Zhao Hao walked into the manufacturing research workshop and saw that the light wiped on the ground was visible. Large steel machinery was neatly arranged, and various tools were hung on the wall according to the slabs. Countless small parts were sorted and boxed, each stored in a vertical cabinet, with labels on the boxes. Those who didn't know thought they had entered the pharmacy shop.

It was cleared up in advance.

"Isn't this uncle not here for several years? Everyone was so excited that they couldn't sleep and kept cleaning all night." Zhao Shizhen also felt that the people below were too busy, so he hurriedly said with a embarrassed smile: "But we are not much worse than this in normal times."

"I'm not here to check hygiene." Zhao Hao's eyes fell on the steel machinery and identified one by one:

"Lathes, planers, drilling machines, grinders, milling machines...good guy, let's have another milling machine and boring machine, and you will have all the working mother machine."

"This is not what we created." Zhao Shizhen said without greed for merit: "It is all the research and development results of Institute 2003 over the years."

03 Mechanical Research Institute, the director of the Research Center is also appointed as the director of Zhang Jian…

Zhang Jian pushed the black-framed glasses and said, "I'm ashamed. The master has not done the first task well. No matter how much basic work is done, I'm shameless."

"Hey, Jingyang's words are wrong." Zhao Hao shook his head apart and said, "Why do we encounter so many difficulties in developing prime moves? It is because our foundation is too poor. We have done these basic tasks solidly and improved our manufacturing level. It is natural to overcome prime moves."

Zhang Jian’s so-called primary task was named by Zhao Hao, who was still young at that time, as the ‘Human Compensation Plan’.

Regarding this naming that ordinary people cannot understand, Zhao Hao explained that because the task of this plan is to improve the Zhang Jian-style steam engine into a prime mover that can provide power to all walks of life!

Once this universal prime mover is developed, it will revolutionize the weak and weak hands that will make humans extremely powerful, liberate the human brain to deal with all difficulties, and will send human civilization to a new height that our predecessors cannot imagine!

Zhang Jian and his fellow researchers were deeply attracted by the steam era described by Zhao Hao. They vowed to work hard to complete this "human replenishment plan"!

At that time, Institute 03 was actually quite confident. Because the Zhangjian-style steam engine was officially put into use more than ten years ago, it was only installed in various mines to pump water, so it is also called the Zhangjian-style water pump.

Because the water pumped by a censor pump is equivalent to the work done by fifty horses, and it can work day and night, and the cost is only one-sixth of the water pumped by horses and one-third of the water pumped by people. Therefore, it not only quickly became the standard configuration for major mines, but it was also installed by the canal to supply water to the reservoirs and sluices. It is also used in cities to pump water for water towers and provide drinking water for residents.

Currently, more than 500 steam engines produced, installed and maintained by the "Jiangnan Power Company" have been produced, installed and maintained, covering Jiangnan South China and overseas administrative regions. To some extent, it has even become a symbol of Jiangnan Group.

However, Zhao Hao is far from satisfied with this first-generation steam engine. Its main disadvantage is that it is very low thermal efficiency. This is because when the steam enters the cylinder, it condenses on the cylinder wall that has just been cooled by water, and a large amount of heat is lost.

In addition, this first-generation machine only utilizes the vacuum formed by the cylinders of low-pressure boilers when they are condensed, and does not use the tension of steam, and the energy loss is large. Therefore, it must be made to be extremely large and consume a lot of coal to provide perceived power.

Although in this way, there is no need to worry about the danger of boiler explosion due to excessive steam pressure. However, Zhang Jian type steam engine is not competent for the work of the prime mover.

The current compromise is to build a water tower and a pool, use the No. 1 machine to pump water and store water, and drive the water truck to provide stable power. This is the method of Tangshan's coal-steel complex to drive the hydraulic rolling mill. However, this stupid, big, black and thick approach is obviously not universal, so we still have to find a way to improve the No. 1 machine to make it smaller and more efficient until it can be widely used.

What made them more confident was that the North Star Zhao, the North Star in the dark, had pointed out the direction and told them that what you want to do is to boil water with a sealed pressure cooker, and then use a pipe to pass the steam into a piston cylinder to push the piston downward. After the piston is poured back, open the valve and discharge the steam into the condenser. This is the principle of the new generation of steam engines.

It doesn't sound difficult at all. However, Zhang Jian and his colleagues never expected that this "human make-up plan" would be so difficult every step, and there are too many problems to be solved.

For example, it took Zhang Jian's team nearly a year to tinker with the valve between the cylinder and the condensation cylinder. However, this brought about new problems. What should I do if the condenser is filled with condensation water and air, so I can't discharge it? The team spent more than half a year to design a pump to solve this problem.

In addition, the problem of the cylinder has not been solved yet. First, if the strength is insufficient, long-term high temperature and high pressure work will lead to explosions and cause major accidents. Second, the processing accuracy of the cylinder is also a big problem. If the inner wall of the cylinder is not smooth and round enough, then the sealed cooperation with the piston will have a great impact and will cause serious air leakage.

To solve these two problems, steel with higher strength must be used to cast the cylinder blank, and then the cylinder is bored with a boring machine.

The problem is that the group has no boring machine yet. So we have to stop and develop boring machines...

In addition, a precision gear set connected in series and a connecting rod-driven valve system are needed to cooperate with the work of the steam engine. This requires repeated design and high-precision processing... Those lathes, drilling machines, grinders, and planers are mostly born from this.

In short, there are countless problems, which is much more difficult than improving the steam engine in another time and space Watt.

This is normal, because at the end of the 18th century when Watt was located, Britain had established a fairly complete scientific and industrial system, metallurgy and machine manufacturing industries, which were sufficient to support Watt to turn his fantasy ideas into reality.

Although Zhao Hao has made rapid progress for more than ten years, it is still not enough to smooth out the gap of two hundred years and help Zhang Jian and the others pick this industrial flower.

So Zhang Jian and the others can only rely on themselves to increase their manufacturing level little by little.

Fortunately, this research and development process itself will drive all-round progress in its own technical level, allowing the entire research center and even the group to benefit greatly.

For example, machine tools such as the Ordnance Research Institute...

In the workshop, researchers from 00 institutes demonstrated a major advance in gun barrel manufacturing technology for Zhao Hao.

Originally, whether in the East or West, the barrels were made of red iron sheets wrapped on steel bars to forge and rolled the tube, and two to three sections of iron sheets were forged and welded into a complete barrel.

But at this time the barrel was just a thick blank, and the original hole was very small. You need to use a steel drill to drill out the smooth and straight gun chamber. At this time, the deformed steel used in the drill bit was not very hard, and you can only drill about an inch a day, and one can be drilled in a month.

Therefore, 99% of the time spent on building a bird gun is wasted on this barrel. Moreover, the quality is very worrying, and it will explode sooner or later.

Even the best quality Longqing rifle will have a chance of blowing up the chamber after firing a thousand times.

For the safety of the soldiers, Zhao Hao had to stipulate that each rifle had to be forced to retire and replace it with a new gun after one year of service or the number of firings reached 800 times.

Fortunately, the retired rifles can be sold to the Indian Turkish King and Arab tribes for ten times the price. Because even the retired rifles of the Coast Guard are safer than the Turkish muskets they used before, and shoot farther and more powerful, and are very popular among overseas customers.

Now the manufacturing process of the barrel is greatly simplified, saving the time-consuming and laborious forging process. The barrel blank cast by 01 is directly polished into a solid steel pipe of one meter one, and then drilled directly with a deep hole drilling machine.

The cast iron drilling machine increases the carbon steel drill bit, which greatly improves the efficiency of drilling the barrel. Zhao Shizhen told Zhao Hao that if you use manpower as power, you can drill a barrel in six hours.

If a water truck is used to drive the drilling machine, the drilling time can be further shortened to four hours per piece!

"Good guy!" Zhao Hao called out good guy, how many times has the efficiency improved?

"The biggest benefit of this kind of barrel is that it has no gaps and is made of steel." Zhao Shizhen handed one to Zhao Hao and said: "After testing, there is no risk of shooting 20,000 shots. The reason why it is said to be 20,000 shots is because we only tested 20,000 shots..."

"Seamless steel pipe..." Zhao Hao murmured at the hole in the steel pipe.

"Seamless steel pipe? Uncle can always name it accurately!" Zhao Shizhen exclaimed: "This kind of seamless steel pipe is really the king of gun barrels. We also tested the use of 'Thor's gunpowder' as the launching medicine, which can be completely withstand it!"

The so-called Thunder Ghost Powder is a small amount of nitrified starch prepared by adding a small amount of 04 to the black gunpowder, which can greatly increase the power of the explosion. Of course, this is also a top-secret test product that is only tested.

"Okay, very good." Zhao Hao nodded with satisfaction, not only for the barrel of this gun, but also for the fact that the institutes had built the Ming Dynasty's industrial system.

Then the researcher inserted the drilled barrel into the manual wire puller, pulled it back and forth at one position dozens of times, then cut out a pair of rifles on the inner wall of the barrel, and then adjusted the position and cut it down. After repeating for about a hundred times, the rifle of a gun will be pulled.

Rifting is not a new thing. The Europeans would rifle the barrel decades ago. Zhao Shizhen's rifling machine was first seized from the Portuguese in Macau.

Because rifling can greatly increase the range and hit rate. However, it is very difficult to load a rifle in front, and the musketeer needs to use a hammer to hit the bullet rod before putting the lead ball into the chamber. As a result, one shot of the rifle can fire three shots, which is obviously unbearable.

Therefore, there is almost no sign of the rifled gun on the battlefield.

However, under Zhao Hao's suggestion, Zhao Shizhen developed a new type of bullet, which solved this problem while retaining the advantages of rifled rifles.

Not bad, it's Minnie.

This conical lead bullet with hollow tail has a diameter slightly smaller than the diameter of the gun chamber, so it is very smooth to load.

A small plug is used to block the hole at the bottom of the warhead. When fired, the gas presses the plug and squeezes into the hole, forcing the bullet to expand, stick to the rifle, and seals the gap between the bullet and the gun chamber, making the gas unable to leak out. It also allows the warhead to rotate at high speed under the rifle pressure, accurately hitting a target kilometer away!

This Minni rifle, named by Zhao Hao as the Wanli rifle, is the ultimate musket he launched in his life!

A more powerful version will be left to future generations...
Chapter completed!
