When Qitai was still in the afternoon, Derbyshire, England, thousands of miles away, was still shining with the soft yet cool sunshine of the early morning.

In the Rolls-Royce engine test plant, an engine is hanging quietly in the air. This engine does not have any cover, and its components are clearly visible, showing the outside world the brilliance of the essence of artificial industry.

Not far from the engine, there were three figures, and their eyes fell on the engine body.

"Is this the prototype of the Trent 1000?" It was Song Xinyang who spoke.

Half a body ahead of Song Xinyang stood an extremely tall blond man with blue eyes. He was the chief engineer of Rolls-Royce Aerospace Engine Department, Joe.

"Song, it's still a little bit off. It needs a period of debugging to at least ensure the safety of this engine under normal circumstances."

Unexpectedly, this person also spoke Chinese, but his accent was quite obvious. For example, the word Song sounded a bit like Xiu, but he was probably able to communicate.

"Qiao, your Chinese has improved very quickly recently." Song Xinyang said with a smile: "If it's just for communication, it's almost enough."

Qiao laughed: "It seems that I will use this language in the future. It is always right to learn it, and it can also be used as a small hobby to pass the time. I heard that Chinese poetry is very interesting. When I learn it well, you have to teach it.

My poetry in Chinese.”

However, Song Xinyang looked a little embarrassed when he heard this. Qiao saw Song Xinyang's expression and instantly understood: "I forgot that you grew up here. It seems that I have to ask Yang."

As he said that, he patted Yang Tian, ​​who was slightly reserved behind him.

In front of Qiao and Song Xinyang, Yang Tian acted very reserved. When Qiao patted him on the shoulder, his whole body was tense.

Song Xinyang waved his hand: "Qiao, let's talk about the Trent 1000 first. How long will it take for it to be debugged? I have to inform Xu Cang in advance."

"It's hard to say, at least two months."

"Two months, is it so long?" Song Xinyang obviously underestimated the debugging time. In his estimate, he thought debugging could be completed in one month.

Qiao obviously saw Song Xinyang's disappointment: "Why, you still think two months is too long? I have made a conservative estimate, it will probably take more than two months."

Song Xinyang sighed: "We are very passive now. We can grab as much time as we can. I can't help it if I am in a hurry."

"Didn't I just say? At least debug it until there is no problem under normal circumstances. Didn't the Xu Cang you mentioned say that he will only participate in a real-machine test? You can't let him test it without doing a trial project.

Is there something wrong with the engine? Isn’t that a wasted opportunity?”

The Trent 1000 did not even have a prototype before. In order to allow Xu Cang to conduct actual testing, the Rolls-Royce headquarters began to work hard to produce a prototype of the Trent 1000.

However, Xu Cang only promised one chance, so Luoluo headquarters naturally had to be cautious.

Song Xinyang heard some questions: "Under normal circumstances, what about abnormal situations? If the prototype is tested, there is a high probability that there will be problems, right?"

"Who said it's a high probability?" Qiao asked.

"Huh? Isn't it? The prototype performs so well."

Qiao laughed: "It's not a high probability, it's certain, something will definitely go wrong. I haven't seen the Xu Cang you mentioned, but from what I know, but from what I know now, it's really powerful.

But it’s not that bad, right?”

Qiao saw some information about Xu Cang's handling of special situations. He couldn't fly himself, but his eyesight was very strong and he could understand who was good at flying. He admitted that Xu Cang was very strong, but he was not good enough to fly.

Trent 1,000 was bet on this guy.

You know, if something happens, not only the Trent 1000 prototype will be scrapped, but also the Airbus 330 that was used as a test aircraft will have to be accounted for. The direct losses will already be considerable.

Not to mention, if the news that the Trent 1000 test failed gets out, it will have an extremely negative impact on the company's stock price.

From the perspective of Chief Engineer Qiao, he actually feels that the headquarter’s push for the actual testing of the Trent 1000 is somewhat desperate, and he actually doesn’t really agree with it.

"Look at this." Song Xinyang took out his mobile phone, clicked on it a few times, clicked on a video, and handed it to Qiao: "This is an internal video. It shows Xu Cang landing at a mountainous airport. At that time

One engine stalled and the other surged severely."

"What?" Joe took the phone, watched all the more than one minute video on the phone, and finally exclaimed: "Holy Fuck! How the fuck did he do that?"

As the words came out, Qiao felt a little rude in his words: "Sorry, I got a little excited. This is Xu Cang's doing, which is indeed enough for the headquarters to bet on him."

Sure enough, no matter who you are, no matter which country you are in, or which language you speak, as long as you know Xu Cang's landing in Yulong, you can only be amazed.

Qiao returned the phone to Song Xinyang. It seemed that the lingering charm was still lingering. The landing was indeed something to be savored carefully.

"It's not just because they saw this video that they decided to take a gamble. Xu Cang's value has been initially verified. At least Boeing intends to hire him as chief technology officer." Song Xinyang put his phone back in his pocket: "For Boeing

We can still trust his vision."

Qiao smiled and said, "But now I'm afraid the two sides can't get together."

"How do you say that?" Song Xinyang's information channels were obviously updated slowly.

"A few days ago, a research report was published in the circle, which pointed out that there are problems with the structural strength of the fuselage of the 737 series aircraft. The arguments included a large number of references to the special situation Xu Cang encountered at Jianchuan Airport, and the content was quoted in quite detail. I

I guess Boeing must doubt whether Xu Cang provided a lot of information. There may be no evidence, but the suspicion is definitely indispensable. Once the seeds of doubt are planted, it will be difficult to eliminate." Qiao stretched himself: "So

Ah, it would be great if the two sides can maintain peace in terms of performance, but it is impossible to be the chief technology officer."

Song Xinyang has been coordinating the affairs of Trent 1000 recently, and really doesn't pay much attention to external matters: "That is actually a good thing for us."

"Yes!" Qiao shrugged: "My friend at Airbus told me that representatives from General Motors and Lockheed Martin approached the leadership of Airbus headquarters and requested that Xu Cang's Spring and Summer Airlines be banned. It seems that

Not only Boeing, General Motors and Lockheed Martin are also interested in Xu Cang."

Song Xinyang's eyes widened: "It's so good. Doesn't this prove Xu Cang's worth? But, what do GM and Lockheed Martin want from Xu Cang?"

"General's GENX engine and the ramjet engine of Lockheed Martin's HAWC project both require a reliable tester, maybe for this reason." Seeing his opponent in a hurry, Qiao felt quite comfortable: "Tsk, tsk, it doesn't seem to be the case.

It's just that we are the ants on the hot pot. Hey, this slang is used well."

Qiao seemed to be in a good mood: "Song, if this test of Trent 1000 is really effective, then we can use this to launch a more comprehensive cooperation with Xu Cang."

"Humph, isn't it true that even the three-rotor and other technologies were given to him, and even the distribution rights in the Asia-Pacific region were given away, is it not considered cooperation?" Song Xinyang was very dissatisfied.

Technology transfer aside, it has little to do with him. However, the Asia-Pacific distribution rights are an important weight in his hands, and he can exchange them for huge profits. As a result, they were directly given to Xu Cang, and Song Xinyang suffered a lot of losses.

"No, this is not enough." Qiao patted Song Xinyang on the shoulder: "I learn Chinese because I know that the Chinese market will become an extremely important part of the world's civil aviation map in the future. Our allies may be born there. GM

He Puhui is too strong now, and we must have an ally to share the pressure for us. This ally can't be too strong, nor too weak. I think Xu Cang is just right. However, the premise of everything is that he can use Trent 1000 to

Prove your worth."

Song Xinyang felt a little shocked, but considering that although GM and Pratt & Whitney were in competition, they shared a common hostility towards Luo Luo, and the pressure Luo Luo was under was indeed too great.

China has a huge market and a relatively strong willingness to conduct self-research, so it would be best to support a relatively strong local aerospace enterprise that relies on Rolls-Royce to some extent.

Firstly, it can share firepower with Luo Luo. Secondly, it can use this as a breakthrough point to gain more access to the Chinese market. Thirdly, it can also win Xu Cang's favor and deepen the subsequent cooperation between the two. There are indeed many benefits.

However, as Qiao said, the premise of everything is that Xu Cang can pass the Trent 1000 test.

In the sky near Qitai Airport, a plane painted mainly in white passed through the canyon, and was currently flying through the canyon back to Qitai Airport.

"Xu Cang, how did you accomplish it? On the radar screen, your signal point is almost motionless." Now that the most difficult level has passed, the entire control room is filled with joy.

Wang Li even chatted with Xu Cang on the radio frequency.

Xu Cang was in a good mood at the moment. During the operation just now, the palm of his right hand holding the steering wheel was completely sweaty. Theoretically, it is possible to increase thrust, use strong headwinds, and delay airflow separation through the leading edge device.

This greatly delays the actual triggering time of stall.

But theory is just theory after all. Fighters can test on the edge of stalling from time to time. After all, maneuverability is not on the same level at all, but who would do that with a passenger plane?

Even Xu Cang would not casually perform a stall maneuver on a passenger aircraft. In fact, even if Xu Cang wanted to, he would not be able to do it in most cases. When the elevation angle of a large passenger aircraft reaches a certain level, the nose of the aircraft will

It will nose dive due to loss of lift, and it is impossible to bring it to the exaggerated situation Xu Cang just did.

It can only be said that just now Xu Cang had the right time, right place, right people, and extremely precise operations to complete this astonishing mid-air maneuver with no radius.

Chen Guoli was making some simple approach preparations on the side, but he couldn't help smiling. Although Xu Cang did this, as long as he participated, he would get a lot of credit. He is in the sky

China Eastern Airlines has reached its peak, and there is no need for personal benefits. Just being lucky enough to participate in such a major event, Chen Guoli feels that the value of his life has risen to a big level.

Flying in the opposite direction along the single-engine procedure is definitely not allowed under normal circumstances, but we have to follow the emergency and have nothing to do with it. However, at this time, the aircraft must still strictly follow the single-engine procedure route and abide by the

Relevant height restrictions.

The only good thing is that as long as the initial climb gradient of the program does not exceed 5.2%, there will be no problem in descending at the most standard three-degree glide angle.

Of course, if the single-engine procedure can set the initial climb gradient to more than 5.2%, the authority will probably not approve it. The initial climb gradient of 5.2% is quite difficult for a single-engine aircraft, unless it is completely empty.

s plane.

However, in actual operation, apart from adjusting the aircraft, how many of them can fly without a load?

You must know that a gradient of 5.2% almost requires an ascent rate of 800 feet per minute, which is really difficult given the common single-shot ascent rate of 500 feet per minute.

Fortunately, there are no extreme situations, and the follow-up is relatively easy. Because Xu Cang's preset glide path is the most standard three-degree glide angle and 5.2% glide gradient, which can just cover the trajectory of the single-engine program.

That is to say, it is always guaranteed that the aircraft will be above the profile of the single-engine procedure.

In this way, vertical separation on the terrain can theoretically be guaranteed at all times.

However, after all, this is not a real approach procedure but a single-engine departure procedure flying in the opposite direction, so it is more likely to cause a terrain warning.

Terrain warning not only depends on the vertical separation between the aircraft and the terrain, but also on the close rate. For example, if the vertical separation between the aircraft and the terrain is one thousand feet, but the aircraft is climbing up, there may not be a terrain warning.

, because the terrain warning system determines that the aircraft's movement trend is to increase the vertical separation.

But if the plane is descending, a warning may be issued. The reason is the opposite of climbing just now.

Therefore, when designing the approach procedure, especially the procedure route for the final landing stage, it is necessary to consider the terrain warning that may be caused by the normal final descent, rather than just ensuring the terrain separation.

Of course, Xu Cang will not care about this later, and may have to manually turn off the terrain warning later to prevent it from affecting some of his mental arithmetic and operations.
