Brief News | The “Aoqin” fire‑extinguishing system has achieved another major breakthrough, with a water‑spray flow rate exceeding 30 L/s at an altitude of 100 meters.

On May 12, coinciding with National Disaster Prevention and Reduction Day, Weihang Technology’s independently developed “Aoqin” firefighting drone successfully completed its first full‑scale performance validation test following a major upgrade, with all key operational metrics meeting the expected targets. This test not only serves as robust confirmation of the product’s iterative advancements but also aligns with the critical industry milestone of disaster prevention and reduction.

During the test, under conditions of pure water spraying, The drone successfully achieved its flight altitude. 100 meters At the same time, the effluent flow rate is as high as 30.9 liters per second ， Effective spray distance increased to 50 meters This achievement marks a quantum leap in the “Aoqin’s” firefighting performance at 100-meter altitudes, providing a more robust equipment solution to the challenges of high-rise building fires.

Currently, urban high-rise firefighting faces the challenge of a lack of effective primary firefighting equipment, as existing mainstream systems each have significant limitations. The world’s leading 100-meter‑reach aerial ladder truck—the Finnish Rosenbauer—can deliver a liquid flow rate of 30 liters per second at a height of 100 meters; however, its massive dimensions (16.3 meters long with a turning radius of 50 meters) mean it often requires several hours to reach the scene after receiving an alarm, and even the on‑site preparation—such as setting up a stable rescue platform—can take dozens of minutes, making it difficult to meet the operational demand for rapid attack and swift extinguishment in high-rise fires. Moreover, each unit carries a price tag of approximately RMB 25 million, resulting in relatively high acquisition costs. Meanwhile, the rotary‑wing firefighting drones currently available on the market, while highly maneuverable, are constrained by their payload capacity: at 100 meters altitude, they typically provide only 3–5 liters per second, and most support only foam discharge, falling short of the performance required to serve as the primary firefighting asset in high-rise buildings.

In contrast, Weihang Technology’s “Aoqin” firefighting drone boasts three core advantages: high rescue efficiency, robust primary firefighting capabilities, and exceptional safety. This equipment… With a vehicle length not exceeding 10 meters, its dimensions are comparable to those of the smallest 18-meter aerial ladder fire truck available on the market, enabling it to achieve… Within 15 minutes Arrive at the rescue site, Within 3 minutes Complete deployment, Within 2 minutes Lifted to a height of 100 meters. At this altitude, the equipment’s flow rate exceeds… 30 liters per second , with an effective spray range of 50 meters , with outstanding main battle fire‑fighting capabilities. The airframe features a ducted‑fan design that encloses the rotor blades, reducing cutting hazards while significantly enhancing flight stability and ensuring all‑round operational safety.

Addressing the persistent challenge of firefighting in ultra‑tall buildings exceeding 100 meters in height, the “Ao Qin” system can be integrated with building‑mounted hoisting devices and rail‑guided systems. By tailoring equipment configurations and supporting strategies to different height brackets, it overcomes the conventional height limitations of urban high‑rise fire suppression. Achieve full-height coverage, rapid and precise high‑volume water jetting, and sustained firefighting for ultra‑tall building fires. Thus, this systematically addresses the global challenge of insufficient primary offensive equipment for firefighting in super‑tall buildings. 。

Leveraging multiple differentiating advantages, “Aoqin” directly addresses and fills critical gaps in current fire‑fighting equipment for high‑rise buildings, bridging the void in fire rescue operations at high‑rise and super‑tall structures. It has emerged as a next‑generation, cutting‑edge firefighting force within urban emergency response systems—specifically designed to tackle high‑rise and super‑tall building fires with exceptional efficiency and decisive effectiveness.
