My Daming New Empire

Just behind this row of houses, between the two rows of houses, there is a large warehouse.The door of the warehouse was locked tightly. From Ma Zhicai's point of view, it hadn't been opened for at least half a year.

The little eunuch named Liu Wan took out a key and tried several times before opening the copper lock.

Then the two young eunuchs pulled open the two iron doors together.

Zhu Zhanji looked at the door. Although the bonus hadn't been opened for a year, because the room was relatively closed, there wasn't much dust inside.

Li Liang said softly: "Your Highness, let's clean up first, before you come in!"

"It's okay, I'm just showing the Deputy Ma to look at the environment, let him know what to do in the future, and be prepared."

When Ma Zhicai saw the scene in front of him, he couldn't believe his eyes. He thought it was a warehouse for storing some items, but he didn't expect that it was a carpentry workshop.

Except that the tools are more delicate and some tools are different, the furnishings here are not much different from his own workshop.

Moreover, the furnishings inside are a bit messy.All kinds of wood, all kinds of different models made, piled up everywhere.

Does His Royal Highness have a hobby of carpentry?He thought so for the first time, but he denied it again, because there had never been any rumors about it!

When he took a closer look, he found that he hardly knew all the models in it, and he couldn't tell what the various woods were used for.

In the corner of the room, he also saw a huge triangular kite, but it didn't have a tail, and he didn't know if such a kite could fly into the sky.

Zhu Zhanji walked to the front of a large cabinet, took out the key with his own hands, and opened the door. "Take out everything inside and put it on the workbench."

Several young eunuchs cleaned the table, and then took out the items wrapped in various cloths in the cabinet. There were various items, and Ma Zhicai couldn't tell what they were.

Then, Zhu Zhanji waved to him, and he quickly walked up to him, held his breath, and watched Zhu Zhanji open these cloth bags.

The first thing Zhu Zhanji took out was a ruler, which was about three feet long and marked with small straight bars.

Then, another square, and then a wooden compasses, vernier calipers, and other measuring tools.

Compared with other experimental products in the room, Zhu Zhanji attaches the most importance to the simplest tools, because these are the basic standards for industrial development.

It's just that if you want to promote these standards, you can't directly come up with the standards of later generations. He must improve and integrate them on the basis of today's measurements, so that everyone can accept them.

The meter of later generations was originally one ten millionth of the distance from Paris to the North Pole, and later changed to about one 30th of the speed of light.

Of course, Zhu Zhanji would not and could not adopt these two standards, so he directly adopted the current Daming measurement standard.

There is no standard for rice in Ming Dynasty. From large to small, they are li, yin, zhang, chi, cun, fen, centimeter, centimeter, silk, suddenly, micro, and xian.

Except for the citation of the fifteenth system, the rest are in the decimal system. In fact, this standard is not much different from that of later generations.

However, the only thing missing is the meter, the most commonly used and easiest dimension to measure.

Moreover, there is not much difference between the li in the Ming Dynasty and the later generations, which is about 530 meters in later generations. This standard has been handed down according to the Zhou system and has a very broad mass base.

Therefore, Zhu Zhanji does not need to come up with the standards of later generations, but only needs to add two measurement units on the existing basis.

These two units of measurement are kilometers and meters.

Adding these two units of measurement, the measurement of the entire length, forms the complete decimal system.

Although the current rice is about [-]% longer than the rice of the later generations, the rice of the Ming Dynasty can become the general standard of the later generations before the rice of the later generations appears.

Ma Zhicai is in this business, so Zhu Zhanji just said it briefly, and he fully understood it.And according to the meter standard, it is easy to convert the new standard of area, plot and volume.

Because it is a complete decimal system, it is easier to calculate than the original standard when calculating.

Zhu Zhanji then said: "I need you to formulate precise meters, decimeters, centimeters, and millimeters in strict accordance with the existing Li standards. It shouldn't be difficult, right?"

Ma Zhicai bowed and said, "His Royal Highness has already given the criteria for classification, and the minister is just a simple characterization, there is no problem at all."

Zhu Zhanji nodded and said: "Since Emperor Qin unified the world's weights and measures, in the past 1000 years, the weights and measures have been expanded repeatedly. The original one zhang was only a little more than two meters, but now it has reached more than three meters. We are now going to formulate a decimal system. Metrics, and common throughout the country, or even the world."

Ma Zhicai asked: "Your Highness, Weichen is just a craftsman. Although he can make a meter stick that meets His Highness's requirements, Weichen seems to have no ability to promote it."

Zhu Zhanji shook his head with a smile and said: "No, you don't need you for the promotion, you don't even need you to formulate this standard. I let you be familiar with these now, just want you to help me make some models that meet my wishes. Please contact me I come……"

Coming to the glider he made himself, Zhu Zhanji sighed and said: "This is a big umbrella made after the wings of a bird. I hope it can fly into the sky, but there are still many unqualified parts. So I hope you can help me finish it."

God...

Ma Zhicai was a little speechless, if the person in front of him was not a grandson, he would have wished to denounce it as whimsical.

Since ancient times, all human beings have dreamed of going to heaven and earth, but until now, no one has been able to achieve it.

Just 20 years ago, in the 28th year of Hongwu, there was a rich man named Wan Hu.He installed 47 of the largest rockets that could be bought at the time on the back of a seat.Then he tied himself to a chair and held a big kite in each hand.

The bird-shaped aircraft was placed on the top of the mountain, and Wanhu asked people to ignite 47 rockets at the same time. The purpose was to use the power of the rocket to propel it forward, coupled with the rising force and balance of the kite, to fly into the sky.Then, the flame-breathing "flying bird" led Wanhu away from the mountain and rushed into the air.But soon, the fire disappeared, and the bird rolled and fell to the foot of the mountain, and Wan Hu died.

He said in a trembling voice: "Your Highness, such a behavior is risky. Your Highness is a daughter of gold, so you must be careful."

Zhu Zhanji said with a smile: "Gu just wants you to perfect the wings, and didn't say that Gu wants to go to heaven."

He hesitated for a while, looked around the wing for a while before asking: "I see that this wing is exquisitely crafted and the materials used are exquisite. I don't know where it needs to be perfected?"

"The strength of the main control rod and the toughness of the connections between the various parts."

In his previous life, Zhu Zhanji had nothing to do with paragliding and hang gliding several times.Don’t think about paragliding, because there is no windproof cloth that can be used to make paragliders. It needs to store air and design wind flow guidance. Zhu Zhanji knows it and doesn’t know why.

But the hang glider has a simple structure, so the control is much simpler.The key problem now is that the material technology cannot be achieved.

The fabric of the hang glider can be the buttercup silk produced in Nanyue today.This kind of Ranunculus silk adopts the original technology, using domestic silkworm silk as raw material, and after weaving it into plain fabric on a jacquard hand-held machine, it is dipped and dried with the tuber juice of a unique plant - Ranunculus yam for many times, so that the fabric adheres to it. A layer of yellow-brown jelly.

Then use pond mud containing high-priced iron ions to evenly coat the surface of the fabric, and after repeated drying and washing, it is made into a fabric with black front and brown bottom. It is an expensive silk product and is regarded as the first-class Chinese silk. Excellent product

This kind of butterscotch silk has been repeatedly refined through six steps and 36 processes, and its windproof, waterproof, toughness and tear resistance have all reached a very high standard.

The cloth problem has been solved, but the material and technology of the main frame of the hang glider and the material technology of the main load-bearing bracket are difficult to solve in this era.

It is impossible to use steel products, because it is impossible to fly with this weight.However, instead of steel products, wood or bamboo is used. When encountering strong winds, the compressive capacity cannot meet the standard.

So this model Zhu Zhanji has been manufactured a long time ago, but it cannot be used.

In addition to this hang glider, there are also bearing models made by him in this warehouse. This is the most important accessory in the industrial age. Bearings are indispensable for almost all transmissions.

But if you want to make bearings, the most important thing is the manufacture of steel balls and the grinding of the slots. This requires not only the craftsmanship, but also the improvement of materials.

Zhu Zhanji also counted on Ma Zhicai to make some inverted casting molds to solve the process problems.

In addition to these, there are also models such as simple transmission lathes and drilling machines, which require Ma Zhicai to manufacture samples first.

And Ma Zhicai saw this, although many things didn't know their functions, but he also understood that this was what he was interested in.

Breaking away from the strife in the officialdom, you can still get the appreciation of your grandson, and you can do things you are interested in.
