Yang Luo turned on the on-board radio station and contacted the tower, "Call the tower, 301 is ready, request to slide out, over." ”

Immediately afterward, the sound of the other three people requesting to slide into the runway sounded in the communication channel.

This take-off is a formation take-off, the first formation take-off since the J-10C modification training, today is not only a control function refueling training, but also with a formation take-off training.

"The tower received, 301,221 slid into runway 1, 304,305 called into runway 2, can slide out, over."

"301 Roger, over."

Yang Luo signaled to the front, and then under the command of Qi Yu, the first one slid out of the hangar, passed through the tarmac in front of the suffering, entered the taxiway, and finally arrived at the runway to brake and stop.

Xue Fei's 221 J-10S followed, entered the No. 1 runway, braked and stopped at Yang Luo's right rear, Xu Zhiqiang's 304 J-10C and Wang Hanyu's 305 J-10C stopped one after the other on the No. 2 runway.

Since Yang Luo became the squadron leader, he finally got rid of the fate of the wingman and began to fly the long plane, Xue Fei was more sad, he used to be Zhao Long's wingman, and now he is Yang Luo's wingman.

Yang Luo saw that Xu Zhiqiang and Wang Hanyu were already in place, and called the tower again, "Call the tower, the first squadron requests to take off, perform the air refueling subject training, over." ”

"The tower received, the ground wind direction is 355, the wind speed is 4 meters second, the crosswind wind direction is 250, the crosswind wind speed is 3 meters second, the field pressure is 1002, and the four-plane formation takes off, it can take off, and it is over."

"301 received, ready to take off, done."

"221 received, ready to take off, over."

"304 received, ready to take off, over."

"305 received, ready to take off, over."

Yang Luo took a deep breath, pushed the throttle valve, released the brakes, the engine roared, and the 301 J-10C ran from slow to fast on the runway.

Almost at the same time, the other three people were doing the same operation as Yang Luo, and after the four rolling torrents slid over the two runways for more than three hundred meters, they raised their proud heads almost simultaneously and faced the blue sky.

The landing gear is slowly retracted into the belly, and the landing gear door is then closed, steered, and climbed.

"Attention everyone, the climb to an altitude of 9500 meters, the course 225, the mission-related data has been transmitted, the air tanker type is the Il-78, the target is located at the 225 course 300 kilometers." In the communication channel, the voice of the tower was heard.

"XXX received, done."

After Yang Luo responded, he clicked on the task-related data sent by the tower.

Il-78 air tanker, converted from the Il-76 military transport aircraft. The Il-76 was delivered in 1978 and the Il-78 entered service in 1987. This tanker is mainly used for mid-air refueling of long-range aircraft, front-line aircraft, and military transport aircraft, as well as emergency fuel delivery to mobile airports. The aircraft adopts a three-point air refueling system, which can refuel 3 aircraft at the same time.

The maximum take-off weight of the Il-78 is 190 tons, and it can refuel 65 tons for other aircraft when flying 1000 kilometers, while the fuel tank capacity of a J-10C is only about 5 tons, that is to say, an Il-78 air tanker can easily meet the fuel needs of thirteen J-10C flights at the same time.

Yang Luo held the control stick steadily, maintained the climbing state, and controlled the J-10C to sweep towards the altitude of 9500, forming a four-plane formation with the three planes on the right.

In less than a minute, the four fighters passed through the low and medium clouds, climbed to a predetermined altitude of 9500, and then easily changed out and rushed to the airspace 300 kilometers away.

There were no words along the way, and after more than ten minutes, the four fighters crossed a distance of 300 kilometers and arrived at the target area of the control function for refueling.

A giant Iron Bird is already waiting in the target area at an altitude of 8,500 meters, and it is circling, it is none other than the Il-78 air tanker.

"221, 304, 305 will wait in mid-air first, and 301 will train first." In the communication channel, the voice of instructor Ren Shaoping, who was sitting in the rear cabin of the 221 J-10S, sounded, "301, reduce the altitude to 8500 meters, prepare to converge, and refuel at a speed of 550 kilometers per hour." ”

"301 received, lowering altitude, ready to converge." Yang Luo said, with a serious face, looking at the lower altitude control function tanker Il-78 in front of him, his right hand gently pressed the lever, the speed brake was erected, and the height was gradually reduced, ready to meet with the Il-78.

The refueling pod under the belly of the Il-78 has released a 26-meter-long refueling hose that swings slightly in the air and is fitted with a funnel-shaped cone at the end.

Steadily reducing the altitude and speed, the 301 J-10C entered the rear and lower part of the Il-78, and flew about 5 meters below the rear of the refueling hose about 3 meters, maintaining the speed synchronized with the Il-78, and flying in formation before refueling.

Above Yang Luo's head, the four aircraft engines of the Il-78 continuously eject high-temperature airflow, forming turbulence in the rear, which is one of the dangerous factors for in-flight refueling.

Once the fighter plane flying below accidentally enters, it is easy to have an accident, and what is more dangerous is that if the fighter inhales exhaust gas in the air intake, it may also cause engine failure and even stop in the air.

"Call 301, this is KY-01, allow your plane to start refueling in the air." In the encrypted wireless channel, an unfamiliar signal was accessed, and it was the person in charge of the Il-78 air tanker above his head.

Air refueling, mainly air tankers, follow the instructions of the person in charge of air tankers.

"301 received, ready to approach docking." Yang Luo replied, raised his head slightly, and looked at the refueling hose cone sleeve three meters above the front.

The left hand gently pushed the throttle valve, slightly increasing the speed of the ship, just less than two meters per second above the speed of the Il-78, almost imperceptible, and the right hand gently pulled the rod back, climbing at an invisible speed and elevation angle.

Under the watchful eyes of everyone in the Il-78 and the pilots and instructors of the three fighters, the 301 J-10C was moving at a very slow speed towards the refueling hose under the belly of the Il-78.

Two meters!

One meter!

"Okay, okay, steady, hold on, you three learn a little and see how your squadron leader operates." In the communication channel, Ren Shaoping's voice sounded, and there was a hint of nervousness at first.

Xue Fei and the other three have separated and did not maintain a formation flight, but circled around the Il-78 at three different altitudes, scanning back and forth on the course and the J-10C, while Ren Shaoping, who was in the rear cabin of the J-10S, watched the 301 J-10C in slow motion intently.

At such a close distance, there was still dangerous turbulence in the sky overhead, and the three pilots were quite nervous when they saw it.

The altitude difference of twenty-six is too low for an aircraft, a little with a rod, with the climb rate of the J-10C, it does not take a second, only 01 seconds.

Yang Luo was very calm in his heart, staring at the refueling hose cone sleeve in front of him, without hesitation, he controlled the fighter plane to climb slowly, and aligned the oil receiving pipe on the right side of the windshield with the refueling cone sleeve.
