Her explanation hit the nail on the head, leaving Wang Tiezhu speechless for a moment.
"What about the harm?" Zhang Meng asked in a deep voice, this was the key question.
"In the short term: it accelerates structural fatigue, which may lead to microcracks in the skin or loosening of the connectors, and poses huge long-term risks."
Mingzhao's answer was undisguised: "In extreme cases, if the amplitude increases or the frequency changes, it may trigger more dangerous coupled vibrations, which could lead to structural failure."
This word brought the atmosphere in the entire analysis room to a freezing point.
The joy of the successful maiden flight vanished, replaced by a heavy sense of crisis.
A fighter jet with potential structural resonance issues is no different from a time bomb.
"This must be resolved!" Zhang Meng said decisively. "Comrade Mingzhao, what's the plan?"
Mingzhao stood up and walked to the huge "Shadow" structural blueprint on the wall.
She picked up a red and blue pencil and drew a striking red circle in the area where the rear frame of the engine compartment connects to the root of the main wing.
"This is the critical coupling point. We need to take a two-pronged approach: First, optimize the structural design details, adjust the local stiffness distribution, change its natural frequency, and avoid the main frequency band of the excitation source. Second, add special damping materials at key nodes to absorb vibration energy."
"Special damping materials?"
Su Xuan immediately thought of the arduous research and development process of microwave absorbing materials, "We don't have this kind of reserve right now! The research and development cycle..."
"We have a direction."
Mingzhao's tone carried an undeniable certainty, her gaze seemingly piercing through the walls, piercing into some interstellar knowledge base deep within her memory. "Give me access to the laboratory. I need several basic chemical raw materials and metal powders. Also, retrieve the detailed process records of the last 'Stardust' material synthesis experiment and all remaining byproduct samples."
It's "Stardust" again! Su Xuan and Zhang Meng exchanged a glance, both seeing a glimmer of hope in each other's eyes.
Wang Tiezhu frowned, but this time he did not immediately question it. The data from the maiden flight and Mingzhao's accurate analysis forced him to suppress his doubts.
"Full cooperation!" Zhang Meng immediately ordered. "Su Xuan, you will personally coordinate all the resources Mingzhao needs, giving them the highest priority! Comrade Jiang Feng,"
He turned to the doorway and said, "Raise the lab security level to the highest! All personnel handling experimental data and materials must have their access privileges re-verified!"
"Yes!" Su Xuan and Jiang Feng outside the door responded simultaneously.
Mingzhao said no more, picked up the drawing marked with the abnormal waveform and her notebook, and went straight to the materials laboratory.
Her back remained straight, and her steps were steady and confident.
The heavy laboratory door closed behind her.
Su Xuan immediately began making calls to mobilize supplies.
Wang Tiezhu looked at the closed laboratory door, then at Zhang Meng's solemn profile, and finally just sighed heavily before turning around to organize the relevant data from the wind tunnel test to see if he could find any clues for cross-validation.
In the analysis room, other technicians began to follow Mingzhao's instructions to conduct a more detailed screening of other data from the maiden flight, looking for any clues that might have been overlooked.
The thermal drawing that recorded the subtle vibration waveform was carefully placed separately in a corner of the control panel.
No one noticed that a figure in logistics work clothes briefly lingered in the shadows of the corridor outside the analysis room window.
The person seemed to be just passing by, but their gaze swept quickly across the bustling scene inside, pausing for a moment on the thermal drawing that was placed separately.
When Jiang Feng's sharp gaze swept over, the figure had already nonchalantly pushed the cleaning cart and disappeared around the corner of the corridor. Only the wheels rolling over the cement floor made a slight, rhythmic sound, like some kind of ominous melody.
