Headache, originally he wanted to wait, with the trigger fuse, to make a real rear-loading artillery, even if it is a smoothbore gun, it is much stronger than the front-loading seat retreat, it really doesn't work, it's good to retreat the gun.

What does it mean to retreat the cannon, that is, there is no device to reduce recoil, and after one shot, the entire artillery jumps backwards.

In order to solve this problem, the initial use of the orbital seat retreat, that is, the gun is installed on two tracks, after the gun is fired, when it retreats, it is to retreat along the track, if there is a spring, it is better, can greatly reduce the recoil.

The next time the cannon is fired, follow the track and push the gun to the firing position, this method is more suitable for the battleship, and the land battle will not be, the gun itself is very heavy, plus the weight of the track, transportation becomes a big problem.

The tube withdrawal gun relies on the retractable double-layer barrel to effectively reduce the recoil after firing, and this device, after the invention of artillery, has been used for hundreds of years, until the gunpowder weapon is completely withdrawn, and this method is used.

It sounds simple, but it is not easy to manufacture, poor work, machining accuracy, lubrication, spring shock absorption, there are too many small devices needed, and Renault can't handle it.

Counting on those officials of the Ministry of Industry, forget it, Xiao Man is a shipbuilding master, but if you look at the ships he built before, you will know that they will always be played within the framework of wooden sailboats, at most they will be stronger and faster, so it is useful.

Seeing the ironclad ship, Xiaoman doesn't want to build a sailboat in his life, this trick is too bullying, even if there is no weapon on the ironclad ship, it can sink the wooden ship, you still play a fart.

Renault's standard state of the secret master long exam made Lan Bing dizzy, why did this person talk and talk about it, and start to stay by himself?

Fortunately, this time it was not long, if there were enough manpower, it was not impossible to build a batch of front-loading artillery first, anyway, the technology and materials were ready-made, as long as the thing was cast and turned around in the chamber with a lathe, it could be used, and it would not cost much.

Now that the craftsman battalion of the Shengong Temple is working hard in the laboratory, the skill tree has climbed very fast, and with the steam engine, it no longer relies on water power, and the steam machine tool is not far away.

With a large number of manufactured copper wires, as well as the magnets transported, the motor experimental team has more than a dozen generators, although the power is still small, but after all, there has been great progress, Renault has found the location of the underground river, began to build a dam, ready to build the first hydroelectric power station in Dachu in one to two years.

Renault knew that it was useless to be in a hurry, the hydropower station was easy to build, but there were no electrical appliances, there was electricity and fart, and when the generator experimental group was formed, there were two other groups studying electric motors.

If this can be done, there will be electric machine tools, and that is the time for the great development of machinery, and it is too early to think about this.

"Alright, let's get on board. Renault shook his head slightly, let's take a look, I don't know if the battle in Chunjiang Mansion has started at this time, the satellite signal here is too poor, a large number of microorganisms are consumed every time, and it can only be seen when Renault is very focused, so it is impossible for Renault to stare at it all the time, and can only watch it every few days.

Experiment No. 2 of the same size, there were a lot of people on board, Lan Bing took thirty-six uncles on board, most of them returned with minor injuries. Mozi brought thirty experimenters, who were responsible for guiding the maintenance of the power system.

Xiao Man boarded the ship with fifty craftsmen, and he was responsible for testing the overall effect of Experiment 2.

In addition to these personnel, there are also a hundred members of the Shengong Temple Guard, who will become the first batch of naval officers trained by Renault.

It was not the first time that Lan Bing had boarded Experiment No. 2, and every time she came up, she felt different, sitting on a high command chair and looking at the transparent glass portholes, giving her a completely different experience, it turned out that driving a battleship could be so comfortable.

Take the microphone on the bulkhead, pull the pointer to all the staff to talk, press the send button, and say: "This is the control tower, and all units report the situation." ”

It's fresh, you can actually press the send, you don't need to shout loudly, the whole battleship is up and down, no matter where you are, you can hear your own voice and orders, which is so convenient.

The backwardness of the wooden battleship is all-round, just the transmission of orders, it is a big problem, it is good to say in normal times, as long as three heralds are enough, but to start a naval battle, although he has only experienced such a short naval battle, Lan Bing feels that the heralds are far from enough, even if she has ten heralds, it is not enough.

Especially when the Austrian battleship fires that kind of dense iron ball, the herald sent out must run around the battleship in the face of the rain of bullets, and none of the three people who go out will come back alive.

"The third inspection of the fuel tank is complete, the fuel is in place, and the report is complete. ”

"The Tibetan cabin is ready, all eighty sailors are in position, and the report is complete. ”

"The inspection of the material cabin has been completed, all the materials have been reinforced in place, and the report has been completed. ”

"The deck is ready, the report is complete. ”

"The power compartment personnel are in place, and the report is complete. ”

One by one, voices came from the loudspeaker in order, Renault's wired telephone could not be popularized in Los Angeles, after all, the distance was not easy to use, but the second experiment was only sixty meters long, even if it was a thousand meters long, after several improved telephones, it could be used.

The wired phone is placed on the battleship, and it is so easy to use. Considering that it would be damaged in naval battles, Experiment 2 had three wired telephone lines and one wireless communication line.

After all, it's an experiment, Mozi will be able to install all the things that can be installed, the current wireless communication, or a lot of problems, the distance is naturally no problem, but the break is too fast, a professional maintenance person, busy from morning to night, can not guarantee that the wireless call can operate normally.

"The power compartment is ignited and pressurized. ”

"The command was received, and the power compartment was ignited and pressurized. ”

Lan Bing put down the microphone, picked up the captain's command manual, and looked at it again, this captain's manual with tens of thousands of words, she listened to it no less than fifty times, and she could memorize it from beginning to end, although it couldn't be done word for word, the general meaning would not be wrong.

Don't look at her constantly flipping, in fact, Lan Bing doesn't recognize many words, just over a hundred, and when she used to read manuals, she needed a bachelor to guide her.

For some reason, as long as this booklet was in his hand, Lan Bing felt more at ease. It is said that most of these manuals were dictated by Lei Shi.

When Lan Bing saw the Experimental No. 2 Ironclad Ship, she understood why Lei Shi had such a high reputation in the Divine Crafts Palace, and even she, a girl who grew up on the sea, was suppressed, Ironclad, who had played before?

After Lan Bing gave the order for ignition and pressurization, it took a full three quarters of an hour before the report of the power compartment came: "The power cabin reports to the control tower, the primary pressurization is completed, the reading is 3.2, and the report is complete." ”

Without even thinking about it, Lan Bing knew that he could set sail, and according to the captain's manual, when the pressure reached more than 3.0, Experiment 2 had the lowest power coefficient to move.

The maximum power design coefficient of Experiment 2 is 8.0, which can theoretically propel a fully loaded ironclad ship to reach a maximum speed of 21 knots in a windless state.

The first time I heard the bachelor talk about the maximum speed of Experiment 2, the sailors of the Charge were amused, isn't this, the fastest speed oars of the Southern Navy can only be sixteen knots Okay, that's going to tire people to death, you still want to run twenty-one knots of the boat made of fine iron?

In fact, the maximum speed of Experiment 2 was not 21 knots, but 29 knots. Naturally, the manual does not write like this, and in order to achieve a high speed of 29 knots, it is necessary to have three boilers at the same time to output power at maximum pressure.

At the beginning of the design, two boilers worked and one was maintained, so the maximum was only twenty-one sections. Because it is an experimental iron ship, using the largest type of boiler at present, Experiment No. 2 is a typical horse-drawn trolley, and the maximum speed mark has been quite conservative.

But this speed, in the eyes of Lan Bing's water army, is another matter, do you understand what twenty knots mean?

You can run 160 miles in an hour, you know, you can run nearly 2,000 miles in one day and one night, this is a battleship, do you think it's a dragon foal or a black hair?

"The power is coming out slowly. Lan Bing said, don't care about those manuals, it's a mule or a horse, just pull it out and slip it on.

"Turn the rudder five degrees to the left. Putting down the microphone, Lan Bing turned his head and said to Yu Erbo, who was at the helm, Yu Erbo was originally the helmsman of the Charge, and on a battleship, the best protection was the captain, and the second was the helmsman.

The captain is the soul of the battleship, and the helmsman is the direction of the battleship. So in that naval battle, among the ten people who survived without injury, including Yu Erbo.

Like Lan Bing, she needs to memorize the captain's manual, and Yu Er also needs to memorize the helmsman's manual, that kind of play, it's really life-threatening, it's not okay if you don't memorize it, there are two strong guards with sticks standing on the side, and you will be beaten if you make a mistake in reciting a word. I have to say that the results of teaching with sticks are still very remarkable.

According to the theory summarized by Huya, there are no stupid people in the world, and the difference lies in the severity of the beating. This bastard seems to have forgotten that he has been with his husband for several years, and he has to stumble and make mistakes when reading a book.

Experiment 2 found the grinding and moaning sound of fine iron, and the sound of metal came from it, which made people's hearts beat. With the sound of metal, Experiment 2 moved slightly, then again......

With the huge propeller, under the action of steam pressure, slowly rotating, the helmsman changed direction, several sailors on the foredeck twisted the winch, put away the heavy iron anchor, and the bow of the experimental No. 2 fine-tuned and moved forward.

"Power cabin, report pressure. ”

"The power compartment reported that the pressure increased to four point one. ”

"Increase the momentum. ”

"The power compartment received. ”

With one command after another, under the command of Lan Bing, Experiment No. 2 slowly sailed out of the dock and headed towards the sea, and in the sky above Shitong No. 2, ten manpower planes and two airships followed closely.

Ironclad ship, set sail!
