On the operating rod of the fighter, there was a feeling of trembling, and at the same time, the whole body also had some trembling.

On the plane, it is inherently uncomfortable, this is not a passenger plane, the roar of the engine in the tail, the impact of the air flow on the rudder surface, will be transmitted to the plane, to the hand.

After all, this kind of aircraft is not yet fly-by-wire, and the difficulties of fly-by-wire control have not yet been mastered, and it now uses ordinary hydraulic operation, but with a simple stabilization system.

Qin Feng has been mentally prepared for these, that's right, after the missiles are mounted, the center of gravity of the fighter has changed, and the aerodynamic layout of the fighter has also undergone new changes, when the air blows through the missile, it will bring new vibrations, and these vibrations will be transmitted to the aircraft, forming the current situation, don't worry, there is nothing to worry about.

The fighter continued to climb.

"It's climbed to five thousand meters, and the shaking is a bit violent, and now it's starting to accelerate." Qin Feng shouted over the radio.

At this time, there was a feeling of riding in 212 on the crooked and uneven mountain road, Qin Feng's body, as the plane swayed left and right, he knew that the fighter plane was starting to want to go crazy again, and he had to play the role of a beast trainer again and control it steadily.

Height of five thousand, start accelerating!

According to the use scheme of this weapon system, it is necessary to carry four missiles and carry out ultra-low-altitude flight at sea level, of course, in the test flight, it is not possible to directly come up to the ultra-low-altitude test flight, the lower the altitude, the greater the air density, and the greater the aerodynamic impact.

First of all, it's five thousand meters, increase the speed, at this altitude, the air is already relatively thin.

You've completed level flight, and now, it's time to accelerate!

The two Spey engines in the tail continued to burn surgingly, and the fuel that continued to pour into the afterburner combustion chamber burned hotly in the combustion chamber, turning into high-temperature and high-pressure gas, which was sprayed out of the tail nozzle, pushing the fighter to fly forward!

The nose punctures the airflow, and more and more air, crashes into the airspeed tube, pushing the air pressure change inside, which is then displayed on the cockpit's instrument panel.

"The speed of the meter has reached 1,000."

"The speed of the meter is one thousand and one."

According to the plan, it is enough to achieve a meter speed of 1,002.

At an altitude of five thousand meters, there are no clouds left, there is a clear sky all around, and the arc edge of the earth can be seen in the distance, it is so tempting, Qin Feng's hand is on the accelerator lever, waiting to close the accelerator when he reaches one thousand two.

Now, the speedometer continued to increase the display, and Yang Lin in the rear compartment shouted: "Attention, adjust the error, add fifty." ”

The airspeed tube is error-free, which is well known, because it only measures the speed of the air, not the speed of the ground, which has less impact on the fighter, and for the bomber, in a long-distance flight, the difference between airspeed and ground speed, constantly accumulating, may make them lost.

So, this fighter-bomber also carried advanced navigation equipment on board, which could measure these errors, and now, it is time to correct the error by fifty.

Then, flying to one hundred and five is actually equivalent to flying to one thousand two.

Qin Feng looked at the airspeed gauge in front of him, and when he reached one thousand one hundred and fifteen, he turned off the afterburner, and then he pushed the operating stick and pedaled the rudder.

This is a dive plus left hovering maneuver to further test the arrival of the load, to see if the aerodynamic layout is reasonable and how it needs to be adjusted.

When he moved, he felt that the vibration of the plane was too great, and the operator in his hand was also dangling uncontrollably.

However, Qin Feng didn't care, when he made his first flight, there was a huge vibration, so that the dashboard in front of him couldn't be seen clearly, didn't he fly back like this?

Now, these difficulties can't help but be difficult for themselves.

Qin Feng made up his mind and continued to fly, and at the moment when he completed the circling dive, there was a sudden boom in his ears.

This sound was too loud, it was like rushing through a sonic boom cloud, Qin Feng's first reaction was, no, the engine stopped!

This movement is not only that the engine has stopped, but also that the engine blades have broken and hit something outside.

It is said that the quality of Spey engine is very stable, and now there is such a big failure?

If it's just a broken blade, it's not terrible, the terrible thing is that the broken blade is like a flying knife, cutting off other things, especially the various oil pipes outside, once broken, the fuel and lubricating oil that are sprayed out will burn up.

However, when he swept down, he did not see the engine fault light flashing, the speed of the two engines, oil pressure, etc., the situation was normal.

What's going on?

Qin Feng is very strange, this engine didn't turn off, it's not the engine's problem, could it be that the missile has fallen?

The missile is abnormally detached from the pylon, or even taken away from the pylon, so that there will be such a movement.

"Yang Lin, let's see if the missile has fallen." Qin Feng asked.

The first excludes the engine, and the second, it is a missile, after all, this time and the previous test flight, the difference is that the missile is hung!

In Qin Feng's position, it can't be seen, only in the rear cabin, and you have to turn your head hard.

Yang Lin also heard the movement just now, and knew that he had encountered an emergency again, as long as Qin Feng was there, he would not be nervous, he tried to turn his head and look at the left, two orange-red missiles were hanging on it, and then look at the right, the two missiles, both of which were also staying there in good shape.

"The missile didn't drop." Yang Lin shouted.

The missile didn't drop, so what? Qin Feng is strange now, it's not an engine, it's not a missile, and there can't be a problem with the body?

Qin Feng kicked the rudder, but found that the plane had no response, he was shocked, and pushed the rudder to the end hard, but there was still no response.

"083 report, rudder dropped." Qin Feng tried his best to use his calm voice to send back his judgment to the base.

The loud bang just now appeared when turning, and the tail of the J-7 has a tall single vertical tail, and the rear of the vertical tail is a rudder, and now, it is the rudder surface of this rudder that has fallen!

When the rudder surface fell, there was a dull sound, and the sound I just heard was the sound of the rudder falling!

Now many heavy fighters use double vertical tails, which can well avoid this problem, and now the single vertical tail, once it falls, the direction is uncontrollable.
