Chapter 1681 The war will not end when you want it to end

"Understood, sir." Donilon understood almost instantly. "I will immediately convey your request to the head of the investigation team to ensure that the investigation is carried out with minimal disruption."

This means giving yourself a way out as much as possible when the investigation cannot be withdrawn.

As for the negative impact that has already occurred...

It's so funny, no one really thinks that the two sides are "allies"?

"besides……"

Ao Guanhai was about to speak again when the intercom on the table beeped again.

This time, it was Chief of Staff Pete Rouse standing outside.

Donilon pretended to take a half step back, asking himself with his gesture whether he needed to avoid it.

Then got a negative answer.

The door opened and White House Chief of Staff Pete Rouse hurried in, also holding a document in his hand.

But it was packed in a paper bag and was much thinner.

Seeing that Donilon was still in the office, Ross was obviously stunned for a moment, but then returned to normal.

"Pete, what's the hurry?" Ao Guanhai asked.

As he spoke, his eyes had already fallen on the file bag.

Rouse walked quickly to the desk and put down what he was holding. "This letter just arrived through special channels. It's from California Senator Dianne Feinstant. She emphasized that you need to review it personally and immediately."

Ao Guanhai frowned slightly.

Feinstant is a senior senator who, thanks to the unique distribution of her constituency, is quite influential in Congress, especially on science and technology affairs.

He picked up the document bag and opened the wax seal.

There was only a piece of fine letter paper inside

However, the address and content at the beginning of the letter made him frown even more.

This is not an official letter from Senator Feinstant herself, but rather a suggestion she relayed on her behalf.

Or you could say it's an "ultimatum."

From Elon Musk.

In the letter, the other party expressed extreme concern about the current global economic situation in rare and almost straightforward terms.

He pointed out that the nature and depth of the financial tsunami triggered by Black Monday were completely different from any economic crisis in the past four decades, and Wall Street's control over the global financial system had exposed unprecedented fragility in this crisis.

Even the most elite capital, with its ability to hedge and transfer risks, pales in the face of the risk of systemic collapse. We are all tied to the same sinking ship; no one can truly remain above the crisis.

The letter then directly criticized the current policy:

"At this critical juncture for the global economy, escalating tensions across the Pacific is not only unwise but also completely unacceptable and strategically shortsighted..."

Musk also mentioned his last trip to China, with obvious regret and dissatisfaction in his tone.

"I had the opportunity to build a bridge of mutual trust between SpaceX and China through in-depth cooperation in the aerospace field. However, after my return, SpaceX's business activities, especially those involving international cooperation, were subject to numerous additional restrictions and scrutiny from Washington. This missed the opportunity and forcibly closed the window for cooperation, indirectly leading to the current complete breakdown of trust and the outbreak of this financial disaster."

Then, the other party put forward his solution, or the terms of the deal:

"However, there is still room for improvement. China's enthusiasm and commitment to the Beacon program are unquestionable, and the Falcon Heavy is the only operational vehicle in the world that has been proven capable of sending a heavy module directly into Earth-Moon transfer orbit."

"As long as Washington can substantially relax restrictions on SpaceX's technological investment and commercial cooperation in China, and allow us to participate in launch services and even modular cooperation related to the construction of the 'Beacon' space station, I believe this can become a key entry point for restarting dialogue and stabilizing the situation..."

"..."

At the end of the letter, Musk's words became tougher and even threatening:

"Global economic stability is in the fundamental interests of everyone, including SpaceX shareholders and employees. However, if the current confrontational dynamics cannot be effectively eased, and if Washington continues to ignore the possibility of resolving the crisis through pragmatic cooperation, then I will be forced to reassess my current support and may even turn to supporting forces that are more willing to adopt rational and pragmatic strategies for the sake of the company and the broader economy..."

Traditionally, the high-tech industry has been a loyal supporter of the Donkey Party.

But this stock market crash was so severe that no one can guarantee what the next situation will be like.

After reading the letter, Ao Guanhai's brows were tightly locked together, and a trace of offended anger flashed across his face.

But the anger didn't last long.

His eyes lingered repeatedly on the few lines at the end of the letter about the complementarity between the "Falcon Heavy" and the "Beacon", and when he thought of the dilemma he had just discussed with Donilon, a vague idea gradually became clear in his mind.

"Heh..." Ao Guanhai chuckled with an ambiguous meaning, which attracted puzzled looks from Ross and Donilon.

"Pete, Tom." Ao Guanhai raised the letter in his hand, a glimmer of light rekindled in his eyes, "I think... we have found a way to end this in a decent way."

……

Two days later, China, Beijing, China Aerospace Science and Technology Corporation Sixth Academy.

In a conference room full of people.

The projection screen in the front was filled with dizzyingly complex mathematical symbols, topological diagrams, and fluid mechanics equations.

Chang Haonan was standing behind the podium, patiently explaining how to transform the general solution of the NS equations - the highly abstract topological framework that describes the ultimate form of fluid motion equivalence class - into a specific model that can be used in engineering practice.

"...The key lies in understanding the topological invariance and bifurcation points of the generation, evolution, and annihilation of turbulent vortices." Chang Haonan circled several key topological structure diagrams on the screen with a laser pointer. "By introducing the dimensionality reduction mapping of 'strange attractors', we can transform the complex flow field evolution in high-dimensional phase space into a set of relatively low-dimensional characteristic matrices with clear physical meaning. These matrices are the direct input for engineering optimization."

He switched to a PPT, which showed a simplified design diagram of the YF-177 rocket engine combustion chamber and a graph of measured data of high-frequency pressure oscillations, the amplitude of which was shocking.

"Take the long-standing low-frequency combustion oscillation problem of the YF-177 as an example," Chang Haonan said, his gaze sweeping over Chief Engineer Li Renping and others seated in the front row. "Traditional empirical methods like modifying the injector configuration and adding acoustic cavities have limited effectiveness and unclear mechanisms. Now, based on the turbulent energy level string model derived from the general solution and the pressure pulsation source term identification algorithm, we can directly optimize it on paper."

He pretended to pick up an electronic pen.

Of course, even the simplest partial differential equations cannot be calculated by hand.

So it was just a page turn.

The following are the calculation steps that have been prepared long ago——

Simplifying one by one, substituting into the characteristic matrix, solving the eigenvalues... The whole process went smoothly and the audience was silent.

The audience stared with their eyes wide open, closely watching every step Chang Haonan took, with shock on their faces.

After about twenty minutes, the entire calculation process was demonstrated.

The final conclusion section lists the comparative data of key oscillation modes based on model prediction before and after optimization.

"According to model calculations," Chang Haonan pointed to the significantly reduced oscillation amplitude curve in the predicted results, "using this optimization solution, the YF-177's main combustion chamber pressure oscillation intensity under rated conditions is expected to be reduced to less than 15% of the original design. This will significantly improve the stability margin."

He paused and added, "Of course, according to current design specifications, this still requires subsequent ground hot tests for final verification, but the theoretical bottleneck has been broken..."

The conference room was instantly filled with suppressed exclamations and whispers.

Relying solely on paper calculations, a clear and quantitative solution was provided to an engineering problem that had plagued them for years in such a short period of time, which completely subverted the traditional engineering R&D model.

Li Renping rubbed his hands excitedly and looked at Chang Haonan with eyes full of admiration, as if he had seen a new era in the field of aerospace propulsion.

At this moment, the door of the conference room was gently pushed open a crack.

A secretary leaned forward and gestured to Lan Xinzhi who was traveling with Chang Haonan.

The latter frowned slightly, gave Chang Haonan an apologetic look, then stood up and walked out of the meeting room.

Chang Haonan certainly noticed this little episode, but he did not pause and continued to answer several questions raised by the experts in the audience about the boundary conditions of matrix solutions.

A few minutes later, Lan Xinzhi pushed the door open again, with a hint of...subtlety on his face.

He returned to his seat, but did not sit down immediately. Instead, he leaned slightly closer to Chang Haonan and whispered a few words in a voice that only the two of them could hear.

After listening to this, Chang Haonan still maintained the same expression on his face and just nodded slightly.

Then he raised his hand and signaled: "Let's adjourn for fifteen minutes. Everyone, take a break and drink some water."

After the sound of relaxed conversation and the shuffling of chairs could be heard in the conference room, Chang Haonan turned to Lan Xinzhi:

"A call from the Commission? Washington?"

"Yes." Lan Xinzhi nodded, speaking a little quickly. "In the emergency report we just received, the other party expressed a strong desire to have a 'high-level, constructive' dialogue as soon as possible. The level...meaning the highest level."

"What are the conditions?" Chang Haonan didn't say any nonsense.

Lan Xinzhi replied, "They hope to simultaneously lift all restrictions implemented since December 2014, 12, and are willing to support SpaceX's investment plans to establish a wholly-owned subsidiary in China, build a rocket and spacecraft manufacturing plant, and construct a dedicated launch site in a qualified location in the future. They imply that this could serve the construction of the 'Beacon' space station."

"Tsk...what were you doing so early?"

Chang Haonan sneered, then slowly turned around and looked at the huge projection screen behind him.

The above is the derivation process and final result of the YF-177 engine combustion oscillation optimization that has just been completed.

When your car hits a tree, you know to turn; when the stock price goes up, you know to buy; when you make a mistake and are sentenced, you know to repent.

It's too late!

"Now if we want to end this gracefully...I'm afraid it's not that easy."
