The military-industrial scientific research system of the academic master

Due to time differences and distance, China often receives news from Europe and the United States a little later than the United Kingdom.

In the evening of the same day in Beijing time, Chang Haonan was looking at the computer, checking the decision plan on the power system of the hypersonic verification missile that had just been sent from the Sixth Academy of Aerospace.

After all, the test equipment was developed based on mature technology as much as possible, and it was not intended to be finalized from the beginning, so whether it is the warhead, guidance system, control system or power system, the test process is to be quick and simple under the premise of ensuring basic reliability.

Including the name YF76, it was actually given by the Sixth Academy itself.

After more than half a year of high-frequency testing, this cryogenic liquid rocket engine has now reached the conditions for loading.

As long as a few more joint exercises with the rocket body are carried out to confirm that the balance of the missile itself is not a problem, the production process of the verification missile can be officially started.

If Gaofei Group's transformation of Tu-160 is fast enough, it may be able to complete the first test before the beginning of next spring.

Of course, according to the plan, it is also the only test.

After the JF14 wind tunnel is built, the main attention will be devoted to the two real black technologies, waverider and scramjet.

As for the results of this verification bomb, it will probably be used to develop a solid-fuel double-cone superbike with practical value.

Thinking of this, Chang Haonan couldn't help but smile.

The idea of ​​"magnetic fluid power generation" in his mind became more and more eager.

It has been nearly ten years since he was reborn.

However, due to the speed limitations of 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, using the experience of the previous life, many key nodes were advanced for a period of time.

And now, there is finally some spare time and resources to do some real black technology that he had 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.

In order to facilitate the entry and exit of technicians, his office is rarely closed.

So as soon as he looked up, he could see Ren Bingda standing outside the door.

Chang Haonan immediately motioned for him to come in.

Ren Bingda walked quickly, opened the folder under his armpit, turned it 180 degrees, and put it on the desk:

"Mr. Chang, the latest situation just confirmed is that MTU announced that it will cooperate with Pratt \u0026 Whitney to develop a new generation of civil aviation power, which is planned to be used for a new generation of large regional and single-aisle medium-sized trunk aircraft. The level should overlap with our AE1500."

Chang Haonan's right hand, which was flexibly sliding the mouse, suddenly paused.

The smile on his face also disappeared.

He quickly picked up the folder and quickly scanned the contents on it.

"PW1200 and PW1500..."

"The entire project is expected to be completed in four stages..."

"Gear drive, counter-rotating turbofan..."

When he saw the last part, Chang Haonan couldn't hold it back at all:

"Why do you also want to develop intercooled and reheated turbofan engines... or with Pratt \u0026 Whitney?"

MTU and Pratt \u0026 Whitney have always cooperated, and he knew about this.

Including the PW1000G engine designed for the Airbus A318 passenger aircraft, which also uses a lot of MTU's unique technology.

But using technology from each other is one thing, and directly announcing that they are in the same camp is another.

Even for him, this is completely different from the initial expectations.

Fortunately, it is a deviation in a favorable direction.

So this news only brings surprise, not shock -

In fact, the reason why the AE1500 project has been rushing to make progress before, and even "leaking" to the British side, is largely to prevent MTU from hooking up with Rolls-Royce before itself.

After all, in the original timeline, it was the latter that acquired MTU's parent company.

But now it seems that it seems to have made a mistake in thinking.

Before the global financial crisis in 2008, the Germans were not necessarily willing to get too close to the British.

As for Pratt \u0026 Whitney...

Although it is nominally a Canadian company, the North American environment can only be said to be understood by those who understand it. Canada's independence is not as good as Japan and South Korea to some extent.

Therefore, from the beginning, Chang Haonan did not include him in the list of candidates for pursuit.

In the previous life, China had to deal with Pratt \u0026 Whitney for many years because it had to import many turboshaft/turboprop engines from the other party.

Now, there is no such concern.

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 Company back then had no psychological burden when selling out their teammates... In this situation, Rolls-Royce must feel a full sense of crisis."

Chang Haonan sighed half with emotion and half with 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 in their hearts for a few months, and then at the Singapore Air Show next year, we will confirm the news that we have the indirect cooling and heating technology. This step-by-step approach will make it easier for the British to accept it."

"Who would have thought that the Germans would help us a lot and save all these steps in the middle..."

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 \u0026 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 plans must be adjusted accordingly?"

Ren Bingda asked cautiously.

"Um……"

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 for them to get off.”

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 is purely for 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 this a little bit. The highlight of this exhibition, Luo Luo was interested in it anyway, we just need to make a gesture and it should be fine..."

"feasible."

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 \u0026 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 were 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 with no written information retained. 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."

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 I am talking about the technical aspect. 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 again and continued:

"In addition, Academician Chang... apart from 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 matter-of-factly:

"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 the intercooler in aeroengines. 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 pressure between the supercharging 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 hearing this, the expression on Chang Haonan's face turned to confusion:

"How could they...ask such a question?"
