Su Peng was wearing a training uniform, standing beside No. 008 J-10D, with a serious face, pointing to the air refueling pipe in the nose with his right hand, and explained carefully:

"The rendezvous is a regular rendezvous and a route rendezvous, which will be arranged in advance, and the tanker will fly along an elliptical route, and only the straight lines on both sides of the ellipse will be the refueling section. Docking is the most difficult link in the whole refueling process, it is necessary to make the refueling pipe and the oil pipe accurately connected, our army refueling aircraft adopts hose floating anchor air refueling technology, and the hose refueling interface is extremely sensitive to air turbulence, which leads to the extremely difficult docking process and high danger. ”

Zhou Hai sat on a small military bench, holding the technical information on air refueling in both hands and explaining it in detail, without the slightest impatience, quietly listening to Su Peng's explanation and absorbing useful experience.

Although useful experience is better than nothing, Zhou Hai has already memorized the knowledge content of the theoretical course, and after hundreds of thinking simulations, he has completely mastered the technology of in-flight refueling.

However, the attitude must be correct.

Only by studying patiently, maintaining the initial attitude, and being down-to-earth can you master more things and eventually climb to the top step by step.

Soldiers, be arrogant and impatient!

"The refueling stage, the second difficulty, after the smooth docking and refueling operation, the fuel enters the fuselage fuel tank, resulting in a change in the center of gravity and balance of the fuselage, but there is no need to worry about this, the fourth-generation optical control system and intelligent avionics system adopted by J-10D will automatically adjust the state and speed of the fuselage, as long as there is no error, it will basically not be disconnected from the connection and cause aviation fuel to fly wildly"

Looking at Zhou Hai, who was concentrating, Su Peng's face remained unchanged, and he continued: "As for the disbandment link, it is generally called detachment, as the name suggests, disconnect from the refueling machine, quickly leave the refueling area, and give up the position, understand?" Generally speaking, it seems that air refueling, which seems to be more difficult, is not as good as carrier-based aircraft taking off and landing at night. ”

At the end of the conversation, the most familiar mantra came out.

The difficulty of air refueling and night take-off and landing of carrier-based aircraft is not at the same level at all, and the former can be easily mastered as long as you are willing to work hard to learn and accumulate time and experience.

As for the latter, only the most elite naval carrier-based fighter pilots can carry out night take-off and landing flights on aircraft carriers, which can be called rare.

"Understood."

After listening to this, Zhou Hai nodded.

"That's okay, get ready to get on the plane, just talk about the theory casually, I guess you know it."

Su Peng smiled at Zhou Hai and said, "Today's two-plane formation, Comrade Lao Yang's training requirement for you is to succeed in docking within three times, and I hope you succeed at one time." ”

After the words fell, he gestured to Liu Honglin, the leader of the second squadron of aircraft maintenance, who had just finished his work, and signaled to prepare for takeoff.

Zhou Hai exhaled a breath of turbidity, got up and put away the technical information in his hand, turned around and picked up the tactical tablet and backpack placed next to him, and prepared to board the plane.

Saying a thousand things and ten thousand is the most practical thing to carry out actual training.

Squadron leader Liu Honglin and several ground crew members were busy, adding fuel and carrying out pre-takeoff inspection work around the airframe.

Not long after, the two J-10D 'Fire Dragons' were ready, and Su Peng's landline took off first, and the small tractor pulled out of the parking position and came to the take-off section of the hangar.

"See you in the sky, Zero."

Su Peng, who entered the cockpit along the boarding ladder, put on a bright and dazzling golden helmet and shouted at Zhou Hai.

"See you in the sky, Overlord." Zhou Hai waved his hand and responded.

The No. 008 J-10D glass cockpit cover slowly closed downward, and after more than ten seconds, the turbofan engine was successfully started, and the heavily armed Su Peng gave a thumbs up to everyone, controlled the warhawk to start smoothly, and drove away from the No. 2 cave hangar.

Zhou Hai followed, put on a sharp-eyed helmet, boarded the brand-new No. 012 J-10D 'Fire Dragon', sat upright on the cockpit ejection seat, confirmed fingerprints and voiceprints, turned on the avionics system, and waited for a self-test, and then cooperated with Liu Honglin and others to start the engine.

Everything follows the flow, familiar and smooth.

Today, the second flight after the solo flight.

"Buzz!"

More than ten seconds later, with a blue high-temperature tail flame coming out of the jagged nozzle, the entire J-10D 'Fire Dragon' left the hangar, passed through the passageway, and headed for the main runway of the base.

In the distance, the No. 008 J-10D, which was running at high speed, had already raised its proud head, changed the angle of attack of the fuselage, and swept towards the clear blue sky, and the gentle morning light shrouded the body, as if wearing a golden suit.

Zhou Hai did not hesitate, after the tower gave take-off permission and ground parameters, he turned into the main runway, pushed up the throttle valve, accelerated the taxi, and faced the blue sky.

"Call zero, here is the Overlord, climb to an altitude of 11,000 meters, the mission route and related data have been transmitted, the tanker model is Il-78, the target airspace is located 200 kilometers to the northwest, the refueling altitude is 4,500 meters, and the weather forecast shows cloudy." In the encrypted radio communication channel, Su Peng's voice was immediately heard.

"Zero has been received and is climbing."

Zhou Hai pulled the lever back, maintained the horizontal attitude of the airframe, and clicked to view the relevant information about the target airspace.

The Il-78 tanker aircraft, developed from the basic prototype of the Il-76 strategic transport aircraft, uses four high-bypass ratio high-thrust turbofan engines, and is known as the "king" title in the field of tankers, and its comprehensive performance far exceeds that of the American-made KC-135A tanker, and the maximum fuel supply capacity of the basic model is as high as 65 tons, which can easily meet the fuel needs of 10 J-10D.

The latest improved Il-78M tanker has a maximum fuel capacity of up to 106 tons, standing at the pinnacle of the world's tanker sequence, greatly improving the long-range combat strength of the air force of the equipment country.

Zhou Hai steadily maintained a climbing state, controlled the war eagle under him, swept towards an altitude of 10,000 meters, and complemented the No. 008 J-10D not far away, adjusted the flight spacing and attitude, and formed a two-plane formation.

More than a minute later, the two warhawks passed through the clouds at medium and low altitude like sharp swords, climbed to the predetermined flight altitude, the jagged vector vent almost ignored the effect of the thinning of the atmosphere at high altitude, adjusted the angle, and cooperated with the canard wings to give the body excellent maneuverability, like a swift, dexterous and agile, easy to change, in sharp contrast to the previous J-10S and L-15C Falcon.

The altitude is 11,000 meters, and the speed is Mach 0.8.

"Zero, I'll ask you a question." After changing to fly smoothly along the route, Su Peng's somewhat confused voice sounded in the radio channel.

"What's the problem? Overlord. Zhou Hai was puzzled.

Su Peng said slowly: "Do you say it's better to fly the J-20 or become an astronaut?" ”

"Astronauts?"

When Zhou Hai heard this question, he was stunned for a moment, and his eyes couldn't help but cast his eyes on the sky above his head.

At the top of the firmament, and beyond that, is the starry sky!

Su Peng suddenly asked what this was for?

Wait, is it said that astronauts are going to be selected above?

"There will probably be a group of astronauts recruited in the next two years, and I am a little hesitant and don't know whether I should sign up." Su Peng said slowly.

PS: Su Rui is Zuo Xue's mentor, Su Peng is the leader of the Haiyan squadron, the elite of the Golden Helmet, I confused the two when I coded words before, sorry.
