"Wang Gong, as the assistant director of the No. 1 Machinery Factory, I order you to agree to Qin Zhenhua's request." Qin Zhenhua said to Wang Xiaoyu.

As soon as this sentence came out, the atmosphere froze, and Liu Dajun looked at Qin Zhenhua like a monster.

How capable are you, dare you say that? After a while, aren't you afraid that Wang Xiaoyu will eat you? Hehe, I will give you a face in front of people, tonight, I went back to the dormitory, a bed, will I not let you get into the bed? Or will it make you kneel on the washboard?

Liu Dajun thought maliciously in his heart, and at this time, Wang Xiaoyu glanced at Qin Zhenhua: "Since you ordered me as the assistant to the director of a machine factory, then I agreed, but if it is this identity, where am I qualified to agree to your request." You are contradicting yourself. ”

Who are you? Is it the status of the assistant to the factory director, or the identity of my husband? Wang Xiaoyu glanced at him, and then turned around and left: "Unload our equipment and install it on their tank!" ”

This kind of equipment, officially called the laser simulated engagement system, has a large number of mature equipment that can be used since the eighties.

This system, if you put it in detail, mainly includes three subsystems: the shooting system, the target system, and the training data retrieval system.

Of course, it is also easy to understand that the shooting system is a system used to simulate the launch of artillery shells, which includes a transmitter/receiver, an explosion and smoke simulator, a vehicle interface device, and the target system is to detect those laser beams that are emitted, including a backward reflection detector, a vehicle body occlusion detector, a destruction indicator, a target computer, and so on.

And this training data retrieval system is mainly the equipment required for post-training evaluation.

This is a rather complex optical system, and since it is an optical system, the most important element is optical.

For example, its transmitter/receiver, this device is used to emit lasers, different countries, have different practices, for example, some countries make it into a long tube, the right size, can be stuffed into the barrel, simulating the gun line, and then, all the way from the barrel to the rear of the car body, connected with a data link.

Remember in a second https://

And Wang Xiaoyu did not do this, because the current domestic equipment is complex, there are 100 mm rifled guns, 100 mm smoothbore guns, 105 mm rifled guns, as well as 120 mm smoothbore guns, 125 mm smoothbore guns, so many guns with different calibers, if they are made inside the barrel, it will be diverse.

If it is not made into the inside of the barrel, it will naturally be tied to the top of the barrel, this set of devices, get a special bracket, fix it on the barrel, different caliber barrels, convert different brackets, quite convenient.

Now, seeing that the small box was installed on the barrel, the cable rotated around the barrel a few times, and then stuffed into the turret, Qin Zhenhua couldn't help but walk up again, and said to Wang Xiaoyu: "I'll help." ”

"Is it the identity of the assistant to the factory director?" Wang Xiaoyu didn't look at him, and her tone was flat.

"It's your husband's identity." Qin Zhenhua knew that the joke just now was a little inappropriate, but the couple had already made a heart-to-heart relationship with each other, and they wouldn't really be angry.

"Then you go back to the No. 1 machine factory and take care of the National Day." Wang Xiaoyu said.

The two are busy with work, and neither of them has much time to take care of the children, and now, when Wang Xiaoyu says this, Qin Zhenhua's heart is ashamed. A husband's responsibility, a father's responsibility.

Feeling the silence of the man behind him, Wang Xiaoyu turned his head, glanced at Qin Zhenhua, and then smiled: "If you have any questions, just ask, don't pretend." ”

She naturally knew that her husband was not intimate with her when he came here, and there were doubts.

At this time, Liu Dajun and the others also pricked up their ears and listened.

"The laser is straight, but the shell is curved, let's rely on the laser to indicate the target and determine whether to destroy it, is this appropriate?" Qin Zhenhua asked.

This kind of tall system has been available abroad, and the first generation has been developed by itself, but it is not known whether this can be realistically simulated.

If it's a simulation of firearms, forget it, after all, the bullet will hit one or two hundred meters, and within the usual combat distance, it won't be too much of a problem to replace the falling bullet with a direct laser, at most it will be aimed at the head and hit the chest.

However, tank guns are different!

Is this simulation system accurate or not? What's the point if it's not exact?

"You're only half right." Wang Xiaoyu said: "It's not just a matter of straight lines and curves, the shells fly out, it takes a period of time, for example, a 1,000-meter target, the shells will fly for about 0.7 seconds, and what about our lasers? 3 microseconds can pass, so if these problems are not solved, then the simulation system is not mature. ”

"So how do we solve it?" Qin Zhenhua asked.

"You see, the laser over here can move, and the laser it emits will change." Wang Xiaoyu said: "Therefore, when the laser is launched, the simulator will be constantly adjusted according to the trajectory of the shell flying out, it can simulate the trajectory of the whole process, and our tank sight, when installing auxiliary lenses, you can see the tracer trajectory simulated by the laser with the naked eye." ”

Hearing this, Qin Zhenhua was stunned: "How did this happen?" ”

That's too lofty, isn't it? The laser is constantly simulating the ballistics of artillery shells! He knew in his mind how much technical strength it would take.

"In addition to the laser with a control mechanism, a microcomputer and a gyroscope are installed in our transmitter / receiver, of which the microcomputer is used to store the ballistic characteristics of the shell, and the gyroscope, which is independently stabilized by the laser."

Gyroscope! This is a tall thing, inside the tank, only in order to achieve the stability of the tank gun, the gyroscope will be used, and now, this laser simulation countermeasure system, there is actually such a tall thing!

However, after a little thought, Qin Zhenhua understood.

It takes time for the shell to be launched and fall on the target, although it takes about a second, but during this time, the tank is going to move, the turret of the tank may rotate, and the hull may also move, so that the laser tied to the muzzle of the gun has to move with it, and the laser must be stabilized with a gyroscope in order to simulate it according to the trajectory of the shell.

It takes a lot of effort, but it's also meaningful because it accurately simulates the trajectory of the shell!
