At 8 o'clock in the morning, the weather was cloudy, the temperature was 5 degrees, there was no sustained wind direction, and there was a light wind.

"301, ready to take off, over."

The 301 J-10C stopped steadily on runway No. 1, ready to go, Yang Luo sat in the cockpit, and the sweet voice of the tower commander came from his ears.

Well, it's a girl.

This commander's sister and yesterday's commander are both from the staff of the 75th Division, and the Kat Field Station was originally a station under the leadership of the 75th Division, and a brigade of the 63rd Regiment of the 75th Division was stationed before.

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

Last night, I took Xue Fei on a flight, and I flew in a night formation.

Today, Yang Luo is going to go up alone, carefully check the terrain of the Hengduan Mountains, prepare for the follow-up training, and enjoy the beautiful scenery of the Hengduan Mountains by the way.

Push the throttle valve, release the brake,

"Boom!"

The Al-31FN aero engine began to roar violently, pumping out high power, pushing the bulky fighter plane to accelerate to takeoff.

More than ten seconds later, the 301 J-10C took off into the air, and the Roc spread its wings into the gloomy sky.

The runway of the CAT station is southwest-northeast, the northeast is an open area, there are peaks more than 10 kilometers away, and the southwest peaks are very close, only about 3 kilometers.

Since there was no sustained wind direction, there was no headwind to take off, so Yang Luo directly chose to take off in the southwest direction, saving him a U-turn.

At this time, it looks like the 301 J-10C is directly hitting the mountain.

However, how could it really be bumped.

The peak is 3,500 meters above sea level, which is only 1,400 meters above sea level, compared to the 2,100-meter altitude of the Katat station.

At a distance of 3 km, it is enough for the J-10C to climb to an altitude of 1400 meters.

Adjust the angle of the flaps and canards, so that the 301 J-10C can climb in height at the maximum angle of attack.

Six seconds later, the altitude had climbed to 1,600 meters, and it swept past the summit and continued the climb.

Yang Luo then changed the altimeter to standard atmospheric pressure, and the altimeter, which originally showed an altitude of 1,600 meters, instantly changed to 3,700 meters.

Most of the peaks in the Hengduan Mountains are between 4,000 and 5,000 meters above sea level, so Yang Luo raised the altitude to 6,000 meters and flattened it and did not continue to climb.

"The Hengduan Mountains are truly beautiful."

Piloting the fighter plane at a constant speed, through the cockpit glass, Yang Luo enjoyed the beautiful scenery along the way, and at the same time carefully observed the terrain.

Below are the undulating peaks, most of which are covered with snow, and the vegetation coverage below the peaks is extremely high, making them green and vibrant, and the valley floors are of different heights and great drops.

The Jinsha River, the Lancang River, and the Nu River flow side by side, rushing all the way through them.

"Hey, is it the Brahmaputra Grand Canyon ahead?"

After flying for more than 20 minutes, a huge canyon appeared in front of Yang Luo's eyes, and after glancing at the theodolite, Yang Luo was sure that it was the Yarlung Zangbo Grand Canyon, a tourist destination that travel enthusiasts yearn for infinitely.

As soon as he pressed the bar, Yang Luo swooped down, his movements were clean and neat, without the slightest drag of mud and water.

Others are admiring the grandeur of the Yarlung Zangbo Grand Canyon on the ground, while Yang Luo wants to watch it from the air, and at the same time wants to determine whether the Yarlung Zangbo Grand Canyon can be used as a training point for low-altitude penetration.

Just because this Grand Canyon is long enough, reaching more than 500 kilometers.

The only uncertainty is the strength of the turbulence in the canyon, which has an average depth of 2,268 meters and a maximum depth of 6,009 meters.

"Call the tower, is there any turbulent distribution area about the Yarlung Zangbo Grand Canyon at the station?" Yang Luo asked through the radio communication channel.

"Tower received, 301, are you going to enter the Grand Canyon?" The conductor asked in her sweet voice.

Looking at the Grand Canyon getting closer and closer, Yang Luo replied, "Yes, Tower, I think the Grand Canyon is a good training location. ”

"301, don't mess around, the turbulence in the Grand Canyon is very complicated, you can't explain it clearly in a word, you better come back and check it out for yourself." The commander girl persuaded.

"Tower, don't worry, I won't mess around, okay, don't say much, I'm going into the canyon." Yang Luo said with a smile.

“……”

The commander's sister opened her mouth, but in the end she didn't say anything.

Yang Luo put out the speed brake, reduced the airspeed, and entered the Grand Canyon for the first time, not knowing the specific distribution of turbulence, too high airspeed is to find death.

After the airspeed was reduced to 500 kilometers per hour, Yang Luo put away the speed brake, leveled the fighter, and concentrated on controlling it, and plunged into the Grand Canyon.

The signal of the 301 J-10C disappeared on the radar screen, and the commander's sister's heart suddenly rose, and her face was full of worry, only the communication between the 301 J-10C and the satellite reminded her that the 301 was fine.

Mountains are on the left and right, and the river is rushing below, and from top to bottom, the width gradually closes and becomes smaller.

After entering the Grand Canyon, Yang Luo changed the angle of the flaps and canards, so that the angle of attack was reduced, the lift was reduced, and the purpose of slowly descending in height was achieved.

The canyon depth is 1,680 meters, and the altitude is 1,200 meters.

As the altitude continued to decrease, the flight attitude of the 301 J-10C was gradually affected by turbulence, and the fighter began to shake.

But when it descended to an altitude of 1400 meters, it was only 200 meters away from the valley bottom, and the wings on the left and right sides shook very much, and the 301 J-10C went up and down, as if entering high-altitude turbulence.

The turbulence in the canyon was even more powerful than expected, and Yang Luo struggled to maintain it for a while, but he had to pull up a height of 200 meters.

With this kind of turbulence intensity, Yang Luo can actually control the fighter, but he is afraid that the turbulence in front of him will intensify, and the relatively low altitude is too low, and the danger is too high.

Relative to the area at an altitude of 400 meters from the valley floor, the intensity of the turbulence has weakened by more than one level and is completely in a controlled area.

The danger of the Yarlung Zangbo Grand Canyon is not only the turbulence in the valley, but also its winding waterfalls.

After flying for more than ten minutes, Yang Luo encountered a danger, so scared that he almost ejected and parachuted, but fortunately he stabilized.

Here's the thing, Yang Luo, who was flying well and enjoying the beautiful scenery along the way, suddenly found that the canyon in front of him had turned, and it was still very dead.

Yang Luo didn't care about it at first, he was just ready to make a turn, but when he got closer, he found that there was a big problem with this turn, and it turned out to be a 180-degree U-turn.

Yang Luo was taken aback, but fortunately, his strong mental quality did not make him scramble, and he made the right response in an instant, quickly made a Herbst maneuver, and made a 180-degree turn.

However, when the fighter climbed to the highest point and the airspeed dropped to the minimum, a downdraft struck, and the altitude of the fighter decreased rapidly.

At this moment, Yang Luo's face turned white, and he almost ejected and parachuted, and hurriedly pressed the pole to dive, and when the height from the valley bottom broke through 100 meters, the fighter gained enough speed.

However, the turbulence at the bottom of the valley is too complicated, it has been shaking violently, and the fighter has gained speed but has been entangled by the turbulence, and has not been able to climb the altitude normally.

At that time, the fighter was already at the maximum angle of attack, the throttle valve had reached the maximum, even the afterburner was opened, and the aero engine was at maximum power.

has been struggling for more than 20 seconds, the altitude has not increased, and he has been hovering around 100 meters, Yang Luo's forehead is already sweating, and his hands are operating like phantoms, constantly adjusting the attitude of the fighter.

Fortunately, at this time, an updraft passed by, and Yang Luo seized the opportunity, got rid of the influence of the turbulence, and pulled the height of the fighter back to an altitude of 400 meters.

When he returned to the altitude of 400 meters, Yang Luo couldn't help but take a deep breath of onboard oxygen to soothe his frightened little heart.

This is the most dangerous flight since Yang Luo learned to fly, compared to the last time he encountered the high-altitude turbulence, floating and sinking at a height of 100 meters, it is really frightening, and there is a sense of powerlessness.

You must know that at a height of 100 meters, even if you parachute to escape, the chance of survival is very low, and it can be said that you are dead and dead.

After regaining altitude, Yang Luo did not return home, but continued to fly along the canyon, but became more cautious.
