"Read the message!"

After complaining, Chen Yi chose the control technology of the particle thruster.

A lot of technical information and formula principles come to mind.

"This is a kind of chip design diagram, as well as the control algorithm of electric field and magnetic field, and the algorithm involves the principles of magnetic field occasional, decoherence, interference, etc."

"This algorithm, I feel that the tokamak device can also be used, can greatly reduce the magnetic field loss of the nuclear fusion device, and reduce the energy consumption of the device itself."

"However, in order to fully exploit the performance of the algorithm, a special chip ...... is needed"

It took more than two hours.

Chen Yi roughly understood the information and knowledge he digested, and there was a trace of emotion in his eyes.

"In the past, brainwave virtual consciousness machines needed special chips to fully exert the performance of their designs, and now ion control also needs special chips.

As you can imagine.

As the high-tech content of items continues to improve, more and more devices will need special chips.

It seems that there is time, it is necessary to get a chip production line and make chips yourself. ”

Chen Yi first wrote down this matter in his planner and continued to adjust and upgrade the ion thruster.

This time the attribute of the adjustment upgrade is efficiency.

Reading the technical information, Chen Yi found.

This is a low-resistance conductor material technology, a special coil configuration.

Although it is not as good as the zero resistance of superconducting materials.

However, it is more than four orders of magnitude lower than the low-resistance copper material for daily use, reaching 1.34× 10^(-12)Ωm

In this special coil configuration, the coupling between the electromagnetic field and ions generated by energizing is better, and the confinement and acceleration performance of ions are more superior.

To put it simply, it is to consume less energy and get more acceleration.

On the one hand, it is necessary to reduce resistance losses.

On the other hand, the acceleration effect is increased.

Combined, the efficiency is 80 percent higher than that of the current HET-186 Hall thrusters on the Tianhe space station.

"The strength and quality can't be adjusted and upgraded alone, so we can only wait for the carbon fiber printer to buy it and try again."

The three core attributes of speed, control, and efficiency have been adjusted successively, and the time has passed for half a day to read the technical information.

Chen Yi went out for lunch.

I came back to use the previous drone accessories, as well as the radar components purchased through Professor Zhang.

A number of avionics main control, communications, radar shooting and other accessories have been readjusted and manufactured.

At half past two o'clock in the afternoon, Qin Xiaoyu took the delivery staff to send the five ternary lithium electric vehicles he had purchased, as well as two high-precision carbon fiber 3D printers, and two 3D metal combined printers.

Carbon fiber printer is a relatively large machine on the market.

In combination with the self-following table and the automatic altimeter, workpieces can be printed up to 2 meters in diameter.

One of the combined printers has two different sets of printhead.

One group is responsible for printing metal components, and the other group can jointly print plastic and carbon fiber.

Such printers are designed specifically for products where multiple materials fit together.

Chen Yi happened to use it to print and make ion thrusters.

This is because the coil that generates the electric field inside the ion thruster is exactly inside the propellant.

"The technology of reading the velocity properties brings the structure of the ion thruster, the layout of the electric field, the layout of the track, etc.

The technology of controlling attribute reading brings control algorithms, and although there is no special chip, it can also be applied to general-purpose chips.

The information read by the efficiency property leads to a new type of wire material that cannot be produced and replaced for the time being, but there is no problem with the special coil configuration.

Combined, these technologies are sufficient to produce a prototype of an ion thruster. ”

Chen Yi sorted out the technology obtained by adjusting and upgrading today, and after clarifying his thinking, he put on a virtual helmet.

Backbite!

Next to the computer turn on and open the CAD software.

A large number of lines and structural artifacts began to be drawn at an astonishing speed under the virtual control of Chen Yi's brainwaves.

Less than an hour.

The two ion thrusters, one on the left and one on the right, including the fuselage of the drone, were drawn and designed by Chen Yi.

The design of the engine, the ducted air intake duct has been adjusted and replaced with an air intake ram duct to provide superior high-speed performance.

The design of the fuselage is to refer to the fuselage of the lunar landing drone with up to 40 attributes, and to make certain enlargements and adjustments to ensure the structural stability of the fuselage and the performance of the aerodynamic layout.

Da-da-da-da!

The computer is connected to the printer, and the printer's nozzle begins to spray hot powder.

These powders are stacked together according to a certain trajectory and height ratio, and fuse with each other under high temperatures, gradually forming components of ion thrusters and drone fuselages.

It took more than four hours and four large 3D printers working at full power.

Finally, at seven o'clock in the evening, all the drone components of Chen Yiyao were produced.

"Carbon fiber is just different, and the feeling of getting it in your hand is completely different."

Chen Yi picked up a cooled component, swiped it twice in his hand, and felt that it was just one word.

- Light.

The density of carbon fiber is generally 1.7.

This doesn't sound like much feeling, but you must know that Chen Yi used the lightest aluminum alloy before, and it was generally 2.8.

If titanium alloy is used, the density generally reaches more than 4.5, and the density of other nickel alloys is more than 7.5.

Such a density gap represents a drone of the same design, which weighs 100 kg using titanium alloy and is replaced with carbon fiber, and weighs up to 40 kg.

"It's no wonder that the supercars are made of carbon fiber, and the weight savings will undoubtedly improve the performance and lap times of the supercars."

Chen Yi sighed with emotion, picked up the printed components, as well as the communications, radars, hydraulic wheels and other accessories prepared in advance, and began to assemble.

Soon, a drone that uses ion propulsion and is unique in the world appears in front of you.

The wings and fuselage of the drone are almost fused together, and the shape is like a sharp triangle, similar to the latest version of the Detective 8 or the opposite S72-Black Hawk.

[Item: Ion Propulsion Drone]

[Attributes: Energy x0, Speed x10.2~2.6, Mass x21, Stability x35, Strength x14, Communication x31.7, Radar Shooting x36.6, Avionics x34.5, Beauty x9.8......]

[Note: This is a mature design, the world's only ion propulsion vehicle, don't look at its low speed, with a high-capacity energy module, using a low-speed aerospace method, still in space! ] 】

"The speed is 10.2~2.6, and the fluctuation is a bit big.

However, it was a surprise that the low-altitude speed could reach 10.2, and at first I thought it was only more than 9 points. ”

Chen Yi looked at the speed attribute of the drone, and showed a little surprise in his heart.

As the designer of the UAV, he naturally knew it.

10.2 speed, which is the speed at which the ram intake duct is opened at low altitude with ion propulsion.

And the speed of 2.8, this is the speed of going to space, there is no external air intake, and it is all propelled by ions.

"Test the weight and thrust performance of the whole machine."

Chen Yi picked up the drone and walked to the weighbridge next to him, and after three repeated measurements, the weight of the drone was determined.

13.9 kg.

After a series of technical integration, structural optimization, reduction of unnecessary components, and replacement of carbon fiber materials, the weight of the entire drone has been reduced to an astonishing value.

Even if it is equipped with high-energy batteries, ion propellants, and high-temperature resistant coatings, the weight of the whole machine will not exceed 40 kg.

"It's a little fierce."

Chen Yi showed a little surprise, hugged the drone to the test bench on the other side, connected the external power supply and started the test.

After more than half an hour of repeated testing.

In the end, Chen Yi determined the thrust value of the ion thruster in different states.

At low altitude and low speed, the jet mass is maximized, and the thrust of the two engines reaches 863.6 kg concurrently, and the thrust-to-weight ratio reaches an astonishing 1:21 based on a full load weight of 40 kg.

The jet speed is in the subsonic stage, and the thrust of the two engines is 545.3 kg, and the thrust-to-weight ratio is 1 to 13.

The jet speed is in the supersonic stage, at this time, because the speed enters the maximum performance range of the ram duct, the thrust of the two engines does not decrease but rises, reaching 592.7 kg, and the thrust-to-weight ratio is one to fifteen.

This thrust increase will continue from supersonic speed to Mach 3.5 jet speed, and then the attenuation of top speed.

When it reaches Mach 5, the thrust of the two engines is only 289.kg, and the thrust-to-weight ratio is one to eight.

But no matter what kind of state, as long as it is below 20,000 meters in the air and within the range of Mach 5 speed.

The performance of this ion-propelled drone will not be weaker than that of the previous space sprint drone.

If you go into space, the endurance time and continuous acceleration ability are even more like hanging space sprint drones and moon landing drones.

"It's too strong!"

"This half a month of study and hard work has not been in vain!"

Chen Yi shouted with some excitement: "Get an ultra-high-energy battery tonight, and then get a thermal barrier protective coating for the drone, and you can officially test it tomorrow!" ”
