"Photokinetic stealth drone?"

"I didn't do a stealth design this time!"

"Wait! Could it be this ......?"

Looking at the name and remarks of the drone, Chen Yi seemed to think of something.

In the past, a laser pointer was turned out next to it, and when the button was pressed, a green laser beam was illuminated.

The green light shines on other objects, and the reflection is dazzling.

But when the movement hits the surface of the drone, the light suddenly dims.

The dazzling green light turned into a hazy and dim glow......

"Whew!"

"Sure enough, this is it!"

Chen Yi's hands trembled twice.

I've been thinking about how to improve solar panels.

As a result, he almost forgot the nature of the sun's rays.

- Electromagnetic waves.

Sunlight is an electromagnetic wave.

Lasers are electromagnetic waves.

Radar detection waves are also electromagnetic waves.

The spectrum of sunlight, in addition to the usual visible light.

It also contains other invisible ultraviolet rays, infrared rays, radio waves, microwaves, and even trace amounts of X-rays and gamma rays.

These rays of light across all spectrums combine to form sunlight in the popular sense.

Since the current solar panels convert more than 50 percent of sunlight, this has destroyed the reflection of radar waves.

The radar detection system performs echo detection, and at most detects a cloud of clutter, which does not show a clear signal at all.

This situation, which is equivalent to Chen Yi's drone, has achieved radar invisibility.

Rather, it's still standard full-spectrum optical invisibility.

Stealth is carried out not by the special stealth design of the fuselage, which reduces the radar reflection cross-section.

If you adjust the properties, the GaN solar panels are upgraded to a solar cell film with a conversion rate of 84.6 percent, optical quantum technology.

Not to mention radar, if you put the drone in front of you, it will look blurry to the naked eye.

Because of the principle that the eye can see, it is through the light that hits the object and then reflects it to the eye.

The retina senses light signals, which are converted into nerve signals and processed by the brain.

But now, 84.6 percent of the light is converted into electricity, and some of the light is absorbed by the surface of the object and turned into heat.

The light that can be reflected back in the end is only a very small fraction of the total light.

It looks like it's just a blur.

"The solar cell film just now, it seems to be quite light and soft, take it to the tailor to make a set of double-layered and double-sided clothes, and go out at night, it will definitely be regarded as a ...... of A Piao"

After figuring out the stealth logic of the drone, Chen Yi refocused his attention on the attributes of the drone.

"This warning sign of energy is a little scary,"

Looking at this hint that the risk of explosion had increased by 10,000 times, Chen Yi stepped back a few meters from a safe distance, his eyes wandering over each attribute, thinking about how to make adjustments.

"In terms of endurance supplements, you need to adjust and upgrade 25 points."

"The requirements for this adjustment are a bit high, and it is difficult to squeeze out so many attributes from other attributes.

"It seems that this time we can only carry out a stacking upgrade."

Chen Yi thought for a while.

It was found that no matter how it was adjusted, it would seriously weaken the core performance of the drone.

There's no way, this only costs a little more, consumes a little more consciousness waves, and chooses to superimpose upgrades.

Anyway, the key technology of the drone now is either designed by himself and mastered, or the technical information has been read.

The impact of not being able to read the information after the superimposed upgrade is not a big problem at all.

"Battery production, which takes several hours, communication and radar modules, which also require superimposed manufacturing."

"The fastest module to be manufactured in this way can only be the avionics module."

Determined the direction of superposition improvement, Chen Yi thought about it.

Colorful light bloomed, enveloping the manta drone in front.

[Avionics: 34.5→1.5]

[Endurance supplement: 44.6→69.6]

[Intensity: 13→21]

[Quality: (16) 21→21]

[Stable: (16) 35→35]

[Speed: (3)12.3~(1.2)3.6→12.3~3.6】

Ten minutes later.

The light dissipated.

The original model drone with a layer of armor has changed.

The armor turned into a mech, fitting perfectly to the carbon fiber body underneath.

At the same time, the solar panel armor turns into a solar cell film that fits the fuselage perfectly.

Attributes such as mass, stability, and speed, which had been originally lost, have also been restored to their true values.

"This motherboard is scrapped."

Chen Yi looked at the solar cell film using optical quantum technology.

Open the body case and unscrew the screws of the motherboard.

Carefully remove the wiring harness that connects the motherboard to communications, radar, hydraulic wheels, battery modules, wing and tail controllers, including the solar cell film, and then take the motherboard out.

Avionics module, nothing else.

The essence is the drone control motherboard + avionics control system.

Motherboard, this is the template of the standard.

The real heart is the avionics control data and systems in it.

And this part of the system and data, Chen Yi has already had a backup.

After taking two high-performance drone control motherboards, Chen Yi connected the recorder and began to burn the underlying code.

After waiting for more than ten minutes, the underlying code was burned.

After checking and making sure that there was no problem, this was connected to the computer again and the complete avionics control program was imported.

But 40 minutes.

Two new high-performance avionics control motherboards have just been released.

Chen Yi took a motherboard, connected the wiring harness, and then installed and fixed it into the drone.

[Avionics: 1.5→34.5]

[Add external function modules, the quantum realm collapses and reorganizes, the follow-up information cannot be read, and the adjustment of the consciousness wave is doubled!] 】

"This time, we will solve the hidden dangers of battery energy, improve the quality attributes, reduce the quality of the drone, and adjust the stability attributes to further improve the aerodynamic layout and internal structure stability of the drone."

Chen Yi glanced at the prompt of doubling the consciousness wave.

Without hesitation, continue to adjust the attributes.

[Avionics: 34.5→1.5]

[Energy: 41.1 (!) ）→49.1】

[Mass: 21→29]

[Steady: 35→43]

The light is gone.

The drone in front of you has become more streamlined, and the overall height has also dropped by 6 centimeters.

The angles, length, width and other parameters of the wings, as well as the curvature of the fuselage surface, have also changed.

"I see, in addition to the adjustment of details, the pneumatic layout should consider the overall situation from an overall perspective.

The previous curvature of the fuselage and the previous wing height will have a conflict of internal friction when flying at high speeds.

An excessively short tail with a sweep angle with the tail can affect the fine balance of the fuselage at supersonic speeds.

Now that the rear wing has been adjusted, this effect has disappeared significantly.

The two work together to further improve stability. ”

Although he could not read the information, he relied on his mastery of aerodynamic layout.

Chen Yi checked the adjusted drone, pondered carefully, and calculated.

However, I found many aerodynamic effects that I didn't know before, and I have a deeper grasp of the aerodynamic layout of the aircraft.

"After the adjustment, the UAV has a lift coefficient of more than 2.57 and a drag coefficient as low as 0.012, which is an aerodynamic improvement, and the overall flight efficiency has increased by 4 points.

The conversion area of solar energy, including the aerodynamic arc of the fuselage, has an area of 3.68 square meters on the back and 3.12 square meters on the belly.

Although the area of the belly of the machine cannot receive solar energy directly.

But 84.6 percent of the metamorphosis conversion rate is through diffuse reflection of air.

This can also get a lot of energy.

Such a drone can convert at least 70 kilowatt-hours of electricity a day when it goes up to the stratosphere. ”

Chen Yi took out a pen and paper to calculate the lift coefficient and drag coefficient of this pneumatic layout.

Then he took out the scanner and scanned the surface area of the drone.

When all the results are calculated.

There was only one thought left in Chen Yi's heart.

Strong!

It's too strong!

It can further improve the aerodynamic performance while increasing the surface area of the drone and increasing the conversion power of the solar cell film.

Replenishing 70 kWh of electricity a day, this is simply an ultra-long-lasting perpetual motion drone in the air.

"Three o'clock in the morning."

"Take this drone to spray the thermal barrier protective layer, add a layer of transparent beryllium oxide ceramic, and complete the final process."

"As expected, I can complete the performance test in the morning, report for the test flight, catch up with the sun, the sun does not set, I will not set, and appreciate the great rivers and mountains of the motherland!"

Chen Yi suppressed the excitement in his heart, dismantled the scrapped control motherboard, replaced it with a new motherboard, and then pulled it to the coating spraying room on the side with a hand forklift.

PS: Ask for follow-up, ask for monthly passes and recommended tickets.
