It was a headache. He originally wanted to wait a little longer, but with the trigger fuse, he created a real rear-mounted cannon. Even the smoothbore cannon is much better than the front-mounted cannon. If it really doesn't work, it's better to withdraw the cannon.

What does it mean to withdraw the cannon? It means that there is no device to reduce the recoil force. If you shoot a shot, the entire cannon will jump backwards far away.

In order to solve this problem, the initial use of track seat retreat means installing the cannon on two tracks. After the cannon is fired, it is backing along the track. If there is a spring, it will be better, which can greatly reduce the recoil.

Next time you fire the gun, push the gun to the launch position along the track. This method is more suitable for warships and land combat will not be possible. The gun itself is very heavy, and with the weight of the track, transportation will become a big problem.

The barrel-retardation gun was leaning against a telescopic double-layer gun barrel to effectively reduce the recoil after firing. This device was used for hundreds of years after the invention of the artillery until the gunpowder weapon was completely withdrawn. This method was used.

It sounds simple, but it is not easy to make it. It has poor workmanship, processing accuracy, lubrication, and spring shock absorption. There are too many small devices required, so Renault can't handle it.

If the Ao people have artillery, then does Da Chu have to have it? I hope those officials of the Ministry of Works will forget it. Xiaoman is a shipbuilder, but look at the ships he built before, you will know that they will always be played with the frame of wooden sailboats. At most, they will be more solid and faster, so they are useful.

Seeing the ironclad ship, Xiaoman never wants to build a sailboat in his life. Dai Chai's trick is so bullying. Even if there are no weapons on the ironclad ship, it can hit a wooden ship. What a nonsense you can do.

Renault's standard secret teacher test status made Lan Bing faint. Why did this person start to be stunned by himself as he spoke?

Fortunately, this time is not long. If there is enough manpower, it is not impossible to build a batch of pre-installed cannons first. Anyway, the technology and materials are ready-made. As long as the thing is cast and cart in the chamber with a lathe, it can be used, and it will not take much trouble.

Now, with the efforts of the laboratory, the skill trees climb very quickly. With the steam engine, the steam engine no longer relies on hydraulic power, and the steam engine tool is not far away.

With the large number of copper wires and the magnets transported, the motor experimental group has already had more than a dozen generators. Although the power is still small, it has made great progress after all. Renault has found the location of the underground river and started to build a dam, preparing to build the first hydropower station in Dachu within one to two years.

Renault knew that it was useless to be urgent. It was easy to build a hydropower station, but there were no electrical appliances. It was useless to have electricity. When forming the generator experimental set, two other groups were studying the motor.

If this matter could be done, there would be electric machine tools. That was the time for great development of machinery, and it was too early to think about this now.

"Okay, get on the ship." Renault shook his head slightly and looked at it. I don't know if the battle in Chunjiang Mansion has started at this moment. The satellite signal here is too bad. It consumes a lot of microorganisms every time. It has to be seen with Renault being very focused. Therefore, Renault cannot stare at it all the time, and can only watch it once a few days.

There were many people boarding the ship of Experiment 2 of the same size. Lan Bing took thirty-six uncles on board, most of whom were slightly injured and returned to the team. Mo Zi brought thirty experimental personnel, who were responsible for guiding the maintenance of the power system.

Xiaoman took fifty craftsmen on board, and he was responsible for inspecting the overall effect of Experiment 2.

In addition to these personnel, there are also 100 members selected by the Guard of the Temple of God, who will become the first batch of naval officers trained by Renault.

This is not the first time that Lan Bing has boarded Experiment 2. Every time she comes up, she feels different. Sitting in a high command chair and looking at the transparent glass portholes gives her a completely different experience. It turns out that driving a warship can be so comfortable.

He took the microphone on the bulkhead, pulled the pointer to the whole staff for a call, pressed the send button, and said, "This is the command tower, and each unit reports the situation."

It's fresh, you can actually click Shijian, without shouting loudly, you can hear your own voice and commands no matter where you are, which is so convenient.

The backwardness of wooden warships is all-round, and the transmission of orders alone is a big problem. It is easy to say that only three commissars are enough, but when fighting a naval battle, although she had only experienced such a short naval battle, Lan Bing felt that the commissars were far from enough, and even if she gave her ten commissars, she was not enough.

Especially when the Austrian warships fired the dense iron balls, the messenger sent out must run around the battleship in the rain of bullets. None of the three people could come back alive. None of them could be heard by clicking them.

"The third inspection of the fuel compartment has been completed, the fuel is in place, and the report has been completed."

"The Tibetan soldiers cabin is ready, all 80 sailors are in their seats, and the report is completed."

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

“The deck is ready and the report is complete.”

"The power cabin personnel are in place and the report is completed."

One by one, the sound came from the speakers in sequence. Renault's wired telephones are not popular in Luocheng. After all, the distance is not easy to use. However, Experiment No. 2 is only 60 meters long. Even if it is one thousand meters long, it can be used after several improved telephones.

It is really easy to use when putting a wired phone on a warship. Considering that it will be damaged during naval battles, there are three wired phone lines and one wireless communication line on Experiment 2.

After all, it was an experiment. Mo Zi installed everything he could. At present, wireless communication still has many problems, so the distance is naturally fine, but it was too fast. A professional maintenance worker could not guarantee that the wireless call could operate normally from morning to night.

"Power compartment ignition and boosting."

"The order was received, the power chamber ignition and boosting."

Lan Bing put down the microphone, picked up the captain's command manual, and looked through it again. She heard the captain's manual with tens of thousands of words. She could recite it from the beginning to the bottom. Although she could not make a word, the general meaning would not be wrong.

Although she kept flipping through it, Lan Bing actually didn't recognize many words, just over one hundred. In the past, when she read the manual, she needed a bachelor's degree to guide her.

For some reason, as long as this booklet is held in your hand, Lan Bing felt more at ease. It is said that most of these manuals were oral by Master Lei.

When Lan Bing saw the Iron Craft No. 2, she understood why Master Lei was so famous in the Hall of Divine Works. Even the girl who grew up on the sea was shocked. Who had played the Iron Craft before?

After Lan Bing issued the ignition and boosting order, it took three quarters of an hour before the report of the power cabin came: "The power cabin reports the command tower, the primary boosting is completed, the reading is 3:2, and the report is completed."

Without having to go through his brain, Lan Bing knew that he could set sail. According to the captain's manual, when the pressure reaches more than three points, Experiment 2 has the lowest power coefficient of movement.

The maximum power design coefficient of Experiment 2 is 8:00, which can theoretically push a fully loaded ironclad ship to reach a maximum speed of 21 knots in a windless state.

When I first heard the bachelor talk about the highest speed of Experiment 2, the sailors on the Charge were amused. Isn't this a bullshit? The fastest speed oar in the Southern Navy can only be sixteen knots, okay, that's exhausting. Do you want to run out of twenty-one knots by a ship made of fine iron?

In fact, the maximum speed of Experiment 2 is not twenty-one knots, but twenty-nine knots. Naturally, it will not be written like this in the manual. To reach a high speed of twenty-nine knots, three boilers need to output power at the same time at the maximum pressure to achieve it.

At the beginning of the design, two boilers were working and one was maintaining, so the maximum was only twenty-one. Since it was an experimental iron ship, it used the largest boiler model. Experiment No. 2 is a typical big horse-drawn cart, and the maximum speed target was already quite conservative.

But this speed is another matter in the eyes of Lan Bing and other naval troops. Do you understand what the Twenty Chapters means?

You can run 160 miles in one hour. Do you understand? You can run nearly 2,000 miles a day and a night. This is a warship. Do you think it is a dragon horse or a black hair?

"The power output slowly." Lan Bing said, not to worry about the manuals, it is a mule or a horse, just pull it out and you will know it.

"Turn the rudder for five degrees left." Putting down the sending machine, Lan Bing turned his head to the rudder, who was in charge of Yu Erbo. Yu Erbo was originally the helmsman of the Charge. On a warship, the best protected one is the captain, and the second is the helmsman.

The captain is the soul of the warship, and the helmsman is the direction of the warship. So in that naval battle, among the ten people who survived without any injuries, Yu Erbo was included.

Like Lan Bing, she needs to recite the captain's manual, and Yu Er also needs to carry the helmsman's manual. That trick is really a life-threatening thing. It's not okay to not recite it. There are two strong guards holding sticks standing next to me. If you recite a word wrong, you will be beaten. I have to say that the results of teaching with sticks are still very significant.

The theory summarized with tiger teeth is that there is no fool in the world, and the difference lies in the importance of being beaten. This bastard seems to have forgotten that he has been with his husband for several years, and he still has to stumbling to read a book, and he has read a series of typos.

Experiment No. 2 discovered the friction moan of the fine iron, and the metal sound came, which made people frightened. With the metal sound, Experiment No. 2 moved slightly, and then...

As the huge propeller rotated slowly under the influence of steam pressure, the helmsman changed direction, and several sailors on the front deck twisted the winch, put away the heavy iron anchor, and finely adjusted the bow of the Experiment No. 2 and moved forward.

"Power compartment, report pressure."

"Power cabin reports that the pressure increases to four.1."

“Increase the momentum.”

"The power compartment was received."

With one command after another, Experiment 2 slowly sailed out of the dock under Lan Bing's command and advanced into the sea. Over Shitong 2, ten manpower aircraft and two airships followed closely.

Iron armored ship set sail!
