Under the work lamp, the No. 1616 J-16, which is full of all kinds of ammunition, gives people a super shocking feeling, thick and powerful, with a big waist and a round body and 12 tons of ammunition, like the ancient heavy armored cavalry.

Gently pushing the throttle stick, it was like the groom who had just experienced the night of the candles in the cave room once again slid to the take-off line, and the tower commanded down, and then began to accelerate and run, and it took a full 1,000 meters to pull up.

The pilot was Han Hongjun, who was the first time to take on such an important actual combat test flight mission, so he was very cautious in his operation. The rear cabin is the position of the weapon operator, and the J-16 is a fighter-bomber, focusing on ground strikes, and the rear cabin pilots must not only have skilled flight skills, but also have skilled ground attack capabilities, and are all-rounders.

When the tail flames of the twin spouts gradually faded away, Nie Jianfeng, who was commanding at the tower, breathed a sigh of relief slightly. Being able to fly is half the battle, after all, this is approaching the maximum payload of the envelope to take off. The deputy commander is Fang Chenggong, the new brigade commander who is working hard to establish his image and prestige. The influence left by the predecessor was too great, and he was under a lot of pressure.

"Six and six, six thousand, six thousand, sunrise, over." The officers on duty at various posts reported various information and data from time to time to provide the commander with a command basis, and Nie Jianfeng saw the latest meteorological information and immediately issued the latest instructions to the fighters.

Visibility is a big problem, and at an altitude of six thousand meters there is sunshine, which is more conducive to test flights.

Han Hongjun listened to the order to continue to climb the altitude, saying, "The climb rate is very low, it is estimated that it is not much faster than the H-6." ”

Li Zhan said, "The latest model of the H-6 also carries 15-ton bombs, and the current climb rate is much higher than that of the H-6." You're used to flying light-duty fighters, but you're not used to it all of a sudden. ”

"If it's in this state during the confrontation drill, it's a live target." Han Hongjun said with a smile.

At that time, when fighting with Chengda, half of the fuel of the J-16 had been consumed, and the overall weight was only more than 20 tons, and it had excellent fighting performance under the impetus of two 13-ton Taihang engines. It's a pity that I met a vector J-10B that can casually play with fallen leaves. With the blessing of the omnidirectional vector engine, the J-10B can even do some maneuvers that can only be completed by helicopters.

As far as close-range combat is concerned, I am afraid that in addition to the fourth-generation aircraft, the appropriate version of the J-10B has no opponents.

Li Zhan said, "Each model has its own focus on the direction of the task, and it cannot be simply compared. Do you see the North Reservoir Mountains, the throttle is deep and accelerates past. ”

"Understood."

"Tower, look at the latest weather over there, the fighter should have no power redundancy, I have to look at the situation for the next project, over." Li Zhan called the tower.

The phenomenon of pilots commanding the ground in reverse has reappeared, but the officers and men of the 101st Brigade have long been accustomed to it. As long as Captain Li is in the sky, the real commander is him.

Nie Jianfeng quickly checked the latest meteorological report of the Beiku Mountains and replied, "There is no obvious change in the meteorology of the Beiku Mountains, pay attention to the low clouds and fog in the mountainous areas, over." ”

"Six, six, six, understand, pay attention to low clouds and fog, over."

Since the maximum bomb load, it is natural to carry out low-altitude penetration test flights in mountainous areas, which is the most important skill for fighter-bombers, and it is based on this skill to eat, otherwise what is the difference with J-10 and J-11?

The view from the rear cabin is very good, and the view is more open than the front cabin at a higher position. Li Zhan could even see the sharp cone of the radome. The air data system of the J-16 is fully integrated into the avionics system, and various sensing instruments are distributed in various positions of the fuselage, so the traditional airspeed tube has no need to exist.

(When I was a child, I thought that the weapon of the J-7 was the long airspeed tube that pierced the Yankees' butt)

Li Zhan first saw the main peak of the Beiku towering in the distance, and then Han Hongjun also confirmed that he saw the most obvious landmark, and said, "I'll go over eight hundred, right?" ”

"When the throttle is turned on and the afterburner is pulled to 1,000, I calculate the acceleration time." Li Zhan took out a stopwatch.

The current airspeed is 500, and it is close to the speed of sound when it reaches 1,000. Li Zhan wanted to see how long it would take for the J-16 to pull from slow to subsonic speed with the maximum take-off weight and the maximum payload weight.

Han Hongjun immediately opened the afterburner and pushed the throttle lever to the end, and the two Taihang engines suddenly let out a heavy and powerful roar, and the tail nozzle opened to the maximum, spewing out a powerful air flow, disturbing the clouds behind him, forming an invisible air vortex.

For example, the fighter plane with a full load of heavy trucks rushed forward suddenly, and Li Zhan was surprised by the strong feeling of pushing his back, but then he didn't feel strange, driving afterburner, if there was no change, it could only mean that the engine was not good.

The second hardpoint on the inside of the right wing is a composite pylon, which is equipped with four simulated training missiles of the 250 kg class. In the sudden violent movement, the tremor of the fuselage made the screw, which had been less than half a turn, show signs of loosening.

When the airspeed reached 1,000 kilometers per hour, Han Hongjun turned off the afterburner, closed the throttle, and hovered in front of the sound barrier, and the airspeed of the affected fighters soon fell to more than 900. Li Zhan looked at the final time and felt very satisfied, it was very good to be able to reach this level in the state of maximum mounting.

"Tower, I'm going to go down to the height for a low-altitude penetration, over." Li Zhan glanced at the three-dimensional map on the display screen, and the small blue dot representing the landline had approached the east pass of the Beiku Mountain Range.

This is a low-altitude penetration route that eagles and falcons will open with their eyes closed - entering from the mountain pass on the east side of the mountain range, penetrating at a low altitude of more than 300 kilometers from northeast to southwest, and coming out from the mountain pass on the west side of the mountain range.

That is the "armed five-kilometer cross-country route" of the 101 brigade.

Han Hongjun was also confident, and the speed of the dive was fast and the angle was very large. Li Zhan didn't say anything, and he was afraid that his movements would be more violent. Otherwise, how can the extreme combat capability of the fighter be flown out? A real combat test flight is also a test flight, which in itself is fraught with more dangers.

The middle-aged man, who was originally steady and heavy, turned into a young man who hadn't done that for a long time, and when he saw a woman with big waves, a small leather skirt and black silk legs, he threw himself down.

"Well, that's kind of interesting." Li Zhan watched the earth surging towards him, and finally found some passion for flying.

Han Hongjun seemed to have received encouragement, pushed the throttle slightly, and the speed of the dive was faster, and said with a smile, "I wonder if the composite pylon we made ourselves can hold up?" ”

"I've tested it, no problem." Li Zhan said.

Nie Jianfeng interjected, "The composite pylon has been rigorously tested, and there is no strength problem. ”

"Understood." Han Hongjun grinned, and suddenly pulled the rod to resume level flight, and the altitude was exactly 1,200 meters high.

This is already more than 300 meters high.

Under the vigorous recovery of level flight, the screw of the composite pylons on the right wing, which had been less than half a turn, was loosened again, and under the action of vibration, it was loosened twice to expose a section of thread.

"Prepare to enter the mountain pass, repeat, prepare to enter the mountain pass and enter the ultra-low-altitude penetration test flight, finish." Li Zhan called the tower.

After entering the ultra-low-altitude penetration of the Beiku Mountain Valley, most of the flight sections could not be detected by ground radars, so the tower had no way to grasp the specific location of the fighters. However, now this situation has been changed to a certain extent, when the Beidou satellite transits, through the positioning of the Beiku tactical intelligence interactive system, the specific location of the fighter can be accurately obtained, and even a three-dimensional space map can be formed.

There is a reason for the selection of the maximum payload of ultra-low-altitude penetration defense at this time today, and the Beiku tactical intelligence interactive system can only play a role when the Beidou satellite is transiting.

"Unitary, six, six, the tactical intelligence system has seen you, and you can conduct an ultra-low-altitude penetration test flight as planned, over." After Nie Jianfeng confirmed that the tactical intelligence interaction system had identified and locked the No. 1616 J-16, he immediately replied.

"I understand, go down to the mountain, over." After Li Zhan finished speaking, Han Hongjun continued to push the rod down to the height, and it was very neat for the more than 30-ton fighter to descend in height!

It was a sudden resumption of level flight, and the sudden change of movement made the fighter plane have some squeaky sounds, which is a very normal sound, and it is strange if there is no sound. However, the screw came loose again, and half of it ran outside under the pressure of the force.

The composite pylons were not affected, and the one-ton simulated training bombs were hung safely.

The 1616 J-16 plunged headlong into the eastern pass of the Beiku Mountains, and in a moment entered the long and narrow Beiku Gorge. Han Hongjun's skills are not to be said, although they are not as sophisticated as Cheng Da's, but they can be ranked in the forefront of the Eagle Falcon Brigade.

He is very familiar with the use of the J-11B, and it is very easy to modify the J-16, and he quickly mastered the driving skills and stood out.

At this time, he made a sharp turn to avoid the mountain peak in front of him and entered the first "L-shaped" bend, and the simulated ammunition mounted on it looked as if it was about to graze the trees on the mountain, which was very thrilling. The Beiku Gorge is more than 300 kilometers long and has 81 bends of all sizes, which are called 81 difficulties by the pilots. Every pilot can fly the entire distance, but only a fraction of them can fly to a good standard.

Han Hongjun was one of those small group of pilots.

Challenging the 81st difficulty in the Beiku Gorge has long become the most difficult subject of the 101st Brigade, and the record holder is Li Zhan, who is undoubtedly the standard of excellence that he flew out, and the standard of excellence is determined by dropping by 20 percent according to the standard he flew out.

He's not your average.

Under the large overload maneuver, the screw is even looser, and it seems that only the dots are hooked up, and it looks like it is about to fall off but not falling off.

Han Hongjun, who was completely unaware of it, resumed level flight, and decisively turned on the afterburner to pull up the speed, and in front of him was a large straight road of more than ten kilometers, which was a good opportunity to accelerate and break through.

More than ten kilometers later, there was a big straight road, Han Hongjun skillfully manipulated the fighter plane to turn sharply to the left, and when he turned left suddenly, the screw finally broke free of the last bit of force and flew out, hitting the right engine compartment without any suspense, and penetrated the skin and pierced into it under the strong thrust.

Li Zhan keenly felt some unusual vibrations and frowned slightly. He quickly activated the automatic inspection system, "Something is wrong, activate the self-inspection system." ”

Han Hongjun had already seen the self-inspection system start working, frowned and said, "No abnormalities have been found." ”

"Check it out, feel safe." Li Zhan said.

When he sits in the rear cabin, he has the absolute control ability to surpass the front cabin like an instructor, and can directly take over control of the fighter at any time without the consent of the pilot in the front cabin. Under normal circumstances, weapon operators do not have this authority.

The advanced advantages of the fighter are reflected in the fact that the self-test system can complete the inspection of various systems in a very short time, mainly in terms of flight safety. Whether it is the J-7 or the J-11A, there is no such advanced thing, not to mention the Su-27.

Seeing that all systems were in a normal state, Han Hongjun breathed a sigh of relief and said, "All systems are normal. ”

"Hmm." Li Zhan is not very down-to-earth.

There was indeed a slight tremor just now, although it was very slight, so slight that Han Hongjun couldn't feel it at all, but Li Zhan was too familiar with the reaction of the fighter plane in various postures, just like a scene that had been watched for a long time suddenly came in and something unfamiliar, even if it was very inconspicuous, it would still attract attention.

However, the result of the self-test system is green, which is completely normal.

He will not let go of any suspiciousness.

"You pay attention, I'll check again." Li Zhan said in a deep voice.

Han Hongjun was a little unimpressed, and said, "Understood." ”

Li Zhan took off his flying helmet and listened attentively, there were faintly some very slight strange sounds coming from behind, and if he listened carefully, it seemed to come from the fuselage. He was almost immortal, and in this case he could hear a small screw swaying slightly in the engine compartment.

However, the results of the second inspection of the self-inspection system still showed that it was normal, and the state of the aircraft was also normal.

Seeing that he had already penetrated dozens of kilometers at an ultra-low altitude, the uneasiness in Li Zhan's heart became stronger and stronger.

He decisively called the tower, "Tower, I don't feel that the plane is quite right, and I ask to return." ”

Abort the mission?

Everyone in the tower looked at each other, what was the situation?

Nie Jianfeng even suspected that he had misheard, and subconsciously asked, "Six, six, please repeat." ”

Li Zhan became even more uneasy in his heart, and said decisively, "Tower, I'm going to sail back." ”

"You mean abort the mission and return home? Six, six, please explain the situation, over. Nie Jianfeng was surprised and looked at Fang Chenghe with an inquiring look.

After preparing for such a long time and using so many resources, the test flight mission was aborted if it was aborted, but the problem is that it is difficult to understand that it is suddenly necessary to do so when the state is normal. Although everyone knows that Li Zhan will not make such a decision at will, there is at least a good reason!

Li Zhan is a typical example of resolutely completing the task in the face of great difficulties, when the plane lost one of its wings, he did not give up and took a huge risk to make a forced landing, what happened today?

"What the hell happened?" Fang Chenghe took the microphone and asked.

Li Zhan replied, "I feel that the plane is not quite right, I have to return to the plane, please approve it, over." ”

Doesn't feel right?

This is unconvincing, if it feels useful, what do you want the avionics system to do?

"Six, everything is in normal condition of the plane, have you found any other problems?" Fang Chenghe once again confirmed that the data on the real-time status terminal of the fighter connected to the aircraft perception system through the tactical intelligence interaction system was normal, and asked again.

The uneasiness in his heart became more and more intense, Li Zhan didn't care, and said, "Xiao Han, I took over the plane and the tower, I feel very uneasy, I have returned, over." ”

He exercised absolute control over the captain, and the ground could no longer force him to continue the test flight mission.

Everyone looked at each other, what happened to Captain Li today, this is not his style at all, is the myth shattered?

Even Han Hongjun was stunned, and repeatedly checked the data of the self-test system, which was so normal that it couldn't be normal anymore.

However, the first thing Li Zhan did when he operated the fighter was to throw away all the mounts, and then flap his wings and return to the Beiku combat training base in a straight line......
