After five years of teaching support, Daming became an empire on which the sun never sets.

Chapter 301 I Made a Steam Turbine in Elementary School
"The function of the steam engine is to convert the huge internal energy of steam into mechanical energy, and then apply it to various production fields."

"The steam engine can directly trigger the first industrial revolution, so the invention and use of the steam engine is of epoch-making significance. The steam engine has completely changed society and brought human society from backwardness to civilization."

"Now, please give full play to your imagination and think about the ways in which the steam engine can be used." Qin Yu said, "As a student, you must be diligent in thinking. Thinking will make you smarter."

Qin Yu's teaching method has always been inspiring teaching, allowing students to diverge their thinking.

"The steam engine can be used on the textile loom!" Zhu Xi said.I thought excitedly in my heart: The textile industry in my Ming Dynasty is very developed in various places in the south of the Yangtze River, and weaving is basically done by hand.

If all the spinning machines and looms can be combined.Cotton spinning machines and looms were all changed to mechanical power instead of manual operation.It will greatly reduce manpower and improve production efficiency.

Then the textile industry of Ming Dynasty will immediately develop and grow stronger.

There is no need to worry about producing too much and not being able to sell it. Daming silk is an important export commodity.

In this way, the people in Jiangnan will also become rich.

Previously, the father implemented new policies in the three southwestern provinces, such as the allocation of gentry to the mu, and the integration of gentry and errands into one payment of grain. Jiangnan's policy remained unchanged, resulting in the development of the Southwest surpassing that of Jiangnan.The people in the south of the Yangtze River complained a lot, and they continued to emigrate to the southwest.Now that mechanically powered textile machines are about to appear, the economy in the Jiangnan region will soon catch up.

Mr.'s kindness first benefited Southwest, and now it also benefits Jiangnan.

"Your idea is very good!" However, Qin Yu didn't know what he was thinking, and praised, "Our Lujia Village also has many ancient looms, and the women in the village often spin their own yarn and make their own clothes."

"If we can make a textile machine powered by steam, not only can it meet the clothing needs of the whole village, but the rest can be sold to surrounding villages to increase villagers' income."

"That is to say, even if we don't have perfume, we can use looms to make Lujia Village well-fed."

"Okay, let's continue talking."

"Steam engines can be used on ships." Zhu Biao said.I was also very excited in my heart: My current seagoing ship is still powered by manpower paddling and sails.When the fourth younger brother went on an expedition to Japan, a warship had to be equipped with seventy oarsmen.

Not only is it a waste of combat power, but it is also not fast.

If he could go on an expedition to the Wa country later, and wait until Mr. invented the steam turbine... then the Ming warship must be unbridled and invincible on the sea.

Fourth brother, the expedition did not catch up with the good time!

Also, those treasure ships that go out to sea to search for gold mines are also powered by primitive power, and it takes too long to go back and forth.

"The steam engine can also be used in mining." Zhu Yingrao said.

"Sir, the steam engine can also be used to make perfume." Lu Qingqian said, "In the perfume workshop in Lujia Village, distilling is necessary, and a lot of the steam produced is wasted."

……

The speeches of the students were very enthusiastic.

"That's right, you are all thinking actively. Every student is very commendable." Qin Yu said, "After talking about the steam engine, let's talk about the steam turbine that the teacher will teach everyone to make."

"The steam engine is the first machine that uses steam as power. Its structure includes cylinders, pistons, flywheels, governors, valves and seals, all of which are the basic components of modern machinery."

"The steam engine is very troublesome to make, and the utilization rate of steam is not high."

"The steam turbine is the second-generation product that uses steam as power."

"We could call it Steam Engine 2.0"

"The structure of a steam turbine is more than ten times simpler than that of a steam engine, and it is easier to implement in our village. Moreover, its utilization rate of steam is also ten times that of a steam engine."

"Steam turbines should be the highest level of machines that use steam as power. Even large aircraft carriers and thermal power stations outside are widely used."

"Next, the teacher will teach you the working principle of the steam turbine and how to convert the internal energy into mechanical energy."

"Then let's DIY a simple steam turbine together."

"Okay!" The crowd was excited when they heard this.

……

"Yellow label!"

"exist!"

"Take out the blackboard!"

"Yes, sir."

Zhu Biao rushed into the classroom, carried the blackboard out, and put it on the shelf.

Qin Yu turned around and began to write on the blackboard, teaching while writing on the blackboard: "The steam turbine is too simple, it only needs two or three main components to complete, let's make a simple one first, so that everyone can understand its energy conversion principle. "

"First, we need to find a circular box as the body of the steam turbine."

"Secondly, find a piece of iron as the fan blade. The fan blade has this shape..." While talking, he drew it on the blackboard.

"Finally, one pipe was used to introduce the steam, and the other pipe was used to export it. To be honest, the teacher made a simple steam turbine when he was in elementary school. The teacher used pop-top cans at that time."

"Everyone says Jane is not simple?"

"Easy!" said the crowd.

"Is it easy to do?"

"Easy to do!" the students said again.

"Okay, now let's divide the labor and cooperate. The boys will find the round box, and the girls will make the fan blades, and together we will make the steam turbine model."

After half an hour, the crowd gathered all the materials.

Qin Yu led the students to start the experiment. He boiled the kettle, and the pipe was connected to the nozzle of the kettle to introduce steam. The high-temperature and high-pressure steam was sprayed onto the blades, causing the blades to rotate.

The internal energy of the steam is transformed into mechanical energy!
Amazing!

Seeing the scene in front of them, the students were amazed.

Xiaoxiao has also been watching their operations, because she is not Qin Yu's student and cannot participate in it.Looking at Qin Yu with eyes full of admiration: This man is really great.

He's so charming when he's serious.

It is the happiest thing in Xiaoxiao's life that Xiaoxiao can get her husband's mercy.

"Now everyone has made a model of the steam turbine, and they have turned the model." At this time, Qin Yu was still teaching earnestly. Simple?"

"You only need to add gears to the blades, and then use a belt to drive other gears."

"Make the airtight box bigger and add more blades to the rotor to generate powerful power. The blades should be small in the middle and large at both ends..." As he spoke, he drew it on the blackboard.

After half a day of study, the students mastered all the manufacturing methods of steam turbines.
