"We can't fly." When estimating the current fuel consumption rate, Yang Lin came to a conclusion, his current fuel consumption is too fast, because it must be leaking somewhere, and now it is bubbling outward, the speed is quite fast, according to the current flow rate, it will definitely be all drained in a short time, and even they don't have enough fuel to go back!

What to do?

Qin Feng looked out the window, at this time, they were passing through a white cloud, when they came out of the white cloud, the trail was like a string of meat, and below, it was already a vast earth.

Now, it's the middle of winter, and the ground is hard, so if there's really no way, then they can only choose to make a forced landing!

At this time, the people in the base were also very nervous, and the failure encountered this time was also quite serious, once the fuel ran out, the plane fell.

"001 report, now I'm trying my best to get back to the airport, and if I can't go back, I'm requesting a forced landing." Qin Feng shouted over the radio.

When I heard the sound on the radio, the people inside the tower shook for a moment and made a forced landing, is it possible?

No, the chances of a crash landing are too small!

Although those fields look flat, as long as you look closely, you will know that there are a lot of ravines, there are ridges, there are aqueducts, even if it is only 30 centimeters above the ground, it is quite dangerous, after the fighter plane comes down at high speed, it hits the ridge, the landing gear may be broken, the landing gear is broken, and the nose of the plane is turned over, so that the two people inside the cabin are likely to rub against the ground, and then...

"No, if the fuel is completely drained and the airport is still far away, skydive immediately!" shouted from the tower.

After all, human life is the most important thing, and a good pilot is also a priceless treasure.

"This oil leak may be due to a lack of connection to a tubing, or it may be a design flaw." Qin Feng worked hard to operate the plane to return home, and said to the tower: "Only if I fly the plane back, can I find the reason and avoid similar problems, I won't parachute, people are on the plane!" ”

This is the responsibility of the test pilot, and no matter what danger he encounters, he will also fly the plane back!

"Yes, people are on the plane!" Yang Lin in the rear cabin was also encouraged, he didn't write his suicide note, this is unnecessary, once he really sacrifices, his family will understand, and he won't make trouble for the troops, besides, he believes in Qin Feng, Qin Feng will definitely be able to fly the plane back!

"Now, request to turn on afterburner." Qin Feng continued to shout on the radio.

The plane he piloted had two engines, so if it was a normal situation, if there was not enough fuel, he should turn off one engine and just fly back by one, so that he could save fuel.

This is also a unique operation of multiple engines, many patrol aircraft, are under the wing to hang the engine type, when performing the mission, in order to save fuel, sometimes will turn off the symmetrical engines on both sides, leaving only one or two, so that the fuel is greatly saved.

If it was under normal circumstances, Qin Feng should have turned off an engine, but now it's not, it's not that his plane normally consumes too much fuel, but that the plane is leaking oil, rather than letting the plane leak all the fuel, it's better to use it first!

How to use it? Of course, it is to turn on the afterburner, which allows the plane to have more speed, accumulate more energy, and fly back before all the fuel is consumed!

In the case of a certain distance, the faster the speed, the shorter the time, and the aircraft oil leakage must have a linear relationship with time.

When they heard Qin Feng say that he wanted to turn on the afterburner, the people below were first happy, and then worried.

Qin Feng is an excellent test pilot, in various situations, will find the most suitable way, now, the plane is leaking oil, simply open the afterburner back, this is not much of an idea, but now, after all, this plane is the second test flight, many subjects have not yet started the test flight, take the flight speed as an example, to increase little by little, fly little by little, now, Qin Feng directly turned on the afterburner, may suddenly accelerate too high, even, now with the fuel is constantly consumed, his flight, And maybe supersonic speed, a plane that flew only one sortie, and the second one flew supersonic? The risks involved are also significant.

But now, there was no time to hesitate, Chen Lao nodded vigorously there, so the commander of the tower said: "Agreed, you can drive afterburner, pay attention to the situation of the plane, if you can't control it, please parachute immediately!" ”

This kind of flight is destined to be thrilling, if in the process of acceleration, the plane flutters again, or even other problems, then it is necessary to parachute, and you can't hesitate, because, if you delay, you may not even have the opportunity to parachute!

"Understood." Qin Feng said, turned on the switch in front of the panel, if it was the first time, then this action is not easy, the various switches in front of the panel have long been unclear, but now it is different, although the dashboard is vibrating, but the vibration is not too strong, he turned on the afterburner, and instantly, he felt the surging thrust on his back!

The maximum military thrust of the Spey engine is only 54 kN, and after turning on the afterburner, the thrust has increased to 91 kN, and now, the two intact Spey engines have burst out with the maximum thrust, pushing the plane and starting to accelerate, and now, they are rushing for time, and the oil leak is rushing for time!

At this moment, Qin Feng's mind suddenly remembered a joke, a driver drove very fast, and the person in the car asked uneasily, why are you driving so fast? The driver replied that the brake was broken, and he had to drive back to repair it!

This is definitely the most unsafe, and the current J-7 is also unsafe, this kind of aircraft is undergoing a test flight that has never been done before, and in the second flight, it is necessary to increase the speed.

The Mach watch was slowly turning, turning, increasing in speed, and the ground below was sweeping backwards at a rapid pace.

"001, watch the glide line!" The time seemed to be very long, in fact, not even a minute had passed, Qin Feng had already piloted the fighter plane back!

Now, on the airport, all the irrelevant people are standing outside, looking at the north wind, there, Jian-7 is still leaking oil, pulling out a white belt in the sky, just when Qin Feng turned off the afterburner, this belt also disappeared!
