The all-steel test ship used 4 boilers and 2 steam engines, and was very bold in eliminating the sail as a power plant. Pen % fun % Pavilion www.biquge.info

However, although the sail was removed, the mast was retained, and the addition of a ranging device and a lifting platform connected to the steam engine could lift about 300 pounds of things to the watchtower at the top of the mast in one minute.

In addition to arranging sailors to go up to watch and guard, the watchtower on the ship also has a very important combat capability that is still in the stage of secrecy and cannot be made public.

Although Chen Xin is very concerned about this ability, he does not want everyone to know about it, so he has skipped this article for the time being and has not asked the navy to demonstrate it.

In order to cooperate with the power of the steam engine, the test ship specially designed a coal storage bunker, and the maximum designed coal load reached about 600 tons.

Moreover, there is no way for the steam engine to start with coal alone, and the steam engine, the steam engine, its power source, is still the water vapor produced after heating water.

Therefore, the all-steel test ship also needs to have enough water to provide steam power.

The most important thing here is that seawater cannot be used as boiler water, and the water used in the boiler must be freshwater.

Therefore, this all-steel test ship is specially designed with several freshwater tanks, and the design drawings show that the whole ship can store about 300 tons of fresh water.

The whole boat is streamlined, with a flying shear shape at the bow and a square stern.

The increase in speed brought about by this type of ship, coupled with the steam power plant, is also very obvious, so that the design speed of this all-steel test ship has reached an astonishing 18 knots.

In this era when the speed of global sea ships is still hovering between 3 and 8 knots, the significance of the speed of 18 knots is simply extraordinary.

This all-steel test ship was built in the name of a warship, so naturally it could not be without armament.

Originally, according to the custom of shipbuilding, after the hull was built, it was first launched to try the structure of the hull, and then outfitted and installed various equipment such as artillery and observation.

However, the naval shipyard carried out detailed demonstration work before the construction of this all-steel test ship.

A set of miniature full-scale models was established, and the tank trial experiment was carried out.

Some of the basic characteristics of the vessel have been determined.

Moreover, although this all-steel test ship is said to be a "giant ship", it is only a "giant ship" in the past few decades.

At the level of 3,000 tons, even the peak displacement of the era of sail battleships, first-class battleships, and wooden warships that appeared in the next few decades did not exceed.

This test ship does not have too sophisticated instruments, and it cannot be violently shaken, so there is no need to wait until it is launched to carry out outfitting so troublesomely.

In addition, the current kingdom has signed trade agreements with Spain and the Netherlands, and will soon welcome a large number of foreign merchant ships in Pyongan County.

The kingdom needs to strengthen its maritime strength as soon as possible, in case these scum who have crossed the sea, after seeing the prosperous large-scale industrial production, come up with any bad thoughts.

It is necessary to allow this battleship to become combat ready as soon as possible.

Therefore, when it was on the slipway, the Navy Shipyard installed some guns on the all-steel test ship in advance.

According to the original plan, this all-steel test ship can be equipped with more than 3 150mm guns, 10 105mm guns, 10 40mm guns, and some other related rapid-fire or large-caliber weapons.

However, now the 150mm gun has not been thoroughly developed, so it is impossible to equip the test ship.

The 105mm gun, which is still being improved, has not been completely finalized, so it can only be produced on a small-scale experiment, which cannot meet such a "large" quantitative requirement.

Small-caliber rapid-fire weapons cannot be finalized because of the issue of primer production and caliber, and at least until a decision is made at the weapons symposium held in three days.

Therefore, the current all-steel test ship is only equipped with 2 105mm guns, and 4 88mm guns, plus 8 40mm guns.

Anyway, it is a test ship, and in the future, this warship will be constantly modified to meet the experimental tasks of the Navy and various factories, and by the way, complete some naval combat missions.

In Chen Xin's heart, the launch of such a cutting-edge warship is of great significance, and it directly announces the end of an era.

Just like after the "Dreadnought-class" was launched in history before the crossing, all the warships in the world were suddenly in a position of being eliminated.

After all, in this era, the caliber of front-loading smoothbore artillery has not yet reached the 19th century, which was as perverted as firing more than 100 catties of shells.

In this era, it is impossible for the mainstream smoothbore guns to penetrate the hull structure of an all-steel test ship.

At the speed of about 3-8 knots of sailing ships in this era, it is impossible to match the all-steel test ship with a design speed of 18 knots.

Fight and fight, run and run, in front of the kingdom's cutting-edge warships, all the warships in this world are outdated.

However, the all-steel test ship also has its own flaws, that is, the utilization rate of weight is really very low.

The whole ship is fastened with a rivet structure.

These rivets that hold the hull structure, one by two, look inconspicuous.

But after the whole ship was connected with rivets, a problem was found in a calculation.

In the unloaded state, twenty percent of the weight is taken up by these inconspicuous rivets.

"Lao Bai, record it, the next stage of technical public relations on the navy, focusing on welding technology, this is a powerful black technology that can reduce the weight of ships by 20%, and it is also a big savior of the damage management industry, a powerful weapon that can be rescued from sunken ships, and it must be developed in a key way."

"Yes, master."

Glancing at the Admiralty who were still in a state of excitement, Chen Xin turned around and led Anya and the guards to another slipway.

Several executives of the Admiralty have long known that Chen Xin's main purpose today is not an all-steel test ship, no, it should be said, not entirely for an all-steel test ship.

Compared with the 3,000-ton warship, what Chen Xin hopes to see today is another new type of ship that is not a combat ship.

Everyone in the Admiralty hurriedly greeted each other and followed.

Chen Xin did not choose to take a car, but scattered, led by several naval officers, walking slowly, chatting as he walked, to learn about the recent situation of the navy.

"What is the situation of those three wooden sail warships, especially those two meritorious battleships?"

Chen Xin is talking about the two meritorious battleships that were heavily damaged after the naval battle with the Dutch half a year ago.

"After repairing the original damage, the Glory and the Tenacious have made up for the losses of the capable personnel on board to replenish the personnel, and after half a year of running-in, they have recovered their combat effectiveness and can perform combat missions."

"That's good, next, the Spaniards and the Dutch will come to do business with us, those guys, they are all scum, we have to be ready to fight at any time."

"Yes, the navy will live up to your expectations."
