Chapter 1854： Weak chicken version of the magic change "big fly"

What speed is 7 knots? That ’s 7 nautical miles per hour. And each nautical mile is 1.852 kilometers, that is to say, the speed of 7 knots is 12.96 kilometers per hour ...

What's so special, even if the speed of the bicycle on the road can reach 20 kilometers per hour, this speed is also unpleasant?

However, think of Marin, a person who has seen the world. In the eyes of others, the speed of 7 knots is indeed remarkable. At least, in riverboats, this speed is very fast. You should know that in this era, the ships on the sea, because of the strong sea breeze, were able to sail downwind at most 10 knots. Only a narrow and long speedboat can run at a high speed of 12 knots.

But it was at sea and the wind was strong. In the interior, the wind is not even as good as the Mediterranean. Therefore, riverboats are generally very slow. Even if a paddle sailboat is used, because of the limited human power, it is impossible to row heavy oars, and the boat can only be drawn at a speed of five or six knots. It's not impossible to draw a speed of 7 knots, but it is usually an empty boat, and the oarsmen don't want to move. However, such a paddle cannot last forever, after all, people cannot do this for a long time at high speed. Therefore, under normal circumstances, the speed of paddle sailing is difficult to reach 7 knots.

Is a Calais boat. With the breeze being powered by sails and the oarsmen paddling together, it can reach a speed of 7 knots. But under normal circumstances, paddlers also need to save their physical strength, not to explode often. Such a speed can only erupt when the naval battle escapes or chases.

Therefore, in the face of a "speedboat" that can steadily drive out at a speed of 7 knots, everyone else is amazed, thinking that it is simply a miracle of God.

"Is this a miracle? I really don't know ..." Marin's eyes rolled and he decided to make a fierce one.

So, he called Da Vinci and ordered:

"How many sets of this diesel engine and propeller system do you have?"

Da Vinci replied:

"10 sets are all qualified diesel engines selected by me and my students after improvement."

In fact, the craftsmen in Beihai have produced more than 100 12-horsepower single-cylinder diesel engines. However, because of the manufacturing process and various improper operations, in the end, Da Vinci and his mechanical college students only selected 10 qualified products. As for the propeller system, that's nothing. Twenty sets of nickel steel transmission rods and propeller blades have 12 sets, which is almost half of the pass rate.

"10 sets, right ... Ha ha, Ada, I will teach you a fun one, make the boat faster!"

Da Vinci was confused, Marin suddenly asked again:

"Ada, do you know" Dafei "?"

"Da Fei? Who is it?" Da Vinci was confused.

"Ah, it seems that he is not a passer-by, and he doesn't know‘ Da Fei '... "

So, what is "Dafei"? It is actually a speedboat for smuggling. The average speedboat has a speed of 30 to 40 kilometers per hour. However, as a "big fly" of smuggling speedboats, in order to escape the interception of anti-smuggling ships, the speedboats are often modified to make the speed of the speedboat very high.

The method of modification is also very simple-six or even seven 250-horsepower boat hooks are installed side by side at the tail of the speedboat. In this way, the six boat hooks work together to push the speedboat to a very high level.

Generally speaking, a "big fly" equipped with a car or more than 300 cases of cigarettes can run at speeds over 90 kilometers per hour. Because of the resistance of the water during high-speed navigation, speedboats often break through the obstacles of the water and "fly" on the surface of the water, so it is also called "big flight".

The flying speed is too fast, and the speed of more than 90 kilometers per hour can be put on the land to get high speed. The speed of anti-smuggling ships at sea is generally about 60 kilometers, with a maximum speed of 80 kilometers per hour. Encountering this kind of unreasonable is a "big fly", there is really no way.

However, after China had money, the customs department had sufficient funds allocated to it. The shotgun was replaced with a gun. He was equipped with a helicopter ... Nima, how fast can you "fly" and get past the plane? Then, "Dafei" was restrained by "Zhenfei (machine)" ...

Of course in this era, everyone has not seen the power of "Big Flying". Marin smiled mysteriously and began to instruct Da Vinci and his mechanical students to transform the hull. In a dozen-ton boat, four 12-horsepower single-cylinder diesel engines are hung directly at the stern ... This is still a small boat. In addition, the diesel engine needs a crank handle to start, so it has to make room. Otherwise, Marin intends to install 6 at a time ...

After the four diesel engines were installed, Marin ordered the four mechanical students to shake the crank together to start the diesel engine. Then, the gear ... Of course, there is only one gear, and the other is in neutral ...

After the gears were locked together, the speedboat rushed out quickly with an arrow off the string. The knots and empty barrels used to measure speed behind were also quickly dragged away ...

Da Vinci and a group of mechanical students directly Sparta ...

"How much speed?" After a while, he saw that the rope and the empty barrel had been pulled away, and he began to question the record.

"Probably ... up to 18 sessions?"

"How much?" Da Vinci thought he had heard it wrong, grabbed the record book, and glanced at it-no problem, verse 18 ...

At this time, Marin realized that it was wrong and ordered—

"Hurry, catch up with horseback and order to stop the boat with a horn!"

This small river for the mechanical system to test the speed of the ship is only a few dozen kilometers long, but it can't stand the ship's "random run" ...

As a result, still a step late, the "speedboat" rushed to the beach at the end of the river at a speed of 18 knots. The four mechanical students responsible for sailing were all injured, but fortunately they were not too serious. But the hull of the wooden boat crashed directly, even the two diesel engines were broken ...

Da Vinci calmed the injured students and sent them to the hospital, excitedly dancing:

"If the ships are equipped with this kind of power, who can catch up with the ships of the North Sea country?"

Marin poured cold water on him:

"Don't dream, Ada, diesel is not enough ..."

It is true that now the North Sea country can only import oil from the Galician valley in Poland, and it will soon obtain oil from the crater on the island of Taiwan.

However, even so, oil production is still low ...

The oil production in the Galician Valley is very low, only one or two barrels per day, which is the output after Marin invested heavily. The scope of the sulphur pit has been determined, but it is still under exploration. Moreover, it is necessary to wait for the Zhuojing well to open before mass production.

The Persian side, according to the information returned, that the Baku region can indeed produce hundreds of ships of oil every year, but there are dozens of ships that Marin can buy. Because the Middle East also needs oil to treat skin diseases for cattle and sheep ...

Therefore, while Marin needs to vigorously develop new oil fields, he intends to negotiate with the Persian side to actively invest in the development of the Baku oil field and dig a few more deep wells to obtain more oil ~ www.novelhall.com ~ Petroleum, this kind of magically modified "big fly" can really be put into use ...

However, to say that it was "Da Fei" really insulted the name of "Da Fei". Because the speed of this boat is too low ...

In the 18th quarter, watching the bluff, its real-time speed was only 33.3 kilometers, which was a little faster than the electric bicycle after the speed limit. Of course, this is also related to the speed of the diesel engine is not as fast as that of the gasoline engine.

In addition, this diesel engine as a hook is too cold ...

The real "big flying" of others, all hang 250 hp imported marine hook, the power is extremely strong. And the weaker version of Marin's magical change is flying, and the 12-horsepower single-cylinder diesel engine is hung, and the single power is only one-twentieth of others ...

Therefore, people's true "big flying" can "fly" on the sea. The weak chicken version of the magical change made by Marin can only be rushed in the river ...

However, the speed of 18 knots really shocked the indigenous people of this era. Even Leonardo da Vinci was a little shocked. If they were allowed to evaluate this "weak chicken version of the magic change to big flying", they would definitely agree with the title of "big flying". Because, in the eyes of these indigenous people, the speed of 18 knots is equivalent to "flying" ...

(I guess this speed of 18 knots, but I have n’t tried it, mainly because I have n’t tested it)
