The pai-strike bomb is the most technical content of the entire mortar and the key to the completion of the mortar task. A total of 12 engineers and 21 fitters were accepted. After this study, the drawing given by Yang Yuanzhao was overturned in just one week. The ordinary striker model was considered to be unsolvable. After research, the engineer decided to make certain modifications based on the ordinary mortar. The bottom will be equipped with a fixed device, and the bottom fire will be added in one excitation. The shells and the bottom fire need to be added.

This is actually the prototype of a mortar. In 1904, during the Russo-Japanese War, Russia had already implemented the trench tactics against Japan, but no one noticed it.

To a certain extent, this method has achieved one-time molding from scratch, which is slightly worse for Baotou. Such a solution has suddenly moved the mortar from theory to practice.

After several stages and several studies, many scientists have summarized in addition to a lot of data, and gradually began to consider how to fix the gunpowder pack on the pai strike bomb. In this way, the firing speed of the mortar will be improved again on the previous basis.

In a sense, speed is the key to a small cannon. Even if a gunpowder pack is installed, the speed of the mortar is much faster than that of an ordinary cannon, but its power is slightly smaller.

Yang Yuanzhao spent almost all day here. If he had to tell him, it would be really difficult for him to have theoretical questions about mortars. He had only a little understanding of the cannons, but he drew a general schematic diagram. It is still OK. Later generations looked at those military pictures. He even saw similar pictures of mortars and the general appearance of the shells in the QQ picture animation. He still knew the general structure. Compared with ordinary shells, the belly is a bit large, the tail is shrinking, and even some tail wings are added.

The addition of the tail wing is definitely the finishing touch. In itself, referring to the previous mortar cannon, the flight trajectory of the shells is simply uncontrollable, the direction of gunpowder alignment is different, and the position changes greatly. This is probably that although Russia uses mortars to deal with the Japanese army, neither Japan nor Russia have noticed the key to the epoch-making infantry weapon of mortars.

With the tail wing, the medicine bag is barely fixed in front of the tail wing, leaving a passage above the shell. The striker at the bottom of the mortar can impact the shell, and then ignite the gunpowder bag. The gunpowder burns to push the shell and erupts forward quickly.

The shell falls into the mortar. Before the tail wing lands, it first hits the striker. The strong gunpowder will be excited in an instant, erupt backward, and then push the shell forward to impact. How safe is it and how much can it have the greatest strength? This requires a series of experiments, and the shell fuse, at the beginning, uses the most reliable and easiest impact lead, rather than the unreliable delay lead.

After a week of continuous development, a relatively mature plan was finally agreed. After drawing accurate drawings, it handed it over to the machining workshop. After a day, the machining workshop took out an experimental product and several mortars made.

Because it is a test product and is temporarily produced, whether it is a barely made mortar or a shell that looks strange, he followed the same strange mortar and took it to the artillery test site and tried it.

Wang Jinming and several artillery commanders were also invited to watch. Wang Jinming has been back for a few days and is planning to suppress bandits. To be honest, suppressing bandits is not easy, not as simple as Yang Yuanzhao thought. You should know that the northwest is also vast and sparsely populated. Because it is close to Mongolia, it is easier to obtain horses. In addition, this is an important business road. The horse bandits active in this area are almost like a cow. Recently, because the year is not good, there are not a 5,000 bandits passing through Henan, Shanxi, and even Shaanxi. There are not a 5,000 bandits, some of whom have no fixed place, and some gather in the mountains to guard them. If you don’t understand the information, you will go rashly. I am afraid that the 3,000 new army will not even have a dregs left. Even the Yellow River Patrol Battalion is really encountered in the wild with bandits. It is not easy to defeat them, and it is even more impossible to wipe out them completely. Like the Red Thief, it must not be done again.

"Tao Wang, what did we do? I didn't see any cannons!" The person who spoke was Li Tie, the leader of the artillery team. He was from Hebei and had dealt with Wang Jinming before. Later, Feng Yuxiang went to the northeast. He searched from many places and invited him from the fourth town. At that time, he was just a gunner, but he had strength, but he did not become an official. Feng Yuxiang was given the title of the rank of the lieutenant.

I have to say that Feng Yuxiang has a good vision, Li Tie has strong skills, and with the help of a large number of shells, his artillery skills are even stronger. The most important thing is that his management ability is outstanding. Feng Ying was able to train more than 100 gunners, which has a lot to do with him.

"I heard that it is a new gun, a new product of the laboratory, let's take a look!" Wang Jinming said, but he didn't agree with it. After all, China has not made guns for many years. The Jiangnan Machinery Bureau imitated the 150 and 180 naval guns, which is completely a waste. Even Beiyang is unwilling to use them. It has a short lifespan and is not easy to control. It is completely different from foreign countries.

"Here you!" The sharp-eyed orderly saw a tractor moving forward in the distance from Baotou, followed by several carriages. In less than 5 minutes, the vehicles stopped. Yang Yuanzhao first greeted Wang Jinming, and then everyone's eyes fell on the strange tubes.

The pipes seem to be seamless steel pipes imported from Citi. They are welded together by electric welding. They seem to be welders of first-class masters. There are not many welding points on the surface, strange pipes, no running bolts, no aiming devices, just one pipe has a bracket, and a square base at the bottom.

Li Tie couldn't help but mutter in his heart: "Master Yang's mind is flooded, and it looks like a cannon is a cannon. This is not a child playing house!"

Although he thought so in his heart, Li Tie didn't say much. Yang Yuanzhao's status in Baotou. Li Tie knew very well that he could say that whether it was the militia and the Yellow River Patrol Battalion, they all relied on Yang Yuanzhao's breath to live.

After carefully setting the mortar right, several experimental personnel carefully took out a few strange shells, which looked like ordinary shells, but they were completely different. The head was pointed, and there was a big one in front. After tightening the back, there were several things at the bottom that looked like arrow feathers.

Although it was not the first time to test, a new product needed a lot of preparations. There were several hidden pits around and protective cover made of sandbags. Yang Yuanzhao and others left the test site and went to the Yongguo bunker next to them. Anyway, there were telescopes that could clearly see everything here, leaving only two experimenters, one responsible for holding the mortar and the other responsible for firing shells. Of course, this shell is practical, and a small amount of gunpowder and earth are filled with the cannon body. The power of the explosion is not very strong.

When he was in a correct position and aimed at the front, the experimenter was a little nervous. However, he stopped his hand and placed it in a void. In the count of another person, he lowered the shell. With a clear sound, a fog came out of the gun, and the shell flew forward steadily. At the next moment, it fell one hundred meters away, and another sound broke out.

"This!" Li Tie widened his eyes. Although the cannon was not far away, only about one hundred meters, it looked like a child's play, and a cannon that looked like a child's play was really a cannon.

The researchers have already stepped forward and started to calculate data. Similar experiments and data collection have been in progress since the project was established. Wang Jinming and Li Tie are more concerned about this strange cannon. Li Tie even asked Yang Yuanzhao for his consent and went forward to try the weight. He chose light steel pipes, plus the base and bracket, less than 7 kilograms. One hand can easily lift it, not much heavier than a rifle.

Li Tie's face immediately changed. He went to Wang Jinming and told Wang Jinming about the weight he estimated. Wang Jinming also stepped forward and experienced it himself. There was no calm expression on his face, and instead he was solemn.

What does a cannon that can be carried by a single soldier mean? Whether it is Maxim or 75 cannons, they are all firepower of the town, with strong strength, but still moving. For mountain combat and bandit suppression, they are almost just a decoration. Similar to the Red Trouble, the time when they were in fixed places, fixed battlefields, and ambushing, after all, are a few. For horse bandits, they are more likely to encounter battles and rely on, that is, rifles. Maxim is not reliable. No one will give you time to place Maxim, but this cannon seems to give him new ideas.

"Yuan Zhao, what is this gun called and what is his technical indicators!" Wang Jinming said solemnly to Yang Yuanzhao.

"This!" Yang Yuanzhao smiled slightly and asked the experimenter: "What are the indicators of Experimental 17 mortars!"

"12 rounds per minute, the gun weighs 7 kilograms, and the total weight will not exceed 12 kilograms. The shell weighs 2.5 kilograms and can charge 0.35 kilograms. The maximum range in the experiment is 500 meters!"

The charge is not much, 0.35 kilograms, which is more than 7 taels, but this is a yellow bomb. The 7 taels of yellow bomb may not be much worse than the old-fashioned shells, 12 rounds per minute. This speed is far beyond the ordinary 75 heavy artillery, and the range of 500 meters is closer. However, as infantry support firepower, it is enough, at least in the attacking battle, it is enough to knock out the firepower points in front. The most important thing is that it is light enough, with a weight of 12 kilograms, plus 24 rounds of artillery shells, two to three well-trained soldiers can carry them and march and turn with the troops. The effect here is very great.

"Yuanzhao, our patrol battalion and militia must be equipped with it!"

"It's not mature yet and needs improvement. Let's do it. At most half a month. After it is stable and established, you will definitely give it the first batch of equipment!"

From the test site, Yang Yuanzhao's face was full of smiles. Not only did it solve the problem of mortars, the Baotou New Army will have a close-range support firepower. Another reason is that the mission has finally taken a big step forward. The sub-item of the artillery has increased its monthly output to 3 units. Obviously, the mortars are also cannons recognized by the mission. (To be continued, please search Piaotianwen, the novel is better, updated and faster!
