The report first notes that in May of this year "Ao Qin" A new round of performance upgrades has been completed, optimizing the motor and electronic control systems, hybrid‑power energy management, and flight‑control capabilities, while simultaneously enhancing the platform’s payload capacity and stability. Following the upgrade, Ao Qin… 100 meters The height of the water spray flow reaches 30.9 liters per second , effective spray distance 45 rice Above, net payload 500 kilograms ， Its firefighting capability has surpassed that of 100-meter-class aerial ladder fire trucks. Water-spraying operations cover a range of 0 to 150 meters, while foam coverage extends from 0 to 200 meters.
Li also noted that this upgrade has achieved numerous critical technological breakthroughs, with the ducted-fan propulsion unit featuring a higher‑aspect‑ratio three‑dimensional twisted blade design, delivering greater thrust at the same rotational speed. Increase by more than 20% , force efficiency Increased by approximately 5%. Regarding the principles of fire suppression in high-rise buildings, the report notes that such fires are prone to the chimney effect, necessitating the establishment of smoke-exhaust and extinguishing-agent‑delivery channels above the neutral plane. Under these conditions, the extinguishing agent must overcome substantial pressure differentials between the interior and exterior of the walls, penetrating upward through hot smoke, thermal plumes, and complex external wind fields. In this scenario, low‑density extinguishing media—such as foam or low‑pressure, small‑volume water streams—or fine droplets lack sufficient momentum, exhibit poor penetration, and are easily disrupted by reverse‑flowing smoke and ambient air currents, making it impossible to deliver an adequate, sustained dose of extinguishing agent deep into the fire zone. Consequently, only high‑momentum, high‑flow water jets can surmount these pressure differentials and penetrate the opposing airflow, thereby constituting the primary firefighting force. To address this challenge, the upgraded “Aoqin” system employs high‑pressure, high‑flow water jets to generate a high‑momentum main‑battle stream, enabling operations at heights of up to one hundred meters. Over 30L /s Continuous operation of water flow 。
This August, “Aoqin” conducted tactical and operational research tailored to various scenarios, with a focus on real-world applications, and successfully completed a series of field validations. In terms of tactics, during live‑fire testing, “Aoqin” demonstrated that upon arriving at the scene… 1 minute 58 seconds Complete deployment, 16 seconds It can spray water as soon as it is raised; by contrast, the DG70 aerial platform fire truck used in the same comparative test took about 7 minutes. Based on the high mobility and stability of the “Aoqin” fire‑extinguishing equipment, a model is constructed according to the trajectory of the extinguishing medium. Z, N, I, O Four basic fire‑extinguishing tactics, tailored to the needs of different firefighting scenarios, include interior‑attack water supply, spray‑type protection for personnel, Effective innovative tactics such as long-range deployment 。
During the live-fire test phase, the exercise simulated a sudden fire breaking out on the sixth-floor balcony of a high-rise building, with the building’s fire load reaching as high as 650 MJ/㎡ , under the influence of intense thermal convection, the fire rapidly spread upward, quickly igniting the living rooms and bedrooms of adjacent units on the seventh floor, with the temperature at the fire’s epicenter reaching 830℃ , After receiving the emergency call, Ao Qin skillfully employed tactics and methods—including high-altitude precision reconnaissance, pinpoint suppression of the fire, layered three-dimensional firefighting, and sustained, efficient fire control—using only 3 minutes This effectively prevents the fire from spreading across floors, 5 minutes The open flames were completely extinguished, thoroughly validating the unique advantages of the main combat firefighting drone and the operational effectiveness of the preliminary tactical and doctrinal research.
In addition, Li also mentioned that Weihang Technology is advancing… A Real-Time Prediction Framework for Firefighting Processes Driven by Large-Scale Models Drone‑borne multi‑sensor systems perceive the fire scene, while a large‑scale model performs data fusion and scene understanding. It dynamically couples a fire‑development model with a firefighting‑action model, generating real‑time predictions of the evolving fire situation under intervention, thereby providing decision‑making support for on‑site command. Real‑world fire‑scene data accumulated through operational practice continuously feeds back into theoretical research on “firefighting dynamics,” establishing an iterative “fire–water–tactics” closed loop that integrates data, models, and theory, steadily enhancing practical firefighting capabilities.
Guest Interview
During the conference, on-site interviews were conducted, focusing on the key challenges in extinguishing fires in high-rise buildings and Ao Qin’s proposed strategies for addressing them. Li also stated that, when conducting firefighting operations in high-rise building fires, drones must primarily contend with the severe airflow disturbances caused by the chimney effect and intense thermal radiation. This places extremely high demands on the high-pressure, long-range jetting capability of firefighting equipment. Moreover, the superimposed effects of complex airflow and the high‑pressure, high‑flow water jet’s reaction force demand that the UAV possess stable hover capability for sustained operations. With a takeoff weight of 900 kg and a substantial 500‑kg payload, Ao Qin can counteract the substantial lateral recoil of strong water currents; by utilizing tethered power and fluid supply, it achieves stable hovering at altitudes of up to 100 meters while generating high‑momentum, high‑velocity water jets capable of penetrating long distances. This makes it an exceptional aerial primary firefighting platform for delivering continuous, high‑intensity suppression against fires in high‑rise buildings.
Meeting venue
Outside the venue, scale models such as the “Aoqin” drew crowds of attending experts, who paused to examine key components like the ducted-fan propulsion unit. A lively discussion ensued, focusing on ducted‑fan aerodynamic design, load‑carrying configurations, and real‑world deployment procedures. The physical presentation of the models, coupled with dynamic footage of firefighting drills, made the technological advances highlighted in the academic presentations tangible and readily comprehensible.
