"I haven't flown for a long time, and if I don't fly again, I'm afraid I will need to go back to the aviation school for adaptive learning." Looking at the J-8 fighter that had just left the factory, Qin Feng said to Wang Yang on the side.

"Yes, this time, the Air Force is in a hurry, Qin Feng, have you memorized the route map?" Wang Yang said to Qin Feng.

Qin Feng stretched out his legs, and on his knees, there was a chart strapped to him, and the trajectory on it had been clearly marked.

"If you wait a few more days, you will be able to fly over with two planes, but now it is the same, from our factory to the air base near the capital, the landmarks are also very clear, and it is said that the flight is good." Wang Yang said.

At this time, this newly manufactured J-8 fighter is still the original model of the day fighter with the overall front hatch, because the air defense force in the capital area needs to be updated as soon as possible, so the air force is very tight, and this aircraft has just left the factory, and it needs to fly to the troops.

In this way, a pilot is needed to help fly over, and this task is also won by Qin Feng, if he doesn't fly, Qin Feng will really be unfamiliar.

At this time, on the wings of this J-8 fighter, an additional fuel tank was hung, which was completely a preparation for a long voyage, Qin Feng looked at Wang Yang, stretched out his hand, and shook it with his hand.

After the two shook hands, Qin Feng was just about to get on the plane, when he saw a girl trotting all the way to the factory, and a gust of wind came over, the wind blew her long hair, and the bow was also fluttering in the wind.

"Tingting?" Qin Feng looked at Gu Tingting coming over, the last time he was in the library, he talked until dark, and simply had dinner in the canteen of 601 again, Qin Feng also carried forward his style for the first time and sent Gu Tingting home.

After that, the two never met again, and this time, it was the second time they saw her, what was she doing here?

"Brother Feng, I heard that you came here for a test flight, so I'll come over to take a look, you're going to the capital this time, right?"

"Don't worry, after he passed, he will soon be back by train." Wang Yang on the side said: "Tingting, have you been nervous about your homework lately? Why haven't I seen you lately? ”

Gu Tingting glanced at him, she didn't know what she was holding in her hand, and stuffed it into Qin Feng's pocket: "Wait for you to get off the plane, and then open it." ”

If you are doing difficult actions, you can't put things in your pockets, and in the future, if you take your mobile phone with you when you get on the plane, take a photo, and post a circle of friends, I'm afraid it will be a serious warning when you come down, and you may even be grounded.

A big overload maneuvers down, and the phone will also turn into a terrible murder weapon.

But this time, there was no big overload flight action, just like a civil airliner, just fly over smoothly, Qin Feng's hand squeezed it in his pocket, it was soft, there was no rattling sound, it shouldn't be a letter or something.

Moreover, it was too late now, the ground crew was already waiting there, so Qin Feng saluted, then ran on the plane and climbed up vigorously.

The cockpit canopy was closed, the gangway was opened, and when the engine roared from the tail, Qin Feng's mind was empty, and he only thought about the task.

He didn't even look at Gu Tingting and the others who waved to him on the runway, and after calling skillfully, he slid onto the runway and flew straight into the sky.

Compared with the J-7, this aircraft climbed faster, and soon reached a cruising altitude of 8,000 meters, he aimed at the course and began this long flight.

Shenyang, goodbye, Qin Feng read silently in his heart.

The chart on his knee was very clear, and at the same time, Qin Feng kept looking at the various dashboards in front of him, and then silently calculated his route in his heart.

This is a big problem with long-distance flights, domestic fighters, and now there is no inertial navigation system.

The core of the inertial navigation system is a gyroscope, the gyroscope has stability, will not change with the state of the carrier aircraft, when the carrier aircraft changes, the angle of the carrier aircraft relative to the gyroscope can be measured, so that the dynamics of the carrier aircraft can be known, if the computer continues to accumulate this state, you can accurately know the direction of the carrier aircraft, and at the same time with the accelerometer, as long as you know the initial position of the fighter, you can know the next position.

This is the principle of inertial navigation used on fighters, it sounds simple, but high-precision gyro systems cannot be produced domestically.

Originally, the J-7 project introduced from abroad had an inertial navigation system, but the difficulty of negotiation made Tu Lao and others give up part of it, and the inertial navigation system and pulse Doppler radar were left to the J-8 to introduce.

Now, there is still a blank in this aspect, so the voyage of the fighter can only rely on this oldest way, look at the instrument of the fighter, calculate it yourself, if the brain is not good, then calculate it by hand, record it, keep recording, and finally get a complete route.

Civil aircraft have ground guidance stations along the way, but fighter jets, if they can fly on any route, there are not so many guidance stations to guide.

Qin Feng looked outside, blue sky, white clouds, this is really a good weather for flying.

It's been a long time since I've flown in this area, and a long-distance flight is a test of endurance and the ability to keep the route, which is really hard-won.

At the same time, it is also the best opportunity for Qin Feng to leave Shenyang.

Qin Feng knows that he can't fall deeper and deeper, he is in Chengdu, there is still a lot of work to do, now, the J-9 data is continuing to be sorted out, looking at the new era, how to develop a fighter suitable for future air combat in the new era on the basis of the J-9, at least put forward some theories, are waiting for him, although he is a test pilot, but has participated more in the research of the project, even if he knows that this project is just a self-entertaining project, it is also a pleasure.

The country has focused on economic construction, and I am afraid that there is no extra energy to build new fighters, and it would be good to mature the J-8.

Below, he has flown over the Great Wall, from here, seeing the Great Wall, it is like a giant dragon, lying on the land of the motherland, lying on the beautiful mountains and rivers, as long as he sees this, Qin Feng's heart can't help but ripple, this is the great motherland!

Flying over the Great Wall, getting closer and closer to the destination, Qin Feng was in the long flight, and the error of the route was not large.

When the fighter plane stopped firmly on the ground, the people of the field troops, who had been waiting impatiently, greeted Qin Feng enthusiastically.

"Comrade Qin Feng, I have already bought you a ticket to return to Shenyang." said the commander of the flying regiment.

"I'm sorry, please help me refund the ticket, can you give me a ticket to Chengdu or Xi'an?" Qin Feng asked with a smile.
