With the guidance of the top student Chen and all kinds of detailed data and parameters, everyone only needed to polish the parts needed for the steam engine. This undoubtedly saved a lot of effort.
Originally, Chen Qi wanted to hold a training class to teach everyone the principle of the steam engine and explain the manufacturing method of the steam engine.
In the end, he had promised to send out seven steam engines without paying attention, increasing the task load by more than three times.
This made him give up on the idea of training and lecturing. Instead, he led his people to start building steam engines.
He had already thought it through. With the current situation of the Eighth Route Army, there was no need to train professional researchers. It was better to directly train professional technicians and then use the assembly line to produce.
The 60 or so workers were divided into several groups, each group responsible for creating one or several specific parts, and finally, a special group was formed to assemble them.
This way, not only could it be kept confidential, but it could also increase production efficiency.
Of course, this was only a temporary arrangement. Chen Fan wasn't satisfied with the spare parts he had on hand. He planned to wait for the steam engine to come out, then he would make models of the steam engine parts, manufacture lathes, and so on. He wanted to mechanized production and increase the production of guns and ammunition.
Chen Qi warned himself over and over again that everything had to be done step by step. He couldn't get fat in one go!
He also wanted to make machine guns, rocket launchers, and high-tech weapons. However, those things could not be mass-produced at all. They were not very useful in confrontations. They were not as useful as rifle bullets.
The steam engine designed by Chen Qi was not the original steam engine, nor was it the current commonly used steam engine. It was a new type of steam engine that he had improved.
The development of the steam engine was first reflected in the improvement of power and efficiency, which mainly depended on the improvement of steam parameters.
In the early days, the steam pressure of the steam engine was only 0.11~0.13 megapascals. In the early 19th century, it reached 0.35~0.7 megapascals. In the 1920s, 6~10 megapascals were used.
In terms of efficiency, Watt's steam engine in the early days had a total efficiency of less than 3% based on the fuel's thermal value. By 1840, the best condensing steam engine had a total efficiency of 8%. In the 20th century, which was the era before Chen Qi's transmigration, the highest efficiency of the steam engine could reach more than 20%.
In terms of speed, the Watt steam engine at the end of the 19th century was only 40 - 50 revolutions per minute;
at the beginning of the 20th century, the speed reached 100 - 300 revolutions per minute, and individual steam engines reached 2500 revolutions per minute.
In terms of power, the initial single unit power was only a few horsepower, and the power of a marine steam engine in the early 20th century could reach 25000 horsepower.
The steam engine designed by Chen Qi had a total fuel efficiency of 35% and a speed of 2800 revolutions per minute. Although its horsepower was far less than that of a marine steam engine, it could still reach 1000 horsepower.
The horsepower of a steam engine used in a train was only about 6,000. The steam engine designed by Chen Qi had already reached one-sixth of the power of a train steam engine.
It was not that he could not design a more powerful steam engine, but there was no need. The stronger the steam engine, the bigger the volume, and the more dangerous it would be to use it. If he really designed it, the Eighth Route Army Munitions Factory might be able to bring down the machine.
Sometimes, being big was not necessarily good. Being suitable was the best.
A month later.
A series of explosions came from the Phoenix Mountain Munitions Factory. The rumbling sounds were like muffled thunder on a rainy day, and it really made people's ears buzz.
After a month, the first steam engine manufactured by Phoenix Mountain Munitions Factory was finally assembled. It was a big thing, at least two meters tall with a boiler. When it was started, it looked like a huge black monster with wheels on both sides.
"Did we succeed?"
The technicians beside him still could not believe their eyes. They rubbed their eyes hard and only reacted after a long time. They were so excited that tears welled up in their eyes.
"It's a success!"
"We succeeded!"
"No, I must inform the chief of this news as soon as possible so that he can be happy…"
Tang Xiaoyou looked at the steam engine in the distance that was roaring nonstop. She was also very excited. However, due to the girl's restraint, she did not shout and celebrate like the other technicians.
At this moment, she wished she could grow wings and immediately fly to the Bureau Chief to tell them the good news.
"I didn't expect this braggart to be so capable!”
Tang Xiaoyou looked at Chen Qi, who was being tossed around by a group of technicians. Her eyes lit up as she thought to herself.
The success of the steam engine test had a huge impact. That afternoon, the Bureau Chief and the others appeared at the Phoenix Mountain Munitions Factory."Good, good, really good!”
That night, the Bureau Chief held a celebratory banquet for Chen Qi and the others and gave them rewards. He also gave Chen Qi a great merit and gave all the technicians who participated a cash reward of five yuan.
After the meeting, the Bureau Chief personally received Chen Qi and praised him in many ways. Finally, he asked the key question,"Comrade Chen Qi, with the current conditions of our arsenal, how many steam engines can we produce in a month?”
Chen Qi was stunned when he heard that. Then, he thought for a moment and said,"With the current conditions of our arsenal, we can only produce five units a month at most. If we have enough steel and other materials, we can produce about ten units.”
It was not that Chen Qi wanted to slap himself in the face, but he had underestimated the difficulty of the Eighth Route Army. He had thought that it was easy to manufacture steam engines, but he had forgotten an important point, steel!
Steel, not pig iron!
Although there was a large amount of ironware in the arsenal, these ironware could not meet the requirements for making steam engines. They had to be smelted a second time, which greatly increased the difficulty of mass production of steam engines.
When the Bureau Chief heard that the Munitions Factory was in trouble, he pondered for a moment and finally slapped his thigh. He said solemnly,"The problem of steel will be solved by the headquarters. The task of your arsenal is to manufacture as many steam engines as possible. Steam engines are too important to the Eighth Route Army.”
Of course, Chen Qi knew the importance of the steam engine to the Eighth Route Army, but he had his own plan. After thinking about it, he said,"Chief, the steam engine is indeed important. However, the disadvantage of the steam engine is that it is large and loud. It is easy for the enemy to discover it.
Therefore, my suggestion is to only manufacture a few units for now and send them to the coal yard, ironworks, and oil mines. The rest will be used to start the furnace and make steel. As long as we solve the steel problem, we can refine oil and make internal combustion engines.”
"The internal combustion engine is small in size, low in noise, and has many uses. If it is sent to other military factories, it will not easily attract the attention of the Japanese.”
"Moreover, with the engine, we can also make cars, motorcycles, planes, and tanks in the future!”
Chen Qi's concern was not that he was overthinking things. Yanzhou was the Eighth Route Army's headquarters, and there were still Japanese spies. There were even more spies in the other enemy areas.
The steam engine was too loud, and it was easy to expose the location of the arsenal. It was better to wait until the diesel and gasoline engines were manufactured before sending them over.
After the Bureau Chief heard this, he thought about it seriously and finally agreed to Chen Qi's suggestion. However, he still asked Chen Qi to make a few more steam engines and send them to some secret military factories for use.
Chen Qi had no objections to this. At the same time, he told the Bureau Chief what he would do next.
Now that the steam engine had been built, the next step was to start the furnace and make steel!
Of course, before that, Chen Qi still had one more thing to do. He needed to make some small toys to make the black monsters in the square quiet down.
