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

It was past four in the morning.

Chen Yi completes the final spraying process.

This is a layer of 0.34 mm beryllium oxide ceramic.

With the good high temperature resistance of ceramic materials, drones can easily insulate the temperature of the supersonic thermal barrier.

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 the solar cell film is much stronger than the resin of the carbon fiber material."

"This time, the thermal barrier coating has been reduced by 0.28 millimeters."

Chen Yi looked at the new drone that 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 Endurance—Photodynamic Ghost Drone! 】

[Attributes: Energy x49.1, Speed ​​x10.3, Quality x29, Stability x43, Strength x21, Communication x31.7, Radar Shooting x36.6, Avionics x34.5, Beauty x11.8, Endurance Supplement x69.6]

[Note: This is an unmanned aerial vehicle beyond endurance and beyond imagination. Its energy does not come from the surface of the earth, but from the burning sun 150 million kilometers away.

With an average daily life of more than 70 kWh for ten hours, as long as the speed and consumption are slightly controlled, it can become a nearly permanent sky fortress.

Of course, the light conversion rate, which is close to the physical limit of the material, combined with the light-gathering structure distorts the incident and reflection angles of light indefinitely.

This allows it to have the function of optical invisibility, which can hide most of its own figure. Whether it is radar detection or human eye observation, it is as blurry as a ghost]

"It's really perverted."

Chen Yi looked at the remarks and evaluation of the drone, and took off the immersive AR glasses that are sunglasses today.

Originally clear drone.

It suddenly became blurred and flickered.

The overall feeling is like a mosaic, flickering and shaking, completely losing all the original details.

One can imagine

Such a drone, even if it is scanned by radar detection.

This will also be naturally filtered as environmental clutter, and no trace of signal will be found at all.

After all, the radar detection system is not an old driver of artificial intelligence, and it is far from the super high level of mastering the codeless in mind.

"In the future, I will have more drones. I must build a museum to store every drone I have designed over the years."

"From low-altitude to high-altitude to space, from sonic to supersonic to sub-light speed, from planets to interstellar to the universe. Don't miss any of them, 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, plus some improved quality attributes.

Sprayed thermal barrier coating, plus a fully loaded battery and full xenon propellant.

The total weight of the drone is only 42.8 kg, which is less than 3 kg heavier than the previous ion-propelled drone.

If it is thrown away and raised a bit, it will reach a battery weight of 18 kg.

This time the fuselage is a little lighter than the fuselage of the previous drone.

The performance of the engine, because 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 attribute is increased to 49.1, approaching the limit of carbon-silicon lithium battery.

The energy density has exceeded 5900Wh/KG, reaching 5980Wh/KG.

The 18kg battery has a total capacity of 107kw h.

Coupled with a stronger aerodynamic layout, the flight efficiency has increased by 4 percentage points, and the flat design of the stingray is more suitable for high-altitude gliding.

Chen Yi made a rough estimate.

The efficiency of the aerodynamic layout is improved, the efficiency of the engine is improved, and the battery capacity is increased.

According to the comprehensive calculation of 30% low speed, 30% subsonic speed, and 40% supersonic speed.

This drone has a range of over 4,000 kilometers easily.

Combined with unpowered gliding flight, the overall battery life has doubled by seven or eight times, and it is no problem to exceed 20,000 kilometers.

Even if you fly at supersonic speed all the way, and occasionally play some supersonic flying, the battery life is about 900 to 1300 kilometers.

If the gliding flight is combined with the charging and replenishment of the solar cell film, the battery life will further skyrocket, and circling the planet is not a dream at all.

Even if it lands in the end.

It's not that you can't continue to fly, but that your energy can't stand it.

What!

Will the sun go down?

According to the blue star's 466 meters per second rotation speed, fully charged, the supersonic flying machine can catch up with the speed of the setting sun in a few minutes, then glide to charge, then fly to catch up with the sun, and then glide

After confirming the performance of the latest drone that never sets the sun, Chen Yi took out another multi-axis aircraft that he used for test flights when he was operating drones before.

Multicopter.

That is, a drone with multiple axes joined together, each with a propeller.

The well-known DJI company in the industry, all models are such multi-rotor aircraft.

Chen Yi disassembled the casing of the multicopter, 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 air signal relay drone is freshly released.

Compared with the previous moon landing drones, the fixed-wing model aircraft was used as a signal relay.

In this way, it can hover in the air, and the longer-lasting multi-axis aircraft is undoubtedly more suitable as a signal relay.

"Set off!"

Looking at the east, the fish belly has begun to turn white.

Chen Yi felt that he was in a good state of staying up all night cultivating immortals this time, and he didn't bother to rest when he was in a good mood.

He took out his mobile phone and dialed the reporting number of the Air Traffic Management Bureau.

"Hello, this is air traffic control 0A987, what can I do?"

The phone was connected in less than three seconds, and a standard Mandarin female voice came from inside.

"Hello, drone application for test flight, number 0A01, number 0A02."

Hearing the familiar voice on the phone, Chen Yi thought for a while and couldn't remember who it was, then ignored it and told his situation.

"Number 0A01"

over the phone.

Lin Xiaobei was taken aback when he heard the number, and then he 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 Agency."

"."

Now, it was Chen Yi's turn to be restless.

Is it such a big fight?

The opening is the Air Force Management Center and the Space Agency.

"Uh, don't bother, I've learned to keep a low profile, and I 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 when reporting the last moon landing test flight.

"Okay, may I ask the area and route destination of your test flight?"

Lin Xiaobei hesitated for a moment, and began to record the area and route that Chen Yi wanted to apply for a test flight.

"Penghai takes off, latitude and longitude E114, 05, 51.17, N22, 38, 18.79.

First lift off vertically, cross the clouds, enter the high-altitude stratosphere, and then glide westward.

Pass through Guangxi Province, Yunnan Province, enter Hengduan Mountains, Himalayas. Destination, Mount Everest. "

Chen Yi thought for a while, and said his plan for this test flight.

If you want to verify the performance of the drone that the sun never sets, you can only fly in front of the sun from east to west.

over the phone.

Lin Xiaobei was dumbfounded.

She knew that she shouldn't believe that Chen Yi had learned low-key nonsense.

This can be a live broadcast of sprinting into space, live broadcast of landing on the moon, and the guy who was told to focus on it, how could it be possible to keep a low profile.

Silence for a while.

Lin Xiaobei's tone was a little unlovable, and she 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."
