Chapter 671: A Hint of Excitement
When he was alone, Qin Feng was fearless, now, with a family and children, he had more worries, in the past, he was a test flight by himself, if he encountered danger, he had to find a way to solve the problem and come back safely, but this time it was different, this time he took the initiative to find danger, dense formation, when he gradually approached, fear suddenly appeared in his heart, that was a normal psychological reaction, as long as he crossed the pole of fear, it was okay, when he flew to the future, not only would he not be afraid, There will even be an inexplicable excitement.
Now Qin Feng is overcoming his fears, he operates the fighter, slowly, slowly approaching, although he tries to control himself not to think about his family, but the face of the little tiger head still appears, and the fiery fighter wake has become the phantom of the little tiger head again.
Qin Feng didn't flinch.
I have to overcome this fear, the little tiger head is also looking at himself, this time, he must not be a turtle with a shrunken head!
The distance was still slowly getting shorter, shorter, when it exceeded ten meters, Qin Feng tried to stabilize his mind, and then continued to get closer, closer, nine meters, eight meters, until it changed to five meters, the plane in front of him was already clear.
Qin Feng can clearly see every detail of the Jian-8 fighter, especially the exposed rivets, showing a unique roughness, and the exposed rivets seem to be the mark of a man.
However, this thing will increase air resistance, so the Jian-10 fighter planned by Song Lao is to use countersunk rivets, and after riveting, it is the same height as the skin, which can minimize air resistance.
Time passed little by little, and when a minute passed, Qin Feng withdrew.
"001, 002, please follow the current route, continue to fly twenty kilometers, meet with the air tanker, at a distance of fifty meters, at a height of five meters, and pay attention to the situation."
"001 Roger." At this time, Qin Feng's tone did not show any emotional color, but his heart was extremely proud and proud, he finally overcame his fear, and he could finally continue to fly, if this fear had always existed, then he would not even be able to carry out any flight in the future, so he could only retreat.
Now he is not only without fear, but even has a trace of excitement. It's like a person who has studied for a long time, fallen a lot, and finally learned to roller skate. If it weren't for the oxygen mask, Qin Feng would have the urge to whistle.
It is not difficult to maintain a distance of fifty meters from the tanker at all, and compared with the formation practice of the two people just now, because the volume of the tanker is larger, the turbulence at its tail is stronger.
Now, looking out through the narrow cockpit of the J-8 fighter, you can already see the bright spots twenty kilometers away, the air tanker, waiting there!
This kind of training is not only a test for the tanker, but also a test for the air tanker, at this time, in the air tanker, the captain and the pilot, are in front, controlling the plane and flying smoothly.
If you watch the video, you can know that it is not easy to ride in the H-6, the fighter plane is constantly bumping up and down, sitting on the seat, and the feeling is similar to that of a big truck.
Inside, the pilot struggled to control the plane to keep it flying smoothly, while in the turret of the cannon in the back, the guide of the tanker aircraft was also concentrating on guiding the two planes that were approaching.
In order to ensure the success of refueling, some special equipment was installed on the aircraft, for example, two sets of TACAN navigation systems were installed for aerial ranging between the refueling and receiving aircraft, and short-range navigation and orientation to the ground.
The principle of this system is very simple, of course, the first thing that must be had is the knowledge of polar coordinates, which is actually a polar coordinate system with itself as the center point.
It requires distance and azimuth, and the distance is determined by sending pulses, sending 30 pairs of interrogation pulses per second with an interval of 12 microseconds to the other party, and the other party transmits the same interval of answer pulse pairs after receiving the interrogation pulse pair. In this way, superimposed back and forth, and by comparison, it is possible to get the time of propagation of the pulsed radio wave in space, and thus the distance between the two sides.
As for the azimuth, it is a bit more troublesome, and the radio waves it emits are rotating, and the waveform is in the shape of a heart with 9 lobes, and it rotates at 900 rpm. After the aircraft receives the amplitude modulated pulse signal, it adds the reference model and compares it to obtain a fairly accurate bearing.
This is also to be able to find each other, generally speaking, due to the large number of people on the tanker, there are special refueling guides, therefore, the refueling guide calls are more, he has a special radio here, and can directly call and contact the refueling machine.
Now, air refueling is still a blank in the country, only the introduction of air refueling pods for imitation, the rest, all need to be personally studied and pondered, as a refueling guide of the young man, there at this time is also a little nervous, he with his bright eyes, looking at the airspace in front, there, two silver-white fighters, are slowly leaning over.
Twenty kilometers away, even if there is no guidance, just by sight, the target can be found, Qin Feng and Lao Chang, at this time, side by side, flew forward.
If refueling and docking are carried out, then at the beginning, it must be carried out one by one, but now, when simulating flight, it is also useful to fly together on the left and right, after all, when the real refueling is carried out, it is on the left and right, refueling at the same time, if it is a larger tanker, or even a refueling pipe in the tail, three can be refueled at the same time.
Now, the two of them were flying forward in a horizontal formation, and Qin Feng was steadily controlling his fighter plane, gradually approaching.
Watch out for turbulence at the tail!
It's like a building, when the wind blows through the building, it will form a high-pressure area on both sides of the building, and a low-pressure area will be formed behind the building, and this is the same for this flying tanker, and behind its fuselage is a turbulence area that is sometimes high and sometimes low.
"A hundred meters away, keep getting closer."
Now it is only the initial training, so the air tanker does not stick out its own air refueling tube, but only flies in formation.
"Eighty meters away."
"Sixty meters away. Pay attention to adjusting your posture. ”
Fifty meters away!
The two Jian-8 fighters flew side by side, and the lateral distance between them was only a few meters, after all, they flew behind the wings on the side of the tanker, and the distance between the two sides was not long.
Qin Feng turned his head, glanced at it, and wanted to roar on the radio, Lao Chang, you didn't shave today!
