It was break time at this time, but there were some students in the library, and the library was not closed yet.
Zheng Bei easily found Jiang Yan Hai who was reading a book in the library, but when he saw the books Jiang Yan Hai was reading, he felt a little bad.
"Maintenance and Treatment of Common General Helicopter Faults", why are you reading 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 Yan Hai, almost starting from the shallower to the deeper. "These are all books read by the ground crew."
"They are books for ground crew, but there are also some books about mechanical maintenance and related helicopter manufacturing. Mainly because I feel that reading this kind of books has a lot to do with the elimination of special circumstances in my own flight."
"Because every fault is caused by a problem in these machines, it is necessary to understand their principles and the different feedbacks produced after problems with these parts and components, as well as the resulting situations, and confirm each other. In this way, when special circumstances are eliminated, it will be more precise and accurate, and there will be no misoperation."
"I found that there were problems with some different parts, but the final results fed back to the helicopter were similar. If the problem could be found as soon as possible, there would be more golden rescue time."
Jiang Yan Hai closed the book in his hand, looked at Zheng Bei and said.
Zheng Bei: "..."
I know what you said makes sense, but do you know that helicopter maintenance and manufacturing alone involve countless systematic projects, and it is already very difficult to figure them out. Anyone who can learn all of these can be regarded as a talent in the field of helicopter production and design.
So you told me you were a pilot?
The threshold for being a pilot was already high enough, but now it has become so high? Do you have to learn how to build an airplane?
"Jiang Yan Hai, you know that human energy is limited." Zheng Bei could only say tactfully.
"I know, thank you instructor, but you can take a test on some of my common specialties. I've seen a lot today." Jiang Yan Hai nodded immediately.
"Well, what should we do if the engine fails? How to implement it?" Zheng Bei immediately spoke.
"The most common way to recover from engine failure is through autorotation. Autorotation is a descending maneuver. If the engine fails, the main rotor is separated from the engine. The rotor blades are only driven by the upward airflow through the rotor. At this time, the engine no longer provides output power to the main rotor."
"The most common reason for autorotation is engine failure. If implemented, at high altitudes, if this problem occurs, immediately lower the propeller torque to the bottom. During this process, the rotor speed must be kept in the green zone, and the flight speed must be controlled according to the maximum speed allowed for autorotation of different aircraft types. The speed determines the rate of descent, and maintain a good heading."
"Start at a distance of 15 meters from the ground, reduce speed, reach a height of 3 meters from the ground, level the attitude, and raise the propeller pitch to cushion the landing."
"Hovering and autorotating at a low altitude, retracting the throttle, resisting the rudder, preventing drift, taking into account the attitude, raising the propeller torque to cushion the landing."
"This is a conventional engine problem, but there are different reasons for engine problems. What is mentioned above is when the engine completely fails, but with our latest successfully developed turboshaft-16 engine WZ-10 Attack Helicopter, it has several problems that can also cause such a situation to occur, but a few simple operations can eliminate such effects..."
Jiang Yan Hai explained it very carefully. Zheng Bei didn't know the principles of the internal operation of the engine... but Zheng Bei understood the handling methods he mentioned. These handling methods are actually included in some special situations.
That is to say, when the pilot encounters engine failure, he must first carry out these processing methods. If that fails, he will then forcefully land through autorotation.
But why these treatments are needed... they don't know.
Jiang Yan Hai has already stated this reason directly. There seems to be no difference between the two, because for pilots, 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 huge difference.
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 destined to be irreversible.
And every pilot is as valuable as gold. If you can determine immediately whether the engine problem is due to 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 Yan Hai!
Zheng Bei smiled bitterly, "Okay, let's go, let's go to the simulator and I will teach you how to handle some special situations directly. Our special situations are many and varied, but I can give you the summary. The rest can only rely on your experience."
"As for your learning style... if you think you can learn this way, then go ahead."
Zheng Bei What else can you say?
"Thank you, instructor." Jiang Yan Hai immediately began to pack the books.
He can borrow these books.
I followed Zheng Bei directly to where the simulator is. There is a two-seater simulator inside, and some teaching can be conducted directly in the simulator.
Similarly, the simulator also has a teaching mode. Zheng Bei directly starts teaching Jiang Yan Hai some special situations. Needless to say, the speed at which Jiang Yan Hai accepts knowledge. Often Jiang Yan Hai can memorize them all in his mind after Zheng Bei tells them once.
When Zheng Bei directly sets the same special situation in the simulator, and then starts direct operation, after looking at it again, Jiang Yan Hai can basically be determined.
Because as he said to Gong Jian and the others before, when Zheng Bei was operating and narrating, Jiang Yan Hai had already modeled it in his own brain, and then simulated the operation again, directly memorizing it in his mind.
After describing the operation once, the second time is directly performed by Jiang Yan Hai himself.
His operation is very fast, thanks to the reaction ability of Jiang Yan Hai. Although it is not as good as Zheng Bei who has practiced tens of thousands of times, even the real estimate is that he has experienced countless operations proficiency.
But his reaction speed still strengthened his operational ability, and there was 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 discovered that he had taught Te Qing to a great extent!
What kind of learning speed is this?! Although he had been mentally prepared for it, for the first time, Zheng Bei found that... he really couldn't understand it. If this were all like Jiang Yan Hai, how fast would it be to train a pilot??
Maybe something like World War II? That's too scary.
