Xue Zhengrong came to the tower and sat in front of the ground command terminal of the tactical intelligence interaction system, analyzing the status of No. 037 J-7EGGHS.
The 167th Independent Flying Group now has four J-8Fs, two Su-30MK2s, one JH-7A and No. 037 J-7EGGHS, for a total of seven fighters. However, only the No. 037 J-7EGGHS has the most complete air-ground interaction information.
This legendary fighter plane is equipped with a large number of sensors, many of which were installed for various experimental tasks. There are more and more sensors and they have never been removed. It should be pointed out that this aircraft is still responsible for testing the tactical intelligence interaction system, from the first phase to the current third phase, and will continue.
Therefore, the ground commander can almost obtain the information obtained by the pilot from a third perspective at the same time, and may even be more aware of the external situation than the pilot. No. 037 J-7EGGHS is equipped with a 360-degree driving recorder, which is transmitted back to the background control center in real time through the 5G network.
The reason why Li Hai likes the No. 037 J-7EGGHS is because God knows that such a monster based on a second-generation aircraft can outperform all third-generation aircraft in battlefield situational awareness.
"Arriving at Airspace No. 2, we are ready to fly aerobatic maneuvers." Li Hai reported.
Zhao Feiyan looked at Xue Zhengrong, and Xue Zhengrong said, "You are the commander, you make your own decisions."
"yes."
Zhao Feiyan pressed the send button and said, "Dong Sanguai can proceed as planned."
"clear."
Two hundred kilometers away, Li Hai adjusted his course to due east and began to fly aerobatic maneuvers. Zhuang Xiaoying's flight helmet was equipped with a camera and she was holding the camera in her hand. In the first few maneuvers that were not too difficult, Zhuang Xiaoying was able to pick up the camera and take a few shots, such as flying upside down. Later, when the barrel roll, pendulum, hammer head, and Immelman were implemented... Zhuang Xiaoying could no longer lift her hands. Her body swayed with the changes in the three axes of the aircraft, and she was unable to complete a simple shooting action.
The pilot has to maintain control of the aircraft under such circumstances, and the difficulty can be imagined.
Xue Zhengrong suddenly remembered something and asked Zhao Feiyan, "Has Li Hai ever flown stunt subjects?"
Zhao Feiyan was stunned and said, "There must be no aerobatic flying subjects in the new training. He should..."
I can't say any more.
Li Hai had only flown a few times at the Flying Shark Base and had never flown any aerobatic maneuvers. After arriving at Forgotten Reef, he had been treated as a veteran. No one thought there was anything he couldn't do. Now that I think about it, it feels incredible.
After being silent for a long time, Xue Zhengrong shook his head slightly and said, "This kid is really weird."
"A weird genius." Zhao Feiyan smiled.
Dang Weimin, who came over a few minutes ago to enjoy Li Hai's performance, joked, "Maybe he is a reborn person, or someone who leads the system."
"You probably read too much on the Internet." Zhao Feiyan smiled and shook her head.
Xue Zhengrong said sternly, "Don't read those messy books, and read classics like The Plum in the Golden Lotus and Dream of Red Mansions."
"Xue Da, if the Dream of Red Mansions were placed today, the author would have to be imprisoned." Dang Weimin said with a smile, "There are many well-written books on the Internet now, and not all of them are anti-intellectual. For example, there is a book called The Great War. Falcon, the author of this book is a retired Air Force pilot. It’s very good, really.”
Xue Zhengrong smiled and shook his head. He didn't know how to read the Internet.
No. 037 J-7EGGHS was flying up and down, and the overload of many aerobatics was at six or seven G. In addition, Li Hai's speed and movements were always very violent, so that the whole movement seemed much faster than what the textbook required. .
Zhuang Xiaoying also followed Li Hai and played with 8G women. After this series of actions, she was a little bit too much and she was dripping with sweat.
What is too much is the nose landing gear.
The support pillars that have undergone qualitative changes have undergone obvious bending after such a drastic change in focus.
It's finally over.
"Tower, I'm going to stall and spin." Li Hai completed all the aerobatics and reported.
Xue Zhengrong looked at the distance and said, "It's too far away from this field. Let him fly back some distance, maybe fifty kilometers, and the altitude is six thousand."
Li Hai planned to start at an altitude of 3,000 meters. Xue Zhengrong thought it was not safe and made a change directly.
"The cave has three turns, a distance of fifty kilometers and an altitude of six thousand. Follow this implementation." Zhao Feiyan replied.
Li Hai did not insist and said readily, "Understood, the distance is fifty kilometers and the height is six thousand."
He pulled up the nose of the aircraft and turned on the afterburner to accelerate the climb. The unladen J-7EGGHS was very flexible and climbed to an altitude of 6,000 meters in a vertical attitude at one go. The temperature at this altitude is very low, the air is thin, and without an oxygen mask, human survival time is very short.
The short-term temperature change aggravated the damage to the nose landing gear support column, and surface cracks have already occurred due to thermal expansion and contraction.
Of course, various situations are taken into consideration when designing aircraft. In particular, fighter jets are usually used in extreme environments and have more stringent requirements. But that is based on the condition that the parts are in normal condition. If there is damage, the use method and intensity beyond the envelope will inevitably accelerate the deterioration of the situation.
For example, Li Hai habitually climbs vertically, which is not only a habitual action but also for the purpose of shooting some vertical afterburner climbing shots.
Under normal circumstances, this is without temperature.
But now the nose landing gear support column obviously cannot withstand temperature changes in a very short period of time and has suffered serious splits.
Maintaining level flight at an altitude of 6,000 meters, Li Hai carefully checked the status of each system of the aircraft and reported to the tower, "Tower, I am ready to implement a stall spin."
Xue Zhengrong took over the command and asked, "Dong Sanguai, do you remember the operating procedures?"
The personnel on duty in the tower were not surprised by this. If it were in other units, everyone from the commander to the pilot would be taken over. How dare you take off if you can’t remember the operating procedures?
Li Hai said, "No problem."
"It can be implemented." Xue Zhengrong issued the order.
Li Hai decisively shut down the engine.
Seeing the data displayed on the monitor quickly return to zero, Xue Zhengrong was a little confused. Zhao Feiyan had not been exposed to this subject yet and could not see anything.
Xue Zhengrong was about to ask, but suddenly remembered that this was J-7EGGHS No. 037, and swallowed the words that reached his throat.
Flying a stall spin does not require shutting down the engine, as long as the speed reaches the stall standard. In the past, aircraft required the assistance of a ground support vehicle to complete the engine operation. If a mid-air stop occurred, they would either have to glide and make an emergency landing, or abandon the aircraft and parachute. There was no third option.
Modern aircraft have APU (auxiliary power system), which can provide emergency power when the engine is shut down. Secondary driving in the air is no longer a problem.
The No. 037 J-7EGGHS looks smaller, but it is also equipped with an APU, and the unknown type of engine used by the aircraft has its own secondary driving capability.
Based on his understanding of the performance of the No. 037 J-7EGGHS, Li Hai confidently and boldly shut down the engine and quietly waited for the stall state to occur.
The No. 037 J-7EGGHS still uses a double delta wing, with the addition of a fuselage and a dorsal fuel tank. The air inlet has also been changed to clam inlets on both sides. The entire aerodynamic layout has undergone great changes, and the low-altitude and low-speed performance has been improved. Very good improvement.
Li Haiqing clearly saw that when the airspeed dropped to 160 kilometers per hour, the nose of the aircraft began to drop.
Entering a stall.
Soon it entered a spin.
The plane began to fall vertically downward.
Zhuang Xiaoying was startled. After vaguely seeing the height displayed on the altimeter, she almost screamed - she had dropped more than a thousand meters in just three seconds.
The plane's nose was spinning downwards, its tail spinning like a piece of paper on the edge of a vortex, getting faster and faster. Soon, Zhuang Xiaoying couldn't see anything anymore, she just felt that the world was spinning in front of her eyes.
In order to be closer to reality, Li Hai did not turn off the status alarm, and the cockpit was filled with a female voice of "warning, warning, warning" without any emotion.
Li Hai stared at the altimeter and made no further moves.
Xue Zhengrong couldn't sit still and said loudly, "Change, what are you waiting for!"
"Understood." Li Hai sighed inwardly and restarted the engine. He originally wanted to lose some height before making a recovery, but Xue Zhengrong didn't let him take the risk.
The engine was successfully driven for the second time and conditions were basically restored.
Li Hai operated according to the prescribed actions, with almost no bumps. No. 037 J-7EGGHS responded obediently, and the control rights returned to Li Hai's hands.
Finally, I pulled a lever and entered level flight.
It was over in a few seconds. Li Hai couldn't find the pleasure, nor the thrill of recovering from a stalled tail spin as he imagined. But Zhuang Xiaoying in the back cabin was so frightened that her face turned pale, and her head was so dizzy that she could not recover for a long time.
"The cave was turned around and we asked to return." Li Hai reported.
Xue Zhengrong breathed a sigh of relief and relaxed, "You can return to Dongsangui."
Li Hai glanced at the location of the airport, turned and adjusted the heading to the airport, and returned at cruising speed. At this time, the sun is behind, the weather conditions in front are good, and the sky is cloudless.
"Reporter Zhuang, how are you?" Li Hai then remembered to care about Zhuang Xiaoying.
Zhuang Xiaoying shook her head and whined, "It's okay, I'm just a little dizzy."
"It's normal. If you close your eyes for a while, you'll be fine." Li Hai said with a smile.
Zhuang Xiaoying wanted to vomit but couldn't. She felt quite uncomfortable. This was worse than a severe overload. In fact, it was like sitting on a centrifuge and being tossed around. It was good that she could still speak.
After seeing the airport, Li Hai turned left and flew for a few kilometers before resuming level flight. He visually checked the distance and relative position of the southern end of the runway. At five kilometers, he turned to the right with a large radius. After completing the turn, the nose of the aircraft was just right. Aim for the runway.
It's almost like a sideways parking style.
"Put down the landing gear." Li Hai pulled down the landing gear control lever.
All three lights were on green, and the front and rear landing gear were lowered normally. At this time, the flight altitude was 500 meters, and Li Hai was unusually cautious. According to past records, he usually lowers the landing gear when the altitude is below 300 meters and the distance is 2 kilometers.
No. 037 J-7EGGHS flew steadily towards the runway.
Suddenly, she fell suddenly, as if there were dozens of tons of rocks on her back, and as if the chair was suddenly pulled away from her buttocks, and she dropped more than two hundred meters in an instant.
When the sudden change occurred, Li Hai immediately grasped the joystick and pushed the throttle lever to the maximum throttle position. However, the effect was very limited. It was as if a strong slap was pressing down on the No. 037 J-7EGGHS from top to bottom, and the height was still falling!
"What's going on at Dongsanguai!" Xue Zhengrong asked urgently.
Li Hai had no time to answer. He felt a strong sense of powerlessness. No matter what he did, the situation of the plane's descent could not be improved. The entire plane fell in parallel, indicating that it was hit by strong vertical downward airflow.
Microbursts are invisible and undetectable deadly airflow conditions.
The microburst with strong winds pinned down No. 037 J-7EGGHS. It was only 500 meters high. Half of it was gone in an instant, and it hit the ground just a few seconds later.
The word "parachute" was stuck in Li Hai's throat, and he did not forget that there was another person in the back cabin.
A dead horse is a living horse. If it doesn't work, you must parachute decisively!
Li Hai turned on the afterburner and placed his hope on the engine. If enough power could be obtained in a very short time, the aircraft would be able to obtain enough lift!
"stand up!"
Li Hai used all his strength to pull back the joystick. At this time, the joystick was extremely heavy and had a large margin of movement. At this time, it was as stiff as rust!
The nose of the aircraft was slightly raised.
Suddenly, the resistance on the joystick decreased. Li Hai was caught off guard and pulled back too far, causing the nose of the aircraft to rise sharply.
At this time, the engine finally burst out with powerful thrust.
The engine roared and the fuselage groaned.
The tail of the aircraft dropped and the nose of the aircraft rose.
The tail of the plane was only fifty meters away from the sea, and it was still falling!
"Jump……"
Before Li Hai shouted the second word, the downward pressure suddenly relaxed, and No. 037 J-7EGGHS suddenly jumped forward and upward!
At this time, the tail of the plane was only more than ten meters away from the sea.
The powerful airflow ejected from the engine nozzle actually made a crater in the sea surface!
Li Hai quickly glanced at the position of the runway, decisively fine-tuned the nose of the aircraft, rushed out of the microburst range, flew close to the sea surface of the extended line of the southern end of the runway, and landed at an extremely exaggerated and small angle.
At this time, Li Hai had the energy to reply to the tower, "We have encountered a microburst. The party is for the people and it is really a crow's mouth!"
Xue Zhengrong didn't understand, so he turned around and asked Zhao Feiyan, "What do you mean? Is it related to the party serving the people?"
Zhao Feiyan's mouth twitched and she looked at Dang Weimin.
Dang Weimin was so embarrassed that he wanted to turn around and run away, and said to his scalp, "I said during breakfast that microbursts are more powerful. The weather is unpredictable during this period. I hope we won't encounter such weather..."
"Oh." Xue Zhengrong understood and smiled helplessly.
After the landing gear tires scraped against the runway and flew several hundred meters, Li Hai released his parachute and began to brake and slow down, finally stopping at the middle and rear section of the runway. He did not stop on the runway, taxied off the runway and returned to the open tarmac along the taxiway.
When No. 037 J-7EGGHS came to a complete stop, Li Hai breathed a sigh of relief.
He was about to open the canopy when the nose of the plane suddenly fell down!
The nose landing gear suddenly broke. No. 037 J-7EGGHS was like kneeling down on one knee after returning from a five-kilometer armed trip. I was so exhausted...
Li Hai and Zhuang Xiaoying in the cockpit were in shock. The hearts that had just been completely relieved were frightened at this moment and they took off vertically.
Zhuang Xiaoying murmured, "Flying a fighter jet is really not something ordinary people can do..."
