When Chen Geng and his entourage arrived at the engine assembly workshop, several blonde and blue-eyed Rolls-Royce engineers in white coats and hats and masks were leading Chinese engineers to conduct a detailed inspection of the two engines on the bench.

Modern aero engines are actually quite large.

For example, if you look for a picture of the Fokker F100 aircraft, you will think that this engine does not seem to be very big, but when you stand in front of this engine yourself, you will know that this thing is as big as a car: "tay" The bypass ratio of the MK650-8C engine is 3.2, the diameter of the front fan is 1.143 meters, counting the outside casing, the height of the entire engine is about 1.25 meters. Check that the engine can be placed on a special frame, and the height of the engine above the ground is about 30 cm, that is to say, when you stand in front of this engine fan, even if it is a big man like Chen Geng who is 183 cm tall, you will find that this big guy actually reaches the position of your neck.

As for the length of the engine, it's also more than four meters, yes, you don't think it's a big thing in the photo, it's actually a big guy.

Hearing the footsteps behind him, the British engineer led by him looked up quite unhappily, but when he saw Chen Geng walking at the front of the crowd, he was stunned for a moment, and hurriedly touched the colleague next to him, and the colleague hurriedly greeted him: "Mr. Fernandez, are you here?"

What kind of arrogant prince in white and the like, it doesn't exist, the other party knows Chen Geng's identity and wealth very well, although even if he offends Chen Geng, it doesn't seem to have any impact on him, but ......

Why bother?

I'm not sick in the head, why do I have to go to a super-rich man with a lot of money, but what good is it for me to really annoy the other party?

In these days, there are no real fools.

Chen Geng was also very happy to see the person coming, and he greeted the other party with a smile: "Mr. Johnson, hello, how is it, is your work and life going well?

Johnson is the technical director of Rolls-Royce stationed in the Chengdu hair plant, and he is also the technical master of Rolls-Royce, before determining the candidate for the technical director of Rolls-Royce in China, Chen Geng contacted a number of technical experts recommended by Rolls-Royce, and finally determined that it was Johnson, who was naturally deeply impressed by him.

"Very good," Johnson said, nodding his head repeatedly, "I'm enjoying my life here, especially the food...... God, I never knew there were so many delicious things in the world!"

Speaking of the food in the Bashu region, Johnson made an extremely exaggerated expression: "And it's unbelievable that there are so many different ways to make the same ingredient! I love this country to death, Chen, do you know? Since my wife came to China once at my suggestion, every month when I want to return to China, Anne will not allow me to go back to England, she wants to bring her children to Rongcheng, in order to satisfy the mouth that has been fed by Chinese food." ”

Of course, the travel expenses required by Johnson and Mrs. Johnson to visit relatives every month are borne by Huaxia Commercial Aircraft Manufacturing Industry Group, but this is not the point, the point is that Chen Geng was very happy to hear Johnson say this: "Ha...... If you like it, well, I'll say hello to my friends in Rongcheng and ask them to take you to eat all the streets and alleys of Rongcheng, Johnson, let me tell you, in fact, it's not only in big restaurants that there are delicious things, and some small alleys also hide unexpected food. ”

Johnson's saliva was about to run down when he listened, and he nodded repeatedly: "God! ”

Chen Geng laughed.

Johnson, on the other hand, suddenly gritted his teeth and said to Chen Geng: "Chen, I have already decided, after I help you master the production technology of MK650, I will continue to stay and help you master the 'tay' or improved technology stipulated in the contract." ”

"Is it? That's great," Johnson's answer really surprised and delighted Chen Geng, Chen Geng had sent invitations to Johnson several times, but he never said anything, but he didn't expect to agree today because of the food, Chen Geng immediately said: "In this way, Johnson, you ask everyone how many are willing to stay, if there are many people, I will arrange my plane to transport you back to China every month."

Well, or I bring your family to Huaxia to reunite with you, no problem, in short, whether you go back to the UK, or your family comes to Huaxia, I will be responsible for the pick-up. ”

Johnson's attainments and level in aero engines, even in Rolls-Royce, can be ranked in the top five, if Johnson is willing to take the initiative to stay, there is such a know-how of technology, for the Huaxia Commercial Aircraft Manufacturing Industry Group, which has just taken the first step in aero engines, it is really not much different from pie in the sky.

Johnson knew Chen Geng's McDonnell Douglas MD-82 private jet, when they came to China, in order to show the importance of themselves and others, Chen Geng sent his McDonnell Douglas -82 to bring everyone from England to Huaxia, after a large jet private jet, Johnson had a feeling: no civil aircraft, even a comfortable first class, can not be compared with Chen Geng's private jet that can only be described as luxurious.

Johnson, of course, was very happy with such a benefit, and he asked in a loud voice: "Everyone heard it?" ”

After speaking, Johnson suddenly patted his head: "Oh, by the way, I haven't congratulated you yet." ”

"Oh?"

Chen Geng didn't react for a while: Congratulations to yourself? Congratulations to what?

"In your first year in the WRC, you can achieve the fifth place in the team and the fourth place in the drivers' place" Johnson gave a thumbs up: "Chen, you guys, very good, very good!"

That's what I said.

Chen Geng suddenly realized.

The two chatted for a few words, and without waiting for Chen Geng to ask, Johnson took the initiative to introduce the two "tay" MK650-8C engines on the bench to Chen Geng: "These two engines have completed the cold start, the results of the cold start are very satisfactory, and the operation between the various components is within the specified range. ”

Chen Geng nodded again and again.

The so-called cold start, in fact, is to make the engine run passively through the external power system, the purpose is mainly to check whether the lubrication, adaptability and assembly accuracy between the various parts of the engine are within the required range, that is, the purpose is to check whether the engine has problems in the assembly angle.

Cold start is also the first test link after the completion of an engine assembly, only the cold start link has no problem, the engine is not ignition, no fuel injection in the case of the run-in and lubrication between the various components is good, the oil circuit, lubricating oil system everything is normal, and then the ignition start test will be carried out.

However, compared with the "tay" MK650-8C, which has completed the cold start test, Chen Geng is more concerned about another thing: "Johnson, how long will it take for the MK650 to complete the modification of the digital control system?"

Like the "Spey" MK202 introduced by the state in previous years, the control system of the "tay" MK650-8C is also mechanically hydraulic.

The so-called mechanical hydraulic control system, to give a not very accurate, but in fact similar example: this thing is actually similar to the common carburetor on our motorcycle, but the motorcycle is controlled by pulling the throttle to the carburetor, and the aircraft is special, the distance from the cockpit to the engine is too far, and it is more labor-saving to control it with a hydraulic system.

For automobiles and motorcycles, the same engine, after being equipped with a carburetor, the fuel consumption will be higher, and the power performance will be worse, because the carburetor cannot accurately control the oil, and there is no way to inject fuel independently according to the load of the engine and the slope information of the current road given by the slope sensor, so the EFI has gradually become a development trend.

The same is true for aero engines, which are equipped with mechanical and hydraulic control systems that cannot be compared with digital control systems in terms of power response and fuel consumption.

When Chen Geng introduced the "tay" MK650-8C, he introduced the full digital control system of Rolls-Royce in the name of "accessory upgrade" to upgrade the control system of the "tay" MK650-8C.

"If all goes well, four months is enough," Johnson said confidently, "it's just about debugging and matching, it's not that difficult." ”

The surrounding Chinese engineers suddenly smiled wryly: It is not difficult for you, it is not difficult for you to be a leader, but for us...... Hey, to put it mildly, a lot of people haven't even heard of a full-power digital control system before.

Just four months?

Chen Geng smiled and nodded.

"Mr. Johnson," said a foreigner in a white lab coat with a folder, "all the projects and subsystems have been checked, and there are no problems." ”

As he spoke, he handed the folder to Johnson.

After speaking, he nodded to Chen Geng: "Hello, Mr. Fernandez." ”

"Hello, Mr. Wayne. Chen Geng nodded to the other party.

"Well, it's really no problem," after following the inspection items on the folder one by one, and after making sure that all the systems were normal, Johnson breathed a sigh of relief and said happily to Chen Geng: "Mr. Fernandez, congratulations, tomorrow you will be able to see the first ignition test of MK650." ”

Chen Geng smiled: "It seems that I am lucky." ”
