Making cannons was not a difficult problem for Li Shouhan.

The Xinren company he works for is famous for its so-called handicraft manufacturing.All kinds of ancient artillery, armor, decorative swords, flintlock guns, and matchlock guns are all within the company's business scope.There was once a Frenchman who was extremely perverted and placed an order. The request was very simple, that is, to manufacture various artillery and guns without a steam engine as the power base.Let's replay the Battle of Waterloo to see whether Napoleon will fail if he has mastered the most advanced weapons on the eve of the Industrial Revolution.

In fact, in the era of Napoleon and his rivals Nelson, Wellington, Kutuzov and others, the artillery they used was very different in basic structure. They were all made of bronze or iron, filled in the muzzle, and fired a solid spherical shape. projectile.Copper has good ductility, is not easy to explode, and the inner bore is resistant to gunpowder corrosion. Before the middle of the [-]th century, its performance could completely overwhelm iron artillery, and it performed well during the Napoleonic Wars and the American Civil War.

alright!Our artillery construction starts with bronze cannons, but it starts with the highest level of bronze cannons, Napoleon bronze cannons!

Thanks to the ancestors, because copper coins are minted privately, there is no shortage of copper in the treasury.Moreover, Li Shouhan doesn't care about these coppers at all now that he has hundreds of thousands of Wen every minute.

In addition, countless waterwheels and water drains have been erected in the area along the river.Through the promotion of the concept of waterwheels as a source of power, many craftsmen began to think about using water power to perform tasks that could not be achieved by human power.For example, Feng Mofeng was the first to manufacture hydraulic forging hammers and boring machines.For the manufacture of cannons, Li Shouhan decided to use forged 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 made the production of forged bronze cannons possible.

alright!With basic power, raw materials and skilled workers, what are we waiting for? !start!

According to the production process of Gong Zhenlin and Wu Yunduo, a cylinder is first made of steel casting, one end is closed, and there is a solid cylinder in the center of the interior. The cylinder is 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.Break the refractory bricks and grind them into flour-like powder, then mix a small amount of animal oil, and use a small brush to spread the thinner on the surface layer by layer.

Pour the melted bronze into it, and the height should be slightly lower than the opening. After the bronze cools, it will be in the shape of a cannon, and the volume occupied by the round steel column in the middle will be the inner bore of the cannon.Wait until the temperature of the bronze drops to 700 degrees, which is solid red and bright, and then put a steel ingot with a thickness of 15 cm from the opening of the round steel cylinder. There is a pit with a diameter of 0.05 cm and a depth of 7 cm inside, and then the steel ingot is forged with a forging hammer. Forge until the steel ingot is flush with the cylinder, then drill a hole in the protrusion of the gun tail, tie a steel wire rope, and then use a hydraulic machine tool to pull out the bronze gun. After cooling, polish it grind.The bronze cannons made in this way are light in weight, long in life and can hit farther.For example, the 5mm bronze cannon uses chestnut gunpowder and has a range of more than 122 miles.However, the recoil force of this kind of artillery is also very large. It is unrealistic to develop a hydraulic reset machine now. Li Shouhan decided to add a muzzle brake to the artillery. sealing effect

It is a pity that Li Shouhan has not built a large-scale hydraulic press. If there is a hydraulic press, the quality of the artillery made by the self-extrusion method will be better.Faster and easier.The price will be cheaper too.

After casting, forging, boring, grinding, rapid cooling, adding lugs, fastening iron chains, using hydraulic power to pull the gun body out of the steel mold, sending it to a drilling machine to drill holes, and making the fire door.There is no way, the artillery at this time is to ignite the propellant by igniting the propellant, and push the shell out of the barrel.Therefore, it is necessary to open the fire door. If there is no fire door, to use an inconspicuous analogy, it is Dongfang Invincible, so I have to practice the Sunflower Book.

After weighing and measuring, Li Shouhan can confirm that he has obtained the first forged bronze gun with a diameter of 122 mm. According to the conversion of the caliber and weight, it should be a very good [-]-pounder gun in this era.

However, looking at the copper that flowed in like water, Shou Han still felt a little pained, "Is it too expensive to make cannons with copper?"

To Li Shouhan's surprise, Feng Mofeng's unintentional move during the initial testing stage allowed him to create a more powerful weapon accessory.

In order to save experimental expenses, Feng Mofeng, who upholds the fine tradition of the Chinese nation’s thrift and housekeeping, first made a steel pipe with an inner diameter of 17mm with nine-turn steel. After the steel pipe was divided into two halves, the interior was polished such as boring and grinding.A steel rod with a diameter of 8 mm was then fabricated.

Next, fix the steel pipe and the steel rod. The steel rod is fixed in the middle of the steel pipe, and then the inside is filled with clay that has been ground into a fine powder. Then, the medium carbon steel is burned red, forged, and after forging, it is burned red until it is translucent, and then Squeeze the red-hot steel rod into the steel pipe with a hydraulic press, and then slowly turn the steel rod in the center of the steel pipe. When the color is completely black, pull out the steel rod and separate the steel pipes, and you get a An almost perfect steel pipe.

When he brought the steel pipe and the process test records in front of Li Shouhan, Li Shouhan's first reaction was, my God!Isn't this the best musket barrel? !If it is rifled again, burnt red, and mixed with horse urine and cold salt water for overall quenching.Coat it with copper and you have a perfect rifled gun barrel!

He took Feng Mofeng's hands, "Old Feng, you are now a shareholder of Han Yuan Company!"

Shou Han is very clear that today's muskets, whether they are matchlock guns, flintlock guns, or Japan's so-called early and iron guns, the biggest cost is the manufacture of the barrel.

The Hanyuan Company owned by the General’s Mansion, or Li Shouhan’s own Hanyuan Company, is the largest steel producer in the Annan area. Qualified steel is not a big deal for Li Shouhan, relying on crucible steelmaking technology, and the upcoming With small blast furnace technology, as long as no one else started to make steel in the open hearth furnace before him, his steel production will rank first.Now that he has gun barrel manufacturing technology, to put it bluntly, as long as he is given half a year, he can train a full-arms army.

hum!What Ruan family, what Zheng family, Li family, Mo family!Do whatever you want to do!The Mekong River Basin, no, it’s the Lancang River Basin, and the Red River Basin, a natural paradise for food production. Here, it is destined to belong to the Chinese nation!

More people are easier to work, and more money is easier to do things.

In the dock, they work overtime day and night to catch up with the progress. The boatmen work more than six hours a day. For every overtime hour, Li Shouhan pays half a day's overtime pay.Of course, it is under the premise of completing the work progress of the day.

With Li Shouhan's investment regardless of cost, on the 47th day of the twelfth lunar month in the [-]th year of Wanli, two scissor sailboats with a tonnage of [-] materials equivalent to [-] tons were launched.

As Li Shouhan, Feng Mofeng, Wang Quan and others swung their sledgehammers, they knocked the wooden blocks under the big boat into the air, and the wooden boat slowly slid towards the sea along the wooden frame.Accompanied by several violent vibrations, the big ship floated quietly on the sea level.

"Raise the sails!"

"Raise the sails!"

With a few resounding slogans, dozens of sails, as white as clouds, were filled with wind under the control of the sailors. They made a beautiful spin and sailed towards the distant sea.Along the way, there was rumbling gunfire. It was the sailors conducting sea shooting training, and it was also a tribute to the boatmen!

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

In terms of structural and other technical parameters, scissor sailboats are not very suitable as gunboats, especially not suitable for loading a large number of artillery.In order to make up for this defect, Li Shouhan had to make a lot of reinforcements to the keel and deck.Even using the method that the craftsmen seem to be very prodigal, using nine steelmaking steel as the keel of the ship.This behavior made the craftsmen criticize, but moved the sailors greatly.

"It seems that in order to gain an absolute advantage at sea, the displacement, speed, and number of artillery of the ship are all issues to be considered!"

Shou Han stood on the watchtower of the pier, watching the gunboat speeding on the sea, sighing secretly with regret.

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

Suddenly, a thought flashed through his mind like a bolt of lightning!

If you modify that thing and install it on the gun deck on the second floor, can it become an absolute killer?

Shou Han originally designed and manufactured the 107 rocket launcher for himself, and then, a few collaborators with ulterior motives intended to use this silly boy's design results to rob a bank cash transport truck!Therefore, regarding the various designs of the 107 rocket launcher, Shouhan can be said to be unforgettable, even if he forgets who he is, he will not forget these.

"Although there is no condition to manufacture nitroglycerin explosives at the moment, the warhead of the 107mm rocket launcher is enough to hold 5 kg of black powder with copper oxide powder added. Copper oxide can be obtained by heating patina, that is, copper hydroxide. There is no detonator for detonation. Well, a steel needle can be installed at the front of the warhead. When the rocket launcher attacks the target, it will be inserted into the target’s body, and then wait for the explosion. Ships in this era are often several feet thick. Enough to accommodate such enthusiastic guests!" Propellant.Well, the propellant can be made by mixing potassium nitrate with sugar and sulfur. There is no shortage of sugar and sulfur in Annan.It is said that the bearded people in Afghanistan and the Middle East use this as a substitute product. It is simple, cheap, and efficient. The fly in the ointment is that the smoke is a bit big. "

Shouhan is very proud of the 107mm rocket launcher he designed and manufactured. Regarding the shipboard version of the rocket launcher, he considered designing only one main propulsion nozzle at the tail of the rocket launcher, and the remaining six are under the warhead, and six are horizontal nozzles. The projectile provides high speed self-rotation.Such a design. The shooting accuracy will be improved a lot. If you aim and shoot directly, within a range of 4 kilometers, its shooting accuracy will be much higher than that of the bronze cannon.In order to prevent the tail flame of the bazooka from hurting the sailors in the cabin, he deliberately shot the switchable gate and the deflector at the tail of the bazooka. There are four barrels in an X shape, which are responsible for discharging the fireworks after the rocket launcher is ignited to one side to prevent damage to the sailors.Its barrel should be a little longer, about 3 meters long, and the inner diameter of the barrel is 0mm larger than that of the rocket. This can make the rocket launcher accelerate to the maximum speed in the barrel, thereby improving the shooting accuracy.

In the future, when fighting enemy ships at sea, you can use the long-range shooting of the bronze cannon to lure the enemy to rush in. Hehe, the naval shooting specification of this era is no more than 600 yards, 4 kilometers?It will definitely be taken as a sign of cowardice by the enemy.When the target enters within 4 kilometers, it starts to use rocket launchers to carry out intensive and saturated strikes.hum!In the future, Lao Tzu's naval rocket launcher will be equipped with 7 guns on one side and 4 gun barrels on each gun.The rocket launcher can rotate up and down, left and right, very flexible.In fact, Li Shouhan's bronze gun is only a transitional stage. His ideal is a front-loading rifled gun, but there are many difficulties with the rifled gun. Therefore, for at least 10 years, the real killer weapon of the navy is the rocket launcher!However, what Li Shouhan did not expect was that it took a full hundred years for the rocket launcher shipboard version to withdraw from the army. One of the main reasons was that it was so easy to use, although it was quite different from the original idea of ​​its designer.

"Well, people should go to Burma to buy some fire oil!"

Li Shouhan smiled ferociously when he thought of the scene where his own navy fired solidified incendiary bombs in the future.

"Hmph, one cannon for one ship! It's definitely a bargain!"
