Carrying AK into Ming Dynasty

Chapter 759 Human Tractor

After three years of vigorous development, the Ordnance Institute has now grown into a mature military industrial group with more than 1 craftsmen and workers of various types.

After the practice of previous wars, the imperial court also paid more and more attention to the ordnance factory. Not only did it specially dispatch [-] soldiers to defend it, but the five miles around each firearms workshop were also designated as military restricted areas. The entrants were directly detained without asking the reason.

Liu Hongjian and Chang Yu went directly to the headquarters of the Ordnance Institute on the mountainside of Xishan Mountain. Those who can stay here are the backbone of the Ordnance Institute. Unlike the workshops at the foot of Xishan Mountain that have already formed a mature assembly line, the craftsmen here specialize in developing and testing new products. firearm.

"Mr. Song, I haven't seen you in a few months. Don't come here!" As soon as Liu Hongjian entered the research room, he saw Song Yingxing bending over something covered in oil, and there were several craftsmen's assistants standing around him.

"Hehe, Mr. Song has met your lord!" Song Yingxing looked back and saw Liu Hongjian clasped his hands, and the other craftsmen also rushed to salute.

"What about Mr. Song? The steam engine has been improved successfully?" Liu Hongjian saw a steam engine in the room and another big one he hadn't seen before. He glanced at it and asked.

"Yesterday, I heard that my lord returned to Beijing. Originally, I planned to visit him personally, but I was worried that my lord would have to travel a long way, so I didn't bother him. I just wanted to report the progress of this new steam engine to my lord."

Song Yingxing washed his hands in the washbasin, and pointed to the big steel man in the corner as he walked.

"Please look, my lord, this is the steam engine that our Beiyang Navy is currently using. Since last year, the old man has been racking his brains with the late emperor, intending to improve the efficiency of the steam engine.

But the boiler of the steam engine has to withstand heavy pressure, so it must be made of thick steel. A set of steam engines weighs more than 400 kilograms. Even if the first emperor came up with the method of multi-stage linkage to increase the power, it is still too bulky for thrust. There are big changes.

Moreover, the operation of our existing steam engines is complicated, and at least [-] people must be assigned to take care of each node on a main battleship. The most serious thing is that the boiler is easy to explode after being used for a long time. "Song Yingxing pointed to the steam engine in the research room.

If Liu Hongjian didn't understand these technical things at all before, but after returning from a trip to Nanyang, Liu Hongjian almost learned it without a teacher.

Of course, Liu Hongjian knew the various shortcomings and deficiencies of the steam engine. Qi Yuangong would report to him almost every day that the steam unit of the No. ship was broken, where the boiler exploded, and so on.

In fact, the most deadly thing is not what Song Yingxing said. The most fatal thing about a steam engine in a war is its starting speed. If a warship wants to start, it must boil the boiler, and once it boils, it cannot be stopped at will.

If the Beiyang Navy encounters a surprise attack when the steam engine is not started, it will almost always become a competent target.

"Then what? Was this thing developed by Song Laoxin?" Knowing that Song Yingxing said so, Liu Hongjian must have thought of a solution, pointing to the new machine on the ground.

"Yes, my lord, this is the result of three months of research and development by the old man and your colleagues, and it is still a semi-finished product, Xiao Sun, let you explain the principle of this to the prince!" Song Yingxing seemed to be thirsty while pouring water , while pointing at the young Sun Yun fairway.

"Yes, Master Song, Master Shan, please take a look." Although Sun Yunqiu was young, he was not panicked.

"Wait a minute? Are you a student of the Engineering College?" Liu Hongjian asked casually when the young man called him the head of the mountain.

"Yes, my lord, this boy is the first batch of students of our engineering college, and he is also one of the few people with the highest understanding. Speaking of which, the idea of ​​this new steam engine was proposed by Xiao Sun!" Song Yingxing handed the tea to him. Liu Hongjian was even more generous in his praise.

Sun Yunqiu didn't take the credit, but humbly said that it was all thanks to the masters, which made several old craftsmen around nod frequently.

"Master Shanchang, as we all know, the boiler and cylinder of our steam engine are separated, the boiler is burned outside, and the steam heat generated by the combustion is transferred to the cylinder, and then drives the turbine.

It was only when the disciple entered the Ordnance Institute that he discovered that the heat loss of this kind of external combustion is too high. Even if the masters have been working on heat conduction, it is still difficult to greatly improve the efficiency of the steam engine.

The disciple then wondered if it was possible to change the external combustion to internal combustion, that is, not use steam as the working medium, combine the boiler and the cylinder, and use the flue gas after combustion to directly drive the turbine to operate. "Sun Yunqiu explained while pointing around the machine.

"Hehe, Xiao Sun, turn on the machine and show me!" Song Yingxing urged, knowing that Liu Hongjian didn't like to hear such complicated things.

"Hey, disciple, let's start now, Master Shanda, stand back." After Sun Yunqiu finished speaking, another craftsman walked out of the crowd to help.

The craftsman was responsible for pulling the bellows to blow air into the machine, while Sun Yunqiu took out a red-hot iron rod from the charcoal fire nearby and inserted it into the machine. After confirming with the bellows puller that it was ready, Sun Yunqiu opened the valve.

chug - chug - chug - chug - chug -

There was a sudden loud roar from the machine, black smoke was coming out of the exhaust port on the top of the machine, and at the same time the turbine at the other end of the machine began to spin at a very high speed.

Liu Hongjian's eyes were straightened.

Because the sound is a bit familiar, isn't this a tractor?Or a veritable 'human' tractor!

Another reason why Liu Hongjian was surprised was that he only handed over the blueprint of the steam engine to Song Yingxing, but did not hand over the blueprint of the internal combustion engine.

The reason is very simple. It took nearly 100 years for the Europeans to go from the steam engine to the internal combustion engine. Liu Hongjian thought he still wanted to make good use of the steam engine until the technology matured in the future.

I never thought that Da Ming would be able to teach himself without a teacher, what a genius!

Only then did Liu Hongjian understand why Sun Yunqiu asked him to back off. The machine only roared for less than a quarter of an hour and then turned off. In just this moment, the two closest to the machine, Sun Yunqiu, were smoked into black charcoal.

"My lord, this new steam engine is still in the experimental stage and cannot be used for a long time. If the fuel problem and ignition problem are solved, most of the shortcomings of the old steam engine can be avoided." Song Yingxing sighed.

But the fuel problem is not so easy to solve, and every advancement in technology almost takes all his energy.

"What's in this jar?" Liu Hongjian asked, ignoring Song Yingxing's concerns, pointing to the iron jar on the ground.

"My lord, this is gas, which is provided by the steel workshop in Zhending Mansion." Song Yingxing said.

It is not uncommon for the craftsmen of Zhendingfu Iron and Steel Workshop to find this thing as a companion to gas and coal coking. It is really convenient and quick to burn, but its disadvantages are also obvious, and it is not resistant to burning.

At this time, there is no pressure tank, and the collected gas is just gas, which is not only not durable, but also easily leaks after a long time.

"I have a way to solve the fuel problem." Liu Hongjian said with a happy face.

"Oh? Sir, what can you do?" Song Yingxing asked hastily.

"Oil! Oh, that's kerosene."
