Building artillery is not a difficult problem for Li Shouhan.

His Xinren company is known for its so-called handicraft manufacturing. All kinds of ancient artillery, armor, decorative swords, flintlock pistols, arquebuses, are all part of the company's business. There was once a Frenchman, extremely perverted, who placed an order with a very simple request, that is, to make all kinds of artillery and guns without a steam engine as a power base. Let's re-enact the Battle of Tieruo and see if Napoleon would have failed if he had mastered the most advanced weapons on the eve of the Industrial Revolution.

In fact, Napoleon and his nemesis Nelson, Wellington, Kutuzov and others lived in a time when the guns they used were very different in basic construction, they were all cast in bronze or iron, muzzle loaded, and fired solid spherical projectiles. Copper has good ductility, is not easy to explode, and the bore is resistant to fire powder corrosion, and until the middle of the nineteenth century, the performance of iron artillery was completely overwhelming, and it was excellent during the Napoleonic Wars and the American Civil War.

All right! The construction of our artillery began with the bronze cannon, but it started with the highest level of the bronze cannon, the Napoleonic bronze cannon!

Thanks to the ancestors, because of the need to mint copper coins privately, there is no shortage of copper in the treasury. Moreover, with Li Shouhan now hundreds of thousands of words per minute, he doesn't care about these coppers at all.

In addition, countless water wheels and water drains have been erected in the area along the river. The concept of a waterwheel as a source of power led many craftsmen to think about using water power to do things that could not be done by humans. For example, Feng Mofeng took the lead in manufacturing hydraulic forging hammers and boring machines. For the manufacture of artillery, Li Shouhan decided to use forging bronze cannons, because the large-scale use of roller bearing vernier calipers has completely removed the obstacles, and the hydraulic forging hammer made by Feng Mofeng makes forging bronze concoctions possible.

All right! With basic motivation and raw materials and skilled workers, what are we waiting for?! Start!

According to the production process of Gong Zhenlin and Wu Yunduo, a cylinder was first made of steel casting, one end was closed, and there was a solid cylinder in the inner center, the cylinder was 122 mm thick and 20 cm shorter than the cylinder. Both the cylinder and the steel column are polished and ground so that the maximum error does not exceed 0.05 mm. The refractory bricks are crushed, ground into a fine flour-like powder, then mixed with a small amount of animal oil, and the thinner is applied layer by layer to the surface with a small brush.

Pour the melted bronze into it, the height should be slightly lower than the opening, after the bronze is cooled, it is the shape of the cannon, and the volume occupied by the round steel column in the middle is the inner chamber of the cannon. Wait for the bronze temperature to drop to 700 degrees, that is, the solid red state, and then put a steel ingot with a thickness of 15 cm from the opening of the round steel cylinder, and the outer diameter of the steel ingot should be as large as the inner diameter of the cylinder. The maximum error shall not exceed 0.05 mm, the inside of the steel ingot has a diameter of 7 cm, a deep pit of 5 cm, and then use a forging hammer to forge the steel ingot, in this way, the blow pressure of the forging hammer can be evenly transmitted to the whole body of the bronze cannon, and the forging hammer is used to carry out high-density forging until the steel ingot is flush with the cylinder, and then drill a hole in the bulge of the gun tail, tie the wire rope, and then use the hydraulic machine tool to take the bronze cannon out, after cooling, polish and grind it. The bronze cannon made in this way is lightweight, has a long life, and can fight farther. For example, the 122 mm bronze cannon, which uses maroon gunpowder, can shoot more than 14 miles. However, the recoil of this kind of artillery is also very large, and it is unrealistic to make a hydraulic reset machine now, so Li Shouhan decided to add a muzzle brake to the artillery, and when the shells are put in, wrap the shells with linen, which can have a good sealing effect

It's a pity that Li Shouhan hasn't built a large hydraulic press yet, and if he had a hydraulic press, then the quality of the artillery made by his own extrusion method would be better. Faster and easier. The price will also be cheaper.

After casting, forging, boring, grinding, rapid cooling, adding gun lugs, tying iron chains, using water to pull the gun body out of the steel mold, send it to the drilling machine to drill holes, and create a fire door. There was no way, the artillery at this time was ignition and ignited the propellant to push the shell out of the chamber. Therefore, it is necessary to open the fire door, if there is no fire door, to use a not very vivid analogy, it is that the East is undefeated, so I have to practice the Sunflower Treasure Book.

After weighing and measuring, Li Shouhan could confirm that he had obtained the first bronze forged cannon with a caliber of 122 mm, which should be a very good twelve-pounder gun of this era according to the conversion of caliber and weight.

However, looking at the copper that flowed in like water, Shouhan still felt a little painful, "Is the cost of making cannons from copper too high?" ”

To Li Shouhan's surprise, at the beginning of the experimental stage, Feng Mofeng's unintentional move allowed him to create a more powerful weapon accessory.

In order to save real expenses, Feng Mofeng, who adheres to the fine tradition of the Chinese nation's diligence and thrift, first built a steel pipe with an inner diameter of 17 mm with nine turns of steel, divided the steel pipe into two halves, and polished the inside. Then a steel rod with a diameter of 8 mm was created.

Then, fix the steel pipe and steel rod, fix the steel rod in the middle of the steel pipe, and then pour the clay that is ground into fine powder, and then burn the medium carbon steel red, forge, and then burn red to translucent after forging, and then squeeze the red-hot steel rod into the steel pipe with a water press, and then slowly rotate the steel rod in the center of the steel pipe, and when its color is completely blackened, the steel rod is pulled out, and the steel pipe is separated, and a nearly perfect steel pipe is obtained.

When he brought the steel pipe and process test record to Li Shouhan, Li Shouhan's first reaction was, my God! Isn't this the best musket barrel?! If it is then rifled, it is red-burned, and the whole is quenched with horse urine mixed with cold salt water. Plated with copper, it's a perfect rifled barrel!

He grabbed Feng Mofeng's hands, "Old Feng, you are now a shareholder of Hanyuan Firm!" ”

Shouhan knows very well that the biggest cost of today's muskets, whether they are arquebuses, flintlock pistols, or the so-called Zawa iron cannon of the Japanese, is the manufacture of the barrel.

The Han Yuan firm, or Li Shouhan's own Han Yuan firm, is the largest steel producer in the Annam region, and qualified steel is not a big deal for Li Shouhan, relying on crucible steelmaking technology, as well as the small blast furnace technology that is about to start, as long as others do not go to the open-hearth furnace steelmaking before him, his steel output will rank first. Now that he has the technology to manufacture gun barrels, to put it mildly, as long as he is given half a year, he can train an all-firearms unit.

Hum! What the Ruan family, what the Zheng family, the Li family, the Mo family! What should you do, what to do! The Mekong River Basin, no, is the Lancang River Basin, and the Red River Basin, a natural food production paradise, here, is destined to belong to the Chinese nation!

It is easy to work with more people, and it is easier to do things with more money.

The shipyard worked overtime day and night to catch up with the progress, and the shipwrights worked more than six hours a day, and for each overtime hour, Li Shouhan gave half a day's overtime pay. Of course, on the premise of completing the progress of the day's work.

Under Li Shouhan's investment regardless of the cost, on the 17th day of the lunar month of the 47th year of Wanli, two scissor sailing ships with a tonnage of 2,000 materials equivalent to 600 tons were raised and launched.

As Li Shouhan, Feng Mofeng, Wang Quan and others swung their sledgehammers to knock the wooden blocks under the big boat into the air, the wooden boat slowly slid towards the sea along the wooden frame. With a few violent vibrations, the big ship floated silently on the sea level.

"Raise the sails!"

"Raise the sails!"

A few loud slogans, dozens of white sails under the operation of the sailors, full of wind, a beautiful spin, sailed towards the distant sea. All the way along, there was the rumbling sound of cannons, which was the sailors conducting shooting training at sea, and it was also a tribute to the boatmen!

The sailors happily carried out adaptive training and artillery drills, but Li Shouhan, as the designer and their commander, was not satisfied with such a warship.

In terms of structure and other technical parameters, scissor sailing ships are not very suitable for gunboats, especially not suitable for loading a large number of guns. In order to compensate for this shortcoming, Li Shouhan had to make a lot of reinforcements to the keel and deck. Even in the eyes of the craftsmen, the craftsmen used nine steels as the keel of the ship. This behavior made the craftsmen criticize, but the sailors were greatly moved.

"It seems that in order to achieve absolute superiority at sea. The displacement, speed, and number of guns of the ship are all issues to be considered! ”

Shouhan stood on the watchtower of the pier, looking at the gunboats speeding on the sea, and sighed secretly with regret.

His own sea power is in its infancy, and it is too weak compared to the old maritime countries such as Spain, Portugal, the Netherlands, and the United Kingdom. The number of ships, the number of sailors, the number of artillery is not enough to see. "According to the principle that a big ship is better than a small ship, more ships are better than fewer ships, and more guns are better than fewer guns, how can I beat these guys?!" In anguish, he slapped the railing of the watchtower with his palm.

Suddenly, a thought crossed his mind like a bolt of lightning!

If that thing were to be modified and installed on the second-floor gun deck, would it become an absolute killer?

Shouhan was originally because he designed and manufactured the 107 rocket launcher, and then, several collaborators with ulterior motives intended to take the design results of this stupid boy to rob the bank cash truck! Therefore, regarding the design of the 107 rocket launcher, Shouhan can be said to be unforgettable, even if he forgets who he is, he will not forget these things.

"Although there are no conditions to make nitroglycerin explosives at the moment, the warhead of the 107-mm rocket launcher is enough to hold 5 kilograms of black powder with copper oxide powder, which can be obtained by heating patina, that is, copper hydroxide. There is no detonator to detonate, well, you can install a steel needle at the front of the warhead, and when the rocket launcher hits the target, it will insert it into the target's body, and then wait for it to explode. The ships of this era were often a few feet thick with planks, which were enough to receive such enthusiastic guests! "Propellant. Well, propellant, you can mix potassium nitrate with sugar and sulfur to make zuò propellant, sugar, sulfur and these things are not lacking in Annam. It is said that the bearded people in Afghanistan and the Middle East use this as an alternative product, which is simple, cheap and efficient, and the fly in the ointment is that the smoke is bigger. ”

Shouhan was very proud of the 107mm rocket launcher he designed and manufactured, and for the ship-based version of the rocket artillery, he considered designing only one main propulsion nozzle at the tail of the rocket artillery, the remaining six under the warhead, and six transverse nozzles to provide high-speed self-rotation for the missile body. Such a design. The shooting accuracy will be much improved, and if you shoot directly at a range of 4 km, it will be much more accurate than the bronze gun. In order to prevent the tail flame of the rocket launcher from hurting the sailors in the cabin, he deliberately shot the sluice gate and deflector at the tail of the rocket launcher, and when the rocket launcher was launched, the fire tongs were inserted from the small hole in the back to ignite the rocket artillery, and the deflector was four, showing an X-shape, which was responsible for discharging the fireworks after the rocket launcher was ignited to one side to prevent injury to the sailors. Its barrel is a little longer, about 3 meters long, and the barrel diameter is 0.05 mm, which allows the rocket to accelerate to its maximum speed in the barrel, thus improving the accuracy of shooting.

In the future, when fighting with enemy ships at sea, you can use the long-range shooting of bronze cannons to lure the enemy to break through, hehe, the naval shooting norms of this era are no more than 600 yards, 4 kilometers? It will definitely be regarded as a cowardly expression by the enemy. When the target is within 4 km, it begins to carry out intensive, saturation strikes with rocket artillery. Hum! In the future, Lao Tzu's naval rocket artillery configuration was 7 guns on one side and 4 barrels on one side. The rocket launcher can be rotated up and down, left and right, and is very flexible. In fact, Li Shouhan's bronze cannon is just a transitional stage, his ideal is a front-loading rifled gun, but there are many difficulties in rifled guns, so in at least 10 years, the real big killer of the navy is rocket artillery! However, what Li Shouhan did not expect was that it took a full hundred years for the shipborne version of the rocket artillery to be withdrawn from the army, and one of the main reasons was that it was so easy to use, although it was very different from the original idea of his designer.

"Well, it's time for someone to go to Myanmar to buy some fierce fire oil!"

Thinking of the scene when his navy fired napalm incendiary bombs in the future, Li Shouhan smiled very fiercely.

"Hmph, one shot for one ship! Absolutely cost-effective! ”
