After returning from Xinzheng, Wang Sirui once again came to the ammunition factory located on the north side of the west of the city, which was the military garrison before Wang Sirui entered Beijing for the second time. Pen ~ fun ~ pavilion www.biquge.info

Although it is a little simple, it can still be barely inhabited by repairs, and most of the people who live here are either military or workers.

Those engineers in the real sense, Wang Sirui is also reluctant to let them live here, the engineers live in a brand new house, although it is far less luxurious than the houses in the capital, but compared to the other houses in this camp, their treatment is obviously much better.

Here, it seems to have become Wang Sirui's secret base, and it is also the most important one.

On the surface, this is just an ammunition manufacturing factory, and all the ammunition of the entire Han army will be produced here, and then sent to the troops in boxes.

Originally, there were only two production lines here, and the annual output of bullets was only about 7 million.

However, after a year of development, the scale of this place has been expanded several times, and with the improvement of technology, this ammunition factory can produce at least 30 million bullets of all kinds a year.

However, this still cannot meet the future needs of the Han army.

Some mechanical engineers and trainees, as well as technicians recruited from American equipment factories, are tasked with studying these machines and equipment every day.

They have retrofitted all of their equipment to enable them to increase their annual production from 25 million to 30 million.

After that, these people began to study every part of these devices, yes, they were to copy them, and they made their own ammunition production lines.

And on the easternmost side of the camp, it was more heavily guarded, and even the engineers inside the ammunition factory didn't know what was going on there.

All they knew was that no one was allowed to approach the area, otherwise the consequences would be beyond their reach.

This is the fourth time that Wang Sirui has come to inspect in the past three months, in fact, it cannot be said to be an inspection, but Wang Sirui attaches great importance to some research here, and once there is some new progress, he can't help but come to watch it in order to put forward new opinions.

And the last time I came here, it was just the day before Wang Sirui left for Henan, and the secret weapon studied here at that time had entered the last step, if it wasn't for Wang Sirui's excellence, in fact, half a month ago, that kind of secret weapon had been able to be mass-produced.

And this time, as soon as Wang Sirui returned to the capital, he received a report from his subordinates that the secret weapon had been successfully developed.

Although the effect is still not ideal, at least it is better than nothing.

So, Wang Sirui had just come back with his front foot, and his back foot secretly came to this nominal ammunition factory.

In fact, the ammunition factory is divided into four areas, one of which is the ammunition production area, which includes a dormitory area and an equipment research area.

The other three areas are on the east side of the camp, and because the three areas are together, most people mistakenly think that there are only two areas here.

This area on the east side is actually two areas for the research and production of artillery and one for the research and production of machine guns.

However, due to technical problems, there has been no production here, and only about 50 researchers are doing research here.

And now, their first product has finally been successfully researched. Although in their opinion, this is perfect, but it has never been able to satisfy Wang Sirui.

"Commander, according to your request, we have modified the parameters of this mortar, and at the moment it has basically met your requirements." He Shanhe pointed to the strange-looking mortar placed on the ground and forcibly suppressed the tiredness on his face and said.

He Shanhe was originally studying in Germany to study mechanical manufacturing, but later Wang Sirui was secretly inserted into the Krupp factory, and because of the transaction with Krupp, He Shanhe was also able to get in touch with some 'secret' technology there, half a year ago, after the expiration of the internship, He Shanhe resolutely returned to China, and came to this secret military base, with dozens of other scientific researchers to study new weapons.

"Have you tried it? The result? Wang Sirui was also faintly excited in his heart.

Mortars are really a good thing for troops, especially now, in the current situation of insufficient artillery firepower, mortars can make up for the shortcomings caused by artillery and provide fire support for front-line soldiers.

"A round of tests has been carried out in secret, and five mortars have been spent, and the effect is still very ideal.

The maximum firing range is 900 meters, the minimum firing range is 200 meters, and the muzzle velocity is about 100 meters per second.

With a maximum rate of fire of 25 shells per minute, a gun body length of 650 mm, and a total weight of 15 kilograms, a soldier can carry it all over the world.

In addition, due to the quality of the process and steel, the service life of the barrel of this mortar is only fifteen seconds, that is, a barrel can shoot 2,307 shells under the premise of ensuring accuracy.

If you continue to use it in the future, it will not only fail to guarantee the accuracy of shooting, but may also threaten the safety of soldiers.

At about 2500 shells, there will be serious deviations in the trajectory, which can reach more than thirty meters, or even more.

Therefore, the suggestion of our scientific researchers is that each mortar can only shoot a maximum of 2,400 shells, and when there are 2,300 shells, we should pay more attention, and if possible, we hope that each gun will only fire 2,200 shells and be scrapped immediately. He Shanhe introduced.

The service life of the barrel is only fifteen seconds, which is quite a good time, of course, the increase in the life of the barrel mainly depends on the effect of the rate of fire of the shell.

And the muzzle velocity of this mortar is only about 100 meters per second, according to these data to convert, that is, the time that a shell stays in the barrel is only 153.84 a second, that is, one second can hit 153 nearly 154 shells.

Don't think it's a continuous fire, the formula is that no matter if you use a year or two years to shoot all 2,307 shells, the total time spent in the barrel of those 2,307 shells is fifteen seconds.

If the muzzle velocity of the shell increases by 10 meters per second, then theoretically 169 shells can be fired per second, but the increase in muzzle velocity will lead to an increase in the frictional pressure inside the barrel, resulting in a decrease in the service life of the barrel.

That is to say, with the same artillery material, if the muzzle velocity of the shot is increased, then this mortar is estimated to be scrapped with 2,000 shells.

The faster the speed, the greater the friction, the greater the pressure in the chamber, and the more severe the wear.

"How's the yield?" Wang Sirui continued to ask, the first mortar was designed like this, which is actually very good, although there is no way to compare with the mortars of later generations.

"Ideally, the monthly output is about 100 doors, but now because we don't have skilled workers, it is difficult to guarantee the monthly output." He Shanhe said.

Although he is also in a hurry, this kind of thing cannot be rushed.

The mortar is a kind of smoothbore gun, so there is no need for rifling inside the barrel, which greatly reduces the difficulty of production and reduces the scrap rate of the barrel.

And what is the most important thing about mortars? Of course, it is the barrel, in fact, the most important part of all artillery is the barrel.

After other artillery pieces are scrapped, they can still be replaced with a barrel and continue to be used as new guns, but mortars are different and can be scrapped directly.

Therefore, with a monthly output of 100 doors, with their current personnel and equipment, they simply can't do it. But with such a production method as the assembly line, the output has almost tripled, and if all of them are skilled workers, there is no problem with a monthly output of 100 doors.

"In terms of personnel, you can choose at will, solve this problem as soon as possible, and after three months, the output must reach 100 doors per month." Wang Sirui ordered.

Large-caliber artillery can't be built for a while, and mortars are the only artillery that Wang Sirui can expect at present.

Of course, what He Shanhe didn't know was that what he said about a monthly output of 100 doors was only the production line in this base, in fact, this production line was used for their scientific research.

In the industrial zone outside the capital, there are two identical production lines, and according to He Shanhe, once those two production lines are started, the monthly output will reach 200 doors.

Although the number is not large, it is still 2,400 mortars in a year, and it is enough to equip the Han army with mortars.

"Yes, guaranteed to complete the mission." He Shanhe was a little depressed, but on the surface, he still made a loud promise to Wang Sirui.

The production of mortars is not something that just anyone can do. As everyone knows, when the bullets were made in the front, those big men embarrassed a group of technicians.

That's a group of masters you have to teach by hand, and everyone can only do one process, although Wang Sirui is so requested, but those people are too brainless, their thoughts are not active at all, and most of them don't know how to read, and they can't even understand the marks on the machine.

But what can He Shanhe do? He is just an ordinary scientific researcher, and the main designer of this mortar is not him, he is only involved.

Besides, He Shanhe also wants the army to become strong as soon as possible, so that when they go abroad, they don't have to suffer that kind of bird spirit anymore.

Immediately afterwards, Wang Sirui went to the artillery scientific research side again, and found that a group of people were still muttering something around a cannon barrel, so he didn't bother them, and went straight to the machine gun scientific research.

There was a replica Maxim heavy machine gun, and there were a lot of parts on the ground, but if you looked closely, you could still see the difference.

ps: Khan, forgot to update, sin, sin.

Thank you for the support of the army in 2016 these days, and thank you for the monthly pass support of Wallock who does not wear a mask! Thank you very much, by the way, can I ask for a recommendation vote...... How pitiful! (To be continued.) )
