbon steel, or even cast iron; there is also the design of the power turbine, we can’t make a power turbine now, but we can use another engine’s turbine replace."

Lin Yuan said: "We will definitely use gasoline or diesel as fuel in the future, so do we have to redesign the combustion chamber and nozzle?"

Liao Ming replied: "That's right, don't worry, we all have relevant experience, and the materials and equipment are completely sufficient!"

Lin Yuan thought: "In this way, the problem of power generation has been basically solved, but another problem has become prominent, and that is the problem of oil!"

The improved generator can use aviation fuel in a short period of time, but gasoline or diesel oil will be used in the future. Both gasoline and diesel oil are products of the petroleum industry. After heating and fractionating, diesel oil or gasoline can be obtained.

Thinking of oil, Lin Yuan felt excited. If we look at the history of human development from the perspective of energy, coal undoubtedly triggered the first industrial revolution, and the large-scale exploitation and utilization of oil triggered the second industrial revolution. Gasoline and diesel, which are distilled in the middle, give the internal combustion engine unprecedented power; lubricating oil makes various parts run efficiently.

Petroleum is also an important source of organic chemical raw materials. Rubber made from petroleum raw materials has made it possible for cars to move forward; synthetic fibers and plastics have fundamentally changed the basic necessities of human beings...Lin Yuan returned to the governor after finishing arranging the industrial area. At the Yamen, when he was conceiving the oil industry, a master ran in in a panic and said, "My lord, something is wrong. There is a group of British missionaries in the village near Fengtian."

Lin Yuan asked: "They are here, what are you doing in such a panic?"

The master said: "Don't you remember the lesson plan?"

Lin Yuan said: "The Chinese people are not murderous monsters without blinking an eye. What happened to the British in the countryside? Do the Chinese have to kill them!"

The master said cautiously: "These foreign devils are all masters at touching porcelain. If there is something wrong, it would be bad for them to be ripped off."

After hearing this, Lin Yuan thought, "This group of people are scared by the foreign devils!" So Lin Yuan smiled nonchalantly, "Why panic! Isn't it the foreign devils! Do they dare to come and take advantage of the governor?"

The master quickly laughed and said, "What your lord said is that you defeated the Japanese and Russians..."

Lin Yuan knew that what he said next was flattery, and he didn't want to hear it, so he waved his hand and said, "Let's go, let's meet those missionaries together."

When he got to the place, Lin Yuan almost laughed out loud.
