Hu Wenhai is a little strange, did he offend him by not personally inviting this director Xi Ya, why has this person's face been stinky since he saw him?

Even when Lin Qianjun shook hands with him, Xi Yaya didn't show much respect - although both sides had the word director on their heads, Xi Yaya was in charge of Wen Jiàn, who could fold paper airplanes, and Lin Qianjun was in charge of Wen Jiàn, who could buy F-14, and the gap between the two sides was slightly larger.

However, when he came to Lin Qianjun, he just didn't get a cold face from Xi Yaya.

Fortunately, Hu Wenhai and Lin Qianjun are not small people, and this Director Xi Ya is just a witness, and he doesn't need to approve anything.

Before leaving, Xi Yaya's superiors clearly instructed him to bring only eyes and not mouths.

Find out the specific performance of the new product, and as for the rest, you are not allowed to draw any conclusions.

Originally, I thought it was the superior's caution about the new product, but now, hey, it's just that the other party is arrogant!

If the effect of the product is not good - this is almost certain, laser guidance is so easy, can it be made in China for a long time?

If it's just that the effect of the product is almost good, then it is already God blessed.

I'm afraid that I won't be accurate at all, and then I insist on throwing it to the army to take over the pot, and the military industrial system has not done this kind of thing, and the 501 factory has many previous convictions!

No, as long as their products are not easy to use, even if they are criticized, I will expose their tricks on the spot!

The army has had such a hard time in the past few years, is it so indiscriminate to spend a little money!

With such a lofty sense of mission, Xi Yaya met with Hu Wenhai and Lin Qianjun in a silent and low-key manner, and then set off with the flow to the test site of the Xinke factory.

Although the last gliding shell did not have a charge, the cast-iron casing itself plus the electronics inside weighed ten kilograms, to say the least.

The power of being thrown from a height of 10,000 meters and finally turning potential energy into kinetic energy is very terrifying - it is equivalent to exerting 2,000 oxen of force on the wall in 0.2 seconds, and simply smashing the wall at once!

Therefore, this time, Hu Wenhai specially prepared a flexible target, so that he could intuitively observe how powerful the impact of the gliding missile body is.

As for what is a flexible target?

Ahem, it's just a big stack of scrappy newspapers and magazines.

The "uselessness" accumulated by the 501 factory over the years

Newspapers, that's only one percent of the volume.

After switching to the real yàn last time, this time the drone did not need to take off from the real runway of the Xinke factory, but took off from Xiucheng Airport.

The control personnel are still the instructors seconded from the aviation school last time, and it is said that after the production of realistic aircraft began in the 501 factory, the aircraft training in the sky of Xiucheng has become significantly intensive.

According to the feedback from the aviation school, the real machine has a very good effect on cultivating the driver's feeling.

In fact, I also want to know that the pilots before the fighter plane still have to fly the first six teachings, right?

If it's not that the feel is very important to the pilot, why waste time flying a fan machine that can't go to the battlefield at all.

In the same way, since they are all turbojet engines, there are common places in operation, especially the simulated aircraft also very carefully simulates the aerodynamics and thrust density of the real aircraft, at least the linearity of the middle part of the flight envelope is similar, and you can still have a perceptual understanding of the jet after flying for a long time.

With a thumbs up from the instructor of the aviation school here, Hu Wenhai hurriedly waved his hand and drove everyone into the trench dug last time.

However, this time was different from the last time, at least they were more prepared, and each person was given a steel helmet.

"Hey, Mr. Hu, what you're preparing is quite like that. ”

Lin Qianjun followed Hu Wenhai's guidance and jerkily fiddled with the laser target designator in his hand.

Because of the experience of the last time, the indicator does not need to be placed separately from the person, but can be moved by hand.

The carefully packaged laser target designator is nothing like the shoddy one it started with, with a heat-dissipation and dust-proof window, a pressed laser launch button, and most importantly, a visual rangefinder.

This thing is not difficult to say, the laser rangefinder is a very ordinary optical industrial product in later generations, and the principle is almost no different from the laser pointer.

The only difference is that the laser receiver mounted on the missile is also attached to the indicator.

This is coupled with a thermostatic crystal oscillator, which is a circuit that provides accurate standard time.

The time between emitting the laser and receiving the laser divided by two, multiplied by the speed at which the light travels through the air, gives a relatively accurate distance information.

But of course, the laser rangefinder of later generations was able to hold it with a small hand.

But now Hu Wenhai has created this, let alone one hand, and it will feel quite difficult to put two hands together, and the main weight is the battery added to supply the computing circuit.

If you use the world's dry batteries for power, you need eight No. 2 batteries!

After twenty or thirty years, you may not be able to find the specification of No. 2 battery on the market.

But now in the 80s, the power of the No. 2 battery is still quite competitive.

If you compare before and after, you should know how important lithium batteries, which have a high energy ratio, to the electronics industry.

According to Hu Wenhai's instructions, Lin Qianjun looked through the eyepiece behind the laser target designator that was erected, and sure enough, he saw a thin red line projected in the middle of his field of vision, which was the near-infrared laser dyed by the polarizer emitted by the indicator.

In addition, as Lin Qianjun moved the direction of the laser target designator, he found that there were small red lights on the right side of his field of vision that were constantly changing the number of lights up.

"Hey, Mr. Hu, what do these little red dots mean?"

Lin Qianjun asked curiously.

"This is the distance between you and the indicated target measured by the laser rangefinder, a red dot lights up to represent one meter, count the number of red dots to know the number of meters from the target. ”

"Oh, that's good!"

Lin Qianjun's eyes lit up, and he said excitedly: "With this, isn't it possible to report the coordinates of the shelling anytime and anywhere?"

Not to mention that Lin Qianjun really has the goods in his stomach, Hu Wenhai just introduced the ranging function of the laser target designator, and he immediately realized the huge value in it.

In the war of self-defense and counterattack in Annam, our army and the Annam army always regarded the battle for the top of the hill as the key point of the war, and one of the biggest reasons was the need to serve as an artillery observation point.

Standing on a high vantage point, no one will send out the air force, and naturally the army itself can only rely on the army itself to discover the enemy's artillery positions or valuable targets.

However, even if we have achieved the hilltop position, the knowledge level of our soldiers is generally not high, and the ability to command the artillery to launch strikes is not competent, so the artillery unit can only send artillery observers -- this is a more valuable sniper target on the battlefield than the officers!

Not only that, because the distance measurement uses triangulation.

One artillery observer is not enough, at least two points must work together to calculate the distance, and finally generate a number of coordinates that can be provided to the artillery unit.

It is said that the Iran-Iraq war was a low-tech war under high-tech conditions, but in fact, in the Annan self-defense counterattack, the two ** teams of China and Annan were even worse, and they were just engaged in a ground war at the level of the world's 50s.

And with a laser rangefinder is different, our army no longer needs to storm the mountain, no longer need to send dangerous artillery observers, no longer need two-point measurement, can provide meter-level accuracy of position information...... This is a tool that can change the whole pattern of warfare -- the pattern of warfare at the level of the 50s in the world, but it is also remarkable.

This will be essential to the current improvement of the combat effectiveness of the PLA Army.

Even if the accuracy of the final laser-guided weapon is not good, at least this laser target designator must definitely be included in the ranks of equipment procurement.

"Heh, who knows if this thing is a predetermined number of jù they measured, as if it had planted explosives in advance during the exercise. ”

Xi Yaya pursed his lips and retorted with some disdain, obviously with skeptical glasses.

"This is easy to do, the number measured in advance can definitely not be used to guide the missile, as long as the missile hits the target, it naturally means that the laser ranging is also easy to use. ”

"Hmph, who knows if you also measured the number of targets in advance and gave them ...... missiles."

Xi Yaya suddenly couldn't say any more when he said this, because he realized that even if he measured the number in advance and fed it to the missile, it wouldn't explain anything.

Because of this "cheating"

The method is not cheating at all, it has another name, it is called - inertial guidance.

If inertial guidance hits a target the size of a paper stack, this is an exaggeration than laser guidance technology.

"Haha-"

Hu Wenhai and Lin Qianjun looked at each other and smiled, obviously aware of the contradictions in Xi Ya's words.

At that moment, the familiar hiss suddenly sounded in the sky again.

Just like last time, almost the next moment everyone heard this voice, touch!

A loud bang rang out, followed by scraps of paper scattered in the sky.

"Is this, hit?"

Although Lin Qianjun has a lot of trust in Hu Wenhai, he still has a sense of unreality when he really faces this fact.

Xi Ya impatiently climbed from the trench to the ground, and hurried to the target despite the obscuration of paper and dust.

Who knows if it's late, will there be any means to fake the scene?

With his hands, he fanned away the dust that obscured his vision, and gently peeled open the loose stacks of paper—the cast-iron bullet casings that had been shattered, and the faintly visible circuit batteries, and the glass lenses, just like the inlaid between the waste newspapers and books!
