Chapter 47 70 kWh per day, perpetual motion machine in the air.
"Optical kinetic energy stealth drone?"
"I didn't do any stealth design this time!"
"Wait! Could it be this?"
Looking at the name and remarks of the drone, Chen Yi seemed to have thought of something.
Go over and pull out a laser pointer, press the button, and a green and environmentally friendly laser will shine out.
Green light shines on other objects, and the reflected light is very dazzling.
But when the movement illuminates the surface of the drone, the light suddenly dims.
The dazzling green light turned into a hazy, dim and flickering glow.
"call!"
"It is indeed this!"
Chen Yi's hands shook twice.
Always thinking about how to improve solar panels.
As a result, he almost forgot the nature of sunlight.
——Electromagnetic waves.
Sunlight is electromagnetic waves.
Laser is an electromagnetic wave.
Radar detection waves are also electromagnetic waves.
Among them, the spectrum of sunlight, except for ordinary visible light.
It also contains other invisible ultraviolet rays, infrared rays, radio waves, microwaves, and even trace amounts of x-rays and gamma rays.
The combination of these lights of the entire spectrum forms sunlight in the popular sense.
Since today's solar panels have a conversion rate of more than 50% of sunlight, there are also light concentrating structures that distort and destroy the light signal.
In this way, when the radar detection system performs echo detection, it will detect at most a bunch of clutter and cannot display a clear signal at all.
This situation is equivalent to Chen Yi's drone having achieved radar invisibility.
If the properties are adjusted, the gallium nitride solar panel can be upgraded to a solar cell film with a conversion rate of 84.6% and photon quantum technology.
Let alone radar, if you put the drone in front of you, it will look like a blurry and distorted black mass to the naked eye.
Because the eyes can see visually, this is through light hitting objects and then reflecting back to the eyes.
The retina senses light signals, converts the light signals into neural signals, and the brain processes them to form an image.
Now, 84.6% of the light is converted into electrical energy, and some of the light is absorbed by the surface of the object and turned into heat energy.
Finally, the light that can be reflected back is condensed by the light-condensing structure, and the incident angle and reflection angle of the light are uncertainly distorted. Even if it is reflected back, all information is lost.
It looks like it's distorted and blurry.
"The solar cell film I just used seems to be quite thin and soft. Use it to make a set of double-layered 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 returned his attention to the properties of the drone.
"This warning sign on energy is a bit scary,"
Seeing this reminder that the risk of explosion increased ten thousand times, Chen Yi stepped back a few meters to a safe distance, his eyes wandering over each attribute, thinking about how to make adjustments.
"The battery life supplement attributes 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 we can only carry out superimposed upgrades."
Chen Yi thought for a while.
It was found that no matter how you adjust it, it will seriously weaken the core performance of the drone.
There is no other way, this can only cost a little more, consume a little more consciousness waves, and choose to superimpose and upgrade.
Anyway, the key technology of drones is either designed by himself and already mastered, or he has read the technical information.
The impact of not being able to read information after the superimposed upgrade is not a big deal at all.
"Battery production, which takes several hours, and communication and radar modules, which also require additive manufacturing."
"The fastest module to manufacture can only be the avionics module."
After determining the direction of superimposed improvement, Chen Yi had an idea in his mind.
Colorful lights bloomed, covering the manta ray drone in front.
【Aviation:34.5→1.5】
[Battery life supplement: 44.6→69.6]
【Strength:13→21】
Ten minutes later.
The light dispersed.
The model aircraft drone that was originally covered in a layer of armor has changed its appearance.
The armor becomes a suit, perfectly fitting the carbon fiber body underneath.
At the same time, the solar panel armor turns into a solar cell film that perfectly fits the body.
The originally affected attributes such as quality, stability, speed, etc. also return to their original values.
"This motherboard is useless."
Chen Yi opened the casing of the fuselage and looked at the drone's motherboard, which looked like it had been exposed to wind and rain for two and a half years, with a dull color and a semi-weathered appearance.
Take out the screwdriver and carefully unscrew the motherboard screws.
Carefully remove the wiring harness that connects the main board to communications, radar, hydraulic wheels, battery modules, wing and tail controllers, including the solar cell film, and then take out the main board.
Avionics module, nothing else.
The essence is the drone control motherboard + avionics control system.
Motherboard, this is the standard template.
The real core is the avionics control data and systems within it.
As for 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 burner and began to burn the underlying code.
After waiting for more than ten minutes, the underlying code burning was completed.
After checking to make sure there was nothing wrong, I connected it to the computer and started importing the complete avionics control program.
Only 40 minutes.
Two brand new high-performance avionics control motherboards are just released.
Chen Yi took a motherboard, connected the wiring harness, and installed it into the drone.
[Aviation:1.5→34.5]
[Add external functional modules, the quantum field collapses and reorganizes, subsequent information cannot be read, and the adjustment consciousness wave is doubled!]
"This time we will solve the hidden dangers of battery energy, then improve the quality attributes and reduce the mass of the drone. The rest is to adjust the stability attributes and further improve the aerodynamic layout and internal structural stability of the drone."
Chen Yi looked at the prompt that the wave of consciousness doubled.
Without hesitation, continue adjusting attributes.
【Aviation:34.5→1.5】
【Energy:41.1(!)→49.1】
【Quality:21→29】
【Stable:35→43】
The light dissipates.
The drone in front of me has become more streamlined, and its overall height has also dropped by 6 centimeters.
The angle of the wings, length, width and height and other parameters, as well as 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, we must also consider the overall situation from an overall perspective.
The previous fuselage curvature and the previous wing height were individually designed very well, but internal airflow friction would occur during high-speed flight.
A tail that is too short and the sweep angle of the tail will affect the delicate balance of the fuselage at supersonic speeds.
Now that the rear wing has been adjusted, this effect has obviously disappeared.
The combination of the two further improves stability."
Although he cannot read information, he relies on his knowledge of aerodynamic layout.
Chen Yi checked the adjusted drone, thought about it carefully, and made some calculations.
On the contrary, I discovered many aerodynamic effects that I didn't know before, and I gained a deeper understanding 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. Such aerodynamic improvements increase the overall flight efficiency by 4 points.
The solar energy conversion area, including the aerodynamic curvature of the fuselage, reaches 6.28 square meters on the back and 5.89 square meters on the belly.
Although the belly area of ​​the aircraft cannot directly receive solar energy.
But the metamorphosis conversion rate of 84.6% can also obtain a lot of energy through diffuse reflection of the air and reflection of clouds.
When such a drone goes to the stratosphere, it 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 and determined.
There was only one thought left in Chen Yi's mind.
powerful!
too strong!
It can actually further improve the aerodynamic performance, increase the surface area of ​​the drone, and increase the conversion power of the solar cell film.
Replenishing 70 kilowatt hours of electricity a day, this is simply a long-lasting aerial drone.
"Three o'clock in the morning."
"Take the drone to spray a thermal barrier protective layer, add a layer of transparent beryllium oxide ceramics, and complete the final process."
"As expected, I can complete the performance test in the morning, prepare for the test flight, and catch up with the sun. I will not set until the sun sets, and enjoy the great rivers and mountains of the motherland!"
Chen Yi suppressed his excitement, removed the scrapped control motherboard, replaced it with a new one, and then used a forklift to pull it to the coating spray room on one side.
