Chapter 140: Sky Fire Burns the Sky(2/2)
The moment Xu Cang had this idea, the middle-aged man's mind was probably a little more aware, so he let go of his hands and pointed his right hand at the luggage rack above his head: "Medicine! Red and red bag!"
The flight attendant obviously hadn't figured out the situation yet, and hadn't heard the middle-aged man clearly, but he confirmed: "Sir, what did you say?"
"Medicine, asthma medicine, he had an asthma attack!" Xu Cang shouted immediately: "Flipped through the luggage rack above and looked for the red bag. There should be medicine inside."
Asthma patients generally prepare medicines for immediate needs.
The flight attendant then understood and quickly stood up to flip through the luggage rack.
However, the middle-aged man gradually curled up into a ball. Even when he had asthma attacks and breathing was not smooth, he actually covered his mouth and nose with his sleeves.
Seeing this, Xu Cang was immediately puzzled. Asthma originally suppressed normal breathing, causing suffocation. In this case, how could he still cover his mouth and nose?
Could it be that you are confused if you lack oxygen?
"Sir, don't cover it." Xu Cang was about to let the man let go of his mouth and nose.
But the man almost used all his strength and said with difficulty: "Gas, how can there be a gasoline smell here?"
At this moment, in the cockpit, Wu Taiming also sniffed, and immediately sat upright, looking at Shi Qi next to him with a puzzled look: "Teacher, what does it smell? Why can't I smell it?"
"This." Shi Qi was not sure, but he just vaguely felt something was wrong. However, due to the aging of the equipment, or the heating problems during the operation of the instrument, and the existence of high-altitude ozone, he would indeed smell some strange smells in the cockpit from time to time.
Shi Qi glanced at the various systems and found that there was nothing abnormal, so he didn't worry too much. Maybe his psychological effect might be simply some irrelevant smells.
Shi Qi waved his hand: "Forget it, nothing is wrong."
However, as soon as Shi Qi finished speaking, the ECAMs of the components all jumped out of information. Shi Qi's eyelids hopped, and he found that it seemed that the engine oil temperature was too high.
This alarm will only be triggered if the oil temperature is between 140 degrees and 155 degrees for more than fifteen minutes or directly exceeds 155 degrees.
Sure enough, Wu Taiming's reaction was also very fast. He immediately found that the oil temperature was already 152 degrees on the engine data indication. Too high oil temperature is a relatively dangerous situation. At many moments, the engine needs to be turned off, otherwise the engine will be damaged.
Shi Qi knew about how to deal with the excessive oil temperature. He immediately sat upright, disconnected the automatic throttle, slowly retracted the thrust handle of the No. 1 engine that was in trouble, and added the thrust of the No. 2 engine to ensure sufficient thrust. At the same time, he gradually corrected the side slippage caused by inconsistent thrust by the aircraft...
It has to be said that instructor Shi Qi's movements are quite sophisticated. The coordination between the throttle and the increase in the rudder volume is simply impeccable. When the aircraft continuously reduces the thrust, it has no deviation at all.
Usually, when the engine thrust decreases, the corresponding engine lubricant temperature will drop, which is a common sense problem. However, during the period when Shi Qi closed the accelerator, the lubricant temperature actually increased inversely with the decrease of the thrust.
This made Wu Taiming stunned and asked subconsciously: "What's going on? Why is the temperature still rising?"
Shi Qi wiped his stubble chin with his left hand and ordered to Wu Taiming: "Please keep the pole, look at the plane! I will control the rudder."
Wu Taiming immediately held the right side rod. At this time, the aircraft did not have too much deviation in the thrust, so the autonomous driving was disconnected. Therefore, Wu Taiming did not need to manually intervene in the aircraft's control, but only needed monitoring.
"Teacher, I'm looking at the plane! But what does this temperature mean? Why doesn't it fall at all?" Wu Taiming asked a question that he was puzzled.
Even if it is slower, the temperature of the lubricant will eventually drop, so there is no reason to rise.
Shi Qi's eyes swept back and forth over other data. When he almost received the thrust of the No. 1 engine to the slower train, he said with some uncertainty: "I see that except for the oil temperature, other data are all good. Could it be a cooling problem?"
Wu Taiming was stunned and asked in confusion: "Teacher, are you talking about IDG lubricant cooling system? Is that fuel-cooled?"
A portion of the fuel flowing out of the HMU hydraulic-mechanical assembly is used to cool the lubricant system of the entire drive engine and then flow back to the fuel pump or fuel tank.
Of course, this recirculation form will be closed by the fuel return valve in one finger, for example, when the engine is shut down or the fuel temperature is too high, almost above 52 degrees. This system will be controlled jointly by the changes in the ECU and FADE2 and the fuel flow rate, but Shi Qi cares more about it.
He pointed to the fuel flow meter of the next engine: "How come the fuel flow of the No. 1 engine is nearly half less than that of No. 2?"
"Can it be a thrust difference?" Wu Taiming said uncertainly: "And I see the past records of the mechanics, the fuel flow rate of the No. 1 engine seems to have always been less than that of the No. 2."
Wu Taiming said something is reasonable. After all, the thrust of the No. 1 engine is much lower than that of the No. 2 engine, so the fuel efficiency consumed is naturally much lower. Moreover, under normal circumstances, the fuel flow of the No. 1 engine was naturally lower than that of the No. 2 engine. The maneuver said that it might be a display error, and the specific reason is not clear.
It seems that such an exaggerated traffic difference is not impossible when the two are superimposed.
"I have read that record. As for the poor thrust," Wu Taiming's words made sense, but it was obviously not enough to convince Shi Qi. The main reason was that almost half of the fuel flow was reduced, and this difference was really amazing.
"What should I do, instructor?" At this time, the captain still had to come up with his ideas.
Shi Qi licked his lips. If he cut the engine without caring about it, no matter what the reason, he would determine the accident first and did not run away...
If it is really a mechanical failure, it may be a little better. If they deal with a slight flaw, it is hard to say. The main reason is that Shi Qi found that the rest of the system data is normal, the thrust reduction and the oil temperature increase are also in line with the description of the IDG system cooling problem.
So, Shi Qi decided to give it a try. He told Wu Taiming: "At low speed, IDG's system cooling is limited by fuel flow, and the effect is not good. I will start to add the throttle back in a while, and you stare at the oil temperature. Once the maximum temperature exceeds, no matter what, start the shutdown procedure directly. Do you understand?"
Wu Taiming calmed down a little. This was the first time he encountered a situation where he needed to turn off the car. He couldn't help feeling a little nervous, but he still nodded heavily: "I will stare, instructor!"
Shi Qi wiped his face. To be honest, he was a little nervous, but his psychological quality was excellent and he covered it up well. He made a quick decision, and Shi Qi was not a hesitant person. He immediately began to slowly increase the thrust of the No. 1 engine, and at the same time reduced the thrust and rudder volume of the No. 2 engine.
As the thrust of the No. 1 engine increased, the value of the No. 1 engine on the fuel flow meter began to rise. I don’t know when the oil temperature that had grown to nearly the limit suddenly stopped moving, which made Wu Taiming, who was frightened, breathed a sigh of relief.
Shi Qi actually had a small part of his energy on the engine oil temperature gauge. He noticed that the rising temperature had stopped. Naturally, he was happy and felt that he had done it right.
But before he could be happy, EACM's consultation information jumped out again. Shi Qi was taking care of the engine and the oil temperature, and he couldn't spare his energy, so he could only shout: "What's the situation?"
Wu Taiming looked at the display component and blurted out: "The vibration value of engine No. 1 is high?"
"What?" Hearing this, Shi Qi's face changed wildly. He was preparing to withdraw the accelerator of the No. 1 engine. But before he could move, he heard a loud noise. In the dark night sky, the No. 1 engine on the left of the plane exploded in the sky, and the flames surged into the sky!
