With a surprised gaze, Xie Huimin saw Qin Zhenhua take out a piece of paper from his pocket, which seemed to be placed in his pocket very casually, if it wasn't for the paper being a particularly hard drawing paper, it would make people think that it was used to go to the thatched house, and after the paper was unfolded, the clear design drawings appeared in front of Xie Huimin's eyes.

"This, is it a swinging loader?" Xie Huimin couldn't hide his surprise in his eyes, and asked Qin Zhenhua.

Tank guns can be reloaded automatically, but when reloading, they need to be reset to a certain angle, why is that?

Of course, because of the problem of loading, the shell must be parallel to the barrel to be stuffed in, in the tank, this is not very complicated, after all, the tank gun was originally mainly used for flat shooting, the elevation angle is not high, but, howitzers and the like, the elevation angle is often not low, at this time, it is necessary to reset before it is convenient to plug the shell, because even if there is an automatic loader in the back, it does not move.

In order to avoid this effect, there is a swinging loader, which can swing in the back, and after the barrel is rotated, waiting for the loaded shell, it will be in a parallel state with the barrel at any time, so as to meet the needs of automatic reloading.

It's just that this requires a lot of space, which is not in the tank, but the space in the hull and turret behind the self-propelled gun is reserved, and you can use it however you want, which creates conditions for a swinging loader.

After all, it takes time to lower the artillery, then reload the shells, and raise them again.

Now, with this way, it is possible to significantly reduce the time of reloading shells.

However, on the other hand, how to put the shells to be loaded on this oscillating loader is another problem.

If the loader does not swing, the shells in the rear turret tail compartment are parallel to the loader and can be output directly, but now, the loader swings back and forth, which causes the shells in the tail compartment to have an angle with the loader.

Either the barrel is moving, or the ammunition magazine is moving, and this is a new problem.

"The ammunition in the tail compartment is moved to the loader by the loader, and then the loader loads it, which is what I call semi-automatic loading." Qin Zhenhua said: "How? ”

There are many problems to overcome with automatic loading, in addition to the need to come back every time the barrel is fired, there are other problems, such as choosing the type of bullet!

An artillery, there is absolutely more than one type of ammunition, even if it is a howitzer, there can be other differences such as anti-personnel grenades and explosive grenades, etc., take the current self-propelled anti-tank gun as an example, the main ammunition type is naturally the tail stabilized shelling armor-piercing shell, but, if necessary, it can also be used as a grenade.

Automatic loader, how to identify ammunition?

The French Leclerc tank was identified by the barcode on the shell, and the Soviets simply prescribed that certain ammunition should be placed in certain bomb bays.

What about yourself?

Just leave it to the manual to do it!

In the past, when loading ammunition manually, it was necessary to move out the shell, wait for the fire to be fired, open the gun door, stuff it into the gun chamber, and close the gun door to complete the loading action, and wait for the launch before moving the next shell.

And now, all you need to do is the loader, remove the shell from behind, put it in the position to be reloaded in this semi-automatic loader, and leave the rest to this semi-automatic loader to solve!

This can be regarded as a creative invention, Qin Zhenhua took the design drawing of this device and explained it carefully, and Xie Huimin at this time was already stunned.

"Boy, you've already designed this plan?" Xie Huimin looked at Qin Zhenhua, although the alcohol had already gone up, he still reacted: "Boy, it's really unkind!" ”

This semi-automatic loader must have been designed by Qin Zhenhua for tanks!

As designers of tank factories, they need to be prepared with both hands, whether it is a 120 mm tank gun or a 125 mm tank gun, they must have a backup plan.

After all, it is not certain which one will be chosen in the end, and what if the upper side tends to maintain the same caliber as the West, and use a 120-mm tank gun?

At that time, the problem of loading had to be solved by a machine factory, Leclerc's loading method was high, and there were too many uncertainties, Qin Zhenhua and others just designed such a set of semi-automatic loaders, which greatly reduced the labor intensity of the loader.

After all, it is enough to move the shell and put it over, but if it was before, it would have to be several movements, holding fifty catties of white flour in both hands, trying to lift it up and stuff it into a certain place? It's too strenuous, but now, just a little tanker can do it, just by moving it.

Boy, since you have this plan, why didn't you come up with it at that time?

If it had been taken out at that time, perhaps the upper authorities would have agreed to the plan for a 120 mm tank gun?

"Actually, we are not satisfied with this plan." Qin Zhenhua said: "It still needs the turret tail compartment, and it still needs a large space. Four more people were squeezed in the turret. So, on a tank, it is not suitable, in the case of self-propelled guns, then it is just right. ”

Qin Zhenhua didn't lie, that's what he thought, now, when he took out the thing at the bottom of the box, his heart was hot, this design idea, in fact, was also in that red book, but his father didn't have a chance to perfect it at that time.

Father, I'm making it a reality little by little!

Specifically, this is called a semi-automatic loader that manually picks up bombs and automatically feeds them at fixed points. If done well, it can achieve a maximum feed speed of 14 rounds per minute, and can also complete 3 rounds per 18 seconds and 5 rounds per 30 seconds, and in a normal ideal state, 10 shells can be fired in one minute.

In this case, a self-propelled anti-tank gun ambushed in a camouflaged preset position, with only the muzzle exposed, could kill a Soviet T72 tank company in 1 minute.

That's right, self-propelled anti-tank guns do this job, once they fire, they will immediately kill the other party, as long as there is a delay, they will be killed by others, and the thin armor can only prevent a machine gun bullet from firing, and once someone's shells fly over, the self-propelled anti-tank gun will have to be blown away.

"In this way, all the problems have been solved, and this project is currently regarded as a cooperation project between our two factories, how about it?" Xie Huimin asked.

Qin Zhenhua shook his head again and again: "No, absolutely not, this project is from our factory, we need to pay us for it, we build the car body, install tank guns for you, and give you a semi-automatic loader." Our factory will not invest a penny. Our money is not blown by the wind. ”
