The Rise of the European Emperor

\u003ccontent\u003e

In this way, because of the soul of China, the guns and artillery dedicated to the Ming Dynasty to help the strong army of China were put in the warehouse to eat ashes because of the personal prejudice of a high-ranking official. As for the qualifications of the vassal state and the tributary trade, there is no shadow.

Malin was unlucky, after all, the tributary trade he wanted happened to be in charge of the Special Ministry of Rites. As the saying goes, magistrates are better off now. Marin just hit the muzzle of the relevant department, and he can only admit that he is unlucky...

If this batch of guns and guns were directly delivered to the bear boy Zhu Houzhao, things might turn around. After all, Zhu Houzhao, the bear boy, is a militant and likes weapons the most.

It is a pity that after these guns were delivered to the capital, they went directly into the warehouse of the Ministry of Rites, and there was no chance to take them out. Therefore, the bear boy Zhu Houzhao naturally did not know.

If Marin knew that these advanced guns and guns were thrown into the warehouse of the Ministry of Rites for ashes, he would definitely be so angry that he would spit out a mouthful of old blood, and then he would come to Mao Cheng pk with a knife thousands of miles away...

...

Of course, Marin had no idea what was going on here in the Ming Dynasty. After all, there is no internet or telegram to get the news back to Europe in time. Don't say he doesn't know now, even if Columbus's fleet returns, he won't know. Because, Columbus's fleet didn't know the news of Daming after they left Guangzhou... At this moment, Columbus' fleet is heading south on the South China Sea... With a full ship of goods, Columbus and Kong Tai and others went back, It can be considered a confession, and it can be considered a meritorious service...

...

Not long after Marin came up with the Chinese name of Ma Yun for Ferris' second child, a piece of good news came from the Emden Shipyard - the development of the steering wheel was successful...

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

The uppermost part of the steering wheel, that is, the part that is turned by the hand, is similar to the steering wheel of later generations. After all, Marin drew the patterns for the craftsmen.

The lower part is made of a series of bronze gears and a transmission rod made of copper rods. When it is necessary to turn, the sailor turns the steering wheel, drives the multiple gears below, drives the copper rod, and uses the principle of leverage to move 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 requirement of "one person can easily turn the rudder" as required by Marin. After testing, this steering wheel system requires a very strong sailor to complete the rotation. Or, 2 prime sailors are needed,

Only when driving at high speed can the steering wheel be pulled...

But, anyway, this new steering wheel system is much better than the old straight rudder stick. Also, the old straight tiller can turn the rudder up to 5 degrees. And the new steering wheel system can make the rudder turn 30 degrees... This greatly improves the speed of the boat's steering and enhances the flexibility of the boat...

Therefore, Marin generously rewarded each craftsman who participated in the research with 1,000 gold coins to reward their contributions.

However, Marin also said that the steering wheel system can actually be improved, so that the steering wheel can be turned by one person. If these craftsmen can improve the steering wheel to complete the operation by one person, then, Marin promises- will reward each person with a huge bonus of 1,000 gold coins...

...

In addition to the development of the steering wheel system, the operation of the upper edge gaff sail, the veteran sailors also said that they are very proficient. After all, during this period, there were often veteran sailors who went out to sea on boats with upper-edge gaff sails to explore how to control the upper-edge gaff sails. Now, those old sailors have almost figured it out. For this, they were also rewarded by Marin... Although not as many as those craftsmen, it was enough to surprise the old sailors...

After all, in Europe, the status of the sailor is far from that of the craftsman. Strictly speaking, the craftsmen, especially the great ones, are called masters and are very respected. And the sailors...except those captains and first mates, who cares about you, a humble sailor? Everyone knows about Columbus' discovery of America, and maybe some people also know about Columbus's lieutenant or chief mate. But who in particular knows the name of every sailor who followed Columbus to America?

Therefore, the sailor is humble, and the master craftsman is noble. To reward the master craftsman, Marin needs to give each person 1,000 gold coins (in fact, this is considered a heavy reward), and to those old sailors, dozens of gold coins per person can be easily passed, and those sailors will be grateful...

Seeing that the two convenient research and development and testing were basically completed, Marin decided to let the craftsmen combine the two advanced technologies of the steering wheel and the upper edge cantilever sail into one boat...

In the end, the R\u0026D team refitted a schooner with a 250-class armed merchant ship as the mother hull...

However, during the modification process, a lot of problems were also found. Among them, the most important problem is that the upper edge cantilever sail cannot be made very high...

why? Because the current canvas material quality is average. If it is made too high and too large, after the sail is raised, it is easy to cause the sail to be torn because it cannot withstand the huge pressure.

In addition, if the sail is too long and too high, when the sail is raised, the jib on the upper edge will not be able to bear the weight of the upper edge girder and the main sail, which will cause the sail surface to tear...

After all, the canvas of this era, mainly linen, was limited in strength. Exceeding this tension range, the sail surface will be torn and damaged...

In this way, after several failures, the shipbuilders finally came to a conclusion - the upper edge gaff sail is currently only used for medium-sized ships such as 250-class armed merchant ships. No matter how big the boat is, it can't be used...because, no matter how high the sail is, it is easy to tear...

Marling was a little speechless for a moment... At the same time, he also remembered - the sails of later generations can make such a large soft sail because of the extensive use of high-quality durable materials such as strong nylon or sisal. But now European sails are mainly made of linen, which is inevitably insufficient in strength.

It would be nice if the sails were hung from the upper spars, like an old-fashioned schooner. However, as Marin did, if he ascended from the bottom, he would need to have a greater ability to bear the pulling force because he needed to drag the upper edge slant girder and a series of copper rings. Otherwise, if you are not careful, it will be torn apart with a 'scoff'...

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

Don't think about strong nylon marlin, which is a product of modern petrochemicals. Don't say that Marin doesn't understand petrochemicals, even if he understands petrochemicals, he can't make strong nylon without large-scale chemical equipment that is resistant to corrosion and high pressure...

However, sisal can be obtained conditionally...

Right now, sisal seems to be still with cacti in the desert north of Mexico... As long as Marin sends someone to Mexico to find it, sisal can be found. After all, the shape of sisal is too obvious, as long as you see it, you can easily recognize it...

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

In addition, sisal is an excellent material for sea-boat cables. Even in later generations, most of the cables that tie the anchors are made of sisal fibers... It is conceivable that the cables that can tie the thousand-ton and 10,000-ton ships in the future will have such a strong tensile ability... Canvas made of this kind of fiber must have far more tensile strength than canvas made of flax...

...

But until sisal was available, Marin had to settle for a relatively short top-rigged sail. This kind of short upper edge cantilever sail can only drive a small wooden boat of about 200 tons. A bigger one, like a 500-ton warship, would be a little harder to drive...

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

And if you drive a small boat of more than 200 tons, you can barely play the role of the sail, so that the boat can only reach a certain speed...

...

However, for now, Marin's use of this 250-ton armed merchant ship with a top-edge gaff sail is enough. Together with the new steering wheel system, a new type of schooner was created. This kind of boat not only has a strong ability to grab the wind, but also is very convenient to turn. Above the sea, very flexible...

In particular, this kind of flexible schooner is very suitable for north-south sailing along the coast of America, which is convenient for Marin to control the American colonies...\u003c/content\u003e
