Genius is just the threshold for me!

The next day, Friday, after school in the afternoon, Xu Qingling was called over by her homeroom teacher to be given some instructions.

When she returned, apart from Lin Dong and his group waiting for her, almost all the other classmates had left.

Just then, Xia Ran saw Xu Qingling return and, as if remembering something, asked in a low voice, "Qingling, is Uncle Xu coming back from his business trip today?"

"yes."

Xu Qingling nodded: "They said they'd be going back today. I remember Uncle Xia went on the business trip with them too."

"Um."

Xia Ran smiled and said, "My mom asked me yesterday when I would be back, and said it's still uncertain."

"Then we should have arrived by now."

Xu Qingling responded with a smile, took the schoolbag from Lin Dong, and the group started walking back.

"Qingling".

At this point, Huang Qingyao asked with some distress, "Your homeroom teacher also told you about preventing drowning during summer vacation and not swimming in unsupervised areas, right?"

"Uh-huh."

Xu Qingling nodded: "There's only one week left until summer vacation. She asked me to discuss with our class's life publicity committee member to make some graphic materials, which will be printed out and distributed next week."

"Illustrated materials? Just print them out and distribute them?"

Huang Qingyao stared wide-eyed in disbelief: "Why do I have to prepare a themed PowerPoint presentation and a themed class meeting, and give a presentation during the last period before the holiday next week?"

"Is that even a question?"

Su Yue chimed in from the side, "Yaoyao, your aunt values ​​you and is grooming you."

"Oh my god, they should really give this kind of attention to someone else."

Huang Qingyao couldn't hold back any longer: "How many years is she trying to train corporate slaves in advance?"

"Go for it!" Su Yue gave a thumbs-up.

"Go for it!" Xu Qingling, Xia Ran, and Jiang Caiping, the three girls, gave each other a thumbs-up.

"Go for it!" Lin Dong, Li Tao, and Zhang Yihao chimed in, not wanting to be left behind, and gathered around him.

"Get lost, you bunch of frenemy friends..."

Upon seeing this, Huang Qingyao quickly waved her hand as if exorcising evil spirits, driving everyone away.

The group played and joked all the way back to their residential compound. Lin Dong asked Xu Qingling to help him take his schoolbag back, and then strolled over to Laboratory No. 78 by himself.

After entering his password and fingerprint, Lin Dong didn't linger. He pushed open a hidden door leading to the next room and entered Xu Ziming's assembly workshop.

Lin Dong walked about ten meters down the corridor, entered the password, pushed open another door, and came to a workshop next door. Xu Ziming and Jiao You came into view.

In front of the two men was a large engine, more than 5 meters long and 1 meter in diameter, fixed on a heavy-duty test stand. It was connected to oil pipes and various cooling pipes.

This used to be a regular processing workshop with low utilization.

Lin Dong's original subsonic Hot Spicy No. 1 had its entire fuselage and most of its engine parts processed here by Zhang Yue, that beast of burden.

However, just as Xu Ziming's small final assembly workshop was being renovated and built, the Emei project also came to Chengdu Aircraft Industry Group.

Here, to meet the testing needs of the Emei project, the equipment was cleared out, and a series of load-bearing foundations, heavy beams, and other foundation concrete were added. Various equipment was then added and the site was transformed into a heavy-duty test bench.

This not only facilitates engine testing for the Emei project team, but also makes it easier for Lin Dong to test any large engines he develops in the future.

Otherwise, a high-thrust engine can easily generate tens or even twenty tons of thrust. Add to that the terrifying intake, exhaust, and waste heat during testing, and it's simply not something that can be met in an ordinary environment.

"Uncle Xu, Uncle Jiao, how is it?"

Lin Dong felt the lingering warmth in the air as he walked over to a laptop connected to the engine and began examining the various data displayed on it.

"Jiao and his team worked through the night to repeatedly confirm the plan and the entire design calculation process, and the data was all correct."

I also reviewed the entire assembly process and found no abnormalities. There's a general idea, but no one is certain.

Xu Ziming took a deep breath and said in a deep voice, "If this is really the problem, the situation will be very troublesome."

"Is it a manufacturing defect, or is the quality of the entire batch of parts poor?"

Lin Dong frowned, immediately realizing what problem Xu Ziming was referring to.

Even though its small engine, Hot No. 2, uses a cyclic design, the total number of parts is less than two thousand.

The Emei WS-15 turbofan engine, a high-thrust engine, has nearly three thousand core components alone.

If you include the external pipes, cables, valves, sensors, and various connectors, the total number of parts jumps to over 40,000.

These many parts need to be tightly integrated to form an engine that can generate more than 18 tons of thrust.

Even minor issues in the manufacturing process or substandard parts batches can accumulate and directly become major problems affecting the normal operation of the entire engine.

But if that's the problem, then things are really bad.

This means that the design plan for the Emei project has encountered the most serious and disastrous situation: it is over-engineered.

The entire design surpasses current industrial standards and exceeds the limits of parts that the national industrial system can manufacture.

This means that the entire Emei project will be suspended in mid-air; even if the design is completed, it cannot be actually manufactured and implemented.

"Yes, that's the only question we can think of right now."

Jiao You looked at the first WS-15 turbofan engine they had researched for nearly ten years, from the initial plan to the blueprints, and from the blueprints to reality, and his eyes turned a little red.

"We've ruled out all other possible problems, and we've recalculated all the data, but it just won't work..."

Jiao You's voice was filled with helplessness and despair. Towards the end, his voice choked with emotion, and he could no longer continue. He could only look at the high-thrust engine in the distance, which had taken ten years and countless resources to develop, but was still destined to fail.

"Uncle Jiao, don't worry, problems with the manufacturing process and parts aren't so easy to determine... Uncle Xu, let's test the car again and check the real-time data during operation."

Lin Dong comforted Jiao You, then quickly flipped through the currently collected data with the mouse, and turned to Xu Ziming, saying, "This data collected afterward doesn't reveal much."

"The test drive data has been saved and hasn't been cleared yet. Please take a look."

Xu Ziming pointed to the computer in the control room behind him, but did not refuse Lin Dong's request to test drive the car again.

He unplugged the laptop cable, gestured for Lin Dong and Jiao You to move aside, and pressed two buttons on the side, causing the heavy-duty explosion-proof doors on both sides to slowly close.

The three then moved to a control room in a distant corner, where they monitored the situation in the test workshop through special cameras and microphones, separated by several walls.

woo-

Upon arriving at the control room, Xu Ziming pressed the test start button, and the entire workshop immediately roared to life.

The front and rear baffles of the WS-15 engine opened, and the high-power, high-flow axial fan inside the duct slowly started.

Once the fan reached a certain speed, Xu Ziming pressed another button, and through the camera, the blades of the WS-15 began to rotate, driven by the motor.

buzzing-

The entire test workshop roared with a deafening roar. Once the engine reached a certain speed, it vibrated violently and emitted a plume of black smoke from the nozzle.

Rumble!

The engine revved rapidly, and blue flames with a hint of yellow shot out from the exhaust pipe.

The powerful thrust was transmitted through the test stand to the load-bearing base, and the entire floor could be felt to vibrate slightly.

The high-powered axial fan in the air duct was also accelerating at the same time, continuously supplying a large amount of fresh air to the front of the engine.

The fan in the exhaust pipe behind the engine is also working simultaneously to draw away the exhaust gases emitted from the engine.

Lin Dong glanced at the engine running continuously on the test stand, then looked at the screen in the control room, watching the data that kept jumping and refreshing.

"30% thrust... 40% thrust... 45% thrust... 48% thrust... Boom! Boom boom boom!"

When the operation is increased to 48% thrust.

Suddenly, the previously smooth engine sound abruptly stopped, as if it had caught its breath, and the entire data interface went haywire.

"This data..."

Lin Dong's gaze sharpened as he stared at the key but now scrambled data that kept refreshing on the screen. After carefully examining it for more than ten seconds, he decisively closed his eyes and recalled the entire design of the WS-15 engine, then plugged these data back into the system.

call--

A simulated turbofan engine popped into my mind.

Every turn, every jolt, every thrust fluctuation of the engine, the operation of every core component, and even the flow of every stream of air were all clearly reflected in Lin Dong's mind.

"Xiao Dong!"

At this moment, Xu Ziming noticed Lin Dong's actions and initially thought he was just thinking.

But less than half a minute later, Lin Dong's face suddenly turned pale, and beads of sweat appeared on his forehead under the air conditioner. He immediately called out.

"call!"

Just then, Lin Dong opened his eyes, took a few deep breaths to restore his color, and turned to look at the WS-15 engine on the monitor screen, which was constantly spewing out plumes of black smoke and yellow flames from its tailpipe and roaring incessantly.

"The problem is that the quality of a particular batch of parts is poor, and the solution has reached an industrial bottleneck, but the difference isn't that significant..."

Lin Dong shook his head and said in a deep voice, "Uncle Xu, Uncle Jiao, prepare for large-scale production. We'll push forward with industrial-scale production first, select the corresponding parts, and get the engine out..."
