With Jindal's previous experience, no one dares to race against time anymore, and stability is the first priority!

With this in mind, it took them half an hour to finally put all the powder on the mold, a total of four blisks, two turbine blisks, and two compressor blisks.

Modern engines are axial-flow, with fan blades tightly arranged, and the air flow agitated by the front blade blows onto the back blade to pressurize the air, and the back is to receive the energy of the air flow, which rotates under the blowing of the air flow, that is, the turbine.

The center is the rotating shaft, the outside is the blade, between the rotating shaft and the blade, there needs to be a blisk to connect, the compressor has a compressor blisk, the turbine has a turbine blisk, these devices should be light, but also have high strength, only powder metallurgy technology can achieve.

These four are the four most important blisk blanks on a set of Ruida 800 engines, and with this group, you can bring it back and assemble a Ruida 800 engine! This is the world's most powerful engine, and it's the future of their Rolls-Royce!

"Now start pressurizing!"

The forging hammer of the huge hydraulic press began to descend slowly, and as long as it was pressed against the mold, the huge pressure of 80,000 tons could make all four blades, and then it was put into the electric furnace to be calcined......

Don't worry, two hours is enough!

The hammer comes down, presses onto the die, and then starts pressurizing.

10,000 tons!

20,000 tons!

It has been added to 50,000 tons, which exceeds the pressure of Lao Maozi's die forging press!

"Keep pressurizing!"

"Bang!"

At this moment, suddenly, there was a noise at the nearby grating ground detection port, and the hydraulic oil sprayed up, with strong kinetic energy, and actually lifted up the nearest guy, who was covered in oil and looked embarrassed.

"Quick, turn off the device!"

"Close the valve!"

All kinds of nervous voices sounded, and everyone knew that this was a big trouble!

"Invite the Orientals in at once!" Janet noticed that her voice was a little shaky.

The machine is broken! What to do, what to do?

"It must be that the machinery and equipment of the Oriental people are not qualified!"

"That's right, there's something wrong with their machine! We'll have to get them back our usage fee! "Some people have lost their face.

After receiving the news, Zhou Minghui immediately rushed to the scene with technicians, without saying a word, rolled up his sleeves and did it, they drilled into the ground, found the exploded oil pipe, and then found some powder in this oil pipe.

"Zhou Gong, what caused the failure?" Janet asked nervously.

"It's strange, how can there be powder here?" Zhou Minghui said: "This pipe is connected to a hydraulic oil filter to filter impurities in the hydraulic oil, but we use the best hydraulic oil and never filter out the powder, which may clog the pipeline in the process of flowing, resulting in a burst pipe." ”

Powder!

Hearing Zhou Minghui's words, Jindal's legs trembled, do you need to say anything? It must be that bag of powder of your own! Who would have thought that there was a hydraulic oil filter below, and there was a pressure relief channel on top of this filter, which must have jumped into it in the process of working!

"That, that, then we ......" Janet was incoherent, not knowing what to say.

"We need to overhaul all the pipes and clean up the powder, don't worry, this is an accident, it won't be counted in your rental time, and you can continue to use it when we fix it."

"Uh-huh, so we're here to help?"

"No need, there's oil everywhere here, and it's inconvenient for you. Go and stay in the guest house first, and then we will call you when we have it repaired. How is this gentleman and does he need to go to the hospital? ”

The oil-stained British engineer got up from the ground: "It shouldn't be too much of a problem, I need to go back and take a shower." ”

"Okay, then we'll go first......"

At this time, where did Janet dare to say that the powder fell by herself, and planned to collect all the powder, and could not leave it to the Orientals, if the other party knew, she would definitely ask them to compensate for the loss!

The others didn't dare to speak, and followed Wang Fang to live in the guest house, and even the four blisks pressed on the workbench couldn't be taken away, after all, now that they were pressed, the hydraulic press couldn't move, and the blizzard inside couldn't be taken out.

When the British left, Zhou Minghui took the workers and spent five minutes repairing the pipeline, and then looked at Qin Feng: "Mr. Qin, when are we going to call the British?" ”

"Three days later, don't worry."

"Three days?"

"That's right, let them know that because of their mistakes, it took us three whole days, 800,000 an hour, which is a loss of 50 million or 60 million dollars!" After Qin Feng finished speaking, he looked at the workbench again: "Test these blisks that have been pressed by 50,000 tons of pressure to see how the quality is, and then press some other parts, this time can't be wasted." ”

"Hmm."

That night, Janet lay on the bed in the guest house, tossing and turning, unable to sleep.

The Oriental is so nice! The other party may have guessed that it was their own mistake, but they did not blame themselves!

Do you want to do something to make up for it?

After a sleepless night, Janet woke up with two panda eyes, and then saw Zhao Jiao, who was in charge of receiving them.

"Miss Zhao, what's going on over there?"

"It is being repaired, and I heard that metal powder has entered the hydraulic cylinder, and a trace has been scratched on one of the steel cylinders, and the maintenance plan is currently being determined."

With a pressure of 80,000 tons, a trace may cause pressure relief! This is a serious production accident!

Janet was even more apprehensive.

"Need our help?"

"No, just leave it to them, I'll take you for a walk around Jincheng."

When the day came back, the machine was still not repaired, and after dinner, all the Englishmen gathered in Janet's room.

"We are responsible for this production accident, and until now, the Oriental people still have no intention of blaming us." Janet said: "I thought, we should do something, should we help the Orientals improve the Spey engine? ”

"How is it possible, the engine improvement was made by Allison, although I know how to change it, but I must not say it, otherwise it will be a leak and I will go to jail." Jindal said.

"Jindal, if you hadn't spilled that bag of powder by mistake, there wouldn't have been all this, if the Orientals were to pursue it, they would ask us to compensate tens of millions or even tens of millions, since it was your mistake, then you have to bear part of the compensation, do you have so much money? If you don't have money, don't you still have to go to jail? ”

Kindall stopped talking.

"We used to rebuild the MK205." Another engineer said: "Just modify the fuel supply system, inject more fuel, and increase the turbine front temperature, you can make the afterburner thrust reach 11.3 tons, and this improvement plan can be handed over to the Orientals." ”

"That's right, in this way, they have to use high-temperature turbines, which are not included in the previous technology license, and if you want this level of engine, you have to buy it from our Rolls-Royce company, and we can also bring a business to the company, and the company will definitely be happy!"

They come out for a lot of money, and if they can bring an order back, or exchange it with an Oriental, it will be good for the company.

Janet frowned: "I'm afraid this method won't last long, it's better to increase the diameter of the fan." ”

"Janet, you are our leader, and we have to listen to you, but don't forget, we are from Rolls-Royce, we are here to do business, not to make friends."

Janet's face was ugly and she didn't speak again.

Friends or business, which is more important?

This night, Janet had insomnia again, and the next day, her eyes were red, like rabbits, and Zhao Jiao was very distressed: "Ms. Janet, why did you make yourself like this?" Is it not adaptable? ”

"No, I just didn't get jet lag, how is the machine repaired?"

"I ordered parts from the relevant units, and it will arrive tomorrow at the earliest, and it will be repaired the day after tomorrow."

Three days, you have to delay for three days, how much does it cost!

Dongfang is the best friend, and they value friendship more than business!

Janet's mood was extremely complicated: "Ms. Zhao, we are willing to help. ”

"No, you can't help much, after all, you need to wait for the parts provided by the brother unit now." Zhao Jiao said: "Ms. Janet, didn't you say something about Spey Engine when you came?" Today, I will take you to Factory 430 to have a look, and Mr. Qin will also accompany you. ”

"Hmm." Jenny nodded, her heart full of emotion.

In that year, in order to change the backward situation of Eastern Aero Engine, the state decided to spend a huge amount of money to purchase Spey engine technology from the United Kingdom, but this introduction project was resisted by a large number of people.

The first aero engine factory in the north, 410, is called a dissatisfaction, what is this doing? We obviously have our own Turbofan VI, but you actually want to introduce Spey, we don't agree, this will seriously impact our existing projects!

The maximum afterburner thrust of Spey is less than ten tons, which belongs to the medium thrust, and the maximum thrust of the turbofan six reaches more than twelve tons, which belongs to the large thrust, and these two engines are not at the same level at all, but the 410 factory is extremely disgusted and tries all kinds of ways to resist.

As a result, the superiors could only give up the task of trial production in the 410 factory and handed it over to the 430 factory, and then the facts also proved everything: the turbofan six of the 410 factory, the paper data is very advanced, but it can't get off the test bench at all, no aircraft designer dares to install it on the plane, the turbofan six project was honorably launched, the turbofan ten came up, and it was developed for more than ten years, at most dare to install it on the double-engine J-11, and the single-engine J-10 only dared to continue to use the third uncle.

After more than ten years of tossing in this way, the turbofan ten finally matured, and before that, the only mature engine produced in China was only Spey's domestic turbofan nine! Aero engines involve all aspects of industrial technology, and they cannot be made by shouting a few slogans.

Even if it is a turbofan nine, it has experienced countless twists and turns.

A small passenger plane with twin engines was parked at the airport in Jincheng, and when the British guests came here, they were a little surprised.

"Mr. Qin, I didn't expect you to lease a small passenger plane to us as a special plane." Janet said excitedly, "We'...... Thank you very much. ”

In Europe or the United States, it is very common to go out and take a plane, especially in the United States, there is no advanced rail transportation conditions, but the aviation sector is very developed, even if it is a city a hundred kilometers away, you may choose to fly.

As for the East, railway transport comes first, green leather cars whizz across the land of the motherland, going from south to north, transporting people and materials, more than a hundred kilometers, taking a train is almost the best choice, as for passenger planes? Without a letter of introduction, even if you have money, you can't get up.

Charter, special plane? That's not something that a private enterprise can coordinate.

Qin Feng smiled: "The 430 factory we are going to is a little far, and it will be very uncomfortable to take the train, so we coordinated a special plane to come over, and the space inside is a little small, so everyone will take a look." ”

Qin Feng looked at the passenger plane on the side, on the single wing, which belongs to the facelift of the transport aircraft, the fuselage is small, and it belongs to the single-aisle regional airliner, which is the Yun-7-100 regional airliner that Xifei took the market-oriented route and made out.

Yunqi is an imitation of the old Maozi'an-24 twin-engine pot wheel propeller short- and medium-range transport aircraft, the prototype was only produced twenty, and then it was Yunqi-100, taking the route of civil aviation, changing the transport aircraft into a regional airliner, and produced fifty before and after, and even flew over international routes, but unfortunately the technology is too old, the fuel consumption is high, the failure rate is high, and it was quickly eliminated.

And now, this kind of regional airliner has just been developed and is in the trial operation stage, so Qin Feng said hello to the Air Force, and he coordinated a plane over there, without him spending any money, the routes were specially approved by the Air Force, after all, he was running for the Air Force's Spey engine project!

Although Qin Feng has taken a passenger plane many times, it is the first time for Yun Shi to go up, and like the private jets bought by some celebrities in later generations, this kind of plane is very small, and tall people will even touch their heads, however, the feeling of taking a charter flight is still much cooler than taking a train, the key is to take a charter flight that does not cost money, then it feels even more refreshing.

If you take the railway train, it is estimated that you have to swing all day, the passenger plane flew to the ancient city in two hours, and at 11 o'clock in the morning, you will arrive at the 430 factory, the time is just right, you can eat in the 430 factory, and save a sum of hospitality!

430 Factory Guest House Restaurant.

Li Guofu, the person in charge of the 430 factory, raised his glass: "Come, let us raise a glass together, welcome our British friends, in that year, in order to help us master the production technology of Spey engine, a large number of British consultants came to our factory, working together, happy cooperation......"

"Director Lee, the father of this Mrs. Janet, was Sir Hooke, the head of technology in England at that time." Qin Feng specially reminded.

Li Guofu's eyes lit up instantly: "No wonder you look so similar, Ms. Janet, since you are here this time, you have to stay with us for a while longer!" Let's do our best to be a landlord! ”

"Mr. Li, you can do it." Janet said: "My father came on the basis of a contract we had agreed upon, and they were all paid. ”

If it weren't for the fact that she had experienced too many things on the Jincheng side, Janet would never have been so honest.

"Wages are wages, friendship is friendship, come, let's toast to friendship!"

Janet's heart was so excited that she took a big sip of her red wine glass.

"Director Li, after my father left, how many Spey engines did you produce?" Janet asked.

"Ugh." Li Guofu suddenly sighed.

"What's wrong?"

"In 79 years, we used the blanks provided by the UK to process out four engines, completed a 150-hour long-term test run assessment in our country, completed the high-altitude simulation test in the UK, the start test under minus 40 degrees Celsius and the cyclic fatigue strength test of the five major components, the test results proved that the engine we produced has reached the same level as the UK, and you have withdrawn all the experts in the UK, and then, we used the domestic blank to trial produce the engine, but we failed."

Li Guofu's eyes were full of frustration and defeat, and Qin Feng sighed on the side, Director Li's performance was very similar, not only because of his long-distance phone call, but also because of the outpouring of true emotions.

After repeated negotiations, the contract mainly consisted of three parts: a patent contract for Spey engines of 41.5 million pounds, a sales contract for the whole engine of 30.97 million pounds, and a patent contract for engine auxiliary equipment of 4.325 million pounds, of which the sales contract for the whole engine included 50 new engines, 2 refurbished engines, a complete set of blanks for 10 engines, blanks for five engine auxiliary engines and aircraft accessories, etc.

The goal of the contract at that time was also very clear: within three years, the engine of the same quality as the British would be made from the blanks provided by the United Kingdom, and within five years, the engines would be made from domestic blanks.

However, after the completion of the three-year goal and the completion and acceptance of the first phase of the Spey project at the end of 83, the whole project was stopped, because the state had no money and wanted to engage in economic construction.

Everyone is confused, and if they don't invest now, won't the previous ones be wasted?

The turbofan six on the side of the 410 factory has also proved to be a model product, and now there is no suitable aero engine in China at all! As long as Spey continues to invest, he can be a pillar!

The attitude of the superiors is also firm: Spey is useless!

At the beginning, the introduction of Spey was a pure introduction of engines, and there was no suitable aircraft option at all, and the superiors had to find a way to sell it, and only J H Qi was willing to ask for it.

Although the 430 factory was in a hurry, it was useless, until last month, the relevant departments came with good news: Spey can be used! There is still a lot of use, the fifty units in stock will be used soon, and you have to resume Spey production.

What are you kidding, how to produce? The domestic blank is not qualified!

In the past, the engine was not used, they were in a hurry, but now that the engine is used, they are even more anxious.

At this critical time, Mr. Qin sent charcoal in the snow, and after sighing about this, Li Guofu was waiting for the other party's reply.

Sure enough, it didn't disappoint him.

"If there's anything we can't solve, tell us and we'll be able to help!" Janet knew that the time had come for her to repay Mr. Qin.
