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

"Sure enough, except for the relatively strong properties of the material and the newly replaced communication module, other properties are relatively poor, especially the speed property."

Looking at the attributes of this turbojet model airplane, Chen Yi felt emotional.

This model airplane is a turbojet model airplane he assembled two months ago when he was preparing for transformation. The casing is stamped from a piece of the best aerospace titanium alloy obtained through his relationship.

However, because the turbojet engine was too backward, Chen Yi did not have the channels and technology to improve the engine. The speed of the assembled turbojet model aircraft was not even comparable to that of a general ducted model aircraft, and finally announced the failure of the transformation.

After all, when playing model airplanes, switching from a duct to a turbojet, in addition to the whistling sound of the turbojet, the most important thing is that the speed of the turbojet model is faster and can complete more flight actions.

A turbojet model aircraft of a fast aging classic aircraft.

Don't expect anyone to buy unless your customers are crazy.

"Xiao Yu, look at the store, I'll go up and modify the model airplane."

Chen Yi ordered, took some accessories, and went up to the second floor with a model airplane weighing more than 70 kilograms.

"The most important attribute of a turbojet model is speed. When shooting live video, the most shocking and intuitive performance is also speed.

2689 wave of consciousness, keep 400 for spare, and you can also adjust 11 points of attributes.

Don't think about it, mainly adjust the lifting speed.

If you can fly a sonic boom cloud, you can make a lot of money selling engine modules! "

Chen Yi looked at the attributes of the model airplane, thought for a while, and decided to take 4 points from the 11 points of attributes to the aesthetics.

His main selling point this time is speed. It doesn't matter if he is beautiful or not. Violence is the theme of men.

Then subtract 5 points from the material, ie strength.

Now the aircraft models use aerospace titanium alloy materials.

For this kind of material, he got a little leftover material through his relationship, and stamped the shell of such a model airplane.

It is too extravagant to use the top aerospace materials to build an aircraft, and the attributes are obviously many.

In this way, 5 points of attributes are subtracted, and the attributes of 9.4 are retained, which is enough for the model aircraft to fly a few waves.

Chen Yi intends to squeeze out the last two attributes in the communication module.

The communication modules installed this time cost several thousand each. It is said that the antennas are installed on the ground, and the model airplanes can communicate smoothly when they fly into space.

With an attribute of 12.5, 10.5 is enough after subtracting two points.

As for other energy sources, stability, radar, and avionics.

Energy is related to how far and high the model airplane can fly, stability represents whether the model airplane can fly, avionics represents the control of the model airplane, and radar photography represents the shooting effect from the first perspective.

If this model flight is going to be a hit, nothing can be reduced.

After confirming the adjustment plan, Chen Yi started to act.

Swish!

Colorful rays of light bloom on the surface of the aircraft model.

The original smooth and beautiful shell of the model airplane suddenly turned dull and gray, and finally turned into a layer of gray steel.

The surface of the steel is also covered with strangely shaped solder joints, pitted and twisted traces.

It seems that this is not a product of industrialization, but a 70-year-old blacksmith who has become dizzy at the head of the village, smashing it out with a hammer.

Chen Yi looked at the aircraft model in front of him, which had become much larger, with a wingspan of more than one meter, and a more slender proportion, but its appearance had become ugly.

"These solder joints are pitted and ugly, but they seem to conform to some aerodynamic layout configurations"

Chen Yi lifted the tail of the airplane model, and two engine nozzles with completely different styles were revealed.

The dark golden surface, circles of quenching patterns, and more than 3 layers of mechanical meshing structure, all tell people.

These are two high-tech engines that can adjust the diameter of the nozzle independently, without any hard work.

[Item: Fixed-wing aircraft model drone]

[Attributes: Energy x7.3, Speed ​​x13.8, Stability x4.9, Strength x9.4, Communication x10.5, Radar Shooting x6.1, Avionics x8.7, Beauty x2.1]

[Wave of Consciousness: 489]

[Adjustable attribute: 0]

[Detecting that a certain attribute exceeds the initial value, do you want to read the information? whether! 】

[Note: This is a shockingly ugly model airplane drone with a bold design, combining turbojet and stamping features.

If you can add oxidizer, maybe it can bring you some other surprises! 】

"Damn it, add oxidizer. Could this thing really go into space?"

Seeing the note on filling the oxidizer, Chen Yi couldn't help but open the fuel filling compartment of the model airplane.

Sure enough, in addition to a kerosene filling port in the filling compartment, there is also a filling port similar to the hydrogenation of hydrogen energy vehicles.

Obviously, this filling port is only used to fill the oxidant.

"You really want to go to heaven, but can this material and structure work?"

Chen Yi looked at the model airplane with only 9.4 strength attribute and 4.9 stability attribute left.

Although he is not a professional, he also understands that the strength and structure of the material are critical as long as it is a thing for spaceflight.

Whether it was the explosion of Big Brother's rocket or the failure of Fat Five's several launches, it all has something to do with the strength of the material and the design structure.

"It doesn't matter, find an acetylene-burning construction site to add some oxygen to it later, and then fly towards the ocean. If you fail, you won't be able to hit anyone. It's like setting off fireworks."

"It is equipped with a first-view camera, as long as it can reflect the awesomeness of the engine!"

Chen Yi thought about it for a while, and then stopped thinking about it at all, and read the information related to the speed of the model aircraft.

boom! Countless messages were read by Chen Yi.

This information includes the design and design principles of the aircraft model engine, the ratio of materials and process structure, and some data on the aerodynamic layout of the aircraft.

Ten minutes later, Chen Yi opened his eyes and looked at the bumpy model airplane in front of him.

"I didn't expect that these bumpy and ugly traces are really related to some aerodynamic layouts.

It seems that the various attributes of the item are a whole. If a certain attribute is adjusted too extreme, it will affect the situation of other modules.

For example, now that the speed attribute is adjusted, in addition to the engine becoming more powerful, the proportion of the aircraft model and the aerodynamic layout have also changed. "

Chen Yi digested the information in his mind, except for the design of the engine and the aerodynamic layout of the model airplane.

There is also a new technology and process for low-temperature thermal strengthening of stress materials.

One is smelted at low temperature, and its initial strength is very ordinary.

However, as the ambient temperature increases, the thermal stress inside the material increases, and the strength of the material increases exponentially.

According to the information read, the engine of this aircraft model is now using low-temperature heat-strengthening materials.

At the beginning, the strength of the engine material was relatively low, and the strength was not even comparable to that of rebar.

When the engine starts, the internal combustion begins to do work, the temperature of the engine continues to rise, and the strength of the material will continue to increase.

Finally, it reaches the strength of titanium powder alloy, and its heat resistance exceeds that of ordinary nickel-based alloys.

The advantage of this is that the complex cooling system of the engine is omitted, which is very suitable for small UAVs such as model aircraft.

However, this material is not without its drawbacks.

That is, the durability is not as good as that of real titanium powder alloy, and at the same time, it cannot withstand damage and disassembly after setting.

Because of the thermal stress, once it is destroyed and disassembled, the internal stress explodes.

The whole material collapsed in an instant like Rupert's tear whose tail was pinched off.

In addition, when the strength increases to a critical value for a certain period of time, or the temperature lasts for a certain period of time, the stress inside the material will not be restrained, and it will still collapse irreversibly.

"The characteristics of this material are absolutely confidential, but it does not conform to the current mainstream of recyclable rockets."

"However, the manufacturing cost is quite low, only one tenth of that of titanium alloy materials. In addition, the initial strength is low. If the precision of the factory's processing equipment is systematically adjusted, Yifei's small factory workshop can also manufacture it."

Chen Yi wrote down the types of metals needed to make the engine materials, mixed with some other types and sent them to Qin Xiaoyu, signaling him to find a supplier to place an order and send it over urgently.

After arranging the work, Chen Yi took the new model airplane out of the shop, ready to fill the model airplane with aviation kerosene and liquid oxygen, and test the flight to see what surprises are there.
