Hang Yucheng opened the file bag and took out the information inside one by one to look at it carefully.

Pneumatic layout design scheme, general layout design scheme, overall structure design scheme, system design, material process cooperation requirements......

The plans and materials to be demonstrated were placed in the document bag, and the sophistication of these materials was somewhat beyond Hang Yucheng's expectations.

"If you just looked at these documents, I thought you had designed a helicopter before!" Hang Yucheng said to Chen Shen.

Compared to the rough documents he read yesterday, the materials today are much more complete, and they have everything they should have, so to speak, and all aspects of the design have been taken into account.

At this time, Hang Yucheng realized that Chen Shen was really not fooling, looking at these documents, he came prepared!

Chen Shen smiled, "It's all the experience I learned from the Crimson Storm project. ”

Hang Yucheng looked at the document and sighed: "The experience learned from the mecha project can be used in the helicopter, and you are also ...... power."

At the beginning, Hang Yucheng could still talk to Chen Shen with a smile and a smile, while looking at the document, but the more he looked down, the more serious his face became, and he didn't say a word in the end.

It wasn't until he read the first three plans that Hang Yucheng asked in surprise: "Have you completed the conceptual design part?" ”

"What conceptual design?"

Chen Shen, who lacks serious work experience, has no idea what these terms mean.

Hang Yucheng explained: "You have completed the preliminary technical plan of the helicopter? ”

Hang Yucheng also knew that Chen Shen had this problem, Wang Qian had already told him before, which was also an important reason for sending him over, so he simply explained the entire design process of the helicopter.

Conceptual design in the helicopter design process is generally after the technical demonstration, simply put, to determine what kind of technology to use in the helicopter, what kind of shape can achieve the expected indicators, and at the same time, the helicopter size and weight and other detailed parameters will also be formally determined at this time.

After completing this step, you can build a corresponding blowing model according to the design and throw it into the wind tunnel for blowing test, and then calculate and modify the maneuverability, stability and even flight center of gravity of the aircraft according to the feedback.

The next step is to fully achieve the expected design indicators in the modification, and submit all the drawings and technical documents required for the prototype trial production for approval, and then hand over to the trial production plant for production.

Then it is the matter of trial production of the whole machine, generally the number of trial production of the whole machine is three to five, and the ground and air tests will be carried out after the production is successful.

If no problems are found in these tests, the production drawings, technical documents and prototypes can be handed over, and the recommendations for use and maintenance can be made, and then the production can be officially started.

The formation of the preliminary technical scheme in Hang Yucheng's mouth is a sign of the completion of the conceptual design.

As soon as he said this, Chen Shen understood.

"According to you, then I have indeed completed the technical plan, and it is estimated that it will not be long before we can go to the wind tunnel." Chen Shen touched his chin.

He had just seen the progress of the Eagle Helicopter project suddenly increase by another 1%, which is estimated to be the credit of the official announcement of the "Pacific Rim" project.

Hang Yucheng quickly flipped through the rest of the documents, and found that as Chen Shen said, this was indeed a completed technical plan, and the design framework had been built, just waiting for them to fill in more details.

Hang Yucheng smiled bitterly, "Your movements are too fast, so let the team calculate and demonstrate this technical solution again." ”

Hearing his words, Chen Shen shook his head: "This plan doesn't need to be demonstrated, according to my calculations, there is no problem, let's let everyone do something more meaningful." ”

Rather than letting the toolman's labor casually waste on this kind of system and the things he has already verified, it is better to let Hang Yucheng take the toolman to do other work.

"Other work?" Hang Yucheng was stunned for a moment.

"Uh-huh," Chen Shen thought for a moment, "such as the avionics system." ”

Although the technology of the system is very good, it is a common thing to adapt to the water and soil, and many modules in the avionics system need to be transformed according to the actual situation in China.

If it is built according to the technology of the system, it is like taking an alien mobile phone to the earth and delusionally believing that it can provide services.

These systems that need to be localized should be designed at this time, and they should be able to test them in time for later.

"In addition, the aerodynamic shape of the aircraft can also be modified if you have time." Chen Shen specially mentioned it.

Hang Yucheng looked at the helicopter shape on the plan, which was very similar to Chinook, and agreed to come down with sweat.

When Chen Shen said that he wanted to "imitate" Chinugan, he didn't care about it, but now that he really remembered it, he directly built it according to the appearance of the helicopter opposite, which was a bit too arrogant.

Although the interior of the two helicopters is completely different, but the appearance is so similar, maybe there will be trouble such as appearance patents, so he also thinks it is better to change it for the sake of insurance.

"So how are we going to change that?" Hang Yucheng asked.

Chen Shendao: "As long as you can avoid the appearance patents that the other party may have, you have to pay attention to it, don't completely change the appearance characteristics of Chinook." ”

He thinks the same as Hang Yucheng, but he has a lot less scruples, as long as the other side can't be followed, he will be disgusted and how to come.

"The ...... that aerodynamic shape will affect the performance of the helicopter," Hang Yucheng had to remind.

"It's okay," Chen Shen waved his hand, "As the saying goes, the power is great, as long as you don't change it into a big square, in the case of strong power, you won't be able to reduce your performance." ”

Although Hang Yucheng always felt that something was wrong, he still nodded and agreed.

Next, Chen Shen began to arrange other work that needed to be localized, and when the arrangement was completed, Hang Yucheng left the conference room with a full of documents and materials, ready to implement.

Chen Shen received a call from Ma Zhen, who told him that the brain-controlled exoskeleton system designed by He Anshou had been completed, and asked him to see what else needed to be improved.

As soon as Ma Zhen reminded him, Chen Shen remembered this matter.

A friend of his father's had his limbs amputated due to an accident and asked him to help develop a brain-controlled prosthetic system.

In addition to participating in the design of materials, power supplies and some structures, Ma Zhen is responsible for other parts.

Now it seems that it is done.

Thinking like this, Chen Shen found a driver and drove to the scientific research center.
