Back in 1978, I was admitted to Northwestern Polytechnical University.

Chapter 447 J-9 Finalized, Participates in Military Parade! Does the J-8 Want to Do It Too?

Flight Test Center.

A beautiful fighter jet stands at the end of the runway, with its nose up, air intake under its belly, canards on top, main wings behind, and a waistline that retracts at the rear of the fuselage. Combined with its tall vertical tail, this aircraft is pleasing to the eye no matter how you look at it.

"Distinguished leaders, welcome to the Flight Test Institute. Our J-9 fighter jet has completed all its flight test subjects. Today's main event is the type certification demonstration. Please enjoy the performance," Director Zhou reported excitedly to the Air Force leaders.

"Yes, we've seen a lot of advanced equipment. F-16s, Mirage 2000s... Our J-9's flight demonstration can't be worse than those planes!" Old Lin said with a smile, raising his requirements.

"Of course we won't let you leaders down," Old Song said. "The performance of this aircraft is absolutely the strongest among third-generation medium-sized fighters, without exception!"

"Alright, let's wait and see!"

Qin Liang looked around, and then... he saw a test pilot carrying a flight helmet walking over from the control tower.

"Lei Zi?"

"Comrade Qin Liang, you've come too?" Lei Qiang was very excited.

"Yes, the J-9 has been finalized. This is of great significance, and I have to come and see it."

Although there have been quite a few aircraft before, such as the J-7, the twin-engine Q-6, and the JF-17, Qin Liang still values ​​the J-9 the most, after all, it was developed as the main third-generation fighter jet of the Air Force! It will be equipped in large numbers in the future!

"Yes, don't worry. This flight demonstration will fully showcase the J-9's maneuverability, including many high-G maneuvers. I'm the youngest and in good physical condition, so everyone let me fly!"

"Alright, let's go up there quickly and broaden our horizons!" Old Lin came over and patted Lei Qiang on the shoulder.

Lei Qiang stepped into the cockpit, and a minute later, a roaring sound began.

Orange-red flames shot out, indicating that the afterburner was activated, and the fighter jet rapidly took off under everyone's watchful eyes.

One hundred meters, one hundred and fifty meters...

The front landing gear has actually been raised!

Two hundred meters... the main landing gear behind also lifted up, and the fighter jet left the runway, followed by the nose of the aircraft turning up.

Thirty degrees, forty degrees, sixty degrees, eighty degrees...

Every time I see this steep climb, I am filled with awe. It's amazing how powerful it is! Our Eastern aviation industry can finally have such a luxurious day!

Moreover, eighty degrees, that's even stronger than last time!
"Has the thrust of the WP-15 turbojet engine been increased again?" Qin Liang couldn't help but ask.

Aside from the drawback of turbojet engines being fuel-intensive, almost everything else is an advantage. For example, the thrust of the engine, with a maximum afterburner of 13.5 tons, gives the J-9 formidable maneuverability! Now it seems that it has been improved again!
"It wasn't much of an improvement. The relevant departments simply upgraded the turbine materials, which only increased the thrust by 1 ton," Old Song said with a smile.

One ton, that's all?

What does this 1 ton mean?
The maximum military thrust has been increased to 9.8 tons, and the maximum afterburner thrust has been increased to 14.5 tons! So, our aircraft can probably cruise at supersonic speeds now!
"When they switch to turbofan engines later, the thrust will decrease, and the Air Force might not be able to adapt," Qin Liang remarked.

The passenger aircraft engine project is progressing smoothly, and adapting it into a fighter jet engine wouldn't be difficult. However, the planned thrust of the WS-10 turbofan engine is only in the 12.5-ton range. Will the Air Force later find the WS-10's power insufficient and refuse to replace it?

"Yes, so our WS-10 turbofan engine also needs to step up its efforts. We can't let our air force get used to the WP-15." Old Lin said with a smile, looking at the aircraft again.

At this moment, the fighter jet had completed the high angle of attack takeoff maneuver, climbed to an altitude of 500 meters, and then made a small angle turn, turning back with incredible agility!

"Great!" many people cheered.

Just such a small-radius maneuver provides a huge advantage in actual combat. When being tailed by an enemy aircraft, a single turn can shake off the opponent and then catch up with its tail!

"As expected, its maneuverability is higher than that of the Super 7 JF-17 and similar aircraft... Wait, what is the pilot doing?"

As everyone watched, the fighter jets flew over, but...

The nose of the plane continued to rise, creating a large angle, but the fuselage did not climb up; instead, it flew horizontally, and its speed was constantly decreasing!

"Slowing down and leveling off, that's impressive!"

"That's right. At this point, the aircraft and engine are close to their critical points, aren't they? The slightest carelessness could lead to a stall or engine failure. The fact that this aircraft can still maintain balance under such circumstances is a testament to its excellence!"

The acceleration of an aircraft is beyond doubt, but sometimes it is necessary to decelerate quickly. At this time, the pilot will pull up the nose, and the entire fuselage will become a huge speed brake, and the speed will drop rapidly!
However, at the same time, the plane will be very difficult to control, and may even stall and crash!

The plane in front of them slowed down more and more, until it reached them at a speed of about 200 kilometers per hour. The plane was now directly in front of them.

The next moment, the flames at the tail blazed up, the afterburner was activated again, and it accelerated its ascent!
Half somersault, dive, 360-degree flip, power spin...

"It's so good to be young!" Old Lin exclaimed, looking at the sky.

These maneuvers require either 7G or 9G of overload, and even with anti-G suits, the pilots themselves must be in excellent physical condition to perform them!

Lei Qiang has pushed the J-9 to its limits!

Below, cheers and applause resounded, and the scene was electric.

Three minutes later, the fighter jet roared down, touched down, deployed its drag chute in one smooth motion, and Lei Qiang maneuvered the jet back to the parking apron, stopping right in front of everyone.

"Excellent! Our Air Force is very satisfied with the performance of the J-9!" Elder Lin said. "Now, I announce that the J-9 has been officially finalized, and the Air Force will purchase an initial batch of fifty aircraft to provide to our seed units!"

"Thank you for the Air Force's trust. Our Factory 132 will do its utmost to complete the production task with high quality and quantity!"

"Alright, now, everyone go up and take a look!"

With a whoosh, a group of people rushed towards the fighter jet, while Old Lin walked towards Qin Liang.

"Liangzi, you got something to say, kid?"

"Old Lin, now that the J-9 fighter jet has been finalized, how about... we let it make an appearance at the military parade?"

Wait a minute, Old Lin's expression is really strange. What does that mean?
Qin Liang felt completely bewildered.

"Old Lin, this fighter jet has already completed all the test flight subjects. During the test flight phase, it must have already been detected by foreign reconnaissance satellites. Once it is equipped by the troops, it will be impossible to hide it. In that case, why not just show it off openly?"

Qin Liang assumed that the Air Force was just being stingy and keeping good things to themselves.

Old Lin's gaze... remained complex.

"Old Lin, what happened?"

"You're leaving no way out for the North."

"What do you mean?"

"The parade equipment was finalized last winter. At that time, it was confirmed that the J-8 fighter jet would participate, but... recently, people in the north have been feeling uncertain and have applied to their superiors to have the J-8 withdrawn from the parade..."

What?
Qin Liang's eyes widened: "The J-8 has already been exported, and they still have no confidence?"

There's a saying that goes, "You can't judge a book by its cover."

The J-8 has been under development for so long, it should be ready by now, but... the people at the Northern Institute still lack confidence!
Military parades are different from other events; they carry significant political importance. If one makes a fool of themselves during the parade, the consequences...

I've seen it. Those people in the north are still the same as before; everyone's afraid to take responsibility!

"Old Lin, we have confidence in the J-9 fighter jet. It will definitely not fail us at the military parade! If anything goes wrong, you can execute me!" Old Song, who had been listening to the conversation, straightened his chest.

"Alright, since you have the guts, the Air Force won't hold back either. Advanced equipment should be displayed. The Air Force has approved the J-9 fighter jets to be on display at the military parade!"

capital.

Snapped!
Old Zhang slammed his fist on the table: "Is this the strength of your Northern Institute? After so many years, you still have no confidence in the J-8! In that case, you shouldn't participate in any projects anymore. Just focus on solving the technical problems of the J-8!"

A group of people from Shenyang, their faces pale.

"Commander Zhang, we were actually willing to participate in the parade, but during close formation flying, the pilots reported that the J-8's rear fuselage would sway laterally, so..."

The J-8 was never fully understood from the beginning of its design, which led to a series of problems. Even now that it can be exported, there are still many unresolved issues!
To be inspected, aircraft must fly in close formation and form a beautiful array. After rehearsals, they discovered that the fuselages of the rear aircraft would inexplicably sway sideways. What if something went wrong during the inspection?

The planes collided and crashed, landing on top of the crowd below...

Then all those R&D personnel will probably have to eat peanuts.

"I don't want to hear about the difficulties you encountered. I only care about the results, and the result is that the J-8 fighter jet won't be in the military parade! What kind of 'eldest son of the Republic' are you? Bullshit!"

Old Zhang is angry, and the consequences will be severe!

Jingle Bell……

Just then, the phone rang.

"Hey, it's me! What? Chengdu's J-9s are going to participate in the military parade? Great, let's welcome them! Perfect timing, let's replace the J-8s!"

Snapped!
Old Zhang put down the phone and looked at the people in his office: "Did you all hear that? The J-9 is going to participate in the military parade. Your planes are fine as they are! Alright, get out! Remember my words, as long as the problem with the J-8 is not resolved, you can forget about applying for any new projects!" A group of people came out, their expressions complicated.

"The J-9 has made it, so if our J-8 can't make it, it would be really embarrassing!"

"It doesn't matter if we lose face. Who can take responsibility if something goes wrong? Even if the Air Force doesn't like us, it's fine. We have a cooperative project with Germany. In the future, the Air Force will definitely take a liking to our stealth aircraft!"

"Yes, thanks to Northwestern Polytechnical University..."

As Li Gong finished speaking, he suddenly thought of something: "Do you think we should ask Northwestern Polytechnical University for help in solving the problem of the J-8 fighter jets flying in close formation?"

"Yes, if we hand it over to Northwestern Polytechnical University, they can definitely solve the problem, but... we'll just get ripped off by them again!"

"Old Gu is still over there. Let's go over there first and see what he has to say!"

"Let's use the Beidou terminal to send the message, that way Old Gu can receive it directly!"

Northwestern Polytechnical University, Department of Materials Science and Engineering.

"Liangzi, are you saying that the infrared imaging device here can upgrade the performance of our short-range air-to-air missiles to another level?" Old Lin asked excitedly.

After the J-9's type approval ceremony concluded, the Air Force delegation visited Northwestern Polytechnical University. Qin Liang did not disappoint them, leading them straight to the Department of Materials Science and Engineering.

"That's right. This imaging device can not only clearly see the specific outline of the aircraft, but also the outline of each flare. With it, the enemy aircraft will have no chance of escaping!"

Infrared imaging devices have a wide range of applications!
Carried by a single soldier, turning night into day, equipped on tanks, it can easily hunt down opponents at night; when used with missiles, the enemy will have nowhere to hide! It can even be installed on interceptors outside the atmosphere to achieve precise target locking and then ramming into them!

This is our cutting-edge technology!

"That's fantastic! When we introduced the Python-3 technology, we were already completely obsolete, weren't we?"

"No, no, not at all. We can also export them!"

Even the export version is advanced! And the one for domestic use... well, it's even more of a killer product!

"That's right, the PL-8 and PL-9 are still very competitive on the international market." Old Lin nodded. "As for the ones we use ourselves... they're practically alien technology!"

"Thank you for the compliment. Now, let's take a look at the brand-new solid propellant..."

"Comrade Qin Liang! Comrade Qin Liang!"

"Old Gu?"

Old Gu had run over, and was covered in sweat.

Qin Liang quickly helped Old Gu sit down: "What is it?"

"I heard that our J-8 fighters are having problems with formation flying. If this isn't resolved, they won't be able to participate in the military parade. Do you... have any solutions?"

"Well..."

"If you're willing to resolve this, we'll offer... we'll offer one hundred million US dollars!"

Everyone was stunned. When did the Northern Institute become so extravagant?

"Old Gu, where did you get so much money?"

"Distinguished leaders, Comrade Qin Liang recently introduced us to a business opportunity, and we've made a fortune. We mustn't forget those who helped us..."

"Old Gu, you guys made another killing? How much?"

"Not much, just three hundred million US dollars."

What?
Countless people present were stunned.

Qin Liang smiled. This was a matter of chance. Since they had come across it, they should give it a push. Old Gu's meaning was also very clear: this business was introduced by Northwestern Polytechnical University, and they couldn't keep it all to themselves. They also had to give a portion back to Northwestern Polytechnical University.

Everyone should carry the sedan chair.

"Money is easy to talk about, let's talk about the specific issues first."

"When they fly in close formation, the rear fuselages of the last few planes will shake..."

"This isn't difficult. We'll lend you our supercomputer for a few days to simulate the aerodynamics of formation flight, and you'll be able to find the problem. The J-8 is our first domestically developed fighter jet; we can't let these minor issues delay the parade..."

The Air Force leaders opened their eyes wide once again.

The problem that had plagued the Northern Institute for so long, even to the point that its engineers had to give up participating in the military parade, was a simple matter for Northwestern Polytechnical University.

How can the difference between people be so great!
"Okay, I'll go right away!"

capital.

"Professor Gu replied; Northwestern Polytechnical University is willing to help resolve this!"

"Okay, let's take the technical data to Chang'an right now!"

"No, we need to go back first and report to Elder Zhang!"

Inside the office.

Old Zhang looked at the people walking in from outside and asked, "Why are you back again? Has the problem been solved?"

"not yet."

"Then why did you come back? My time is very precious, and I can't let you waste it like this!"

"Commander Zhang, the problem will be resolved soon. We're here to report to you that the J-8 will definitely participate in the parade on time and will absolutely not let us down!"

Now it was Old Zhang's turn to be curious.

"Have you found a solution to the problem?"

"Ah."

"any solution?"

The people who came in looked at each other, and finally, it was Engineer Li who spoke first.

"Please ask Northwestern Polytechnical University for help; they're using a supercomputer to analyze the aerodynamic problems of the formation..."

It's still Northwestern Polytechnical University!
Professor Zhang lamented, "What's the point of having your Northern Institute? Why don't you just assign any tasks to Northwestern Polytechnical University?"
"Okay, you can go now!"

After watching everyone leave, Old Zhang pondered for a moment and then called his secretary.

"Call Qin Liang from Northwestern Polytechnical University over here to brainstorm ideas for our military parade."

"Yes!"

Northwestern Polytechnical University, Department of Electronic Engineering.

"The CCD sensor was actually invented in the early 1970s by Boyle and Smith in the West. However, it's not easy to manufacture. Our Department of Electronic Engineering can only produce a 320x240 sensor in our experimental workshop at present. But we believe that with the improvement of the process, the resolution will become higher and higher..."

In later generations, film cameras no longer exist; image sensors are now CCDs! This technology is equally important in the military, for example, for aerial reconnaissance…

"Hmm, not bad, Northwestern Polytechnical University..." Just as Professor Lin was about to say a few more words of praise, someone walked in.

"Report! A message has arrived from the capital, inviting Comrade Qin Liang to come to the capital to participate in the planning of the military parade..."

What?
Me, a graduate student at Northwestern Polytechnical University, actually having to plan a military parade? Is this something I should be worrying about?
Qin Liang was speechless.

"Perfect timing! Tonight, I'll take one of our Air Force planes back!" Old Lin said with a smile. "Liangzi, the military parade is the most important event for our country right now. The fact that you can participate shows how much the higher-ups value you! You must seize this opportunity."

Qin Liang looked up at the sky: "Yes, thank you for your high regard, leader..."

You little brat, you're still not willing?

Old Lin glanced at him: "Recently, Old Zhang will be leading a team to take us on a trip. You'll be coming with us! You haven't dared to go abroad for years..."

Qin Liang sighed, "Yes, I haven't dared to go out all these years. If I can't afford to offend them, I can at least avoid them."

but……

"Mr. Lin, you should go back first. I need to prepare in a few days."

"Okay, we'll be waiting for you in the capital!"
