The target is located 5 kilometers away, and Wang Zhen ordered the soldiers to prepare it when he came, with the red target as the center, and drew several white straight lines, on which the distance was marked.

The high expert zoomed in on the screen, clicked on the target, and immediately a string of data appeared.

Altitude, distance, wind speed, humidity......

With one more click, the 12-tube 107 fire on the pickup truck turned and automatically adjusted the firing angle.

In about 10 seconds, the green launch button on the screen turned red, and a dialog box popped up after the expert clicked, please enter the password or fingerprint.

The index finger clicked on the fingerprint lock, and the screen immediately flashed red, and on the pickup truck next to it, "Whoosh!" ”

A rocket slammed into the sky, streaking across the sky with a bright yellow tailfire.

The body of the car began to shake slightly, but the amplitude was noticeably smaller, and it quickly returned to a steady pace, and after three seconds, "Whoosh! ”

When the rocket launches nest, it is not one after another, it must be spaced at an interval of about three seconds, otherwise the rocket in front of it will cut the burning air to form a channel, which will greatly reduce the wind resistance of the rocket behind, which will only make the previously measured data completely invalid, so that the warhead does not know where to fly.

And when launching, it is not side by side, one after another, it is generally diagonally up and down, and try to stagger as much as possible.

Everyone glanced at the vehicle a few times, and after determining the amplitude of the vibration, they retracted their eyes and looked at the screen with satisfaction, and at this time, the rocket finally flew to the target position, "Boom!" ”

"Boom!"

"Boom!"

"Boom!"

The firelight completely covered the shooting range, even if it was shot in the sky, the firelight and the smoke and dust raised by the explosion made it impossible for everyone to see the specific landing point, and soon, the smoke and dust were completely connected!

Just look at the range of smoke and dust, you can know that the landing points should be relatively close, and there is no such state that one in the east and one in the west, separated by hundreds of meters, cannot be connected to each other.

From this, it can be judged that the landing points are not far apart.

Kiel and the others around him glanced at each other, and they all nodded.

Sure enough, after waiting for about ten minutes, the smoke and dust dispersed almost, and from the air, if the red target that had just been locked was the center, the 12 rockets were all within a radius of 200 meters.

5 km, with a radius of 200 meters, it looks like the accuracy is rubbish.

However, the accuracy required by different weapons is different, and the meaning of the existence of rocket artillery is to strike in a large area, because its launch will inevitably cause the carrier to shake, and the landing point of the shells behind it will inevitably be affected.

When the rocket artillery is launched with a nest, the accuracy is judged by the radius of the landing point, the farther the distance, the larger the radius of the landing point, if the pickup truck does not have support feet, no matter how accurate the measured data is, the radius of the landing point will exceed 500 after 5 kilometers.

Of course, it is not impossible to be smaller, and installing a mechanical gyroscope on the base of the 12 nests can further reduce the vibration amplitude, but no!

The landing point error is too small, and it is covered with a ball of yarn!

"Bang bang." Kiel was the first to applaud, and the applause rang out.

"Party expert, what did you just use?" Kiel smiled and looked at Dang Haobing.

He was very curious that the APP actually turned the launch process of rocket artillery into a fool's style, which is simply too suitable for the South Soviet Army!

No one knows better than him that the literacy rate of soldiers in the army is less than 20%, and it is a fool's dream to expect them to learn how to aim with optics, how to calculate the angle of launch, and how to adjust the direction machine.

Those guys will just put the launch vehicle in place by feeling, and the direction is almost the same!

Whether it is a conflict between the North and the South and the Soviet Union or an internal conflict, in fact, such over-the-horizon weapons are rarely used, and most of them are flat-fired......

It's not that I don't want to wave my hand and wipe out the enemy, but I can't do it!

"This is a set of fire control system developed by us, with the help of drones and mobile phone networking, with APP to complete the launch preparation, fingerprint or password recognition, high security." Dang Haobing introduced with a smile.

"Good, good." Kiel complimented again.

"Wang, are there any other surprises? I can't wait. Kiel looked at Wang Zhen.

"Of course." Wang Zhen personally went to pick up an RPG launcher and came over, "With the 107 rocket launcher, how can there be no RPG in the guerrilla artifact, everyone is familiar with it, there are many launchers, but the warhead is the key problem that bothers everyone." ”

"What I want to say is that the warhead is actually not very high-tech, after all, it is the technology of the 60s, and we can completely realize it in the South Soviet Union."

As he spoke, Wang Zhen took out a warhead and dismantled it on the spot.

Okay, I learned from Lao Liu before I came, but this limelight Wang Zhen has to come out by himself.

"From beginning to end, the front is a piezoelectric fuse, usually a plastic cap is worn to protect it, and there is a safety with a strap attached, which needs to be pulled out before launching, the hollow powder cover and charge in the head, after the charge explodes, squeeze the powder cover to form a high-temperature and high-speed metal jet to penetrate the armor, followed by a conductive body and a detonating detonator, which is equipped with a delayed self-destruct device, which self-detonates about 5 seconds after the rocket leaves the launch tube."

"The warhead has several grooves, which are used in the same way as rifling, to rotate the projectile, here is the acceleration nozzle, about 10-20 meters after the rocket leaves the launch tube, the rocket propellant is ignited, and it is sprayed from six small nozzles, which can accelerate the rocket to about 300 m / s, which is similar to the nozzle on the butt of the 107 fire."

"Then there is the tube behind the warhead, which is equipped with propellant, which is the main power of the RPG, and the range depends on how much charge there is, of course, there is no need to load a lot of the actual situation, and it will not hit if it is far away, and behind the tube is the firing trigger device."

"The last one is screwed on before launching, and it is mainly a metal rod, trimmed, otherwise the front propellant will burn less and less, and the center will be inverted and shifted, and the flight trajectory will become uncontrollable, and the metal rod will have a folded tail on it, which will be opened after launch, so that the projectile body will rotate and maintain the trajectory."

"The rear of the metal rod is the propellant and turbine blades used to push the rocket out of the launch tube, after all, it is carried on the shoulder, it is impossible to use propellant when it comes up, the jet of high-temperature flames can burn the launcher on the spot, and the air flow generated by the explosion of the propellant washes through the blades to make the rocket start to spin and fly out of the launch canister."

"After 10 meters, the acceleration nozzle erupts violently, instantly accelerating the rocket, and then the propellant maintains a steady thrust."

"So, speaking of which, the only processing difficulty is in the propellant."

"The demonstration of the 107 fire has just proved that we can configure propellants, so we have developed a lot of weapons based on propellants!"

"Conventional jet armor-piercing warheads, high-explosive warheads, incendiary warheads, these are known to everyone, I won't demonstrate, and now the one I demonstrate is the air-burst version!"

"As we all know, after the grenade lands, the collision fuse detonates the explosive, and most of the fragments are either sprayed into the sky or hit the ground, and there are not many that are really used to kill targets."

"The air explosion is different, most of them are used to kill targets, and within the killing range, it is useless whether they lie down or hide in the trenches, and they have very low requirements for accuracy, which is very suitable for our fighters." Wang Zhen said very directly, "Next, let me demonstrate." ”

"The target is 300 meters away, party expert!"

Dang Haobing immediately clicked on the APP, clicked on the RPG air burst bomb, and immediately came up with a number, "1.13 seconds." ”

“OK。” Wang Zhen pressed a few times under the small LCD screen of the bullet body, and this action immediately attracted everyone's attention.

Subsequently, on the shoulder, do not aim directly pull the trigger, whoosh, boom!

It was clear to everyone that the warhead exploded at a distance of 300 meters.

"Wow, what's going on!" Kiel asked with wide eyes, RPG he had used it many times, and in the case of air explosions, the advantages and disadvantages did not need anyone to explain to him, he understood.

But what he couldn't figure out was why no one had designed a similar warhead before?

This is obviously not a technical issue!

Wang Zhen smiled lightly, "It's nothing, it's very simple, add an electronic fuse, a small part on the electronic watch, and the timing is accurate to 0.01 seconds." ”

Wang Zhen gestured to a fingertip universe, "I pulled the trigger and started the countdown, and when the time came, it would automatically explode." ”

In fact, it is very simple, produce products, send the data to China, the computer runs the trajectory, and then combines the measured data to obtain a relatively accurate trajectory table, put it into the APP, and directly produce the results.

"Genius-like thoughts!" I don't know if Kiel really understood or fake, but he took the lead in applauding anyway, and then the others immediately followed, looking clear.

After everyone applauded, Wang Zhen continued: "Actually, this warhead we designed is not only aimed at the army. ”

"After all, there are a lot of weapons against infantry, there is no need to add another one, its real target is a helicopter in the air!"

In a word, Kiel's eyes widened suddenly, "You mean ......"

"Yes, the target can be calculated not only with a drone, but also with a carry, quickly calculate the flight altitude of the air target, and then, boom!"

"Fack, you're a fucking genius!" Kiel was overjoyed, and this time was even more surprising than seeing an incendiary bomb.

There is no cover in the air, and the radius of destruction is a global radius of 100 meters!

One warhead may not pose much of a threat to a helicopter, but if multiple warheads are used at the same time, they can completely block an airspace, which is too much of a threat to helicopters!

The problem of air defense has always been a big problem for these African countries!

Hit high and low, hit fools, helicopters hurt the ground forces too much!

Of course the stinger is good, everybody knows it, but you have to be able to get the fuck on it!

The United States sold a lot of them to the poor people to use against the Soviet Union, but after the collapse of the Soviet Union, all these weapons were fucking used against the Americans......

Since the loss of a large number of helicopters in Afghanistan, the United States has begun to strictly control the sales channels of Stinger anti-aircraft missiles.

Even Russia's Arrow-2, Arrow-3 and Needle series of man-portable anti-aircraft missiles have begun to be strictly controlled.

This is not to say that Russia is afraid of the United States, but the common will of the ruling class!

Helicopters, private jets, standard for the regal!

If it is targeted by a portable missile at the stage just after takeoff, it is almost certain to die!

If man-portable anti-aircraft missiles are proliferated like RPGs, the rich should not be able to sit still!

After all, Franklin was dyed with blood.

Kir really didn't expect Wang Zhen to bring him such a big surprise! (End of chapter)
