Great Power Fighting Falcon

Cobra maneuver is not required to learn aerobatic maneuvers. The troops can comprehensively consider whether to conduct training on this maneuver, or which people should perform it and which ones should not.

There is controversy within the military about the actual combat effectiveness of the Cobra maneuver, but the general view is that mastering the Cobra maneuver is more important than mastering superior flying technology.

If you can fly a cobra, it means your skills have reached a new level.

Naturally, the higher the flying skills, the better.

The requirements for the Falcon Brigade are all Cobras.

But except for Nie Jianfeng and Tang Leilei, no one else has ever trained in this subject. Even if you want to train the J-7, there is no condition. Of course, there is no possibility that the ultra-low-altitude Cobra maneuver that Li Zhan flew out during the emergency situation in the 4-1 actual combat will be popularized. Even if Li Zhan is asked to do it again, he may not be able to fly out.

Nie Jianfeng and Tang Leilei completed all aerobatic maneuvers after the Second Division completed the SU-27SK modification, and the Cobra flew very skillfully. Naturally, they were the two instructors.

Of course, Li Zhan wants to fly solo. He joined the army two years later than Nie Jianfeng, but his flying hours exceeded Nie Jianfeng, which shows how cruel this man's flying experience was.

At 14:00 in the afternoon, the No. 01 SU-27SK heavy-duty twin-engine, twin-vertical tail air superiority fighter with dual color matching took off. The front half is painted in desert and the other half is painted in gray low-visibility paint. It looks like a big rooster with brightly colored hair and a raised head.

Li Zhan had nothing mounted on him, and the fuel in the aircraft was half full. The fighter plane was in the best condition for maneuvering. After several flights through the field, the tower issued the order to start training.

The so-called Cobra maneuver simply means that the fighter plane flies levelly and then suddenly and quickly raises the nose of the aircraft at an elevation angle between 110 and 120 degrees, forming a brief level flight state with the nose tilted back and the butt forward. In this state, the fighter's speed will instantly drop to close to zero. From a distance, the fighter looks like it is reining in a cliff. Then the push rod presses the machine head back to the level flight state.

The main implementation conditions are altitude and speed. Generally, it is required to be implemented at an altitude of 3,000 to 11,000 meters, and the surface speed for level flight is between 300 and 400 kilometers per hour. Strict training is required to perform Cobra maneuvers at an altitude of one thousand meters and below.

Last time, Li Zhan made a suspected Cobra maneuver at an ultra-low altitude of more than ten meters and flew the J-7E by mistake. It can only be called a miracle. Theoretically this is not true.

The specific driving essentials are very simple to express.

The SU-27SK fighter's longitudinal telex flight has two modes in the air, namely "flight" and "direct link". To understand it from another angle, the former mode is actually an automatic trimming mode, while the latter requires manual trimming.

Anyone who has flown a SU-27 knows that if the direct link mode is used, the attitude of the fighter is very difficult to control, especially the trimming issue. The mid-air disintegration that occurred during the development was due to the fact that when the mechanical control system was used for longitudinal control, the pilot's pressing and pulling of the lever could easily cause the aircraft to explode and cause comminuted fractures due to overload. Later, the longitudinal telex was installed to solve this catastrophic problem.

Maintaining level flight at the specified surface speed, the pilot manually switches the "flight" mode to the "direct link" mode, which means to disconnect the fly-by-wire flight control and use manual control, and then disconnect the angle of attack limiter. In three seconds, pull the joystick to the rear limit position to raise the nose of the aircraft to 110 or 120 degrees in a short time, and the aircraft's angle of attack is about 90 degrees. When the nose of the aircraft is down, push the stick to the neutral position to restore the aircraft to level flight, turn on the "flight" mode and angle of attack limiter, and restore normal control of the fly-by-wire system.

To sum it up in one sentence: When flying level, cut off the flight control angle of attack, pull the stick, press the stick, and connect the flight control angle of attack.

The whole theory is also very easy to understand.

It is generally believed that the tactical significance of this maneuver is to enable the aircraft to reduce its speed to a minimum in a very short time. Isn't it just using the entire lift surface of the aircraft as a huge speed brake to achieve rapid deceleration?

Through such maneuvers, the position exchange with the enemy in the rear hemisphere is achieved. If you make such a sudden move when being pursued, the pursuing enemy will rush in front of you, and the advantageous side in the tactical position will change hands.

However, some people believe that performing such maneuvers in an air combat will make oneself a living target. This view is also well-founded. Because in this action state, the fighter plane has almost no speed at all. Without speed, there is no energy.

Isn't it just a living target?

In fact, there are no ineffective or wrong tactical actions, only wrong pilots using them.

Li Zhan is a staunch supporter of speed in the final round. He doesn't feel safe unless he is as close to the ultimate speed as possible. His views on Cobra's maneuvers are based on this theory, so it is difficult to define whether he is a supporter of the theory that Cobra is useful or a supporter of Cobra's uselessness.

From a macro perspective, no matter what fighting moves or tactics you use, as long as you are the one who survives in the end, you are the king of the sky.

Li Zhan once again took the route through the field, but the route was at a training altitude of three thousand meters. The airspeed was maintained at exactly 425 kilometers per hour as it entered the airspace above the station.

"I'm starting!"

After giving the action command, Li Zhan quickly disconnected the fly-by-wire flight control and angle of attack limiter, and almost simultaneously pulled the stick back to the end. The No. 01 SU-27SK heavy-duty twin-engine twin-vertical tail air superiority fighter with double-color matching paint in level flight is like a wild horse whose reins were suddenly tightened. It suddenly raised its head and pointed directly at the sky. Under the influence of inertia and forward kinetic energy, Down, the tail of the plane continued to move forward, and the angle of the nose of the plane quickly reached 120 degrees.

So skillful that he doesn't look like a novice.

Then stalled.

The double-coloured No. 01 SU-27SK heavy-duty twin-engine, twin-vertical tail air superiority fighter rolled and fell down.

"Beep beep beep beep beep..."

Continuous sirens filled the cockpit. Without Li Zhan's need to report, the tower had already heard these sirens from the radio that was still on the phone.

The risk of training Cobra maneuvers is mainly reflected in stalling. The reason why this flight maneuver is considered a world-wide difficult maneuver is precisely because of its high risk. The entire process requires that the pilot's control actions and timing must be accurate to within 0.5 seconds. On the other hand, it is considered that it is not possible to be popularized because of its high difficulty. If it cannot be popularized, it will naturally lose its tactical significance.

"I'm stalled! Engage flight control!"

Li Zhan remained calm and quickly reconnected the fly-by-wire flight control and angle of attack limiter. Then he found that the angle of attack limiter was turned on, but the fly-by-wire flight control did not respond.

"The fly-by-wire flight control failed!"

Li Zhan quickly reported and at the same time continued to give instructions to the fighter plane through the joystick. The fighter plane responded, but the response was extremely weak. It seemed that there was an invisible force pulling it to maintain the current out-of-control state.

"Turn on the flight control again!" Li Zhan repeated the operation.

Still no response.

The common problem with the early Flanker series of fighters was not the so-called rickets, but their extremely complex complex control systems. As mentioned earlier, this aircraft uses a combination of longitudinal electric transmission and transverse mechanical transmission as the control system. The structure is not only large but also complex. Once the longitudinal fly-by-wire flight control fails, almost no one can keep the fighter plane in level flight. The fighter plane will fly forward in wavy lines, its nose will rise and dive, and it will stall if it is not careful.

It's not worth making a fuss about the Cobra maneuvering, stalling and spinning. Tail spin recovery is a must-have skill for every pilot, just like blind cockpit maneuvers. Air Force pilots also need to memorize dozens or hundreds of control actions to deal with dangerous situations. Don't think that the lever fee is so easy to get.

Therefore, after learning that the No. 01 SU-27SK heavy-duty twin-engine, twin-vertical tail air superiority fighter had stalled, Nie Jianfeng, who served as the main commander at the tower, was not very worried. When he first learned about it, he stalled and tail-spinned twice and successfully recovered. It's the norm. The SU-27SK is certainly much easier to modify than the J-7.

But Li Zhan reported that the flight control failed, which was very fatal. The SU-27SK does not have a mechanical backup control system, and the failure of the longitudinal fly-by-wire flight control system means that the pilot lost control of the fighter. Not to mention stalling, rolling and falling, this is a very fatal failure even in high-altitude level flight.

Maybe it's not a mechanical failure, maybe it's just because the fighter plane is in a certain state at a certain point and it malfunctions. Like some lighters, they obviously have a lot of oil but they just can't light up. But of course, when you're ready to give up, you try to light them up, and they suddenly light up. .

Modern fighter aircraft are the result of huge and complex system engineering, and many faults are difficult to explain from a technical perspective. For example, the No. 037 J-7EGG, which was still called the J-7E at the time, had its nose landing gear stuck. After the emergency landing, the maintenance department inspected and found no damage. After the landing, it was normal for the aircraft to hit the ground with a hammer. This is difficult to explain from a conventional perspective.

At this time, the dual-color SU-27SK heavy-duty twin-engine dual-vertical tail air superiority fighter No. 01 was in a state where its wings were rolling, swaying, and dancing wildly. The fighter did not enter a tail spin state, but it was like a paratrooper whose parachute failed to open...

Li Zhan had no speed at all.

When he pulled up the nose of the Cobra, the airspeed dropped at a rate of about one hundred and eighty kilometers per second. In other words, when the fighter's butt moved forward, Li Zhan basically lost speed.

But he still has height.

Li Zhan still needs time to maneuver the Cobra to the minimum training safety height of three thousand meters.

He kept repeating the operation of turning on the fly-by-wire flight control, and at the same time continued to issue movement instructions to the fighter plane through the joystick, trying to regain control of the runaway wild horse.

"Dongyao, prepare to parachute, you don't have much height!" Nie Jianfeng gave the order decisively.

The double-color SU-27SK heavy-duty twin-engine twin-vertical tail air superiority fighter No. 01 only has a few hundred hours of life left. A real warrior should die on the battlefield. It is an honor for him to be killed by Li Zhan on the training ground. of.

Li Zhan said, "I still have more than a thousand meters to go, so don't worry! I have plenty of time!"

He is a man who has done ultra-low-altitude Cobras of more than ten meters. He is a man who can complete 301 actions in seventy seconds. He is more than a thousand meters high enough for him to work hard to build a strong People's Air Force and protect military property. Make a contribution.

"Don't show off! You know Su Liangqi's flaws!" Nie Jianfeng reminded seriously.

Li Zhan replied in a deep voice, "Understood. If the situation cannot be saved at the lowest skydiving height, I will parachute. Is the brigade commander nearby?"

"The brigade commander is not here but I am the political commissar." Bao Guanhua picked up the microphone and said.

Bao Guanhua is the deputy commander, and high-risk maneuvers require the presence of leaders at the deputy regiment level or above. The team of the 101st Brigade has not yet been fully formed, and there are relatively few regimental-level leaders, which is simply not enough. So the old political commissar, who was glowing with his second youth, went to the battle in person to sit on the tower.

Li Zhan said, "Report to the political commissar, I request to shut down the car and start it again, over!"

What is this?

Bao Guanhua didn't understand.

It takes about ten seconds to reach a height of more than a thousand meters.

Nie Jianfeng didn't bother to explain to Bao Guanhua. He said urgently to Li Zhan, "Dong Yao! Guan Ding's recovery is not universal! You have to be careful!"

Li Zhan made up his mind, "There is no other way, I will give it a try."

Unless there is an engine failure, such as a fire, it is not easy to shut down the engine in the air. Because driving in the air is not successful every time. Fighter aircraft have APU, auxiliary power system, also called auxiliary power system. Its main function is to start the engine on its own power, especially in the air. When fighter planes are on the ground, ground power supply vehicles are usually used to help the engines start, because this is the most reliable and saves the fighter's own power supply energy.

Why can’t air driving ensure success every time?

Whether it is a turbojet aircraft engine or a turbofan aircraft engine, it needs to burn a large amount of air when working. Just look at the air inlet of a fighter jet that is not much smaller than the body of the aircraft. This requires that the fighter aircraft must be at a specified altitude and in a suitable wind direction before it can drive in the air. In other words, the attitude of the fighter aircraft must meet the requirements.

The current posture of the double-color SU-27SK heavy-duty twin-engine twin-vertical tail air superiority fighter No. 01 obviously does not meet the requirements at all.

The reason why Li Zhan applied to the tower was precisely because the aircraft's posture did not meet the requirements for aerial driving. In this case, he could not take the initiative to shut down the aircraft.

Power is everything, and a fighter plane that loses power is just a brick.

If the car cannot be restarted after voluntarily shutting it down, Li Zhan must admit responsibility.

This is the real reason why Nie Jianfeng was so excited to persuade him to be cautious. Originally, it was nothing to do with me. As long as the operations were in compliance with the regulations, the plane crashed and it crashed. Anyway, it didn’t take long to survive, but you are very important. The backbone of the 101st Brigade cannot have anything wrong. Now you have to try a new method of handling things that don't comply with the regulations. Isn't this asking for your own death?

The people in charge of the investigation by the Military Region Air Force don't care how many first-class merits you have, and whoever is responsible will be held responsible.

"Old Li! No need!" Nie Jianfeng violated radio communication regulations and called in plain language.

Li Zhan's attention is on the status of the fighter. He is experiencing the changes in the posture of the dual-color No. 01 SU-27SK heavy-duty twin-engine dual-vertical tail air superiority fighter. Three or five overloads are like a snack for him. Therefore, his consciousness is very clear and his heartbeat is very stable. The nerve endings all over his body seem to be connected and integrated with the double-color No. 01 SU-27SK heavy-duty twin-engine dual-vertical tail air superiority fighter. He who loves her dreams of her dreams. She is grieving her sorrow. There is no wind and rain to hide, but there is no ups and downs. We don’t have to walk. Holding hands, we will walk together in the next life...

Testing whether turning off the air in the air can help recover from stall or stall spin conditions is now an extremely rare opportunity, and Li Zhan will never miss it. If you don’t want to take the risk of flying a fighter jet, just go and fly the civil aviation Dabo Kong.

He caught the pattern and quickly turned off two rounds. At a certain moment before the fighter's posture was about to enter a very brief suitable posture, he quickly turned on two rounds. He accurately calculated the delay time and the time for the fighter aircraft's attitude to change to the appropriate state.

The two AL-31F aero engines restarted shortly after shutting down, and Li Zhan made a surprising move - turning the afterburner throttle lever to the end.

The No. 01 double-color SU-27SK heavy-duty twin-engine, twin-vertical tail air superiority fighter jet, which dropped like a headless fly with its nose down, suddenly accelerated and dived toward the ground.

Li Zhan turned on the flight control system again, and this time he got green.

"Damn it, if anything goes wrong after landing, I'll burn you bastard Su Liangqi immediately! Tower! I'm normal!" Li Zhan cursed angrily and raised the lever.

The double-colored SU-27SK heavy-duty twin-engine twin-vertical tail air superiority fighter No. 01 was like a very docile little sheep. It pulled up obediently and resumed level flight. At this time, it was still three to four hundred meters above the ground.

Everyone in the tower breathed a sigh of relief.

Li Zhan asked for instructions, "Tower, I have checked repeatedly and there is no problem with all systems. Can we continue training, or should we land for inspection first? Over."

Even Nie Jianfeng was speechless. Even after this, you still want to continue training.

"Dongyao, I order you to return immediately, over!"

"Dongyao received it and will return immediately. It's over..."
