Chapter 249: Can't Learn

At this time, it is time to rest, but there are some students in the library, and the library is not closed yet.

Zheng Bei easily found Jiang Yanhai who was reading in the library, but after he saw the books Jiang Yanhai was reading, he felt a little bad.

"Maintenance and Handling of Common Helicopter Troubleshooting", why don't you see this?

"How do you read this book??" Zheng Bei couldn't hold back and asked directly, because he saw some books placed next to Jiang Yanhai, and almost all started from shallow to deep with this, "These are all groundwork reading. book."

"It's a book read by the ground crew, but there are also some books about mechanical maintenance engineers and related helicopter manufacturing, mainly because I think that reading this kind of book has a great relationship with the flight special exclusion that I will be doing."

"Because every failure is caused by a problem in these machines, find out their principles and the different feedbacks generated after the problems of these parts and components, as well as the situations that will lead to them, confirm each other, in this case, When excluding special circumstances, it is more precise and accurate, and there will be no misoperation."

"I found that there were problems with some different parts, but the final feedback to the helicopter was similar. If the problem can be found at the first time, there will be more golden rescue time."

Jiang Yanhai closed the book in his hand and looked at Zheng Beidao.

Zheng Bei: "..."

I know what you said is very reasonable, but do you know that helicopter maintenance and manufacturing are countless systematic projects, and it is very difficult to figure out these things. If you can learn all of them, He is already considered a talent in the field of helicopter production and design.

Turns out you told me you were a pilot?

The threshold for pilots was high enough, but now it has become so high? Have to learn how to build airplanes?

"Jiang Yanhai, you know that people's energy is limited." Zheng Bei could only speak politely.

"I know, thank you, instructor, but you can test some of my common traits. I've read a lot today." Jiang Yanhai nodded immediately.

"Well, what should I do if the engine fails? How to implement it?" Zheng Bei said immediately.

"The most common method of engine failure is to recover through autorotation. Autorotation is a descending maneuver. When the engine fails, the main rotor is disconnected from the engine. The rotor blades are only driven by the upward airflow through the rotor. At this time, the engine does not provide output to the main rotor. power."

"The most common reason for autorotation is engine failure. If it is implemented, at high altitudes, if this problem occurs, the lower propeller torque will reach the end immediately. During this process, the rotor speed must be kept in the green zone, depending on the type of autorotation. The maximum speed allowed is different and the flight speed is controlled. The speed determines the size of the descent rate, and the heading is maintained.”

"Start pulling at a distance of 15 meters from the ground, slow down, 3 meters above the ground, level the attitude, and raise the paddle moment to buffer the landing."

"Hover and autorotate at low altitude, retract the throttle, reach the rudder, prevent drift, take into account the attitude, and raise the paddle moment to buffer the landing."

"This is a problem with a conventional engine, but there are different reasons for the problem with the engine. The above mentioned is the case where the engine fails completely, but with the newly developed turboshaft-16 engine developed by Wu Zhishi, it has several A problem can also cause this to happen, but a few simple actions can eliminate the effect..."

Jiang Yanhai explained it very carefully, and Zheng Bei didn't know the principle of the internal operation of the engine... But Zheng Bei understood the handling methods he said. These handling methods actually exist in some special cases.

That is to say, when the pilot encounters the engine failure, he must first carry out these processing methods, and if not, then force the landing by means of autorotation.

But why through these kinds of processing...they don't know.

Jiang Yanhai has already stated the reason directly. There seems to be no difference between the two, because for the pilot, you always have to perform this operation.

It doesn't matter whether you know the principle or not, but Zheng Bei knows that there is a big difference here.

If any aircraft engine fails, the golden rescue time is only a few seconds. If a decision is not made in the shortest time, it is doomed to be irreversible.

And every pilot is a precious asset like gold. If you can determine for the first time whether the engine problem is because of these small problems or because it really fails, there will be at least ten more seconds of precious time!

The problem is... not everyone is Jiang Yanhai!

Zheng Bei smiled bitterly, "Okay, let's go, let's go to the simulator and I will teach you some special situations directly, our special situations are many and varied, but I can give you the summed up, the rest can only be It depends on your experience."

"As for the way you study...if you think you can study this way, go ahead."

What else can Zheng Bei say?

"Thank you, instructor." Jiang Yanhai immediately began to pack up his books.

He can borrow these books.

Follow Zheng Bei directly to the place where the simulator is located. There is a two-seat simulator in the simulator, and some teaching can be carried out directly in the simulator.

The simulator also has a teaching mode. Zheng Bei started to teach Jiang Yanhai some special situations. It goes without saying that Jiang Yanhai accepted the knowledge. Often when Zheng Bei explained it once, Jiang Yanhai could remember them all in his mind.

When Zheng Bei directly set the same special situation in the simulator, and then started to operate directly, after reading it, Jiang Yanhai could basically be sure.

Because as he told Gong Jian and the others before, when Zheng Bei was operating and telling, Jiang Yanhai had already modeled in his own brain, and then simulated the operation again, and directly memorized these in his mind.

After telling the operation once, Jiang Yanhai did the second time directly.

His operation is very fast, thanks to Jiang Yanhai's reaction ability, although he is not as good as Zheng Bei who does not know how to practice tens of thousands of times, even the real estimate has encountered an unknown number of skilled operations.

But his reaction speed still strengthened his operation ability, there is no second time!

All the special features can be learned by watching it once.

When it was close to twelve o'clock, Zheng Bei suddenly found that he had taught the special situation a lot!

What kind of learning rate is this? ! Although he had already prepared in his heart, for the first time, Zheng Bei found that... he really didn't understand. If it was Jiang Yanhai, how fast would he train a pilot? ?

Maybe something like WWII? That was horrible too.
