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 requirement for the Falcon Brigade is to have all Cobra members.

But except for Nie Jianfeng and Tang Leilei, no one else has trained in this subject. You don’t have the conditions to train the J-7. Of course, the ultra-low-altitude Cobra maneuver that Li Zhan flew out in an emergency during the 4-1 actual combat is not popular.

The possibility. Even if Li Zhan tries it again, he may not be able to fly out.

After Nie Jianfeng and Tang Leilei completed the Su-27sk modification in the Second Division, they completed all the aerobatic maneuvers and flew the Cobra very skillfully. Naturally, they were the instructors.

Of course, Li Zhan wanted to fly solo. He joined the army two years later than Nie Jianfeng, but his flying hours exceeded Nie Jianfeng, which shows how brutal 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 first half was painted in desert and the other half was painted in gray low-visibility paint, which looked very much like a chicken.

A big rooster with bright hair and a high 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 flying through the field several times, the tower issued an order to start training.

The so-called Cobra maneuver simply means that the fighter plane flies level and then suddenly and quickly raises the nose of the aircraft to 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 push the push rod to press the nose and return to level flight.

The main implementation conditions are altitude and speed. Generally, it is required to be carried out at an altitude of 3,000 meters to 11,000 meters, and the surface speed for level flight is between 300 and 400 kilometers per hour. It is required to be carried out at an altitude of 1,000 meters and below.

Cobra maneuvers require rigorous training.

Last time, Li Zhan made a suspected Cobra maneuver at an ultra-low altitude of more than ten meters and was still flying the J-7e. It can only be called a miracle. It is theoretically untenable.

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 the Su-27 knows that if the direct link mode is used, the attitude of the fighter is very difficult to control, especially the trimming problem. The mid-air disintegration that occurred during the development was due to the extreme pressure of the pilot's lever when using the mechanical control system for longitudinal control.

It is easy to cause the aircraft to be overloaded and cause comminuted fractures in an instant. Later, a 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.

Pull the joystick to the rear limit position in three seconds, so that the nose of the plane can be raised to 110 or 120 degrees in a short period of time, and the angle of attack of the plane is about 90 degrees. When the nose of the plane is downward,

, 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: for level flight, 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 to use the entire lifting surface of the aircraft as a huge speed brake to achieve the purpose of rapid deceleration?

Through such maneuvers, you can achieve position exchange with the enemy in the rear hemisphere. If you are being chased, if you suddenly make such a move, 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 doing such a maneuver 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, and without speed, it cannot

energy.

Aren’t they just living targets?

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

Li Zhan is a staunch supporter of the speed runoff. He would not feel safe if he did not allow himself to be as close to the ultimate speed as possible. His views on the Cobra maneuver are based on this theory, so it is difficult to define who he is.

Supporters of the theory that Cobra is useful are also supporters of the theory that Cobra is useless.

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 3,000 meters. The airspeed was maintained at a precise 425 kilometers per hour, and he entered the sky above the field station at this speed.

"I'm starting!"

After giving the action command, Li Zhan quickly disconnected the fly-by-wire flight control and the angle of attack limiter, and almost simultaneously pulled the stick back to the end. The No. 01 Su-27sk heavy-duty twin-engine dual-vertical tail air control in double-color painting in level flight

Like a wild horse whose reins were suddenly tightened, the fighter jet suddenly raised its head and pointed directly at the sky. Under the action of inertia and forward kinetic energy, the tail of the aircraft continued to move forward, and the angle of the nose of the aircraft quickly reached 120.

Spend.

Not as skilled as a novice.

Then it stalled.

The double-color Su-27sk heavy-duty twin-engine and twin-vertical tail air superiority fighter No. 01 rolled down and fell.

"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 line.

The risk of training Cobra maneuvers is mainly reflected in stalling. The reason why this flight maneuver is considered a difficult maneuver in the world is precisely because of the high risk. The entire process requires the pilot's control actions and timing to 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! Turn on 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 of the early Flanker series fighters is not the so-called rickets, but its extremely complex composite control system. As mentioned earlier, this aircraft uses a combination of longitudinal electric wire and transverse mechanical transmission as the control system. The structure is not only huge 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 surprising that a Cobra maneuver stalls and spins. Recovery from tail spins is a must-have skill for every pilot, just like cockpit blind maneuvers. Air Force pilots also have to memorize dozens or hundreds of emergency response plans.

When it comes to control actions, 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 commander in the tower, was not very worried. When he first learned about it, he stalled and tail-spinned twice and successfully recovered.

It is the norm. Of course, the su-27sk is much easier to modify than the J-7.

But Li Zhan reported that the flight control failed, which was very fatal. The su-27sk did not have a mechanical backup control system, and the failure of the longitudinal fly-by-wire flight control system meant that the pilot lost control of the fighter. Not to mention that it was stalling and rolling and falling.

Even in level flight at high altitude, this is a very fatal failure.

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 try to light up when you're ready to give up, they light up suddenly.

.

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 J-7e at the time, had its nose landing gear stuck. After the emergency landing, the maintenance inspection found no damage.

It is normal for Lou Yiwang to drop a hammer. This is difficult to explain from a conventional perspective.

At this time, the double-color Su-27sk heavy-duty twin-engine dual-vertical tail air superiority fighter No. 01 was in a state where its wings were rolling, swinging, 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 has 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 safe height for training 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-tail air superiority fighter No. 01 only has a few hundred lifespan left. A real warrior should die on the battlefield. It is also an honor for him to be killed by Li Zhan in the training ground.

.

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 altitudes of more than ten meters. He is a man who can complete 301 actions in 70 seconds. He is more than 1,000 meters high enough for him to contribute vigorously to the construction of a powerful People's Air Force and the preservation of military property.

A handful of strength.

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

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

"The brigade commander is not here, but I am here. 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 regimental level or above. The 101 brigade team has not yet been fully formed, and there are relatively few regimental-level leaders, which is simply not enough. Therefore, this veteran who is showing off his second youth

The political commissar personally went into battle and sat at the tower.

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

What kind of plot 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."
