"It's such an inconspicuous little thing, it's even more useful than a grenade!"

Qin Chuan's statement surprised Zhou Dajing again. Pen? Interesting? Pavilion wWw. ｂiquge。 ｉｎfo

Although in view of what Qin Chuan had been doing, Zhou Dajing couldn't help but believe his words, but Zhou Dajing was still very skeptical in his heart about how useful such a small piece of iron pipe could be.

Qin Chuan saw Zhou Dajing's thoughts, and didn't say much, bent down and reached out to pick up the small piece of steel pipe that looked strangely and still had a mechanism, took it in his hand and carefully checked it for a long time, and even pulled the trigger-shaped switch with his hand, and then pulled the exposed cowhide belt with one hand, only to hear a crisp sound, "click", and the trigger-like thing rushed forward to the top along the small groove on the thin steel pipe.

Zhou Da pondered that there should be a small spring behind this trigger-shaped thing to make power.

After fiddling with the trigger, Qin Chuan used the light to observe the situation inside the small section of steel pipe from the front end, and even stretched out his finger to touch it inside, and then handed over this inconspicuous and strange thing to Lu Dezhang.

"Lao Lu, you can introduce us to this treasure with the price of cabbage."

"Good!"

Lu Dezhang took that small piece of strange thing in his hand and began to introduce it. It's just that when it is said to be an introduction, it is actually half of introducing the usefulness of this strange thing to Zhou Dajing, and half of it is reporting to Qin Chuan.

"This thing, we developed it according to the drawings designed by the commander, and the commander gave him a name, called a grenadier."

"Grenadier?"

Zhou Dajing pointed to the cannonball-like thing in another box and asked Lu Dezhang: "You mean, this thing is the one that fired these small cannonballs?" ”

"Yes."

Lu Dezhang nodded affirmatively: "That's what fired these small shells." Because it is not as cumbersome and complex as ordinary artillery, it can be operated by one person, so we also call this thing a hand cannon in our repair shop. However, the name grenadier is apt, because when fired, the ammunition in it flies out along a parabola. ”

"Specifically, the parameters of our grenadier are: caliber 50mm, barrel length 260mm, full gun weight 2.8 kg, barrel foot length 170mm, barrel foot weight 1.2 kg, foot thickness 70mm."

Seeing that Zhou Dajing was still going to ask questions, Lu Dezhang waved his hand and motioned for Zhou Dajing to listen to him.

"The grenadier is between a grenade and an artillery, and this is mainly compared in two ways. The first is range. As you can see, our grenades are estimated to be thrown at a maximum distance of 180 meters, and the range of 75mm guns is now four or five thousand meters, and there is a large gap in firepower between these two ranges. In particular, according to the commander, the distance directly involved in the battle during the battle is mainly within 500 meters, and at this distance the enemy can be killed and injured basically by visual sight. If a single soldier can operate a weapon to directly kill the enemy, then you can get the maximum result in the shortest time. ”

"Our grenadier has a range of 300 meters."

"Second, of course, it's power. The grenade ammunition fired by the grenadier is more than twice that of our grenades, and the power is naturally much greater than that of grenades. However, compared to the power of the 75mm mountain gun, it is much worse. ”

Lu Dezhang looked at Qin Chuan with some regret and said: "According to the commander's requirements, our grenadier is rifled, but the commander requires that in order to increase the airtightness in the grenadier when firing, a copper hoop should be added to the ammunition." Not to mention that the amount of copper produced in the Qing Dynasty is very small, we want copper again, and it is easy to say that we need to produce a small amount of ammunition, but it is a little difficult to produce a large number of ammunition. Therefore, we did not install that copper hoop on this batch of trial ammunition. It is precisely because there is no copper hoop that the air closure is poor when launched, and the range is only 300 meters. ”

Seeing that Qin Chuan didn't speak, Lu Dezhang hurriedly added: "However, a few of us have also pondered, if it is not impossible to reach the distance of five hundred meters required by the commander, we can make the launch canister longer, and it will also have an effect on the increase in range." In addition, if you don't add copper tape to the ammunition, there is no need for our grenadier to have rifling, which can also save costs. ”

Seeing Lu Dezhang waiting for him to make a statement, Qin Chuan shook his head slightly and didn't speak, just quietly listened to Lu Dezhang.

"The killing radius of ammunition has not been tested for the time being, and it is estimated that it will be similar to our grenades。。。。。。"

In terms of power alone, the effectiveness of the grenadier is much lower than that of the 60mm mortar, and the technical principles and process requirements of the mortar are not very high, and now the technical strength of the Tianjin Machinery Bureau is enough to complete it. It's just that Qin Chuan is still afraid of the strong technical background and strong industrial strength of the great powers and even Japan, and he doesn't want to show the mortar to the great powers too early, especially not to let the Japanese and Russians master the mortar weapon too early.

Therefore, Qin Chuan had no choice but to settle for the next best thing and take out the grenadier canister with less lethal effect first.

The grenadiers were mainly equipped with the Japanese and German armies in World War II, and Qin Chuan really had never heard of other countries' armies being equipped with grenadiers, if there were, it was only a large number of imitations of equipment by the Chinese army.

The caliber of the grenadier is basically below 50mm, so it is lighter in weight and can be carried by a single soldier, and the grenadier can follow the charge of the troops and provide medium-distance fire support at any time, which is also a significant advantage of it.

Since the charge of the propellant is fixed, the firing distance can be determined by adjusting the angle of the grenadier to aim at the target, so the general grenadier is not equipped with a sight. Also because there are no sights, only experienced grenadiers with long-term training can accurately hit the target.

As for the range of this grenadier mentioned by Lu Dezhang, lengthening the barrel body is a solution, and the Eighth Route Army also adopted this method decades later when it was unable to process rifling and lacked copper. However, this adds weight and is not conducive to individual carrying.

Qin Chuan thought for a while and said to Lu Dezhang: "The range of 300m is closer, but it is still necessary to increase the range." I mean don't make a fuss about the length of the barrel, or add copper cartridges to the ammunition. In order to ensure sufficient supply, in the long run, we will also set up foreign trade institutions in Chile, a large copper-producing country, and buy copper and saltpeter from Chile in large quantities. ”

"In addition, you also need to do more experiments on the ammunition to ensure that the small-caliber ammunition of the current grenadier canister achieves the best lethal effect."

After Qin Chuan made some detailed requirements for Lu Dezhang's grenadiers, he asked Lu Dezhang to start the demonstration launch.

Because the grenadier canister has a long range, and it is not easy to grasp the accuracy for the time being, Lu Dezhang took out all the ammunition for testing the range and training, except that this kind of ammunition is not loaded with explosive explosives, it is exactly the same as live ammunition in terms of shape, size, weight and propellant charge.

The grenadier was operated by Bian Changsheng, only Bian Changsheng squatted on the ground, erected the grenadier diagonally with one hand, and pulled the firing device with the other hand and took a piece of ammunition handed over by Lu Dezhang to load, Qin Chuan hurriedly shouted to Bian Changsheng and signaled that he wanted to come in person.

Qin Chuan took the grenadier, knelt on one knee, held the barrel with his left hand, and took a piece of ammunition from the mouth of the barrel with his right hand, and then Qin Chuan stretched out his right arm and held it flat in front of him, cocked his thumb and aimed at it a little, and then his left hand began to adjust the inclination angle of the grenadier, and then withdrew his right hand and quickly pulled the firing belt.

Listening to a low muffled sound of "bang", the ammunition that Qin Chuan loaded in had already flown out in an arc, but because of the long distance, Zhou Dajing and Lu Dezhang couldn't see where the ammunition landed.

There is no need to command, Bian Changsheng and Cha Lianbiao have already run over.

Qin Chuan put the grenadier on the ground, clapped his hands and stood up.

"Lao Lu, the posture of the grenadier launch should be like ours, and this posture should be required as the launch standard. Other than that...... ”

Qin Chuan thought for a moment and said to Zhou Dajing: "Go back and take out a squad of personnel from the repair institute and use them as weapon demonstrations." Remember, the personnel who are deployed should be smarter. ”

Zhou Dajing nodded and didn't wait to speak, but Lu Dezhang asked suspiciously: "Commander, have you seen our grenadier in the past two days?" ”

Qin Chuan didn't understand what Lu Dezhang meant, shook his head and said, "I haven't seen it." ”

Lu Dezhang was even more strange: "Is it really the first time the commander has seen our grenadier? ”

At this time, Qin Chuan had already understood what Lu Dezhang meant, and he couldn't help but panic a little, but then he came up with a way.

Qin Chuan smiled indifferently and said, "Old Lu, are you saying that since it is the first time I have seen this grenadier, why do I feel very proficient, right?" ”

Lu Dezhang nodded, Zhou Dajing also found this problem at this time, and also looked at Qin Chuan a little strangely.

"It's very simple, Dajing, you should know, I taught Qiu Qinghe and their artillery brigade how to use the method of visual aiming to fire without a scope."

Because the last time he was in Beiyang, Qin Chuan's brave performance made the people of the artillery brigade extremely admired, and Qiu Qinghe even pestered Qin Chuan to ask Qin Chuan to teach his artillerymen how to operate artillery, and Qin Chuan taught the methods of visual aiming to those young men in the artillery brigade by the way. These are clear to Zhou Dajing.

"To visually aim, only this position is best suited for operating a grenadier."

Qin Chuan's explanation was reasonable, and Lu Dezhang and Zhou Dajing thought about it, so they didn't ask any more.

Zhou Dajing let out a long breath, and then couldn't hide his excitement and said to Qin Chuan: "Commander, apart from the bulky artillery, these two treasures of grenadiers and grenades should be regarded as the most powerful infantry weapons in the world. ”

Qin Chuan, who was also extremely excited in his heart, was about to speak, and Lu Dezhang, who didn't want to be on the side, said: "The two new weapons of grenades and grenadiers are indeed very powerful, but if you want to say that they are the most powerful, then it is not, we have something more powerful than these two in Beiyang." ”

Lu Dezhang's words made Zhou Dajing stunned, and even Qin Chuan was a little confused.

What weapon could be more ferocious than this grenade and grenadier canister?

Moreover, it is still in Beiyang?

Qin Chuan said in his heart: "Grandma's, this is a ghost, such a powerful thing, why doesn't Lao Tzu know?" ”

"Could it be。。。。。。 And those who have crossed over like Lao Tzu? (To be continued.) )
