Chapter 508

McDonnell engineer can understand the overbearing words, but the McDonnell technician behind the spirited old mechanic is blind. One of the fat technicians still smiles and gives the old mechanic a thumbs up, and only yells: "good!"

Another wearing a toad mirror is the donkey lip does not talk about the horse mouth about women's topics.

The old mechanic obviously didn't understand what the McDonnell Douglas technicians said. Beating his chest was a kind of boasting. In a word, the two groups of people were chatting happily, but they were not in the same line at all.

McDonnell's engineer was full of black thread. He rubbed some swollen eyebrows with his hands and coughed heavily. The two groups of people who were chatting with each other quickly went along. The two McDonnell's technicians immediately opened their eyes and quickly stepped forward to say hello: "Mr. miles, have you eaten?"

"En ~ ~ eat..." Engineer McDonnell, whose name is miles, stroked the glasses on his nose and nodded. As soon as he wanted to say something, he saw master Ju swaggering up to him: "yo ~ ~ why are you so fresh? Is it the new one to take over? Ha ha, that's good. At least there's a relief in the evening. "

Miles glanced at master Ju and responded in broken Chinese, "what's the point? You mean you want to make fun of me? "

Master Ju's face changed suddenly when he heard that he was just like a cat stepping on its tail. He looked at miles with a surprised look like a monster: "can you speak Chinese?"

"Shanghai stock market Local dialect Yes, it's called vernacular. I know a little bit about it. " Miles explained it seriously.

Master Ju thinks that he has a bad look on his face. He thought he would find another ghost tie Hanhan who can arrange things casually and give him a thumbs up on all kinds of good things. But in the end, he came across a guy who knows Chinese.

Then there was no way to have fun, so the interest of continuing to talk was gone, so he was ready to turn back, but he didn't want to wait for action. Miles asked in Chinese, "what's 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 deep questions directly. He had been busy for nearly four hours, and no one had asked him about the specific parameters of D-25.

It seems that he is still a professional.

Master Ju thought to himself, and then stopped. A proud smile appeared on his honest face: "the maximum power is 252kw, the overhaul interval is 3400 hours, and the service life is 11000 hours. How about that? That's great

After saying this set of data, miles could not help but look surprised, but under the cover of the light, it was not revealed. This set of data is not only powerful, but also powerful enough to explode.

The top Apus of Honeywell, GM and RORO are at this level.

However, this surprise soon faded from miles' face. The reason is very simple. As a rigorous aviation engineer, he believed 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 said, it depends on more systematic test results.

So miles nodded politely: "OK, thank you. I hope we can talk again next time."

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

Just ready to talk about the performance of D-25 inside and outside, master Ju didn't expect that the foreigner with glasses left with a cold word, which made master Ju feel uncomfortable. At the same time, he also thought of his careless daughter-in-law, who was just as cold and impolite, which made master Ju's infinite grievances turn into uncontrollable "Your uncle's!"

“Good！” Fat McDonnell technician quickly connected, wearing a toad mirror, and immediately made a lengthy introduction to the different tastes of girls from different countries.

Master Ju was in a daze, but he thought it was very good, so he swept the two iron Hans in front of him again. He laughed and cried in a loud voice: "your uncle's!"

……

Miles didn't bother to pay attention to the boredom of the people behind him. He took out his papers, crossed the outer blockade line, and then went up the simple spiral staircase to the cabin. As soon as he stepped into the cabin door, the appropriate temperature made miles feel comfortable. He took a deep breath and walked towards the cockpit, even though he saw FOSS and two Chinese people pointing to the numbers on the aircraft's instrument display saying something .

As a result, I suddenly found that Myers, the uninvited guest, and the warm communication between the two sides suddenly stopped. Especially FOSS, his face became very ugly. It was obvious that last night's unhappiness made the sales director of McDonnell Douglas unable to let go.

After all, Myers was on his side, so FOSS adjusted his mood and was about to introduce the two Chinese partners around him with his nose in his hand. However, he heard Myers speak first: "I'm sorry, Mr. FOSS, my idea yesterday seems to be wrong. Before boarding, I already saw that the DC-10's power, ventilation and hydraulic system are working well without starting three main engines The signal, everything is working.

This proves that China's APU has successfully connected to our backup control system. To be honest, it surprised me, but it also made me very happy, because it is equivalent to the realization of three sets of DC-10 operation control systems, which is very good news for the MD-11 under development. "FOSS was stunned when he heard the speech. He didn't expect that miles, who had always been arrogant, would solemnly apologize to him in front of outsiders. What's more, he didn't expect that people would tell him all the things they had done in the past four hours through observation.

But think about it. Although Myers is not as senior as himself, as the most senior aviation engineer of McDonnell Douglas, his ability is beyond doubt. What's more, the proposer of the improved DC-10 and the three groups of safety backup aircraft control devices of MD-11 wide body airliner based on it is this Mr. Myers.

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

It is generally believed that the more backup systems on the aircraft, the higher the safety of the aircraft.

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

The previous DC-10 is this model. However, due to the bad reputation of DC-10, McDonnell Douglas company hopes to focus on security in the next generation of MD-11 in order to regain its reputation and win customers again. Therefore, it adds a set of backup system in the design and realizes three sets of operating system architecture.

Unfortunately, McDonnell's idea is very good, but the power of the APU they are equipped with is not enough to meet the connection of the full set of backup system. They can only cooperate with the battery to set up the second set of backup system, which does not fulfill the original intention of the three systems.

After the successful installation of D-25 produced by Tengfei Aviation Corporation, with its stable output of 252kw, the improved DC-10 with reserved interface completely got rid of the shackles of battery and independently supported the second backup system. In addition to another backup system with battery as the core power source, the improved DC-10 finally completed the configuration of three systems.

So FOSS's face finally softened, showing a warm smile: "the good news is more than that, listen to Zhuang's next words, I believe it will make you startled."
