The military-industrial scientific research system of the academic master

The old guy mentioned by Dean Ji is naturally Du Yishan.

And the old man’s student is undoubtedly Chang Haonan.

In normal times, this kind of cooperation is not particularly complicated even if it is conducted across schools. It is just that there will be some entanglements in the ranking of final results and contributions.

But the problem is that the two people in the research group, Chang Haonan and Yao Mengna, who are the best at numerical simulation, are already highly bound to the 83rd Project.

They are even dealing with the problem of turbojet 14 engines now.

Since Yao Mengna's research on compressor blade slits was conducted privately, no one else knew that the unremarkable article published in Aerodynamics had entered her field of vision, and it must have been very Soon they will enter the vision of Chang Haonan and Yan Zhongcheng.

Du Yishan quickly found Liu Zhenxiang, who had been working in the field of aviation power for many years.

Although the latter's research focus in the past ten years was actually aero-engine testing simulation equipment rather than the aero-engine itself, he quickly saw the potential of Yu Fei's research direction.

Of course, the word potential alone is definitely not enough for Yu Fei to directly join the 83rd Project.

Even with Du Yishan's personal recommendation, Chang Haonan passed the review by solving the wing flutter problem for the MA60 and became a member of the core circle of the entire August 3rd Project. .

You know, the day after he and Yao Mengna arrived in Shengjing, they were led by Lin Shibuan to participate in the project progress seminar.

This kind of meeting seems to be very frequent and inconspicuous, but there are still only a few people who can actually attend it.

Even many engineers from Institute 601 or Institute 606 who were not deeply involved in the August 3rd Project did not have such a high right to know.

Therefore, after discussing it for a period of time, Du Yishan and Liu Zhenxiang decided to let Yu Fei participate first as a peripheral researcher.

In other words, he can cooperate with Chang Haonan (or Yao Mengna), but he will not join the project team for the time being. Confidential information above a certain level involved in the scientific research process needs to be declassified before it can be sent to him.

…

Although Project 83 is advancing at an unprecedented speed, some things will come faster.

The 5th Radar Regiment of the East China Sea Fleet Aviation Force.

"Report to the battalion commander that the signal has appeared again!"

A radar soldier shouted excitedly behind him.

The major officer who was resting on the table suddenly woke up when he heard these words, rubbed his bloodshot eyes, and came behind the radar soldier.

On the circular display of the early warning radar, an echo signal lingering about 150 kilometers away from the coastline appeared.

"Still not turning on the transponder?"

An aircraft transponder is an electronic device mainly used for air traffic control. When it receives a radio interrogation signal, it automatically responds so that secondary radar on the ground can learn the position of the aircraft.

According to regulations, civil aviation aircraft must turn on their transponders when flying in the air.

"No, and it's still on the route that appeared several times before."

This is not the first time this strange plane has appeared.

Based on the battalion commander's experience, even with such an old-fashioned radar, he was able to determine that it should be a Boeing 707.

And the previous few times, it had flown on the route from Tokyo to Manila in an orderly manner. Except that the transponder was not turned on, its performance was no different from that of a commercial airliner.

Of course the radar battalion commander also considered the possibility that this was a reconnaissance aircraft.

After all, it is a common tactic of the NATO air force to disguise a reconnaissance aircraft as a passenger plane, or to use fighter jets to cover it. In most cases, the reconnaissance party does not have the guts to fire on such a target.

However, the P3C that is common near the eastern sea area cannot fly at this speed, and the E3 early warning aircraft or RC135 reconnaissance aircraft have obvious changes in appearance, and the echo signal will be larger.

The battalion commander really couldn't think of anything else besides a Boeing 707.

Therefore, their superiors just asked them to pay more attention and report back if there was any abnormal behavior on the plane.

Of course, for similar situations, the safest way is to take off a fighter jet for visual tracking and confirmation.

In this way, the situation can be accurately identified and emergency measures can be made to deal with unexpected situations that may occur.

Such as driving away or disturbing.

But for the aviation units in the 1980s and 1990s, even a seemingly simple matter such as an emergency takeoff in the face of air conditions was not easy to organize.

Whether it is aircraft readiness rate, pilot experience or the ability level of ground handling units, they will limit the speed of aircraft dispatch.

Of course there is another important reason, money.

The aviation force does not have enough funds to maintain 1-2 aircraft in a hot state on standby at any time.

Therefore, by the time the aircraft is ready to take off, the target aircraft is already far away from the coastline.

But today, the situation has changed somewhat.

"Batalion Commander, the plane has deviated from the route." The sharp-eyed radar soldier was the first to discover the anomaly in the target position on the display:

"It seems to have lowered its flight altitude, and then... started to turn back?"

"This is not turning back..." After all, the battalion commander is well-informed. He knows that this zigzag route is either anti-submarine or reconnaissance.

Obviously, it is impossible for an aircraft to conduct anti-submarine warfare at an altitude of 9,000 meters.

"Keep your target in mind, I'll report to my superiors!"

The battalion commander took out the military cap from under the rank on the shoulder of the camouflage uniform, put it on his head, and then quickly ran out of the command room.

In this era where even the concept of flat command is immature, the chain of command under normal circumstances is quite complicated.

Fortunately, it was not the first time that plane appeared, and the aviation force of the East China Sea Fleet had made some preparations to deal with it within its capabilities.

The plane had been hovering near that location.

It's just that every time you make a 180° turn, you will get slightly closer to the coastline.

This gave naval aviation units an opportunity.

About twenty minutes later, two J-7HH fighter jets, each carrying a PL-8 air-to-air missile, took off one after another and flew quickly towards the eastern coastline.

The J-7HH is actually a J-7B that can carry PL-8 missiles and has been improved to cope with use in high-salt environments.

Radar, of course, does not exist. Pilots can only rely on a pair of eyes to search for targets, and are highly dependent on ground command during combat.

As for the early warning radar in the VHF frequency band, the detection range is far enough and even has certain anti-stealth capabilities, but the detection accuracy is indeed not ideal.

In addition, there is no data link, and relying on voice guidance itself has errors.

Therefore, after guiding the two J-7s to the target, the remaining work can only be done by the two pilots themselves.

Fortunately, they were lucky today.

The weather was sunny and cloudless, and the sun was in a favorable position.

After conducting a search for about 10 minutes, wingman pilot Chen Haisheng suddenly saw the dazzling reflection of the metal skin under the light at the low 8 o'clock position of his aircraft.

"I saw!"

About the update:

I've been on a business trip these days, so I can only update twice a day for the time being. There should be another wave of updates after I go back next week.

In addition, I am considering whether to consolidate the update time around five o'clock in the afternoon.
