The plane was born to realize the dream of human beings flying. When the Wright brothers first flew to the blue sky with their dreams, it attracted the attention of countless people. At that time, it was indeed a bigger toy.

Now, what Chen Zheng wore glasses and others made is indeed a huge toy.

Its appearance is very similar to the World War I aircraft: single-engine, double-layer wings, fixed landing gear, and no cockpit.

Especially the two layers of wings, which are connected by countless supporting sticks and wire ropes. The entire plane is not painted. Looking around, there are untreated wood colors everywhere, which looks very unsolid.

This prototype took Chen Zheng and the others a whole day to make it. Since there was no suitable adhesive, many places were linked with rivets, which added a lot of weight out of thin air.

However, the added weight is nothing to the 450-horsepower electric motor of the snowmobile.

Since the main structure of the entire aircraft uses wood, even the motor and zero-electric conversion equipment are counted together, the total weight is less than 1 ton. Even after being equipped with an electromagnetic gun, mass single and air-liquid combined cooling system, the lifting weight is only more than two tons or less than three tons.

As for the entire aircraft, the most difficult part is not the power, structure, flight control, etc., which I thought would have problems. Surprisingly, the problem lies in the landing gear system.

Since there is no manganese, reliable spring steel cannot be created, and the replacement materials are completely clueless, it was actually stuck in this small link, resulting in the suspension of development progress.

After repeated calculations by the man with glasses, the cushioning problem of the landing gear is still unsolvable. In the end, Chen Zheng provided an emergency idea: a thick stack of thin sheets and thin iron sheets are superimposed for buffering, and the huge impact on landing is absorbed through the deformation of the metal.

Yes, the buffer device created according to this idea is disposable.

In this way, with all kinds of "temporary measures" on his body, such a prototype that compromised to the extreme in engineering was finally manufactured.

On this open ice surface, large areas of snow have been cleared out, and even a layer of soft wood chips and soil are covered with.

On the shore, Chen Zheng and the girl stood together, while the man with glasses and others were nervously testing the remote control system.

"Are you serious?" the girl suddenly said.

"Well." Chen Zheng looked at the plane and suddenly turned around and said seriously: "Just as I said before, many great inventions were just toys when they first appeared."

"You have so much confidence in yourself... do you think you can succeed?"

Chen Zheng shook his head, "It must be successful!"

“Buzz buzz…”

As soon as the words were finished, the plane's engine began to rotate, and the propeller blew the grass clips on the ground to fly...

"Sir, will you start-" Amid the huge noise, the man in glasses came to Chen Zheng and shouted loudly.

"Start!" Chen Zheng nodded.

As the man with glasses waved his hand at his younger brother, the wooden plane jumped out! After sliding less than a hundred meters, it suddenly pulled out an arc that was almost straight upward and soared straight upward!

This was almost caught up with the helicopter... Chen Zheng frowned.

The exaggerated thrust-to-weight ratio gives it very excellent maneuverability, but although the body structure of this aircraft has been calculated by men with glasses, the instrument is not a professional supercomputer after all.

There are no professional algorithms such as pneumatics, mechanics, etc. in this computer. The calculation mathematical model is completely studied and input by several people including glasses. It makes people wonder its reliability.

"Tell him to fly well!" Chen Zheng said to the man in glasses.

"Sorry... he might be a little... I'll go right away." Seeing Chen Zheng's expression was not kind, the man in glasses quickly slipped back to his own side and slapped the operator.

After that, the trajectory of the plane became regular. After completing a series of tests in a steady manner, he passed over Chen Zheng and others' heads and ran until he rushed down...

As the plane got lower and lower, Chen Zheng's heart also rose to his throat. When it landed safely, before it could stop, Chen Zheng jumped over and faced the strong wind of the propeller to check the position of the landing gear.

The deformation of the thick stack of copper and iron buffer device is not as huge as imagined, and its deformation is even less than one-tenth of the expected one. This is exactly the Yu Fu that Chen Zheng reserved for the future installation of the weapon system.

"How is it?" The man in glasses ran over panting.

"It's not bad, you can see it yourself."

"...I didn't expect this method to be really good!" The man in glasses looked incredible, "Sir... your thinking is really...awesome."

The man with glasses scuffed for a long time, but he didn't come up with an adjective of "awesome".

“…”

Chen Zheng ignored the man who could not even flatter him. He carried a small instrument and searched up and down the drone.

This small instrument is also a private collection of men with glasses, and was recently searched by Chen Zheng. Its function is to explore the internal structure of the object and form real-time image data.

Before the drone was launched, Chen Zheng had already done a complete survey and mapping, and his data model was saved in the server. After flying once, he re-probe it. After data comparison, he can tell the amount of deformation this time and where the damage occurred.

After flaw detection, Chen Zheng carried the small instrument back to the data center and compared the results of the two flights.

The results are not optimistic.

A large amount of structural damage occurred inside the aircraft, and the rivets in some places were even broken. After analysis, it was found that the result was not due to design problems, but in the power system.

The 450-horsepower electric motor is too rich for this aircraft - just like installing the BMW X6 V8 engine onto a bicycle, the big heart of the car will naturally have problems.

"You are busy, don't be polite if you need help." The girl said.

"Of course." Chen Zheng looked at the comparison data on the screen without looking back, muttering to himself: "Maybe you will need your help soon..."

...

After replacing some accessories and strengthening the structure, the drone took off again.

This time, Chen Zheng did not wait at the scene.

The main purpose of this World War II aircraft was to test a series of data such as remote control systems, homemade servo motors, power systems, structural strength, etc.

These data will become a solid foundation for Chen Zheng to develop the next generation of drones.

Chen Zheng returned to his hut, took out one from a stack of design drawings, and spread it on the table.

On this bark paper covered with carbon lines, it is a weird plane connected by a single-hair, double-body, diamond-shaped wings, and horizontal tail wings. Its shape is somewhat similar to the P38 "lightning", but it is very different.
