Chapter 1638: The West is Dark, the East is Bright
From the outside, it seemed that Chang Haonan's pupils shrank slightly at this moment, and he turned a deaf ear to the deafening cheers around him.
The whole person seemed to be under a spell, standing still without moving.
After a long while, a hand gently patted his shoulder, forcibly pulling him back to reality from the flow state that was almost like "enlightenment".
It’s Xing Muchun.
"Mr. Chang?" The other party obviously noticed Chang Haonan's strange silence just now, as well as his slightly pale face at the moment, "You don't look well."
He seemed frightened by the situation:
"Do you want to ask a doctor to come over, or... sit in the lounge for a while?"
Chang Haonan suddenly came back to his senses, blinked subconsciously, then took a deep breath, and forced himself to suppress the torrent of thoughts that were still churning in his mind.
He shook his head slightly and then checked the time.
It's strange, I just thought about so many things, but in fact only less than a minute passed.
"It's okay, Lao Xing."
As soon as he opened his mouth, he realized that his voice was a little hoarse, so he cleared his throat:
"I don't feel uncomfortable anywhere." He paused, looked at the crowd still celebrating excitedly, and found a suitable excuse, "Just now... I just watched it fly up, and I felt a little emotional."
Upon hearing this, Xing Muchun's face also showed a sigh of sympathy, and he sighed heavily:
"Yeah, I can't believe it. It's only been less than ten years... We have gone from never even reaching the threshold of hypersonics to... where we are today!"
His tone was also full of pride.
However, most of Chang Haonan's mind at this moment was still occupied by the inspiration about the NS equation that had just flashed through his mind.
Like a hot brand, it burned his mind.
But the cheers around him and Xing Muchun's emotional memories made it impossible for him to immerse himself in it.
Chang Haonan tried hard to mobilize his facial muscles, trying to show the joy he should have, but the curve of his mouth seemed a little stiff.
He had no choice but to turn his gaze back to the big screen, pointing at the speed curve that was still slowly but steadily rising, and changed the subject:
"Now, it depends on how fast it can fly in the end."
Xing Muchun keenly captured the unusual emotional fluctuations that Chang Haonan tried hard to conceal.
He took a half step closer, lowered his voice, and asked with tentative concern: "Boss Chang, why do I feel... that you don't seem particularly happy? What... are you still not satisfied with?"
He thought Chang Haonan had some reservations about the current speed or performance.
Chang Haonan tried to move the corners of his mouth again, but finally gave up forcing a smile and shook his head slowly and very slightly.
His eyes were still fixed on the screen, as if he wanted to penetrate the plasma densely surrounding the fuselage and see through the essence of the fluid.
"It has nothing to do with this." He explained, "Just now, when it broke through Mach 5, I seemed to... seemed to have caught something."
"Caught something?"
Xing Muchun was stunned and didn't understand what was going on.
"Yes." Chang Haonan nodded affirmatively, and finally turned his head to look at Xing Muchun, "A key... that may lead to solving the ultimate problem of fluid mechanics."
Xing Muchun's movements suddenly stopped.
As a top aerospace propulsion expert, he instantly understood what Chang Haonan meant.
Then he felt a little bit unbelievable.
Academician Chang's ability is indeed beyond imagination, but that goal...
He confirmed in a trembling voice: "The ultimate question, is it... the NS equation?"
Chang Haonan didn't say anything.
Just nodded again, slowly but solemnly.
Just as the two were whispering about their epiphany that would shock the entire scientific community, the speed curve of the "Zou Yu" had begun to flatten out visibly.
Finally, when approaching the astonishing speed of around Mach 9.2, the curve is completely flattened and the acceleration returns to zero.
It reaches the speed balance point for waverider flight at the current altitude, air density and engine thrust.
This number also perfectly matches the design goals originally set for the project!
Seeing the speed curve stabilize, Chang Haonan temporarily suppressed the thoughts in his mind and once again showed the decisiveness that a project chief engineer should have.
He raised his voice:
"Target speed achieved! The objectives of this flight test have been successfully completed! Prepare for the return procedure!"
Then, he turned to Bian Lizhen, who had been paying close attention to the testing process:
"Boss Bian, after the plane lands and the data is recovered, compile a high-definition version of the footage captured by the front and rear cameras, especially the takeoff and the Mach 5 breakthrough."
“This time, we will take the initiative to promote it!”
……
One day later, December 2014, 12.
The Chinese government simultaneously released a brief but earth-shattering piece of news through multiple authoritative news platforms:
[Yesterday (December 12), my country successfully conducted the first flight test of a new type of air-breathing hypersonic aircraft. The test verification aircraft, code-named "Zuo Yu", uses a combination of jet engines and ramjet engines. For the first time, it achieved a full process of controllable flight from ground autonomous takeoff, autonomous mode conversion, hypersonic cruise to autonomous return and landing. It has made major breakthroughs in multiple core technologies, indicating that my country has reached the world's leading level in this field. ]
Released along with the news was a carefully edited high-definition video of about one minute in length.
The video begins with the runway of Zhongbeiling Airport in winter.
A black aircraft with a futuristic appearance, with dazzling afterburner flames spewing from its tail, flew from slow to fast, and finally left the ground with its head held high.
Then, the screen switches.
It's still that aircraft.
But this time, it was high in the sky.
The moment the two ramjets at the rear burst into dazzling light like the sun, the speed value clearly marked in the upper right corner of the screen broke through a suffocating threshold -
Mach 5.0.
The shorter the words, the bigger the news!
Once this news was released, it shocked the world!
For insiders, air-breathing hypersonic aircraft are nothing new.
But compared with the previous "Cold", X45, and X51A, what the Chinese announced this time is obviously an "aircraft" in a more traditional sense.
In other words, it’s definitely reusable!
After a brief silence, the international mainstream media immediately reported the event at the fastest speed, with headlines filled with words such as "breakthrough", "milestone", and "game-changing".
Experts and analysts in the fields of aviation, aerospace, and military were pushed onto the screen, trying to interpret the terrifying technological strength behind this news and its far-reaching impact on the future.
Almost all eyes were subconsciously and nervously cast towards the other side of the Pacific Ocean.
The Chinese have broken through the limits set for humans by air and fluids.
How will Washington react?
For a moment, the world seemed to have returned to the era 40 years ago, when the "space race" was carried out at all costs on both sides of the Iron Curtain.
十个小时后，美国东部时间2014年12月31日上午（华夏时间12月31日深夜），来自华盛顿的官方声明终于发布。
However, its content forms a sharp and ironic contrast with the world's expectations:
[The Bureau of Industry and Security (BIS) of the Department of Commerce officially announced today that the following entities will be included in the 'Entity List', which will take effect immediately...]
The statement did not stop there, but went on to list a series of shocking names:
[Juchang Technology Co., Ltd., Huaxing Technology Co., Ltd., Huaxin International Integrated Circuit Manufacturing Co., Ltd., Shanghai Shanghai Microelectronics Equipment Co., Ltd., Changguang Group Precision Optics Co., Ltd., Gaojing Electronic Technology Group...]
The list is still expanding, covering dozens of China's top technology companies and research institutions, from chip design software, semiconductor manufacturing equipment, key material suppliers to precision optical device research and development.
The statement accused these entities of "engaging in activities contrary to the national security and foreign policy interests of the United States" and claimed that the move was intended to "prevent advanced U.S. technology from being used to support destabilizing military modernization programs."
The announcement details the categories of items that are prohibited from export, re-export or transfer, covering almost all key U.S. technologies and equipment that may be used in advanced semiconductor manufacturing, design and communications equipment production.
The scope of the sanctions far exceeds the most pessimistic predictions of the outside world.
This heavy blow, with its unquestionable hegemonic will, hit the fragile foundation of global scientific and technological cooperation hard.
the same day.
One party announced a hypersonic aircraft that will open a new chapter in human aviation history.
The other side launched the most severe ban in history on the core technology industry.
Two completely opposite but equally shocking pieces of news were like two bolts of lightning tearing through the sky.
The last day of 2014 will forever be frozen in the most ironic and solemn page in the history of human technology.
