Chapter 3 Aerial Fuel Release
There was no noise on the radio, only the sound of the fire engine's horn in the distance.
Qin Feng knew that the base had already prepared for his forced landing.
Now, with 70 kilometers to go, he has to fly back in the plane!
Every second was so long, Qin Feng felt that his palms were already full of sweat when he didn't know when, and his white gloves were soaked.
"006, report data."
"The height is one thousand three, and the distance is about thirty." Qin Feng continued.
Thirty kilometers, from the sky, he could already see the straight runway, and even he could see the fire truck at the end of the runway, the ambulance was flashing the police lights, Qin Feng was still confident, he would definitely be able to fly back.
After the report, he habitually glanced at the rearview mirror, and this glance suddenly sank in his heart.
At the beginning, it was just black smoke, but now, you can see the flames popping out of the tail!
Fighter jets, the pilot's forward and lateral vision is very good, however, the rear vision is quite poor, so the general fighter has a rearview mirror, just like the rearview mirror of a car, simple and easy to use.
The MiG-21 is no exception, on the bulkhead at the top of the hatch, there is a rear-view mirror, but due to the blocking of the back ridge, this rear-view mirror is also better than nothing.
When it was improved to the J-7III, in order to increase the fuel load, the back was enlarged, and even a special periscope had to be used to see the back.
Now, when he saw the flames behind him, Qin Feng knew that the situation was completely complicated.
If there was only smoke and no open flame just now, it means that the combustion appeared inside the engine and did not burn outside, then the plane can still be driven back.
But now, the flames in the back are coming out, then it may burn the entire rear fuselage, if it burns to the hydraulic pipeline, not only the hydraulic oil in the pipeline is on fire, but the entire operating system will fail.
What to do?
"006, skydive now." At this time, Wang Gang's order came from the headset: "Your engine is already on fire, if the fire jumps to the front, it will turn the entire plane into a fireball, there is no time, jump immediately!" ”
The open flame has appeared, the fighter will disintegrate in the explosion at any time, Qin Feng's life will be fleeting, no matter how important the fighter is, it is not as important as the life of the test pilot.
Can't wait any longer.
"006 calls the tower and asks for oil to be released from the air." Qin Feng's voice suddenly startled everyone.
Fuel in the air?
In the J-7 fighter, there is still about a ton of fuel, if the fuel is released, the fuselage will be lighter, and the taxiing will be farther, and at the same time, if the fuel is cleaned, there is no need to worry about exploding when landing.
But how can this be?
The back is on fire, the front is draining oil?
"And the height, 006 asks for a try." Qin Feng said: "Now that it has entered the headwind, even if the oil is on fire in the air, it is behind my fuselage, and I am confident." Now the height is one thousand and one. ”
What to do?
Do you want to keep trying?
At an altitude of only 1,100 meters, the fighter plane, which has lost power, is still continuing to glide, and it must not be indecisive!
"Agreed, if there is a problem, jump immediately."
"006 understands." Qin Feng felt that his gloves were already wet, so he simply took off his gloves and directly used his fingers to flip the air oil drain switch.
Refueling in the air is a unique function of aircraft. For example, the maximum take-off weight of most aircraft is much greater than the maximum landing weight, and if the aircraft requires immediate landing due to a malfunction after takeoff, then the landing weight will exceed the maximum landing weight of the aircraft.
In the event of a forced landing, there is a danger that the landing gear will break. In order to reduce the weight of the aircraft and achieve the weight to land safely, it is necessary to release fuel in the air.
At the same time, if the aircraft requires a forced landing due to unexpected circumstances, especially when the landing gear cannot be lowered, if there is a large amount of fuel left in the aircraft, it is likely to be ignited by friction, high temperature caused by collision, and sparks during landing, and a fire will occur, or even cause the aircraft to explode.
Now, as Qin Feng turned on the air fuel drain switch, at the wings on both sides, aviation fuel suddenly came out.
At the oil drain, it can be seen that it is in a liquid state, but when it enters the air, it immediately atomizes and becomes fine oil droplets, which begin to diffuse.
If you look at it from a distance, you can see that the white oil mist begins to form rapidly, at the oil vent of the aircraft, because it is in a liquid state, so it is almost invisible, and at the back, it quickly expands into a thick white mist, and in the back, it can even expand to be thicker than the chimney of the power plant.
Qin Feng wants to make a forced landing, these fuels must be released, the design of the air oil vent was originally to avoid the engine vent at the tail, but now, the white fog has been dragged out for hundreds of meters, and when it reaches the back, it becomes more and more black, and it looks magnificent.
The silver-white J-7 fighter looks very small in the air, but behind it, it is followed by a thick smoke, and the further back it goes, the thicker the smoke becomes, sweeping across the sky, making people look shocking.
The smoke, which is jet fuel, has now been well mixed with the air, and once it is ignited...
At this time, everyone in the base can see it visually, some of them are holding binoculars, and some are looking up, looking forward to it, hoping that the hero's test pilot can return safely.
"Oh, no!" At that moment, a lookout post with a telescope shouted loudly.
In his telescope, he clearly saw the tail of the J-7, and it seemed that something had fallen, probably a burning oil droplet, and when it fell, it happened to ignite this white mist.
The spark of the stars can ignite the prairie fire, and as the flames jump into the white mist, this little kiss erupts incomparably hot and intense.
At this moment, the small flame ignited the white mist in front of it, and at a speed visible to the naked eye, this tongue of fire jumped backwards, and as the white mist thickened, this tongue of fire also began to thicken and become more fiery red.
In everyone's retina, the terrifying fire dragon was displayed, and in the sky, the blazing fire dragon was hundreds of meters long!
At this time, in front of this fire dragon, the J-7 fighter continued to fly forward bravely and fearlessly, as if this fire dragon was spit out by the J-7 fighter.
Everyone was sweating.
If this fire dragon burns to the front and burns to the oil vent, the J-7 fighter will immediately burst into flames.
"Skydive, skydive!"
On the ground, someone was already shouting.
Wang Gang was in the tower, his mood was extremely complicated, and at this time, he had missed the opportunity to skydive.
Compared with the prototype of the J-7, the J-7II has modified the way of catapult and life-saving, and the life-saving ability has been greatly improved, but it still has many defects.
The height is too low, the speed is too low, in this case, the ejection will come out, I'm afraid it will also ...
Wang Gang didn't dare to think about it anymore, he raised his head and looked at the J-7 fighter in the sky, Qin Feng, you must come back!
The fire dragon burned in the sky, but, miraculously, at a distance of about two meters from the J-7 oil port, it no longer jumped forward!
It can't be lit here, because the air currents blow it out.
The height of the J-7 fighter is only a few hundred meters, and it drags two meters of gradually spreading white smoke, and behind the white smoke, there is a fire dragon of hundreds of meters.
Inside the fighter, Qin Feng still had a firm gaze, forced landing, he must make a successful forced landing! There is no choice, to eject it is also death.
The ejection seats of later generations all have the ability of zero zero ejection, zero height, zero speed can be successfully ejected, but the ejection seat of the J-7, after the speed is less than 260 kilometers per hour, it can no longer be successfully ejected, and the delay of ejection also makes him have no time to react.
In the rearview mirror, Qin Feng could see the fire dragon dragging on the tail, sample, can you still burn it?
The fuel gauge hand has been reset to zero.
