Chapter 296: Unfair? Ha Gong Da Does Not Support Junk!

Looking at the shocked crowd, Song Lao continued: "Next, I will introduce the second important indicator, the maximum controllable angle of attack, which also reflects the standard for nose-pointing capability. Our design can fly at an angle of attack of 36 degrees."

Instant turn is the ability to point the nose horizontally at a target, but enemy aircraft may not be at the same altitude, meaning there is also a demand in the vertical direction.

If it's lower than us, it doesn't matter—we can just dive down; but what if it's higher?

At that point, we have to pull the nose up and go toward them!

This performance is equally important for fighter jets. However, due to technical limitations, earlier fighters had low values for this indicator—for example, the domestically produced J-7, a copy of the MiG-21, has a maximum angle of attack of only fifteen degrees; pilots can certainly pull higher, but the result is the wings lose lift and the jet plummets from the sky.

Only with third-generation aircraft did they start emphasizing high angle-of-attack performance; with the F-16, the limit was raised to 27 degrees, which is already very strong!

Of course, with engine power, even if the angle of attack is pulled to ninety degrees, the F-16 can still climb vertically effortlessly, and the Su-27 can even reach 110 degrees during a cobra maneuver, but these are in normal flight, and the control moment of the control surfaces also drops sharply.

Even if the engine is a burden, our J-10 can still fly at an angle of attack above thirty-five degrees, and this is fully controllable!

Of course, American fighters also have astonishing capabilities—for example, the F-18, with its large leading-edge extensions, can exceed fifty degrees angle of attack, but that came later.

Now, the 611 Institute's project, based solely on these two data points, is enough to look down on all rivals!

As for the other data… some are indeed lacking, such as stability, climb rate, acceleration—anything that relies on engine power will be weak, but this isn't unsolvable; later, when domestic technology advances and we have advanced high-thrust engines, these performances will naturally improve, and then we'll be even stronger!

"Hmph, bragging!"

Hearing that sarcastic tone, Qin Miao couldn't stand it.

"Just because you can't do it doesn't mean others can't! Saying such things only proves your own ignorance!"

In the 601 Institute, the person who had just spoken immediately lowered his head; if someone else had said it, he might still talk back, but Qin Miao had just promised to help them modify the nose, and they all knew how great the benefits would be—offending Qin Miao now would mean even their J-8s would likely be defective, with not a single combat-worthy model left.

Song Lao glanced gratefully at Qin Miao, then turned to all the leaders present: "Ladies and gentlemen, these numbers we've mentioned come from tens of thousands of wind tunnel tests and tens of thousands of calculations on draft paper! I, Old Song, can guarantee here that if the developed aircraft fails to meet these performance indicators, I will accept execution by firing squad!"

After saying that, he looked toward the 601 Institute and said: "Those who think I can't do it, shall we make a bet? If I fail, I'll eat peanuts; if I succeed, you just need to apologize here."

It was dead silent there.

"Cough, cough." Gu Lao said: "Old Song, don't be so heated; these numbers are indeed shocking to us—we just find them hard to believe. If you really can achieve them, I, Old Gu, will host a celebration banquet for you… but… even if you use adjustable canards, I doubt you'd have such good maneuverability."

"Yes, to improve maneuverability, we decided to use an unstable configuration……"

The crowd was shocked again.

Weight is distributed throughout the aircraft, equivalent to a single point—the center of gravity; at the same time, for flight, lift must be generated, and the total lift acts at a single point—the lift center, or aerodynamic center.

When the two coincide, or when the aerodynamic center lies behind the center of gravity, the layout is statically stable.

Simply put, when the aircraft pitches up, its weight pushes it nose down, and vice versa; in short, the aircraft has a tendency to restore balance on its own.

And static instability is the opposite: when the aircraft pitches up, the center of gravity presses on the other side of the seesaw, also pushing it up; in this case, the aircraft cannot correct its attitude by itself, so the control surfaces must be constantly adjusted.

Humans lack this ability; only a computer can control it! Therefore, a statically unstable layout must be flown via fly‑by‑wire! And we designed it this way, of course, to make the aircraft more agile!

Moreover, the canard layout's control law is inherently nonlinear, so it must use fly‑by‑wire, and in fact it naturally goes hand‑in‑hand with static instability!

What is a third‑generation aircraft?

To harness vortex lift and relax static stability, such an aircraft achieves the strongest maneuverability!

"Old Song, your technological leap is too great, I'm afraid……"

The difficulty of writing the flight control software is hell‑level! Their J‑13s are planning to copy the F‑16 outright, not daring to change a thing, while the 611 Institute over here actually wants to radically modify it!

That's absolutely impossible!

"If we don't take big steps forward, we'll forever be trailing behind others!" Song Lao said: "But we're not fighting alone; in this area, we hope to get Ha Gong Da's cooperation."

The Mirage 2000 and Furious Wind also use fly‑by‑wire, and together with the F‑16 we have three different models for reference; plus the 611 Institute's years of hard work, how could we still fail to sort out the flight control?

This hurdle must be overcome! Otherwise, we'll forever be trailing behind others!

"Good, Ha Gong Da will give full support!"

"Comrade Qin Miao, this is unfair! You ignore our 601's flight control, yet over at 611……"

Unfair, unfair!

Qin Miao smiled: "If your design specifications match those of 611, then Ha Gong Da will also fully support your project!"

Some harsh words are hard to say, but Ha Gong Da does not support junk!

Lin Lao beside them also smiled and nodded: "A piece of junk, is it even worthy of Ha Gong Da's attention?"

"Thank you, Comrade Qin Miao." Song Lao felt deeply moved; with Ha Gong Da's support, this project is now even more problem‑free!

"Ladies and gentlemen, next I will introduce some specific aircraft designs……"

Afterward, the meeting room became Song Lao's solo stage; he spoke for over two hours, and everyone except the 601 Institute listened attentively.

After Song Lao stepped down, the situation was clear: the 611 Institute's project completely overwhelmed the 601 Institute's project!

The only problem is……

"The 611 Institute's project is very radical; if successfully developed, it will completely solve the Air Force's equipment shortage, but the risks are also significant. San Shui, you say, with Ha Gong Da's cooperation, can we complete this project's development?"

Qin Miao understood that Lin Lao meant for him to nod, to give everyone confidence, but Qin Miao…… firmly shook his head.

"No."

"Why?"

The whole audience was stunned; after all that talk, who exactly are you supporting?
