"The engine stopped."

Li Zhan reported again.

This is really a in the snow, and the engine stops in the stall tailspin, which is a nightmare for a single-engine fighter. If there is motivation, there is still hope for changing, and if there is no motivation, there is almost only one way to fly.

"Try to start the airline once!"

No response.

"Try to start the airline a second time!"

"Try to start the airplane for the third time!"

……

"Trying to start the airborne...... Old man, are we all done? ”

You can already clearly see the mountains spinning towards you. What's even more terrifying is that it is difficult for the pilot to accurately grasp the altitude of the aircraft in the state of stall tailspin, and the aircraft will have a large delay in sensing instruments under a large descent rate.

Life and death are just a matter of seconds.

Li Zhan does not abandon or give up, and he will not pull the ejection handle until the end.

He tried to drive, tried to drive, tried to drive, tried to drive. Without motivation, everything is a floating cloud, but there is not much time left for him.

"Get it done, old man!" Li Zhan yelled and tried to drive again.

The pointer of the engine tachometer moved.

Li Zhan obviously felt that the fighter had the hope of breaking free, and he was overjoyed and pushed the throttle stick to the end, at this time, any attempt was an exploration, or a dead horse as a live horse doctor.

No. 037 J-7E actually accelerated and dived downward, but the flight attitude stabilized, and Li Zhan felt the feeling of regaining control from the feedback from the joystick!

In the midst of the roar, the auxiliary fuel tank under the belly of the fighter plane was almost pulled up against the tip of the mountain, drawing a beautiful and thrilling rollercoaster-like "U" shaped line in the air. After Li Zhan confirmed that the fighter was in level flight and the main systems were normal, he breathed a heavy sigh of relief.

"Lan Zhi, I changed it, changed it, I am over the mountains, ready to climb, you radar help me confirm the location, over." Li Zhan reported.

There was no echo from Lan Finger.

Li Zhan reported again, "Lan Zhi Lan Finger, I am Dong Sangui, I changed it, the sky above the mountain is ready to climb, you have to determine the altitude and course, over." ”

Lan Zhi still didn't hear back.

Li Zhan called again, "Lan Zhi? Hole three turn call, hole three turn call, over. ”

Still no response.

Li Zhan quickly recalled the position before the stall, and quickly judged the approximate position of the current - Guangyuan went up to the sky. In the 08 earthquake, there were many strong electromagnetic interference phenomena here, and the weather at that time was also very bad.

At this time, Li Zhan was flying under the clouds, the visibility was very poor, and the surroundings were gray, with both fog and low cumulonimbus clouds containing infinite dangers. Flying in the direction of about 300 degrees should be the Longnan area, where the terrain and weather will be more complicated.

The most important thing is that Li Zhan does not know the distribution of civil aviation routes and routes in the area, and it will be dangerous to make a rash choice.

"Sichuan Central Aviation Management, Beikudong three turns call, Sichuan Central Aviation Management, North Kudong three turns call, over." Li Zhan adjusted the communication frequency to the channel of the air traffic control duty room of the Southwest Military Region.

Since it was an inter-military flight, Li Zhan directly contacted Lan Zhi after taking off from the command of the tower after taking off, and the command post of the military region coordinated the route. Li Zhan was not sure whether it was because of the terrain or electromagnetic interference that had cut off his contact with Lan Zhi, and in this case, he had to call the Air Traffic Control Duty Room of the Southwest Military Region Air Force with a backup communication plan.

However, there was still no response.

At this time, Li Zhan could be sure that it was because of the terrain or electromagnetic influence that he lost contact from the communication channel. It seems that the electromagnetic interference factor can be ruled out when everything is normal in the instrument, but as we all know, the atmospheric radio waves are very complex, and there are many factors that affect communication, and electromagnetic interference cannot be simply eliminated.

Without too much hesitation, Li Zhan quickly made the decision to climb the height. Only by going up to altitude can you get rid of the influence of mountainous terrain on communications.

He remembered that there were several routes crossing in his airspace, most of which were concentrated in the airspace layer of 8,000 to 12,000 meters. But he couldn't remember the exact route very clearly. Upper altitude means intruding into the airspace layer through which civil aviation routes pass.

The Air Force has priority in the use of airspace in the same way that the Force has the highest priority in the use of ground roads.

The problem is that Li Zhan is in a state of communication loss at this time, and he has no way to contact the command post, so there is no way to make the civil aviation aircraft in the airspace where he is located. Having said that, if you can contact the ground command post, you can also get guidance to avoid the route of civil aviation.

This risk must be taken, otherwise Li Zhan will be a headless fly and have only one way to go: forced landing.

The visibility was very poor, Li Zhan climbed cautiously, eager to turn his eyes into radar, so he turned on the radar. The radar starts quickly, and the search action is fast, giving it a crisp and crisp feel. Li Zhan finally had some confidence, and his eyes kept looking ahead at the radar display. The entire cockpit has changed a lot, with a large screen display in the middle, two small screens on the left and right, and other instruments and buttons have also been redesigned, and even Li Zhan suspects that Cheng Luoma has transplanted the cockpit of the Thunder Dragon entirely.

However, Li Zhan did not have time to admire the new cockpit at this time, because the radar detected that there were seven targets flying in all directions in front of him. Judging from the reflected signals and parameters, it is either a large civil aviation aircraft or an air force aircraft. After quickly determining the altitude and speed of these targets, Li Zhan immediately had his own planned route in mind.

He adjusted the course height and cautiously entered the airspace layer where the civil aviation route was located, and at the same time adjusted the communication frequency to the channel of Lan Zhi and kept calling.

The weather was so bad that the electromagnetic interference was so loud that it was difficult to hear the instructions even if there was an echo.

Li Zhan can also choose to use the international communication frequency for blind transmission, and ask the aircraft in front to avoid him. However, radar detection has been used to open the way, so there is no need for Li Zhan to disrupt the flight plan of civil aviation.

He cautiously and stealthily crept his way through the ascent between several civilian airplanes, many of which had seen a fighter jet with a light gray paint all over them, flying higher and higher until they could not see it.

It is estimated that the civil aviation control center has been in chaos at this time.

？？？

What's the situation?

Why does a signal without a serial number appear?

After reaching an altitude of 13,000 meters, Li Zhan breathed a sigh of relief after resuming level flight, and at this time, communication with Lan Zhi was also re-established.

Lan Zhi also kept calling Li Zhan, and the breath of relief after re-establishing contact was even greater.

"Dong Sangui, I see you, adjust the heading 300, maintain the altitude, over." Lan Zhi gave the guidance instructions.

Li Zhan repeated the command and asked, "Lan Zhi, can I get down to the cruising altitude, I'm afraid that the fuel is not enough, over." ”

"Hole three turns to keep the height, over."

"Understood."

Obviously, the lower altitude would invade the airspace layer of civil aviation, so Lan Zhi rejected Li Zhan's request.

The oil is enough, Li Zhan's three auxiliary fuel tanks are all there, and they were not released before the loss, otherwise they would really be diverted. It's just that Li Zhan wants to leave some oil to soar when he returns to the vicinity of Beiku, he hasn't soared supersonic for a long time, and he can't sleep comfortably.

What is the difference between flying a fighter jet without soaring supersonic speed and salted fish.

Only now did Li Zhan have the heart to recall the strong air flow he had just encountered. He judged that at that time, he had just entered the space where the hot and cold air masses met, and the rapid strong side airflow should have come sideways from top to bottom, overturning the fighter plane in an instant, destroying the state of the wingtip stall lift body, and the fighter plane quickly entered a tail spin. If it was the SU-27, there would definitely not be such a big reaction. Although the J-7EGG is a modified version of the J-7, her double delta wing aerodynamic layout is the same as that of several other models, and the lift body is also the same.

Another reason is that the J = 7EGG is, after all, a light fighter and has no advantage in terms of dead weight. Under the same strong air current, if it is a civil aviation twin-engine medium and long-range passenger aircraft, it is estimated to be a strong turbulence.

Li Zhan recalled the disposal process and found an interesting place.

After the engine stopped and restarted, the plane changed its tail spin.

Is it possible to think that in the extreme case of encountering a tail spin that cannot be changed, the pilot can take the initiative to turn off the car and drive the aircraft to change the tail spin state?

This approach is extreme, and it is not clear whether it is exceptional or extensive.

Li Zhan secretly wrote down in the future to see if he could do an experiment, there was flying ginseng data, and all the situations at that time were based on facts.

After flying at a cruising speed for more than an hour, Lan Zhi asked Li Zhan to descend to an altitude of 3,000, and then handed over the command to Beikutatai. At this time, Li Zhan had already entered the desert in the basin, saw the national forest reserve that was familiar with Lake Ulun and the north of the lake, and also saw the short runway of Nankuchang Station.

With the feeling of returning home, Li Zhan was in a good mood, and asked Nie Jianfeng, who was on duty at the tower today, "Tower, I'll speed up the supersonic speed and test the high-speed performance of the fighter after the overhaul, over." ”

Nie Jianfeng said with a smile, "Dong Sangui, pay attention to the fuel balance, you can do it appropriately, over." ”

"Understood, over."

Li Zhan threw the three empty auxiliary fuel tanks in the desert, and then the throttle lever opened to the end. The engine nozzle of the No. 037 J-7E spewed out a scorching tail flame, which was very eye-catching at this time in the clear sky.

Today's weather in the Beiku area is very good, the snow has melted, and the ground temperature is between two or three degrees, which is a very comfortable winter day.

The fighter quickly broke through the sound barrier, Li Zhan was silently calculating the time, and the time to accelerate to break through the sound barrier was shortened a lot, indicating that the thrust of the new aviation engine that Cheng Luoma replaced with the No. 037 J-7EGG has increased significantly, and the thrust-to-weight ratio is greater. Could it be RD93? You can't fit that thing, can you?

It is estimated that it is an improved version of the Chengluoma Development Institute.

It shouldn't have something to do with the technology that my senior sister pulled back from the North Reservoir Station last year, right?

The airspeed is rapidly approaching Mach 15, and it is more difficult to increase the airspeed at 3,000 meters in the air. Li Zhan pulled the lever to climb, still full throttle. At this time, the empty weight of the fighter reached the best state, and the airspeed was actually increasing in the case of climbing.

In terms of acceleration ability, no one dares to admit that the J-7 is second, let alone the J-7EGG. Li Zhan fully experienced the thrill of supersonic flight, and was very satisfied with the state of the No. 037 standby aircraft after major modifications. After that, it's also pretty good to flip through her brand from time to time, and it's really vulgar to have a rod fee or not.

It's just that something happens every time she goes on a date with machine 037, and this is not a strong air current today. Others bumped a few times when they encountered strong air currents, and the No. 037 machine directly stalled and entered the tail spin to hit the mountain, but it was just impossible to think about it.

Li Zhan had already discovered that it was not that he had bad luck, but that Unit 037 was unlucky.

After passing the last landing navigation point, Li Zhan asked the tower, "Tower, I'll do a low-altitude and high-speed penetration, the course remains the same, it's over." ”

"Yes, pay attention to the attitude of the plane, over." Nie Jianfeng readily agreed.

This is the golden partner, and changing someone to command the tower must be forward-looking.

Li Zhan turned off the afterburner but confiscated the throttle, and instead directly pressed the lever to dive down the height. The No. 037 J-7EGG, whose airspeed was maintained at Mach 1.5, quickly gained huge energy in the dive state, and the airspeed climbed rapidly to Mach 2.

Li Zhan stared at the ground, and below was a familiar town area, which was the nearest residential area of Beikuchang Station, thirty kilometers away, and the name was Thirty Mile Town. The town is also an important landmark in the training airspace, a newly built two-lane first-class highway from south to north along the flat desert through the town to the Beiku Mountain Scenic Area, the main buildings are distributed on the central axis of the new highway, and the target characteristics are very obvious.

At an altitude of 200 meters, Li Zhan collected oil and pulled up, and the fighter plane soared over the town at supersonic speed, and when he turned to the left, Li Zhan saw that many people in the town ran out and waved wildly at him. The people were very enthusiastic, Li Zhan raised his right hand wearing white gloves and saluted, regardless of whether the people on the ground could see it or not.

Li Zhan is very familiar with the terrain here, and after informing the tower, he drove the No. 037 J-7EGG into the Beiku Mountains, and after a period of racing in the mountains, he directly rolled and flew out over the mountains, and the whole plane smashed on the three-turn route.

The personnel on duty at the North Kutar Station suddenly saw a fighter plane thrown out of the North Kuku Mountains due north, as if it had been thrown, and then the wild boy turned around and aimed directly at the runway, and the landing gear tires were released before the parachute landed, and the parachute was dragged in the air, and finally it only taxied more than 400 meters to reach the speed standard of leaving the runway.

Captain Falcon is back, and it's that familiar smell.

"Dong Sangui, you go directly to the maintenance plant, and the superior requires a comprehensive inspection of the aircraft and the flight ginseng is called out." Nie Jianfeng instructed Li Zhan.

Obviously, Lan Zhi's briefing came. The stall tailspin communication is interrupted, these are things to be checked. Checking the aircraft, checking the pilot, checking the ground radar station, and the navigation station, none of them is missing, and the normal procedure is just that.

"Dong San Gui understands."

Li Zhan smiled helplessly, only after leaving the aircraft factory and entering the maintenance plant, when will the No. 037 J-7EGG become a normal aircraft.

The thing that gave him a headache was still to come, at this moment, two Great Wall pickup trucks were rushing out of the town of thirty miles, and the enthusiastic people were rushing to the north reservoir station, and a chicken in the left hand and a duck in the right hand fully reflected the situation of the military and civilians......
