Chapter 259 The start of metal hydrogen batteries is a step towards the future

From Houston's perspective, it is impossible for China to solve the strategic bomber's flight control problem in a short period of time, but in fact, even without considering Chen Nian's latest plasma device, the H-20's flight control system has already reached fully usable standards.

.

After all, after more than two decades of evolutionary development, the originally complex flight control system of the B-2 has become relatively simple due to the development of electronic and intelligent technologies.

The technologies provided by the system are mature and stable, and are much more practical than B-2's technology.

Now, with the blessing of plasma devices, the mobility of the H-20 is bound to go to a higher level.

It is even possible that it will become the most maneuverable strategic bomber after the Tu-160.

No. 603, in Tang Changhong's office.

Chen Nian explained his plasma design while flipping through the information.

"The essential principle of a plasma device, or plasma jet exciter, is to generate a high-energy jet through spark discharge, which is ejected from the top of the device, thereby improving the leading edge separation flow under large-angle maneuvers."

"In this process, discharge frequency and intensity are the most important factors affecting flight control."

"So, the main problem for us in manufacturing this type of device is to determine the electrode material and the power supply."

"According to my design, the plasma device should use an asymmetric layout. The insulating medium is a polyimide film, the discharge electrode is made of copper foil, the width of the embedded electrode is 5mm, and the rear edge of the embedded electrode and the front of the exposed electrical appliance are

Connected by fate.”

"As for the power supply, use a microsecond pulse power supply, set the half-pulse width to 25 microseconds, and the peak pulse power should reach more than 4.5MW."

"For force measuring devices, you can use a rod-type six-component balance, and the response frequency should be greater than 80Hz."

Listening to Chen Nian's words, Tang Changhong nodded repeatedly while recording.

When he first saw Chen Nian's design, he thought that the other party would only provide directional guidance. At most, it would explain the principles clearly and clarify the key points, just like he had previously provided basic technical guidance for the H-20.

But I didn't expect that this time he provided technology that was complete to the parameter level!

Finally, I can enjoy the legendary nanny-level service.

You know, during the previous manufacturing process of the J-22, he had heard Lei Gang tell the legend about Chen Nian many times.

He has always been amazed at how such an "individual" can complete a job that hundreds or even thousands of people took several years to complete, and he has always wanted to have the opportunity to experience it.

But now, I finally feel it.

Although it is just a small plasma jet excitation device.

But although the device is small, it does not affect its "user experience" at all.

And this experience is really great

You don't even need to think about it, everything is just right in front of you.

The only thing you have to do is to build the thing according to the guidance of the documentation and parameters.

Isn't it possible that I can't do this little thing well?

——

Of course, Tang Changhong was not completely without doubts in this process.

Regarding the issue of discharge frequency, he repeatedly confirmed it with Chen Nian many times.

But no matter how tricky or detailed his question is, Chen Nian can answer it without hesitation, and also provides some analysis of the principles.

".So in summary, if the discharge frequency is less than 70Hz, the lift coefficient of the whole machine will increase with the increase of discharge frequency after excitation is applied at a large angle of attack. If the discharge frequency is greater than 70Hz, the lift coefficient of the whole machine will decrease with the increase of discharge frequency.

The aircraft lift coefficient increases the most when the discharge frequency is 70Hz."

"In this case, we also need to establish an additional control system to combine with the flight control sensing device to control the plasma device."

Chen Nian finally finished explaining the entire contents of the plasma device, while Tang Changhong's face across from him had a look of sincerity written all over it.

“That’s awesome!”

He said sincerely.

"Gong Chen, your skills and knowledge reserves are truly unprecedented."

"I have been in this industry for so long, and I have never met someone as exaggerated as you."

Hearing his words, Chen Nian smiled shyly, and then replied:

"It's nothing to me. If you can build the H-20 with bare hands, that's really awesome."

"After all, for such a large and complex aircraft, the process from zero to one is the most difficult."

"That's really not that difficult!"

Tang Changhong quickly waved her hand.

It’s a joke, you have already mastered the key technologies, and you still say that our job is the most difficult. Isn’t that making us miserable?

"Actually, it's just some practical work. It doesn't matter whoever does it."

"The biggest contribution is from your side, Mr. Chen."

"It's better not to call me Chen Gong, just Xiao Chen."

Chen Nian interrupted.

He was really not used to what Tang Changhong called him. After all, in his heart, Tang Changhong was still the "Father of Kunpeng".

Regardless of the system's bonuses, people of this generation like Tang Changhong have always been unquestionable in their hearts.

"Forget it, Xiao Chen. Just like Lao Yang, let me call you Xiao Nian."

Tang Changhong laughed and continued:

"Xiao Nian, how long do you plan to stay here specifically this time? Are you going to be fully involved in the follow-up work?"

Chen Nian nodded and replied:

"Yes."

"From today until the H-20 test flight is successful, I will stay at 603."

"Of course, it's not because you didn't do a good job, it's because there are some other reasons. We must ensure that the H-20 completes its test flight as soon as possible and forms combat effectiveness."

"So, I want to help you eliminate some risks that may arise in the process by stepping in myself."

"clear."

Tang Changhong tapped her fingers lightly on the table. After thinking for a moment, she said:

"At this stage, it is indeed a period when risks and problems are high."

"In terms of flight control, with the plasma jet device, the robustness of the entire system will be greatly improved, and there will basically be no problems in the future."

"The main thing we can think of is probably the problem of the cabin structure."

"As for radar and electronics, you may still want to check with the 14th Institute. We plan to equip the H-20 with a digital array radar. It is said that they have optimized its performance."

"Then the last one, which is also the most difficult one, is the variable cycle engine. Institute 606 is making rapid progress, so I guess the problem won't be too big - they have experience after all."

After Tang Changhong finished speaking, Chen Nian pondered for a few seconds, and then asked:

"What about the stealth coating? Is there anything wrong with it?"

"The feedback from the Material Research Institute is that there is no problem - wasn't a small amount of graphene material used on the J-22 before? Now it has basically been mass-produced and will be used on the H-20."

"That's no problem."

Chen Nian let out a long sigh of relief.

If the situation mentioned by Tang Changhong is correct, then there really won’t be too many difficulties in the progress of the H-20 project.

What you have to do is to keep an eye on the process to avoid uncontrollable risks in the future.

After leaving Tang Changhong's office, Chen Nian returned to his residence in House 603.

In the room, he checked the accumulation of source points in the system again.

The plasma jet excitation device did not consume him many source points. So far, he has accumulated 27 source points.

Moreover, the number of new source points added every day has also remained at 0.35 points.

In other words, the daily growth number of source points has reached the lower limit.

This is all the result of technological fission achieved by previously exported technologies.

On the other hand, the study of new energy materials has been basically completed, and the next step is to usher in the real practical stage.

We are one step closer to solving the new energy problem

Chen Nian once again tried to analyze the previously optimistic Amprius lithium battery, and this time, the analyzed source point consumption has dropped to 16 points.

Compared with two months ago, the source point consumption has dropped by 4 points.

There is no doubt that this is a reward for his hard work during this period.
