Return to 2000: Captain of the Great Powers

"B1437, confirm your current intention?"

Before Xu Cang and Richard finished their conversation, the controller's inquiry came over.Just now, their flight trajectory was rather strange, and they flew back, which made the Munich area control who had been monitoring them feel a little confused.

Moreover, from the point of view of the radar, the altitude of the plane is abnormal, and the speed seems to be abnormal. I am afraid that there is no problem.

While manipulating the plane, Richard glanced at Xu Cang. Such a distracted operation was not difficult for him, and he even managed to spare his energy to reply to the controller: "The airflow behind the no-fly zone was too strong just now. Returned. Now we're circling, dealing with some glitches on the gauges."

"Received." The Munich area control was slightly relieved: "Do you need help?"

"Help us contact the control tower of Munich Airport and let them upload the latest satellite cloud image of the Alps to our data terminal."

The Munich control side obviously paused, it seemed that they were taking notes, and quickly answered: "Is there any more?"

"No"

Before Richard finished speaking, Xu Cang interrupted: "Help me contact AVIC, and tell him that Xu Cang will contact Lin Ming by satellite phone in the near future, so that he can get ready."

"Aviation Industry?" Munich Control was obviously stunned: "Is it China's AVIC?"

"No way, it's the AVIC you think."

"Then Lin Ming is."

Before yesterday, no one in the Munich control circle knew who Xu Cang was, but after the British Airways 531 incident, the name Xu Cang was no longer an unfamiliar word in the Munich control circle.In contrast, no one knows Lin Ming's name.

Xu Cang said in a deep voice: "You don't need to know who this is. You just need to tell this sentence to AVIC, and they will know what to do."

It is also thanks to the development of communication technology now. If it was a few decades ago, how could this kind of cross-ocean connection be so easy?
The Munich control responded with a vague understanding: "Oh, I see."

"Please hurry up, we don't have much time." Xu Cang added.

"Got it, please keep circling in place. If you want to take further action, please let me know in time." Now that Xu Cang and the others have left the no-fly zone, they need to properly abide by the control, although there are no planes around.

"B1437 received."

As soon as the conversation with the controller was over, Richard immediately asked, "Why are you looking for AVIC?"

Xu Cang didn't hide it either: "The fuselage structure of this plane was made by AVIC."

"so what?"

The frequency of Xu Cang's left fingertip tapping on the top of the side stick became faster and faster: "If you want to know the limit of the aircraft fuselage structure, you must ask the manufacturer."

"The limit of the structural strength of the fuselage?" Richard's mouth twitched: "Why are you asking this?"

Xu Cang didn't laugh this time, but said in a very serious tone: "Didn't I say I'm going to do something very exciting?"

As a result, within less than a minute before and after this, the voice rang again on the control frequency, but it was not the voice of the previous controller, but a middle-aged male voice: "Mr. Chairman, we directly transferred the audio signal from Munich Airport, you guys You can talk to them directly."

Richard reacted, and gradually recognized the man's voice: "Mr. Heinlem, thank you very much."

"You're welcome."

Richard whispered: "This is the person in charge of the Munich regional air traffic control center."

Xu Cang didn't care who this person was, and soon there were some noises on the original area control frequency, followed by the voice of Bombardier's representative: "Xu Cang?"

Previously, the Bombardier representative had been waiting at the control tower of Munich Airport, but now he spoke first.

"I'm here!" Xu Cang pressed the call button: "Is the data of the satellite cloud image being uploaded?"

"Still compressing. The way of uploading data via satellite is not efficient enough. We need to compress first, otherwise the limit of satellite transmission will be exceeded."

In this era, the mainstream folks still use K to calculate the amount of data, and the ability to transmit data is far behind that of later generations.Moreover, the satellite is not operated by the Bombardier family. They just borrow the satellite for transmission and can only passively accept some transmission upper limit issues.

"Then hurry up and compress it." Xu Cang's words were a bit harsh, he didn't know the meaning of the call at this time, and the most important thing was that the person he wanted to call was not Bombardier.

The following operation will be quite dangerous, and Xu Cang's mentality will still be affected to some extent.

The representative of Bombardier didn't care too much. The information fed back from the Munich control just now showed that Xu Cang and the others had encountered a problem. It is understandable that Xu Cang was under great pressure.

"Can't you break through the peripheral airflow now?"

"Is there the latest report on the strength of the peripheral airflow? Just now there is a weather detection balloon near the control report, and the meteorological department should have been paying attention."

"Yes, the meteorological department just sent a new one." The representative of Bombardier hurriedly said: "The intensity of the cyclone has continued to increase since last night, and now the maximum wind speed on the periphery has exceeded 530 kilometers per hour."

"530 kilometers per hour." The corners of Richard's mouth twitched. The jet stream outside the cyclone was like a wind wall, which could not be broken through at all.

Even though he had expected it, when he heard that the wind speed outside the cyclone really exceeded 500 kilometers per hour, Xu Cang still felt dizzy.

The peripheral airflow is not only strong, but also very chaotic, and if one is not careful, the machine will be destroyed.

At this time, the representative of Bombardier asked a crucial question: "Xu Cang, can you pass through?"

For a moment, the cockpit fell into a deathly silence.

However, the silence didn't last long, and was quickly broken by Xu Cang: "I can't pass through, the influence of the airflow on the aircraft has exceeded the limit of the aircraft's control performance."

Richard looked at Xu Cang in surprise, he did not expect to admit it so bluntly.

"Then" the representative of Bombardier was probably also stunned: "Did this operation fail?"

At the moment when the Bombardier representative's voice fell, a ding-dong reminder suddenly sounded in the cockpit. Richard looked down at the draft column of the CDU: "The data has been transmitted."

"Untie it."

Richard hummed, and clicked on the data package, which indicated in English that this data cannot be displayed and printed, and there is an option to unlock on the right button.

This English prompt does not really indicate that the data packet cannot be displayed, to be precise, it cannot be displayed in text form, because it is an image information.

Soon Richard pressed the unlock button, and about ten seconds later, the original weather display on the navigation pages on both sides was overwritten, and a new weather graphic was displayed.

This is exactly the latest satellite cloud image.

In fact, the weather radar on the plane is also relatively accurate, but because of the influence of certain echoes and angles, it is impossible to intuitively feel the whole picture of the weather system, and the satellite observations shall prevail.

Previously, Xu Cang had used latitude and longitude to print out the location of Zhuangyuan Airport, and the uploaded data packets would not overwrite this information. Once the satellite cloud image information was unlocked, and then compared with the location of Zhuangyuan Airport that Xu Cang had shot, the two were immediately matched. The location relationship is clear at a glance.

"Damn!"

However, when seeing the screen displayed on the navigation page, Xu Cang's expression became extremely ugly.At this moment, Manor Airport has almost cut to the inner circle of the cyclone, which means that the window period is about to begin.

Xu Cang pursed his lips with an unusually serious expression.

The cyclone was moving faster than he expected, which meant that they had less time to make a decision.

Richard also noticed this problem, but he didn't say anything, but silently looked at Xu Cang, waiting for Xu Cang to make a decision.

It can be seen from the satellite cloud image that there is no way out to kill time, at most 5 minutes, and they only have 5 minutes of decision-making time at most.

"Xu Cang, what are you going to do?" On the radio, the representative of Bombardier was a little anxious. He could feel that this behavior had already half-stepped in the field of failure: "Is there really no other way?"

Richard saw that Xu Cang was thinking about something, so he replied instead of Xu Cang: "The airflow around the cyclone is far stronger than expected, and the ice accumulation is more serious than previously expected. Our data detection is estimated to have been blocked by ice accumulation. , and now the airspeed and altitude are displayed abnormally."

"Then why fly?" The Bombardier representative yelled: "Go back, this is a mission that is doomed to fail."

The airflow is too strong and the ice accumulation is extremely serious. Either two problems can cause the mission to fail, let alone a combination of the two.

You must know that these two problems are not all problems. It is not possible to succeed if they are solved, and there are still problems in the future?

There are so many difficulties and problems that people feel hopeless.

"No!" Xu Cang said suddenly: "There is still a way!"

"What?" Richard was taken aback, and looked down at Xu Cang, but saw that Xu Cang had already called up the SAT satellite phone page on the CDU, and at the same time entered a long series of numbers in it, Richard recognized Among them are the area codes of China.

That's a completely Chinese number!

Soon, Xu Cang pressed the dial button, and then Xu Cang switched the transmitter to the second one: "Give me 2 minutes."

Richard was taken aback, thinking of something, he should have called Lin Ming from AVIC to verify something.

I don't know if it's because the Munich area control is very efficient, or if Lin Ming was holding his mobile phone, the calling sound rang, and soon there was a man's voice, Lin Ming's voice.

"Xu Cang?"

"It's me!" Xu Cang licked his lower lip: "I'm currently on the CS300 aircraft and encountered some problems. You are the supplier of the CS300 aircraft fuselage. I want to get some information from you."

Lin Ming obviously didn't understand the current situation: "What?"

Xu Cang paused for a moment: "I just want to know if the CS300 aircraft can maintain the integrity of the fuselage when the gauge speed is 450 knots?"

"450 knots!?" Richard was shocked: "Xu Cang, what are you doing!"

The limit speed of most aircraft is more than 300 knots, and the CS300 aircraft is no exception.But when Xu Cang opened his mouth, he was going to exceed the limit speed by more than 100 knots, which was simply... too crazy.

The integrity of the fuselage?
What a horrible description is this?

Because on the flip side of that description, that would mean the aircraft disintegrated.

Because Richard was too nervous before, he kept pressing the talk button, so that the conversation between Xu Cang and Lin Ming was overheard by the Bombardier representative.

As a decision-maker at Bombardier, he can understand Chinese, but precisely because he can understand Chinese, he can understand the great horror in Xu Cang's words.

In the first VHF, the representative of Bombardier roared furiously: "Xu Cang, the speed limit of the CS300 is 340 knots. If it exceeds [-] knots, the plane will disintegrate."

However, Xu Cang didn't care about Bombardier's representative at all, he just asked Lin Ming calmly: "Is it okay? Can the CS300 aircraft withstand the speed of 450 knots?"

"Damn it, Xu Cang!" The representative of Bombardier found that Xu Cang didn't listen to him at all, and became even more angry: "We are an aircraft manufacturer, and what we say is the standard for everything."

"You are not, AVIC is." Xu Cang said flatly: "I know that the limit speed of CS300 is 340 knots, it is in the manual, so you don't need to tell me. And that is not what I asked."

At this moment, Lin Ming's voice sounded slowly: "Xu Cang, what do you want to do?"

Xu Cang pursed his lips: "There is a huge cyclone in front of me now, and I want to go to the center of the cyclone. But the airflow around the cyclone is too strong, and we can't break through."

How wise Lin Ming is, after hearing Xu Cang's words, he asked in an almost unimaginable voice almost immediately: "So... you want to go down from above?"

"What?" In the right seat, Richard was startled: "Get down from above, what do you mean?"

Richard reacted for a moment: "Impossible. Large passenger aircraft have extremely strong pitch stability. Even if all the engines are turned off, the plane cannot go straight up and down. As long as the plane wants to glide, it will not be able to reach the vicinity of the airport in the end."

Richard probably understood what he meant. If he couldn’t walk around the periphery of the cyclone, he would simply increase his altitude, turn over the periphery of the cyclone, and dive directly from the center of the cyclone.

However, fixed-wing aircraft have a natural disadvantage in going straight up and down.Otherwise, huge manpower and material resources will not be invested for the vertical take-off and landing of fixed-wing aircraft.

The central area of ​​the cyclone is not large. As long as the aircraft does not descend in a straight-up or almost straight-up manner, it is impossible for the aircraft to reach the predetermined position for approaching.

"No, yes!" Xu Cang said firmly.

"Is it possible?" Richard was stunned on the spot, and now what Xu Cang said was completely beyond his cognition: "How is it possible?"

The ideas in Richard's mind were colliding fiercely, but no matter what, he couldn't collide with even a little spark of rationality.

"Are you going to spiral down?" That was the only possible maneuver Richard could think of.

"No!" Xu Cang shook his head: "In the core area of ​​such a strong cyclone, due to the violent airflow, the air in the central area will be pulled to the periphery in large quantities. It's like rotating and stirring the water in a wooden barrel. A deep hole-like cavity will be formed in the middle of the vortex. Both water and air are fluids, so the two are basically the same in nature, that is to say, there will be a part in the center of the cyclone core area”

Richard's face paled instantly: "Is it really a vacuum?"

"Or it can't be said to be a complete vacuum, because there will be air added from other places, but it is already similar to a vacuum."

Richard took a breath, but then he thought of a huge question: "If it is a vacuum or something similar to a vacuum, won't the engine shut down when the plane enters?"

The engine needs fuel as well as air to run, otherwise the internal chamber combustion chamber would not be able to sustain combustion at all.If there is a vacuum outside or the air content is extremely low, the engine cannot continue to run at all and must be shut down.

This is why the rocket engine to go to outer space needs to carry a combustion accelerant, and obviously the CS300 does not have such a configuration.

What downward spiral?This is just empty talk. The plane will shut down as soon as it enters there, and it will spiral down. What a ghost!

"And there is another problem. The circling radius of this CS300 is still too large. As long as the circling descends, the aircraft will inevitably enter the outside of the cyclone. What we have to do is to stay in the core area as much as possible, just like a tornado, the core That part of the area is actually going to be a lot more stable."

"But if you don't hover and descend, you want to dive down?" Richard roared: "You know how much speed this will generate."

"I know!" Xu Cang said calmly: "So, I want to know whether the CS300 can withstand the speed of 450 knots. I will do everything possible to control the speed at 450 knots, which is my limit, but I don't know if it is the CS300. The limit of strength."

"Crazy, crazy, you really are a crazy!" The representative of Bombardier felt terrified. This time, he finally had a deep understanding of what kind of person Xu Cang is.

Xu Cang was very calm from the beginning to the end: "Give me an answer!"

On the satellite phone, Lin Ming was silent, he knew what his answer was about.However, he didn't answer immediately, but asked another question: "Xu Cang, if you can go down, can you go down?"

"Yes!" Xu Cang didn't say much, only these two words!

"Okay!" Lin Ming took a deep breath, his rough breathing could be heard even on the satellite phone, which shows the tremendous pressure he was under.

"Xu Cang, the CS300 can withstand a speed of 450 knots." Lin Ming said firmly, "This is my answer."

"Lin Ming!" Bombardier's representative roared furiously over the radio: "You are letting him die!"

"If he dies, as the initiator of everything, I will go down to accompany him." Once Lin Ming made up his mind, he would persevere: "However, my answer will not change now. Xu Cang, I use my life To assure you, the strength of the CS300 airframe can withstand a speed of 450 knots."

"Okay, okay, okay!" Xu Cang let out the wildest laughter: "If I can survive, then today I will show the world what China's industrial strength is!"

The glory of AVIC begins today!

PS· Tomorrow should be fine, I'm really too busy, there's nothing I can do!
