Black technology: I can decompose everything

Chapter 100 is all completed (seeking the first order! 55)

Professor Du kept stroking the rotorcraft with his hand, then looked at him sincerely, seeing how embarrassed he was and continued.

"Look at this gyroplane from your hands, have you thought about what will happen to it afterward?

I said that this small plane is just the beginning. Think about it, if you come with me, the silver war eagle flying over the motherland is very likely to be in your hands in the future. Isn’t this more meaningful than learning computers now?
Our aviation industry is not strong. I really hope that young people like you will join the aviation industry and contribute to the prosperity of the aviation industry.

I also know that it's hard for you to make a decision right now, so think about it carefully, and I'll wait for your reply, Zhenhua! "

Li Zhenhua is really conflicted in his heart now, he really doesn't know what to do, his mind is a mess.

"Professor, let me think about it carefully. I really haven't thought about these things. I will give you an answer when I think about it!"

His answer did not exceed his expectations. After all, what he said could be regarded as a turning point in his life. If Li Zhenhua accepted his invitation now, Professor Du would not be so relieved.

Professor Du patted him on the shoulder again, and said to him very warmly: "Okay, don't think about it for now, you can go to the militarized modification of the rotorcraft, and we will talk about everything after we finish the exhibition!"

After finishing speaking, Professor Du walked away alone, leaving Li Zhenhua standing still thinking about what he just said.

'Boy, I don't believe you can run! '

But Professor Zai Du walked away from Li Zhenhua, but there was a smile on his face, like a weasel who successfully stole the chicken.

Professor Du walked away in a good mood, but he left Li Zhenhua who was entangled, but he only tangled for a while, because this matter is not something that can be decided in a short time. After thinking about it Let's keep an eye on the military modification of the rotorcraft.

As far as the entire school of Beihang University is really strong, Li Zhenhua talked with the professor last time, and it has only been six days since the rotorcraft has entered the final assembly stage.

After the colleges received his design drawings, under the leadership of the professors of various disciplines, they entered the substantive manufacturing.

It is also because of the manufacturing experience of the three rotorcrafts before, this time it can be said that the manufacturing is very familiar, and there is not even a single problem.

Of course, the scale this time is not as outrageous as last time. This time, only manufacturing-related disciplines have been added. For example, the School of Materials did not participate. Even if they wanted to participate, the school leaders probably would not let them participate. came in.

Li Zhenhua came to the School of Engineering early in the morning, and a huge laboratory was now fully occupied by three rotorcraft that were being manufactured.

The gyroplane that is being manufactured has already begun to take shape, and the chassis has already been welded. Several students from the engineering school are installing a naturally aspirated horizontally opposed engine in an orderly manner under the command of the instructor.

This engine is Li Zhenhua's upgraded and modified aviation engine based on the twin cylinders, and it still uses a horizontally opposed layout.

However, this engine does not use a turbo system, and it has two more cylinders than the previous one, and the total displacement has reached 1.5L.

Although there is no turbo air intake, the air intake volume is much smaller, which reduces the single-cylinder horsepower, but it can't stand the two more cylinders on the whole.

As the displacement increased, the horsepower also increased. After the engine was assembled on this day, a professor from the Aerospace Design Institute took the lead in conducting some actual measurements.

The final data is more than enough to be used on the rotorcraft, the total displacement: 1496, the air intake form: natural aspiration + impact air intake, the engine mechanism: horizontally opposed, the number of cylinders: four cylinders.

Cooling method: air cooling, maximum horsepower: 201ps, maximum power 147kw...

This four-cylinder aviation engine has a horsepower of 200 horsepower, and the corresponding weight is 30 kg heavier than before, but compared with the horsepower obtained, this is completely worth the money.

Although the horsepower that each cylinder can provide is only 80% of the previous one because of the removal of the turbo intake, the horsepower directly exceeds 200 with two more cylinders.

With such a powerful aviation engine, I believe that the performance of the final rotorcraft will be improved to a higher level.

The aviation engine weighing 110 kg was successfully fixed on the engine position of the rotorcraft under the operation of several students.

At this point, the gyroplane in front of Li Zhenhua actually has no outer casing installed. Even in its current state, the gyroplane can be directly driven into the sky.

Certainly compared with the gyroplane that conforms to the aerodynamic shell, the full performance of the gyroplane cannot be brought out.

If you go to the sky like this, then the overall data will be weakened by 30%. Don’t forget that there is a short-term road design for aviation engines on the shell. It will intervene in the operation of aviation development.

Although it is said to be a naturally aspirated engine, in fact Li Zhenhua still has his own unique innovation.

After the aviation engine was installed, the professor led the group of students to leave the arena, and then the next wave of students came in to take over, and soon all the remaining parts of the rotorcraft were installed on the plane.

In the afternoon, after a busy day of assembly by the students, the three gyroplanes were finally assembled. Don't look at it, it looks like a farm vehicle, but he can fly if he can't stand it.

If there is anything that is not installed now, the only thing left is the propeller above the head that has not been installed.

At this time, there are only four days left before the start of the internal exhibition. Excluding the time for them to be transported to the International Village and the time for preparation, there is only less than two days left when they are fully paid. They make the final test flight.

I have to say that Li Zhenhua's speed this time is quite fast. Of course, this is inseparable from the strong support of other colleges in the school. But at this moment, Li Zhenhua doesn't know how to proceed.

As for the reason, it is easy to understand, but don’t forget where the school of Beihang University is located. This is the capital of Beiping, and the control of any aircraft is quite strict.

If you want to conduct a test flight under the foundation of the imperial city, this is really not something that Li Zhenhua, a freshman, can handle. It seems that the next thing can only be counted on Professor Du Sanyi.

Thinking of this, Li Zhenhua searched for Professor Du on the spot. Sure enough, he only took a few glances, and soon he found Professor Du who was talking to a professor.

Then they pulled Wei Jiayang, who was still drooling while touching the weapon rack of the rotorcraft, and the two leaned towards Professor Du.
