Chapter 33 The ion propulsion drone is finalized, it’s too powerful!

"Read information!"

To make some complaints, Chen Yi chose the control technology of particle thrusters.

A lot of technical information and formulas 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 principles such as magnetic field accident, decoherence, and interference."

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

“However, in order to fully utilize the performance of the algorithm, a special chip is needed.”

It took more than two hours.

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

“Previous brainwave virtual consciousness machines required special chips to fully realize their designed performance, and now ion control also requires special chips.

You can imagine.

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

It seems that if we have time, it is necessary to set up a chip production line and make our own chips."

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

The attribute adjusted and upgraded this time is efficiency.

Read the technical information, Chen Yi discovered.

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

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

But compared with the daily use of low-resistance copper materials, it is more than four orders of magnitude lower, reaching 1.34×10^(-12)Ωm

With this special coil configuration, the coupling between the electromagnetic field generated by electricity and the ions is better, and the confinement and acceleration performance of the ions is even better.

Simply understood, it means consuming less energy and achieving greater acceleration.

One is to reduce resistive losses.

The other side is to improve the acceleration effect.

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

"Strength and quality cannot be adjusted and upgraded individually. We can only wait for the carbon fiber printer to be purchased 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.

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

Re-adjusted and manufactured a batch of avionics main control, communications, radar photography and other accessories.

At 2:30 noon, Qin Xiaoyu and his delivery staff delivered the purchased five ternary lithium electric vehicles, two high-precision carbon fiber 3D printers, and two 3D metal combined printers.

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

With the automatic following workbench and automatic height gauge, the diameter of the printable workpiece can reach up to 2 meters.

Among them, the combined printer has two different sets of printing nozzles.

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

This kind of printer is specially designed for products that combine multiple materials.

Chen Yi just used it to print and make ion thrusters.

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

“The technology of velocity attribute reading brings about the structure of the ion thruster, electric field layout, orbital layout, 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 by the efficiency attribute brings a new type of wire material. This material cannot be produced and replaced for the time being, but the special coil configuration has no problem.

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

Chen Yi sorted out the technologies acquired through today's adjustments and upgrades, and after clarifying his thoughts, put on the virtual helmet.

Beep!

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

A large number of lines and structural artifacts were drawn at an astonishing speed under the virtual control of Chen Yi's brain waves.

Less than an hour.

Two ion thrusters, one on the left and one on the right, including the drone's fuselage, were drawn and designed by Chen Yi.

In the design of the engine, the ducted intake duct has been adjusted and replaced with an intake ram duct, making the high-speed performance even better.

The design of the fuselage is based on the fuselage of the lunar 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 was connected to the printer, and the printer's nozzle began to spray hot powder.

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

It took more than 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.

"The carbon fiber manufacturing is different, and the feeling in hand is completely different."

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

--light.

The density of carbon fiber is generally 1.7.

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

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

This density gap means that a drone of the same design weighs 100 kilograms using titanium alloy, but it weighs up to 40 kilograms if replaced by carbon fiber.

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

Chen Yi sighed, picked up the printed components, as well as communications, radar, hydraulic wheel sets and other accessories that cost more than 400,000 yuan to upgrade, and started assembling them.

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

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 Scout 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 photography x36.6, Avionics x34.5, Beauty x9.8]

[Note: This is the only ion propulsion aircraft in the world with mature design. Despite its low speed, it is equipped with a high-capacity energy module and adopts low-speed aerospace method, so it can still travel in space! 】

"The speed is 10.2, and the speed in space is also 2.8. This is a surprise. I originally thought that it would be more than 9 points in the atmosphere and 1 point in space."

Chen Yi looked at the speed attributes of the drone and felt a little surprised.

As a drone designer, he naturally understands.

The speed of 10.2 is the speed at which the ram air intake duct is opened at low altitude to coordinate with ion propulsion.

As for the speed of 2.8, this is the speed in space where there is no external air intake and is driven entirely by ions.

"Test the weight and thrust performance of the entire 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 later equipped with high-energy batteries, ion propellants, and high-temperature resistant coatings, the weight of the entire machine will not exceed 40 kilograms.

"It's a bit fierce."

Chen Yi showed some surprise, carried the drone to the test bench on the other side, connected the external power supply and started testing.

After more than half an hour of repeated testing.

Finally, Chen Yi determined the thrust values ​​of the ion thruster in different states.

At low altitude and low speed, the injection mass is maximized, and the concurrent thrust of the two engines reaches 863.6 kilograms. Based on the full load weight of 40 kilograms, the thrust-to-weight ratio reaches an astonishing one to twenty-one.

The jet speed is at the subsonic stage, and the concurrent thrust of the two engines is 545.3 kilograms, with a thrust-to-weight ratio of 1:13.

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 rises instead of falling, reaching 592.7 kg, with a thrust-to-weight ratio of one to fifteen.

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

When reaching Mach 5, the concurrent thrust of the two engines is only 289.0 kilograms, and the thrust-to-weight ratio is one to eight.

But no matter which state it is in, as long as it is below an altitude of 20,000 meters and within the speed range of Mach 5.

The performance of this ion propulsion drone is no weaker than the previous space sprint drone.

If it enters space, its endurance and continuous acceleration capabilities will surpass those of space sprint drones and moon landing drones.

"too strong!"

“This half month of study and hard work has paid off!”

Chen Yi shouted excitedly: "Get an ultra-high-energy battery tonight, and apply a thermal barrier protective coating to the drone. We can officially test fly tomorrow!"
