It's about four o'clock in the morning.
Chen Yi completed the final spraying process.
This is a layer of 0.34mm beryllium oxide ceramic.
With the good high-temperature resistance of ceramic materials, drones can easily isolate the temperature of supersonic thermal barriers.
At the same time, the transparent and thin beryllium oxide will not affect the absorption of sunlight by the solar cell film.
"The high-temperature performance of solar cell thin films is much stronger than that of carbon fiber material resins."
"This time the thermal barrier protective coating has been reduced by 0.28 millimeters."
Chen Yi looked at the new drone, which took more than ten hours to build from three o'clock in the afternoon to the next morning, with a hint of joy in his eyes.
[Item: Beyond Battery Life—Photodynamic Ghost Drone!]
[Attributes: Energy x49.1, Speed ​​x10.3, Quality x29, Stability x43, Strength x21, Communication x31.7, Radar photography x36.6, Avionics x34.5, Beauty x11.8, Battery life x69.6]
[Note: This is an unimaginable drone with a beyond endurance. Its energy does not come from the earth's surface, but from the blazing sun 150 million kilometers away.
With an average battery life of more than 70 kWh per day for ten hours, as long as the speed and consumption are slightly controlled, it can become an almost permanent aerial fortress.
Of course, the light conversion rate, which nearly reaches the physical limit of the material, combined with the light-concentrating structure, arbitrarily distorts the incident reflection angle of the light.
This gives it the function of optical invisibility, which can hide most of its own figure. Whether it is detected by radar or observed by the human eye, it is as blurry as a ghost]
"Really perverted."
Chen Yi looked at the notes and comments on the drone and took off his immersive AR glasses, which were sunglasses today.
Original clear drone.
Suddenly it became blurry and flickered.
The overall feeling is like a mosaic, constantly flickering and shaking, completely losing all the original details.
It is conceivable
Such a drone can even be detected by radar.
This will also be filtered naturally as environmental clutter, and no signal will be found at all.
After all, the radar detection system is not a veteran of artificial intelligence, and it is far from mastering the ultra-high level of uncoded in the mind.
"In the future, when I have more drones, I will build a museum to store every drone I have designed over the years."
"From low altitude to high altitude to space, from the speed of sound to supersonic speed to sub-light speed, from planet to interstellar to the universe. Don't let any one go, want them all, have them all!"
Chen Yi put on the AR glasses again and carried out the test while holding the drone.
After a series of tests, Chen Yi determined the basic parameters of the drone.
Thanks to the flattened stingray shape and some improved quality attributes.
After spraying the thermal barrier protective coating, add a fully loaded battery and full xenon propellant.
The total weight of the drone is only 42.8 kilograms, which is less than 3 kilograms heavier than the previous ion-propelled drone.
If it is thrown away and raised a little, the battery weight reaches 18 kilograms.
This time the fuselage is slightly lighter than the fuselage of the previous drone.
The performance of the engine has become larger and the structure has been optimized and improved. The comprehensive thrust has increased by 23% compared with the ion thruster of the previous drone, and the energy efficiency has increased by 6.3%.
The parameters of the battery, because the energy properties have increased to 49.1, are approaching the limit of carbon-silicon lithium batteries.
The energy density has exceeded 5900Wh/KG and reached 5980Wh/KG.
The 18kg battery has a total capacity of an astonishing 107kw·h.
Coupled with a stronger aerodynamic layout, flight efficiency has increased by 4 percentage points. The flat-designed body of the Manta Ray is more suitable for high-altitude gliding.
Chen Yi made a rough estimate.
The efficiency of the aerodynamic layout has been improved, the efficiency of the engine has been improved, and the battery capacity has been improved.
Based on the comprehensive calculation of 30% low speed, 30% subsonic speed, and the remaining 40% supersonic speed.
This time the drone has a battery life of over 4,000 kilometers easily.
Combined with unpowered gliding flight, the overall battery life is doubled by seven to eight times, and it can exceed 20,000 kilometers without any problem.
Even if you fly at supersonic speeds all the way and occasionally do some supersonic speed racing, the battery life is about 900 to 1,300 kilometers.
If you combine gliding flight with charging and replenishing the solar cell film, the battery life will further increase, and circling the earth will not be a dream at all.
Even if it lands in the end.
It’s not that you can’t continue flying, it’s that your energy can’t stand it.
What!
Will the sun set?
According to Blue Star's rotation speed of 466 meters per second, if it is fully charged, the supersonic jet will be able to catch up with the speed of the setting sun in minutes. Then it will glide to charge, then jet to catch up with the sun, and then glide again.
After confirming the performance of this latest Sun Never Sets drone, Chen Yi took out a multi-copter that he used for test flights before when he was operating drones.
Multicopter.
That is, a drone with multiple axes united together, each with a propeller.
All models of DJI, a well-known company in the industry, are multi-copter aircraft like this.
Chen Yi took apart the casing of the multi-copter, replaced the communication module inside, and replaced the battery with a silicon-carbon lithium battery.
Then adjust and optimize the structure, upgrade the avionics program and stability, and finally install the positioning chip.
Less than half an hour.
An aerial signal relay drone is newly released.
Compared with previous lunar landing drones, fixed-wing model aircraft were used as signal relays.
This multi-copter aircraft, which can hover in the air and is more durable, is undoubtedly more suitable as a signal relay.
"Set off!"
Looking to the east, fish belly white has begun to appear.
Chen Yi felt that he was in good condition after staying up late to cultivate immortality this time, and he didn't bother to rest when he was in a good mood.
He took out his cell phone and dialed the air traffic control bureau's reporting number.
"Hello, this is air traffic control 0A987, what do you want?"
The call was connected in less than three seconds, and a standard Mandarin female voice came from inside.
"Hello, the drone has applied for test flight, number 0A01, number 0A02."
Listening to the familiar voice on the phone, Chen Yi thought for a while but couldn't remember who it was, then ignored it and told his situation.
"Number 0A01"
On the other end of the phone.
When Lin Xiaobei heard this number, he looked stunned for a moment, then took a deep breath and answered professionally.
"Hello, please wait a moment, I will transfer you to the Air Force Management Center and the Space Administration."
"."
Now, it was Chen Yi's turn to not be calm.
Is it such a big fight?
The opening is the Air Force Management Center and the Space Administration.
"Well, don't bother me. I've learned to keep a low profile and won't fly to the moon this time."
At this time, Chen Yi finally remembered the identity of the other party.
The air traffic control operator I met during my last lunar landing test flight report.
"Okay, could you please tell me the area and route destination of this test flight?"
Lin Xiaobei hesitated and began to record the areas and routes that Chen Yi wanted to apply for a test flight.
"Penghai took off, longitude and latitude E114,05,51.17, N22,38,18.79.
First lift off vertically, cross the clouds, enter the high-altitude stratosphere, and then glide westward.
Passing through Guangxi Province and Yunnan Province, entering the Hengduan Mountains and the Himalayas. The destination is Mount Everest."
Chen Yi thought for a while and told his plan for this test flight.
If you want to verify the performance of the Sun Never Sets drone, you can only fly from east to west and in front of the sun.
Over there on the phone.
Lin Xiaobei was dumbfounded.
She knew that she shouldn't believe that Chen Yi had learned to lie low-key.
How can a guy who can live broadcast of sprinting into space, live broadcast of landing on the moon, and be given special attention by his superiors keep a low profile?
There was silence for a while.
Lin Xiaobei's tone had a hint of despair, and he answered calmly and professionally.
"Hello, please wait a moment. According to the route you applied for, I will transfer you to the Air Force Management Center."
Chapter completed!
