The Immortal Warrior: From Reverse Engineering to Forging Swords for the Country

Chapter 74 Next target: aircraft engine!

After accepting the pulse Doppler fire control radar, Zhao Bingkun talked with Zhang Zhipeng.

Because Zhao Bingkun noticed the discussion about phased array radar in Zhang Zhipeng's paper.

What he discussed was the combination of phased array radar and Doppler pulse radar, taking the advantages of both, making radar detection more accurate, faster, all-round, and able to detect longer distances.

This point deeply attracted Zhao Bingkun.

Phased array radar is actually nothing new.

It appeared in the 60s.

The original function of this radar was actually to warn of intercontinental missiles.

Because the detection distance it detects is quite far, thousands of kilometers.

Belongs to true clairvoyance.

However, this thing was quite huge at first and could only be installed on land or on ships.

But since the 90s, with the development of technology, phased array radars have begun to become miniaturized.

The so-called phased array radar is a phase-controlled electronically scanned array radar. It is a radar area array composed of a large number of identical radiating units. Each radiating unit is independently controlled by wave control and phase shifters in phase and amplitude, and can obtain accurate Predictable radiation pattern and beam steering.

Of course, China also needs a large phased array early warning radar.

In fact, as early as 1978, our country developed and manufactured the first phased array radar. This thing was eight stories high and had a scanning and detection range of three to four thousand kilometers.

Phased array radar and pulse Doppler radar actually have their own advantages and strengths.

In Zhang Zhipeng's paper, he analyzed these technological innovations such as integrating these two radars and designing a unique antenna array to achieve the miniaturization of the phased array.

Moreover, he has already drawn schematic diagrams of the design in his paper.

Zhao Bingkun chatted with Zhang Zhipeng, mainly about Zhang Zhipeng's idea.

"Zhipeng, I think your idea of ​​merging phased array and Doppler radar has great practical value."

"How about you work on such a subject?"

Zhao Bingkun didn't mince words, he simply told Zhang Zhipeng his purpose.

Zhang Zhipeng smiled and said: "Director Zhao, I have no problem taking on this project."

"The key is, I think, domestic aircraft engines are more important now!"

Zhao Bingkun was stunned for a moment.

Then his eyes sparkled with excitement.

"Oh?! So, do you have any ideas about overcoming this problem?"

Aircraft engines are truly the crown jewel of technology!

There may only be three or four countries in the world that can produce the most advanced supersonic fighter engines.

Robin counts as one, Da Mao counts as one, and John Bull counts as one.

The aircraft engine of Gallic Chicken is pretty good, but compared with the above three, it is just a little bit behind.

The five gangsters, in fact, only China cannot produce its own high-performance aircraft engines.

Zhang Zhipeng nodded and said, "I became very interested in aircraft engines when I was helping my tutor develop avionics systems."

"Currently, 105 is mainly responsible for the engine, right?"

Zhao Bingkun smiled and said: "Yes, 105 is mainly responsible."

"However, other research institutes are also proceeding simultaneously."

"Aircraft engines are so important."

"We can't keep our treasures in one place!"

Zhang Zhipeng said: "How about I combine it with Institute 105?"

"I don't want to take their jobs either."

"I just want to get the engine out as quickly as possible."

Zhao Bingkun said: "The most important bottleneck of the engine at present is actually a material problem."

"We currently cannot produce single-crystal blades. And if this thing cannot be produced, the engine's turbocharging performance will not be fully exerted."

"You know this, right?"

Zhang Zhipeng nodded and said, "I know. In fact, there are four major difficulties in the research and development of aircraft engines."

"First of all, the first is the extremely high requirements for safety and reliability; the second is the single-crystal engine blades; the third is how to solve the cooling problem of the turbine blades; and the fourth is under the impact of violent airflow. Maintain stable combustion in the combustion chamber..."

Zhang Zhipeng talked about the solutions to these problems. Of course, these solutions were all figured out after he had improved his aero-engine design and development skills to the highest level with the help of the system.

Although Zhao Bingkun doesn't understand these too professional things.

However, Zhang Zhipeng talked very plainly.

He can understand it!

Zhao Bingkun said with a smile: "Although I don't understand much, I think what you said makes sense!"

"How about you write a series of papers? I'll organize experts to discuss it?"

Of course Zhao Bingkun understands what aircraft engines mean to China!

If the engine can be developed earlier, then the military strength of the Chinese Air Force will be greatly improved!

This is very important!

Because, Robin has always relied on air superiority to harass me from time to time!

Zhang Zhipeng nodded and said, "Okay! Then I'll go back and summarize my ideas!"

"I try to be as detailed as possible and use pictures to show my technical solutions."

Zhao Bingkun nodded happily and said, "Then it's settled!"

"I can't wait to see your masterpiece, haha!"

Zhang Zhipeng said: "We will strive to solve the problem of aircraft engines in 1991!"

"If this hurdle is overcome, I think our fighter jets can be updated and iterated quickly. What do you think?"

Zhao Bingkun smiled and nodded and said, "That's true."

Zhang Zhipeng seemed to have stayed in Institute 607 for a total of twenty-seven or eight days.

When he left, Chang'an City was still freezing.

By the time he came back, the city was already feeling a bit like spring.

As soon as he came back, principal Dong Haoming and his secretary Qian Yizhou came to see him in person. Qian Yizhou also had a big bag on his shoulder. The bag was so stuffed that he didn't know what it was.

"Zhipeng, you are finally back." Dong Haoming said with a smile.

Zhang Zhipeng smiled and said, "Does the principal seem to have something urgent?"

Dong Haoming said: "You have brought glory to our school!"

"Five of your papers on radar have been published in top domestic journals."

"Many teachers may not be able to publish one article in their lifetime!"

"You posted five articles in one go."

As Dong Haoming spoke, he asked Qian Yizhou to take out a pack of academic journals exuding the fragrance of ink and hand them to Zhang Zhipeng.

Zhang Zhipeng looked through it and found that all five of his papers were shown on the covers.

This indicates that it is the focus article of this issue of the magazine.

However, the signatures of his articles are all pseudonyms, called "Long Changzhi".

He chose this name himself.

The author's affiliation is indicated as NPU, but the detailed affiliation is not indicated.

This is also to conceal Zhang Zhipeng's identity.

"Zhipeng, you have written this series of articles well! I heard that you have developed a domestic pulse Doppler radar?" Dong Haoming said with a smile.

Zhang Zhipeng smiled and nodded: "Fortunately, the mission has been fulfilled! It has been done."

“The performance in all aspects is not inferior to the most advanced similar foreign products.”

"Our airborne clairvoyance problem has been solved."

Dong Haoming smiled and said: "Great!"

"In this way, the fighter's beyond-visual-range combat capabilities are guaranteed, haha!"

Dong Haoming smiled very happily.

Zhang Zhipeng nodded and said: "With this domestic pulse Doppler fire control radar, there should be no problem beyond visual range."

"We don't need to ask for the hoopoe anymore."

Dong Haoming gave a thumbs up: "This is more fulfilling than publishing a paper!"

Dong Haoming had another conversation with Zhang Zhipeng, and he brought some good news to Zhang Zhipeng.
