Chapter 46 Photodynamic stealth drone!
The sun is the nearest star to Blue Star.
Its light and heat are the source of all life on the Blue Star.
Through the core's nuclear fusion effect, 4 million tons of mass per second are completely converted into energy.
In the form of solar radiation, it is spread into the vast space of the universe.
Even if Blue Star can only receive one-billionth of it, at the same time, it will be one-billionth of it.
30% will be reflected by the atmosphere and returned to space, and 23% will be absorbed by the atmosphere.
The remaining 47% has to reach the surface.
But even so, its irradiation power reaches 80 trillion KW.
The energy irradiated per second is equivalent to the energy released by the combustion of 5 million tons of standard coal.
The average power per square meter on the ground reaches 630W to 700W, with an average daily average of more than 5 kilowatt hours.
“With an average of 5 kilowatt hours of solar energy per day, this solar cell film has a conversion rate of 84.6%.”
"In this way, 1 square meter of area can obtain 4.2 kilowatt hours of electricity per day."
"If the drone stays away from the surface, goes beyond the clouds, and enters an altitude of 5,000 meters."
"Without the obstruction of clouds, the electric energy converted by this 1 square meter of fuselage area should be more than 6 kilowatt hours."
"The higher the altitude, the stronger the radiation of sunlight, and the more electrical energy the drone obtains."
"If you leave the troposphere and enter the stratosphere at an altitude of 10,000 meters, the electrical energy converted by 1 square meter should be estimated to reach 8 kilowatt hours."
Chen Yi recalled some of the information parameters of the planet illuminated by sunlight, took out paper and pen, and wrote down the design points of the sun-never-setting drone.
First of all, the aerodynamic layout must be good, which is the foundation.
The weight of the fuselage should be kept as low as possible, which is the core.
Finally, the surface area of ​​the fuselage must be as large as possible, which is the key.
Based on these three elements.
Chen Yi thought for a while and drew the general configuration of the Sun Never Sets drone on the drawing.
This aircraft is 2.8 meters long, the widest part of the wing is 2.5 meters, and the height including the landing gear is 0.54 meters.
It has wide wings, an extended vertical horizontal tail, a streamlined fuselage that conforms to an aerodynamic layout, and an overall flat shape, similar to the shape of a manta ray aircraft.
Determine the shape of the drone.
Chen Yi also based on the fluid equation and the data obtained from the last test flight.
Start to perfect some parameter details of the aerodynamic layout of the fuselage.
For example, the angle of the wing, the curvature of the fuselage, the vertical angle of the tail, the horizontal angle, the balance angle, the width and height, etc.
After a few hours, the design of the aerodynamic layout of the fuselage was completed.
Chen Yi did some rough calculations and came up with the lift coefficient and drag coefficient of this fuselage structure.
"The theoretical lift coefficient reaches 2.38, and the zero-lift drag coefficient of supersonic cruise is as low as 0.028."
“The next step is the material of the fuselage.
This time, a solar cell film is added, and the fuselage is made of three-layer composite materials.
The innermost part uses carbon fiber as the base frame, and in the middle is a layer of solar cell film.
The surface is a layer of transparent beryllium oxide ceramic, which acts as a thermal barrier and physical protection.
The engine also needs further improvement.
In addition to the enlargement of the engine, electric field propulsion replaces combustion to do work. After all, it is different from ordinary combustion engines, and some details also need to be modified.
Because the explosion of ion propulsion is insufficient, the stamping structure of the air intake channel needs to be expanded by 2 percent to reduce the resistance of the air intake.
The combustion chamber is replaced by electric field acceleration. Without combustion expansion, the injection channel behind needs to be reduced by 2.5 percentage points.
The electric field accelerating chamber in the middle also needs to undergo certain growth.”
Passed by Rong Fei and his party.
Chen Yi already has a lot of experience in the structure of large drones and the design of large engines.
Although this Sun Never Sets UAV is no more than 2.8 inches long and 2.5 inches wide, it is far from being called large.
But compared to the drones he designed and manufactured before, which have never exceeded two meters, this is already a big improvement.
It can be said.
This time, in addition to building a drone that never sets.
What's more important is to verify his progress and gains over the past twenty days.
"Finally, the most critical solar cell film."
At eight o'clock in the evening, all module designs were completed.
Chen Yi looked at the solar cell film on the other side.
"Read information!"
Boom! Densely packed information bloomed in my mind.
Chen Yi worked hard to digest this information.
Discover external parameters such as the melting point, viscosity, and toughness of the material.
Others involved the real transformation principles and manufacturing processes, but he found that he was sure of it at first sight but confused at the other.
"These processes and principles should be a kind of quantum technology. Through special quantum processing, the photoelectric effect is enhanced to the extreme, the internal resistance is reduced, and at the same time, microscopic light-concentrating structures are created."
"With this knowledge base, I started to build Dyson balls and play with sophons."
Chen Yi rubbed his swollen head, feeling a little speechless.
"It seems that we can only use II-V gallium nitride compound solar panels as a basis and then adjust and upgrade them."
Chen Yi imported the drawings of the drone into the printer for printing, but he didn't feel too surprised.
Early testing showed that the conversion rate of this solar cell film was 84.6%.
Chen Yi knew that this was most likely a technology that involved a field of knowledge that he did not understand at all and exceeded the limits of the current scientific and technological foundation.
Seeing that the printer was working normally, Chen Yi went down to the first floor.
Come to the back of the warehouse and see the newly expanded laboratory during this period.
Open the laboratory's professional-grade chemical preparation equipment and begin to prepare II-V gallium nitride compound materials.
Originally, Chen Yi did not know these chemical preparation techniques.
But after several virtual studies, and under the professional training of virtual teachers, teaching by words and deeds, and in-depth educational guidance, he has learned to master it.
After the materials are preheated and mixed according to the proportion, the intense chemical reaction causes the liquid to seep out.
Chen Yi wiped away the seeping liquid, then put in the initial seeds and injected the reducing agent. In the following time, he just waited for the compound to grow naturally.
"Done."
Through the equipment observation window, confirm that the reaction growth in the equipment is stable.
Chen Yi took the time to make a new unstable and safe battery.
[Item: Ultra-high energy carbon silicon lithium battery]
[Attributes: Energy x41.1, Safety x10 (-2.2), Strength x19.2]
Three core attributes that remain unpretentious.
Among them, the safety attributes from minus 8.8 → minus 8.4 → minus 7.8 represent the progress of Chen Yi’s manufacturing process.
"Yes, my technology has improved, and I am still a genius."
Chen Yi admired his improved skills, carefully moved the battery to the forklift, and carrying a fire extinguisher in his hand, he carefully walked to the work area on the second floor.
Returning to the workspace, the various components of the drone have been printed.
Chen Yi checked it over, reset the printing of several defective components, and then returned to the first floor.
Dry the prepared solar panels and dry the liquid moisture.
Chen Yi began to manufacture the final product according to the parameter size of the fuselage, slicing, shaping, series connection, splicing, lamination, packaging and other processes.
After scrapping more than a dozen battery films.
One set of upper and lower parts, like the protective armor of the drone, the solar cell module that almost completely fits the fuselage is officially released.
Take solar cell armor, carbon fiber components, engine components, communication, radar, hydraulic wheel sets and other accessories that cost hundreds of thousands of consciousness wave superimposition upgrades, as well as unsafe batteries.
After some assembly.
Soon, a black drone with a shape like a manta fish appeared in front of Chen Yi.
[Item: Light-powered stealth drone]
[Attributes: Energy x41.1(!), Speed ​​x10.3(-3.8), Mass x21(-5), Stability x35(-19), Strength x13, Communication x31.7, Radar photography x36.6, Avionics
x34.5, beautiful x11.8, battery life x44.6]
[Note: This is an ion-propelled stealth aircraft designed with a lot of imagination and using light kinetic energy.
Unfortunately, the instability of the energy source increases the risk of it taking off and exploding ten thousand times.
The added photo kinetic energy kit is too cumbersome and affects speed, stability and quality]
