Chapter 624: Flying Back

The oil has leaked!

If Qin Feng hadn't raced against time just now, if he hadn't turned on the afterburner, according to the time calculation, he would still be far from the airport now, and now, he had regained his precious time, and the runway of the airport was right in front of him!

The pointer of the fuel gauge in front of him had been reset to zero, and now he knew that the fuel tank was empty, and maybe the plane's engine was burning the last fuel vapor in the tank!

What to do?

Of course, turn off one!

Just now he turned on the afterburner, and now, since the fuel is leaking, he has to save the use of these fuel vapors, turn off the afterburner, and turn off an engine!

If it is like a Tomcat fighter, the two engines are more than a meter apart, and once one of them is turned off, it will cause a large yaw moment, and the pilot has to push the rudder at all times, otherwise the plane will fly off.

Of course, such a design is also reasonable, once in the battle, the engine is destroyed, it will burn and catch fire, more than a meter away, will not hinder the second engine, this is also the original intention of the design at that time, however, the various twin-engine fighters designed later, separated by rare, are generally side by side.

The J-7 is also designed in this way, and in the current situation, only one is left, and there will not be much yaw torque, so Qin Feng's operation is still no problem.

Hopefully I can hold on and make it until I land!

Qin Feng gently pushed the operating lever, according to previous experience, once the engine is turned off, the most terrible thing is the locking of the piloting system, once the pressure of the hydraulic oil is lost, then he will not be able to control the aircraft.

If it is fly-by-wire control, and the servo is also driven by electricity, then maybe it can be extended for a while, but now the J-7 is also an ordinary hydraulic control, but it is just a set of stabilization system, he must be gentle, every operation, must be in place, if the control is excessive, then it needs to be re-corrected, so it will be a waste of time.

Only one chance!

Qin Feng has faced many crises in the test flight, and in the current situation, he can completely cope with it, although his heartbeat is somewhat accelerated, but Qin Feng is still very calm, and finally, the J-7 fighter plane fell down along a beautiful gliding line.

"001, attention, it's a tailwind." The tower continued to remind him.

If he can fly back, he will also have to be stained with the light of the tailwind, in short, he is very lucky, but the tailwind will also bring certain troubles to the landing, that is, the landing distance will be longer.

Fortunately, on the runway of Factory 172, even the H-6 can take off and train normally, so Qin Feng doesn't care about sliding some more distances, the earth on both sides is rapidly approaching, approaching, and finally, the wheels and the ground are in contact, and there is a bump, just like that, the plane fell!

When it came to this moment, Qin Feng relaxed, as long as there was no problem with the landing gear, he had nothing to worry about, even if the engine stopped.

Wait, it seems that there is no roar of the engine behind it?

Just now, Qin Feng has been operating the fighter steadily, striving to land once, he doesn't even know when the engine stopped, in short, now that the wheels are touching the ground, there is no need to adjust anymore, Qin Feng sat on the fighter, slid and ran, the landing gear in front of him touched the ground, and then continued to taxi forward, put down the parachute, and finally, at the end of the runway, the plane stopped.

Unlike last time, Yang Lin in the rear cabin was still alive and kicking at this time, he opened the cockpit cover, stood up in the cockpit, held the partition frame in front of him, and said to Qin Feng: "Comrade Qin Feng, your flight is the most perfect!" I'll be your weapons operator, trust you completely, and you'll bring me back! ”

The first time, I was still afraid of wrecking, but this time, I experienced another serious accident, but was steadily flown back by Qin Feng, Yang Lin at this time was quite excited, he knew that this was a miracle, Qin Feng was so good at creating miracles, as long as Qin Feng was there, there was no fault that could not be overcome!

Qin Feng also stood up: "Don't blindly trust me, my legs are shaking now, you know?" ”

Flying is a sacred profession, every time you get on the plane, you have to be solemn, if you feel that you are lucky, you can handle it well, once you are careless, there may really be something wrong.

Just now, Qin Feng has always been very calm, but now, when he flew back, he really felt some cramps in his calves, and every time, it was like walking through the ghost gate.

If they run out of fuel and are forced to make a forced landing in the wilderness, then it is called dangerous!

Now that they have flown the fighter back, it's time to find out what the problem is, where is the oil leak?

When the two of them came down, the fighter had not yet been dragged into the hangar, and the engineers who ran over had already found the approximate oil leak point.

Fuel is leaking out of the skin of the wings, and although it is now leaking, it is clear that the difference is evident at a glance when it is soaked with fuel.

In order to increase the fuel load, fuel can be stored inside the wings, and now, is there a problem here?

No, it is said that the overall fuel tank of the wing is quite strong and cannot be broken, besides, the overall fuel tank of the wing has the ability to close itself, even if it leaks a hole, it can be plugged by itself, this is an experience that has been had since World War II, how can it leak out of the wing now?

The specific reason is to be pushed inside the hangar to know, and when the rivets of the outer skin are disassembled, the real culprit can be found, and the fuel tank is not leaking, but the oil hose inside, a quick connector, has been disconnected!

"It seems that the assembly process needs to be strengthened." Looking at this loose joint, Qin Feng also felt a sense of powerlessness, which was obviously caused by an assembly error.

In recent years, in the production plant of military aircraft, sometimes this phenomenon occurs, the assembly workers are not serious, and finally lead to serious accidents, which is also a problem in the reform, even a few years ago, even the 132 factory has also encountered, and later, Tu Lao formulated a series of responsibility systems, which can be regarded as effectively improving the quality.

Fortunately, I flew back and found the problem, if I fell, I fell apart, then I couldn't find anything, there was no cause of the accident, and I would always be terrified when I flew again in the future.

"Yes, we must strengthen the process, this aircraft, all the oil joints, all re-checked!" Chen Lao said. Now that we have found the problem, we must have a countermeasure, and we must not have a similar situation again!
