Chapter 1855： "Da Fei" and "Dover"

This magically modified "Big Flying" scene of "flying" on the water leaves an indelible impression on everyone present, and it is very shocking. But after calming down, he was thinking about a question-what is the use of this magical change?

You said it would be useless to take the combat handle, and the speed of the ship alone would be useless. After all, the ship was not used to collide with people. Even if you catch up, you must rely on firepower to solve your opponent. The warships of the North Sea countries are not slower than warships of other countries, and they can catch up on their own. Using a diesel engine seems not very cost-effective ...

If it is used as a speedboat to transmit information ... no matter how fast the boat is, the pigeons fly fast ... If the transatlantic distance is too long, the pigeons can hardly reach the place, you can use this big fly, that is , It's too special!

According to estimates, this 12-horsepower single-cylinder diesel engine from Marin makes a cottage that consumes two to three liters of diesel per hour. If four engines are juxtaposed, it will consume 11 or 12 liters of diesel per hour. If you run 10 hours a day, a big fly will cost more than 100 liters of diesel ...

But for the current Marin, diesel is in short supply. The current reserve is only 10 barrels of diesel, which is about 1590 liters, which can't stand the consumption of several "big flying".

If it is a simple message, Marin might as well get out of a flying shear boat. That way, at least it doesn't consume fuel. Want to really use diesel engines, unless there is a major role. For example, for naval warfare ...

"Okay, let's play bigger this time and put the diesel engine on the battleship directly!" Marin Fudged Da Vinci and one of his disciples went crazy.

Everyone came to the secluded William Junction and started the warships anchored in the harbor ...

First of all, the rudder blade placed in the middle of the stern must be modified. Because, according to the standards of Dafei, the rudder blades are likely to conflict with the parallel propellers in the middle. Therefore, the rudder blades can only be placed on both sides.

Fortunately, this problem is not too big. As long as there is a rudder wheel system, an extra effort-saving lever system combining fixed and moving sheaves can be used to place the rudder blades on both sides of the stern. Then the captain stood in the middle of the stern and pulled the steering wheel.

Then, the diesel engine was installed. A 250-class armed merchant ship with a width of seven or eight meters. Marin installed eight 12-horsepower single-cylinder diesel engines in a space of one meter.

Next is the test ...

Is different from the inland river boat test, after all, it is a big boat with a displacement of 250 tons. Eight 12-horsepower diesel engines have a total horsepower of only 98 horsepower, and in future generations, people start fishing at 150 horsepower ...

The results were tested. Without raising the sails, eight 250-class armed merchant ships driven by 12 horsepower diesel engines had a speed of only 8 knots.

However, if the sail is hung and two kinds of power are added, the wind can run at a speed of more than 13 knots ...

Headwind or no wind ...... The speed of 8 knots is the king!

After transforming the 500-ton warship, this effect is even worse. After all, the tonnage has doubled, but the power has not changed ...

In fact, 12 single-cylinder diesel engines can be placed on a 500-ton battleship. However, Da Vinci and his mechanical students only had a total of 10 useful hands, and two of them were destroyed. Currently, only 8 can be used for testing.

96 horsepower to drive a 500-ton ship, naturally very difficult. In the windless state, the speed of the 500-ton class warship is only more than 4 knots ... This assistance is not as good as the paddling of others with paddlers ... Even if it is filled with 12 single-cylinder diesel engines, Marin estimates that the windless speed will be More than 5 knots, meaningless. No way, the ship is too big, the diesel engine power is too small ...

Marin wanted to improve the power of the diesel engine, but unfortunately, he had never learned mechanics in his last life. Knowing the principles of internal combustion engines is taught in middle school textbooks. It can be known that the structure of the single-cylinder diesel engine is remembered by the old tractor repairing the walking tractor at home. As for the design principles of diesel engines, how to improve power ... sorry, we are not professionals ...

As for the scientific master Leonardo, his power calculation formulas such as the kinetic energy equation are still learned from Marin, and he is expected to improve ... If Da Vinci is 20 years younger, he may still expect ...

But anyway, the standardized 12-horsepower single-cylinder diesel engine is there. As the mechanic department trains mechanics one by one, there will always be excellent mechanical ones that can improve diesel engines.

Marin knows that if the diesel engine wants to achieve high power, it must use multiple cylinders. However, he is not even clear about the principle of multi-cylinder steam engines, let alone diesel engines? Therefore, he can only write such a sentence in the teaching material of the Da Vinci Mechanical Department-

"According to the great sage Saint Einstein, if the cylinder is increased, it is estimated that the power and performance of the steam engine and diesel engine can be improved!"

As for the rest, Marin can only count on another genius like Da Vinci among mechanical students who can design a multi-cylinder diesel engine with high power.

For this, Marin gave a very high reward-who can make a multi-cylinder steam engine or diesel engine, reward 10,000 gold coins, an unhereditary knighthood!

This is a very high reward. A great **** like Newton is only a jazz to his death, or because he became the governor of the Royal Bank of England. Others, not from the nobility background, have almost no shortcuts except to go to the battlefield to gain military credit.

Therefore, Marin's reward is actually exceeding the standard and very attractive.

But Marin knew that this reward was really nothing compared to the benefits. It should be known that once the steam engine realizes the double-cylinder linkage, it can be applied to the train so that the train can run at a speed of 20-30 kilometers or even 40 kilometers per hour. When applied to a ship, it can also make the ship run faster than a dozen knots.

If the diesel engine can achieve multi-cylinder linkage, it is even more remarkable. Its extremely fast speed will make people enter the era of internal combustion engines, and the speed will be greatly improved. The most important thing is to make diesel-powered cars appear and change the way people travel.

Marin began to regret that he hadn't tested a mechanical department in his last life. I knew I had to go through it, so I learned a double degree in history and mechanics ...

Back then, he had three plus two in the college entrance examination, and the number of words + any two of them was optional. For example, candidates can choose a wonderful combination of physics + history ...

Later, I thought that although this model was user-friendly, it was not convenient for management teaching, so I changed it later ...

You should know that the students who chose courses in the liberal arts and sciences at that time, if they chose physics + history, they may take classes in the science class in the morning and go to the liberal arts class to study history in the afternoon. . But how can students beat school? Therefore, it is normal that this humanized model of elective courses be cut off later ...

Uh ...

In fact, Marin has been able to bring the simplest single-cylinder diesel engine to this era, which is already great. Because this has simply disturbed the development of the normal science and technology tree in the world.

Know that even a walking tractor is quite a match. Not to mention the efficiency of arable land, even running on the road, you can also run a speed of more than ten or twenty kilometers per hour, without having to rest, and explode the horses. Moreover, the cargo capacity is much larger than the carriage.

In addition, the head of the single-cylinder diesel engine is also a universal item. He can drive the rice mill to mill the rice, the steel grinding surface, and the water pump to irrigate ...

Well, with specially designed suspension equipment, it can also act as a harvester, which is much faster than people ...

The only problem is that the oil extraction technology is backward and unable to get enough oil ...

Uh ...

Therefore, after thinking over and over again, Marin did not feel the need to install a diesel engine on a 500-ton battleship. Because these warships are enough as long as they are not slower than enemy ships. In terms of firepower and perseverance, who can compare with the battleship of the Galen ship, which has been in the leading epoch of the North Sea for tens of centuries?

However, it is feasible to install diesel engines on 250-class armed merchant ships. Because, the windless speed of 8 knots ~ www.novelhall.com ~ is also very fast in this era.

Although fast speed is useless under normal circumstances, it is very valuable if you learn Bideus ’s fighting tactics ...

If eight single-cylinder diesel engines are installed at the stern of a sail paddle boat designed by Beihai State, after the war, how fast is this sail paddle boat? Even in a windless area, it can soar 8 knots, faster than the Calais. If the paddler took a few more strokes ... that speed is estimated to reach 10 knots.

When it comes to maneuverability, who can compare to the 250 modified sail paddle boat? Coupled with the power of the lizard cannon in front of the sail paddle boat, you can use Bideus's tactics to the extreme ...

"Well, that's it. I selected a few 250-class armed merchant ships, modified them, and added 8 single-cylinder diesel engines. Since the French kind of ship is called the Calais, then this kind of ship is called Dover ... ... "Marin decided.

Dover is the port of England directly opposite the port of Calais. The two ports jointly guard the narrow Calais Strait (known as the Dover Strait by the British).

Since after all he wants to stand on the side of England, Marin naturally stands in the perspective of England to consider the problem. Moreover, this ship is also designed for Calais.

In the future, regardless of whether the Calais ship can hit the English ship, Malin has installed 8 single-cylinder diesel engines on the Dover ship, and the French Calais can not escape the custody ...
