At the moment when the flaps are lowered, it is only one or two breaths of time, and the front and rear wheels leave the ground one after another, although there is no fighter that can take off at a large angle by relying on a high thrust-to-weight ratio, but when the altitude is slowly climbed, the unique ability of large aircraft to block the sun and project a huge shadow on the runway is still quite visually impactful.

As the plane roared over the end of the runway, the flat mud was also blown up and dusted, and such a large-scale dust and wind and sand could be seen on this Yunnan-Guizhou Plateau, even the deputy chief engineer Nie from Chang'an had to say: "It's really hard, this scene is nostalgic!" ”

Some of the staff who also came from the west also agreed, but the theme still revolved around the first plane this time, and then they saw the two Jianjiao 7A that followed by the low-altitude passage from behind, which passed above the bushes near the airport runway, which caused a burst of cheers from the crowd of spectators, especially some residents from the surrounding Guiyang City, it must be the first time to see such a big scene, after all, this kind of dual-plane low-altitude passage is still a flight project that is difficult to see in ordinary times.

If it weren't for the importance of this first flight, which required the accompaniment of an accompanying aircraft, such a high-risk project would generally only be seen at air shows and combat units, and the unit in charge of aircraft manufacturing would generally not have a two-plane formation on the side.

"These two companion planes are really funny, if you scare the engineer on the plane, I'm going to kick the pilot's ass when the time comes, it's just a mess!"

It's quite bluffing, but the smile on his face can't be hidden, and now Yang Hui can still remember that he took the Jianjiao Seven Air Refueling Trainer to fly west, which is really exciting enough, and it is a past worth recalling for a lifetime.

And now, with the change of identity, if it weren't for the need, there would be few opportunities to ride the fighter wave again.

The situation in the sky, naturally it is a different situation, when the first plane of 01 completed takeoff, two Jianjiao 7A followed, one of which flew to the first plane of 01 a few meters higher, after the pilot deflected the angle of the left and right flaps, it was obvious that the plane had a slight horizontal angle change.

Of course, the field of vision of the engineer in the front seat is more broad, and the place that enters the air police 100 first aircraft is the huge mushroom plate, although the mushroom disk in the test is patched with a distributed air pressure sensing test system, but in order to be able to better see the air flow field near the radome during the specific flight, it is still necessary to have the relevant aircraft aerodynamic designers to observe it in person, only in this way can people rest assured.

After taking the telescope and looking at it carefully, I feel that there will be no big problems with the aerodynamic and structural design of the radome, and the bracket under the radome is also very stable.

After feeling very satisfied, I put down the binoculars at this time, picked up the old-fashioned double-mirror seagull camera that I had borrowed from the unit's propaganda office, and took a few photos with a click, and then I was satisfied with the camera with a very old atmosphere and showed a rare smile.

"Generally speaking, no problem, let's get a safe distance!"

Before he finished speaking, he suddenly encountered a defenseless air turbulence, and a small aircraft like Jianjiao-7 was very susceptible to the influence of the airflow environment, although the pilot was a professional test pilot stationed at the test flight station, but the plane still dangled in the air a few times.

With superb technology, the plane was still firmly controlled, and the frightened companion plane immediately pulled out a suitable distance from a distance, and then said that it planned to find a good observation angle, but at this time, the on-board radio heard the voice of the radio communicator of the No. 01 first aircraft group.

"Accompany the flight, accompany the flight, this is the first plane of No. 01, the tail of our plane in turbulent flight has a high-frequency tremor, flight control is difficult, flight control is difficult!"

This information naturally came out through the scheduled radio channel, and after hearing the news, the four people sitting in the two companion planes were all entangled, usually such an accident is a bit dangerous, and the professional test pilot, of course, knew what this meant, and almost did not hesitate to steer the plane and lean under the tail of No. 01.

In the past, this position was a typical position for the refueling of the bombing six air tankers, and now it is very suitable to observe the tail tremor of the No. 01, when the aircraft is adjusted in place, the afterglow looks at the other side, and it is also another companion aircraft occupying the air refueling point on the other side.

The aerodynamic engineer on the plane naturally picked up the telescope and carefully observed the situation, but at this time, he actually couldn't see any problems, but if he was so far away, the tail shaking could be clearly seen with the naked eye, and the plane would have disintegrated in the air.

Thinking carefully about the news from Unit 01 just now, this situation seems to be quite familiar, as if I have heard it somewhere, it should be

That's right, Air Police No. 1! That's right, it was the same situation at that time, and it was also the case with the Air Police No. 1 back then!

According to the current situation, it should be that the two small composite vertical tails added to the tail are not enough, and once the aircraft flies into the high-altitude turbulence, it is difficult to control, and even flutter, it seems that the aircraft needs to continue to strengthen in this regard.

"I think I can roughly understand why, if you can control the flight, please continue to fly until you have flown out of the turbulence area! Repeat, if you can"

After the crew of No. 01 came with a positive answer, the flight test continued, and the captain was actually able to roughly assess the flight situation of the aircraft, first of all, the plane was obviously still under control, and the problems encountered this time should only appear when there was turbulence in the air, as long as it could fly out of the turbulence area, it would probably be safe.

The No. 01 AWACS aircraft also does not plan to use fly-by-wire flight control and other tall equipment, and it is normal to use the traditional mechanical flight control design, so in this case, it takes a lot of effort to ensure the direction of flight, and the strength here simply refers to physical work, and it can only be stabilized after flying out.

As expected, after half a minute, the plane finally rushed out of the turbulence area in the air, and the captain could clearly feel the torque fed back by the control stick to return to normal levels, and the radio communicator, who had been terrified at the tail of the plane, also found that the annoying tremor suddenly disappeared, and he was also very impressed by the engineer on the plane next to him.
