Chapter 491: Cobra Maneuver Can Fire Extinguish!
"Test Six! Get ready to abandon your machine! ”
The commander on duty had given such an order again, and he could not remember how many times he had given the same order. When the J-10B, which rushed to support, reported that an open flame had ignited at the junction of the belly of the No. 1616 J-16 and the engine compartment, the commander on duty was basically certain that the plane could not be saved.
The catastrophe of a fuel tank ignition is devastating, and there is no precedent for a successful forced landing – planes usually explode and disintegrate in the air, and the pilot's body is hard to find.
If you had to die, no one would choose this way to die.
What's even more frightening is that the explosion caused by a fuel tank fire is usually very short, from a few seconds to a few minutes, and it is impossible to tell when it will explode!
The crew has only a few seconds to decide whether to abandon the plane and jump or risk an alternate landing.
The pilot in the front cabin had the absolute right to decide, and only two seconds later, Li Zhan slammed the lever to quickly descend in altitude, and on the three-dimensional radar map, the 1616 J-16 was diving down to the sea. He didn't have time to report the situation to the southeast district governor, and at this time he had to brace up 120,000 spirits to deal with the matter.
"Is he going to make a crash landing on the water? Fighter jets can't do it, right? The controller of the southeast district management said in surprise.
The duty officer quickly reported the situation to the air force command post, "He is going to make a forced landing on the sea, and we will immediately activate the sea search and rescue plan, but the actions of your troops may be faster and complete." ”
"We saw it here, thank you!"
The duty commander did not know how to feel, because the planes of the army had encountered serious problems, but in the hearts of those soldiers, even if the plane crashed, they did not want to cause trouble to the localities. Those who serve as soldiers regard themselves as the last support of the common people, and never think of relying on the relevant local departments to complete their tasks.
Is a forced landing on the surface possible?
Chen Fei was also thinking about this problem, and he had indeed received training in this area when he was trained, but there was no big difference between a fighter plane's forced landing on the surface of the water and falling into the water. The aerodynamic layout of fighter jets makes it impossible for them to use the surface of the water as a runway like ordinary transport aircraft and civil airliners.
At present, many passenger aircraft, including some military transport aircraft, are designed to take into account the situation of forced landing on the surface under abnormal conditions, so there will be some targeted designs. For example, if conditions permit, the buoyancy of the aircraft can be increased by fine-tuning the shape, and so on.
Fighters do not have this consideration - the pilot has ejection seats and can parachute out of the dangerous fighter.
The officers on duty in Fu Zhi knew why Li Zhan made a forced landing on the water. The J-16 No. 1616 is a very precious prototype, and it can be said that this aircraft is full of treasures, which directly affects the standard of production models. And this time the night flight because of the influence of various factors, the 1616 J-16 has a very rich experience, especially the two confrontations with the two main models of the first are the most in-depth exchanges in recent years, which is too important for the preparation and training of the troops.
Therefore, Li Zhan had to make a forced landing on the surface to keep the fighters.
On the other hand, it is because of the high flag airport. It is a very large aviation hub, which can rank among the top 15 in the country, with hundreds of flights taking off and landing every day, and any impact may cause tens of thousands of passengers to be stranded, which will seriously affect the normal production and life of the locality.
Li Zhan could not land a plane with a high probability of an explosion at Gaoqi Airport.
When the commander on duty saw the No. 1616 J-16 descending to an altitude of only 20 meters above the sea surface and accelerating to the coastline, he thought that he had completely guessed what Li Zhan was going to do - to be as close to the coastline as possible, so that it would be convenient for both rescue and salvage of the fighters.
However, when he thought that Li Zhan should speed up and fly towards the coastline, he found that the speed of the J-16 No. 1616 suddenly slowed down.
He hurriedly called Li Zhan, "Test Six, your speed is decreasing, what's the situation?" ”
"I'm going to put out the fire, Fu Zhi."
When Li Zhan finished saying this, he had already firmly controlled the fighter plane and continued to slowly descend in altitude.
At this time, the current sea state in the sea area is level four, and the wave height is two or three meters.
He wants to use the waves to extinguish the open flame at the junction between the belly and the engine compartment!
Who would have thought that his purpose would be like this?
"Lao Li! The consequences of water ingress into the air intake will be even more serious! Chen Fei reminded loudly.
The appearance of the J-16 and J-11 is generally the same, with only a few slight differences, and the two air intakes are deployed under the belly, which is the lowest position except for the landing gear. If there is water in the air intake, the situation is even more serious.
Li Zhan said, "I know, but I have to try." Have you ever played an ultra-low-altitude Cobra maneuver, I often play, the first time was in Beiku, driving the old plane of No. 037 J-7, and I was forced to do a highly suspected Cobra maneuver at a height of more than ten meters from the ground. The second time was the No. 01 Su 27, which entered at a speed of more than 600 kilometers per hour, and later the plane fell apart after a successful forced landing on the highway. My experience tells me that the standard Cobra maneuver of the Su-27 has a lot of redundancy, and as long as you master the speed of the entry, you can do this maneuver at a lower altitude. ”
Do a cobra maneuver at a height of more than ten meters above the sea surface? Crazy!
However, Chen Fei's eyes soon lit up, and he had to admit that this was a very creative approach, but it required a huge risk!
Li Zhan said, "Lao Chen, put your hand on the ejection lever, when you hear me say that you have to pull the lever to bounce as soon as you jump, I don't have any extra hands!" ”
"Understood!" Chen Fei touched the ejection lever and became highly nervous.
I don't know when the moonlight began to come out, the sky was washed and cleaned, and there was not a single cloud, and the moonlight starlight came down unhindered and sprinkled on the sea, flickering with the waves, like a bunch of luminous powder was sprinkled on the sea. The outline of the coastline can be seen not far away, and it will be a good ultra-low-altitude flight in a different state.
Dai Mengmin descended to fly on Li Zhan's left flank, he had just seen the 1616 J-16 neatly drop the altitude to more than ten meters above the sea, and when he arrived at his side, he found that it would take more time to do this. He was shocked by Li Zhan's flying skills and worried about Li Zhan.
No. 1616 J-16 dragged a tongue of fire against the sea and flew fast, and the picture looked very beautiful!
Can it be successful?
Li Zhan quickly eliminated other interference, regardless of any calls from the radio and the Southeast District of Civil Aviation, he slightly adjusted his breathing like a sniper before shooting.
The speed of the watch is 280 kilometers per hour, which is a little lower, and he slowly pushes the throttle stick to raise it, and the altimeter shows that the sea height is 30 meters, but he knows that except for the 3 meters of wave height on the sea surface, this height is just right, and all the flaps are in the right position. Thankfully, the rudder was back to normal, otherwise he really couldn't help it.
The speed of the watch showed 350 kilometers per hour, and Li Zhan shouted, "It's coming!" ”
Disconnected the elevation limiter, suddenly pulled the rod back to the bottom, the fighter's butt sank suddenly, the nose of the plane slammed up, the attitude of the fighter "turned into a fist", the airspeed dropped suddenly, the number of the speedometer was falling rapidly, when Li Zhan saw that the number was about to fall to "0", he quickly pushed the rod, and at the same time the throttle stick pushed to the end, the nose of the machine fell sharply as if it had been slapped in the face, and quickly connected the elevation limiter, and the two shots made a huge hissing sound, The fighter continued to fly forward at an elevation angle of 70 degrees for hundreds of meters before slowly returning to Li Zhan's control.
Dai Mengmin, who was in charge of observation on the left flank, was stupid - just when he saw that the 1616 J-16 made a cobra maneuver at a height of more than 30 meters above the sea surface!
The place where the fire caught fire at the back of the belly of the plane hit the surging waves, and the open flames were extinguished without any suspense. The butt of the 1616 J-16 slid over the waves, the tail of the plane subconsciously cocked upwards due to the resistance, and the nose of the plane pressed down uncontrollably.
It's a genius manipulation!
However, Dai Mengmin was surprised that the fire did not catch fire again. It was clear from previous reports that it was an open flame caused by the fuel leaking from the tank being ignited by the vent tail flame. The problem is that seawater doesn't seem to play much of a role against burning jet fuel.
But the fact in front of us is that the open flame did not rekindle.
When Dai Mengming was surprised, Li Zhan hurriedly asked him: "Raptors No. 1!" Is the fire out? ”
"Extinguished! Extinguished! I can't see any open flames! Dai Mengming hurriedly replied.
Li Zhan finally breathed a sigh of relief, "Understand, the Southeast District Administration, this is the sixth military aviation, the fire is under control, I want to land immediately, please tell me the specific location of the airport!" Complete! ”
"Military Aviation Rank Six! The airport is right in front of you, please contact the tower directly, and you're done! "The Southeast District Management did not know how the No. 16 military aviation plane solved the fire problem, they were very professional and immediately took the most simple and direct method.
Skipping the approach desk and contacting the tower directly streamlines the process.
Li Zhan quickly called Gaoqi Airport, "Gaoqi Tower, I am the sixth military aviation, please tell me the runway number, thank you!" ”
"Military Aviation Unitary Sixth, Runway 27, you can go directly to Runway 27! All other runways are open to you, and you're done! The Gaoqi Airport Tower replied quickly.
Runway 27 is the most suitable runway, and the J-16 No. 1616 does not need to steer maneuvering, as long as it flies directly over the nose of the aircraft to aim at the runway.
Li Zhan replied, "The military aviation understands that runway 27!" ”
At this moment, Chen Fei noticed that Li Zhan had turned off the left firing, and at this time, the fighter was only flying from the right firing. The reason why the open flame at the oil tank leak did not rekindle was found, and Li Zhan cut off the oil supply to the left engine. I have to say that their luck is very good, the place where the oil leak is the fuel supply pipe between the fuel tank and the left engine, and the left hair is closed to cut off the oil supply and solve the problem of fuel leakage. If it is a leak in the main oil supply circuit, Li Zhan's operations are meaningless, so luck is on their side.
Chen Fei didn't notice when Li Zhan turned off his left hair and cut off the oil supply to his left hair, which showed that Li Zhan had already thought about it before taking such an adventure, and every step and every manipulation action was extremely accurate. When the sea water extinguishes the external open fire, and at the same time, the elevation angle of the fighter must return to the envelope, and these conditions can be met to close the left engine and cut off the fuel supply, otherwise the fighter will stall and fall into the sea.
The timing is very, very important, and Li Zhan did it very, very accurately, threading the needle.
When you need to make some kind of manipulation action, there is no slightest drag, and the buffer pause that needs to be reserved between the manipulation actions is also very neat, and the whole process is like presetting all the parameters in advance, and then the intelligent robot completes all this. The most frightening thing is that it seems that the waves are listening to Li Zhan's command, and they have not played a bad role at all.
This time on the night flight, Chen Fei felt that his concept had been refreshed, and he deeply understood the profound meaning of the words and aphorisms such as "there are people outside the world" and "genius pilots".
At the same time, he inevitably had the idea that he was redundant in this actual combat test flight. What else can you do besides preparing to pull the ejection lever? He couldn't keep up with Li Zhan's pace, and even the sense of happiness for the rest of his life after the catastrophe couldn't withstand the sense of loss.
Li Zhan didn't know what Chen Fei was thinking at this time, unless the fighter plane stopped steadily on the runway, his string would always be tight.
Gaoqi Airport is a large airport, several square kilometers in size, and Li Zhan easily saw the runway lights that were very conspicuous in the darkness. Only the 1616 J-16 that was working on the right maintained a speed approach of 240 kilometers per hour, and after aiming at the runway, Li Zhan lowered the landing gear.
The front and rear landing gears were put down smoothly, Chen Fei did not forget his duties, and confirmed with Li Zhan, "The landing gear is down." ”
"Confirm." Li Zhan replied.
Chen Fei reported the height he saw, "One hundred and fifty meters." ”
"Confirm."
The data displayed on the instrument panel of the front and rear cabins is exactly the same, and Chen Fei is ready to take over the control of the aircraft at any time, and once the pilot in the front cabin suddenly becomes incapacitated, the pilot in the rear cabin can immediately take over the aircraft.
In the tower of Gaoqi Airport, the military acting director, accompanied by the person in charge of the airport, left briskly and rushed to Runway 27 in a commuter vehicle. The tower commander stared nervously at the lights of the No. 16 military aviation plane, and she was surprised to find that there was only one tail flame. She quickly looked at the situation reported by the troops, and it was a twin-engine fighter that landed on the field, but now there was only a tail flame.
"Attention units! There is only one engine working in the military aviation unit, he is a single engine landing, please be prepared! The tower commander quickly informed all units of the situation, especially the emergency rescue unit.
The No. 16 military aviation aircraft dragged an orange tail flame to the ground slowly, the nose was slightly raised, and after entering the range of lights, everyone saw that it was a very domineering fighter with a somewhat olecratic beak in the nose, which was completely different from the powerful roar of the civil engine, which made people feel inexplicably excited.
As one of the few large airports with a department such as the Support Frontline Office (Support Front Office), Gaoqi Airport has finally made a modest contribution to the People's Air Force.
With the front and rear landing gear tires firmly crushing on the 3,200-meter-long first runway, the No. 16 plane of the Military Aviation successfully diverted to the high-flag airport. The ground support detachment, the emergency rescue detachment, and the small detachment of the military representative office rushed up and pounced on them......
PS: There is a branch office in the local government agencies in Fujian, and there should still be it now, which is to support the front-line office, a little-known unit that sounds like a war, and it has guaranteed our box lunches before, and it tastes good hahaha! Yes, high flag is high flag, an airport I imagined.
