It takes a long time to find this fault, structural mechanics problems, aerodynamic problems, etc., before the root cause of the problem is found, the test flight of this 083 has been suspended, and during this time, Qin Feng has invested in the test flight of the Jian-8 oil engine.

On this day, the weather had just dawned, and when most of the people were asleep, Qin Feng had already arrived at the airport.

The forecast of the meteorological department is that the air flow is best in the early morning for the past few days, so they need to seize this rare opportunity to conduct a test flight in the early morning, especially since it is now the next stage of the project.

During this period of flight, the formation has been able to fly to a predetermined distance, so, next, is to really start docking, the initial docking, and will not refuel, as long as the oil receiving pipe is docked into the conical sleeve, it is considered a success, this way, called dry docking, only docking without refueling. In this way, you can be familiar with the docking refueling technology and evaluate the reliability and efficiency of the refueling docking system.

When Qin Feng came here, Lao Chang had already prepared in place, if you count from Lao Chang's initial preparations, he had been preparing for nearly a year in order to refuel in the air.

"Qin Feng, let's go, let's talk to Lao Shen." Lao Chang shouted Qin Feng, carried his helmet, and went to the tanker first.

Before each take-off, such a handover must be carried out first, and the air tanker and the refueling aircraft must be discussed below.

"Qin Feng, during this time, your progress has made us simply impressed." Seeing Qin Feng, Lao Shen said.

Lao Shen is the captain of the air tanker, and during this time, Qin Feng's performance is definitely enough to surprise them.

You must know that Qin Feng joined in halfway, and after flying less than thirty times in total, he had successfully completed the intensive formation training and was already able to reach the designated refueling distance.

Moreover, Qin Feng has not been conducting in-flight refueling training all the time, he also has to test fly other subjects, such progress is absolutely admirable, this is the level of an ace test pilot.

"Today, let Lao Chang come first." Qin Feng said: "If it doesn't work, I'll go again." ”

Qin Feng said this, of course, there is an element of modesty, when there is merit, he still has to give it to his companions, not to take credit, not to be arrogant.

Refueling in the air is of great significance to the aviation forces, the first dry docking will also go down in history, Qin Feng has the most first, the first flight of the J-7, and the recent first flight back in the case of the rudder dropping, it is enough to become a classic of the test flight institute, so Qin Feng pushed it to Lao Chang first.

After all, Chang Chang is almost at the age of grounding, and it is quite important to receive such an honor before the grounding.

"No, no, Qin Feng, it's better for you to come." Lao Chang immediately shook his head: "I see that you have practiced quite well during this time, and you will definitely be able to successfully connect at one time, so that our leaders can rest assured." ”

This test flight is of great significance, so after a while, many people will come, including the Air Force, the General Headquarters, the Ministry of Aviation Industry, the aircraft company, and the test flight institute, and everyone is looking forward to the success of this docking.

After more than a year of hard training, flying into the sky almost every day, Lao Chang has become an old black, and his face is tanned, just like Bao Gong, and now, he speaks sincerely.

"Lao Chang, you are my coach and my senior, this time, just listen to me, besides, we must also be mentally prepared."

Lao Shen nodded: "Yes, even if we usually practice very well, this time we really dock, we may encounter various problems, especially the fluttering of the umbrella cover after approaching, which is the most complicated, let's study and study it again." ”

Several people are studying, on the airport, a lot of people have come in one after another, everyone is waiting for this important moment, in the sky, the J-8 flew to a distance of 60.6 meters, and then plugged into the refueling pipe of the tanker, this is like performing acrobatics in the air, although it is difficult, although there is danger, but it must be overcome!

The plane took off, and the air tanker took off first, followed by the old Jian-8 and Qin Feng's Jian-8, following behind.

The three planes left everyone's field of vision one after another, and countless eyes were looking forward to it.

The huge body of the bombing oil six also slowly became smaller and smaller in the sky, and at both ends of its wings, two oil pipes suddenly stretched out, and the end of the oil pipe was a conical sleeve, at this time, the conical sleeve was dragged behind the wing, but it was very short, and when viewed from the side, it had not yet reached the tail of the tanker, which meant that if you want to refuel in the air, the real distance between the tanker and the tanker should be negative.

It's like flying underneath a big plane, and for the pilot, the pressure is great.

As usual, you often need to enter from the right.

Qin Feng's fighter plane accompanied behind, and the regular Jian-8 gradually approached the air tanker, in the last few trainings, they have often done this, and even recently, they have almost approached to the extent that they can dock, just like this.

Now, Lao Chang took a deep breath, and then, began to slowly approach, this movement must not be fast, otherwise it could bring disastrous consequences, Lao Chang's hand gently pushed the fighter, his dark face, revealing all determination.

Closer, closer, closer!

The distance starts at ten meters, goes to five meters, then goes to three meters, two meters, one meter.

At such a close distance, you can see that the tapered sleeve is flying in the wind, and it is also getting bigger and bigger, a circle larger than the pilot's helmet, so thick, can't it be docked?

Lao Chang continued to get closer, and when he was close to thirty centimeters, suddenly, the conical sleeve swished, and flew to the side!

Lao Chang's hand immediately released the throttle lever, and he couldn't get any closer, and if he got closer, there would be problems, for example, when this tapered sleeve was pulled back, it was like a whip, and it was whipped his plane!

In order to maintain the rigidity of the fuel filling pipe, in the outer layer of rubber of the oil filling pipe, it is a spiral structure made of steel wire, which is very strong and, of course, very dangerous.

As he released the throttle stick, the fighter plane immediately withdrew, and Lao Chang took a deep breath, and then, calming his mood, continued to start the next docking.

When the docking is unsuccessful, it is necessary to decisively exit and re-enter! This is also a plan that has been planned for a long time.
