A big country of aerospace with black technology

The drones that followed Zhang Xingyang and flew at ultra-low altitudes did not end well.

Basically, they were 500 meters away from the laser weapon when they were irradiated by the laser, and then fell to the ground hard.

Most of their drones use electric motors, which are not very fast and their acceleration is not as good as Zhang Xingyang's own drones.

In fact, laser weapons have been able to shoot down their planes from the beginning.

The reason why I waited until I got close before shooting down was entirely because of the angle of the camera.

The lower limit of the laser's irradiation angle can reach -22.5 degrees, and the upper limit is even more exaggerated, allowing almost direct vertical irradiation.

The range of fire of traditional anti-drone anti-aircraft machine guns is much larger.

Although the panoramic camera can capture 360 ​​degrees, the shooting distance is very short in the area close to the horizontal plane where you are.

This is why the plane controlled by Zhang Xingyang was only discovered when it was one kilometer away.

"The interception rate is 100%. Except for your plane, each interception time is between 0.2-0.5 seconds."

By the time Zhang Xingyang returned to the location of the laser air defense weapon, Geng Bo and the others had already compiled the data for this weapons experiment.

A 300-kilowatt laser has weapon-level laser intensity. An ordinary laser cutting machine can cut a 10-mm steel plate with a 1-kilowatt laser.

Although at a distance of one kilometer, the energy will be attenuated due to the atmospheric environment, when the weather is not bad, the attenuation is still very weak.

Today is still a sunny day, not to mention clouds and rain, not even fog.

Laser can directly act on the shells of artillery shells, rockets, and drones with almost no attenuation.

Cannonballs are generally made of steel or copper shells. Copper has better thermal conductivity than steel, and the irradiation time required is basically twice that of steel.

As for drones, they are basically the easiest to ignite, because the shells of most drones are plastic, and some are even made of wood.

Because the power of the electric motor is limited, if a metal body is used, it will fly slower and the cost will become very high.

"It seems pretty good."

Zhang Xingyang looked at the record made by Geng Bo and said, the laser generator on one side was still urgently removing the exhaust gas it produced.

There are also many people checking whether the explosive generator is in good working condition.

In particular, whether there are cracks in the two storage tanks storing liquid oxygen and liquid hydrogen, there are dedicated personnel holding ultrasonic flaw detectors to check whether there are cracks.

"The next test, start as soon as possible!"

Closing the folder in his hand, Zhang Xingyang looked at the personnel in the distance who were still working to put out the fire of the burning drone that fell to the ground and said.

This test site actually has no trees and is a relatively desolate area.

So there is no need to worry about fire issues.

For the laser air defense system, the first round of testing was to design low-altitude and low-speed drones in manual mode. The second round of testing has become much more difficult, adding faster and smaller artillery shells and rockets.

As for the third round, it is even more difficult and can basically be regarded as simulating actual combat scenarios.

Several 105 howitzers will fire a base number of shells, and the number of 107 rocket launchers will also have a similar base number.

UAVs will also be officially upgraded from the previous aircraft model level to military level, with better workmanship and parts, faster speed and more flexibility.

The most important thing is that the number of drones will be increased to 120!

Through programming control, a suicide drone attack cluster is automatically formed.

It is no longer controlled by the pilot, but the chip automatically controls it according to the program programmed in advance.

This project is more complex and takes longer to prepare.

It was not until the next day that the preparations were completed.

"Are you confident that you can intercept so many attacks?" The old chief who arrived temporarily looked at the firepower configuration in the plan and asked with some disbelief.

This kind of firepower actually exceeds the firepower of a battalion, and these are heavy firepowers!

Such firepower, placed on a front line, is enough to blast a gap of at least several hundred meters.

This is only counting the 105 howitzers and 107 rocket launchers, and the 120 suicide drones have not been taken into account.

"Honestly, we don't know how many interceptions we can intercept."

Zhang Xingyang openly admitted that he didn't know whether he could stop so many attacks.

"After all, we have never tried this kind of firepower density before."

"But theoretically speaking, it is not difficult to achieve an interception rate of 90 percent."

Zhang Xingyang's statement is actually quite conservative. According to other people who experienced yesterday's experiment, they all believe that even with such a density of firepower, it is very simple to intercept it.

"Well, I'm looking forward to your performance!"

After the old chief smiled, he patted Zhang Xingyang on the shoulder and said.

The third round of laser air defense experiments began soon.

Among the three weapons used for testing, the 107 rocket launcher has the fastest firing speed.

The slender rocket launchers, spitting out flames, flew away from the launcher.

This time the scope of the test site became larger, with a radius of 60 kilometers covered.

The rocket launcher is located in the northeast direction of the laser weapon. The rockets flying along the sunlight appear more obvious in the sunlight.

When the laser weapon was still 8 kilometers away, the rocket was detected by the laser air defense system.

In fact, the maximum range of the 107 rocket is only 8.5 kilometers, which means that the rocket was discovered by a high-definition camera as soon as it took off.

The explosion generator started working, and violent noises began to resound throughout the entire air defense position.

The gas laser generator located above quickly adjusted its azimuth angle, and a lavender laser shot out, penetrating the outer steel shell of the rocket almost instantly.

After a hole appeared on one side of the rocket, the missile body instantly became unstable. The originally excellent aerodynamic shape began to have numerous turbulences, and it spun and flew to unknown places.

Because the 107 rocket adopts a flight method similar to that of artillery shells, it uses spin to stabilize its own trajectory. After instability, it is extremely easy to deviate from the target.

The offset target is still good, at least it can land, and the collision fuse may be able to detonate.

But those rockets with a slightly longer exposure time do not have such treatment.

After the laser burned through the outer shell, it continued to ignite the explosives inside, and a beautiful firework exploded directly in the sky.

The automatic shooting mode of the laser air defense system has a variety of preset models, allowing it to be freely switched under different situations.

For example, if there are many target flying objects, the illumination time of each target will be automatically reduced, and the target will be shot down in the unit time.

When there are fewer flying objects, the exposure time will be lengthened and the explosives will be detonated directly in the sky.

In less than a minute, 12 107 rockets were either shot down or exploded directly in the sky.

This was also a one-time projection of firepower from a 107 rocket launcher, and it was simply shot down.

The army officers who accompanied the old leader were a little shocked.

After all, anti-aircraft missiles are too expensive these days, and the interception rate of anti-aircraft machine guns and anti-aircraft guns is very low.

The Army is actually also thinking about how to have a weapon with low cost and high interception rate.

The emergence of laser weapons undoubtedly dazzled them.

But such a high interception rate of laser weapons makes them find it a bit hard to believe.

Because it is generally recognized that China is not very advanced in the field of lasers, will there be more powerful laser weapons abroad?

It caused many people present to think deeply.

"You did a good job!" The old chief was not like others, because he had long known that there were ways to deal with laser weapons in the country.

At this time, the 105 howitzer on the side had also completed preparations.

Amidst loud reports from the artillerymen, the firing began.

After pulling the firing rope hard, the cannonball came out in a burst of fire.

The speed of cannonballs is similar to that of rockets.

It's just that the shells are smaller, and the positioning accuracy requirements for the laser are also higher.

The take-off speed of the UAV group is the slowest, because these UAVs need to use ejection devices to launch into the air.

Although there were ten catapult devices on site, each catapult device had only ejected one aircraft at this time.

According to the schedule, it will take at least half an hour to complete the takeoff.

The maximum rate of fire of the 105 howitzer is basically 8 rounds per minute.

It is not easy to achieve the maximum rate of fire on the battlefield because there will be various interference conditions.

But today they were able to use the howitzer's maximum rate of fire, and shells came out one after another.

A base of 80 rounds of artillery shells lasted nearly thirty minutes.

Because these 105 howitzers are all old guns, we had to stop and let them rest for a while after hitting the back.

In the sky, arcs were constantly drawn, which were the shadows of cannonballs.

Before the naked eye could see clearly, a lavender laser shot from a distance invisible to the human eye and exploded them in the air.

There are only three 105 howitzers in total, and they can only fire three shells at a time. There is basically no pressure on the laser interception system.

So all the shells were detonated in the air.

Unlike firing 12 rockets at a time, it puts a lot of pressure on the laser interception system.

Just when the laser interception system slowly fired off one 105-mm howitzer.

There are more and more drones taking off at the take-off ground.

Most of the drones are still hovering in the sky, waiting for all the drones to take off before conducting flight grouping work.

The work of a formation of 120 drones is still a troublesome thing in this era.

Zhang Xingyang adopted a rather tricky approach and organized every 12 drones into a flight group, which greatly reduced the overall grouping capacity.

However, the formation of the entire cluster becomes less flexible.

Huge 12-machine formations circled in the sky, like a group of crows announcing their death.

"This battle is huge!" the old chief said thoughtfully to the officers around him.

Many military officers around also thought that this technology could actually be applied in the military.

Install high explosives and collision fuses in the belly of the aircraft, and then group them into groups to hit the ground to complete the explosive attack.

Because it is an initiation attack, it should pose a considerable threat to heavy armored targets.

As the last drone took off, the howitzer on the other side had finished firing.

All the howitzers were detonated in the air and turned into gorgeous fireworks.

"The drone formation is completed, start the attack!"

With a loud shout, the blades began to rotate at a faster speed, and the electric motors boosted the aircraft's speed to 220 kilometers per hour.

This speed may be very fast for a car, but for an aircraft, it is basically considered a low speed.

However, drone swarms rely not on speed, but on huge numbers.

The drone take-off site is nearly 30 kilometers away from the laser air defense system.

This is also the maximum effective range of the 300 kilowatt laser generator.

Although the laser is also powerful 30 kilometers away, according to calculations, each target must be illuminated for more than 1 second at this time.

This is somewhat of a loss.

Therefore, everyone set the range of the laser air defense system at 30 kilometers.

Ten drones were grouped together and flew in a flying goose formation. The several drones in front were all reinforced models with boron phenolic resin coating.

Specifically designed to deal with laser weapon irradiation.

This is the final test, which is very difficult.

After the drones took off in formation, they were soon greeted by the first wave of laser attacks.

Although boron phenolic resin was used to strengthen the drone's body, it was still shot down after being irradiated with laser for twice as long.

Within a minute, like a flock of geese being sprayed by trolls, more than twenty drones fell down.

At this time, the drone had only flown about four kilometers, and there were still more than twenty kilometers left from the laser system!

The drone formation was constantly changing its formation, intending to delay the attack time of the laser system.

The formation spread out into wide formations to increase the turning time of the laser air defense device.

If you can delay for one more second, you can advance an extra 100 meters!

Every two hundred meters, a drone falls to the ground!

Especially when the distance is closer, the laser irradiation becomes more powerful, and the drone falls faster and faster!

From one hundred and fifty meters, to one hundred and twenty meters, and then to eighty meters!

When the laser weapon reached 1,500 meters, only three drones were left.

But it was obvious that it was impossible for them to reach the intended target point.

Just when everyone thought this experiment was over.

1,340 meters away from the laser weapon, the last drone suddenly opened its belly.

A short stick, no more than 20 centimeters long, fell out!

Then the people watching the test site with surveillance cameras looked in surprised eyes.

Behind the butt of the stick, dark blue flames erupted, erupting at extremely fast speeds, at least Mach 8!

In less than half a second, he rushed directly in front of the laser weapon device. After a muffled sound, a large cloud of smoke came out.

"What is going on?" Geng Bo stood up in surprise and said.

There was nothing like this in the experimental plan.

At this time, the previously calm old chief was also surprised. He thought this was an arrangement.

Didn't expect it to be an accident? (End of chapter)
