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

Chapter 33 The ion propulsion drone is finalized, it's too strong!
"Read the message!"

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

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

"This is a design diagram of a chip, as well as a control algorithm for electric and magnetic fields. The algorithm involves the principles of magnetic field coupling, decoherence, and interference."

"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 required"

It took over two hours.

Chen Yi roughly understood the information and knowledge he had read, with a hint of emotion in his eyes.

"The previous brain wave virtual consciousness machine needed a dedicated chip to fully exert the performance of the design, and now the ion control also needs a dedicated chip.

Imagine.

As the technological content of items continues to increase, more and more devices will require dedicated chips.

It seems that if there is time, it is necessary to set up a chip production line and make chips by ourselves. "

Chen Yi first recorded this matter in his schedule, and continued to adjust and upgrade the ion thruster.

The attribute of this adjustment and upgrade is efficiency.

Chen Yi found out after reading the technical information.

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

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

But it is more than four orders of magnitude lower than the low-resistance copper material used in daily use, reaching 1.34× 10^(-12)Ωm
With this special coil configuration, the coupling between the electromagnetic field generated by electrification and ions is better, and the confinement and acceleration performance of ions is more superior.

Simply understood, it consumes less energy and obtains greater acceleration.

One side is to reduce the resistance loss.

The other side is to improve the acceleration effect.

When the two are superimposed, the efficiency is 80% of the current HET-186 Hall thruster of Tianhe Space Station.

"Strength and quality cannot be adjusted and upgraded in a single way. We can only wait for the carbon fiber printer to be bought back and try again."

After adjusting the three core attributes of speed, control, and efficiency, and reading the technical information, half a day has passed.

Chen Yi went out for lunch.

Back to use the previous drone accessories, and the radar components purchased through Professor Zhang.

Readjusted and manufactured a batch of avionics main control, communication, radar shooting and other accessories.

At 02:30 noon, Qin Xiaoyu took the delivery staff and delivered the purchased five ternary lithium electric vehicles, two high-precision carbon fiber 3D printers, and two 3D metal joint printers.

Carbon fiber printers are relatively large machines on the market.

With the automatic following table and automatic height gauge, the maximum diameter of the printable workpiece can reach 2 meters.

The combined printer has two different print nozzles.

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

Such a printer is specially designed for products where multiple materials fit together.

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

Because the coil that generates the electric field inside the ion thruster just fits inside the propellant.

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

The technology of controlling attribute reading brings control algorithms. Although there is no dedicated chip, general-purpose chips can also be applied.

The information read from the efficiency attribute brings a new type of wire material. This material cannot be produced and replaced temporarily, but there is no problem with the special coil configuration.

All combined, these technologies are sufficient to produce a prototype ion thruster. "

Chen Yi sorted out the technology he had obtained through adjustments and upgrades today, and after clarifying his thoughts, he put on the virtual helmet.

beep!

Turn on the computer next to it and open the CAD software.

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

Less than an hour.

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 intake duct has been adjusted and replaced with an intake ram duct to make the high-speed performance better.

The design of the fuselage is based on the fuselage of the moon landing drone with up to 40 attributes, and certain enlargements and adjustments are made to ensure the structural stability of the fuselage and the performance of the aerodynamic layout.

Da da da!
The computer is connected to the printer, and the nozzle of the printer starts to eject hot powder.

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

It took over four hours, with four large 3D printers working at full power.

Finally, at seven o'clock in the evening, all the drone components that Chen Yi wanted were produced.

"Carbon fiber is just different, and it feels completely different when you get it."

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

--light.

The density of carbon fiber is generally 1.7.

This may not sound like much, but you must know that before Chen Yi used the lightest aluminum alloy, it generally required 2.8.

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

Such a difference in density means that a UAV of the same design uses titanium alloy weighing 100 kg, but replaces it with carbon fiber and weighs up to 40 kg.

"No wonder, all supercars use carbon fiber bodies. The saved weight will undoubtedly better improve the performance and lap times of supercars."

With a sigh of emotion, Chen Yi picked up the printed components, as well as accessories such as communication, radar, and hydraulic wheel sets that cost more than 40 to upgrade and upgrade, and began to assemble.

After the assembly is complete, adjust the stability properties to eliminate the problems caused by printing accuracy.

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

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

[Item: Ion Propulsion Drone]

[Attributes: Energy x0, Speed ​​x10.2 (2.8), Quality x21, Stability x35, Strength x14, Communication x31.7, Radar Shooting x36.6, Avionics x34.5, Beauty x9.8]

[Note: This is a well-designed, unique ion-propelled aircraft in the world.

Through the unique electric field acceleration chamber design, combined with powerful control technology, it replaces the combustion and expansion work of the conventional chemical engine combustion chamber, making it a unique electric-propelled drone.

Regardless of its low speed, with a high-capacity energy module, it can maintain long-term acceleration and easily surpass existing aircraft in the atmosphere. 】

"The speed is 10.2, and the speed in space is also 2.8. This is a surprise. I thought it would be more than 9 o'clock in the atmosphere and more than 1 o'clock in space."

Looking at the speed attribute of the drone, Chen Yi was a little surprised.

As the designer of the drone, he naturally knows it.

The speed of 10.2, which is to open the ram intake duct at low altitude to match the speed of ion propulsion.

As for the speed of 2.8, it is in space, without external air intake, and it is all driven by ions.

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

Chen Yi picked up the drone and walked to the scale next to it. 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 bit fierce."

Chen Yi showed a bit of surprise, carried 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.

In the case of low altitude and low speed, the injection quality is maximized, and the concurrent thrust of the two engines reaches 8.46 kN. Based on the full load weight of 40 kg, the thrust-to-weight ratio reaches an astonishing 21:[-].

The jet speed is in the subsonic stage, the concurrent thrust of the two engines is 5.34 kN, and the thrust-to-weight ratio is [-]:[-].

The injection 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 increases, reaching 5.89 kN, and the thrust-to-weight ratio is [-]:[-].

This thrust increase will continue from supersonic speed to jet speed Mach 3.5, and then there will be an extremely fast decay.

After reaching the state of Mach 5, the concurrent thrust of the two engines is only 2.85 kN, and the thrust-to-weight ratio is one to eight.

But no matter what kind of state it is, as long as it is below 2 meters above sea level and within the range of Mach 5 speed.

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

If it enters space, its battery life and continuous acceleration capability will even beat space sprint drones and moon landing drones.

"too strong!"

"The study and hard work of the past half month have not been in vain!"

Chen Yi shouted excitedly: "Get an ultra-high-energy battery tonight, and give the drone a layer of thermal barrier protection coating, and it will be able to officially test flight tomorrow!"
