Return to 2000: Captain of the Great Powers

"Crazy, crazy, what a total lunatic."

The roar of Bombardier representatives echoed in the tower control room at Munich Airport, full of insolent anger and bewilderment.

Beside him, in addition to some necessary tower staff, there are also some bystanders, including Airbus COO Ronnie Covein.

The conversation between Xu Cang and the representative of Bombardier was through the loudspeaker, and Ronnie listened to the conversation between the two. Even Ronnie Covein had to marvel at Xu Cang's way of thinking that was completely different from ordinary people and surpassed common sense of great courage.

The Manor Airport located at the center of the cyclone was surrounded by a circle of extremely strong airflow, and it was impossible to pass through it. The only way was to descend from the sky and dive directly from the upper part of the cyclone.

However, for fixed-wing aircraft, diving is a technical task, at least not just pushing forward desperately.

Moreover, even Xu Cang solved the operation problem of the fixed-wing aircraft's dive.Under the dive, the speed of the aircraft must increase rapidly uncontrollably. This is the basic rule of energy conversion, and no one can restrain it.Perhaps, Xu Cang can limit the final speed of the plane through some means, but the final speed must be very, very high.

From Xu Cang's words, we can know that his idea is to control the final speed at around 450 knots, which is the minimum result after Xu Cang's estimation, but it is still within reach for most airliners. of.

"450 knots!" Ronnie opened his mouth, looking at the Bombardier representative who was very angry and even lost his composure, he had no intention of canceling.If it was him, it would have been the same reaction, 450 knots, this is crazy.

The Bombardier representative was pulling his hair and pacing back and forth in the tower monitoring room, looking extremely anxious.

For the CS300 aircraft, the maximum speed flight test conducted by Bombardier is 380 knots, which is a continuous overspeed test.For the flight test of instantaneous overspeed, the limit speed is [-] knots.

If you want to conduct flight tests at higher speeds, not only Bombardier's technical department, but also the test pilots have expressed their refusal.They believe that it is meaningless to test the limit speed of the aircraft, because such extreme situations will never be encountered in actual flights, and if the speed is increased to test, the aircraft has a high probability of disintegrating in the air.

The test pilots who conduct the test can accept certain risks, but it is difficult to accept the "suicidal behavior" of half-footed into the air and disintegrated, especially for such commercial test pilots.

Of course, if it exceeds 450 knots, there is a risk of disintegration in the air. This is the result of the theoretical calculation given by the technical department.At least, Bombardier doesn't know whether the aircraft's body strength can hold up at the real speed of [-] knots.

"Aviation Industry said yes." Beside the Bombardier representative, his assistant said silently, as if reminding, but also as comforting.

However, these words made the Bombardier representative even more angry: "He is risking our aircraft, no, it is a gamble."

If the aircraft cannot withstand the high speed and disintegrates in the air, most of the consequences and losses will be borne by Bombardier.But if the plane holds up, the publicity it will generate will be unparalleled.Because as far as Bombardier representatives know, even Airbus and Boeing do not conduct overspeed tests above the limit speed of [-] knots.If Xu Cang succeeds this time, then this time is a real, unshakable and undeniable manifestation of industrial capabilities, and AVIC may have a chance to emerge suddenly.

For the strength of aircraft materials, the requirements given by aircraft manufacturers are the lower limit, but the upper limit comes from the supplier of airframe equipment.

Therefore, as long as Xu Cang is successful, the spotlight will definitely be on AVIC instead of the aircraft manufacturer Bombardier.Because no aircraft manufacturer will reserve the structural strength of the aircraft to exceed Vmo by [-] knots, this is not a matter of safety margins, but rather the excellent materials of AVIC itself.

Originally, Bombardier wanted a fuselage with a strength of [-]%, and at the same time reserved a safety margin of [-]%, but AVIC directly gave it a fuselage of [-]%.

Under such circumstances, the final performance of the fuselage strength is [-]%, so the glory will basically only belong to AVIC.

It was this knowledge that made the Bombardier representative so irritated.

"Does Ryan Valette know that things have developed like this?" Airbus COO Ronnie looked at Bombardier's representative with a hint of joking.

He didn't think there was anything wrong with Bombardier's representative's reaction, he just found it interesting that Xu Cang coerced Bombardier.

And Ryan Valet is the president of Bombardier C Series Aircraft Co., Ltd.

The representative of Bombardier shuddered, only feeling angry and annoyed. Now it has become a glorious glory to AVIC, and a shameful failure to Bombardier's embarrassing situation.

He didn't refute anything, but he didn't want to talk to Ronnie Covain either.

However, Ronnie was not angry, but said slowly: "I don't know what agreement you have reached with Xu Cang. However, if Xu Cang planned this matter in advance, then obviously you are not his opponent at all." .”

The representative of Bombardier's face turned pale, his emotions gradually quieted down, and he didn't know what he was thinking.

Ronnie watched the Bombardier representative's expression change, tightened his clothes, and leaned back in the chair leisurely, looking very relaxed.

In the cockpit, Richard was always in shock after hearing what Xu Cang was thinking.The way the fixed-wing aircraft swooped reminded him of something else, something that happened more than 20 years ago.

"Look at the plane, I'll go back and check the cargo." Xu Cang told Richard while unfastening his seat belt: "Contact the control, we need to ascend to the altitude of FL330, and go around to the top of the cyclone from above. .”

In fact, Richard also felt that Xu Cang's actions were simply audacious: "Xu Cang, according to your opinion, after entering the central area, the engine must be turned off, you can't keep the two engines turned off forever, can you? "

"It's okay, the area similar to the vacuum should be a funnel shape, and the air content is higher as you go down, so you won't be missing the environmental conditions for the engine to run." Xu Cang just took off the seat belt: "Indeed, we It is not possible to approach with two engines off, so, in the right area, we will try to re-ignite the engines."

"You want to start the engine in the air?" Richard frowned: "Can the flameout protection of the PW6000 maintain flight in low-concentration air?"

The current aero-engine itself will compress the air sucked into it, and it will be compressed step by step.It is for this reason that aeroengines are divided into low-pressure systems and high-pressure systems.If the outside air content is relatively low, it can almost reach sufficient pressure after being compressed step by step by the compressor of the high-pressure system.

Moreover, many aero engines will have flameout protection, whether it is the latest model PW6000 or the most popular CFM56 in the civil aviation field.

Under certain conditions, the aero-engine will continuously ignite the combustion chamber to prevent it from extinguishing, which is the flameout protection.

However, Xu Cang did not have much confidence in the effect of this flameout protection.

"The compressor effect of the PW6000 is not that strong, and the air source of the engine will be insufficient. I tend to think that the flameout protection will not be effective." Xu Cang said: "Why don't you read the content of the engine re-ignition in advance?"

In the CS300 aircraft, an in-flight start of the engine is said to be an engine re-ignition, referring to Airbus Aircraft.

"I am very familiar with the CS300 manual, so I don't need to read it." Richard shook his head: "If the PW6000's requirements for the air source are not met, causing the engine to stall, then according to what you mean, the plane will almost reach a lower level." A relatively sufficient air source can only be obtained at high altitudes, and it takes time for the PW6000 to restart.”

Xu Cang understood Richard's oblique question: "Yes, you understand well. We only have one chance to restart."

Richard was startled, then gritted his teeth: "You are really straightforward."

They began to rush down from 6000 feet, and they expected to level off below 2 feet. You must know that the altitude of Manor Airport is more than [-] feet. If the plane descends too low, it will be inconvenient to approach.In other words, they have to dive more than [-] feet.

Richard hadn't done a dive, but he could imagine the rate of descent to be at least over six thousand feet per minute.Under such circumstances, the plane will only take more than three minutes from the start of the dive to leveling off.That's not a lot of time.

You know, the starting cycle of a standard PW6000 takes more than two minutes.That is to say, during the dive, they only have one chance to complete the start.

If they haven't started well below [-] feet, their situation is more dangerous.

Xu Cang mentioned that the air content will be higher at low altitudes, so in other words, the airflow at low altitudes will also start to become fierce.Even if it can't compare to the terrifyingly strong airflow on the periphery, without the support of the engine, once the plane enters the turbulent area, it will be difficult to control.

And, below 3000 feet, you're deep into the Alps.The average altitude of the Alps is more than [-] meters, which is exactly [-] feet.If the aircraft cannot be controlled below [-] feet, there is a danger of hitting a mountain at any time.

It is not only a matter of the structural strength of the fuselage in a dive situation, but also the timing of restarting the engine must be accurately grasped.If you start too early, it is easy to fail because the altitude is not low enough, which means that the only opportunity is lost. If you start too late, the altitude of the aircraft is too low, and it is easy to hit the mountain, which is really a big difficulty.

Richard felt that there were death points everywhere, and if he was not careful, he would die.

"If we don't seize the right timing to start" Richard asked with some guilt: "Xu Cang, what should you do?"

Xu Cang just stood up at this moment: "As long as it doesn't disintegrate in the air, everything can be solved."

Richard was taken aback, he could feel the unparalleled confidence in Xu Cang's words.This is not to be brave, but Xu Cang really thinks so.

"Are you serious?"

Xu Cang pulled the seat back: "I said, for me now, there are only possible questions, not technical questions."

The implication is that the disintegration of the aircraft in the air is an objective problem, and no one has the ability to turn around, which belongs to the category of impossibility.The series of problems caused by missing the timing of engine start are technical problems, because theoretically speaking, the huge speed generated by the dive can give the aircraft a lot of operating space.

However, without the power support of the engine, the anti-turbulence ability of the aircraft is very weak, and it is difficult to control the aircraft only by the pilot's operation.

However, difficult does not mean impossible, at least Xu Cang thinks so.

"Maybe after a while, the mid-air disintegration is only a technical problem on your side." Richard said with emotion.

In the past, in many people's minds, the breaking of the wing was not a technical problem, but an objective problem that must die.But Xu Cang has already demonstrated with iron-like facts that the broken wing is still a technical problem.

Xu Cang was slightly stunned, knowing that this was a compliment from Richard, he stepped out of his seat: "Probably not."

"Should." Richard's mouth twitched: "Forget it, you go, check the goods, I will contact the control and express my intention."

As long as it is in a non-no-fly zone, any flight intention needs to be reported to the controller, regardless of whether there are planes around.

The reason why Xu Cang wanted to check the cargo's fixed situation was mainly because the plane was going to dive soon.If a part of the cargo in the passenger compartment is not fixed properly, it will be disengaged and hit the cockpit, the consequences will be disastrous.

Moreover, another issue is involved, that is, the center of gravity of the aircraft.

When arranging cargo in the passenger cabin, the location of the cargo is carefully calculated and calculated by the Lufthansa stowage department.Once the cargo in the passenger compartment is unfastened, in the dive state, a large number of cargo will gather in front of the aircraft cabin, causing the center of gravity to move forward significantly.

The range of the center of gravity of the aircraft is limited, and there are slight differences according to the layout of the aircraft.However, if the center of gravity goes out beyond the limit, it is very likely to adversely affect the control of the aircraft.In the most extreme case, Xu Cang may not be able to pull the plane up, that is, after the center of gravity exceeds the limit, the operation of the plane in pitch may be controlled.

In the case of a dive, the descent rate of the plane is too high, but if it pulls up later, it is the difference between life and death. Xu Cang does not want to die because of the problem of the plane's center of gravity.

"Tell me, you don't need to tell me, just pull it up." Xu Cang ordered, and walked out while holding the bulkhead with one hand.

Although it is outside the cyclone now, it is still very bumpy. Xu Cang needs to be more careful when checking the fixed condition of the goods.

When Xu Cang went out, Richard immediately allocated part of his energy to call the control: "Munich control, request to ascend to FL330, heading 170."

Anyway, there is only one plane in the area now, and Richard didn't even bother to say the call sign.

"B1437, confirm the ascent to FL330?" Obviously, the area control side can't understand Richard's meaning.

However, Richard didn't have the time to explain to the regional control the crazy operation they were going to carry out in the near future. He only needed to get the permission of the regional control.

"Is the upper end of the no-fly zone still at [-] feet?"

Munich regulation: "The upper limit has not changed."

"Good!" For Richard, this is good news.Because the scope of the no-fly zone is determined by the range affected by the cyclone, the top height of the no-fly zone has not developed, indicating that the cyclone has not developed upwards, which means that the cyclone has entered a mature stage, and the probability is No more development, but the bad news is that this stage is at its peak of intensity.

Richard pondered for a moment: "We are going to cross the cyclone area from an altitude of [-] feet and reach the center of the cyclone."

"And then?" The Munich area control suddenly said.

"Huh?" Richard was a little displeased. Is the area control so curious?
Perhaps because he realized that he was talking too much, the Munich area control immediately changed his words: "B1437, you can ascend to the altitude of FL330, heading 170, agree."

"Thank you." Richard dealt with it casually, and immediately freed a hand on the mode control panel to adjust a new height for himself, but suddenly remembered that the height performance was abnormal, and he looked at the supercharger panel. He hesitated for a while.

Because the airflow in the cyclone area is too strong, they must go up to the altitude first, and then they can fly to the 170 heading, otherwise the plane will still repeat the same mistakes as before.

Not long after, with the sound of footsteps, Xu Cang returned to the cockpit. He looked at the instrument: "The application was rejected?"

"No." Richard shook his head: "Xu Cang, the speedometer doesn't matter. If the altimeter doesn't work, I need to deal with it a little bit."

As he spoke, Richard pointed to the supercharger panel.

Xu Cang was taken aback for a moment, but he didn't expect the hero to see the same thing. Xu Cang also tried to actively relieve pressure when the altimeter was unavailable before.Replace the barometric altimeter with the cockpit altimeter.

This kind of operation is irreversible, and Xu Cang was still patrolling the cabin just now, it is impossible for Richard to take the initiative to release the pressure before Xu Cang came back. In addition, this method also needs Xu Cang's permission, maybe Xu Cang has some other ideas Views.

"Do you want to relieve pressure?" Xu Cang sat back in his seat and asked casually.

Richard froze for a moment: "You know?"

"Of course I know, I did it once." After Xu Cang sat down, he put on his seat belt.

"Have you ever done it?" Richard took a deep look at Xu Cang. He remembered that Xu Cang had personally practiced the method of reducing the ground speed in the face of a strong wind. Now he even took the initiative to relieve pressure. Is there anything that Xu Cang has not used?
Richard pondered for a moment: "Is it possible?"

Xu Cang nodded: "It was feasible for me that time, but it was not a CS300 aircraft, and the model was different. The principle should be similar."

"The working principle of CS300's cockpit altimeter follows the mainstream, and there is nothing original. Since it is feasible, I am relieved. I have not used it in actual flight." Richard looked at Xu Cang: "Then Put on an oxygen mask?"

"No need!" Xu Cang shook his head: "Now the light is good, the visual conditions are good, and oxygen is very precious. Let's visually climb over."

"Oxygen is very precious?" Richard couldn't understand Xu Cang's meaning: "The oxygen system of the plane is completely sufficient for our use, there is no need to save it."

The oxygen system in the cockpit is not the same as the oxygen system used by the passengers in the cabin. The oxygen system in the cockpit lasts much longer than that in the cabin. At least there is no need to use it sparingly. Xu Cang’s argument is unreasonable.

However, Richard soon realized Xu Cang's intention: "You want to leave it to the people in the manor?"

"If there are some emergencies over there and you need to inhale oxygen, the oxygen on the plane may save your life." Xu Cang adjusted his seat slightly: "It's okay, now we are close enough to the cyclone, and we can roughly judge the height by visual inspection. Spiral up, and then fly to the central area."

Due to the lack of reference objects in the air, especially when the distance is relatively long, I feel that I am higher than the clouds. In fact, I don’t know that I am lower than the clouds until the plane flies closer.This visual error is very common.However, if the visual conditions are good and the distance is close enough, this kind of error will not be too outrageous.

Richard looked at the mountain-like black cloud cyclone, hesitated for a moment, and agreed with Xu Cang's opinion.

"Let me talk to the controller." Xu Cang pressed the speaking button: "B1437, there is something wrong with our altimeter, and now we are circling upwards on the spot, visually crossing the cyclone area, and the altitude range is between [-] feet and [-] feet. "

Thirty thousand feet is the top of the cyclone, and the plane must be higher than this altitude.And [-] feet is roughly equivalent to the ceiling of the aircraft. Of course, it is actually higher, but this time there is more cargo, and the ceiling is basically [-] feet.

It is precisely based on this consideration that Xu Cang gave his high range of activities based on this.

"Okay! B1437, end the circle."

"End the circling newspaper!"

Xu Cang replied, and turned his head to look at the cyclone: ​​"Come on."

Richard nodded, filled up the throttle, and at the same time raised the aircraft to a five-degree attitude to ensure a reasonable thrust value and attitude for cruising and climbing.

For Xu Cang and Richard, height and speed are just auxiliary parameters, and they have too many ways to prove their status.Therefore, Xu Cang didn't pay too much attention to Richard's operations. He believed that with Richard's ability, these things could still be done well.

Under the action of the huge thrust of the two PW6000s, the plane began to climb rapidly, and Xu Cang's face was a little dignified. Anyway, there are some things that he can't control, even if Lin Ming used his life to ensure that the fuselage structure of the CS300 plane can It can withstand a high speed of 450 knots, but in history, it is difficult for large civil aviation airliners to fly at this speed.

On the contrary, there have been a few times when they continued to accelerate due to entering the spiral, and eventually disintegrated due to excessive speed. This was a lot of pressure for Xu Cang.

Unlike a broken wing, the disintegration of the plane in the air is really completely unsolvable.

I don't know if it was a trance or something, after a few minutes, Richard said suddenly: "It's almost there?"

Only now did Xu Cang come back to his senses, glanced at the cyclone cloud not far away, and then used the cloud as a reference to estimate the rate of ascent of the plane: "Can't move up?"

"Yes, it feels like the rate of increase is less than five hundred."

"Well, it's ok, let's turn to the course." Xu Cang gave Richard an order, glanced at the value of the course 170 preset by Richard on the mode control panel, and immediately reported to the control: "B1437, Altitude is OK now, turn to heading 170?"

"Received, heading 170 is agreed."

"Ok."

Xu Cang responded casually: "Let's go."

Richard hummed and steered the plane to heading 170.Even if the static pressure port and the pitot tube are out of use, the heading indicator can still be used, which does not affect the heading control.

Obviously, the altitude of the plane should be far higher than the expected [-] feet at this moment, and it might not be approaching [-] feet.Perhaps it was because it was too far away from the cyclone, and the airflow was much more stable than that of the bottom when passing over from above.

The plane was originally not far from the center of the cyclone in the horizontal space, and it flew directly above the cyclone after flying for five or six minutes.

Previously, on British Airways 531, at the moment when the No. [-] engine exploded, the glimpse of the center of the cyclone was deeply engraved in Xu Cang's heart at that time. The shocking scene like a maelstrom in the sky may never be forgotten in his life. up.

However, the light was not good at that time, and part of it was hidden in the darkness, and the sense of oppression was actually stronger.The light is good now, and I can see the whole picture of the cyclone. Although there is still a sense of powerlessness in the face of nature, the shock is not as good as that of British Airways 531.

"Okay!" Xu Cang compared the satellite cloud images and confirmed that the current location is near the sky above the Zhuangzhuang Airport.

Then, Xu Cang quickly switched off the weather radar, and the previously uploaded satellite cloud image disappeared and was covered by the real-time weather radar echo image.

Richard habitually bared his teeth, which was one of his nervous expressions: "What now?"

"Now our altitude is much higher than [-] feet, there is no need to dive from here, and we can't dive from here." Xu Cang looked up at the pressurized panel: "It's time we need to know the accurate altitude information, ready Let go."

Richard nodded: "Put on the oxygen mask first."

Xu Cang hummed, took a deep breath, calmed down, and then squeezed the oxygen mask out of the box on the left.Xu Cang had never used a CS300 oxygen mask before. After a little research, he probably found out how to use the Knock, and put it on his head.

Unlike the oxygen mask of the Boeing 737, the oxygen mask of the CS300 is a face-covering type, that is, it comes with windproof glasses, covering the entire face, instead of only covering the mouth and nose like the oxygen mask of the Boeing 737.

Xu Cang is happy to see this kind of design, after all, he has the experience of broken windshield glass.If the oxygen mask of the 737 was the same as that of the CS300 at that time, it would at least make it easier for Xu Cang to see.

Without thinking too much, after putting on the oxygen mask, Xu Cang glanced at Richard, and found that Richard had already put it on, and was just waiting for Xu Cang.

After the CS300 aircraft detects that the pilot is wearing an oxygen mask, the communication panel will automatically switch to the mask mode, instead of manually switching like some old-fashioned 737s.

Feeling the huge breathing sound brought by the oxygen mask, Xu Cang's heartbeat gradually calmed down: "Okay, let's start!"

Richard heard Xu Cang's voice, and directly opened all the outflow exhaust valves manually.In an instant, Xu Cang could hear the sound of violent airflow, which was the movement of the pressurized air inside the cabin being discharged outward.With the discharge of pressurized air, the cabin altitude of the aircraft is also rising rapidly.

The cockpit altimeter of CS300 is a standard mechanical type. When the outflow valve is fully opened, the pointer starts to rotate clockwise continuously, and the index increases wildly, and finally stops directly at [-] feet.

Waiting for the cockpit altitude value to stabilize, Xu Cang glanced at it: "Circle and descend until the altitude is thirty-one thousand feet."

This was not difficult for Richard, he took off the throttle slightly, and the plane immediately began to descend.

"Take control of your speed, ideally near stick shaker speed."

Richard looked at Xu Cang with some surprise: "This is not easy, I can't see the exact speed, so I can only try it out."

A large number of pilots can judge whether to stall by the feeling of the rudder surface feedback to the driving system.However, like Airbus, CS300 is a fly-by-wire signal, and the actual stick force is simulated, which cannot accurately reflect the chattering of the rudder surface due to the imminent stall.

But who is Richard?

He could tell when the plane went into a stall by the uncontrolled dip of the nose.

Of course, this is based on the relatively stable airflow at this time.If it is too messy, this perception is prone to problems.

As the throttle was always kept high, and under Richard's deliberate control, the speed of the plane's circling and descending was not fast.Moreover, the reason why Xu Cang asked Richard to seek the minimum speed is also to control the turning radius, otherwise the speed is too high, and the turning radius will increase accordingly, and when the distance is close to the sky above the cyclone, it is difficult to control the entry point of the dive.

Both Xu Cang and Richard were very patient, they were not in a hurry, and at this time they were most afraid of being impatient.

The reason why Xu Cang did not dive at a high altitude is that the potential energy converted by the seven thousand feet altitude difference is too large for Xu Cang to handle, and there is still some air content in the seven thousand feet altitude space. For some, even if the engine is turned off artificially, if you want to dive down, you can only push the rod with all your strength.

In this way, the speed of the plane will be completely uncontrollable.

Xu Cang doesn't want to artificially force the plane to dive, but wants it to fall naturally, and Xu Cang is the one that prevents it, but the one that catalyzes it.

As the altitude of the aircraft decreased, it was already approaching the top of the cyclone.When the altitude difference between the two decreased, the aircraft had already begun to be affected by the cyclone turbulence, and the aircraft gradually began to bump.

"Xu Cang, the speed can't be reduced anymore, I'm a little bit out of control."

Once the plane started to turbulent, Richard's perception of the change in the state of the nose would be inaccurate, so he didn't dare to try the stall again.

"It's ok, this speed is ok." Xu Cang looked up at the cockpit altimeter. At this time, the altitude was almost [-] feet, so he held the steering column: "Take control."

"Hand over control." Richard took advantage of the situation and handed over control of the plane to Xu Cang: "Xu Cang, what should I do next?"

Xu Cang was still controlling the plane to circle and descend, while dividing his energy: "Don't worry about the engine, let it shut down naturally, wait for my password, and carry out the operation of re-ignition of the engine in the air."

"Any more?"

"Nothing."

Xu Cang replied, then glanced at the cockpit altimeter.

It's just that suddenly, the pointer of the cockpit altimeter turned rapidly, almost directly increasing to nearly [-] feet within two or three seconds.

"Huh?" Richard also saw the change of the cockpit altimeter: "Is this broken?"

The plane was clearly descending, why did the index of the cockpit altimeter increase so much all of a sudden?

If the cockpit altimeter is also broken, it will be a little more troublesome for the altitude reference later.

"No!" Xu Cang's face was solemn, and he couldn't help but clenched the side stick tightly: "It's because the surrounding air pressure is decreasing."

"What?" Richard looked at Xu Cang inexplicably, but soon he realized what Xu Cang meant: "Going in!"

As Richard's voice fell, the plane suddenly stopped turning, even at this moment Xu Cang was actually still manipulating the side stick.

Xu Cang's heart trembled: "Here we come!"

Then, under the action of inertia, the plane flew forward for a short distance, and then swooped straight down like a deflated ball.

Almost at the same time, Richard only felt an indescribable pain all over his body, and his eardrums felt extremely painful as if a needle had been pricked, followed by violent breathing, and he even felt that his eyeballs were swollen. It's about to pop out.

"Come on, come on, go in, vacuum!"

In the center of the huge cyclone, the darkness that seemed to devour everything swallowed the CS300 alive like a huge mouth.Under the traction of the extremely strong airflow on the periphery, a vacuum-like environment is formed in the central area. Once the plane enters, without the lift generated by the air on the wings, it will be an iron lump. It cannot even glide, it will just stand straight fall down.

Since there is almost no air flowing through the wing surface, and naturally there is no rudder surface effect, Xu Cang's manipulation is meaningless.The plane almost rolled over and went into a dive, heading straight for the ground at an angle of nearly ninety degrees.

On the engine instrument data, the engine speed began to fluctuate continuously, and the exhaust temperature also increased intermittently.

"The plane is going to surge!" Richard yelled.

However, due to the thin surrounding air and lack of media, Xu Cang actually couldn't hear clearly.However, this kind of thing does not need Richard to remind, Xu Cang has already discovered the abnormality of the engine.

Contrary to what Xu Cang expected, after entering the near-vacuum environment here, the PW6000 did not turn off directly, but surged first.This is because in thin air, even with the action of the compressor, continuous high-pressure air cannot be produced, so the intermittent air will easily block the airway, resulting in surge.

However, this also reflects from the side that the performance of the PW6000 is really extremely powerful.

Still struggling a little in a near-vacuum environment.

It was a bit different from the plan, and Xu Cang couldn't let it surge, too severe surge would damage the engine, and it would be troublesome to restart it later.Therefore, without hesitation, Xu Cang directly and decisively cut off the engine manually.

"Listen to my password!" Xu Cang shouted suddenly.

The speed of this downstroke was too fast, too fast, and thousands of feet were lost almost in an instant.

However, as the altitude of the aircraft decreased rapidly, the surrounding air content began to increase, and the aircraft showed some signs of autonomous head-up due to its stability in pitch.

At this time, it is impossible for Xu Cang to really raise the plane's head, otherwise the plane will rush into the cyclone again soon.

However, the tendency of the plane to dive is too strong, relying on the pitching stability of the plane alone is unable to suppress it by raising the head independently. Xu Cang only needs to push down the stick slightly, not too much.

"The airspeed indicator seems to be fine!" At this moment, Richard's roar came from next to his ear: "Look!"

Xu Cang immediately set his sights on the airspeed gauges. Sure enough, the airspeed gauges on both sides were already consistent at this time, and both pointed to an airspeed of 380 knots, which was still increasing.

In addition, not only the airspeed indicator, but also the altimeter, which was originally reset to zero, is also increasing its value, and it seems that it will return to normal.

The plane dived too fast, and the friction of the airflow generated heat on the fuselage, which melted the ice that had blocked the probe.

Everything seems to be getting better, and now it depends on whether the fuselage of AVIC can withstand the super high speed.

The exponential increase of the airspeed indicator was so fast that after Xu Cang glanced at the altimeter, the value had already reached 420 knots.At such a high speed, the fuselage of the aircraft has already begun to shake, like porcelain that is about to be shattered at any time.

"It's almost there." This thought came to Xu Cang's mind, and he was about to act.

However, at this moment, the airspeed value, which had already been stabilized, suddenly went up like crazy. Before Xu Cang figured out what the problem was, it had already reached 440 knots.

And Richard next to him also realized the abnormality of the plane, and suddenly exclaimed: "No, no, no! It shouldn't be like this, too fast, too fast, the plane fell too fast, something happened, Xu Cang !"
