Wuhan, Sugon Power Company.
Next to the beautiful Han River and adjacent to the Sichuan-Hankou Railway, there is a new factory that was only established during World War I.
This is Sugon Power.
Its predecessor was a branch factory of Hanjiang Steam Turbine Company of Tuojiang Power Equipment Group, and it was a third-level subordinate organization of Tuojiang Power Equipment Group.
Its main project is a new type of power system.
Originally, because the technology was not mature, there were no mass-produced products.
It was not until 1914, after a technological breakthrough, that real products began to be produced.
The government and the upper management of the group attach great importance to this new power system, so it was upgraded from a branch factory to a company.
At this time, in Sugon Power's test workshop, a piece of power equipment with a different shape than the traditional one was lying on the test bench.
Its main shape resembled an elephant drum enlarged hundreds of times, and its length was more than 15 meters. , nearly 5 meters in diameter.
"Yes, Premier Zhang, this is a brand-new power machine called gas turbine," Feng Ru, chief engineer of Shuguang Company, excitedly introduced to the Prime Minister who came to inspect.
"Based on the previous gas turbine for power generation, after more than five years of research and development, we finally achieved the miniaturization and high power of the gas turbine.
This is how we have the current rc0320 ship gas turbine."
This Feng Ru is the one who built the airplane in the original time and space, but his fate has changed in this plane.
After he was "abducted" by Xingke, he did not build airplanes.
Well, in fact, Xingke didn't like his airplanes at all.
He took another path, because Xingke discovered that this man actually had a lot of knowledge about steam turbines, to be precise, gas turbines, so he first arranged for him to go to Southwest University of Technology for further study, to learn relevant information and supplements for later generations.
After a year and a half of advanced study in basic knowledge, he was assigned to the Tuodong Group to study gas turbines.
Facts have proved that this change was correct.
Feng Ru, who switched his career to gas turbines, quickly achieved results.
In 1914, he developed the first gas turbine that could be used to generate electricity, with a power of 5,000 kilowatts and a thermal efficiency of 30.
In March 1919, Sugon manufactured the first gas turbine for ships, which was installed on a Wuchang-class frigate for experiments.
The test was very successful, and the frigate ran at a high speed of 38 knots.
In the following years, they continued to improve and improve on this basis.
With the rapid development of high-temperature resistant material technology and processing technology, their gas turbines are getting better and better, with greater power and longer life.
The current rc0320 marine gas turbine is their latest product, with a power of 20 megawatts and approximately 26,800 horsepower.
It is a gas turbine specially developed for large ships.
Zhang Lizheng just observed the complete test run of this gas turbine.
After 24 hours of full load operation, the situation is still very stable, which shows that this gas turbine is fully ready for shipboard use.
He nodded and said with joy: "Well, very good, Mr.
Feng.
Your Dawn has made significant contributions to our country's power industry.
Gas turbines are the best warship power.
The starting speed and power to volume ratio of steam turbines are too high."
The low speed, especially the starting speed, is a flaw of the steam turbine and cannot be improved no matter how hard it is.”
A total of eight units of this batch of rc0350 gas turbines have been produced, six of which will be used for the transformation of the Andrea Doria and the United Empire, and the other two will be used as backup.
In fact, if it were not for waiting for this gas turbine, the two ships would have been renovated long ago.
Yes, the power systems of these two ships will be replaced with gas turbines, which are more advanced than steam turbines.
Zhang Lizheng said to Feng Ru: "Mr.
Feng, gas turbines are not only used for power generation and ships, they can also play an important role in the aviation field.
Your next task is to continue to improve and improve high-power gas turbines." , which is to further miniaturize and lighten it so that it can be used on aircraft."
"Yes, Premier Zhang.
We will speed up the research and development of gas turbines in the aviation field and strive to build our jet aircraft as soon as possible."
When he mentioned the aircraft, Feng Ru's eyes lit up.
Even though he has changed careers now, his love for aviation has not diminished at all.

The basic theory of jet aircraft existed more than ten years ago, earlier than the first aircraft appeared, but there was no suitable power equipment.
Although something like a gas turbine is very high-end, its history is actually quite long.
Its theory appeared as early as the 18th century.
At the end of the 19th century, German engineer Stolzer built a gas turbine, but it failed because it could not operate independently from the starter.
By 1905, Frenchmen Le Maire and Amango made the first gas turbine that could operate independently, but the efficiency was too low and it was not practical.
In other words, it actually came out at about the same time as its cousin the steam turbine.
It is just limited by materials, processing technology and design defects, and its development speed is far slower than that of the steam turbine.
If we follow the historical evolution of the original time and space, it was not until 1920 that the first practical gas turbine was made by German engineer Holzwart.
This unit has an efficiency of 13 and a power of 370 kilowatts.
It works according to a constant volume heating cycle.
However, because the constant volume heating cycle heats in an intermittent deflagration manner, it has many major shortcomings and was abandoned.
It was not until 1939 that the Swiss built a four-megawatt gas turbine for power generation with an efficiency of 18.
This was the beginning of the practical use of gas turbines.
By this time, steam turbines were everywhere in the world.
With Mr.
Wen's intervention, things are naturally different.
The theory and design of gas turbines are directly copied from later generations, and there is no need to make any detours at all.
With the support of later generations of data, there is no technical bottleneck.
In fact, if it were not limited by materials and processing technology, this thing would have come out a long time ago.
Of course, it is not impossible to manufacture gas turbines in small batches if you use the things in the office building base, but it is not cost-effective.
After 1918, China did not continue to sell dumplings and build large warships like other great powers.
The ostensible reasons were the construction of merchant ships for the Allied Powers, which consumed a large amount of shipbuilding capacity, and the impact of the Spanish Flu epidemic.
But these are only some of the reasons.
Waiting for this new power system is also a very important reason, at least one of it.
Anyway, those steam turbine warships are already sufficient, there is no need to continue to waste resources.
If new ships are to be built in the future, it will naturally be powered by gas turbines.
Although the power system of warships can also be modified and upgraded, it is also a waste of manpower and material resources.
You must know that any major modification of this kind will require the warship to be disemboweled, occupying valuable docks and a lot of man-hours.
Of course, steam turbines also have a very important mission.
As Prime Minister Zhang Lizheng said, this thing is the front-end technology of turbojet engines.
If you want to light up jet technology, you must first light up the technology tree of gas turbines.
As for the big map of the original space and time that lit up this technology tree upside down, that was completely a special case, and it was only done like this in the whole world.
It's not impossible to play this way, but it leaves a lot of sequelae, such as unstable foundations and other problems.
Therefore, the equipment of Datu Dynasty has had "heart disease" for a long time, and it took a long time to make up for it.
The development of science and technology has its own rules.
The order in which the technology tree is lit is very important.
It is not impossible to play it upside down, but the cost is extremely high.
It was like the United States in the original time and space lit up the technology tree of the atomic bomb upside down.
The normal process should be to build the nuclear power plant first and then the atomic bomb.
But at that time, in order to catch up with the schedule, they just built the atomic bomb first.
The cost was heartbreaking.
Compared with the mainstream power steam turbines used in current warships, gas turbines have generational advantages.
The first overwhelming advantage is the start-up speed.
Don’t even think about it taking less than an hour to start a steam turbine, while a gas turbine only takes a few minutes.
This is an extremely important performance in the military field.

Just like the Pearl Harbor incident in World War II in the original time and space, if the U.S. warships at that time were equipped with gas turbines, they would be able to start quickly when they discovered that Japanese planes were attacking, and they would be able to carry out either counterattack or evasion, and they would not stop stupidly.
If you are bombed on the spot, the loss can be reduced by at least half.
The second overwhelming advantage is volume.
Although gas turbines have no obvious advantage in thermal efficiency, their power to volume ratio is eight blocks ahead of steam turbines.
Because there are less boilers and pipes, the gas turbine only needs one-fifth or less of the volume of the steam turbine at the same power output.
The space on a warship is very precious, and the power system uses a lot of space.
By switching to a gas turbine warship, the space saved can be used for other purposes.
It can be used to add weapons and equipment to enhance combat effectiveness.
It can also increase the living space and improve comfort.
It can also store materials and increase the duration of combat.
For example, the Andrea Doria and the United Empire are currently being renovated.
These two warships were built in the style of the Iron Turtle from the beginning.
The space for the power system is extremely limited.
If steam turbines continue to be used, even China's steam turbines The units are more advanced than those in Austria and Italy, but their power is unlikely to increase much.
But if you switch to a gas turbine, it will be completely different.
Doubling or tripling the power is not a problem at all, and it can also free up a lot of space.
Of course, gas turbines also have their disadvantages, which is the high cost of use.
Because its fuel consumption curve is almost straight, no matter the output power is high or low, there is almost no change in fuel consumption.
In other words, at low speeds, this is a gas guzzler.
And it is also picky about fuel.
Unlike steam turbines, which can use the cheapest heavy oil, gas turbines must at least use heavy diesel with fewer impurities.
In addition, the life of the unit is shorter than that of the steam turbine.
But this is not a problem for Mr.
Wen.
China, which has popularized diesel trees, does not lack fuel.
Moreover, we can also use "alternating combustion and combustion" as in later generations, using high-power gas turbines for high speeds, low-power gas turbines for low speeds, "combined combustion and combustion" with diesel engines for low speeds, or even more advanced "combined gas and electricity".
As for the problem of "short unit life", there is no solution.
After all, the working environment and principles are completely different.
With the same materials, gas turbines cannot exceed steam turbines in terms of service life.
But compared with the benefits it brings, this small flaw is tolerable.
It's like the hovering performance and low-altitude and low-speed performance of a monoplane are completely impossible to compare with that of a biplane, but in the end the sky still belongs to the monoplane. presidential palace.
A far-reaching meeting is being held today in the conference room of the Presidential Palace.
There were not many people attending the meeting, only 9 people in total.
In addition to Wen Desi and Gu Xiaolan, they were Liu Yang, Chairman of the Federation of Finance and Finance, Ban Chuanzhi, Vice Prime Minister and Minister of Industry, Wang Qi, Minister of National Security, Xue Dingmao, Director of the Battery Research Institute, and several others.
A senior expert.
The faces of most of the attendees were beaming with joy.
Xue Dingmao, director of the Battery Research Institute, first reported on the overall progress of the project: "Mr.
Wen, we have made breakthrough progress in the first phase of our work, and practical samples have been made.
The performance is unexpectedly good.
This is a report on the specific situation. " Xue Dingmao sent a piece of information to everyone present with a blushing face.
On the conference table in the middle are several silver-gray, lunch box-sized metal rectangles with two silver-white protrusions on one end face.
There was not much content in the information.
Wen Desi read it quickly and asked with bright eyes: "Is this true?
Can the cost really reach below 5 yuan per kilogram as stated in the report?"
"Yes, Mr.
Free novels bring you joy and joy ---> storyskyline.net
Wen, we asked experts from Finance and Finance to demonstrate the production cost.
This price is based on the currently designed reliable process and estimates of site, equipment, raw materials, energy consumption and personnel costs.
If a large number of Production, the price can still be reduced."
Director Xue looked at Liu Yang and replied firmly.
Liu Yang also smiled and nodded: "We have calculated this cost price conservatively.
If we continue to improve the process, the cost can be reduced."
"Well, the price is acceptable.
So what are the prospects for expanding production?"
Wen Desi turned to Ban Chuanzhi next to him and asked with concern.
"If we fully produce according to the current scale of Nanyang No. 1 Factory, we can reach a monthly production level of 1,000 tons.
Experts from our Ministry of Industry system have jointly evaluated this.
According to the current raw material preprocessing speed, we can achieve a monthly production of 3,000 tons at most. tons level.
We plan to expand two more factories so that we can reach a monthly production level of 10,000 tons.”
This high-energy iron battery was actually ready for mass production in the second half of 1919, and a "new battery factory" was established in Nanyang for trial production.
However, the defective rate is unsatisfactory, and more importantly, the price has always been quite impressive, so there is no mass production.
Of course, this dissatisfaction is only in comparative terms, and is aimed at the Wen Desi from later generations.
To people of this era, it is already a tyrannical, cool and explosive thing.
Therefore, there is an urgent need to improve the process.
Until now, the defective rate and cost have finally reached an acceptable level, and the performance has also been improved.
Only then are we ready to carry out large-scale mass production and put it into practical use.
Not to mention by today's standards, even by the standards of the early 21st century, the performance of this battery is amazing.
Qualified products of this high-energy battery are divided into three grades.
The most advanced first-class product has an energy density of 1,200 Wh kg, a power density of 3 kW kg, a charge and discharge cycle of 700 times, and a production ratio of 20.
The intermediate second-class product has an energy density of 900 Wh kg, a power density of 2.1 kW kg, a charge and discharge cycle of 500 times, and a production ratio of 45.
The low-level third-class product has an energy density of 600 Wh kg, a power density of 1.6 kW kg, a charge and discharge cycle of 400 times, and a production ratio of 35.
Even the lowest third-class product, regardless of energy density and power density, can guarantee to provide large current when starting a high-power motor.
It can work normally in the range of minus 30 degrees Celsius to 60 degrees Celsius.
The self-discharge rate after being placed at 45 degrees Celsius for 10 days is less than 5.
At 60 degrees Celsius, the charging efficiency is as high as over 95.
"Vice Premier Ben, the arrangements for the expansion of production must be stepped up.
The consumption of this kind of battery will be very huge, and the production cost must be further reduced.
Chairman Liu, you are responsible for allocating funds, and the budget must be given the green light.
Director Xue, you To continue research, there is still great potential for improvement of this battery , the energy density should continue to increase.
Minister Wang, the emergence of this kind of battery will have a huge impact on the entire society, especially its military role, which can be described as expensive, so you must dispatch capable personnel and keep it strictly confidential.
"Wen Desi began to assign tasks to the participants.
"Mr.
Wen, please give this battery a name," Xue Dingmao said with a smile.
"Oh, okay.
Let me think about it."
Wen Desi smiled and nodded.
After thinking for a while, he said: "Since the material of this battery is mainly iron, and the symbol of our country is the dragon, then it is called iron.
Dragon battery, how about” "The Dragon of Steel, let's call it the Iron Dragon Battery."
Everyone immediately praised it.
That's right, it's not a Jinlong battery, haha.
Well, in President Wen's time, there was indeed a high-energy battery called "Golden Dragon Battery", but the performance of that product was much better than the current one.
Free novels bring you joy and joy ---> storyskyline.net
The difference was as far away as the price of gold and black iron.
If this kind of battery is called the Golden Dragon battery now, then what should we call the more powerful thing that comes out in the future?
It would be better to be more low-key and call it the Iron Dragon battery.
Its main material is originally iron.
When better things come out in the future, you can upgrade the bronze dragon, silver dragon, gold dragon, crystal dragon, and gem dragon all the way up.
In Mr.
Wen’s view, the practical implementation and formal production of high-energy batteries is of extremely great significance.
This is a major revolution in the energy field.
Its significance is not even under controllable nuclear fusion and normal temperature superconductivity, so it is named with the word "dragon", which has different meanings to China. s: This battery is indeed not as good as the Golden Dragon battery in Xingshi, so it was downgraded to an Iron Dragon battery, oo:
