Joseph is indeed burying his head in the laboratory to look like a new thing, that is, the new toy he is going to give to Napoleon for his use in Italy-the Mini bullet rifle.

　　 In this era, there are already wired rifles. But these rifled guns are almost useless except for hunting because their loading speed is too low. (The bullet of the original rifled gun was slightly thicker than the barrel, so when the bullet was loaded, the gunman had to use a hammer and a push rod to force the bullet into the barrel. This process was time-consuming and laborious. As for the ordinary muskets, they have already shot seven or eight shots, but the muskets can only take one shot)

　　 But the appearance of the Mini Bullet changed everything.

　　In the original history, this bullet was invented by French Captain Claude Edirne Minne and Captain Henri-Gustave De Vikenet in about 1849.

　　This kind of bullet is slightly smaller than the caliber of the rifle, so it solves the embarrassing situation of the old rifle's front loading bullets because the bullets are too large, which can not be inserted into the barrel or block the barrel. Mini bullets can be easily pushed into the barrel with a push rod. Thereby greatly increasing the rate of fire.

　　The bullet is threaded around the body to match the rifling, and the middle of the thread is lubricated with animal oil. (Later, the British also learned this technique and brought it to India. But they didn’t want to cause Indian soldiers to refuse to use these bullets because they were smeared with lard or butter. They used this as a fuse and triggered India. National Uprising.)

　　The bottom of the bullet uses cork material. When shooting, the gunpowder gas impacted the cork, and the cork suddenly supported the bullet after an instant impact. Because the bullet is expanded, the bullet itself can be used to complete the chamber seal at the moment of launch without leaking gunpowder gas and causing the loss of the kinetic energy of the bullet. This solves the problem of chamber sealing of the old-style front-loading gun, and greatly enhances the rate of fire, range and safety of the gun (good sealing is not easy to cause gunpowder residue to block the barrel and cause explosion).

　　 This kind of bullet, although it was invented only a few decades later, at this time, it is actually not difficult to realize it technically. The tactical advantage it brings is very huge.

　　First of all, it makes the rifled gun completely catch up with the musket in the loading speed, making the musket as a weapon almost only has the only advantage of being cheaper.

　　A general smooth-bore rifle has an effective range of no more than one hundred yards, but a rifled rifle that uses a Mini bullet can effectively shoot targets five hundred yards away. This makes the firearm of the rifle in the hands of the infantry many times longer.

　　Before the use of such bullets, both British and Russians believed that "bullets are fools, bayonet is a hero." They are accustomed to advancing to the closest distance against the opponent's bullets on the battlefield, and then after another salvo, using bayonet charges to solve the problem. However, if their opponents use Mini bullets that can fire effectively from five hundred yards away, then the bravery of both the British and Russian troops will become a joke. The status of hand-to-hand combat also declined sharply.

In the musket era, the infantry had to line up in a tight formation to fight because of the threat of cavalry. (Of course, besides this reason, the morale of the army is also a major cause. If the morale is not enough, the skirmishers will disperse. It will really disappear on the battlefield.) But with the Mini bullet, the cavalry will charge the infantry again, and it will be dead. The status of the cavalry has dropped significantly.

　　 In addition, the artillery tactics were also greatly affected. In the musket era, when the artillery used shot or grape bullets, its effective range was greater than that of the rifle in the hands of infantry. Therefore, artillery can be used as an offensive weapon in field battles, pushing it at the forefront of the queue.

　　 But the emergence of the Mini Bullets made the range of infantry weapons suddenly surpassed the range of the cannon shot or grape bullet. Although the solid shells used in the artillery have a much longer range than the Mini shells, they are too inefficient to fight loose skirmishers due to precision problems. So if you want to push the cannon in front at this time, you can use it for attack. The gunner would become a living target for the opponent's infantry. As a result, the artillery had to retreat and was only used as a support weapon in the logarithm.

　　 Even Cantaloupe, which has changed the course of history, will return to the position of auxiliary weapons from the current position where it almost becomes the main weapon due to the problem of throwing distance.

　　 However, this weapon still has a huge flaw, that is, its technical threshold is too low, so that only a glance can understand what this is all about. Therefore, once this weapon is used, it will not be long before the related technology will be acquired by others. These people may be enemies of France, or enemies of the Bonaparte family in business.

　　 Therefore, this kind of thing can only be put into use before Napoleon reaches Italy. The Bonaparte family relied on the victory and support brought by this weapon to ascend to a high political position, and used this position to suppress and defeat their business enemies.

　　 Of course, Joseph, as a traverser, naturally knows that this kind of weapon is ultimately replaced by a bolt-action rifle. He didn't mean to squeeze toothpaste. It's just that some of the front technology of the rear-mounted bolt-action rifle is still difficult to achieve today. For example, bolted rifles must use steel, not wrought iron, but in this era, the most advanced steelmaking in the world is still crucible steelmaking. Its output and efficiency simply cannot meet the requirements.

The 　　 bullet experiment was actually successful very early, but the design of the rifle was a bit of a hindrance. The Mini bomb needs gunpowder gas to support the bullet, which means it needs to use gunpowder that burns faster. It is not difficult to achieve a faster burning speed, but a faster burning speed brings two problems. One is that the chamber pressure is rising too fast, and the other is that the chamber pressure is falling too fast. The former leads to a high peak pressure in the chamber, and it is easy to explode the chamber, while the latter leads to the average pressure in the chamber is not high enough, and the speed of the bullet is not fast enough.

　　In order to avoid blasting, the barrel must be thickened, which makes the rifle too heavy, and consumes too much metal, which increases the cost. For this reason, Joseph designed the barrel to be a round truncated cone shape with a thick back and a thin front, but how thick the thick place should be, and how thin the thin place can be, can only be solved slowly by experiment. Therefore, these things, which are not at all difficult in principle, occupy a lot of Joseph's time. So much so that the number of words he wrote to Fanny has been reduced.

　　 However, no matter how busy you are, you must pay attention to the combination of work and rest. At least, it must be the case for mental workers. So Joseph stipulated that researchers should have one day off every ten days and work no more than 12 hours a day. As for himself and senior researchers like Lavoisier, they have two days off every ten days and work no more than six hours a day. As for manual workers, there are all over the streets, unless the skills are so superb that it is difficult to replace them, Joseph has no time to care for them.

　　 Today is not a break time, but Joseph received a letter from Lucien, saying that there is a millionaire who wants to negotiate a big deal with himself. So Joseph handed over the affairs of the institute to Lavoisier and drove back to Marseille. And met Stephen Girard in the manor in Marseille.

　　 Joseph only knows a rough idea about history. In his previous life, he didn't even know who Saint-Just was, so naturally he would not know. The French bald with a taste of Bordeaux in front of him is a legend in American history. During the War of Independence in North America, Stephen Gillard, who started by smuggling arms to the Continental Army, was the shipping magnate of North America and the first monopoly with personal assets of more than 10 million U.S. dollars in American history. However, this is all later. At this time, it was just when his hegemony had just taken off.

　　Steven Girard was born as a sailor and is particularly interested in all kinds of ships. When he saw the "Black Pearl" for the first time in the port of New York, he was full of interest in it~lightnovelpub.net~ After a little understanding of the performance of the "Black Pearl", he immediately calculated it , If this kind of ship can reach 500 tons, its efficiency will far exceed the conclusion of ordinary sailboats. So, this French-American with a keen sense of smell followed the "Black Pearl" back to France again.

In the next two days, Joseph and Stephen Gillard had arduous negotiations. The two sides cried poorly, poured chicken soup on each other, and said that "negotiations have enhanced mutual understanding" and finally reached a strategic partnership. relationship.

　　According to the final agreement signed by the two parties, Stephen Gillard will order seven flying shear ships with a payload of 500 tons from the shipyard affiliated to the Bonaparte Research Institute at a time, and prepay the purchase price of all five ships. The rest will be paid when the vessel is delivered.

The Bonaparte shipyard needs to fully transfer Steven Gillard’s technology related to the construction of this flying shear ship, and ensure that Steven Gillard provides a salary not lower than 1.5 times the salary of the French counterpart , Sent technical instructors to Stephen Gillard’s shipyard in New York, and ensured that the New York Gillard Shipyard could master flying shear craftsmanship within two years.

　　Steven Girard promised that in the next fifteen years, for every flying shear ship produced by the Girard Shipyard, it will pay a fee for the use of technology to the Bonaparte Institute at a price of one dollar per ton of deadweight.

　　 Bonaparte Institute guarantees that it will not sell this technology to other manufacturers during this period. When selling flying shears to other companies in North America, Stephen Gillard needs to be compensated at $1.5 per ton of load.
