Release that Witch
Chapter 567: Flowering bomb!
No winter city, the suburbs of the West Wall.
The huge roar has attracted many people to climb the wall to pick up the crowd. The First Army has blocked the entrance to the hidden forest to prevent people from breaking into the test site.
Although the location is far from the city wall, with the lookout mirror, you can clearly see what happened here. It seems that I have to find a remote place as a dedicated arms test base in the future, Roland thought.
"Your Majesty, the second round of launch is ready!"
"Everyone goes into the bunker," he waved. "Recognize no one and count down."
It is now the 152mm howitzer test to study the magic stone, while Roland has not put down the improvement in thermal weapons. Now that Tefco has been destroyed, the Northland has declared its return, and the situation in the Grey Fort is very good. He has also worked hard to make a new round of improvements to the shells.
However, it must be said that the howitzer with trigger fuze is technically more difficult than the solid bullet. Anna will make four shells for testing every day. The result is three days, and no shell has exploded. Even on the second day of testing, a shell was blown out directly, and the new gun tube used for testing was smashed. Fortunately, Roland was prepared to dig a few trenches around the test site to prevent accidents, and no casualties were caused. As for the soldiers who were closest to the artillery, the eardrum was broken and Na Nava was cured in time.
"Is this thing really like you said, when you hit the enemy, it will explode?" Ai Gesha stood in the trench and couldn't help but visit. "I asked Anna, it is made up of several pieces of metal, not life." Body, how can you tell if the other party is an enemy?"
She is regarded as the most active witch in the league for weapons testing. After learning about this, even the production of the chemical plant was temporarily put aside, and she made a special trip to observe the research progress of the new shells.
"It’s not the enemy, but the enemy’s position will explode,” Roland corrected. “This is also a requirement that the howitzer must meet. If there is no insurance to ensure this, the shells may go away at any time, so Too dangerous."
Triggering insurance is the core technology of new shells and the focus of testing.
In order to avoid collisions, missed hands and caused a false explosion, he painstakingly set up a total of three insurance.
The first is that the fuze is separated from the shells for storage and transportation. Until the time of use, the fuse is shaped like a cone with a handle. It is almost the size of a fist. The tail has a thread. When installed, it can be screwed into the slot at the top of the shell. Convenience. Since the shells are loaded with double-base chemical gunpowder, it is difficult to detonate without the detonator, which fundamentally guarantees the safety of the logistics work.
Followed by inertia insurance in the fuse.
It is similar to the door lock. Under normal conditions, it is held by a hard spring. It cannot move. When the projectile is launched, the huge inertia will cause the lock cylinder to sit back, thus urging the resistance of the spring to open the latch and release the second insurance.
The principle is very simple, but it is not easy to achieve it. The first two days are basically spent on the top. If the spring is too hard, the lock core cannot sit back enough. The spring is too soft and not safe enough. The test firing situation was slowly adjusted, and a relatively reliable spring compression data was obtained after six rounds of testing.
The last insurance is the centrifugal detonator.
It is also the most technically interesting thing in the fuse. In simple terms, the detonator is embedded in a coin-sized semi-circular iron plate, which is usually placed obliquely in the center of the fuse and fixed by a spring. At this moment, the needle, the detonator, and the stimulating medicine are not in a straight line. Even if the shell falls from a high place, the striker does not touch the detonator and avoids the risk of fire. The iron plate is only movable after the second insurance card has been released from the lock.
Due to the action of the barrel of the barrel, the shrapnel will spin at a very high speed. Under the action of the centrifugal force, the inclined detonator will gradually return to the positive direction. Like the rotating gyro, the center of gravity moves closer to the central axis. This process is completed approximately two or three hundred meters after the exit, so that even if the muzzle is blocked or the branches are covered, the warhead will not explode in advance.
When the detonator is completely back, it forms a straight line with the striker and the stimulating drug. At this time, once the fuze touches the ground, the striker will be plunged into the detonator, and then the high-heat gunpowder jet is used to enter the warhead warhead. Torn the enemies around you into pieces.
The advantage of centrifugal insurance is that if the projectile is misfiring, the detonator that loses the centrifugal force will be turned back to the original position by the spring, and will become inclined again, so that the recycling work is much safer.
In addition, if the entire grenade is captured by the enemy or picked up by chance, it will be fired in the conventional way. If it cannot obtain sufficient centrifugal force, it can only be used as a solid projectile. As for the dismantling of the imitation, it is even more impossible.
"Ready to launch, count down five times!"
The observer issues a password.
The ropes that have been lengthened several times are slowly tightened, and the gunners hiding in the trenches recover the ropes a little.
"Open fire!"
As the soldiers slammed, the ground shook.
The fierce muzzle wind accompanied the roar of sweeping across the head of the scene, and Roland felt that a lot of tiny particles had rolled into his collar. Even if you block your ears, you can feel the tremors from your feet.
"Observed the drop, no explosion, repetition, no explosion."
The sound of lightning in the hands of the nightingale quickly came.
"Know it, we will pass right away." She pulled out another piece of magic stone back.
"...has it failed again?" Ai Gesha was a bit frustrated.
“Failure is normal when you are groping,” Anna said comfortably. “Once we find the right direction, we can ensure that we no longer fail in mass production.”
"That's right," Roland patted her head with approval. "And with the help of Axia and Sylvie, the progress of this research and development is already amazing."
In the afterlife, the grenade's stereotype test is not a problem with thousands of hairs. It is no different from the Arabian Nights to find the problem within two or three.
When the warhead landed, Anna first cut off the fuse with a black fire to ensure that the warhead was safe. Then the soldiers took away the waste bombs, whether it was gunpowder or metal bullets, and they could be reused. Naturally, they could not be wasted.
"Axia, it’s up to you." Roland gestured to her.
"Yes, Your Majesty," she nodded and showed her replay ability. In an instant, a phantom of a shell that was about to fall on the ground appeared in front of everyone.
Axia's magic level is still low, after only a few months of training can only support four replays, but by precisely controlling the magic, she can now freeze the replayed picture at a certain moment.
And this kind of replay is a perfect re-enactment scene. In other words, Sylvie's perspective can see that the inside of the illusion can't be touched, it is no different from the real scene.
This is why Roland solved the problem of spring strength with only eight rounds of shooting. (To be continued., your support is my biggest motivation.) 17-02-0405:29:32
