Chapter 1129 Suggestions for improving grenade

  Seeing Qu Mao took out a pen and paper, Kong Ming immediately got into the mood, took out a pen and paper, and sat down opposite Qu Mao, obviously Qu Mao was going to start talking about the improvement technology of the grenade.

Seeing Kong Ming like this, Qu Mao rolled his eyes, and said impatiently, "Give me a dinner first. I got your long-distance communication in the morning and immediately boarded a warship. I ate a navy meal on the way." , I am hungry now.

  600 kilometers, I arrived in less than eight hours. Yidao is 300 kilometers away from Yancheng Port, and it usually takes about five hours now, which shows how anxious I am. "

  Kong Ming said with a smile: "It's all small things, but even though this is the Firearms Research Institute, only the army's military meals can be eaten."

   Soon, the dinner was served, and Qu Mao said while eating: "The problem of large size is not conducive to projection. It must be improved. The size of the grenade can only be the size of a fist."

Kong Ming smiled and said, "My lord, the current technology for firing clay pots is not yet capable of firing pottery the size of a fist. After all, the thickness of pottery is about one centimeter. For a pottery the size of a fist, the gunpowder filled in the internal space is not enough. Pop open the pottery casing.

  Porcelain can be used to explode, but the subordinates have tested it with porcelain before, and the fragmentation effect of porcelain is not as good as that of pottery. "

   Qu Mao shook his head and said, "The shell of the grenade needs to be made of cast iron. After dinner, I will tell you how to use the structure to realize the explosion of the cast iron shell with gunpowder."

  After Qu Mao had finished his dinner, Kong Ming immediately cleaned up the table, put the paper and pen that Qu Mao took out before Qu Mao, and himself took out a paper and pen and sat down on the opposite side of Qu Mao.

Qu Mao picked up the pen, and while writing and drawing on the paper, he said, "Kong Ming, the grenade you have made so crudely, you might as well make it a bigger pottery, and change the trigger device so that when you step on it, it will ignite the internal sparks." The form of gunpowder inside the pottery.

You see, increase it a bit. On the United Islands, the sparks from the gun barrel I hung with a knife can be used as a reference for your ignition device. The core is that the landmines are buried on the ground. On the road that the enemy must pass by, as long as the enemy steps on the landmines It will explode and kill them.

   Of course, pottery fragments alone must have limited lethality. If pottery shells are to be used, then some irregular iron pieces, iron beads, etc. should be placed inside the gunpowder filling to increase lethality.

  The core is the trigger technology, you can refer to the firing technology of the flintlock gun you are getting now. "

  Kong Ming watched Qu Mao draw pictures on the paper, nodded thoughtfully, and kept recording in his notebook with the pen and paper in his hand.

Qu Mao continued: "Just now I said that the mines are filled with iron sheets or balls. If the trigger technology is really difficult to solve, then you can also consider using a rope to pull the detonation method from a distance. It is nothing more than a good way to ambush. thing…"

Kong Ming nodded, and before Qu Mao finished drawing the white paper, he took the paper from Qu Mao's pen, folded it a few times and stuffed it into his backpack, saying: "Thank you for your guidance, my subordinates have already understood the technique of landmines. The core is still to be tested. I believe that the subordinates will produce the finished mines for you in a few days. Don't worry.

   But the subordinates are more concerned about the improvement of the grenade. Sir, have you not mentioned the improvement of the grenade? How to make the explosion of gunpowder explode the casing of the cast iron grenade? "

   Qu Mao glared at Kong Ming and said, "Kong Ming, let me stress again, the grenade only needs to be the size of a fist.

We use cast iron technology to make the shell of the grenade, but there is a little change in the appearance design. You can see in the picture that we have to make regular bumps on the surface of the grenade, alternating vertically and horizontally, so that when the internal gunpowder explodes, it will be compared with the shell of the grenade. The thin part exploded, and the cast iron casing was cut into pieces by the explosion, causing damage to surrounding enemies..."

As Qu Mao explained and drew a pineapple-like shape on the paper, Kong Ming looked at the picture drawn by Qu Mao and suddenly realized: "My lord, you mean to make the shell of the grenade into a cast iron shell, just like a pineapple. Usually, during the casting process, we have ensured that there are inconsistent thicknesses on the shell of the grenade, so that the gunpowder can explode after being loaded into it."

   Qu Mao nodded, and said: "The principle is probably like this. To what extent you want to master it, you need to experiment a few more times. It must be able to be transported safely and have enough lethality after the explosion.

  That's all I know, you know, Kong Ming. "

  Kong Ming nodded, recorded a few words in his notebook, and said, "Well, my lord, this subordinate will start researching immediately after turning around."

  Qu Mao continued: "Furthermore, the detonation mechanism must be adjusted, and it is absolutely impossible to pull out the fuse.

My idea is: there is a safety catch. After the safety catch is pulled, as long as the trigger is still held in the hand, it will not explode. After throwing it out, the trigger will automatically bounce in mid-air, and it will take 3 to 5 seconds after the trigger is released. It will explode in time.

   This is enough for our fighters to throw the grenade, and the grenade can explode once it enters the enemy group. "

  Kong Ming said with a bitter face: "My lord, the ignition speed of the Thunder Mercury technology is too fast and completely uncontrollable.

  After the subordinates conducted several experiments, they finally realized why you, my lord, did not allow the subordinates to carry out the experiments in person. Because the danger was too high, two researchers who conducted the experiments were killed and three were disabled.

  Three disabled researchers, one of them has been forced to retire and go home, and the other two have all their fingers blown up, so they can only be turned into professors at the Firearms University. "

   Qu Maodao: "Researchers who were killed and disabled in battle must be generously compensated.

  Look, the trigger diagram is here. After the grenade is thrown, the circlip will automatically pop open during the flight, triggering the ignition device inside, and then an explosion will occur.

   You try a few more times, I believe it will be successful. "

  Kong Ming nodded thoughtfully, seeing Qu Mao put the pen aside, Kong Ming immediately put away all the papers that Qu Mao drew, folded them and stuffed them into his backpack as before.

   Qu Mao continued: "Kong Ming, future soldiers of the Firearms Army, I hope that each soldier will be distributed with 4 grenades, so that the long-range and short-range kills are all ready."

  Kong Ming said: "Yes, my lord.

  My lord has given my subordinates a lot of inspiration tonight, and the subordinates still need time to digest, absorb and verify it through experiments.

  We still have a long way to go in the research and development of firearms. We can't completely rely on your teaching every time. Our firearms research institute must have independent research capabilities.

  Now the battle against the Anti-Yizhen Alliance has begun, and you have nothing to do in a short time, my lord. Why don't you just stay in Midway Twin Islands for a while. "

   Qu Mao nodded, and said: "Yes, they are all here, so naturally they will hang around for a few days."
