The shells used in this experiment are naturally different from those used in actual combat. If it were not for the convenience of seeing the bullet points, the arsenal would not be willing to put black gunpowder in it.

However, isn’t it necessary to experiment with new shell fuses? That’s all!

The most dangerous thing here is the experimenter! For example, the previous experimenter No. 1, just broke his arm, and some of them were blown away. Especially when experimenting with newly designed weapons that have not been tested on the battlefield.

Fortunately, the weapons selected by Hu Yizhou were baptized by war in the original time and space, and were passed through repeated experimental tests by many people. Some countries have been used for decades.

For example, our flower grower imitated the 55-type model, and also participated in the battle between Asan and the White-Eyed Wolf, and achieved good results!

Even at the other Mao Xiong's house, it was the main regiment supporting artillery, with a large amount of equipment in its own team, and it was used for 50 years. During World War II, the soldiers in Hanscao's family suffered a lot of losses from this mortar.

Designing a weapon is not just about thinking about it out of thin air, drawing drawings and then creating it. It requires the designer's genius ideas and repeated experimental demonstrations, and it takes countless experiments to finally be finalized.

Of course, if you don’t have to do the bolt-action rifles, no matter how they change, it will be like that. There is a British 77 who can shoot faster.

Fortunately, Hu Yizhou does not need to make repeated arguments, experiments with various materials, and does not require battlefield inspection. He just draws the finished drawings of others and then creates them accordingly.

In the test site, as the first experimental bomb was shot out, the second and third were shot out in turn...

"Boom boom boom..." A stream of black smoke rose up at the bounce point in front of it, and the flames burned the grass and trees on the barren mountain to brown.

"Captain, our experiment was considered successful, right?" Director Shi asked loudly.

"Switch to another cannon and continue the experiment!" Hu Yizhou shouted.

Soon, the experimenters replaced another mortar, and another series of explosions rang out, and the experiment was finally successful!

Then next, the experiment of shells, which is the most dangerous!

The experimenters also knew the danger at this time, so they stopped for a while before starting to operate the mortar.

Take out the shell from the box and load it with a fuse. Experimental No. 1 carefully put the shell into the muzzle.

"Bang...chub...bang..."

The test was successful, and the power of the 120mm mortar shell was revealed. Most of the small hill was covered with fire. The vegetation that had been roasted before was brought to the fire.

Fortunately, the ones who choose the barren mountains with few trees, there are no continuous forests around them, and even large areas of isolation belts have been cleared. Otherwise, it will be troublesome if a forest fire is caused!

Even if it rains hard, you must always be vigilant in forest fire prevention!

Hu Yizhou was very clear about the drawings and materials he remembered. As long as there was no big problem with the material application and manufacturing tolerances, the weapons he made would basically be fine.

This is also the confidence that he dares to inquire about the arsenal. Otherwise, he will honestly create grenades and wait for the end of the War of Resistance...

Now it seems that the materials in the arsenal are fine, there is no problem after the shell shell is changed to ductile iron, and there is no problem in the manufacturing of the fuse, so the results of the experiment are naturally satisfactory!

With the rumbling explosion, a total of 20 120mm mortar shells were shot by two cannons. This is a serious anti-destructive blasting grenade. Even if a shell is ductile iron, it is too expensive and cannot be wasted.

What happened next was to measure the ballistic data under various charges, formulate a ballistic table, and hand it over to the artillery troops.

The planned output of the 120mm mortar is 122.

Of course, these 12 doors do not include the two doors that are currently being tested. This is just the test model. There are only three main parts of the lonely mortar structure - the gun barrel, the seat sheet and the bracket, and at most a scope is added.

But this is not possible. It also requires some structures suitable for hauling or traction, and structures such as tires are added for easy pulling.

When you get to this weight of mortar, you basically say goodbye to walk by yourself. It is not possible to rely on manpower to carry it and run!

Of course, there is nothing to do under extreme conditions. It is necessary to use someone to carry it.

Therefore, Hu Yizhou prepared 12 120mm mortars for the security team that Xiang Dongfang said, which was purely a fool! With such a large transportation capacity of Mao Xiong's family, a single infantry regiment was only equipped with 4 doors.

Even if the security regiment can equip 8 120 mortars, it is only if Hu Yizhou spares no effort to increase the number of artillery troops.

12 mortars and 4 were given to the military rabbits, so I had already thought about it. When the security regiment went out to fight, I only needed to bring 8 120mm mortars as regiment-affiliated long-range firepower.

The logistics pressure on this quantity and logistics has reached its limit. Even the shells cannot carry much! A shell weighs 16.6 kilograms, and the weight of a 7.62×39mm middle power rifle bullet is 16.4 grams.

In marching, when the capacity is limited, should we bring enough shells or enough bullets? This is a difficult multiple-choice question...

Of course, Hu Yizhou was not just fooling him to the east, and 12 120mm mortars still need to be equipped. For example, two can be equipped in Songjia Village on Erdaopo, or permanent fortifications can be established in Jiuzhai, and several 120mm mortars can be added as defensive artillery fire.

If you use it in Jiuzhai, then there will be no problem! It will take a long time for the young and strong to carry two shells by one person...

"Now, I announce that Jiuzhai's 120mm heavy mortar was successfully manufactured!" Seeing that the test shooting was completed, Hu Yizhou announced the news, which attracted everyone's applause.

From then on, Jiuzhai Arsenal has another product! Although this product is not planned to be mass-produced for the time being, it is also a symbol of Jiuzhai Arsenal! Because, domestic heavy mortars are not as large as those of this type. Its power is even stronger than the imitation mountain cannons of the Jinsui Army.

As for selling this mortar technology to the Jinsui Army? Hu Yizhou never thought about this problem. After all, we always need to have some killer weapons.

"Manager Shi, this 120mm mortar will be produced first 16 units! 8 of these 12 doors are made according to the full set of drawings I gave you, so that the traction is convenient and firm!"

"As for the remaining 8, just three pieces of naked cannons are enough! As for shells, the killer and blasting grenades must ensure the two bases of the 8 cannons, and the remaining one cannon is enough!"

"In addition, do not stop the production lines of the three types of shells, and be prepared to expand production at any time!"

"yes!"
Chapter completed!
