Chapter 1727 Wanli Rifle

Previous page        Return to Catalog        Next page

    Zhao Hao walked into the manufacturing research workshop and saw that the floor was wiped with a discernible light. Large steel machinery was placed neatly; various tools were neatly hung on the wall according to the type of boards; countless small parts were sorted and packed into boxes.  , stored one by one in vertical cabinets, with labels on the boxes. Those who didn¡¯t know it might have thought they were in a herbal medicine store.

    At first glance, it looked like it had been cleaned up in advance.

    "It's been a few years since my uncle came here. Everyone was so excited that they couldn't sleep and spent the whole night doing hygiene." Zhao Shizhen also felt that the people below were doing it too much, so he hurriedly laughed and said: "But we are usually not much worse than this."

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

    "A lathe, a planer, a drill, a grinder, a mill My dear, add a milling machine and a boring machine, and you'll have a complete work machine."

    "We didn't create this." Zhao Shizhen said without greed for credit: "They are all the results of the research and development of 03 Institute over the years."

    03 Mechanical Research Institute, the director is concurrently served by Zhang Jian, director of the research center

    Zhang Jian pushed up his black-framed glasses and said, "I'm ashamed. I haven't completed the primary task given by Master. No matter how much I do these basic tasks, I have no shame."

    "Hey, what Jingyang said is wrong." Zhao Hao shook his head decisively and said: "Why do we encounter so many difficulties in the development of the prime mover? It's because our foundation is too poor. If we do these basic tasks solidly, the manufacturing level will be improved.  Conquering the prime mover is a matter of course.¡±

    Zhang Jian¡¯s so-called top priority was named by Zhao Hao, who was still young at the time, as the ¡®Human Completion Plan¡¯.

    Zhao Hao¡¯s explanation for this naming that is incomprehensible to ordinary people is that the mission of this project is to improve the Zhang Jian steam engine into a prime mover that can provide power for all walks of life!

    Once this all-powerful prime mover is developed, it will revolutionize human beings' weak hands and become infinitely powerful, freeing human brains to deal with all problems, and will take human civilization to a new level unimaginable by previous generations!

    Zhang Jian and his researchers were all deeply attracted by the steam era described by Zhao Hao. They vowed to work hard throughout their lives to complete this 'Human Completion Plan'!

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

    Because the water pumped by a Zhangjian-type water pump is equivalent to the work done by fifty horses, and it can work day and night, the cost is only one-sixth of that of pumping water with horses and one-third of that of pumping water with people.  Therefore, not only did it quickly become a standard equipment in major mines, it was also installed beside canals to supply water to reservoirs and sluices.  It is also used in cities to pump water for water towers and supply drinking water to residents.

    At present, there are more than 500 steam engines produced, installed and maintained by "Jiangnan Power Company", covering Jiangnan, southern China and overseas administrative regions.  To some extent, it has even become a symbol of Jiangnan Group.

    But Zhao Hao was far from satisfied with this first-generation steam engine. Its main flaw was its 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, losing a lot of heat.

    In addition, this first-generation machine only used the vacuum formed by the low-pressure boiler cylinder during condensation, but did not use the tension of the steam. The energy loss was very large, so it had to be made very large and consume a lot of coal in order to provide a visible  motivation.

    Although in this way, there is no need to worry about the risk of the boiler exploding due to excessive steam pressure.  But it also made the Zhang Jian steam engine incompetent for the work of the prime mover.

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

    What made them even more confident was that Mr. Zhao, the North Star in the night, had already pointed out the direction - he told them that what you need to do is to use a sealed pressure cooker to boil water, and then use a pipe to pass the steam into a piston cylinder.  to push the piston downward.  After the piston returns, open the valve and discharge the steam into the condenser. This is the principle of the new generation steam engine.

    It doesn¡¯t sound difficult at all.  However, Zhang Jian and his colleagues never expected that every step of this 'Human Completion Plan' would be so difficult, with too many problems to be solved.

    For example, it took Zhang Jian¡¯s team nearly a year to fiddle with the valve between the cylinder and the condensation cylinder.  However, this brings new problems. The condenser will be filled with condensed water and air, and what should I do if it cannot be discharged?Fortunately, Europeans would have rifled the barrels of guns decades ago.  Zhao Shizhen's rifling machine was first captured from the Portuguese in Macau.

    Because rifling can greatly increase the range and hit rate.  However, loading the front-loading rifled gun was very laborious. The musketeer needed to hit the feed rod with a hammer to load the lead shot into the gun chamber.  As a result, the rifled gun fired one shot and the smoothbore gun fired three times. This was obviously unbearable.

    Therefore, there is almost no shadow of rifled guns on the battlefield.

    ¡°But Zhao Shizhen, under Zhao Hao¡¯s prompts, developed a new type of bullet, which solved this problem while retaining the advantages of rifled guns.

    Yes, it¡¯s the Migne bomb.

    This kind of tapered lead bullet with a hollow tail has a diameter slightly smaller than the diameter of the gun bore, so loading is very smooth.

    A small wooden plug is used to block the cavity at the bottom of the warhead. When fired, the gas presses the wooden plug into the cavity, forcing the bottom of the projectile to expand and close to the rifling, sealing the gap between the projectile and the barrel, preventing the gas from leaking out, and allowing the warhead to  It rotates at high speed under the pressure of rifling and accurately hits targets thousands of meters away!

    This Mini rifle, named the Wanli-style rifle by Zhao Hao, is, if nothing else, the ultimate musket he has launched in his life!

    The more powerful version will be left to future generations

    ps. Do you believe me when I say that I checked the information for several days?  Just so I don¡¯t talk nonsense I won¡¯t do it tonight.  (Remember the website address: www.hlnovel.com
