After sliding on the runway for hundreds of meters, Long Yun slowly taxied the fighter to the other side of the runway, waiting for the battery car to come and tow the fighter back to the hangar.

Although the ground test car just now was only a small test, the maximum speed of the fighter exceeded 150 kilometers per hour; When refueling and speeding up, Long Yun could feel an obvious feeling of pushing back. Sure enough, it's more enjoyable to fiddle with the airplane, and it's more energetic than a sports car with a little oil!

After the completion of Long Yun's test process, it was Liu Wei who drove another J-7 for test drive and ground coasting. Long Yun didn't fully understand his technique, but there was no danger in testing it on the ground; Unlike Long Yun, who has been fighting many times, Liu Wei is still quite unfamiliar with fighter planes, which just makes him more familiar with what it is like to drive a real fighter plane.

After a morning of test running, it was quite smooth, and the state of the engine and control system was verified. In the afternoon of the same day, Long Yun conducted another simulated take-off and landing training, piloting two J-7s in turn to simulate the take-off process, with the aim of ensuring that the overall state of the aircraft could meet the requirements of take-off and landing.

During this test, Long Yun also deliberately tested the afterburner action of the engine; The reason why the afterburner system was tested was because of the thrust-to-weight ratio and lift problems of the fighter. When the J-7IIM only uses the maximum thrust, the acceleration time to take-off and the running distance from the ground will be very long, so it generally needs to be turned on afterburner during takeoff.

As soon as the debugging is completed, now we are waiting for the first flight of the next day.

When he returned home that night, Long Yun, who had been tired for a day, was still a little excited, and he told Su Xue about the situation of the team, which aroused the great interest of this little girl.

"Really? Can you fly tomorrow? ”

While cleaning up the dishes and chopsticks, Su Xue felt that this should be regarded as a major event for Long Yun's team, and she was very happy for him in her heart. "Then don't forget to record and take pictures. - Oh! Also, can I go and see it tomorrow too? ”

"Good! Are you free tomorrow? ”

Of course, Long Yun is very welcome, and in a place like the training center, there shouldn't be a lot of entertainment reporters and fan groups! Recently, because of those rumors, he felt that Su Xue didn't seem to be very energetic, and it was good to take her to see the scenery and relax.

On the morning of the next day, driving the half-fueled J-7IIM, Long Yun relied on his own power to taxi to the end of the runway, and flew into the sky for the first time under the watchful eyes of Liu Wei, Su Xue and others.

In reality, this first lift-off flight, although this feeling has been experienced many times, but really holding the joystick and flying a fighter plane in the sky outside Beijing, this feeling of high sky and clouds still makes Long Yun feel quite comfortable.

In the clear blue sky, the field of vision is so wide, and the horizon in the distance looks so flat; The J-7 inherited from the MiG-21 did not adopt the Soviet Union's improvement ideas for the MiG-21, and the air intake has always maintained a finely slashed line shape, which is somewhat helpful to the pilot's downward view in front of him, which is what Long Yun prefers.

Of course, there are pros and cons in everything, limited by the size of the central shock cone, the J-7 full range of radar installation has been a headache, the current J-7II only has a simple 226A range-finding radar, the theoretical discovery distance of 15 kilometers, in broad daylight may not be as good as Long Yun's super eyesight to see far.

Perhaps, in the future, you can build a "Starlight" and buy a small pulse Doppler radar to replace it?

Long Yun thought like this, and shook his head with a smile: Since it is a chartered plane, it is estimated that except for a poor team like them, there will be no team to rent the old "Seventh Master" as a competition machine!

So who will use the radar when it is installed, that is, just think about it.

Piloting the J-7IIM, which had just been commissioned, Long Yun first carried out a basic circular level flight, trying to find the familiar feeling of driving a fighter plane. The flight altitude is kept at 4,000 meters, which is a relatively safe altitude, and even if there is an accident such as a stop in the air, he has enough time to deal with it.

Generally speaking, flying a single-seat fighter for the first time is a big test for the pilot; Long Yun, who had only flown a business jet in this world before, did not have the trust to bear the safety of the crew and passengers, but he was also more lonely to face the challenges of the entire flight platform, which made him still a little uncomfortable.

Therefore, in this first test flight, he cautiously piloted the fighter as an ordinary business aircraft, intending to find out the actual flight characteristics of the J-7, and then consider the issue of technical training.

After flying a few laps, he regained the feeling of manipulation, and Long Yun knew that Su Xue and the others on the ground were watching his flight with binoculars, and it would indeed be too dull to go around in circles like this. But until the temper of the fighter is understood, it is very dangerous to rashly carry out violent maneuvers; Long Yun considered the action combination, chose a few low-difficulty but more interesting connections, and then turned sideways and began to enter the maneuvering flight.

On the ground, looking at the fighter plane in the sky with a telescope, Liu Wei looked quite excited, after all, this was the first flight of the "Chenlong" team that he personally participated in; On the other hand, Su Xue was dignified as usual, seeing that Long Yun had been going around in circles in the sky unhurriedly, just like the illusion that most people would have when they looked at the plane, she also felt that the fighter plane was flying a little slowly.

Of course, Su Xue didn't realize that this was because of the lack of visible motion references in the background of the sky; In fact, at this time, the J-7II in the sky was already moving at a speed of about 600 kilometers per hour, which was faster than any vehicle on the ground, including the maglev train.

However, at this moment, Long Yun began to turn on the afterburner to accelerate, and at the same time entered the horizontal figure-eight flight, after completing the two cross-figures, followed by a large slope climb and reverse sharp turn to flatten, this rather thrilling action not only made Liu Wei applaud, but also surprised some people on the ground who saw it.

Of course, most of these amazing people were because they saw the figure of the "Seventh Master", not because they were admiring Long Yun's flying maneuvers, because the action he had just completed was not very difficult. If it is followed by a 180-degree roll and a reverse somersault after a large slope, it is really a difficult maneuver; It's a pity that this is impossible to complete the aerodynamic design of the J-7, and Long Yun naturally won't try it.

If it is done with a model such as the J-10, the continuous action just now can be said to be quite easy, and the overload value is not high; But everyone can clearly see that Long Yun is driving an old second-generation fighter, which is relatively rare.

At this time, Su Xue, who was watching intently, didn't understand a lot, but felt that Long Yun had finally made a beautiful move, so he applauded, and his happy expression was overflowing. Liu Wei on the side saw her so happy, and he also took the initiative to talk:

"Sister-in-law, this is nothing! Brother Long's skills are much higher than this move, hehe! ”

"-ah,-really?" was called like this by Liu Wei, Su Xue was obviously a little confused, but she didn't say anything to correct it; Raising her head and continuing to look at the figure in the sky, the girl's delicate mind couldn't help but think of the scene when Long Yun looked up at the sky at the Qingdao high-speed rail station.

Time flies so fast; This man who longs for the sky, has he finally opened the wings of his dreams......

Seeing Long Yun, who had completed the maneuver and changed back to level flight, flew low through the field, drawing a graceful arc in mid-air and entering the runway to land, Liu Wei and the others all breathed a sigh of relief.

The first flight is smooth!

This is certainly a good sign for the Chenlong team.
