A big country of aerospace with black technology

"Maybe they rely on magic?"

Lidya Su said something confused.

"If we create a rise around the sword, we might be able to solve this problem."

Zhang Xingyang said after his imagination was opened.

Su Xiao was speechless: "Then why don't you just build a flying car or a flying house?"

"Don't you think Feijian is handsome?"

The researcher who just got off the sword also spoke after hearing the conversation between the two.

Zhang Xingyang thought for a moment: "It's not impossible to fly a car."

"However, the power of the current lift fan is still very limited, and it is probably too heavy to carry it."

In order to be able to fly the flying sword with a mass of less than 200 kilograms.

Zhang Xingyang designed and manufactured more than a dozen high-power electric lift fans.

Their total power reaches 240 kilowatts.

Equivalent to 340 horsepower.

Enough to drive three ordinary family cars.

But when applied to a flying sword, it can only lift people slightly less than half a meter off the ground.

In fact, if you want to fly high, it’s not impossible.

However, the form of the flying sword itself is very dangerous when flying high.

If you are not careful, you will fall directly to death.

So Zhang Xingyang made certain restrictions.

When the gravity sensor senses a human being.

The height limiter will activate to limit the height of the flying sword to less than half a meter.

In fact, it is easy to fall from a height of half a meter.

Because of the airflow during flight, it is easy for people on the flying sword to lose their balance.

In the experience just now, a few people lost their footing during the flight.

He fell directly from the sword.

Fortunately, the sword didn't fly very high or very fast.

Even the most severely injured.

It's just a slight contusion of the soft tissue.

However, even wrestling cannot resist the charm of Feijian on everyone.

"How long can the energy of the flying sword be maintained?" Su Xiao asked, looking at everyone who was having a great time.

Zhang Xingyang looked at everyone who was having a great time: "As long as he doesn't break down, he can keep flying."

"What power did you use? So powerful?"

Lidya Su said in surprise.

"electricity."

Zhang Xingyang said: "It is connected to the high-power wireless power transmission device in the experimental center."

"So that's it." Lidya Su nodded.

Su Xiao didn't know much about the wireless power transmission project, he just knew that this project existed.

But I didn’t expect that wireless power transmission could actually produce such a thing.

"If that's the case, wouldn't we be able to create an aircraft that keeps flying in the sky?" The researcher on the side said with some surprise after hearing this.

Flying sword, according to Zhang Xingyang.

It is a very aerodynamic aircraft in itself.

Since it can last indefinitely.

There is no reason why a more aerodynamic drone cannot do this.

"It's more difficult."

Zhang Xingyang is not too keen on the unlimited endurance drone he said.

"Microwave power transmission is directional energy transmission.

The flying speed of drones is too fast, making it difficult to ensure real-time transmission of energy. "

Zhang Xingyang pointed at the flying sword flying in the field:

"Its range of motion is actually not too large, and it cannot exceed this experimental field."

"If it flies out of this area, it will immediately lose power due to loss of energy."

"It has no energy system itself, and relies entirely on the wireless power transmission device in the experimental center to transmit electrical energy."

Zhang Xingyang pointed to the wireless power transmission device in the distance and said.

After listening, everyone present fell into silence.

This way.

This technology doesn't seem to be that useful.

The role of directional transmission is much smaller.

"Actually, it's not necessarily completely impossible."

At this time, a researcher wearing black-rimmed glasses next to him suddenly had an idea and said.

"Although we cannot create a drone with wireless endurance, we can create a drone airport."

No one understood much after listening.

The man with glasses made an analogy: "I wonder if you know the Sky City in the Western Fantasy Magic Story?"

"We can continue this process to create a large drone mothership."

"The drone itself has a limited battery life, but with a mothership, it can also have wireless battery life."

"Drones can replenish energy on the mother ship."

Only then did everyone understand what he meant.

"This seems to be true." Zhang Xingyang thought for a while and said.

The position of the drone mothership is definitely not moving in real time, but fixed in one place for a long time.

In this way, the wireless power transmission device can directly transmit power to the drone mothership.

The mothership then replenishes energy to the carrier-based drone.

"It has certain feasibility."

"Then do you want to give it a try?"

"Try building one?"

Everyone's eyes were basically focused on Zhang Xingyang.

In the presence, only he can decide whether to carry out this research.

"We can build a verification aircraft first to test the waters."

Zhang Xingyang nodded and agreed with their ideas.

In fact, the drone carrier itself is a very large drone.

In terms of technical difficulty.

It's not even as good as the flying sword Zhang Xingyang just made.

Because the flying sword is too small, the load capacity is very strict.

Basically challenging the limits in every aspect.

Since Zhang Xingyang agreed to carry out research on drone motherships.

Several people took advantage of the situation and started discussing the drone mothership.

“What form of motivation are we going to use?”

The first question that comes to mind is the issue of motivation.

Is it using a propeller or a lift fan?

As for jet engines, they are no longer an option.

Because their energy source obviously uses electric energy.

With electric drive, the choice of power is more limited.

The advantage of propellers is that they have sufficient power.

But not smart enough.

If the drone mothership needs to adjust its direction, it will be more troublesome.

The lift fan is slightly less powerful.

If you want to achieve the same lift, the speed of the lift fan must be much smaller.

However, the size of the lift fan can be made smaller.

Convenient for direction adjustment.

After a more intense discussion.

Everyone unanimously agreed to use propellers as the main solution and small lift fans as the supplement.

Soon, everyone discussed a simple drone mothership design plan.

It is expected to use six large propellers as the main power source of the drone mothership.

Although it is called a drone mothership, after everyone’s discussion.

Everyone quickly gave up on the traditional aircraft carrier appearance design.

Because the mothership flies in the air, there is no need for a conventional flight deck at all.

Even after discussion, everyone even gave up on the hangar.

Drone mothership, although it is called a mothership.

But its function is more like a drone charging pile.

It is not needed at all to perform issues such as take-off and storage of the drone.

The drone is driven by electricity and flies with propellers.

It uses high-energy batteries and a set of miniature wireless power transmission devices inside.

When the drone's power reaches the warning level, it will reach the location of the drone mothership and recharge itself.

It's not even needed for landing.

You only need to reach the predetermined position around the mothership.

"This also has the benefit of greatly increasing the drone's operating time."

Zhang Xingyang said: "If we use the method of returning to the mothership to replenish power, it will have high requirements on the equipment inside the mothership."

——

Because the configuration of the mothership is relatively simple.

So in less than a month, the manufacturing work was completed.

If it weren't for the aerodynamics of the six-propeller drone itself, it would be a bit complicated.

It is estimated that it will take one or two weeks to complete the manufacturing work.

"This thing is said to be a drone mothership, but in fact it is just a wireless power transmission device with several pairs of propellers and lift fans added to it."

Zhang Xingyang commented after it was completed.

"But the idea itself still has great value."

The mothership looks a bit strange.

It's like a slightly convex regular hexagon.

An arm extends from each point of the hexagon.

On the arm is a huge propeller.

"The designed operating power of the mothership is 4,500 kilowatts, which can supply 18 heavy-duty propeller drones for charging at the same time."

Su Xiao was introducing Zhang Xingyang on the side.

"Without taking off with a drone, the mass is 76 tons."

"The internal battery pack can allow it to fly for about an hour."

"The current mothership does not carry any weapons systems."

After Zhang Xingyang took a few glances, he felt that this thing was quite handsome.

"Get ready to start testing."

The tractor slowly pulled the huge drone mothership out of the manufacturing workshop.

And prepare to pull it to the experimental take-off area.

After everything is ready.

Six huge electric-driven propellers began to run crazily.

A violent air current comparable to a Category 8 gale.

began to roar within the test site.

The dust on the experimental site even formed a whirlwind.

It was almost difficult for the people on the side to open their eyes.

There were no abnormalities during takeoff.

The propeller soon drove the drone carrier weighing dozens of tons into the sky.

"Preparing to turn on lift fans 1 and 6."

In the control room of the experimental area, everyone is busy nervously and orderly.

The planned arrival position of the mothership is about two kilometers away from the take-off position.

The lift fan will assist the mothership in maintaining its posture during this process.

Make sure it doesn't crash due to instability.

The two propeller arms at diagonal positions began to slowly change their orientation.

From originally parallel to the ground, it gradually turned to perpendicular to the ground.

Provide a forward thrust to the mothership.

A distance of two kilometers is not that far for an aircraft.

It can even be said to be very short.

Even the toy flying sword designed by Zhang Xingyang before can reach a speed of nearly 40 meters per second.

The distance of two kilometers can be reached in just one minute.

The movement speed of the drone mothership is slower.

However, it took more than two minutes to reach the predetermined position of wireless power transmission.

Here, it will receive wireless energy supply from wireless power transmission devices.

"It's a pity that we only have one power-generating satellite now. Otherwise, with our current positioning accuracy, we would be able to provide real-time power supply to the drone mothership from space."

Zhang Xingyang said after sighing.

The microwave positioning accuracy of power generation satellites can now reach the level of ten centimeters.

The positioning frequency can reach more than ten times per second.

"Isn't the second power-generating satellite about to be launched next month?"

"It won't be long before we have something to use."

Lidya Su comforted from the side.

Electric satellites are not built very quickly.

Currently their production capacity has not reached maximum.

It took more than a month to build the second power satellite.

"The second satellite will be used to provide power to the western region, but we can't count on it for the time being."

Zhang Xingyang shook his head and said.

"Let's see if the drone mothership can play its role."

The drone mothership, which is nearly 30 meters long, looks like a dark cloud floating in the sky.

At this time, its height is not very high.

A small black dot can be seen with the naked eye.

"Turn on the shipboard wireless power transmission system."

Zhang Xingyang issued the first order.

"Drones prepare for approach."

In the ground experiment area, they began to fly the simple propeller drone they made.

The structure of the drone is also relatively simple.

It is mainly used to test the wireless power transmission performance of the drone mothership.

So there aren't too many instruments inside.

There are only some simple electronic equipment and the most critical wireless power transmission receiving end equipment.

"The drone is establishing a connection."

Everyone in the control room is looking forward to it.

Look at the progress bar running on the big screen.

"The connection was established successfully and the drone is charging."

In the control room, everyone became happy.

Although this technology is currently unremarkable.

But if you think about it for a moment, you can imagine its huge application prospects.

The first thing that comes to mind is naturally the military aspect.

The unlimited endurance drone can be used as an ultra-long-range reconnaissance drone to perform reconnaissance missions.

It can also carry missiles, rockets, etc. to attack ground, air, and water targets.

This is just one aspect.

The mothership itself can also carry a certain amount of missiles, cruise bombs, and laser weapons.

Not to mention the civilian aspect.

Whether it is used for forest patrol and fire prevention.

Or power line inquiry.

Or it may be weather reconnaissance, etc.

can all play a significant role.

"We are currently only able to complete the drone mothership, but we will wait until we have a more powerful power unit."

"We might even develop a space carrier!"

For everyone at this time, aircraft carriers are already a luxury.

Not to mention the space carrier in science fiction.

But now that they can develop a drone mothership.

It seems that completing the space carrier will not be a problem in the future.

Lidya Su thought in her heart.

Although this may seem a bit science fiction to others.

But it was Zhang Xingyang who said this.

Since Su Xiao met him ten years ago, she has witnessed many miracles he created.

So Su Xiao believes it.

I can see the day when I can build a space carrier!

And that day is certainly not too far away! (End of chapter)
