Chapter 117 Active Vibration Reduction System
Before the shock of the audience had subsided, Su Chen had already begun the next segment of the presentation.
The image on the big screen switched again, and a brand new video began to play.
What appears in the picture is not a drone, but a brightly colored hummingbird.
"Huh?"
Many people at the scene looked surprised – why was a nature documentary being shown at the press conference?
In the video, a hummingbird is seen hovering in front of a blooming flower, sipping nectar. The footage, shot with a high-speed camera, clearly shows the hummingbird's wings vibrating more than fifty times per second.
But what's most shocking is—
Although the hummingbird's wings were flapping wildly, its head and body remained as steady as a mountain!
Even with a gentle breeze and swaying flowers, the hummingbird's body remains precisely in the same position, with a deviation of no more than millimeters.
Even more astonishing is that when a sudden strong gust of wind blows, the hummingbird's wings adjust their angle and frequency in less than a hundredth of a second, allowing its body to regain its original position.
"I believe very few people have ever closely observed the flight of a hummingbird."
Su Chen's voice slowly echoed on the screen:
"The hummingbird is the most perfect hovering aircraft in nature. Its wings beat fifty to eighty times per second, yet its body remains almost perfectly still."
Why? Because the hummingbird's brain senses changes in airflow in real time at an extremely high frequency, and then adjusts the angle, frequency, and amplitude of its wings within milliseconds—these fine-tunings are so small they are almost invisible to the naked eye, but it is precisely these invisible fine-tunings that allow the hummingbird to maintain perfect hovering in any wind condition.
At this point, Su Chen changed the subject:
"Our Flying Bird S1's OIS active vibration damping system works on the same principle as the hummingbird's flight control."
The screen was divided into two halves – the top half showed a slow-motion image of the hummingbird hovering, while the bottom half showed an animation of the working principle of the S1's OIS system.
The animation clearly demonstrates three levels of vibration reduction mechanisms:
"The first layer—a MEMS gyroscope array—senses vibrations, much like a hummingbird's vestibular system senses changes in airflow. Our three gyroscopes simultaneously collect triaxial vibration data at a frequency of four thousand times per second, and noise is eliminated through cross-validation to ensure the accuracy of vibration sensing."
"The second layer—the magnetic levitation damping support—actively counteracts vibrations, much like the fine-tuning of a hummingbird's wings to counteract wind. When the gyroscope detects vibration, the magnetic levitation support generates opposing and equal magnetic forces within 0.01 milliseconds—if the vibration is to the left, the magnetic force pushes to the right; if the vibration is upward, the magnetic force pulls downward—eliminating the transmission of vibration to the core sensor at its source."
"The third layer—the active vibration damping chip and the EIS predictive algorithm work together. EIS is responsible for 'prediction'—predicting the disturbances that the flight platform may experience within 0.05 seconds in the future; OIS is responsible for 'execution'—completing the hardware-level vibration damping compensation the instant the disturbance arrives."
"The three layers of protection work in a progressive manner, much like the perfect coordination of a hummingbird's vestibular system, wing muscles, and brain neural circuits."
"Whoosh—"
The audience erupted in enthusiastic applause and gasps of amazement once again.
"So that's how it is!" Chen Weiguo slapped his thigh. "No wonder the flight footage was so stable!"
The hummingbird analogy is so intuitive—everyone has seen birds fly and understands the concept of "wings moving while the body remains still." Su Chen's use of the hummingbird to explain the OIS active vibration damping system instantly made this seemingly complex technology easy to understand.
The magnetic levitation shock-absorbing micro-support is the "hummingbird wing" of the Flybird S1—using invisible fine-tuning to combat invisible vibrations!
"But the surprises of the Asuka S1 don't stop there."
Su Chen's words silenced the entire room once again.
The large screen switched to another area of the Flying Bird S1 module disassembly diagram—the two main control chips placed side by side in the center were highlighted.
"Attentive readers may have already noticed that the Flying Bird S1 has two main control chips, instead of the single chip found in traditional flight controllers."
"Some might ask: Why use two? Isn't one enough?"
Su Chen smiled slightly:
"One is certainly enough. But enough and safety are two different things."
"The Flybird S1 employs a dual-redundant flight control architecture—two main control chips operate simultaneously with completely independent flight control systems. Under normal circumstances, the main chip handles all flight control calculations, while the secondary chip synchronizes all data in real time and is in a hot backup state."
"If the main chip fails for any reason—"
Su Chen emphasized:
"The secondary chip seamlessly takes over all flight controls within five milliseconds! The pilot will not feel any jerking, any deviation, or any loss of control—the aircraft will continue to fly smoothly as if nothing happened!"
Five milliseconds?
Cheng Weiyuan's pupils contracted slightly.
He knew better than most people present what a five-millisecond failover time meant in the aviation industry.
The dual redundancy switching time of flight control systems in commercial airliners is 20 to 50 milliseconds—which is already the world's most advanced level of avionics.
Su Chen said five milliseconds.
The flight control redundancy switching speed of a small drone is almost ten times faster than that of a commercial airliner?
What does this dual-redundancy architecture mean for the industry?
Su Chen looked at the thoughtful faces below the stage and said:
"It means safety."
"This means that drones equipped with the Feiniao S1 can truly operate in low-altitude urban areas—performing tasks such as logistics delivery, emergency rescue, and urban patrol over densely populated urban areas."
"For urban low-altitude operations, safety isn't just a matter of 99 points—it has to be 100%. And the dual-redundant flight control architecture is our 100% solution."
Applause erupted once again like a tidal wave.
Chen Weiguo clapped his hands vigorously, his eyes welling up with tears.
He recalled the drone that crashed in Ganzhou last month—if it had been using the Feiniao S1 dual-redundant flight controller, even if the main flight controller chip malfunctioned due to electromagnetic interference from the high-voltage line, the secondary chip could have taken over within five milliseconds, and the drone wouldn't have crashed, thus avoiding the loss of tens of thousands of yuan.
For these people who work in the field every day, the word "safety" carries immense weight.
"good--"
Su Chen slightly raised his hand, and the large screen switched to the feature display page of the Flying Bird S1:
"In addition to the core technologies just demonstrated, the Asuka S1 also features six built-in flight modes—"
Six icons and descriptions pop up on the screen in sequence:
Precision hovering mode: Centimeter-level fixed-point hovering, suitable for scenarios such as precision measurement and high-altitude fixed-point delivery.
Flight route inspection mode: Automatic flight along preset routes, supports resume flight after interruption and real-time route modification, suitable for scenarios such as power line inspection and pipeline inspection.
Formation Coordination Mode: In conjunction with H-Link communication base stations, a single base station can command a formation of up to forty aircraft, suitable for large-scale plant protection operations, formation performances, and other scenarios.
Emergency return-to-home mode: Automatically returns to home along the shortest safe path after communication is interrupted, avoiding obstacles throughout the process, making it a safety backup for all flight scenarios.
Terrain following mode: It uses a visual sensor to identify terrain undulations in real time and automatically adjusts the flight altitude to maintain a constant distance from the ground, which is suitable for scenarios such as agricultural plant protection and geographic surveying.
Nighttime operation mode: Infrared-assisted positioning + enhanced IMU navigation, suitable for nighttime inspection, emergency search and rescue and other scenarios.
Each mode demonstration is accompanied by video clips of actual flights, resulting in professional and stunning visuals.
The audience at the scene became more and more excited as they watched – these six modes covered almost every application scenario they could think of!
"Next—"
Su Chen slightly raised his hand, and the screen switched to the pricing page for the Flying Bird S1.
Feiniao S1 Flight Control and Communication Integrated Module: 1299 yuan
(Includes H-Link 2.0 communication baseband, EIS electronic attitude compensation, OIS active vibration reduction, dual-redundant flight control, six flight modes, and BeiDou/GPS dual-mode positioning)
The entire room fell silent for a moment.
Then--
"What?!"
Nearly a thousand people exclaimed in disbelief almost simultaneously!
1299 yuan?
So many cutting-edge technologies, such terrifying performance, a flagship module integrating a communication baseband and dual-redundant flight control—only 1299 yuan?!
It's worth noting that a single industrial-grade flight control board on the market currently costs between five and eight thousand yuan, and adding a decent communication module would cost an additional ten thousand yuan!
The Asuka S1 integrates flight control, communication, navigation, and vibration reduction into a single palm-sized module, and it only costs 1299 yuan?!
This isn't about selling products, it's about doing charity!
Chen Weiguo was at a loss for words. He just kept looking at the number, making sure he hadn't misread it.
The power company inspector next to him was already pulling out his phone: "Give me a hundred yuan! No, two hundred yuan!"
"How many airplanes do you plan to build with two hundred modules?" Chen Weiguo was speechless.
"Stock up now! At this price and with this performance, I'd still think it's a bargain even if it doubled in price next year!"
Similar conversations echoed throughout the audience.
The VIPs in the front row had various expressions—
Han Shijie smiled; the H-Link licensing agreement he signed three days ago now seemed like a gold mine.
Chen Jiaming's face was ashen. DJI's FlightCore flight controller module costs around 6,000 yuan, and its performance is not even as good as the Flying Bird S1. The price of 1299 yuan means that Hongyuan does not intend to make too much money on hardware at all - their goal is the ecosystem.
Cheng Weiyuan had filled his notebook with densely packed technical parameters, his face extremely grave.
Liu Boyuan of Hangxindatong had already put down his phone—he didn't even know how to describe what was happening to He Zhiqiang.
And Xia Kanghao—
The man, who had been expressionless from beginning to end, finally twitched the corner of his mouth slightly.
It wasn't a laugh, but a bitter sense of helplessness.
Haotai Capital has invested hundreds of millions in the low-altitude economy sector, and its strategy is undeniably profound. But Su Chen is like a madman wielding a bulldozer, barging into a meticulously arranged chessboard and scattering all the pieces.
"alright--"
Su Chen's voice rang out again, but this time his tone had changed noticeably.
No longer the calm and composed demeanor of a product launch, but rather an barely suppressed excitement and solemnity.
"All three products have been released. The H-Link Pro air-to-ground communication base station is priced at 2999 yuan, the H-Link Lite air-to-ground communication base station at 999 yuan, and the Feiniao S1 flight control and communication integrated module at 1299 yuan."
But as I said before—
Su Chen's gaze swept across the entire room, and under the watchful eyes of hundreds of people, he took a deep breath:
"I have some special news to announce."
The entire room fell silent instantly.
Even the air seemed to freeze.
Su Chen turned to face the big screen and clicked on the last page.
Two huge company logos appeared on the screen—
On the left is the bird logo of Hongyuan Intelligent Technology.
On the right is the blue shield logo of Lianchuang Group.
Between the two logos is a line of striking gold lettering—
Comprehensive strategic cooperation
Today, I officially announce—
Su Chen turned around to face the entire audience, his voice steady and powerful:
Hongyuan Intelligent Technology and Lianchuang Group have reached a comprehensive strategic cooperation agreement!
The entire audience erupted in uproar!
Lianchuang Group!
That giant that ranks among the top three in the field of military drones and industrial drones!
That super conglomerate that owns Zhongyi Aviation, a large drone manufacturing company with annual revenue exceeding 500 million yuan!
Su Chen actually secured a comprehensive strategic partnership with Lianchuang Group?!
"According to the cooperation agreement—"
Amidst the uproar from the audience, Su Chen continued to announce:
"First, all UAV products of Zhongyi Aviation, a subsidiary of Lianchuang Group, will be switched to the Feiniao S1 flight control and communication integrated module and H-Link communication system by the first quarter of next year."
This sentence exploded like a bombshell in the entire room!
Is Zhongyi Aviation switching its entire fleet?
Zhongyi Aviation is a recognized leader in the industrial-grade drone industry, with a product line covering multiple high-end fields such as military patrol, power line inspection, oil pipeline inspection, and emergency rescue. Once Zhongyi fully switches to Hongyuan's Feiniao S1 and H-Link systems—
This means that Hongyuan's technology will directly enter the fields of military and high-end industrial applications!
This means that the "high-end" positioning of the Flying Bird S1 will be completely confirmed - can anyone still say that something used by Zhongyi Aviation is low-end?
"second--"
Su Chen's voice became even more powerful:
"Hongyuan Intelligent and Zhongyi Aviation will jointly establish the 'Hongyi Low-Altitude Communication Laboratory' to jointly develop next-generation low-altitude communication standards and products, and will jointly invest no less than 150 million yuan in research and development over the next three years."
150 million!
Everyone present gasped.
For a company like Hongyuan, whose annual revenue has just exceeded 100 million yuan, a joint R&D investment of 150 million yuan is simply a gamble. But with the backing and funding of Lianchuang Group, this gamble suddenly becomes very reasonable.
"third--"
Su Chen took a deep breath and said the last thing:
"Zhongyi Aviation, a subsidiary of Lianchuang Group, plans to invest in Hongyuan Intelligent through capital increase and share expansion. The specific plan will be officially announced after due diligence is completed."
Although this was stated subtly, everyone in the know understood it perfectly—
Lianchuang Group is going to invest in Hongyuan Intelligent!
It's not a simple business partnership, but a deep integration at the capital level!
The atmosphere in the entire venue instantly reached a boiling point!
Applause, exclamations, and murmurs mingled together, making the entire convention center seem to be ablaze.
Just then—
In the middle of the third row of the VIP section, a burly middle-aged man slowly stood up.
All eyes in the room were instantly drawn to it.
Zhou Zhenguo, Chairman of Lianchuang Group.
The person who changed their flight from the United States three days ago and traveled thousands of miles back.
At this moment, everyone finally understood why Zhou Zhenguo had rushed back from the United States to attend a "Flying Bird 2.0 Technology Open Day".
Because this isn't some kind of technology open day.
This is the oath-taking ceremony where Hongyuan Intelligent and Lianchuang Group announced their alliance.
Zhou Zhenguo turned to face the entire audience, bowed slightly, and then spoke in his signature deep voice:
"The collaboration between Lianchuang Group and Hongyuan Intelligent is the most important decision I've made in my 30 years in the industry."
His gaze shifted to Su Chen on the stage, his eyes filled with genuine admiration:
"Su Chen, this young man, has shown me the future of China's low-altitude economy. Lianchuang Group is willing to dedicate all the resources accumulated over thirty years to working with Hongyuan Intelligent to define this future."
The applause erupted like a tsunami.
More than 900 people stood up and applauded, some even with tears in their eyes.
Amidst the thunderous applause, Chen Weiguo also stood up and clapped vigorously.
Although he was just an entrepreneur with a small team of twenty people, insignificant in this venue, at that moment he truly felt—
Today's press conference is rewriting the history of China's low-altitude economy.
Su Chen, who was standing on the stage, was the writer.
……
The applause lasted for a full two minutes before gradually subsiding.
Su Chen stood in the center of the stage again, his eyes filled with something he hadn't seen before—not pride, but a heavy sense of mission.
Finally, I'd like to say a few more words.
The entire room fell silent once again.
"Some may ask—why is Hongyuan opening up the H-Link protocol framework? Why sell hardware at such a low price? Why share our core technology with other companies?"
Su Chen's gaze swept across the entire room:
"This question is like asking—why distribute the seeds to everyone instead of keeping all the food for yourself?"
"Because a single seed left in a warehouse will forever remain just a single seed. But if you plant it in a thousand plots of land, the following year it will yield a thousand acres of harvest."
"H-Link is not just a communication protocol. It's a standard, an ecosystem, and an infrastructure."
"Today, Mr. Han Shijie, General Manager of Xingyao Technology, obtained H-Link's protocol development-level license. Tomorrow, more companies may join in—communication module manufacturers, drone manufacturers, industry application developers, chip design companies…"
"When all low-altitude air traffic control companies in China are developing products based on the H-Link framework, when all drones in China are using the H-Link protocol for communication—"
Su Chen's voice became firm and powerful:
"At that time, H-Link was no longer just a technology of Hongyuan, but the cornerstone of China's entire low-altitude economy."
"This is our goal—not to be a profitable company, but to build a fundamental standard for the industry."
After saying this, Su Chen bowed deeply.
The applause erupted once again like a tidal wave.
But this applause was different from any before.
The previous applause was a reaction to the shock of the technology, the excitement about the price, and the thrill of the collaboration.
And this time, the applause—
It is a heartfelt tribute to a vision and a framework.
……
Within half an hour of the press conference ending, the corridors of the convention center were bustling with noise.
Dozens of business owners rushed to Hongyuan Intelligent's exhibition area, eager to get product information and pre-order channels as soon as possible.
The first batch of 3,000 H-Link Lite units sold out in less than 15 minutes after the launch event. The first batch of 1,500 H-Link Pro units also sold out within half an hour. Pre-orders for the Flybird S1 exceeded 5,000 units within an hour—far surpassing Hongyuan's initial production capacity.
At the other end of the corridor, Chen Jiaming and Wang Rui were walking briskly towards the parking lot.
Chen Jiaming's phone had already connected to the Shenzhen headquarters: "Convene an emergency technical review meeting immediately. I'll be there in two hours. There's only one agenda item—a complete reassessment of FlightCore's next-generation technology roadmap."
Meanwhile, Cheng Weiyuan of Huawei's Low-Altitude Intelligent Connectivity Lab had already boarded a business vehicle returning to its headquarters in Songshan Lake, Dongguan. While organizing his densely packed notes, he made a phone call to HiSilicon Semiconductor in Shanghai.
"Hongyuan's communication chip technology is at least a year and a half ahead of ours." His voice was calm but serious. "I suggest accelerating the development of low-altitude communication chips; the budget needs to be increased by fifty percent."
In another corner of the parking lot, Liu Boyuan of Hangxindatong was leaning against the car door, making a phone call to He Zhiqiang in Beijing.
"President He, the situation... is much more serious than we anticipated."
There was a long silence on the other end of the phone.
"How much does he price his base stations?"
999.
Another silence followed.
"We'll talk about it when we get back."
The phone hangs up.
Liu Boyuan shook his head with a wry smile and started the engine.
He knew that from this day forward, the LDCL standard's dominance in the low-altitude communication market had been completely shattered. Hangxindatong's proud monopolistic standard barrier had become a joke in the face of Hongyuan's H-Link.
……
In the last row, in a corner, Xia Kanghao quietly left the venue.
No one noticed him, and no one cared about his departure.
But as he stepped out of the convention center and stood under the scorching July sun in Shenzhen, he took out his phone and dialed a number.
"Get ready, I need to reassess Haotai's entire portfolio in the low-altitude sector."
He paused for a moment, then added:
"Also—check if Hongyuan Intelligent currently has any open investment opportunities."
After saying this, Xia Kanghao himself was slightly taken aback.
If you can't beat them, join them?
He gave a wry smile, put on his sunglasses, and disappeared into the crowds in Nanshan, Shenzhen.
