"What's going on with the engine EGT? It shouldn't be so low." The captain also noticed something strange about the No. 1 engine. The contrast between the two engines was too strong at this time. Even people who are not aviation professionals should be able to understand this.

A problem occurred.

Xu Xian didn't say a word. He knew that under normal circumstances, the current turbine engine would not be extinguished by rain. Otherwise, this kind of crystallization of many high technologies would be too much. However, in some special circumstances

Under such conditions, even the core of the turbine engine cannot withstand the erosion of rainwater.

Many people should be able to imagine that if the engine is soaked in water, it will definitely not be able to run. Although the environment in which the aircraft is now is not as good as being directly soaked in water, it is not much different. So from this point of view, No. 1

It is reasonable for the engine's EGT to decrease abnormally.

The captain was quite nervous at this time. The temperature of the EGT of the No. 1 engine dropped abnormally. He didn't know what would happen next, because all the manuals he had learned did not contain any information on what might happen in the so-called extremely heavy precipitation.

There is no description of the EGT reduction. Because of this, the captain did not know how to deal with such a situation.

Even if they know where the source is, the entire typhoon area, except for the eye area of ​​the typhoon, is now covered by the spiral rainband area. As long as the spiral rainband area exists, there will be precipitation. They

It's simply unavoidable.

Either rush into the eye area of ​​the typhoon, or rise to the top of the typhoon system. Obviously the former plan is more likely to be realized. However, if this continues, what will happen if the No. 1 engine stalls?

When both engines are running normally, they are not sure that they can completely and safely cross the boundary of the typhoon eye area, let alone if one engine is lost.

Once an aircraft has only one engine, it does not mean that it cannot fly. But the flight performance of the aircraft will be greatly affected, and the maneuverability of the aircraft will be severely restricted. Originally, the thin layer of airflow at the boundary of the typhoon eye area will

It will be extremely chaotic. If there is a problem with the maneuverability of the aircraft, doesn't it mean that the aircraft will be like a lonely boat in the angry sea, just drifting with the tide?

If that's the case, wouldn't it mean leaving your destiny to God's decision?

Such a situation is probably unacceptable to any professional pilot.

But the current situation is that they really don't seem to have a particularly good solution. As long as they do not leave the area affected by the typhoon, the heavy rainfall will not end, and the risk of engine No. 1 stalling will not disappear.

"Do you want to descend?" the helpless captain asked.

Now, due to their increased altitude, they are too close to the spiral rainband area, which makes the rain stronger. If the altitude can be lowered, the rain may be lighter.

"Don't descend!" Xu Xian denied the captain's statement without thinking: "Continue to rise. As long as we hold on for a while, we can descend. Now when descending, the plane will have to pass through the cloud wall area, and it will need to bear additional hail damage."

The dangers of impact and turbulence are more immediate."

The current situation is very simple, that is, there is no completely risk-free path to take. Xu Xian can only choose a less dangerous plan among various options. This is a helpless solution.

As soon as the plane descends, the plane will be subject to a sharply increased risk of hail strikes. In Xu Xian's view, the risk of severe turbulence faced by passing through the cloud wall area is not as high as the risk of hail strikes.

Severe turbulence caused by encountering turbulence only poses a theoretical risk of the aircraft disintegrating, but the risk of hail strikes is indeed real.

But once the hail hits the damaged windshield on the right again, the windshield will definitely not be able to withstand another impact. At such a high altitude, with such precipitation, and in such a low temperature environment, hypoxia may be just a less fatal factor.

factors. The surging freezing rain turned the people in the cockpit into ice sculptures in a short time. This situation cannot be solved by human power, at least Xu Xian has not thought of it yet.

Xu Xian would not put himself in a situation that he could not solve, so losing altitude was unacceptable to him.

"But what if we continue to fly at high altitude and the No. 1 engine stalls?" the captain asked with bright eyes: "It is difficult to start the engine in the air if it stalls in this environment."

There is indeed no description in the manual that heavy precipitation will destroy the engine, but after the engine stalls, if it is excessively cooled, the success rate of restarting the engine will be greatly reduced.

This is not the captain's imagination, but it actually exists in the additional instructions of the engine air start checklist. Normally, an overcooled engine refers to an engine that stalls for more than half an hour. However, this definition is for

Under normal circumstances, not only are they at a very high altitude, but there is also heavy precipitation around them. Under these circumstances, as long as the engine is turned off, the core temperature of the engine will drop rapidly and become a so-called overcooled state in a very short time. Once

Entering this state, there is basically no possibility of the engine successfully starting in the air.

This also means that as long as the No. 1 engine stalls, there is basically no chance of restarting it. Then they can only cross the boundary of the typhoon eye zone with a single engine running. Just thinking about this possible situation,

The captain felt a little shivering.

No one wants to taste the feeling of handing over your life to someone you have absolutely no control over.

"I know!" Xu Xian knew what it meant when the engine stalled in this situation of freezing rain, but he had no idea of ​​changing his mind. Even in this dilemma, Xu Xian's mood was still not serious.

Fluctuation: "If an engine stalls, we may still survive! But if the windshield is broken... we will definitely die!"

"Brother Xu, are you saying that even if the No. 1 engine stalls, we may still pass through the boundary of the typhoon eye area? But the turbulence over there is very strong, and it is close to an engine. Can we withstand it?" the captain said at the right time.

Questioned.

"Then find a place where the turbulence is not so strong and go in!" Xu Xian said in a calm voice, as if the scene described by the captain was just casual.

...

In the Huacheng control room, the shift director contacted the meteorological department and asked the meteorological department to transmit the typhoon's meteorological data to the regional control room. After all, the real-time typhoon data from the meteorological department is the most accurate.

Seeing that the entire southern region was enveloped by a huge spiral air mass, the supervisor on duty had to sigh that the scale of this typhoon was really extremely rare.

"Zhangzhou..." The duty supervisor quickly found the location of Zhangzhou Airport on the screen. At this moment, Zhangzhou Airport is at the boundary of the typhoon eye area. However, with the overall movement of the typhoon, I believe that

Soon Zhangzhou Airport will enter the eye area of ​​the typhoon, and by then, Zhangzhou Airport will usher in short-term good weather.

The shift director murmured to himself: "It's just like what he said!"

To be honest, even if the estimated movement path of the typhoon is obtained from TV, the appropriate alternate airport in the eye area of ​​the typhoon within the estimated landing time can be calculated in a short time. This calculation power alone has already made it possible for Taipei to

Many people are beyond their reach.

"Is the weather forecast for Zhangzhou Airport out?" the duty director asked his assistant. Even judging from the weather map, Zhangzhou Airport will soon become the only airport in the entire southern region that can land. However, for safety reasons, the duty director

Accurate forecasts from the meteorological department are still needed.

The weather forecast is more accurate in a shorter period of time, and the shift supervisor only needs the forecast for the next two hours. Only predicting the weather trend in the next two hours, given the technical capabilities of the Meteorological Bureau, is still quite informative.

.

The assistant has been with the duty director for many years, and he has already contacted the Meteorological Bureau in advance without the duty director's instructions. Now when the duty director asked, the assistant immediately replied: "The Meteorological Bureau said that it can take up to half an hour, Zhangzhou Airport

The weather will improve. Moreover, after the weather improves, it will last for about an hour and a half."

"Half an hour?" The shift director frowned: "They don't know if they can last half an hour."

To be honest, it is unacceptable for a plane that accidentally got into a typhoon to stay inside for even one second, let alone half an hour.

"Director, the Meteorological Bureau's so-called improvement in weather means light rain or less. In fact, as long as the rain reduces to moderate rain, the plane can land. And now the wind at Zhangzhou Airport is decreasing rapidly, and it will soon be

It can be reduced to below the standard. Therefore, according to the standard of landing, it does not take half an hour at all." This assistant did know some flight knowledge: "In addition... Director... Xu Xian

On the plane, even if it rains heavily, as long as the weather is not too extreme, I believe he can survive it."

For ordinary pilots, landing in heavy rain is risky. However, in the opinion of his assistant, Xu Xian should be able to handle it safely even in heavy rain.

"You really believe in him! He didn't do what happened before running off the runway?" Compared to the assistant's almost blind confidence in Xu Xian, the area controller next to him didn't think so.

"I hope you can have a professional perspective when looking at a problem. People outside follow the trend and blame Xu Xian. This is because they are limited by their professional abilities and have no choice. However, we can at least

We are in the same circle, can you please stop taking it so personally?" Perhaps this assistant was one of Xu Xian's admirers, and when faced with his colleagues' doubts, he rebutted bluntly without leaving any room.

"Ahem..." At this somewhat embarrassing moment, the supervisor on duty coughed twice and patted his assistant on the shoulder: "Go and contact Xingyou. After all, Xu Xian is on the plane.

...In addition, the matter will be reported to the bureau, and Xu Xian’s incident on the plane will also be named.”

The assistant glared at the controller, but still obeyed the supervisor on duty and walked away silently.

After the assistant left, the supervisor on duty said helplessly to the regional controller: "It's not like you didn't know he was obsessed with Xu Xian. Why did you say anything wrong about Xu Xian in front of him?"

"You can't say that? I'm just telling the truth." The area controller curled his lips and said, "It's just a person who is trying to gain fame."

The supervisor on duty had a headache: "I don't understand why you have such a big opinion against Xu Xian..."

...

A hangar at Luohang Flight Base.

A C42 was parked in this secret hangar, and on the side of the aircraft, Ye Qing and Ying Ruoqing stood side by side.

Ying Ruoqing looked at the C42 and was slightly disappointed: "This model has been finalized. It seems that it is difficult to equip it with laser weapons..."

"When the C42 was designed, laser weapons had not even appeared as experimental models, and there was no sign of weaponization at all. Therefore, I did not reserve a place for laser weapons at all. You should have expected this result.

...." Ye Qing spread his hands and said helplessly: "It seems that your trip was in vain."

If you want to install a laser weapon on the C42, not only the weapon mounting system must be changed, but the fuselage structure must also be changed, and the laser weapon has its own fire control system, which is not compatible with the C42's fire control system. If you want the C42 to use lasers

Weapons and even the fire control system also need to be modified.

Such a change is almost equivalent to designing a new model. It is obviously not cost-effective to design a new model just to install laser weapons.

No way, during the design period of C42, there was still no trend of practical use of laser weapons, and the key high-energy battery technology did not even have the slightest sign of being conquered. How could Ye Qing reserve a position for a weapon that has not yet been seen?

In fact, if it is some conventional weapons, the C42 may still be compatible. However, laser weapons are completely different from other conventional weapons, and the C42's weapon system is not compatible at all.

Ye Qing really did not expect that the core technology of laser weapons, high-energy batteries, could be conquered so quickly and without warning. Moreover, laser weapons were weaponized in a very short period of time.

"It's okay, I was mentally prepared for this." Ying Ruoqing looked just a little bit regretful, not overly emotional. Previously, when she applied to come to Luohang to investigate the suitability of C42 for installing laser weapons,

, Ying Ruoqing roughly guessed this ending.

The weaponization of laser weapons was completed so quickly that the domestic military community did not expect this result to happen. The C42 did not reserve a position for laser weapons, which was basically foreseeable.

Ye Qing was a little surprised to see that Ying Ruoqing had almost no mood swings. It seemed that Ying Ruoqing had guessed the result a long time ago: "So, you just came here just to make yourself give up? Is it necessary?

?”

"If it's just for C42 alone, then it's naturally unnecessary." Ying Ruoqing said calmly: "Laser weapons are weapons that represent the future, so naturally they must be paired with a weapon platform that represents the future. To be honest, C42 is already outdated...

..."
