Valley Emperor

Due to the low communication capabilities of this era, orders could only be delivered by messengers riding horses, so even if Li Xuan ordered the second stage of the operation, it would not be able to fight for a while.

Even now, the exact time has not been set!

Because the troops that launched the campaign are too far apart, the 2nd Infantry Division, which is currently preparing to attack Jingzhou, is still garrisoned in Yuezhou, and the 3rd Mixed Regiment, which is preparing to attack Anlu Prefecture, is still in Wuchang. The government is waiting.

The 1st Infantry Division of the 1st Army, which went to the west side of Hanyang for the landing operation, has just retreated from Huangzhou and is still floating on the boat. Together, they are still in Wuchang.

The other main unit, the 7th Mixed Regiment, is still in Shizhou. This unit still doesn't know that it has been assigned to attack Badong and defend the mission of Sichuan troops to rescue Jingzhou.

Limited by the low means of communication, even the Datang Army had already established a complete post station system on the front line of the Yangtze River, and military orders could be delivered in an expedited manner of five hundred miles.

However, the orders issued by Li Xuan in Jiujiang also took many days to reach the troops, and then the troops would carry out relevant actions according to the orders.

This is also the reason why the second-stage combat plan formulated by the Privy Council has a length of more than three months!

And the normal southwest battle will be a battle that lasts half a year or even longer!

Of course, the time for the main force confrontation between the two sides actually takes far less time, and most of the time is wasted on passing orders and troop marching.

If everyone is in the same place, and then the decisive battle is directly fought, plus the preparation time is only a few days, the real short-armed battle time is estimated to be only a few hours.

However, for these few hours, the Datang Army needs to spend several months to prepare.

At this time, Li Xuan desperately hoped that the radio could be developed sooner, not for anything else, but to be able to quickly transmit various military orders.

It is a pity that although there are many evildoers in the Royal Institute of Technology, it is not so easy to develop radio communication. This thing is better than steam engines, rear-mounted artillery, rear-mounted rifles and other weapons. more difficult.

Li Xuan set up an electrical research group at the Royal Institute of Technology for a long time, but he is still stuck in the exploration of various electrical theories and repeated experiments in order to gain a deeper understanding of electrical knowledge, otherwise, They just know the rankings of electricity and electromagnetism are useless!

What's more, even if you know electromagnetism, you also know what is called wireless telegraphy, but how do you make it?

Not to mention the others, how to provide a stable power supply for the telegraph is a super problem for them, directly using the power engine, but how to stabilize the voltage?

For chemical batteries, what materials and combinations are used?

These, in fact, are the problems they urgently need to solve.

So now, they actually know a lot of theories, but the theories they know are all memorized by rote, but how to apply what they have learned and how to use these theories to get out the telegraph, that is the problem.

This is like everyone now knows that nuclear fusion can be used as super energy, but no one can do it, because it is very difficult to turn nuclear fusion into controllable nuclear fusion.

In fact, many scientific and technological researches in the Tang Dynasty have these problems. They have learned a lot of high-level things from the simple textbooks written by Li Xuan himself.

For example, the students of the Royal Institute of Technology who study steam engines, they know what a high-pressure steam engine is, and also know that a high-pressure steam engine can obtain greater power with a smaller volume and weight, but can it be done?

Can't do it now!

There is nothing else, that is, the material is not good, the processing technology is not good, and in the final analysis, the processing technology is not good, that is also because the material is not good.

Li Xuan can tell them all kinds of messy common theories, but Li Xuan can't tell him the proportions and formulas of various materials. He is not a science student. It's good to know some basic theories. Is it possible that you can still Count on him to know the ratio formula for titanium alloys is not...

They made a lot of tests, and the final test showed that with the current material and processing level, the pressure of the steam engine is greater than 0.13 MPa, so it is unbearable.

And this is actually the level in the laboratory. If it is industrial production, this data needs to be further reduced to 0.1 MPa.

Otherwise, they would have built the high-pressure steam engine long ago, but it’s not that they couldn’t design it. There are a lot of design drafts. If the materials and processing levels pass the test, they can be built in minutes. If they can be built, then they will be built new. The five-horsepower steam engine is only one-twentieth the volume of the existing low-pressure steam engine.

What is this concept?

This means that, if they are really developed, these high-pressure steam engines can truly be used as the power for trains and warships, instead of the current situation, which can only be used as toys.

However, the high-pressure steam engine is limited by materials and processing technology, so it cannot be developed. Therefore, the steam engine research group at the Royal Institute of Technology has basically given up the research on high-pressure steam engines. Well, it is to improve the existing low-pressure steam engine wholeheartedly.

Although the low-pressure steam engine is large in size and low in power, it does not matter, it is not used as industrial power!

Nowadays, several enterprises of the Ministry of State-owned Enterprises have begun to use steam engines in small quantities, especially in several coal mining areas, basically using steam engines to pump water.

The Jiangnan Textile Company also began to use a small amount of steam engines.

As for the private enterprises, I'm sorry, they don't have any use. It's not because of confidentiality that they won't sell to them, but because they don't want them!

The steam engine developed by the Royal Institute of Technology this year and produced by Zhaoqing Machinery Company sounds like a very high-end thing, but the cost of use is basically more than ten times that of water power.

Large coal consumption and high coal prices lead to high fuel costs.

What's even more desperate is that the failure rate of this ghost is still very, very, very high!

It is a state-owned enterprise under the Ministry of State-owned Enterprises. It has a lot of money, and it has a political mission. It is necessary to support the development of steam engines. This steam engine cannot be sold, and no one is using it. How to get more research funds? How to improve it Steam engine!

So even if it's trash, they have to grit their teeth and use it.

But people are not stupid. After using a steam engine, they know the broad prospects of this thing. It doesn't matter if it is not used now, it can be used in the future, so they buy the current steam engine to support the research and development of the steam engine, which is also conditional Yes, that is, they signed a contract for exclusive rights, and when the new steam engine is developed, they have the condition of two years in advance to purchase and use it, and the term is ten years.

That is to say, within ten years, the Royal Institute of Technology will come up with a more practical steam engine. After it is developed, the Ministry of State-owned Enterprises will have the right to use it exclusively for two years. After two years, this type of steam engine can be sold to the outside world.

If it wasn't to seize the opportunity in the future, why would they spend so much money every year to buy and use these steam engines that could lose money to their grandma's house?

However, the research and development funds of steam engines are not only supported by the subordinate enterprises of the Ministry of State-owned Enterprises. In fact, the navy is the main support!

However, the navy does not want low-pressure steam engines, and has no interest at all in such huge steam engines that are destined to be used only in industry. They are only interested in high-pressure steam engines, and they are very interested.

Although they haven't seen even one real thing, just looking at the data on paper is enough to make them very excited. If they really want to figure it out, they will directly put it on the battleship in minutes, and then use it as the power of the battleship.

The materials are not good, the processing workers are not good, and this high-pressure steam engine can't be built?

The navy said it doesn't matter, the materials are not good, let's start with the materials, and the processing technology is not good, let's start with the machinery and equipment needed for processing!

What, you said that material research and development requires countless tests, which requires a huge amount of money. Just doing the test will cost tens of thousands of taels for a year. The navy said that although our navy's military expenditure is not as much as the army, it still has a lot of money every year. A few million taels, it's not a big deal to spend 10,000 taels this year, we have covered all your material research and development.

Then the students of the Royal Institute of Technology look contemptuous. This is just one of the research and development funds for materials~www.wuxiaspot.com~ We have at least dozens of similar material research and development projects at the Royal Institute of Technology. If your navy wants us in a short time Once you get it out, you need to launch a lot of projects at the same time, and you can’t stop it without a few hundred thousand taels a year!

The navy said, money is a piece of shit... Wait, what are you talking about, hundreds of thousands of taels?

Hemp egg, why don't you go grab it!

No, I will go to the army. The research and development of this material is not the business of our navy family. They also use all kinds of new materials in the army to make guns. They have money in the army, so go to them!

However, the navy could not afford to support the research and development of all materials, but it still supported several of the projects that seemed to be more reliable, and then after reckoning, the generals of the navy found that the shadow of the high-pressure steam engine was not seen. They have already spent almost 100,000 taels of R&D funds for this.

This will allow them to equip a cruiser.

This reckoning made their teeth hurt, but no matter how painful their teeth were, they had to grit their teeth and continue to give money! .
