Chapter 1225 British People's Doubts

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

In the evening of that day, Beijing time, Chang Haonan was sitting in front of the computer, checking the decision plan on the hypersonic verification missile propulsion system that had just been sent from the Sixth Academy of Aerospace Science and Technology.

After all, the test equipment was developed by relying on mature technology as much as possible, and it was not intended to be finalized from the beginning. Therefore, whether it is the warhead, guidance system, control system or power system, the test process is to be fast and simple while 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 condition where it can be loaded with ammunition.

As long as we conduct a few more joint exercises with the rocket body 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 Gaofei Group can modify Tu-160 quickly enough, it may be able to complete the first test before the beginning of next spring.

Of course, according to the plan, this was also the only test.

After the JF14 wind tunnel is completed, the main attention will be focused on the two truly black technologies: waverider and scramjet engine.

The results of this demonstration missile will probably be used to develop a solid-fuel, double-cone high-altitude missile with actual combat value.

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

The idea of ​​"magnetic fluid power generation" became more and more active in my mind.

It has been nearly ten years since he was reborn.

However, due to 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, by utilizing the experience of previous lives, many key nodes were moved forward for a period of time.

And now, he finally had some spare time and resources to develop some real black technology that he had never seen in his previous life...

Just as Chang Haonan was immersed in the beautiful vision he had outlined, a hurried knock on the door outside interrupted his thoughts.

To facilitate the entry and exit of technical personnel, his office is rarely closed.

So when I looked up, I could see Ren Bingda standing outside the door.

Chang Haonan immediately motioned for the other party to come in.

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

"Mr. Chang, the latest news just confirmed is that MTU has announced a partnership 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 trunk aircraft. The level should overlap with our AE1500."

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-driven, counter-rotating turbofan..."

When he saw the end, Chang Haonan couldn't hold it in any longer:

"Why are you also going to develop a reheated turbofan engine... together with Pratt & Whitney?"

He knew that MTU and Pratt & Whitney had always been cooperating.

Including the PW318G engine designed for the Airbus A1000 passenger aircraft, it also uses many of MTU's unique technologies.

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

Even for him, this was completely different from what he had initially expected.

Fortunately, it deviated in a favorable direction.

So this news only brought surprise, not shock—

In fact, the reason why the AE1500 project had been rushing to meet deadlines, even at the cost of leaking information to the British, was 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.

But now it seems that we have made a mistake in our mindset.

Before the global financial crisis in 08, the Germans were not necessarily willing to get too close to the British.

As for Pratt & Whitney...

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

Therefore, from the very beginning, Chang Haonan had not included her in his list of candidates for pursuit.

In the previous life, China was forced to deal with Pratt & Whitney for many years because it had to import a lot of turboshaft/turboprop engines from the other side.

There is no such concern now.

His goal has always been to tie down Europe and deal with North America.

"I never expected that the companies that formed International Aero Engines would sell out their teammates without any psychological burden... Under the current circumstances, Rolls-Royce must feel a strong sense of crisis."

Chang Haonan sighed half with emotion and half with sarcasm:

"My original plan was to take advantage of the Rolls-Royce delegation's visit to China last month to reveal some key information, and then let them buffer it in their minds for a few months. At next year's Singapore Air Show, we will confirm the news that we have indirect cooling and reheating 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 so much and save us all these steps..."

In fact, what Chang Haonan didn’t know was that the German had inadvertently given more than just assists.

If there had not been a sudden official announcement from MTU and Pratt & Whitney, Rolls-Royce might have been misled by internal personnel and refused to believe in the possibility of applying indirect cooling and heat recovery technology to the field of aviation engines.

Although you will definitely be slapped in the face in the end, it is inevitable to waste time going back and forth.

"So we need to adjust our plans accordingly?"

Ren Bingda asked cautiously.

"Um……"

Chang Haonan pondered for a moment:

"The plan to have the WS-20 participate in the Singapore Air Show next year remains unchanged, but we will find an opportunity to disclose relevant information in advance... Although the British are anxious now, if they contact us directly to request cooperation, they may not be able to save face, and they will not be able to explain the source of the intelligence. We have to find a way for them to save face."

He had already figured out the temperament of these old Europeans.

A bit like a kitten.

You have to stroke the fur along the way, and it's quite arrogant.

But as long as you master the skills, it's actually quite easy to deal with.

Ren Bingda's eyes turned and he quickly thought of a solution:

"That's perfect. There will be an Asian Civil Aviation Trends Forum the day after tomorrow, held in Singapore. It's purely for academic purposes."

"Aviation Technology Group plans to sign a long-term contract with the organizer of the Singapore Air Show at this forum, guaranteeing the scale of participation in five air shows in the next ten years in exchange for a discount on the booth price... We can take this opportunity to briefly mention the highlights of this exhibition. Rolls-Royce is also interested anyway, so we should just make a gesture..."

"feasible."

Chang Haonan nodded immediately:

"You are responsible for this matter. Just report it after the British react."

"I have a lot of things to do. I need to focus on the project..."

……

Chang Haonan originally thought that even if he gave the British a way out, they would inevitably show the old European spirit and would not react for ten days or half a month.

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 is really getting restless!"

Ren Bingda was in the same hurry as in the previous few days, but this time his face was filled with irrepressible joy:

"Mr. Tim Bodie has sent us a message through Silo, saying that the cooperation between MTU and Pratt & Whitney has broken the current balance of the industry. Without the initiative, it will be difficult for a single company to fight against the alliance they have formed. He asked us if we are interested in cooperating in the development of the next generation of aviation power..."

"So direct?"

Even Chang Haonan felt a little surprised.

"The dialogue itself is quite long and full of long and difficult British sentences, but that's basically what it means..."

Ren Bingda curled his lips, obviously helpless about the British attitude:

"This was a verbal exchange with no paper records. The other party also said that if we were interested in cooperating, we could agree on a time to conduct more formal and in-depth cooperation negotiations."

Chang Haonan tapped the table twice with his fingers:

"Negotiations are of course necessary, but my goal in this cooperation is to be self-centered, so before giving a response, we need to be 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 not make concessions on the surface, so I mean in terms of technology, my country will be responsible for overall coordination and design, and Rolls-Royce can provide some key technologies, but we cannot let them take over."

It is still very difficult to achieve this.

But at least there is room for maneuver.

Ren Bingda nodded seriously and wrote down Chang Haonan's request in his notebook.

Then he raised his head again and continued:

"Also, Academician Chang... apart from the cooperation, the British still seem to have some concerns about our technology."

Chang Haonan didn't quite grasp the point for a moment, and just nodded as a matter of course:

"It's normal to have concerns. Once they see the real WS-20, they won't have any more concerns..."

But Ren Bingda shook his head:

"That's not what I meant... The two British people from Xiluo Company went around in circles in the second half of the conversation. On the surface, they were talking about irrelevant things, but in the end, Comrade Zhenhua heard some hidden meanings."

"It's not that Rolls-Royce doesn't believe us, but they can't accept it in principle... or they can't understand the role of the intercooler in an aircraft engine. They kept trying to trick us, but in the end they got some information out of us."

"The other party seems to think that the temperature difference of the gas involved in the heat exchange of the intercooler is small, and the effect on the entire engine will not be very obvious. If the temperature difference of the heat exchange of the intercooler is to be increased, the ratio of the supercharging stage to the supercharging ratio of the high-pressure compressor must be increased. However, in principle, this is not worth the loss. Instead, it will lead to a decrease in engine performance. So it is strange how we and the Germans overcame this problem..."

After hearing this, Chang Haonan's expression turned into confusion:

"Why would they ask such a question?"
