The designer of the fighter has to deal with these complex data many times, and every time he comes back, there will be a large amount of data, and if there is no good data processing software, he will rely on the naked eye, which is definitely the most upsetting.

The current computer screen is definitely not a color graphical interface, it is black and white, and the characters in it are constantly beating, which is enough to dazzle the most familiar people, but Qin Feng is tightly capturing those data, and soon, he found the clue.

Every time I flew to Mach 2.24, the pressure of the hydraulic oil inside began to be abnormal.

These are all data, and if you have graphing software, you can plot it as a wavy line, which has a high peak, and the peaks and valleys are much higher than normal.

"Stop." Qin Feng said: "Where is the data of this hydraulic oil?" ”

Qin Feng could recognize that it was hydraulic oil, but he couldn't recognize where it was, after all, there were many rudder surfaces that needed to be operated in the fighter. At the same time, in order to backup, there are several circuits on any rudder surface.

Hearing Qin Feng's words, the operator in front of the computer pressed the space bar on the keyboard, and immediately the interface stopped, and he also nodded and said: "Yes, the data of this hydraulic oil is not normal, this is the main hydraulic oil pipeline of the rudder!" ”

The oil pressure inside the main hydraulic oil pipeline of the rudder actually fluctuated significantly, and at the same time, Qin Feng also understood, no wonder he felt the rudder shaking under his feet.

But what does this have to do with the overall vibration of the fighter?

Qin Feng continued to think in his heart, the most important thing in this is the causal relationship, is it the fluctuation of the hydraulic oil pipeline that came first, the vibration, or the vibration that caused the fluctuation of the hydraulic oil pipeline?

"What about the other rudder data?" Qin Feng said: "Call it out and see if the other data is normal?" ”

Fighters not only have rudders, but also elevators, and flaps on the wings in front, which require hydraulic oil to operate, and at the same time, hydraulic oil also needs to be assisted.

If you have ever driven a car, you can easily step on the brakes when the engine is on fire, and if the engine is turned off, you can step on it for the first time, and you can't step on it for the second and third times.

Why is that?

Because the engine will provide power and increase the oil pressure, so that it can provide enough torque.

The same goes for warplanes.

In the beginning, the operation of the fighter plane relied on steel cables, just like the brake line of bicycles, and completely relied on the arm strength of the pilot, and flying the plane at that time was manual work.

Later, there is the hydraulic oil, and the pressure of the hydraulic oil comes from the help provided by the engine.

The engine is driven by a pressurized oil pump, so if there is a problem here, then all the hydraulic oil lines should appear in the same data.

Qin Feng thought of it, and the other technicians present naturally thought of it too.

Could it be a problem in this oil circuit?

"Impossible, we don't have any problems with the oil circuit." At this moment, a man said, "Our oil system has been working properly, and there will be absolutely no problems." ”

Qin Feng looked over, and it was a middle-aged man who spoke, his hands were holding the corner of the table, looking at the data on the screen, and at the same time, his mouth was categorical, and his head shook like a rattle.

It's not your oil circuit problem, why is there a problem with the oil pressure here?

"It must be a problem with the sensor, if there is a problem with the oil circuit, then all the oil pressure should change, now there is only one data problem, it must be the sensor!"

How is this data monitored? Of course, the sensor is used, as long as it is a machine, there will be a malfunction, and he insisted that it was the problem of the sensor.

Mr. Gu was also paying attention to him, and he said to the middle-aged man, "Lao Wang, are you sure?" ”

"Yes, I'm sure, how can we have a problem with our oil circuits? Joke. When Lao Wang spoke, his head was still shaking, and he would never admit it at this time, he would rather push it on the sensor.

"It can't be that there is a problem with the sensor, it is the oil circuit that is the problem." Qin Feng said: "When I was flying during the test flight, I could feel the footpegs of the rudder vibrating, if it was a sensor problem and the oil circuit was normal, how could it vibrate?" ”

As soon as Qin Feng said this, the designer named Lao Wang's face immediately turned red: "I said no problem, it's no problem, when you test fly, the soles of your feet may feel wrong, right?" ”

Hearing this, Qin Feng suddenly became anxious: "This comrade, I just mean my judgment, you haven't gone through any practice, how can you be sure that it's okay?" What if that's the problem? ”

"I designed this system, why haven't I practiced it? I said no problem, that's no problem, tell you, you are a test pilot, you are responsible for flying, how to judge the failure, how to deal with it, is our business, not yours! ”

This person called Lao Wang's voice was raised, and when he heard this, Qin Feng couldn't help but get angry: "What's wrong with your design?" We, the test pilots, are to verify whether the design is reasonable, whether there will be problems, and now that there is a problem, how can you be sure that there is no problem? ”

Seek truth from facts, what is right cannot be wrong, what is wrong cannot be right, and we must pay attention to scientific laws, but now this person is here to say that his system is fine, what is going on?

The people around were stunned.

Wang Yang was behind, stretched out his hand and pulled Qin Feng: "Comrade Qin Feng, let's go." ”

Walk?

Qin Feng looked at Wang Yang and could already see his intentions.

Many old engineers have a strange temper, and they can't argue with them, but now, they are test pilots, as long as there is a problem with the flight, according to the designer's requirements, there is no need to quarrel with them.

Seeing that Qin Feng was pulled by Wang Yang and signaled to leave, Lao Wang couldn't help but say: "I've been doing it for so many years, and there has been no problem, a small sensor failure, don't want to deduct basins for me." ”

Qin Feng has seen disputes, such as Song Lao and Tu Lao on the mapping of the MiG-21MF, although they are standing on their own positions, it is for the sake of the country, the route is different, and the goal is the same.

However, today, this one has opened Qin Feng's eyes, he thinks of himself as high, self-satisfied, and he will never think that he is wrong, such a person is over.

"I'm not leaving." Qin Feng said: "I insist on my opinion, the fault is on the main oil road operated by the rudder, not the sensor fault." ”
