Military Industry of Great Powers: Build the Strongest Flanker

"What's Xiao Zhao's upper limit?"

Gao Changming has been thinking about this problem. He feels that there is nothing this boy can't do. What kind of old monster is he!

He thought of Yang Qing and smiled meaningfully.

Look at that boy's clumsiness facing the girl! This is what young people look like.

As for Zhao Guoqing's plan to build a computer-aided chip, Gao Changming has a hundred supporters.

Don’t spend the money of 14 schools.

"Finally doing something serious?"

"What I did before was not serious?"

"……That was not what I meant!"

Well, the most annoying thing for people who are focused on work is to be disturbed. You said that you, a big director, are like a supervisor, so what does it mean to sit on the sidelines?

"Director Gao, can you send a telegram and send someone to bring me the system diagram of the HK-kk517 radar?"

Well, the dignified director has become a handyman.

The principle of the calculation chip of the fire control radar is not difficult. It calculates the distance through the time difference of radar wave feedback, calculates the speed of the target through the phase change of the radar wave, and then determines the accurate position through the direction of the radar scan.

So where is the difficulty?

One is how analog signals are converted into digital signals, and how digital signals are converted into analog signals.

The second is the transmission standard of digital signals.

In fact, the American 1553B transmission bus standard has special regulations for the transmission of radar signals.

The domestic military industry will soon be exposed to this standard.

What Zhao Guoqing wants is to directly skip the 1553B transmission bus and upgrade to the higher bandwidth 1553D modular interface standard bus.

The radar signal is an analog signal and cannot be directly used for logical calculation. It needs to be converted into a digital signal first, and the processed digital signal must also be converted into an analog signal through a special chip.

This involves professional ADC (analog to digital signal) and DAC (digital to analog signal) chips.

The converted digital signal is transmitted to the auxiliary computing chip using the 1553D bus transmission standard, and the calculation results are converted into corresponding control and output analog signals using the same standard.

Zhao Guoqing organized his thoughts, and the next step was demand.

It happened that Director Gao also asked.

"National Day, how many targets can be tracked, how many targets can be attacked simultaneously, and can it catch up with the technical indicators of Mao Xiong?"

"Director, the HK-kk517 radar was introduced in the 1950s. Now it has been thirty years. No matter how backward it is, it is still much higher than the original technical indicators."

The original technical indicator is that it can track three targets and can only attack one of them.

"ten times!"

"call!"

"You said you can track thirty targets and attack ten targets?"

Zhao Guoqing shook his head and said: "Forget about attacking ten targets. Our fighter planes cannot carry so many air-to-air missiles. Also, Director Gao, what are the technical indicators of our air-to-air missiles?"

"..."

It's a bit embarrassing to say that the current common equipment is still the PL-2 air-to-air missile produced in the 1950s, and the PL-3 air-to-air missile installed three years ago.

The Thunderbolt three-air-to-air missile was a project established in the 1960s, and its design ideas are far behind. It uses short-range infrared guidance. Although the range can reach ten kilometers, it originally did not meet the requirements for beyond-visual-range combat.

The reason is very simple. The Pili San air-to-air missile does not have radar guidance function, so it cannot use over-the-horizon radar guidance or short-range infrared guidance mode.

Gao Changming shook his head and said: "National Day, currently our fire control radar can only be used for cannon locking and close combat. As for the Pili series of air-to-air combat radars, it is only a launch-and-forget infrared guidance."

"Even if it can attack ten targets, there are not enough cannons!"

Zhao Guoqing shook his head. Domestic air-to-air missile technology has lagged far behind.

Gao Changming, on the other hand, frowned, wondering whether he should speak out about a study that 14 institutes were participating in.

"You can't do it with nothing, but you can use ground and space. Director Gao... Hey, Director Gao, where are the people?"

Without demand, there is no design. An important part of the fire control system is communication with the missile.

If there are no suitable air-to-air missiles, how can we communicate?

How is data transfer performed?

…………

Gao Changming walked out of the guest house and went directly to Z Airlines headquarters.

According to normal procedures, Chengdu Aircraft is a unit under Z Airlines, and 14th Institute is a unit under Chengdu Aircraft. No matter how hard the 14th Institute reports its work, it cannot be reported to Z Airlines.

But things take their own course.

14. To bring out the top-secret information within 14, not to mention the complicated procedures, the escort procedure is even more disappointing.

It's much easier from Z Airlines.

"Changming, why are you here? Are you coming to Beijing for a meeting? You have some conscience!"

Gao Changming expressed his intention directly.

"Guoqiang, I'm here to ask for your help!"

"..." Liu Guoqiang said: "Changming, just tell me directly, what is there that our old classmates don't want to talk about!"

"It's urgent, I want to check some technical information on the Falcon Strike project!"

Liu Guoqiang smiled and said: "I thought it was something. This does not violate the regulations. You 14 have this authority, but there is one thing. It can only be used within Z Airlines and cannot be borrowed!"

"I want to bring someone with me!"

Liu Guoqiang looked at Gao Changming and frowned.

Gao Changming smiled knowingly and said: "The person inside our 14th Institute is called Zhao Guoqing, and this is his ID!"

Liu Guoqiang took Zhao Guoqing's ID and looked at it, shook his head and said, "Changming, you understand discipline. No matter who enters this project, they will be re-examined!"

"You!" Gao Changming shook his head and said, "If Director Liu of the General Assembly Office guarantees it, can I go in?"

This is equivalent to a post-qualification review.

In front of Liu Guoqiang, Gao Changming called the confidential telephone number of Director Liu Qing's office, and Director Liu Qing happened to be there.

"Chang Ming, why are you in B Beijing? Didn't I tell Xiao Zhao that if you come to the Magic City, the Academy of Sciences can also do it!"

"Director Liu, Guo Qing said there are other things!"

Seeing it through but not telling it off, Xiao Zhao said that the General Assembly Office was cheating 14 of them. Although Gao Changming did not completely agree, at least he still felt that way in his heart.

"How did things go?"

"Everything went well. By the way, Director Liu, I have something to report to you!"

"Chang Ming, if you have anything to do, just say it directly!"

Gao Changming thought for a while and said, "National Day has some ideas about fire control radars. I want him to participate in the Falcon Strike project. What do you think?"

"Okay, you 14 can decide this matter. Why did you call me?"

Gao Changming said: "That's it, Director Liu, we are at Z Aviation now and need to access some Falcon Strike project information. We need you to say hello!"

"Then you have to tell me, what is that boy going to do?"

…………

Gao Changming talked for a long time and handed the phone to Liu Guoqiang. Liu Guoqiang took the phone, talked for a while, hung up the phone, looked at Gao Changming, and complained: "You are just watching my joke!"

"No way, Guoqiang, I'll do something first, you can arrange a car for me, and I'll treat you to dinner later!"

"Okay, when it comes to your territory, you have to make arrangements. Listening to you say that, my hands are a little itchy!"

"Haha, we will arrange for you to go hunting in the mountains. Institute 14 welcomes you to come and inspect the work!"

When Gao Changming returned to the guest house, he picked up Zhao Guoqing and went directly to the Z Aviation Laboratory Building.

"Director Gao, what are you doing?"

"You'll find out later!"

This is a secret small building with only three floors. There are soldiers inside and outside. People are searched when entering and exiting. After entering an empty room, someone soon brought a pile of documents.

Zhao Guoqing was stunned when he opened the catalog.

It turned out to be the technical data of the Jewish Snake 3 air-to-air missile.
