The cold wind blew the northern land, the withered branches swayed in the wind, and the branches of the swaying branches had already risen a trace of green.

Winter is over, will spring be far away?

At the airport, people were still wearing military coats, and they were busy around a warplane.

If you look at it from the outside, this plane is too old and backward, it is still nose intake, wings on both sides with wing knives, the entire fuselage is not painted, revealing the kind of silver-white aluminum alloy, shining in the sun, above the fuselage, the front and rear cockpits, occupy a lot of space.

"Today, it is the first flight of our plane, and I hope everything goes well." Lao Zhou stood next to the plane and said with some concern.

The last time the first flight of the J-7, there was such a big mess, which made Lao Zhou feel uneasy, and now, it was finally their turn to make the first flight of their fighters.

The silver-white nose of this plane is painted with the number of 008, in the test flight yard, this aircraft is not called 008, and now, after hearing Lao Zhou's words, Gu Tingting said on the side: "We have been completely tested, and there will be no big problems, besides, this is not a newly developed aircraft, once there is any accident, it can be taken over by mechanical control." ”

The danger of the J-7 is very great, it is newly developed, and its own side was originally changed with a training aircraft, and it will be switched back to mechanical operation at any time, what else can go wrong with this? Gu Tingting is very relieved about it.

"Then you say, does it have any shortcomings?" Lao Zhou asked.

Gu Tingting frowned and said, "I don't like its current color, we should paint it, preferably with red stripes." This is the most eye-catching. ”

In the past, the fighter plane was not painted without any painting, and it was directly the skin of aluminum alloy, which became a silver war eagle in the sky, but with the development of the times and the progress of technology, the fighter also began to be painted.

For combat aircraft, it is very important not to be detected by the other side in the sky, which includes low visual visibility, and generally speaking, the fighter aircraft are sprayed with light gray paint, which looks mixed with the sky and is not easy to be detected from a distance.

Of course, painting can also make the surface of the aircraft smoother and reduce air resistance, so it seems that there are more elements of pulling, but in fact, before entering the jet era, many high-speed aircraft have begun to pursue a smoother surface.

The coating of the radome is generally different from the fuselage, on the one hand, it is for the discrimination of ground support, after all, the radome is not a metal material, the strength is not high, and it is easy to be damaged on the ground. On the other hand, it is also because from the nose of the machine, this color can better hide itself.

As for the kind of aircraft that wants to fly shows, of course, the more fancy the better, this 008 is a test aircraft, in order to be able to better track him from the ground, it should be painted brightly, and it can be seen from afar.

Now, Gu Tingting said this request, and Lao Zhou nodded: "Yes, let's change the livery, after this flight, we will paint it with bright red stripes, just like the previous J-6 flight demonstration team." ”

While speaking, the plane was ready to take off, and everyone dispersed, listening to the howling of the plane's turbines, and then, the J-6 slid on the runway and flew into the blue sky.

Although the aerodynamic shape of the J-6 is very backward and the maximum speed is not high, however, this aircraft has a unique advantage, it uses two engines, strong power, and the thrust-to-weight ratio is close to 1, so when taking off and running, accelerating and climbing, it is quite powerful.

Now, this is the case, even if it becomes a test aircraft, in the test flight yard, the take-off of this aircraft is quite rapid.

In particular, it is also equipped with fly-by-wire control, even if it is only in the vertical direction, when Tang Gang in the front seat pulls up the operating lever, the nose of the machine will be raised, and the reaction speed is much faster than that of hydraulic operation!

The first flight of this plane was handed over to Tang Gang, who was in front, operating the fly-by-wire system, and behind him, his comrades-in-arms who followed him in the test flight, and the two piloted the plane together.

The stabilizer flew into the sky!

Tang Gang shouted on the radio: "008 report, everything is normal, the control is very flexible!" ”

This is the first test flight, according to the test flight procedure, is to go around the airport, just when he climbed and was about to turn, a voice came from the earphone: "001 call the test flight institute, 001 call the test flight institute, request to arrange landing." ”

001？ Although this number has changed, the voice will not change, when he heard this voice, Tang Gang immediately became excited, it was Brother Feng, it was Brother Feng who came over!

This big brother taught him to test fly hand in hand, the two are half-teachers and half-friends, and now, hearing Qin Feng's voice, Tang Gang is quite happy.

Radio calls, watching movies, seem to be omnipotent, in fact, there are great limitations, not to mention the problem of encryption, just talking about the frequency band of this call, is a very important issue.

Generally speaking, a squadron uses the same frequency band, so that when one person speaks, the whole squadron can hear it, so there must be a complete set of rules, otherwise, if everyone is talking inside, it will be so noisy that no one can hear clearly.

The base of the test flight institute is also like this, there is only one commonly used communication channel, fortunately, there are not many fighters flying at the same time, so it generally does not cause interference, and when one of them calls, the others can also hear it.

Although the knob can be adjusted to change the frequency of communication, but the two sides of the call must switch the frequency at the same time, and when the Western pilot wants to whisper in the movie, he is in the cockpit with his companion to turn the radio to a certain frequency.

Now, Qin Feng's fighter plane happened to fly over!

Tang Gang looked in the direction of the north, and soon, he saw a shadow, which was slowly getting bigger and bigger, and finally he could recognize it, this was a two-seater fighter-bomber!

"008 is in stable condition, please fly one more lap, get out of the runway, and let 001 land first." Tang Gang shouted over the radio.

The runway of the airport is limited, so if there are more planes, then you also need to queue up for landing, for example, the general civil aviation airport is like this, while requesting landing, while going around the airport in circles, waiting for the following arrangement.

Tang Gang flew the stabilization plane, it was supposed that he should have landed, but since there were guests from afar, of course the guests had to land first!
