The Rise of the European Emperor

In this way, because of the soul of Hua Xia, Marin's guns dedicated to the Ming Dynasty to help the Hua Xia strong army were put into the warehouse to eat ash because of the personal prejudice of a senior official. As for the qualifications of the vassal state and the tribute trade, it is even more insignificant.

Malin was unlucky. After all, the tribute trade he wanted happened to be the head of special etiquette. As the saying goes, the county official is not as good as it is. Marin happened to hit the muzzle of the relevant department, and could only admit that he was unlucky ...

If these batches of guns were sent directly to the bear child Zhu Houzhao, things might change. After all, bear child Zhu Houzhao is a militant and most likes weapons.

It is a pity that after these batches of guns were sent to the Peking division, they went directly into the storeroom of the ritual department, and there was no chance to take them out. Therefore, bear child Zhu Houzhao will naturally not know.

If Marin knew that these batches of advanced guns were thrown into the storeroom of the Libe as a result of the broken copper and iron, he would definitely spit out an old blood, and then raised the knife not far away to find Mao Cheng pk ......

...

Of course, Marin is not clear about what happened on the Ming Dynasty. After all, there is no Internet or telegram to send the news back to Europe in time. Not to mention that he doesn't know now, even if Columbus's fleet returns, he won't know. Because, Columbus's fleet did not know the news of Daming after they left Guangzhou ... At this moment, Columbus's fleet is going south all the way on the South China Sea ... With the full load of cargo, Columbus and Kong Tai and others went back, It's a confession, and it's a merit ...

...

Soon after Malin came up with the second child of Felix and came up with the Chinese name of Ma Yun, the Emden Shipyard suddenly heard good news that the steering wheel was successfully developed ...

Hearing this good news, Marin immediately rode to Emden, came to the military shipyard north of Emden, and visited the newly developed successful steering wheel ...

The top part of the steering wheel, that is, the part that is pulled by the hand, is similar to the steering wheel of later generations. After all, Marin drew drawings to those craftsmen.

The lower part is made of a series of transmission rods made of bronze gears and copper rods. When steering is needed, the sailor turns the steering wheel, drives the multiple gears below, drives the copper rod, so that it uses the principle of lever to pull the underwater balance rudder ... Then, under the action of the balance rudder, the ship completes the steering ... …

However, this steering wheel system did not meet the requirements of Marin's "one person can easily complete rudder turning". After testing, this steering wheel system requires a strong sailor to complete the turn. Or, it takes two strong sailors to complete the turning of the steering wheel at high speed ...

However, this new steering wheel system is much better than the old straight rudder stock anyway. Moreover, the old straight rudder rod can turn the rudder up to 5 degrees. The new steering wheel system can turn the rudder by 30 degrees ... This greatly improves the speed of the ship's steering and enhances the flexibility of the ship ...

Therefore, Marin did not hesitate to reward each craftsman who participated in the research with 1,000 gold coins to reward their contribution.

However, Marin also said that the steering wheel system can actually be improved, and finally the steering wheel can be completed by one person. If these craftsmen can improve the steering wheel to complete the operation by one person, then Marin promises-and will also give everyone a huge bonus of 1,000 gold coins ...

...

In addition to the rudder wheel system being developed and the operation of the upper edge skewer sail, the old sailors also indicated that they were very skilled. After all, during this time, old sailors often drove a boat with an upper-edge slant sail to the sea in order to explore the control method of the upper-edge slant sail. Now, the old sailors are almost groping. For this, they also received Marin's reward ... Although not as many as the craftsmen, it was enough to surprise those old sailors ...

After all, in Europe, the status of sailors is far from being comparable to artisans. Strictly speaking, craftsmen, especially powerful craftsmen, are called masters, and they are very respectful. And the sailors ... Except for the captains and chief mates, who cares about you as a humble sailor? Columbus discovered that everyone in the Americas knew that some people might also know Columbus's lieutenant or first officer. But who knows the name of every sailor who followed Columbus to discover America?

Therefore, sailors are humble, and master craftsmen are noble. To reward the master craftsman, Marin needs to give each person 1,000 gold coins (in fact, this is also a big prize), and to those old sailors, dozens of gold coins per person, it can be easily sent, and will make those sailors grateful ...

Seeing that the two convenient R & D and testing are basically completed, Marin decided to let the craftsmen combine the two advanced technologies of the steering wheel and the upper edge truss sail on a boat ...

In the end, the R & D team used a 250-class armed merchant ship as the mother hull and converted a double-masted schooner ...

However, many problems were found during the conversion process. Among them, one of the most important issues is that the upper edge slant sail cannot be made very high ...

why? Because the quality of the canvas material at the moment is average. If it is done too high and too large, after sailing, a ride, it is easy to cause the sail to tear under the huge pressure.

In addition, if the sail is made too long and too high, when the sail is lifted, the jib on the upper edge will tear the surface of the sail because it cannot bear the weight of the lower edge girders and the main sail ...

After all, the canvas of this era, mainly linen, bears relatively limited strength. Beyond this pull range, the sail surface will tear and be damaged ...

In this way, after several failures, the shipbuilding craftsmen finally reached a conclusion that the upper edge slant sail is currently only available for medium-sized ships such as class 250 armed merchant ships. No matter how big the boat is, it can't be used ... because the sails are made higher, it is easy to tear ...

Malin was a little speechless at the same time ... At the same time, he also remembered-the sails of later generations can make such a large soft sail, because high-quality tensile materials such as strong nylon or sisal are widely used. Nowadays, the sails in Europe mainly use linen, which inevitably lacks strength.

If it's like an old-style sailing boat, it's okay to hang the sail on the upper truss. And as Marin did, ascending from below, because of the need to drag the upper edge diagonal girders and a series of copper rings, it led to the need for greater ability to withstand tensile forces. Otherwise, if you are not careful, you will tear it apart ...

Therefore, Marin needs to use higher-strength materials to make the upper edge slant sail ...

Strong nylon Marlin is not to think about, it is a modern petrochemical product. Not to mention that Marin doesn't understand petrochemicals, even if he knows petrochemicals, he can't make strong nylon without large-scale chemical equipment resistant to corrosion and high pressure ...

However, sisal is conditionally obtained ...

Right now, it seems that the sisal is still used as a companion to the cactus in the desert area of ​​northern Mexico ... As long as Marin sends people to Mexico to find, sisal can be found. After all, the shape characteristics of sisal are too obvious, as long as you see it, you can easily recognize it ...

Just find sisal and promote planting. Then, the high-strength, high-toughness, and seawater-resistant canvas made of sisal fiber should be able to be made higher and longer ... Once the sail is taller, its area is naturally larger and the ability to use wind power Naturally stronger ...

In addition, sisal is also an excellent material for making ship ropes. Even in later generations, most of the cables tied to anchors are made of sisal fiber ... It is conceivable how powerful the tensile strength of the cables of thousands of tons and 10,000 tons of ships that can be tied to later generations ... The canvas made of this kind of fiber will definitely have far more tensile strength than the canvas made of linen ...

...

But before getting the sisal ~ www.wuxiaspot.com ~ Marin can only use the relatively short upper-edge slant sail. This low-top slanted sail can only drive a small wooden boat of more than 200 tons. Even bigger, like a 500-ton warship, is a bit difficult to drive ...

Of course, it is not to say that it can't be driven at all, but even if it can be driven, the speed will definitely not be fast ...

If you drive a boat of more than 200 tons, it will barely play the role of sail, making the boat only reach a certain speed ...

...

However, for now, Marin uses this 250-ton displacement armed merchant ship to equip it with upper-edge slant sails, which is enough. Coupled with a new type of steering wheel system, a new type of brigantine was created. This kind of boat not only has strong wind-sweeping ability, but also has easy steering. Above the sea, it is very flexible ...

In particular, this flexible schooner is very suitable for north-south sailing along the American coast, which is convenient for Marin to control the American colony ...
