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

It was more than two o'clock in the morning.

Qin Xiaoyu got up to go to the bathroom, and saw the bright lights on the second floor next door.

He was stunned for a moment, and then he understood that Yifei should have nothing else to do recently.

Because Chen Yi was messing around all night again.

Not only did Xia Keke know, she also knew Chen Yi's character well.

Except when I first started my business, my usual working hours would never exceed seven o’clock, and the things I couldn’t finish were the next day’s work.

To make Chen Yi give up health preservation and stay up all night cultivating immortality, there is nothing else to do except to play games.

"Prepare an extra breakfast tomorrow that reheating will not affect the taste"

After setting a breakfast reminder, Qin Xiaoyu went back to sleep after going to the bathroom, and didn't say anything like asking, reminding, asking Chen Yi to go to bed early.

"Finally done."

"This engine is several grades more complicated than the previous engine."

"If you don't know all the technologies and structures well, you may not be able to get it done in half a month."

It took almost eight hours.

From design to manufacture, Chen Yi finally rolled out the latest engine for landing on the moon.

This is an engine with tens of thousands of accessories, 3.63 meters in length and 63.3 centimeters in maximum diameter. It is the largest engine ever made by Chen Yi. .

Just by looking at it, it is clear that there is a lot of technology.

[Item: Polar Magnetic Variable Specific Impulse Plasma Engine]

[Attributes: thrust x15.9, specific impulse x100, control x99.8, efficiency x10.9, strength x28.9, beauty x12.6]

[Note: This is an engine with a magnetic confinement electric field, which can accelerate the injection of propellant with extreme thermal acceleration, and has an extreme specific impulse.

As long as there is enough energy propellant, it will satisfy your rudimentary dream of interstellar exploration.

If you can provide enough power energy, maybe it will bring you some other surprises. 】

"The magnetic confinement electric field can be changed to match with the ultra-high temperature generator. It can be used to attack the drone and build an aircraft carrier killer, but the size of the current attack drone can't fit."

Chen Yi simply imagined it, and soon thought of the application of the technology here in other fields.

"I feel like if this continues, I can have a deep grasp of the entire field related to aircraft. It is not an exaggeration to call it a science and technology museum."

Chen Yi complained to himself, and began to design a straight-line back and forth moon landing drone based on the engine of this powerful bunker.

"The first point is energy. No matter how powerful the engine is, if you want to drive an aircraft, you need energy."

"The ion thruster prompts to increase the injection speed and improve the specific impulse performance. This can only save propellant, but it does not save energy consumption at all."

"On the contrary, on the premise of the same thrust, the faster the injection speed of the propellant, the higher the power required and the greater the energy consumption."

"Well, let's start with a basic exercise."

"A battery membrane with a conversion rate of 84.6 percent."

"Add a set of the strongest carbon-silicon lithium battery with 5980Wh/KG."

"At the same time, refer to the UAV that the sun never sets, and increase the surface area of ​​the fuselage as much as possible."

"There is another set of hidden solar panels. In space, there is no air resistance. Such panels are energy supplements."

"The battery board with a conversion rate of 84.6% is also used, combined with a retractable inflatable frame, it can be popped up when it is used, and it can be put away when it is not in use.

Um, inflatable stretch doesn't seem to work.

The girlfriend needs to stack it manually if it is deflated. The same is true for this deflation, and it cannot be collected.

Or change it to a carbon fiber X-shaped telescopic frame, stretch it out if you want to use it, and retract it if you don’t need it. "

"In addition, attitude control in space, safety protection, heat-resistant design for re-entry, and fuselage design also need to be considered."

"The last is a relay satellite similar to "Magpie Bridge", which is arranged at the L2 Lagrangian point.

I am already familiar with satellite technology.

This is to build a self-launch satellite to strengthen the communication remote sensing function.

Once in space, dock and hook the lunar landing drone, and drag it to the L2 Lagrangian point.”

Countless knowledge of aerospace and ion thrusters flashed through Chen Yi's mind.

Based on these knowledge information, combined with the situation of the space environment.

Chen Yi quickly determined the general configuration of the new moon landing drone.

This is a drone with a length of 5.07 meters, a wing of 4.76 meters at its widest point, and a drone of 1.98 meters including the landing gear.

The overall shape adopts the advanced waverider configuration.

It presents a triangular rhombus, but it is much more rounded than the rhombus, and there are many micro jets at different angles on the surface.

For lunar drones, the aerodynamic layout in the atmosphere is no longer the main thing.

Powerful flying bricks, a powerful engine is more than enough to make up for some aerodynamic deficiencies.

"Next, there is the material of the fuselage.

Still imitating the drone that never sets, the innermost part uses carbon fiber as the base frame, followed by a layer of solar cell film.

A special optical coating is added on the battery film to reflect the 15% of the light that is not absorbed in a regular manner, eliminating blur and mosaic.

The outermost layer is a layer of transparent beryllium oxide ceramics, which serves as a thermal barrier protection and physical protection, forming a four-layer composite structure.

This time, the carbon fiber adopts a new weaving technology, the tensile strength is increased by 135%, and the yield strength is increased by 2.3 times, which is enough to cope with the use environment of the moon landing drone.

In addition, considering the intense friction of re-entry into the atmosphere, the thickness of the beryllium oxide ceramics on the nose and belly of the fuselage needs to be increased by 2.3 times.”

Chen Yi roughly calculated the heat of re-entry into the atmosphere, adding 2.3 times to the beryllium oxide ceramics on the fuselage belly and nose.

It was originally planned to add a layer of heat-insulating ceramic tiles according to the design of the space shuttle.

However, considering the shedding and one-time problems of ceramic tiles, this solution was abandoned.

"Start manufacturing!"

The overall configuration and material scheme of the fuselage are determined.

Chen Yi put on the virtual helmet and began to design and manufacture the specific structural components of the drone, as well as the supporting functional modules.

It was past four in the morning.

All designs are completed.

Import automated manufacturing procedures to arrange production.

It was past six in the morning.

New base with new production equipment.

All accessories and components needed by Chen Yi have been produced.

Three-layer composite structure fuselage components, communication modules, signal components, UAV main control core, propellant fuel tank, radar, hydraulic wheel set, carbon-silicon lithium battery, X-shaped retractable solar panel, to improve safety protection Laser weapons and more.

All the accessories and components of the drone were placed in front of Chen Yi together.

After some assembly.

Soon, the whole body was black, without the distorted fuzzy feeling like a drone that never sets.

The overall shape is roughly triangular, with a waverider structure, but a thicker and rounder drone appeared in front of Chen Yi.

[Item: Extreme Specific Impulse - Recently-style Space Stealth Unmanned Fighter]

[Attributes: Energy x49.1, Propellant x98.2, Speed ​​x15.9, Mass x34, Stability x42, Strength x26.7, Communication x31.7, Radar Shooting x36.6, Avionics x34.5, Beauty x13. 8. Energy Supplement x78.6]

[Note: This is an engine with extreme specific impulse, which is beyond imagination, and can travel to the moon, Venus, and Mars in a straight line.

The special energy replenishment design allows it to achieve almost inexhaustible energy in the near area.

The powerful specific impulse brings efficient propulsion, allowing it to fill ten propellants for three days and three nights without rest.

If you master the technology of gravitational acceleration around stars.

It can also go on a walk-and-go journey across the starry sky.

When your great-grandson’s son burns paper for you, it can convey your thoughts to Proxima Centauri. 】

"Is it so violent to raise ten times for three days and three nights without rest?" Chen Yi was surprised by the drone's evaluation.

"Visiting Proxima Centauri in my lifetime will be even more intense."

"If I remember correctly, the nearest Proxima Centauri is 4.2 light-years away from the sun. Based on the 30-year-old generation who married late, my grandson is 60 years younger than me, and my great-grandson is 90 years younger than me.

The son of the great-grandson needs to burn paper, which means that the great-grandson has died. Based on the average life expectancy of more than 80 years, it will be about 180 years later.

Meaning this stuff.

Can you reach Proxima Centauri in 180 years, at a speed of 2.3 percent of the speed of light? "

Chen Yi was shocked.

2.3 percent sounds low.

Even bank regular interest can't compare.

Not to mention the annualized rate of 20 or 30 percent for telecom fraudsters.

But if this percent is 2.3, multiply it by a speed value.

Not high, just 300,000 kilometers per second.

In an instant, the meaning is different.

2.3 percent immediately becomes 7000 kilometers per second.

This is much stronger than the strongest nuclear-powered manhole cover.

Not to mention flying out of the Orion cantilever, there is no problem flying out of the Milky Way.

"It is worthy of giving 1,000 Three Gorges Power Stations energy and power, and they can use sub-light speed jet propulsion engines."

"The drones made with this engine are also different."

Chen Yi sighed, looked at the drone in front of him, opened the hatch, and checked.

"There is quite a lot of internal space, and it is no problem to sit a few children."

"You can add a lunar sweeping robot to the drone, the mechanical one, otherwise the moon will not be able to absorb air without air."

"The energy of the sweeping robot is charged by the laser of the drone. This thing exists in reality, just change it to increase efficiency."

"It's rare to go to the moon. If you don't help sweep the floor, how can you bring some souvenirs back?"

Sweeping robot.

This stuff is easy.

It didn't even take an hour, Chen Yi based on the existing style and structure of the sweeping robot.

It has been changed to an off-road robot that is several times larger in size, has a large storage bin on its back, has replaced wheels with crawlers, and has a chassis that can be propped up high.

[Item: Tracked digging and cleaning robot]

[Attributes: energy x49.1, excavation and cleaning x14.7, storage x19.8, supplementary energy x43.1]

[Note: This is a cleaning robot used in a special environment. It can be used at home to change the floor style to obtain a neat and uneven floor.

Maybe you could use it to build roads and do digging and sweeping before asphalting. 】

"Is the evaluation so low?"

"I'm a sweeping robot, not a road digging robot."

Make sure there is no problem with the function.

Chen Yi didn't care about the evaluation.

Put the sweeping robot through the openable hatch of the drone, stuff it into the drone and fix it, and wait for it to be sent to the moon together to start its brilliant sweeping life.

"The speed on the other side is still too slow."

"I have built the moon landing drone, but they haven't even issued the moon landing announcement."

Send the request for the relay satellite to Xuannv, indicating production.

Chen Yi looked at the moon landing plan that was not moving at all.

After thinking about it, he dialed the phone and asked a few words.

"To avoid targeting Yifei, prepare to launch within two hours after the announcement, and not release the announcement in advance?"

"Good guy, if you want to avoid being targeted, at least you should make up for your secrecy and protection like a sieve."

Chen Yi hung up the phone with a strange expression on his face.

After thinking about it, I took a photo of a new moon landing drone, and then found out the close-up photos of the moon taken by the last moon landing drone.

According to the time of the opposite moon landing, a live broadcast notice was released.

【exist? Smoke 10 copies of lunar soil! At ten o'clock in the morning two days later, the moon landing operation will begin immediately! 】

Chapter one, two more chapters tonight
