Thirty meters at a low altitude.

Twelve firefighting drones, like ghosts, hovered quietly.

The advantage of the propeller is that there is no tail flame and the noise is low.

On such cloudy nights.

Except for night vision, it is not visible to the naked eye at all.

Even if you can hear the sound.

It is also difficult to find the location of the drone.

Tang Rui moved his mouse and marked a point on the map.

Then select the drone and click on the stealth mode.

Woowoo......

After receiving the order.

The optoelectronic system of twelve firefighting drones began to work.

Ground scanning system.

Laser ranging system.

Optical detection system.

Infrared detection system.

These devices, which are distributed on different UAVs, are turned on at the same time.

The obtained data, under the sharing and distribution of the multi-machine linkage intelligent control program, instantly calculates the path to the target.

Twelve firefighting drones circling in the air while changing their flight trajectory.

I saw that the twelve firefighting drones were divided into two groups when adjusting the direction, arranged in a straight line, and lowered the height at the same time.

Then, two groups of drones, one in front of the other, flew towards the target.

Tang Rui clasped his hands and quietly looked at the picture on the screen.

These firefighting drones do not need him to control.

Just set your goals.

Choose between airplane mode or attack mode.

The system automatically calculates the flight path.

There is no need for manual operation at all.

Otherwise.

No matter how fast his hands were, he couldn't operate twelve drones by himself.

On the way to the flight.

When these firefighting drones scan for people and vehicles in front of them, they will adjust their flight path to avoid people and vehicles.

Tang Rui watched the flight trajectory tracking and draw the route, and nodded with satisfaction.

The problem of coordination of multiple UAVs has always been a big problem.

The multi-machine linkage intelligent program strengthened by the system panel not only solves the problems of data transmission and sharing and task allocation, but also solves the problem of collaboration.

Just now, while avoiding vehicle obstacles, twelve drones adjusted their direction and slowed down at the same time.

During the closest time the two drones were close, there was only a 20 cm spacing.

This kind of synergy is not something that can be done manually.

Soon.

Twelve firefighting drones dodged the obstacles, flew over the target, and then began to circle at a low altitude.

Tang Rui stretched out his hand and marked a point at the location of the villa.

This time, he chose the mode of annihilation.

With the order given.

Twelve firefighting drones climbed at the same time, and when they climbed to an altitude of 100 meters, they began to fly towards the villa, and at the same time the system began to scan and search for targets.

Vehicles and pedestrians on the road are all marked.

At this time, as long as Tang Rui clicks on the screen, confirm the annihilation command.

Then these drones will attack.

But he couldn't have clicked.

Therefore, during the flight of the drone, all the marked targets are marked on the map.

This is a feature of Scout Mode.

However, some of these commands were embedded by him in annihilation mode.

For example, sometimes the target is not completely annihilated, but the number of drones is not enough.

In this case, mark the enemy so that the next time you attack, you can attack them directly.

Soon.

Twelve firefighting drones returned to the sky above the villa and began to hover at a low altitude, waiting for orders.

There are no more orders.

All the systems are normal, and all the functions are fine.

As for the real "extinguishing" effect.

He couldn't experiment.

Therefore, this test flight is over.

Landing......

Suck!

At this time, Tang Rui thought about it, he did not arrange to land the trawl.

Glancing at the cruise time on the screen, there were just over twenty minutes left.

He sprang to his feet.

Rip the sheets off the bed and run to the yard.

Got to the yard.

He took out four poles, tied them to the four corners of the sheets, and when they were secured, he stuck them in the grass.

I'm sure there's nothing wrong with that.

He ran back to his room and controlled the firefighting drone to fly over his villa.

Then mark the sheets in the yard and finally click to land.

Twelve drones circled around the villa twice, and after scanning the surrounding terrain and obstacles, they began to adjust their flight trajectory.

I saw a firefighting drone swooping from the sky, coming to the gate of the villa, and then pulling it up one by one.

With gravity and drag, counteract the speed.

At the same time the propeller stopped working.

In the end, the firefighting drone, after drawing a U-shaped curve, fell from more than three meters in the air and landed accurately on the sheets.

After the firefighter drone landed, the second firefighter drone began to repeat the action.

And Tang Rui at this time.

Next to the sheets, he quickly took away the firefighting drone that fell on it.

After half ringing.

He was relieved when the last firefighting drone landed accurately on the sheets.

It's okay, it's normal together.

In the beginning, the landing was very accurate.

But on the penultimate flight, I almost fell to the ground.

Tang Rui was taken aback.

Aluminum alloy is not fall-resistant.

smashed directly on the ground from a height of more than three meters, and it was not enough to break the bones, but if you fell half-crippled, you must not have run.

He glanced at the system panel of the drone, and was 230 years away from upgrading.

Fly almost one more time and you'll be able to level up.

But this thing doesn't pursue upgrades.

If you don't upgrade, it doesn't mean much.

At most, it looks good.

The equipment is still those equipment, it is impossible for him to strengthen.

Upstairs.

Remove the transmitter from the balcony.

Then plug all the firefighting drones into the launch canister and start charging.

Then remove the sheets.

This sheet is considered waste.

In several places, they were marked by metal burrs on the body.

Just put it in the washing machine and wash it, it will definitely break it.

But it just so happened that it was kept as a landing trawl for firefighting drones.

Busy for a long time.

Pack everything up.

He went back to his room, put on his subliminal learning device, and lay down in bed to sleep.

In a dream.

The theoretical knowledge of various rocket engines slowly flowed into his brain.

He had already finished all the previous books on mechanical design and circuits.

Originally, he thought about whether to learn something about microelectronics.

But he eventually gave up.

Although he has a golden finger, he can't study chips across industries.

Others don't believe it, either.

Even if he studies tanks, exoskeletons, and even rockets and spaceships, it is more reliable than him to engage in chips.

So, lithography machine or something, he's not going to touch it.

Unless he develops, he goes into interstellar travel.

At that time, if the domestic lithography machine was not good, it would not be too late for him to make another move.

Learn some knowledge related to his major first, and then talk about the rest.

And the rocket engine is something he has to figure out.

It's not for fire extinguishers.

Someone has already done that thing, and they have all been sold to big dog owners.

The firing range is 300 km, and the counterweight cannot be reduced.

After reducing the counterweight, there is no warranty, no after-sales, and there is still a range error of 1700 km.

Tang Rui learned this in order to directly get on the horse and change the cycle engine when he was engaged in a real fighter in the future.

This kind of engine is the black technology.
