After lunch, the three of them returned to the No. 1 factory area of the base together, Academician Yang Wei supervised the production of J-20, Zhou Hai did not delay, went to the office to get a training backpack with flight equipment, and prepared to leave by car.

After the solo J-10S returned to the Huangtianba base, it was necessary to return to the base immediately and fly the J-10D 'Fire Dragon' solo for the first time to carry out the flight mission of a single plane with a long-distance transfer.

For the J-10D 'Fire Dragon' in the No. 2 cave hangar, Zhou Hai couldn't wait to experience the inexplicable excitement of the cave room.

Passing through the highly confidential J-20 pulsating production line, bidding farewell to the brand-new war eagle parked at station 1, Zhou Hai and Lin Jian left the base factory together and came to the hot outside world, the base parking area.

A sky-blue Air Force painted warrior military vehicle, quietly parked in the parking space, with an air force second lieutenant officer on it.

It's noon, and the outside world is like a furnace in direct sunlight, and the heat wave twists and rolls.

"Zhou Hai, in addition to your physical fitness meeting the basic conditions of the flight mission, it is inseparable from the excellent performance that has always been performing.

After leaving the base factory with many personnel, Lin Jian glanced at Zhou Hai, his words were calm and powerful, and he instructed: "Tomorrow will start the training of air refueling technology, I will only give you eight days, be sure to master the air refueling technology before the official start of the mission, otherwise there will only be a replacement, understand?" ”

It is far more risky than normal for a new flight that has just been released to fly solo to carry out the task of ultra-long-distance non-stop flight around the national airspace.

If it weren't for Zhou Hai's excellent performance in the four stages of initial education, higher education, special training, and military exercises, coupled with the fact that he was unexpectedly lifted from the solo flight restrictions, it would not have been Zhou Hai's turn to carry out this task.

"Understood."

For this rather mysterious Colonel Lin Jian, Zhou Hai's face was stable, without any change, and he nodded and replied.

Why mysterious?

That is, he is not a member of the Pengcheng base, nor is he Zhou Hai's direct superior, Lin Jian, who is only with the rank of colonel, has the power to arrange his flight training, which means that he can directly interfere with the normal operation of the Pengcheng base.

Not only mysterious, but also extremely special.

The only explanation is the confusing 'metamorphosis plan'.

"After completing this mission, I will officially introduce you to the content of the transformation plan, there may be a series of important tasks for you to perform, first remind you." Lin Jian's voice was calm and solemn, and he stood at the back door of the warrior military vehicle: "Get in the car." ”

"Okay."

Zhou Hai nodded, opened the rear door, carefully sat in the car with a training backpack, and then closed the door.

"Buzz!"

The most familiar diesel engine sounded, and after Zhou Hai sat down, the second lieutenant officer remained silent, strictly abiding by the principle of confidentiality and the needs of the task, holding the steering wheel with both hands, and controlling the warrior military vehicle to start smoothly and drive along the base road.

"Goodbye, number 203."

Zhou Hai stared at the J-10S fighter surrounded by many ground crew at the No. 8 parking stand in the distance, and said goodbye silently in his heart.

This No. 203 J-10S accompanied Zhou Hai for thirteen days, allowing Zhou Hai to complete the modification training, from immature new flight to qualified new flight, and experience real fighter flight for the first time.

We don't get together much, but it's crucial.

Say goodbye to the concubine who has a different taste, and today, go home and live with the eldest wife!

Not long after, the entire warrior military vehicle left the Huangtianba base, drove along the planned route, passed through the bustling and lively Wencheng District, passed by the old city, went straight to the ring highway, and headed for the Pengcheng base 80 kilometers away in the north.

At the same time, taking advantage of the short time to return to the base, Zhou Hai, who has always held the idea of 'seizing the day', sat in the back seat and silently carried out the simulation calculation of air refueling technology.

Air refueling, through special special tankers, replenishes aviation fuel in the sky, thereby greatly improving the endurance of fighters, expanding the combat radius and range, and has an extremely important supporting role and indirectly increases combat effectiveness.

In order to meet the conditions of in-flight refueling, it is necessary not only to have a special tanker with superior performance, but also to master the extremely difficult refueling technology of the pilot of the tanker.

For pilots, this flying technique is like 'embroidery in the air'.

The refueling process requires the pilot to control a fighter weighing more than ten tons, or even twenty or thirty tons, to gradually maintain the same flight altitude and speed with the tanker, and to control the conical refueling pipe of the fuselage under the influence of changes in wind direction, wind speed and air pressure in the sky, and carefully dock the refueling probe like a funnel, requiring precision and zero errors.

Otherwise, the aircraft is likely to be hit by a metal refueling probe and a flight accident may occur.

The refueling docking process is similar to embroidery needle threading!

This is not the end, after docking, it is still necessary to maintain the balance and stability of the fighter and the oil receiving machine, and wait for the end of refueling before it can be separated.

There are no more than 30 countries in the world that can carry out air refueling, and the average proportion of fighter pilots who have mastered air refueling flight technology is only 30 to 50 percent.

Zhou Hai, who was running at full load like a computer, silently carried out a large number of mathematical calculations, conceived the process of refueling in the air of the J-10D "Fire Dragon", and carried out mental simulation.

Fifty times.

A hundred times.

Two hundred times.

Time passed minute by minute, the smoothly driving warrior military vehicle and the Pengcheng base were getting closer and closer, and Zhou Hai was constantly using his own advantages, synthesizing all kinds of mastered knowledge, and tirelessly repeating the entire process of refueling in the air.

Air refueling seems to be difficult, but in fact, the amount of calculation and the scope involved are far inferior to those of aircraft artillery interceptors, and they are at the same level as the original Herbst maneuver.

The afternoon sun is particularly dazzling.

At this time, the military vehicles galloping on the highway had already entered the boundary of Pengcheng, gradually reduced their speed, turned and left the national highway network from the ordinary exit, and then moved along the predetermined route under the guidance of the second-generation Beidou satellite.

Thirty minutes later, driving along the winding and wide secret road, the warrior military vehicle passed through two checkpoints to verify its identity and documents, and then it really arrived at the gate of the Pengcheng base.

"Squeak!" Coming to the gate of the base, the second lieutenant officer, who was in charge of the driver, stepped on the brakes and stopped steadily.

Zhou Hai came back to his senses, ended his thinking simulation about air refueling, and thanked the second lieutenant officer: "Thank you, comrade." ”

After the words fell, he opened the car door and got out of the car with his training backpack.

"No thanks."

The second lieutenant's swarthy and gruff face revealed a smile that contained a simple taste.
