The news made everyone in Cambridge look pale.
Especially the stone bear, in the heart suddenly had some irritability.
Others, including Adrian Carlos, may only know how much manpower and material resources it took to build the ship, but they absolutely don't know what the whole Yanhuang tribe paid behind the ship.
Only the stone bear knows how much the tribe has paid to build the ship. What the tribe pays is far from what the boat can show.
Before the first World War in the original historical time and space, there was a very reasonable saying that the strength of a country depended on the power of its battleships.
The meaning of this sentence is very obvious, but it also illustrates a problem from another aspect, that is, the level of battleships owned by a country is the embodiment of a country's comprehensive ability.
This also includes the R & D and manufacturing capacity of this country!
In fact, before World War I, even from World War I to World War II, battleships were the top weapons of a country, and they were not one of them.
Of course, in this era, you can also think of windsurfing battleships as battleships.
However, compared with the sail battleship, the technology application of Carlos is undoubtedly higher, and the two are definitely not in the same level.
In order to build the Carlos, the stone bear worked hard. He said almost everything he knew, and almost everything he could develop and manufacture.
There are many technologies that are difficult to realize in this era, such as the hot riveting technology of ship hull, the forging technology of ship steel plate, the processing technology of propeller, the high-power steam boiler technology, and the onboard telephone communication technology
No one knows better than the stone bear how much the whole tribe has done in the past eight years to build the ship.
It's like the steel plate used to build this ship. If the stone bear had just crossed, it would never have been produced. Later, when Shi Xiong became chief, he had great power in his hands, and he began to work hard to forge qualified ship steel plates.
Of course, this so-called marine steel plate is certainly far from being compared with the marine steel plate of later generations. The so-called steel plates used for ships in this era are not even better than those used for fishing boats in later generations.
But there is no way. In this era, let alone steel plates, only Yanhuang tribe can produce steel bars. In Europe, they can't even produce a roll of qualified steel bars, let alone steel plates for building ships.
But even so, Shi Xiong can't come up with any hot rolling and cold rolling technology of later generations. That kind of technology is still too difficult for the Yanhuang tribe, and the tribe does not have the ability to produce a hot rolling mill or cold rolling mill.
Therefore, the stone bear had to retreat and adopt the forging method to produce the so-called marine steel plate.
But even the forging technology, also let the stone bear headache. No other, in order to forge a qualified steel plate, you have to have at least a forging machine, right? Even the simplest forging machine can't be made now.
The steam hammer has a way to get it out, but it can't forge steel plates.
No way, stone bear can only use the most primitive hydraulic press to forge.
The working principle of hydraulic press is very simple. Shi Xiong learned it when he was in junior high school physics class. In the original historical time and space, the world's first hydraulic press will appear in England in more than 20 years. Hydraulic press is not something that is difficult to make. But even so, it took the whole tribe ten months to build a hydraulic press that could forge.
Under the constant guidance of stone bear, more than 40 talents, including Jack Williams, have been searching from Europe for this hydraulic press for ten months!
In the end, this hydraulic press is just a thousand ton hydraulic press.
This kind of hydraulic press can barely be used for forging 20 mm thick steel plate - the thickness of steel plate used for destroyer hull of later generations is only about 10 mm, but the steel of today is far from comparable with that of later generations, so Shi Xiong can only use thickened steel plate to improve the strength of the hull.
In addition, the current marine steel plate for the area of demand is not very big, are riveting technology, big deal piece by piece is
With marine steel plate, and the most important keel steel
With keel steel and ship steel plates, the ship can be built. But the problem is, you can't just use these steel to build a hull, can you? You have to have enough power to push the boat, right?
So the high-power steam boiler technology has to break through.
With the technology of high-power steam engine, you have to find a way to turn the power generated by the steam engine into thrust, right? So gearbox technology and propeller technology must be available - Shi Xiong doesn't want to use Ming wheel to push this steel warship, which is too low, and the safety is not high.
If we can't develop propeller propulsion technology, Shi Xiong would rather not build this steel warship.
So the stone bear took out the Archimedes spiral of forging propeller again
It took nearly two years for the research team to produce a barely qualified propeller!
Now that the hull, power, propulsion and weapons are available, what about internal communication?
So Shi Xiong had to instruct the scientific research team to make magnet telephone and communication wire
The outer insulation of the wire alone has kept the research team busy for decades.
When the conditions for building the ship were all met and the steel warship was built on the berth, many problems arose one by one.
Sealing of watertight cabin, sealing and drainage of deck after waves, sealing of watertight door, etc.
I don't know if I don't build it. I only know that the main problems I encountered before are just appetizers. When the ship starts to build, there will be all kinds of problems and problems. It's really out of my mind.
For example, when it comes to the later stage of construction, the sealing of propeller shaft has become a difficult problem.
Although the stone bear knows how to seal the propeller shaft, it is still impossible to make that kind of sealed bearing in this era. So a group of people pondered for a long time, then chose a compromise method, using rubber and vegetable oil lubrication to seal.
This method is not a long-term method. If the propeller shaft runs for a long time, the natural rubber used for sealing will inevitably produce huge wear, and the sealing effect will be greatly reduced.
But there is no way. Under the current situation, we can only choose this method for the time being.
All in all, the difficulties encountered before and during the construction of this ship add up to countless. Otherwise, it would take six years to build the ship.
In order to solve these problems and sufferings, and to successfully build this ship, everyone, including the stone bear, is absolutely searching their brains.
It's no exaggeration to say that the energy used by the stone bear in conquering other tribes in this continent is not as much as that used on this ship.
After paying such a high price, the ship is now successfully launched. It was originally a very happy thing, but now there is a problem of water leakage in the propeller shaft. How can the stone bear not feel anxious?
