The list and quotation that John sent back from the United States were reviewed one by one to find the companies he needed. Pen | fun | pavilion www. ｂｉｑｕｇｅ。 ｉｎｆｏ

Nowadays, it is impossible for Fengtian to need various types of industrial projects as at the beginning, as long as the price is cheap, they will be drawn in, and the current industrial categories owned by the north are almost perfect.

That is to say, Fengtian has reached the stage of picking and choosing, and will only choose more advanced technologies.

If there is a good project, he will naturally not let it go, and if there is no project that is needed to seal the sky, he will not throw money out stupidly.

What Fengtian needs to do is to pick up the missing pieces and fill in the gaps and further improve the industrial system of the Northland.

Not to mention, in the materials sent by John this time, there are really some good categories, as well as some projects that belong to leading technology.

Just when Feng Tian carefully sifted through these lists and had not yet made a final decision, John sent another telegram: "Dear Feng, there is a message that I don't know if you will be interested. The aircraft carrier ordered by the US government, due to a shortage of funds, decided to terminate the continuation of additional funds to the shipyard and stopped the two existing aircraft carriers under construction. If you're interested, give us a call, or, wait for William to arrive, and then decide. Or maybe I'm thinking too much, after all, you don't have a port yet, hehe. ”

Nima, there was such a change, but it was beyond Feng Tian's expectations.

The little butterfly was in a mess, and it really played a role.

In 1934, what aircraft carrier was being built by the United States, did Fengtian not know?

Hehe, the US government is so poor that it can't even afford to build an aircraft carrier.

It seems that in the post-silver market trading, the U.S. government operation has failed.

But who has that much energy to inflict such a loss on the US government?

This point is incomprehensible to Feng Tianbai.

From John, Feng Tian learned that the silver market is still fighting fiercely, and there may be a lot of money active in it.

Of course, John didn't know who was making waves in the market.

Since there is a lot of money active in the silver market, the silver market can't stop for a while, and the funds in Fengtian can also find some mosquito legs in it, although there is little meat, it is also meat.

However, Fengtian will never invest too much money to toss.

First, Fengtian has already made quite a lot of profits and doesn't want to take any more risks. It's not just quite a profit, it's a huge profit!

In the silver market, Fengtian entered from the price of $0.25 per ounce, and when it came out, the price was already at a high level of three or four dollars.

Moreover, his profit is mainly pushed up by others, rather than pushing up the price himself, and it costs almost nothing.

Second, Feng Tian doesn't want to expose himself, and if he eats such a large profit, he will be hated.

Although Feng Tian was very rude in doing things, he was very careful to hide himself, not to shoot on the ground, and quietly drip into the city.

This time the United States is calculated, Feng Tian knows that the consequences are unpredictable, the Americans have suffered a big loss, and they probably will not give up, and the CIA will definitely secretly investigate who is making waves in the silver market.

Therefore, Feng Tian asked William and John to eat a little chip at the bottom, make a little profit and leave, and never returned to the silver market after that.

Of course, the big money tossed in the silver market just provided cover for Feng Tian and became a real scapegoat.

As for how the Americans will treat them, it has nothing to do with Fengtian, and they can watch the excitement from the sidelines.

This time he made a fortune by operating silver, and from now on, Feng Tian will never worry about money again.

With hundreds of billions of funds in his hands, who is afraid of Feng Tian?

As for the purchase of aircraft carriers, it is drizzling, tens of millions of dollars, is it still money here in Fengtian?

Feng Tian is of course interested in aircraft carriers, although there are no ports that can dock aircraft carriers yet.

However, the absence of a port now does not mean that there will be no in the future.

In the history of the US Navy, the aircraft carriers under construction at this stage are precisely two Yorktown-class aircraft carriers.

And one of them is the aircraft carrier Enterprise, which is actually translated as "enterprising" and "endeavor" would be better, but for various historical reasons, it is translated as "enterprise" in China.

The ship was approved for construction on August 3, 1933, construction began on July 16, 1934 at the Newport News Shipyard in Newport News, Virginia, was launched on October 3, 1936, and commissioned on May 12, 1938.

When completed, it had a standard displacement of 19,800 tons and a full load displacement of 25,500 tons. The length of the ship is 246.7 meters, the flight deck is 33.4 meters wide, the waterline is 232 meters long, the waterline is 25.4 meters wide, and the draft is 7.9 meters. 9 boilers, 4 Parsons steam turbines, 4 shafts, and the main engine output is 120,000 horsepower.

The Enterprise aircraft carrier has a maximum speed of 32.5 knots and a cruising range of 12,500 nautical miles / 15 knots.

The aircraft carrier is armed with 8 single-barreled 127-mm guns, 4 4-pack 28-mm machine guns, and 24 12.7-mm anti-aircraft machine guns. There are about 90 carrier-based aircraft. In 1941, there were 2,217 staff.

Just look at the data, the current aircraft carrier is only 20,000 tons, which is too small.

This is not a nuclear-powered aircraft carrier in later generations, the 100,000-ton level, now is the era of conventional power, and it is impossible to have too much tonnage.

Besides, the jet age hasn't arrived yet, and the flight deck doesn't need to be too long.

The greater the tonnage of the aircraft carrier, the higher the technical difficulty, including in later generations, the tonnage of aircraft carriers was also limited to less than 120,000 tons.

Why is the aircraft carrier limited to less than 120,000 tons in full displacement?

Actually, this is a very simple reason, and it is not worth discussing.

Isn't it more powerful to build aircraft carriers to more than 300,000 tons?

That's a fool's dream, I don't know about ships at all, I don't even know about steel structures, I just talk about it by imagination.

The construction of aircraft carriers also developed in a gradual way, and it was not the 100,000-ton level of later generations.

At the beginning of World War II, the aircraft carrier was only more than 20,000 tons, and later it was 40,000 or 50,000 tons, because the jet planes needed relatively high take-off and stall speed limits, so the deck and ejection area needed to be longer than before, and the aircraft carrier was expanded to more than 50,000 tons.

Even in later generations, that is, the Americans had deep pockets, and in order to maintain their superpower, they expanded the aircraft carrier to more than 100,000 tons.

And this has basically reached the limit, and the aircraft carriers of other countries have not yet had a full displacement of more than 80,000 tons.

In the final analysis, an aircraft carrier is a mobile airfield on the sea, which already explains the essence of aircraft carriers:

1. The aircraft carrier is a special floating airfield on the surface; 2. The aircraft carrier must maneuver, and it must maneuver at high speed;

Since it is an airport, the main function is to retract and release aircraft, the most important area of the aircraft carrier is the deck, and the design of other ships can first determine the tonnage according to the power parameters, and then design the cabin and armament;

The aircraft carrier is a special case, the aircraft carrier is to determine the performance parameters of the carrier-based aircraft first, and the deck parameters are determined according to the performance of the aircraft.

The reason is very simple, in the era of propeller aircraft, the aircraft carrier deck (total length) can be as short as 200 meters, and in the era of fixed-wing jets, the aircraft carrier deck (total length) cannot be less than 200 meters in any case, otherwise, whether it is ejection or slip jump, it is impossible to take off conventional fixed-wing carrier-based aircraft;

Therefore, the design of the aircraft carrier is to first determine the carrier-based aircraft, according to the carrier-based aircraft parameters backwards to the deck parameters, and then according to the deck parameters, determine the overall layout of the cabin, and finally determine the tonnage and power system parameters.

Regardless of which type of carrier-based aircraft is carried and which kind of carrier-based aircraft is better to release and recover the aircraft, the smaller the speed difference between the aircraft carrier and the carrier-based aircraft, the better, that is to say, the smaller the stall speed of the carrier-based aircraft (the minimum take-off speed is proportional to the stall speed), the better, and the long-term maximum speed of the aircraft carrier, the higher the better;

And both of these have limits.

In later generations, the stall speed of modern jet aircraft, and the take-off speed, were at least 120 to 200 knots;

In later generations, whether it is steam, gas or diesel large ships, the maximum sustained speed is between 25 and 35 knots, and the long-term high speed of the aircraft carrier when retracting and releasing carrier-based aircraft, under low sea conditions, 30 knots is basically the limit, and in the windward state, there are more than 30 knots of deck wind, which is completely sufficient.

If you want to increase the speed, it is basically impossible.

Because of the draft conventional monohull large ship, its maximum speed, each unit increased, the maximum power of the main engine required is almost between the quadratic and cubic of the original unit.

In other words, it is impossible for a conventional ship to increase its maximum speed without restrictions.

This requires an exponential increase in powertrain power, which is not possible with the current human internal combustion engine and steam engine systems.

There is an exponential relationship between the maximum speed of large ships and the power output, and 27 knots is basically the minimum threshold for modern aircraft carriers.

There is basically no large ship with a full displacement of more than 50,000 tons that can exceed the maximum speed of 35 knots, and there is no civil ship that exceeds 30 knots.

In later generations, modern large civil ships with continuous high speed, generally container liners, can reach a cruising speed of more than 20 knots, and the most advanced sustained speed can reach 25 knots, which is already the highest speed of large ships galloping at high speed on the ocean.

Because the timeliness of container cargo is relatively high, the speed of this kind of large ship is relatively fast, this kind of container liner, Panama class in 5 to 70,000 tons, over Panama class is more than 80,000 tons, the largest container fast ship, about 100,000 tons, hull width of nearly 50 meters, length of more than 300 meters.

Just looking at the hull, it is basically similar to the size of the American supercarrier, wide body, and length.

It's just that the deck of the aircraft carrier is relatively large and wide, and the width of the waterline under the deck of the aircraft carrier is also between 45 meters and 50 meters, which is very similar to that of a container liner, and both have a bulbous bow that wears waves;

The overall ship type and size of the super container liner are similar to those of the supercarrier, which can cruise at high speed with more than 25 knots, and the power power is also similar.

Mixed military-civilian shipyards that can do super container liners have the potential to make supercarriers.

Regardless of whether the aircraft carrier is a civilian clipper, the full hull of 100,000 tons and the speed of 35 knots are already the current technological limit of mankind, and if you want to achieve more than 100,000 tons and ships of more than 35 knots, at least you can't do it in a short time.

If the aircraft carrier is more than 300,000 tons, then this is equivalent to the hull size of a supertanker or a superore ship.

That is to say, the length-to-width ratio basically cannot exceed 7, that is, the length of the ship does not exceed 350 meters, and the width of the ship is generally 60 meters or even more.

This fat boat, no matter what the power system is on, will not exceed the top speed of 25 knots.

The same supertanker and ore ship, the maximum cruising speed is only about 15 knots, or even lower, because the timeliness of these goods is not strong, and it is acceptable to go slower. Technically, it can't be done either.

If a 300,000-ton aircraft carrier is so fat and so slow, not only is it difficult to retract and release the aircraft, but such a slow and soaring speed is simply a target for conventional submarines, let alone nuclear submarines!

Some people say, why should the ship type be so fat, a 300,000-ton ship, can't it be 50 meters wide and more than 400 meters long, and sail at high speed?

In fact, this is also impossible, because the strength of steel is limited, it is impossible to make the ship infinitely long, human beings so far, have not made more than 450 meters of giant ships, because more than 400 meters, has exceeded the stress length of the steel structure itself.

Needless to say, such a long ship will lose its use value because of too much deformation stress even if it encounters a broken keel in a triangular wave, even if it is not a big wind and wave;

Therefore, under the premise that the aircraft carrier must have a high speed, the relationship between tonnage, ship type, and power capacity determines the current full displacement of more than 100,000 tons, which is the ultimate tonnage of the aircraft carrier.

According to the current conditions of Fengtian, it is still inland, not near the sea, and there is no port, is it necessary to buy aircraft carriers?

Yes, now having an aircraft carrier is just a pile of scrap metal for Fengtian, and it is useless.

However, Fengtian will not be limited to the current conditions, but must look at the problem from the perspective of development.

If one day, Fengtian has a coastline and a port, and begins to plan the construction of aircraft carriers, I am afraid it will be too late.

To build an aircraft carrier, you need a large shipyard.

Well, Fengtian already has a shipyard, albeit still in Germany.

Oh, it's the dowry given to Fengtian by the Junker family.

Even if Fengtian moves the shipyards that are still in Europe to his own territory, there will be a process of building aircraft carriers.

First of all, you need to master this technology.

Coupled with the time of construction, it may take five or six years for the first aircraft carrier to be launched, and by then, the Second World War is over, and the aircraft carrier will become an ornament.

Plan ahead, for Fengtian, this is the most important thing.

If a person is not forward-looking and not good at thinking strategically, then he is not a qualified leader.

Therefore, Feng Tian immediately decided to buy the two aircraft carriers under construction.

Why was the construction of aircraft carriers stopped?

Isn't it just a lack of money, Lao Tzu is not short of money, and additional funds will be added to complete the construction of these two aircraft carriers, and two years later, Fengtian will have his own aircraft carrier. (To be continued.) )
