McDonnell Douglas engineers could understand this domineering remark to some extent, but McDonnell Douglas technicians who followed the energetic old mechanic were blind, and one of the chubby technicians smiled and gave a thumbs up to the old mechanic, only shouting: "Good!"

Another wearing toad glasses is a donkey's lips and a horse's mouth, talking about women.

The old mechanic obviously didn't understand what the McDonnell Douglas technicians were talking about, and he beat his chest, which was a bit of boasting, and all in all, the two groups of people looked at the conversation and chatted very lively, but in fact they were not on the same line at all.

McDonnell Douglas engineers were full of black lines, rubbed their somewhat swollen eyebrows with their hands, coughed heavily, and the two groups of people who were chatting enthusiastically hurriedly followed the prestige, and the two McDonnell Douglas technicians immediately opened their eyes wide, and hurriedly stepped forward to say hello: "Mr. Myers, have you eaten?"

"Well~~ ate ......" McDonnell Douglas engineer named Miles stroked the glasses on the bridge of his nose, nodded, and just wanted to say something, he saw Master Ju swaggering over: "Yo~~ Why are you so raw? Is it a new successor? Haha, that's good, at least there is a boredevil." ”

Miles glanced at Master Ju and responded in broken Chinese, "Relieve boredom?" do you mean you want to joke with me?"

When Master Ju heard this, his expression changed suddenly like a cat that had stepped on his tail, and he immediately looked at Miles with a surprised gaze like a monster: "Can you speak Chinese?"

"The ...... of the Shanghai Stock Exchange Local vernacular...... Yes, it's called local dialect, and it will be a little bit. Miles explained earnestly.

Master Ju felt a bad face, thinking that he would find another ghost guy who could arrange casually and give himself a thumbs up for all kinds of Good, but he met someone who understood Chinese.

Then there was no way to have all kinds of amusement, so the interest in continuing to talk was gone, so I was ready to turn back, but I didn't want to wait for action, so I heard Miles ask in skimming Chinese: "What is the maximum power of your D-25? What is the overhaul interval? What is the service life?"

Master Ju didn't expect Miles to ask such an in-depth question directly, and no one asked him about the specific parameters of D-25 after he was busy for almost four hours.

Seems to be a knowledgeable person.

Master Ju thought to himself, then stopped his movements, and a proud smile appeared on his honest face: "The maximum power is 252 kilowatts, the overhaul interval is 3,400 hours, and the service life is 11,000 hours, how about it?"

After saying this set of data, Miles couldn't help but be shocked, but under the cover of the lights, it was not revealed, this set of data is not only powerful, it is simply so powerful that it is good.

Honeywell, GM, Rolls-Royce's top-of-the-line APUs are also at this level.

However, this surprise quickly receded from Miles's face, the reason is very simple, as a rigorous aeronautical engineer, he believes in real test data rather than beautiful numbers on paper, so he was surprised, as for whether the D-25 can really be as the old mechanic in front of him said, it depends on the more systematic test results.

So Miles nodded politely: "Okay, thank you, I hope we talk again next time." ”

With that, he raised his legs and walked towards the brightly lit DC-10 at a faster speed.

Master Ju, who was just about to talk about the performance of D-25 inside and out, didn't expect the foreigner with glasses to coldly drop a sentence and leave, which made Master Ju feel uncomfortable at the same time, but also remembered the unconscious daughter-in-law at home, the same cold, the same impolite, so that Master Ju's infinite grievances finally turned into an irrepressible sentence: "Your uncle!"

"Good!" the chubby McDonnell Douglas technician hurriedly picked up, and immediately introduced the different tastes of girls from various countries in a long speech wearing a toad glass.

Master Ju was stunned for a little dazed, but he thought it was good, so he swept the two Tie Hanhan in front of him again, laughed, and shouted in a high-pitched voice: "Your uncle!"

......

Miles didn't bother to pay attention to the boredom of the few people behind him, took out his documents, crossed the outer blockade, and then went up the cabin along the simple spiral staircase, just stepped into the cabin door, the right temperature made Miles feel comfortable all over, took a deep breath and walked towards the cockpit, and then saw Fox and two Chinese pointing to the numbers on the aircraft instrument display and saying something.

As a result, it was suddenly discovered that Miles was an uninvited guest, and the warm communication between the two sides came to an abrupt end, especially Fox, whose face became ugly, obviously last night's unhappiness made the sales director of McDonnell Douglas unable to let go.

But Miles is from his side after all, so Fosss adjusted his mood, and was about to pinch his nose to introduce the two Chinese partners around him, but heard Miles speak first: "I'm sorry Mr. Foss, my idea yesterday seems to be wrong, I have seen before boarding the plane, without starting the three main engines, the DC-10's electricity, ventilation, hydraulics, signals, etc. are all working normally."

This proves that China's APU has successfully connected to our backup control system, to be honest, this surprised me, but it also made me very happy, because this is equivalent to the realization of DC-10 three sets of operation control system, which is tantamount to great news for the MD-11 under development. ”

Fox was stunned for a moment when he heard this, he didn't expect that Miles, who had always been arrogant, would solemnly apologize to him in front of outsiders, and he didn't expect that people would tell him everything they had done in the past four hours through observation.

But think about it, although Myers is not as high as his own position, as the most senior aeronautical engineer of McDonnell Douglas, his ability is naturally undoubted, not to mention that the proposed of the three sets of safety backup aircraft control devices of the improved DC-10 and the MD-11 wide-body passenger aircraft developed on the basis of it is this Mr. Miles.

The so-called aircraft safety backup system refers to the ability of the aircraft to switch the backup system to continue to control the normal operation of each subsystem of the aircraft in the event of an emergency, the original control system fails.

It is generally believed that the more backup systems there are on an aircraft, the more secure the aircraft will be.

The problem is that the backup system also occupies space and increases the total amount of structure, so it is unrealistic to set too much, so there are only two sets of general aircraft, one is the normal control system, and the other is the backup system.

The previous DC-10 was this model, but due to the bad reputation of the DC-10, McDonnell Douglas wanted to focus on security on the next-generation MD-11 in order to save its reputation and win customers again, so it added a backup system to the design to realize the architecture of three control systems.

It's a pity that McDonnell Douglas's idea is very good, but the power of the APU they are equipped with is insufficient, and it cannot meet the connection of the full backup system, so it can only cooperate with the battery to realize the setting of the second backup system, which does not complete the original intention of the original three systems.

It was not until the successful installation of the D-25 produced by Tengfei Aviation Corporation that the improved DC-10 with its stable output of 252 kilowatts completely got rid of the shackles of the battery and independently supported the second backup system.

So Fox's face finally softened, revealing a warm smile: "The good news is more than that, listen to Zhuang's next words, I believe it will surprise you." ”
