This civilization is very strong, but the technology tree is a bit crooked

"Photodynamic stealth drone?"

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

"Wait! Could it be this"

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

In the past, a laser pointer was pulled out next to it, and a green laser beam was irradiated by pressing the button.

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

But when the movement irradiated the surface of the drone, the light suddenly dimmed.

Brilliant green light, turning into a hazy dim flickering glow

"call!"

"It really is this!"

Chen Yi shook his hands twice.

Been thinking about how to improve solar panels.

It caused him to almost forget the nature of sunlight.

- Electromagnetic waves.

Sunlight is electromagnetic waves.

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, infrared, radio waves, microwaves, and even trace amounts of x-rays and gamma rays.

The combination of these rays of light of the whole spectrum forms the sunlight in popular sense.

Since the current solar panels have a conversion rate of more than 50% of sunlight, there is also a light concentrating structure that distorts and destroys the light signal.

In this way, when the radar detection system performs echo detection, at most a group of clutter can be detected, and no clear signal can be displayed at all.

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

If the properties are adjusted, the gallium nitride solar panel is upgraded to a solar cell film with a conversion rate of 84.6 percent and photon quantum technology.

At that time, not to mention the radar, if you put the drone in front of you, it will look like a fuzzy and distorted mass of black to the naked eye.

Because of the principle that the eyes can see, this is through the light shining on the object and then reflecting to the eyes.

The light signal is sensed by the retina, and the image is formed after the light signal is converted into a nerve signal and processed by the brain.

Now, 84.6 percent of the light is converted into electrical energy, and part of the light is absorbed by the surface of the object and turned into heat.

Finally, the light that can be reflected back is converged by the light-gathering structure, and the incident angle and reflection angle of the light are distorted indefinitely, even if it is reflected back, all information is lost.

It looks like it is distorted and blurred.

"The solar cell film just now looks very thin and soft. If you use it to tailor a double-layer and double-sided clothes, if you go out at night, you will definitely be regarded as a piao."

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

"This warning sign for energy is a bit scary,"

Seeing the reminder that the risk of explosion has increased by ten thousand times, Chen Yi stepped back a few meters at a safe distance, wandering his eyes on each attribute, thinking about how to make adjustments.

"The attributes of battery life supplement need to be adjusted and upgraded by 25 points."

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

"It seems that this time only superimposed upgrades can be performed."

Chen Yi thought for a while.

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

There is no way, this only costs a little more cost, a little more consciousness wave, and chooses to superimpose and upgrade.

Anyway, the key technology of drones is either designed by himself and mastered, or he has read the technical information.

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

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

"The fastest manufactured module can only be the avionics module."

After confirming the direction of superimposed improvement, Chen Yi had a thought.

Colorful lights bloomed, covering the stingray drone in front.

[Avionics: 34.5→1.5]

【Supplementary battery life: 44.6→69.6】

[Strength: 13→21]

Ten minutes later.

The light faded.

The aircraft model drone that was originally covered with a layer of armor has changed its appearance.

The armor becomes the suit, which fits perfectly over the carbon fiber fuselage underneath.

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

Attributes such as quality, stability, and speed that were originally affected are also restored to their original values.

"This motherboard is useless."

Chen Yi opened the case of the fuselage, and looked at the main board of the drone, which looked as if it had been exposed to wind and rain for two and a half years, with a dim and semi-weathered color.

Take out the screwdriver and carefully unscrew the motherboard screws.

Carefully remove the wiring harness connecting the main board to the communication, radar, hydraulic wheel set, battery module, wing and tail controller, including the solar cell film, and then take out the main board.

Avionics module, nothing else.

The essence is UAV control board + avionics control system.

Motherboard, this is the standard template.

The real core is the avionics control data and system.

As for this part of the system and data, Chen Yi already had a backup.

After taking two high-performance drone control boards, Chen Yi connected the burner and started to burn the underlying code.

After waiting for more than ten minutes, the bottom layer code burning is completed.

After checking it and confirming that there is no problem, it was connected to the computer and started to import the complete avionics control program.

But 40 minutes.

Two brand-new high-performance avionics control boards are freshly released.

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

[Avionics: 1.5→34.5]

[Add external functional modules, the quantum field collapses and then reorganizes, the follow-up information cannot be read, and the adjusted consciousness wave is doubled! 】

"This time, we will solve the hidden danger of battery energy, and then improve the quality attribute to reduce the quality of the drone. The rest will adjust the stability attribute to further improve the aerodynamic layout and internal structure stability of the drone."

Chen Yi looked at the reminder that the wave of consciousness had doubled.

Without hesitation, continue to adjust the attributes.

[Avionics: 34.5→1.5]

[Energy: 41.1 (!) → 49.1]

【Quality: 21→29】

【Stability: 35→43】

The light dissipated.

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

The angle of the wing, parameters such as length, width and height, and the curvature of the fuselage surface have also changed one by one.

"It turns out that in addition to adjusting the details of the aerodynamic layout, it is also necessary to consider the overall situation from an overall perspective.

The radian of the fuselage before and the height of the wing before are individually designed very well, but there will be an airflow internal friction when flying at high speed.

Too short empennage and the sweep angle of the empennage will affect the delicate balance of the fuselage at supersonic speed.

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

The combination of the two will further enhance the stability. "

Although it is impossible to read the information, it relies on its own knowledge of aerodynamic layout.

Chen Yi checked the adjusted drone in comparison, pondered carefully, and made some calculations.

On the contrary, I discovered 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 lift coefficient of the UAV exceeds 2.57, and the drag coefficient is as low as 0.012. This kind of aerodynamic improvement improves the overall flight efficiency by 4 points.

The conversion area of ​​solar energy, counting the aerodynamic arc of the fuselage, the area of ​​the back reaches 6.28 square meters, and the area of ​​the belly reaches 5.89 square meters.

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

But with an abnormal conversion rate of 84.6%, a lot of energy can be obtained through the diffuse reflection of the air and the reflection of the clouds.

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

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

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

When all results are calculated OK.

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

powerful!

too strong!

It can actually increase the surface area of ​​the drone and increase the conversion power of the solar cell film while further improving the aerodynamic performance.

Replenishing 70 kWh of electricity a day, this is simply a drone with a long battery life in the air.

"Three in the morning."

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

"Unsurprisingly, the performance test can be completed in the morning, report for the test flight, and travel in time to catch up with the sun. I will never set when the sun never sets. Enjoy the great rivers and mountains of the motherland!"

Chen Yi suppressed the excitement in his heart, removed the scrapped control board, replaced it with a new one, and then used a forklift to pull it to the coating spraying room on one side.
