Of course, it was impossible for the attendants to let Dong Shuheng go into the water on this thing.
This is a test product. Even after the technology matures, submarine warfare will also be a high-risk industry.
"Keep up your efforts and strive to build a larger, more stable submarine that can be put into actual combat." Dong Shuheng encouraged Deng Bolin.
"Well, President, we will definitely work hard. All the experimental parameters of the No. 0 boat will be collected soon. It won't take long before we will produce a 500-ton real combat submarine." Deng Bolin.
Guarantee said that with the experimental data of the No. 0 boat, he was confident in building a usable submarine.
"By the way, President, I wonder how the development of the new battery in the Electric Power Laboratory is going?" Deng Bolin took advantage of this opportunity and asked insinuatingly.
There is no affiliation between the various laboratories; they are all governed by their own lines.
The only one who can give direct orders to various laboratories is Dong Shuheng.
Each of these key laboratories is very good, and most of the leaders are academicians of the Academy of Sciences.
Even the senior officials in the cabinet were not dissatisfied. But most of them were convinced of Dong Shuheng.
It's not because Dong Shuheng has great power, but because he can always make good suggestions to those laboratories.
As he said himself, he knows a little bit about everything but is not good at anything.
The main limitation on the development of submarines now is the lack of reliable, durable and large-capacity batteries.
Even Dong Shuheng, a liberal arts student, knows that a submarine can rely on a diesel engine to drive a propeller when sailing on the water surface, and at the same time charge the battery on the boat.
But during combat, the submarine has to dive underwater and travel underwater. At this time, the submarine is isolated from the outside world and has no source of oxygen.
At this time, even the crew's breathing oxygen must be regenerated or through the reserves on the boat.
The diesel engine will definitely not be able to run unless a gas pipeline is extended to the sea. At this time, the electricity in the battery on the boat will be used to drive the electric motor to drive the propeller.
Therefore, there are usually a lot of batteries installed at the bottom of the submarine. These batteries not only provide power, but also act as ballast stones.
Without anti-submarine equipment, submarines are almost invincible as underwater hunting masters.
Dong Shuheng has always had a premonition that there will be a great sea battle between the East and the West.
Now that we have entered the era of ironclads, there is nothing to take advantage of.
What matters is the tonnage, the thickness of the armor, and the caliber of the artillery.
Fighting these things, the Renaissance Army is no match for Europe, or even a match for the Great Empire, which has an area of 20 to 30 million square kilometers and the sun never sets.
Because the other party has more resources.
So what should we do? He has to find some tricks, or he will have to waste China's energy to engage in an arms race with others.
It is impossible to engage in an arms race, not even in this lifetime. This is simply an insult to the intelligence of the time travellers.
Through the Jianghe-class frigates, the Renaissance Army successfully defeated Spain, which was once an old colonial empire and is now Europe's third-rate power.
This dirty trick has been made public, so it will no longer have miraculous effects.
Dong Shuheng must have new back-ups and new tricks.
This was how the submarine was born.
Dong Shuheng has already known about the problem Deng Bolin mentioned. There are indeed certain problems with the original battery used to drive submarines.
The battery has been invented a long time ago and has been used in experiments and telegraph fields.
However, this kind of silver-zinc battery is not only expensive to manufacture, but its power supply capacity is also seriously insufficient.
Dong Shuheng's purpose is to at least enable the submarine to submerge to more than 100 kilometers.
This is considering that some strait areas controlled by future enemies will require continuous submersible navigation to pass.
Therefore, Dong Shuheng had already instructed the electric power laboratory led by Xu Shou to start developing a new type of battery.
It is actually not difficult to conduct battery experiments. The key lies in finding the right metal to make the battery.
In the end, Xu Shou chose lead. The cost of this metal is relatively low, the power supply capacity is relatively good, and the charging speed is also fast. This leads to lead-acid batteries.
"Lao Deng, I came here this time to tell you the good news. Our new battery has come out. After the things are shipped, you can try it and see how the parameters are. Anyway, Lao Xu is patting his chest and following
I promise it will work this time."
Not only Xu Shou, but also Dong Shuheng himself spent a lot of effort on this battery technology.
The current battery technology is mainly in the hands of the British.
When Xu Shou was studying in Europe, he was not able to obtain cutting-edge technology in this field.
When the Renaissance Army introduced telegraph machines, the batteries that came in at the same time were also several generations behind the technology.
After Xu Shou returned to China, he took storage batteries as one of his main research subjects. Because the development of electric power is inseparable from batteries, which are power storage devices.
Of course Dong Shuheng also gave him a lot of advice.
In addition, the European action team also took several actions to deal with the battery issue, even losing three or four peripheral intelligence personnel.
Finally, lead-acid battery related technology was obtained from the British, which inspired Xu Shou's experiments.
"Of course, as long as the batteries can be put in place, our practical submarine will definitely be built in advance." Deng Bolin was extremely excited after hearing Dong Shuheng's words.
People who engage in scientific research are like this, they put all their joy, anger, sorrow and joy on their faces, they are just straight men.
"Okay, I'll be waiting for your good news."
Dong Shuheng not only watched the development of submarines.
We also visited the torpedo boat production area of Wuchang Shipyard.
Torpedo boats must form a swarm to be effective.
Therefore, in addition to production in Lushun, there are manufacturing production lines at Wuchang Shipyard and Gaoyou Shipyard.
It is definitely not possible to build ironclad ships on a large scale. Dong Shuheng does not have that kind of economic strength now.
The Seawolf-class catamaran torpedo speedboat is Dong Shuheng’s trump card that he is currently preparing to deploy in offshore waters.
In such a vast sea area, it is impossible to place an armored fleet in every place. So when the enemy attacks, the port should have the ability to take the initiative in addition to the forts.
According to Dong Shuheng's current plan, the Renaissance Army can only support three armored fleets.
One branch was placed in the Nanyang Sea, which was intertwined with the colonies of Western colonists.
This armored fleet must cooperate with the maritime power of the vassal states and safeguard the maritime interests of each vassal state and the Renaissance Army here.
The second branch will be placed in the home area as a mobile force and also as the last line of defense within the first defense island chain.
The third one is the ocean-going fleet that Dong Shuheng plans to build, which will mainly maneuver in the South Pacific and the Eastern Pacific.
Then in some unimportant places, Dong Shuheng will arrange some old-fashioned naval forces. These naval forces are mainly old-fashioned warships and are mainly responsible for cruising tasks.
Even so, the fleet cannot take care of the Renaissance Army's huge maritime territory.
The original offshore patrol boats of 500 to 600 tons were unable to compete with large warships. They would just deliver food to the enemy if they got close to them.
Therefore, Dong Shuheng needs a small boat that can perform cruising tasks in normal times and has the ability to challenge large warships in emergencies.
Hence the current Seawolf-class catamaran torpedo boat.
The reason for choosing a catamaran structure is, on the one hand, to hide the chimney of the diesel engine downwards, making this torpedo boat less likely to be discovered.
On the other hand, it is to make up for the problem of insufficient tonnage and weak stability.
Catamaran torpedo boats using diesel engines can obtain greater power than steam engines, and the space occupied by the turbines is also greatly reduced.
Its operation is simple, and each torpedo boat only requires about thirty officers and soldiers to operate it.
Such costs are not low. Putting a dozen of these torpedo boats in each port king to form a brigade can pose a considerable threat to the enemy's fleet.
At the very least, you can use wolf pack tactics to harass the enemy's fleet, hold them back, and buy time for the port's defenses and the main fleet to come to the rescue.
There are more than a dozen Seawolf-class torpedo boats under construction in the dry dock of Wuchang Shipyard on the riverside.
There are now more than fifty Hailang-class ships delivered to various maritime security areas.
The construction period of this kind of ship is very short. It can be easily built after all technical problems have been overcome.
Inspecting the economic development along the Yangtze River is also the purpose of Dong Shuheng's trip.
The middle and upper reaches of the Yangtze River only entered the governance system of the Renaissance Army later. The development here is still lagging behind. Northern Hubei is better.
When Zuo Jigao was here, he had trade relations with the Renaissance Army, and the quality of the Daye iron ore here was quite good.
Through trade with the Huai Navy, Zuo Jigao managed to raise tens of thousands of troops.
It should be said that the foundation of Northern Hubei, which is the thoroughfare for nine provinces, is still good.
The business atmosphere here is quite strong.
After the Renaissance Army took over, the economy here developed rapidly because the society quickly stabilized.
When Dong Shuheng took a boat and passed the dock area of Wuchang City, he found that the area along the river was full of bustling shops and warehouses.
There are many workers on the dock helping cargo ships load and unload cargo.
It is already May, and the places along the river are already very hot.
Most dock workers work shirtless.
Some dockworkers carrying sacks would put a linen shoulder pad on their shoulders, with a hat on top to protect their heads.
Some people will sew a layer of cotton under the shoulder pads to prevent the skin on the shoulders from being worn by the sack.
They have strong bodies, dark skin, and pieces of tendon meat exposed on their bare upper bodies. It seems that although they work hard, they eat well.
When many people saw the Yangtze River Navy's gunboat passing by, they couldn't help but stop and watch, and then continued to do their own things.
Gunboats of the Yangtze River Navy normally patrol the river to ensure the safety of the waterway. However, they are not often seen because the Yangtze River is so long.
During the Manchu and Qing Dynasties, there were many river bandits in the middle and upper reaches of the Yangtze River who specialized in robbing merchant ships passing by on the river.
They usually run boats, but when they see a lone merchant ship, they will become evil and turn into bandits.
This kind of water bandits is very difficult to catch. After the revival, these water bandits still exist.
Especially now that the shipping on the river is even busier.
Some people are still thinking about doing this kind of one-time deal.
The Renaissance Army had to divide different water police areas along the river.
The situation was curbed by allocating speedboats for patrols to the marine police.
Of course, inspection and deterrence by the Yangtze River Navy is also essential.
Among the current inland river naval divisions, the Yangtze River Navy is the largest, and the Yangtze River Navy is not the original Yangtze River Navy. Several slightly larger gunboats have been added to the fleet, making it appear more powerful and majestic.
There were too many people on the pier and it was a bit chaotic, otherwise Dong Shuheng would have wanted to go to the pier in Wuchang for a walk.
To the north of the river is Hanyang Prefecture, which seems less prosperous than Wuchang Prefecture.
But a large-scale steel plant is being built there, and this steel plant mainly radiates to the middle and upper reaches of the Yangtze River.
It also provides steel for Wuchang Prefecture's shipbuilding, machinery and other industrial development.
Originally, Dong Shuheng opened a steel plant in Jiangning and was not planning to open another steel plant in Wuhan.
Because he felt that it was connected to the Yangtze River waterway, transportation should not be a problem.
However, Dong Shuheng still underestimated the huge demand for steel in the process of industrialization.
Now, even if the Renaissance Army has built five steel bases, it still cannot meet its demand for steel.
Steel is also imported from overseas every year.
Dong Shuheng estimates that this situation will continue for a long time.
Because just railway lines consume a huge amount of steel.
The Renaissance Army has a large amount of territory that needs to be connected by railways.
There are also hydropower projects planned by Dong Shuheng, which also require a large amount of steel.
This does not take into account the increase in private demand.
When people's lives improve in the future, they will definitely need steel if they want to build better houses.
Steel is needed to build more local factories.
Building tractors and cars requires a lot of steel.
In the end, Dong Shuheng decided to build another large steel plant here in Hanyang Mansion.
Perhaps because of some plot, Dong Shuheng decided to cut the ribbon for the steel plant in person.
At this time, the navy's fleet turned a bay on the river and rushed towards Hanyang Mansion across the river.
The open space along the river beside Guishan on the edge of Hanyang Fucheng has long been vacated.
A steel plant is rising from the ground, and some blast furnaces can be seen rising from the ground in the distance.
One special thing about this steel plant is that all the equipment is produced by itself.
After Krupp Jr. came over, he brought a full set of steel manufacturing technology.
This includes the manufacturing technology of steelmaking equipment. The equipment of Hanyang Iron and Steel Plant was manufactured by Dafeng's large equipment foundry.
Prior to this, they also manufactured equipment for several other steel plants.
But there is no factory that uses all its own steel-making equipment.
Of course, the entire Hanyang Iron and Steel Plant cannot only consist of steel-making equipment.
The whole factory includes 6 major factories including pig iron factory, Besse Ma Steel Factory, Siemens Steel Factory, rail factory, iron cargo factory, wrought iron factory, and 4 machinery factories, iron foundry, blacksmithing factory, fish fillet hook and nail factory, etc.
Small factory.
For this steel plant, the Investment Committee of the Ministry of Commerce invested 2.46 million yuan, holding 51%, and the local government of northern Hubei invested 1.42 million yuan, holding 30%. The remaining shares were raised from the public, and the actual
The expenditure is about 6 million Chinese yuan.
It is considered a state-owned enterprise. Many state-owned enterprises of the Renaissance Army will now use part of their funds to raise funds from the society.
Of course, these are state-owned enterprises that are not involved in core industries.
One advantage of this is that it can introduce social supervision to these enterprises.
Over the years, many employees of state-owned enterprises have become veteran employees. Over time, some people have become inert, and there has been a situation where everyone eats from the same pot and fills the gap. Some state-owned enterprises have serious bureaucracy at the middle and senior levels.
Dong Shuheng knew all these things, and he also understood that this phenomenon was almost inevitable.
In the absence of competition, human nature will gradually be exposed.
Introducing social capital through the issuance of stocks is only one aspect, and an internal competition mechanism must be established.
Competition must be established between similar enterprises, and competition must be established between the same type of positions within the enterprise.
Hanyang Steel Plant is like this. Social capital occupies a certain proportion, and several people can be elected to the board of directors of the steel plant to participate in decision-making, and they can also supervise the operation of the steel plant.
Dong Shuheng, accompanied by officials from Northern Hubei Province and the management of the steel plant, visited the entire steel plant, as if he was walking in a steel jungle.
There is an industrial smell in the air.
This place is really big. In addition to the steel factory, supporting living areas have also been built.
This place should be called Steel City.
Seen from a distance, this steel city is not much smaller than the nearby Hanyang Fucheng.
After it is put into production, tens of thousands of workers will gather here, plus their families, and a small town of nearly 100,000 people will be born.
