Daming Town Haiwang

Chapter 1082, the steamship problem

"If the train doesn't follow the tracks, it seems that accidents are easy to happen!"

Liu Jin looked at the expressions of the two and smiled inwardly.

Because of the existence of himself as a traverser, Daming's technological development can be regarded as a cheat.

Taking the steam engine as an example, if he didn't take the lead and allocate special funds for people to study this thing, to be honest, this steam engine may not be researched until the year of the monkey.

Although the principle of the steam engine is very simple, and there is no high technical content, this thing sometimes needs someone to click it before it can be produced. Under normal development conditions, I am afraid that it is very difficult in the soil of Daming. Difficult to conceive.

Even though the rapid development of capitalism and colonialism has promoted the improvement of productivity, it may take a long time to come up with this steam engine.

There are also new looms and spinning machines, the reason is the same.

There is no doubt about the importance of these two things. Without these two things, Daming's textile industry would not have been able to develop rapidly.

The textile industry is now the fastest growing industry in Ming Dynasty, and it is also the industry with the most capitalism. More and more large factories and workshops have begun to have the prototype of the factories of later generations.

Normally, the invention of these two things requires an accidental discovery.

But with Liu Jin, the traveler, it is different. Not only was it invented in advance, but it was also quickly popularized under Liu Jin's promotion, which promoted the development of the textile industry in Ming Dynasty.

The same is true for the development of steam locomotives and steamships. They are all led by Liu Jin, and they are also key things. In many cases, Liu Jin does not need to study these things by himself.

You only need to give some hints on the key points, this is what the traverser should do.

Daming people are no worse than any nation in the world, even smarter and wiser than most other nations. There are so many skilled craftsmen. As long as these skilled craftsmen are given a platform to display their abilities, it will naturally promote the development of Daming technology. rapid development.

The biggest problem facing the Ming Dynasty is not the lack of smart people, nor the lack of people who are good at thinking and discovering, but the social system of the Ming Dynasty. Under the system of stereotyped selection of scholars, the thoughts of the entire society are firmly controlled , Reject new ideas and new things, this is what hinders the development of Ming Dynasty.

Confucianism has developed to the present, and has gone astray. The long-term monopoly rule of this land has stopped the development of Confucianism, and gradually stagnated, and extremely rejected other theories, hindering the development and progress of the entire society.

This is also the reason why Liu Jin opened a new school, because new things must be injected, and new ideas and theories must arise to bring new vitality and development to this ancient land.

"By the way, tell me about the research on steamships."

Steam locomotives should be available soon. With high-power steam engines and rail tracks, trains can be produced soon.

Of course, relying on the train alone is not enough. The vast territory of the Ming Dynasty, even the Pacific Ocean is an inland sea, and it is definitely not possible without fast sea navigation tools.

So Liu Jin also asked about the research on steamships, to see what difficulties they encountered, and whether he could give some pointers based on the experience of later generations.

Hearing Liu Jin's words, Ren Siheng said helplessly, "Grand Liu, you should come with me and have a look."

After speaking, he also took the lead to walk to the location of the steamship research project, and said while walking: "The steamship research, we mainly cooperate with Tianjin Shipyard, and the main location of the project is also placed in Tianjin. "

"However, the most important thing about this steamship is not the steamship but the steam power. On the capital side, we are also studying how to apply steam power to the ship."

"Our ships have always been powered by sails. In terms of relying on steam power, our first thought is to use oars, use steam engines to drive the oars, and then use the oars to drive the boat."

"..."

Ren Siheng explained their research ideas and directions to Liu Jin in detail.

Naturally, there is a huge difference between a steam ship and a traditional sailing ship. People from the Mechanical Research Institute, Tianjin Shipyard, and the Academy of Naval Architecture have also jointly studied it for a long time.

Soon, under the leadership of Ren Siheng, Liu Jin and Zhu Houzhao also came to the steamship research project team.

"Liu Gong, this is the paddle we researched~"

In the huge laboratory, Ren Siheng pointed to a long row of paddles and said.

This paddle has many paddles and is connected by a long screw. When it is connected to a steam engine, the paddles can be pushed to work by steam power.

"In the beginning we used wooden oars, but wooden oars are very fragile, especially when the steam power is strong enough, it is easy to break."

"We switched to using metal to make oars. Metal oars are more durable than wooden oars, but because of the steam engine, when we were on the boat, there was a terrible vibration, which caused the boat to be damaged and unusable. Too long and the whole ship is destroyed by the shock."

"In addition, the wear of this bearing is very severe, and it will be damaged after not being used for too long. The most important problem is that such a set of devices is installed on the ship. The speed of the ship is very slow, and it is not even as fast as the wind. sailboat."

When he said this, Ren Siheng couldn't help shaking his head.

To be honest, the research on steamships is the biggest problem he has encountered now. There are so many various problems that many people involved in the research think that there is no way to use steam engines on ships.

The vibration generated by the operation of the steam engine is enough to shatter the ship. The wooden ship can hardly withstand the work of the steam engine, especially after the horsepower of the steam engine comes up, the structure of the wooden ship cannot bear the strong vibration. .

The second is the problem of wear and tear. The oars are not durable, the bearings are easy to break and wear, and there are many reasons such as low efficiency and too slow speed, which make everyone think that steam power is not suitable for use on ships.

The progress of research has been very slow, and there is still no way to research a satisfactory steamship.

Liu Jin listened carefully, and then looked at the oars in front of him. To be honest, he was a little dumbfounded.

"Is this a paddle?"

"Shouldn't it be a propeller?"

"How many oars do you need?"

"The limitation of this thinking is too big. I even thought of using a dragon boat race to push the boat with paddles on both sides. With such a long wheelbase, even the best bearings can't stand it. The motivation will be wasted."

Liu Jin also couldn't help shaking his head.

The ships of the later generations are all propelled by propellers, and the propellers are not big. Even if the propellers are as huge as an aircraft carrier, they are very small compared to the huge body of the aircraft carrier.

Looking at the oars in front of him again, Liu Jin wanted to laugh immediately.

However, Liu Jin still held back.

Ren Siheng and the others are walking a path that no one has ever taken before. After feeling the stones and referring to the existing experience, it is understandable to make such a paddle.

Development requires a process, and at the beginning, many things seem ridiculous.

Just like airplanes, the initial airplanes look very simple and ridiculous, but as long as you keep exploring, you can create more and more powerful airplanes.

The same is true for the development of ships. The first ship may be a plank, or even a tree, and then gradually develop into a canoe, and finally develop into a large aircraft carrier of later generations.

Although the oars in front of us are far from the propellers of later generations, they were also researched by people like Ren Siheng and others.

Well, don't laugh, definitely don't laugh.

Liu Jin said to himself silently in his heart.

"Ren Siheng, in fact, you don't need to get so many oars, and you don't need to get such long bearings."

"We can change our thinking and make a propulsion device directly behind the ship's butt, and then this long screw can also be turned into a short screw."

"Well, maybe this screw can be directly made into a blade shape, making it look like a spiral. Try it this way, maybe it will have different effects."

"Experiment more, use more new methods, try some new things, and don't be limited and bound by thinking."

"Why does this power have to be used on both sides of the ship?"

"The back of the boat is fine too."

After thinking about it, Liu Jin also said to Ren Siheng, explaining the concept of propellers in later generations.

If Ren Siheng is allowed to continue to study this kind of oars, who knows when he can develop a steamboat that can be put into use, using steam power on traditional oars.

It's really a waste of steam power, and the long connecting bearings are very easy to damage, and the oars are also easy to break.

"Short screw?"

"The screw is made into a blade shape?"

"Make it look like a spiral."

"Put it in the back of the boat?"

When Ren Siheng heard it, he couldn't help but widen his eyes slightly, feeling that Liu Jin's thoughts were a bit unconstrained, but he still hurriedly remembered Liu Jin's words firmly.

Although Liu Jin is not engaged in these researches, but Liu Jin is a child of a master, and some of the things he often guides make their research progress by leaps and bounds.

This is not only the case with their Mechanical Research Institute, but also the Iron and Steel Research Institute, the School of Construction, the School of Chemical Engineering, etc. Many things can quickly make great progress through Liu Jin's guidance.

"The words of the disciples of the master must contain profound truths!"

Ren Siheng remembered it firmly, while Zhu Houzhao who was beside him frowned.

"Is that okay?"

　Something is delayed, the update is late~
