Chapter 45 Using Sheets as a Trawl
30 meters low altitude.

The twelve firefighting drones hovered quietly like ghosts.

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

On this cloudy night.

Except for night vision goggles, it is simply invisible to the naked eye.

Even if you can hear voices.

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

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

Then select the drone and click the covert infiltration mode.

woo woo woo...

After receiving the order.

The photoelectric systems of twelve firefighting drones started working.

Ground scanning system.

Laser ranging system.

Optical detection system.

Infrared detection system.

These devices distributed on different drones 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 fire-fighting drones circling in the sky change their flight trajectories at the same time.

I saw that the twelve fire-fighting drones were divided into two groups after adjusting the direction, and they were arranged in a line, and the height was lowered at the same time.

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

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

These fire-fighting drones don't need him to control them.

Just set your goals.

Choose flight mode or attack mode.

The system will automatically calculate the flight path.

No manual operation is required at all.

if not.

No matter how fast he was, he couldn't operate twelve drones by himself.

en route.

When these fire-fighting drones scan people and vehicles in front of them, they will adjust their flight paths to avoid people and vehicles.

Tang Rui watched the flight track and traced out the route, and nodded in satisfaction.

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

The enhanced multi-machine linkage intelligent program of the system panel not only solves the problems of data transmission sharing and task assignment, but also solves the problem of coordination.

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

During the period when the two drones were closest, there was only a distance of 20 centimeters.

This kind of synergy cannot be achieved by manual operation.

soon.

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

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

This time, he chose the annihilation mode.

Following the order.

Twelve fire-fighting drones climbed up at the same time. After climbing to a height of [-] meters, they began to fly towards the villa. 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 taps the screen to confirm the annihilation command.

Then these drones will attack.

But it is impossible for him to click.

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

This is a feature of Scout Mode.

However, some of the instructions were embedded in the annihilation mode by him.

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

In this case, mark the enemies, and the next time you launch an attack, you can directly attack these targets.

soon.

The twelve fire-fighting drones returned to the sky above the villa again, and began to circle at low altitude, waiting for orders.

There are no more orders.

All systems are normal and all functions are fine.

As for the real "fire extinguishing" effect.

He couldn't experiment either.

Therefore, this test flight is over.

landing……

Suck!
Only then did Tang Rui think about it. He didn't arrange to land the trawl.

Glancing at the cruising time on the screen, there are only more than 20 minutes left.

He got up quickly.

Pull off the sheet on the bed and run to the yard.

to the yard.

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

Make sure there's nothing wrong with it.

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

Then mark the sheets in the yard and finally hit land.

Twelve drones circled the villa twice, scanned the surrounding terrain and obstacles, and began to adjust the flight trajectory.

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

Use gravity and drag to counteract speed.

At the same time the propeller stopped working.

In the end, the fire-fighting drone, after drawing a U-shaped curve, fell from a height of more than three meters and landed precisely on the bed sheet.

After the fire-fighting drone landed, the second fire-fighting drone began to repeat this action.

And Tang Rui at this time.

Beside the bed sheet, he quickly took away the fire-fighting drone that fell on it.

After half a sound.

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

Fortunately, we are normal together.

In the beginning, the landing was accurate.

But in the penultimate frame, he almost fell to the ground.

Tang Rui was taken aback.

Aluminum alloy is not resistant to falling.

It fell directly on the ground from a height of more than three meters, and it would not have been smashed to pieces, but it must have not escaped if it was half disabled.

He glanced at the drone's system panel, and it was 230 experience points away from the upgrade.

Almost one more flight to upgrade.

But this thing does not pursue upgrades.

It doesn't make much sense to upgrade or not.

Mostly it looks better.

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

Go upstairs.

Take down the transmitter on the balcony.

Then insert all the firefighting drones into the launch tube and start charging.

Then remove the sheet.

This bed sheet is useless.

Several places were marked by metal burrs on the machine body.

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

But just right, keep it as a landing trawl for the firefighting drone.

Busy for a long time.

Get everything packed.

He just returned to the room, put on the subliminal learning device, and lay down on the bed to sleep.

in a dream.

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

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

Originally, he thought about whether he should learn some knowledge about microelectronics.

But he finally gave up.

Although he has golden fingers, he can't research chips across industries.

Others don't believe it either.

Even if he studies tanks, exoskeletons, or even rockets and spaceships, it is more reliable than his chips.

Therefore, he is not going to touch the lithography machine or anything.

Unless he develops and enters interstellar travel.

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

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

And the rocket engine was something he had to figure out.

It's not for fire extinguishing bombs.

Someone has already made that thing, and it's all sold to big dogs.

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

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

Tang Rui learned this so that when he was engaged in real fighter jets, he would directly mount a variable-cycle engine.

This engine is black technology.
