The military-industrial scientific research system of the academic master.

On the other side, after Lei Qiang piloted the aircraft into the taxiing stage, the engineering and technical personnel not directly involved in flight command, including Chang Haonan, were transferred to the management desk.

When No. 1001 lifted its wheels in the first half of the runway, everyone at the scene even burst into confusion.

After all, under normal circumstances, an aircraft carrying out its first flight will choose to taxi on the runway for a while to ensure safety, increase the speed to a safer level, and then choose to take off.

Moreover, the more common models of the Chinese Air Force, the J-7, Qiang-5, and J-8, are all players with very high take-off speeds. Therefore, many people who have not paid special attention to the field of aviation technology will subconsciously think that they are hundreds of times larger. A sliding distance of one thousand meters is normal.

In comparison, it is indeed too early for the J-10 to lift its wheels less than 400 meters away.

The plane hadn't even reached the front of the viewing platform yet.

In fact, Lei Qiang, who was piloting the plane, initially wanted to press the nose of the plane and pull the plane up as close to the center of the runway as possible.

One is to leave some redundancy, and the other is that the visual effect will be more shocking.

However, the design of the canard and enlarged delta wing layout is indeed too good in terms of lift (the canard aircraft relies on lifting the front wing to obtain torque when raising its head, while the conventional layout relies on pressing the tail downward, which will lose a certain amount of total lift). In addition, in order to test the working condition of the engine control system, he deliberately pushed the rod harder, causing the aircraft to accelerate much faster than expected.

In short, when the plane slid to a position just over 300 meters away, the tendency to lift off the ground was already very obvious. Pressing it down forcibly might cause certain risks, so Lei Qiang simply pulled the lever and demonstrated the excellent takeoff and landing of Project . ability.

Unlike the second-generation aircraft that only pursue high altitude and high speed, the third-generation fighter's choices in design theory will pay more attention to real maneuverability and agility at medium and low speeds.

Although take-off and landing capabilities do not directly reflect maneuverability, it is also a relatively intuitive reflection.

Especially for laymen who don’t know much about aviation or the Air Force.

During the taxiing process just now, the J-10's engine control system left a deep impression and strong confidence on Lei Qiang, so he finally chose to implement Plan B specified at the pre-flight preparation meeting.

That is, a relatively radical plan.

After confirming that the aircraft was safely off the ground, Lei Qiang did not let the aircraft continue to climb at a small angle. Instead, he quickly pushed the throttle valve and continued to pull the lever, allowing the prototype to rush straight upward at an angle of about 70°.

This is also the limit Xin Xiaowen set for him.

Although the J-10 can theoretically maintain acceleration while flying vertically upward when carrying a light load and light fuel, it is still its first flight after all, so it still has to take its time.

Of course, the so-called "take it easy" is relative to the limits of the aircraft.

Due to the angle of the viewing platform, in the eyes of the on-site audience, Plane 1001 almost performed a vertical climb immediately after takeoff.

The doubts on the viewing platform turned into exclamations, followed by warm applause.

After a short and rapid climb, aircraft No. 1001 reached the predetermined altitude of 2100 and a speed of 490.

The weather conditions at the scene were excellent. Even with an ordinary telescope, one could clearly see the posture of the two aircraft in the sky.

According to the previous test flight plan, the next step was to circle the field for two weeks.

The hovering angle in Plan B is also larger, close to 90°, and there are two rolling flights.

Although they are not dazzling maneuvers, for the audience at the scene, seeing the first third-generation aircraft completely developed by our country take off is already surrounded by a huge sense of happiness.

Chang Haonan, who had watched the J-10 first flight videos many times in his previous life, did not focus all his attention on the air. After the first lap of the field was completed and it was basically confirmed that there were no problems with the flight conditions, he communicated with the flight test station through the intercom. Understand the feedback from test pilots in real time.

And by the way, he guided the photographer sitting on coach 8 to take photos.

In fact, he even wanted to repeat the same trick at first and then take charge of photography himself.

I just thought about it and still didn’t mention it.

Chang Haonan is completely different now from a year ago.

At that time, he was just a fledgling young technician. Although he had shown some prowess, his own value did not exceed the level of a normal person. He could fly as fast as he could.

Now that he has achieved a small achievement, I am afraid that even if he proposes it, it is unlikely to be allowed.

In order to ensure adequate flight performance, the accident tolerance of tactical aircraft, including trainer aircraft, is several orders of magnitude higher than that of passenger aircraft.

"Look, it's rolling, it's rolling!"

Chang Haonan put down the walkie-talkie and heard another burst of excited sounds from around him.

He also raised the telescope in his hand again and looked at the sky.

After all, this is a test flight content that was not available in the previous life.

As an aircraft that focuses on agility, the J-10's roll rate is among the best among third-generation aircraft. Two consecutive 360° rolls are completed in a short time, and the program effect is full.

Apparently, the aircraft performed quite well.

And in the process of taking off for the first time, it has given the pilot enough confidence.

This is actually quite difficult.

Many models, even those that became very successful, did not go well during their initial test flights.

Su-27, F15, and F16 might as well be like this.

Even the J-10 in the original timeline is the same.

Although there were no major problems, there were quite a few minor issues.

However, now, the No. 1001 aircraft, which has not experienced those two damage repairs, is obviously much more perfect.

The test pilot even said on the radio that he didn't think it looked like an airplane on its first flight.

The moment he put down the telescope, Chang Haonan noticed that the senior leader in the front row took off his black-rimmed glasses and used this action to gently wipe the corners of his eyes.

At this moment, the intercom placed next to Chang Haonan rang again:

"The pilot reported that the aircraft was in very good condition, with sufficient fuel remaining, and requested a go-around and two more laps."

Xue Chishou and several other people looked at each other a few times, and they all saw the same answer on each other's faces.

"Approval of request."

Yang Wei picked up the walkie-talkie and replied.

Soon, the prototype aircraft that completed its second circle reappeared far away from the end of the runway and slowly descended.

The test flight went smoothly, and there were even people on the viewing platform who were ready to get up and go to the tarmac to greet the pilot as he disembarked.

However, the aircraft only lightly scraped the ground with its main wheels, then accelerated and climbed again, returning to the air.

After almost a full second of silence, everyone realized that this was part of the first flight.

Now, even people who don't know anything about aviation know that the plane should be in pretty good condition, otherwise it wouldn't be doing so much fun.

The cheers and applause started again.

Five minutes later, as a red and white parachute bloomed behind the aircraft, the first flight of Project 5 was finally completed successfully!

Rongfei originally arranged a shuttle bus to take people on the viewing platform to the tarmac to greet the pilots, but because the number of people present to watch far exceeded the initial expectations, many people still had no seats. .

Many spectators who were in their 40s, 50s, or even older couldn't wait to get on the next bus and followed the car directly behind them.

Fortunately, the distance between the two is not far, otherwise Chang Haonan would still be a little worried——

If the plane and the test pilot were safe and sound, but something happened to the audience, it would probably leave a mark in the history of international aviation...

When a flood of people rushed to the tarmac, the J-10, which had already thrown away its drag chute, happened to follow the guidance and park at the pre-designed parking spot.

The moment the canopy opened, cheers almost filled the sky.

Lei Qiang took off his oxygen mask and flight helmet on his own, and then waved outside.

The test flight just now was obviously not abnormal, at least it did not bring any great physical burden to him.

A young ground attendant struggled to get through the crowd holding the boarding ladder and put it on the left side of the cockpit as usual. Then he felt as if someone was tapping him on the shoulder.

"What……"

Halfway through his words, he turned around and found that what came into view was a face he had only seen on the news network in the past.

"Comrade, please go and bring another ladder. We want to take a photo with the test pilot."

"Eh... ok, ok..."

The young man who was personally instructed by the leader was a little embarrassed to speak excitedly, but he still used the shortest time to move another boarding ladder from Coach 8 not far away, leaving Li Yong who had just opened the cockpit and the front seat. The photographer stared blankly.

The second boarding ladder was quickly set up on the other side of the cockpit.

Chief engineer Xue Chishou and the top leaders took a photo with Lei Qiang, who had just stood up from the cockpit.

"Thank you, thank you for everything you have given!"

The big leader looked around, first to the test pilot, and then to everyone around him and said loudly.

According to Chang Haonan's speculation, many people at the scene should have cried with excitement.

As for why it is speculation——

Because his vision was also a little blurry.
