Although it didn't go well, looking at the people in the bullet workshop who were busy all night, racking their brains to think about a problem, and even after some of the hair on their heads had been significantly reduced or grayed.

Rao is Li Yuanji didn't want to reprimand them anymore, they made as much contribution as they could, and it was obvious that they had done their best in this matter.

And in this regard, Li Yuanji is actually helpless.

He can't just blame other people, because it's not an easy problem to solve.

And at this moment, Li Yuanji finally understood why so many people in later generations would say that if you learn mathematics, physics and chemistry well, you don't have to worry about crossing the sentence.

Mathematics, physics and chemistry are now used, but due to their own only elementary Chinese and self-taught advanced Chinese level, in many ways can only be regarded as a basic entry level.

It's okay to occasionally make a suggestion and guide the general direction, but as for doing those delicate researches, it's purely looking for death.

The primer of the bullet was mostly mine mercury, which was later replaced by lead azide, which is safer, more environmentally friendly and stable.

But no matter which of the two, Li Yuanji can't do it, although he roughly knows some of the production methods of thunder mercury, but the problem is that there are many things that are not available now, and those production methods only exist in memory, and that memory is extremely vague.

"Your Majesty, after many tests, the results show that the most practical is the use of flint scheme, but this scheme is very unstable, under the test in the laboratory, only more than 20 rounds of a hundred bullets can be fired smoothly, and the success rate of other methods is not even as good as one percent." Director Liu reported with a tired expression.

Director Liu's full name is Liu Sancai, and as his name suggests, he is indeed quite talented.

It only took two years for him to study all the elementary textbooks on his own, if it weren't for his ambition not to be an official.

Or after studying these elementary textbooks, he still feels as if there are more things to learn, and he is not satisfied with the status quo, so he came here.

Otherwise, with Liu Sancai's talent, it is not difficult to get an official position in the scientific examination.

I have to say that Liu San is the right step at this time.

After entering the Academy of Sciences, Liu San got the intermediate textbook as he wished, which contained more knowledge points and richer knowledge.

There are plenty of opportunities to experiment and consolidate what you've learned.

That's it, in just three years, Liu Sancai was promoted to the director of the bullet workshop, and he was also the first director.

It's just that the current Liu San is much darker than before.

After all, the previous Liu Sancai can be said to be a person blocking and killing, and the Buddha blocking and killing the Buddha, and he went smoothly along the way, never encountered any decent difficulties, and was the leader in the entire Academy of Sciences.

It was precisely because of his ability that his superiors took a fancy to him, so he was promoted to become the director of a department.

But a few months passed, a large number of personnel, funds, and resources were thrown over, but he failed to solve the final problem, and he also injured two people because of the test.

"Use flint friction to start a fire and then ignite the gunpowder?" Li Yuanji thought for a moment.

"Exactly, the problem with this method is that the flint does not catch fire every time it is rubbed, and it ignites the gunpowder accurately, and even sometimes when the failed product is opened, the flint will fall off or break, which will cause the flint to fail to ignite, resulting in a failure to launch." Liu Sancai talked about the experience of failure, and looked at Li Yuanji with an expectant face, hoping to get some help.

Although Li Yuanji has never made any mention of the bullet workshop, Li Yuanji is still very helpful to other workshops, and even many of the problems encountered by the workshop before were solved by Li Yuanji.

And these past cases have also made Li Yuanji's reputation in the Academy of Sciences more and more famous.

Of course, one of the reasons is that in the past year or two, Li Yuanji has rarely put forward some proposals in the Academy of Sciences.

The best way to maintain one's godhead is to do nothing and keep one's myth alive or bring it up only when you're sure of it, and then continue to solidify one's godhead.

"Flint friction requires angle and force, and every point of error can lead to the failure of the fire, which can lead to the failure of the whole process. Moreover, the primer is subject to the size of the bullet caliber, and the two flints must be polished into thin strips, which cannot guarantee its hardness, so it is not surprising that there will be breakage. Li Yuanji nodded.

For 8 mm caliber bullets, even if the propellant part of the tail part will be larger, it will be no more than one centimeter at most.

Excluding the shells, this diameter may be only nine millimeters, or 9.5 millimeters.

Remove some others, such as the recess at the tail, which is used to push the bullet into the card slot, which can be firmly fixed on the bolt, which is not very useful when propelling, but it is absolutely impossible to return the bullet without this, and there is only one result, that is, the bullet is stuck in the launch compartment and cannot come out.

Therefore, the width that can be provided for the placement of the primer is only about 8 mm at most.

The two flints are to be arranged crosswise, one is fixed, and the other is attached to the primer, and with the impact of the firing pin, it is violently pushed forward, so as to rub against the other and start a fire.

But the problem is that the so-called flintstones are actually those specific stones that can produce sparks when two pieces collide.

Perhaps many people will think of the kind of flint used by Bei Ye, but it is not, but similar to those stones laid under the railway in later generations.

For gunpowder, such a small spark is enough to ensure that the gunpowder can be ignited.

But how hard did the two flints hit? And even then, there is no guarantee that a spark will be produced every time, so how hard will the friction be after polishing it into thin strips?

When you think about it, it's not surprising that there is such a large failure rate.

"Have you considered new materials?" The success rate of the flint's method was too low, but Li Yuanji had no way to get other materials, so he could only remind them.

Now, not to mention anything else, you can't even make a match, because this also involves a lot of chemical knowledge.

"New materials?" Liu Sancai was stunned for a moment, and then shook his head with a bitter face and said: "How can new materials be so easy, it's not that the ministers don't want to do it, but they really can't do anything." ”

"No matter how difficult it is, you have to find a way!" Li Yuanji sighed, picked up a complete bullet, and took a bunch of parts and looked at it.

It was found that there was basically no problem in other aspects except for the primer problem, although this may only be produced in the laboratory, but as long as there is not a large batch of equipment troops, it is no problem.

"I will let the gunpowder workshop do research in this area, and the main task on your side is to improve the production process to ensure that there are no errors in the bullets produced.

Li Yuanji felt that it was indeed a bit embarrassing for them to engage in this research, after all, the study of bullets focused on the ratio of materials, the installation location and proportion of parts, and so on, rather than the study of gunpowder.

And gunpowder is an absolute top-secret formula, everyone only knows that the current gunpowder is much more powerful than before, but they don't know what changes have taken place in it?

I also don't know that the granular gunpowder of the current bullet Liser is actually no different from other gunpowder, but its shape has been changed to a certain extent.

As for research, the gunpowder workshop has not stopped, they are researching all kinds of different gunpowder, with only one purpose, to develop gunpowder that is more powerful and safer than the existing gunpowder.

Giving them this task, although it is also bottomless, is at least much more reliable than handing it over to the bullet workshop.

"Your Majesty, the minister will rectify it as soon as possible......" Liu Sancai's face turned pale, and he nodded again and again in agreement.

Regarding the problem of different bullet sizes, in fact, there is no way, there is no equipment here, all the processes are done manually, and there are errors that are certain.

Although they have singled out many obvious errors and some errors in measurements, no one can guarantee that those measurements will be error-free.

And the way they measure is to use a string to measure, but the accuracy can only be accurate to the millimeter, and then it will be a bit fantastical.

Therefore, mechanization is particularly important.

Because of the mechanized production of things, there is another method of detection in this era, such as weighing, which can be used to ensure that the bullet is qualified or not, which is very old-fashioned, but very effective.

He commanded Song Zhong, and then Li Yuanji left here.

I have watched everything that should be seen, and I have also mentioned everything that should be mentioned.

What can be done, Liu Sancai has also made a guarantee, and if he can't do it, he didn't embarrass him, but handed it over to others to do.

There is a specialization in the art industry, and Li Yuanji does not expect to rely on one person to solve all problems.

The development of the past few years, although it is not said whether this problem can be solved, but the most basic benefits have been revealed.

At least when there is a problem, it is better to let people know which department to hand it over to solve the problem, isn't that a kind of progress?

As for what kind of way the gunpowder workshop will take to solve this problem, Li Yuanji is not clear, and he can't interject.

However, after experiencing this incident, Li Yuanji also realized the importance of chemical talents.

Of course, limited by their own knowledge, it is obviously impossible to cultivate senior talents in one step.

But fortunately, I know all the junior high school chemistry, and most of the high school chemistry, which is enough for this stage.

As long as these students can be guaranteed to learn this, they can use this knowledge to experiment on their own, to explore on their own, and to record different results every time, which is a new discovery.

Over time, the results will be felt.

Therefore, Li Yuanji gave himself another task, writing a chemistry textbook......
