Fu Guoxiang subconsciously held his breath.

This is a speed that the old J-8 did not dare to think of at all, and he only tried it in the past when he was flying stall performance.

However, for the current aircraft, since the test flight station allows him to try it on the first test flight, it shows that this speed is still relatively conservative.

"Roger."

Soon, everyone present – including the two Sukhoi engineers watching from a distance – witnessed the 04 verifier making a low-altitude pass with an angle of attack at an extremely low speed.

After the roar of the engine faded away again, the voices that had just been masked instantly boiled again.

"How do I feel about that speed...... You may not even be able to reach 350? ”

“350？”

Maybe it's because the sound of the engine just now is too deafening, and the voices of the people who haven't recovered have subconsciously increased a lot:

"How can there be 350, this is definitely not even 300, and it flies steadily, there is no feeling of struggle at all!"

"It's not just the speed, have you just noticed the attitude of the plane, and it has maintained a controllable angle of attack of about 15 degrees at least during the passage of the field."

Everyone is an engineer of 601, and they have a lot of virtue for the handling of the J-8 at low speeds in the past.

At 300km/h, it is theoretically possible to fly, but the plane in that state will be visibly crumbling and dangerous.

How could there be that calm and unhurried look just now?

"This performance ...... It's a bit outrageous. ”

"Don't worry, this is not the real first flight after all, there should be other test flight projects, and after the test flight is over, see how much the comprehensive performance can be improved!"

For fixed-wing aircraft, it is certainly a challenge to fly fast, but if you really want to fly slower, it is not much more difficult.

It is even more difficult to maintain effective maneuvering of the aircraft at extreme speeds such as fast or very slow, and even to ensure a certain degree of maneuverability to cope with air combat.

Especially for a second-generation fighter, it is a matter of trade-offs.

In order to make the aircraft have both high-speed and low-speed performance, countries such as the United States and the Soviet Union have chosen an extremely complex variable swept wing structure at a specific time, at the cost of huge dead weight and reliability in exchange for a certain degree of both.

It was not until the third-generation fighters represented by the F15 and Su-27 that a more acceptable balance was found.

J-8-3 as a second-generation change, although the foundation determines that there is no way to fully achieve the level of the third-generation aircraft, but judging from today's performance, the comprehensive flight performance is a 2.75 generation aircraft is definitely not a problem.

Yang Fenghat, who was standing in front of the window, didn't speak, just patted Chang Haonan's shoulder and shook the latter's body heavily.

It's all in plain sight.

Compared with Yang Fenghat, who was pleasantly surprised simply because of the performance of this aircraft, Chang Haonan, who was reborn, had a completely different feeling in the face of this J-8 low-altitude scene.

The low-altitude and low-speed performance of the J-8 is an insurmountable knot for any Chinese aviation person and even any Chinese military fan on the original timeline.

The crash in 2001 left too many regrets that can never be made up.

"Now, our plane shouldn't have that kind of defect anymore......" Chang Haonan looked at the horizon outside the window, and the corners of his eyes were slightly moist.

At this time, Yao Mengna, who was standing on the other side, had just turned around.

……

As Chang Haonan said to Du Yishan and Liu Zhenxiang at Beijing Airlines yesterday, with his help, the progress of the test flight process can be greatly accelerated.

This is also one of the reasons why Yang Fenghata dared to directly arrange complex subjects for Fu Guoxiang in this test flight.

In short, the first flight, which was not the first flight, lasted nearly an hour before ending with a puff of green smoke rising from the rear wheels of the No. 04 prototype when it touched the runway.

"Let's go, go to the tarmac!"

Naturally, the flight test data is collected and processed by the personnel of the flight test station.

The most important thing at the moment is to welcome the test pilots in triumph.

Ten minutes later, the prototype 04 slowly stopped in the designated area of the tarmac.

Fu Guoxiang turned off the engine, waited for the cockpit canopy to open, and then waited for the ground crew to move the boarding ladder over.

In the process, he had already seen a surging crowd from afar.

Although it was not the first time that most of the members involved in the 83 Project had experienced such a thing as the first flight of an airplane, everyone was still extremely excited in the face of Fu Guoxiang, who had just climbed out of the cockpit.

On the one hand, the performance of this improved aircraft is really good, which is somewhat unexpected.

A lot of people couldn't believe the data that came out of the wind tunnel last night.

But after the test flight, although the detailed data has not yet been sorted out, at least in terms of stall speed and take-off distance, it is simply better than the wind tunnel results.

This is a rare occurrence.

On the other hand, the speed with which the improvements were completed was a bit too fast for everyone involved.

From proposing improvement ideas to determining the plan to manufacturing, final assembly and first flight.

That's just over a month in total.

And this is not a small change, including a new wing designed by Chang Haonan, a cockpit canopy designed by Yao Mengna, and a series of upgrades in avionics and cockpit man-machine efficacy.

What is the concept?

In the past, this level of improvement was basically impossible to complete in a year.

So even though each process has been checked and confirmed many times, everyone is ......

I feel a little bottomless.

A bouquet of flowers was delivered to Fu Guoxiang's hands.

Because this is not a new model after all, there is no leader on the scene, the chief designer Yang Fenghata and Chang Haonan, who led the improvement, were in the center of the crowd and hugged him respectively.

"How does the plane feel?"

Yang Bonghata asked.

In the case of test flights, data is only one aspect.

The pilot's subjective feelings are actually very important.

And Fu Guoxiang's first words shocked everyone around him.

"Stronger than the Mirage 2000, much stronger!"

You must know that Fu Guoxiang once went to France for training and exchanges, and he really flew the Mirage 2000.

He said this quite convincingly.

Of course, the Mirage 2000 is, in the final analysis, a quasi-third-generation fighter based on the second-generation fighter and redesigned and manufactured according to the standards of the third-generation fighter.

But compared with typical second-generation aircraft such as the F4 or MiG-21, there is still a world of difference.

You know, about ten years ago, the Huaxia Air Force even considered the introduction of the Mirage 2000B/C type.

And now, our new aircraft have surpassed even in areas that we are relatively ungood at.

Considering that the newest fighter of the French, the Rafale, was not officially in service at this time......

The same thought appeared in the minds of many people present:

The fighters of the Huaxia Air Force may soon cease to be the weakest of the P5.

Plus more as usual in the afternoon
