Chapter 791 The Flexible Fatty

That afternoon, the No. 1121 prototype conducted another long-distance taxi test.

The final maiden flight was scheduled for the next day.

The test pilot was an old acquaintance of Chang Haonan.

Fu Guoxiang.

Before boarding the plane, Chang Haonan went to the flight briefing room to chat with the other party.

Then he found out that the latter had been promoted to Air Force Colonel.

Considering his age, he has made rapid progress.

As if noticing that Chang Haonan was staring at the rank of the training uniform on the hanger next to him, Fu Guoxiang said while sorting out his flight equipment:

"I was able to get the promotion this time thanks to the many test flights I participated in in recent years. I have flown almost half of the new model prototypes and verification aircraft in the entire army."

Chang Haonan has never joined the military in his two lives, so this is an area he has never known before, so he asked curiously:

"I know that flight time is very important for pilots, but do you also have assessment standards for the number of aircraft models?"

"Of course,"

Fu Guoxiang nodded, and began to fill in the flight plan while answering:

"As for test pilots, it is very important to be selected. In fact, they are all experienced veterans. There may not be much difference between 4,000 hours and 3,000 hours, but flying one more model or one less model often makes a big difference. "

"For example, I have flown the J-8C, J-8IIACT, J-11A, J-11AM, and the F14, which only less than five people in the entire army have flown, in the past four years. It is equivalent to experiencing domestic, Soviet and American aircraft. Even in the profession of test pilots, there are very few people with such experience..."

When talking about this, Fu Guoxiang's tone was full of pride and excitement.

In fact, in terms of models alone, there are many Chinese test pilots who have flown aircraft from three countries.

It's just that the third type is mostly French models.

In the 1980s, when relations with the West were good, many pilots participated in the training provided by the French Air Force and considered purchasing French aircraft.

So, there are many people who have flown Alpha Jet, Mirage 2000 and Mirage F1.

But the F14 is a rare thing.

Or in other words, only a few Chinese pilots have ever come into contact with variable-sweep wing aircraft.

At 10 a.m., Fu Guoxiang sat in the cabin of the No. 1121 prototype and began the final inspection before takeoff.

Next to it, a specially modified J-11AS fighter was also preparing to start up with the help of a group of ground crew members.

According to the plan, this aircraft will undertake escort and optical observation tasks.

"This is a big upgrade..."

In the command center, Chang Haonan put his hands into the sleeves of his cotton coat and said while looking at the busy people and cars on the apron in the distance.

He Ming naturally knew that this sentence referred to the aircraft used for escort.

"There is no way. After all, the performance of the test aircraft models is getting better and better. The old models often cannot keep up with the requirements." He Ming replied: "Like the previous J-8C's first flight, it was accompanied by a J-6 trainer. It was slow and had poor visibility. The key is that the range was too short. Now this heavy aircraft test flight is normal for two or three hours in the sky. The old models can't keep up at all, and sometimes they have to change aircraft in the middle." "So we simply went all out and arranged to produce an extra J-11AS after the 03 batch to stay in the factory. In addition to accompanying, it can also be used to help brother units test some new equipment or something. After all, the aircraft is large enough and easy to modify." With a large number of orders from the Chinese Air Force and two big jobs from the Persian Air Force, Factory 112 is now fully worthy of being rich. Moreover, this can be regarded as a long-term investment. Although He Ming said that he was "helping" to test new equipment. But if it is actually operated, it will definitely not be in vain. Especially in the past one or two years, perhaps inspired by the success of the J-7F and several self-funded projects, many factories have begun to explore the possibility of developing some products for the international market without military orders.

And these things are obviously impossible to test with the Air Force platform.

Then, Factory 112 can make a fortune from it.

Moreover, it is guaranteed to make money regardless of drought or flood -

It's like the gold rush, gold diggers may not make money, but those who make money from gold diggers will definitely make a fortune.

"So... has anyone asked you to do a test?"

Chang Haonan asked curiously.

This question caused a silence.

"Well... not yet."

He Ming sighed at first.

But soon he cheered up again:

"But I think there will be one in the future."

While the two were chatting, Fu Guoxiang's No. 1121 aircraft had already driven along the taxiway to the take-off preparation position.

"The No. 1121 prototype has been inspected and can take off..."

"..."

Day after day, the conversations between the pilots and the tower are almost the same, so dull that it even makes people feel a little bored.

But for the staff here, they would rather be bored like this throughout their careers.

After all, if the test flight work is exciting, it is generally not a good thing...

From the perspective of the tower, Chang Haonan can see that the side of the runway is painted with equidistant horizontal lines, which should be used to intuitively see the take-off or landing distance of the aircraft.

The row of people standing in front of the window almost all stared at the rear wheels of the No. 1121 aircraft.

Just after the sixth line, the plane took off lightly.

"Good!"

He Ming held the telescope in one hand and waved his fist in the air with the other hand.

"Is this line 50 meters?"

Chang Haonan probably had a guess.

The structural weight of the new body is originally low, and the original N001 radar with a shocking size has been replaced, so the actual empty weight of the J-11B that came off the line is 800kg lighter than the old model.

Even for a twin-engine heavy fighter, this is not a negligible number.

Therefore, the take-off distance will definitely be improved compared to the J-11WS verification aircraft that has only changed engines.

"That's right."

He Ming nodded.

At this time, the No. 1121 aircraft that had taken off the ground had begun to climb almost vertically.

Of course, the vertical climb itself can be completed even by the old Su-27SK.

However.

The process of this aircraft from nearly horizontal to vertical nose upward is extremely rapid.

It even gave Chang Haonan a feeling of watching the first flight of the J-10 at that time.

You know, the latter is a canard-type aircraft with an innate nose-up moment.

And the conventional structure of the J-11, in essence, needs to be like a seesaw to achieve nose-up, so that the negative lift pushes the horizontal tail downward.

Considering the problem of total lift, this efficiency is generally designed to be more conservative.

The larger the aircraft, the more obvious this situation will be.

This is why heavy fighters like F15, Su-27, and F14, which have a stronger thrust-to-weight ratio, still feel a bit bulky.

Because maneuverability and agility are originally two levels of performance.

After using the new body, agility, the original biggest shortcoming, has obviously been strengthened to a certain extent.

Even Fu Guoxiang in the cockpit was surprised by the exaggerated speed of raising his head just now.

"Interesting..."

He stared at the altimeter in front of him until the number on it showed 02500, and then he leveled the plane.

About 20 seconds later, the J-11AS responsible for the accompanying flight also climbed to the same position.

"Prepare to perform the test flight subjects."

Fu Guoxiang reported on the radio.

According to the test flight plan, the first to be carried out are more than a dozen conventional projects, mainly testing the basic flight capabilities of the aircraft.

However, thanks to the ultra-long range of the J-11, it is not necessary to return immediately after this process.

Instead, other subjects can be continued.

Of course, it was the first flight after the major structural changes, so it was impossible to directly use a particularly high intensity.

But there was one item that Fu Guoxiang was very interested in.

Half an hour later, Fu Guoxiang, who had completed a round of circular flight, re-flew the plane and returned to the airspace above Beiling Airport.

He completely leveled the plane, then slightly pushed the throttle valve, gradually accumulating the speed to a high subsonic state of 950km/h.

On the oldest model of Su-27SK, due to structural strength issues, the flight performance of the entire transonic section will be limited to a lower level by the flight control.

The J-11AM modified the flight control to accurately limit the speed section that produces restrictions to two 50km ranges.

However, because the hardware has not changed much, there are still defects.

But the second-stage upgraded fuselage used by the J-11B/Su-27SM plans to completely eliminate this hidden danger from the hardware.

After confirming that the speed reached the test standard, Fu Guoxiang suddenly pulled the stick to the right-

The familiar feeling of dizziness came.

The plane began to roll.

As a test pilot, Fu Guoxiang can still stay absolutely awake even in this environment.

"7.6 seconds."

After three consecutive rolls, Fu Guoxiang looked at the timer.

7.6 seconds, three circles, 1080°.

A roll rate of almost 140°/s.

It's obvious.

Upgrade, it works!
