Why don't you go out first? Li Changjiang said on the side.

What is going to be done next may be dangerous, and it is useless for both of them to stay in the turret, so Li Changjiang now suggests that Qin Zhenhua go out first and leave him alone.

Hearing this, Qin Zhenhua shook his head with a smile: "Master Li, what can this be?" It's not the first time we've been gunners, this little accident, don't you know what's going on? Are you worried about being like my father? That's impossible. ”

Back then, Qin Zhenhua's father sacrificed himself in order to test the cannon, but it was very different from now, when it was to improve the power of the artillery and improve the shell, but the bore exploded, causing a martyrdom.

What now?

This kind of cannon has been tested for a long time in the Second Machine Factory, and there have been 5,000 rounds of firing of not 10,000 rounds, and all kinds of situations have been tested.

Since it's not a martyrdom, it's not the worst case, if it's blind, then let's eliminate it, what's there to be afraid of.

"Lao Zhang, you can go out." Li Changjiang shouted to Zhang Xiangqian in front of him.

"Me? Why should I go out? I'm still waiting to troubleshoot it, and then let's get started! Zhang Xiangqian shouted.

At this moment, the minds of the three were the same.

Is there a risk? Of course, there is a risk, and you may choke to death by drinking water, but now, since you have encountered a situation, you have to find a way to deal with it, and you will definitely not back down.

If you want to die, then everyone will die together!

A few years ago, their team had already been structured, but there was also an additional Wang Erzhu who was loaded with shells, they had been abroad, they had driven Chivoltan, and they all cooperated tacitly in all kinds of tanks.

Now, everyone has a lot of leadership tasks in the factory, only the initial experiment of this new model, will be started, but since it has come up, life and death have been put aside, what are you afraid of!

No one will go down, and at the same time, everyone still has expectations in their hearts, perhaps, with a mechanical firing, it will be all at once?

How to shoot, is also a science, at the beginning, there is no other way, the way to use is to point the twist, that era, is quite hard, everyone is holding the fire lighter, and then ready to light the fire rope, after the fire rope is lit, you have to wait for the burning to finish, that time, quite painful.

Later, there was a flintlock pistol, and the use of flint to ignite was considered to be more advanced, until modern times, with an advanced primer, the way of firing the primer to fire by hitting the primer was accepted by the public and became a widely used method.

On the shell, at first it was also the firing pin that hit the primer. Even if it is a rope shot, it is actually a smashing fire, but later, with the progress of technology, more and more advanced methods have appeared.

At present, the electric shock is directly applied to the primer of the propellant, and as long as the power is applied, the firing can be completed, and there is no need to hit the primer.

This kind of electric firing is also possible to malfunction occasionally, try mechanical firing!

With a smile on his face, Li Changjiang calmly and calmly turned the firing rotation button to the position of the mechanical firing, and then pushed the firing pressure lever fiercely.

Inside, the top iron began to be pushed, the toggle bolt was freed, and the internal toggle began to be plucked, releasing the firing spring and firing hammer, and hitting the firing pin fiercely.

The primer was pushed in an instant, and then, the primer quickly ignited the columnar propellant in the cartridge, and the blazing flame filled the entire barrel, and the high-temperature and high-pressure gas pushed the shell to fly forward and fly out of the chamber.

"Boom!"

The whole tank shook like this, the hull shook violently, and the muzzle of the gun, the blazing flame, fresh, dazzling.

For the first time, a domestic tank, a 125-mm tank gun was used to fire shells! This is a major breakthrough, and it is also an iconic monument!

Outside, everyone let out a long breath.

But, of course, it's not over yet.

How did this failure come about?

"We are already notifying the second machine factory, but we must first find the fault ourselves." When he poked his head out of the turret, Qin Zhenhua heard Luo Rongchang's words.

This cannon belongs to the No. 2 Machine Factory, and if something goes wrong, of course the No. 2 Machine Factory will have to be responsible, but it cannot shirk its responsibility, and it must also find the cause of the problem.

At this time, it is no longer important how much error there is after the shell is fired, and the problem of blind fire of the shell is solved first.

Wang Xiaoyu stood in the distance, looking at the flames coming out of the muzzle, and when she saw the cannonball flying out, her heart was also a burst of joy, boom! When the loud roar came, I only felt a throbbing in my stomach.

This little guy, who has not yet been born, is yearning for the launch of this artillery, right? And what about after that? Will the child in the womb grow up to be a military expert in the future?

Wang Xiaoyu stroked her belly, and secretly thought in her heart that at the same time, Qin Zhenhua and others had also begun to study it.

"There's no problem with the insurance tube." Liu Changjiang shouted.

When you start the inspection, the first thing you can judge is that there is no problem with the shell, and the problem is the electric shock device, so is it that the fuse is broken, resulting in no current passing through the inside?

The fuse is in good condition.

It takes a long time to study it all the way down the pipeline.

"It's weird, there's nothing on the circuit." After some inspection, I found that there was no problem with this circuit, and everyone was very curious.

"If it's all right, then it's on the side of the gun." Qin Zhenhua said: "When our shells are fired by electric shock, we must let the insulated firing pin against the primer to form a circuit, is it that we loaded the cannonball in the process of bumping, resulting in the cannonball not being accurately loaded, and the firing pin is not pressed on the primer?" ”

The shell of the propellant is an electrode of the circuit, and the bottom fire is another electrode, which needs to be used by the firing pin to transmit the current, and it is likely that it is not accurately contacted.

Moreover, this is still an occasional glitch that cannot occur every time!

Sure enough, after two more tests, the failure is no longer reproducible, and each time it was successfully fired.

What to do? Treat it as a chance accident and just give up?

Of course not! What if such a malfunction occurs on the battlefield? Although it can also be fired manually, the fighter may have already been lost!
