Chapter 30 The Firecrackers Prepared for Eagle
In response to that damned comic, and to prove a point, the entire 091 base was operating at full speed, as if it had been injected with adrenaline.
The missile test launch program, codenamed "Dongfeng," was immediately elevated to the highest priority.
That was the "big firecracker" that Commander Zhang mentioned, and it was also the culmination of the hard work of thousands of people in the entire base.
However, things did not go as smoothly as expected.
Although the super fuel provided by Zhao Di solved the problem of insufficient thrust.
Although Zhao Di repaired the machine tool, it solved some of the parts processing problems.
However, one core component became a stumbling block.
That's the gyroscope inside the seeker head.
This thing is the missile's "eyes" and "cerebellum".
No matter how fast or far a missile flies, if it's inaccurate, it's useless; it's like a blind man or a headless fly.
To expect it to hit exactly where you point it is a pipe dream; it might just fly out, spin around, and fall back onto your head.
In the underground laboratory of the research building.
Chen Zhiyuan and a group of veteran experts have been working tirelessly for three days and three nights.
The floor was littered with cigarette butts, and the room was filled with smoke that made it hard to open one's eyes.
Several discarded gyroscope models were laid out on the table, each representing a failure.
"No, it still won't work."
Professor Wang, who was in charge of precision instruments, threw the vernier caliper in his hand onto the table, took off his glasses, and rubbed his red eyes.
"Our materials are fine, and the processing precision is barely enough."
"But no matter how I adjust the dynamic balance, I can't get it right."
"As the rotational speed increases, the error increases exponentially."
"With this level of precision, even if a missile flies a thousand kilometers, the error could be off by a mile."
"Let alone shooting across the ocean, even hitting the target range next door is a struggle."
Chen Zhiyuan sighed, looking at the gyroscope that was still trembling slightly, and felt a wave of despair.
This technique is their specialty.
When the Soviet experts left, they burned all the blueprints, leaving not a trace.
We're feeling our way across the river, figuring things out on our own.
But time waits for no one.
Commander Zhang has already made a pledge to complete the test launch by next month.
If the missile misses its target, it will truly become a joke in American cartoons.
"Old Chen, how about... we go and beg Zhao Di again?"
Someone suggested in a low voice.
Chen Zhiyuan gave a wry smile.
"Zhao Di is indeed a genius, but she is still a child after all."
"This gyroscope involves complex mechanical balance and inertial navigation principles."
"We old folks have been trying to figure this out our whole lives and we still can't. Do you really expect a three-year-old to make it by hand?"
Although Zhao Di had created many miracles before.
But this time it's different.
This is the pinnacle of precision manufacturing; it's not about playing with mud or mixing paints.
Just as these old men were filled with gloom and despair.
The laboratory door was pushed open.
Lin Jianguo carried Zhaodi in.
He came to deliver food to Old Chen.
Zhao Di wore a red cotton-padded jacket with white flowers today, which looked very festive.
She was holding a small wooden trinket in her hand, engrossed in playing with it.
"Old Chen, have something to eat first, don't ruin your health."
Lin Jianguo placed the lunchbox on the table, frowned as he looked at the room filled with smoke, and subconsciously fanned Zhao Di.
Chen Zhiyuan had no appetite.
He waved his hand, about to say he wasn't hungry.
Sudden.
His gaze fell on the little gadget in Zhao Di's hand.
It was a spinning top made of wood.
It looks ordinary, even a bit rough, just a toy for children.
Zhao Di slid down from her father's arms and walked with her short legs to the smooth marble table in the middle of the laboratory.
"Grandpa, are you spinning around in circles?"
Zhao Di looked at the still-vibrating metal gyroscope on the table and asked curiously.
"Yes, Grandpa is spinning around."
Chen Zhiyuan mustered his spirits and patted Zhao Di's head.
"It's a pity Grandpa is clumsy and can't turn it steadily."
"Grandpa is silly."
Zhao Di giggled and placed the wooden top in her hand on the table.
"Look at Zhao Di!"
"Zhao Di's spinning top is the most obedient!"
As she spoke, the little girl stretched out her thumb and forefinger, pinched the small handle of the spinning top, and twisted it hard.
"call--"
The wooden top started spinning instantly.
Chen Zhiyuan originally just wanted to appease the child and didn't take it seriously.
But, the moment the top started spinning.
His eyes widened.
That wooden top, spinning at high speed, actually...
It was as if it had frozen in time!
It stood motionless on the smooth marble countertop.
There was not a slight tremor, not a single displacement.
You can't even hear the sound of the wind from the rotation.
If the pattern on it hadn't turned into a blurry, indistinct image, Chen Zhiyuan would have thought it was stuck to the table!
"this……"
Chen Zhiyuan abruptly took off his glasses, wiped them vigorously, and then put them back on.
He lay on the table, his face almost touching the spinning top.
Staring intently.
One second, two seconds, one minute...
The spinning top remained as steady as a mountain.
This stability, this dynamic balance...
This completely defies the common sense of physics!
Even if they used the most sophisticated machine tools to machine a metal gyroscope, they could not achieve this level of "stillness"!
"Old Wang! Old Li! Come quick!"
Chen Zhiyuan's voice was trembling, as if he had seen a ghost.
The group of old experts who had been sighing were startled by the shout and quickly gathered around.
When they saw that wooden spinning top that seemed frozen in time.
Their jaws nearly dropped to the floor.
"My God... what kind of divine dynamic balance is this?!"
"How was the center of gravity found? How was the mass distribution calculated?!"
"That's impossible! Wood is a material with uneven density, how could it possibly spin so steadily?!"
Everyone went crazy, bringing all sorts of testing equipment.
A dozen laser vibration meters.
The readings show that the vibration amplitude is close to zero!
what does that mean?
This means that this unassuming wooden gyroscope is at least a hundred times more accurate than the metal gyroscopes they are currently developing!
A hundred times!
What does this mean?
This is a leap from homemade cannons to intercontinental ballistic missiles!
“Zhao Di…”
With trembling hands, Chen Zhiyuan pointed at the still-spinning top, his tone filled with awe.
"You...made this?"
Zhao Di was leaning over the table watching the commotion when she heard her grandfather ask, and she nodded.
"Mmm!"
"System... oh no, it was the fairy uncle who taught me how to shave."
Actually, this was a "handicraft assignment" that the system released a couple of days ago.
The system gave her a nanoscale carving knife (disguised as an ordinary knife) and a perfect geometric model.
Zhao Di carved it out piece by piece, following the model.
In her eyes, it was just a toy.
"My uncle said that if you cut off a little bit of the meat on this side and a little bit of the meat on that side, it will keep spinning and spinning until it gets dark and it won't fall over."
Zhao Di gestured, her face full of innocence.
"Grandpa, is this fun?"
"It's so much fun...it's so much fun..."
Chen Zhiyuan was at a loss for words.
He looked at the wooden top as if it were a savior.
Is this the intuition of a genius?
No formulas or calculations are needed; you can find the perfect center of gravity simply by making a few cuts based on your intuition.
This is absolutely a game-changer!
"Quick! Map out this structure!"
Chen Zhiyuan suddenly came to his senses and shouted loudly.
"Based on the geometric parameters of this wooden top, we will use our special steel to replicate it one-to-one!"
"Even if we just copy the design, we can still create the most stable gyroscope in the world!"
The entire laboratory instantly erupted in excitement.
Everyone was like they'd been injected with adrenaline, grabbing calipers and microscopes and frantically measuring the little wooden toy.
Some people were so excited that they wanted to kowtow to the spinning top.
Lin Jianguo stood aside, watching this scene, completely dumbfounded.
He looked down at his daughter in his arms.
"Girl, what kind of wood is that?"
"It's that dead poplar tree by the entrance."
Zhao Di blinked and pulled another identical little spinning top out of her pocket.
"Dad, this is for you to play with."
"Spinning it around can relieve stress."
Lin Jianguo took the little gadget, his hands trembling slightly.
Although he didn't understand technology, he knew it.
The little bit of sand that slips out of my daughter's hand could really fill the sea!
Three days later.
The first metal gyroscope, modeled after Zhao Di's "wooden toy," officially rolled off the production line.
Assembly, testing, and integration.
Everything went so smoothly it was unbelievable.
When the gyroscope was spinning at high speed on the test bench, all its performance indicators exceeded the maximum.
Chen Zhiyuan hugged the cold, metallic lump and cried like a child.
"It's done...it's done..."
"Our firecrackers have eyes now!"
"This time, we'll hit wherever we're told!"
"We can smash even the American president's coffee cup!"
When Commander Zhang arrived after hearing the news, he saw this group of old men embracing each other and weeping.
He looked at the gyroscope that was spinning silently.
Then she looked at Zhao Di, who was sitting on a high stool, swinging her legs and eating candied hawthorn.
Commander Zhang took a deep breath and gave Zhao Di a thumbs up.
"Good girl!"
"Grandpa thanks you on behalf of the entire army!"
"This time, the gift we've prepared for the US is quite substantial!"
Zhao Di took a bite of the candied hawthorn and squinted her eyes because it was so sour.
"Grandpa, is there candy in the gift bag?"
"have!"
Commander Zhang laughed heartily, his laughter revealing an unprecedented sense of pride.
"It's not just about sugar, it's also about the backbone of the Chinese people!"
"This time, we'll let the whole world hear what the roar of the Eastern dragon is all about!"
