Chapter 1225 The British’s doubts
Due to time differences and distance, China often receives news from Europe and the United States slightly slower than the UK.
In the evening of the same day, Beijing time, Chang Haonan was looking at the computer, checking the decision-making plan for the advanced verification of the elastic power system that had just been sent from the Sixth Aerospace Institute.
After all, it is a test equipment that relies on mature technology as much as possible. It was not intended to be finalized from the beginning. Therefore, whether it is a warhead, guidance system, control system or power system, the test process is fast and simple while ensuring basic reliability. .
Including the name YF76, it was actually given by the Sixth Academy themselves.
After more than half a year of high-frequency testing, this low-temperature liquid rocket engine has now reached the condition where it can be loaded.
As long as we conduct a few more joint exercises with the rocket body part to confirm that there are no problems with the balance of the missile itself, we can officially start the production process of the verification missile.
If the Haofei Group modifies the Tu-160 quickly enough, it may be able to complete the first test before next spring.
Of course, according to the plan, it was also the only test.
After the JF14 wind tunnel is completed, the main attention will be devoted to the two truly black technologies of waverider and scramjet engine.
As for the results of this verification bomb, it will probably be used to develop a solid-fueled double-cone missile with actual combat value.
Thinking of this, Chang Haonan couldn't help but smile.
The idea of "magnetic fluid power generation" in my mind is getting more and more exciting.
It has been nearly ten years since he was reborn.
However, limited by various subjective and objective factors, most of the projects completed during this period can only be regarded as making up for the regrets of the previous life.
That is to say, using the experience of the previous life, many key nodes have been advanced for a period of time.
But now, he finally has some free time and resources to develop some truly black technology that he has never seen in his previous life...
Just when Chang Haonan was immersed in the beautiful vision he had outlined, a hurried knock on the door outside interrupted his thoughts.
To make it easier for technicians to come in and out, his office is rarely closed.
So when he looked up, he could see Ren Bingda standing outside the door.
Chang Haonan immediately signaled the other party to come in.
Ren Bingda walked like wind, opened the folder under his arm, turned it 180°, and placed it on his desk:
"Mr. Chang, the latest situation just confirmed is that MTU has announced that it will cooperate with Pratt & Whitney to develop a new generation of civil aviation power, which is planned to be used in a new generation of large regional and single-aisle medium-sized mainline passenger aircraft. The level should be the same as our AE1500. All overlap. ”
Chang Haonan's right hand, which was sliding the mouse flexibly, suddenly stopped.
The smile on his face also disappeared.
He quickly picked up the folder and scanned the contents quickly.
"PW1200 and PW1500..."
"The entire project is expected to be completed in four phases..."
"Gear drive, counter-rotating turbofan..."
When he saw the end, Chang Haonan couldn't hold back at all:
"Why do you also want to build a cold-recuperation turbofan engine...or go with Pratt & Whitney?"
There has been cooperation between MTU and Pratt & Whitney, and he knew about it.
Including the PW1000G engine previously designed for the Airbus A318 passenger aircraft, many of MTU's unique technologies were also used.
But it's one thing to use each other's technology, it's another thing to directly declare that we are in the same camp.
Even for him, this was a complete departure from his initial expectations.
Fortunately, it deviated in a favorable direction.
So this news only brings surprise, not shock——
In fact, the reason why the AE1500 project has been rushing to progress, and even did not hesitate to use "leak" means to let the British know the truth, is largely to prevent MTU from colluding with Rolls-Royce before itself.
After all, in the original timeline, it was the latter that acquired MTU's parent company in the end.
But now it seems that a wrong mindset has been made.
Before the financial crisis that swept the world in 2008, the Germans were not necessarily willing to get too close to the British.
As for inclusiveness...
Although it is nominally a Canadian company, the environment in North America can only be said to be understood by everyone. Canada's independence is to some extent even inferior to Japan and South Korea.
Therefore, Chang Haonan was not included in the list of candidates from the beginning.
In the last life, China was forced to deal with Pratt & Whitney for many years because it had to import a lot of turboshaft/turboprop power from the other side.
There is no such concern now.
His goal has always been to tie up Europe and deal with North America.
"I never expected that the companies that formed the International Aero Engine Corporation back then would have no psychological burden at all selling their teammates... In this situation now, Luo Luo will definitely feel a full sense of crisis."
Chang Haonan sighed with half emotion and half sarcasm: "My original plan was to use the opportunity of the Rolls-Royce delegation's visit to China last month to reveal some key information, and then let them buffer it for a few months until next year. At the Singapore Air Show, we will confirm the news that we have intercooling and reheating technology. This step-by-step approach will make it easier for the British to accept it.”
"Who would have thought that this German helped us a lot and saved us all these steps..."
In fact, what Chang Haonan didn't know was that the Germans inadvertently gave more than just assists.
Without the sudden official announcement from MTU and Pratt & Whitney, Rolls-Royce was likely to have been misled by insiders and refused to believe in the possibility of applying intercooled heat recovery technology to the aero-engine field.
Although you will definitely get slapped in the face in the end, going back and forth will inevitably waste time.
"Then our plan must be adjusted accordingly?"
Ren Bingda asked cautiously.
"Well..."
Chang Haonan pondered for a moment:
"The plan to have Turbofan 20 participate in next year's Singapore Air Show remains unchanged, but I have recently found an opportunity to disclose relevant information in advance... Although the British are anxious now, it may not be embarrassing if they contact us directly to request cooperation. Secondly, we can’t explain the source of the intelligence, so we have to find a way out for them.”
He had already figured out the nature of these old Europeans.
A bit like a kitten.
She has to smooth her hair down, and she is quite arrogant.
But as long as you master the skills, it's actually quite easy to deal with.
Ren Bingda rolled his eyes and quickly thought of a countermeasure:
"That's just right. There will be an Asian Civil Aviation Trends Forum the day after tomorrow. It will be held in Singapore. It's purely a retreat."
"Aviation Technology Group is preparing to sign a long-term contract with the organizer of the Singapore Airshow at this forum to ensure the scale of participation in the next five airshows in the next ten years in exchange for a discount on the booth price... You can take this opportunity to mention a little bit about this The highlight of this exhibition, Luo Luo was interested in it anyway, we just need to make a gesture and it should be fine..."
"It works."
Chang Haonan nodded immediately:
"You should be responsible for this matter. Just wait until the British react and then report it."
"I have a lot to do, I want to focus on the project..."
……
Chang Haonan originally thought that even if he gave him a step, the British would inevitably show their old European spirit and would not react for ten days and a half.
As a result, only three days after the news was released, Ren Bingda approached Chang Haonan again.
"Academician Chang, your analysis is correct, Luo Luo really can't sit still!"
Ren Bingda was in a hurry as before, but this time the expression on his face was filled with uncontrollable joy:
"Mr. Tim Purdy has already sent us a message through Ciro, saying that the cooperation between MTU and Pratt & Whitney has broken the current industry balance. Without the first-mover initiative, it will be difficult for one company to fight against it. The alliance they formed asked us if we are interested in cooperating to develop the next generation of aviation power..."
"So direct?"
Even Chang Haonan felt a little surprised.
"The dialogue itself is very long and full of long and difficult British sentences, but the meaning is basically this..."
Ren Bingda curled his lips, obviously helpless to the British attitude:
"And this itself was an oral communication without written information. The other party also said that if we have the intention to cooperate, we can agree on a time for more formal and in-depth cooperation negotiations."
Chang Haonan tapped the table twice with his fingers:
"Negotiations are of course necessary, but in this cooperation, my goal is to put myself first, so before giving a response, we need to be internally prepared for the difficulties we may face during the negotiation process."
< br>
After finishing speaking, he looked at the other party's doubtful eyes and continued to explain:
"Of course, the British will definitely not make concessions on the surface, so what I mean is that in terms of technology, our country is responsible for the overall coordination and design. Rolls-Royce can provide some key technologies, but they cannot be allowed to turn against customers."
To do this is still very difficult.
But at least there is room for maneuver.
Ren Bingda nodded solemnly and wrote down Chang Haonan's request in his notebook.
Then he raised his head and continued:
"In addition, Academician Chang... In addition to matters related to cooperation, the British still seem to have some concerns about our technology."
Chang Haonan missed the point for a moment and just nodded naturally:
"It's normal to have concerns. After they see the real turbofan 20, they won't worry anymore..."
But Ren Bingda shook his head:
"That's not what I meant... The two British people from Xiro Company went in a big circle with us in the second half of the conversation. On the surface, they kept talking about irrelevant things. In the end, Comrade Zhenhua heard something. Beyond words.”
"It's not that Rolls-Royce doesn't believe it, but it's that it cannot accept it in principle...or it can't understand the role of intercoolers in aircraft engines. It has been trying to trick us, but in the end some information was tricked out."
"The other party seems to think that the temperature difference between the gases involved in heat exchange in the intercooler is small, and the effect on the entire engine will not be obvious. If you want to increase the heat exchange temperature difference between the intercooler, you need to increase the increase in the boost stage and the high-pressure compressor. The proportion of pressure ratio, but this is not worth the gain in principle, but will lead to a decrease in engine performance, so it is strange how we and the Germans overcame this problem..."
After listening, the expression on Chang Haonan's face turned to confusion:
"How could they...ask such a question?"
