Firefighting scenarios in urban high-rise buildings
Scene Pain Points
Current rotorcraft‑type firefighting drones suffer from inadequate fire‑extinguishing capabilities, with liquid flow rates below 3 L/s. Meanwhile, conventional aerial ladder trucks face limitations such as restricted working heights, slow response times, and low firefighting efficiency—none of which can effectively address this global challenge.

Firefighting scenarios in urban high-rise buildings
Weihang Technology’s world‑first ducted‑fan, high‑altitude tethered main‑battle fire‑fighting drone system is an integrated product that seamlessly combines a high‑thrust ducted‑fan flight platform with a firefighting chassis. It delivers exceptional firefighting and rescue performance: while maintaining the compact dimensions of a standard fire truck—10 m × 2.55 m × 4 m—to ensure rapid deployment to the scene, it can swiftly ascend to altitudes of over 100 meters and sustain a continuous liquid flow rate exceeding 30 L/s for extended periods, providing robust fire‑suppression capabilities. This next‑generation main‑battle asset is fully capable of addressing the challenges of firefighting and rescue operations in urban high‑rise buildings.
Strong fire-extinguishing capability
With a continuous liquid‑jet flow rate exceeding 30 liters per second, it can deliver a stable, high‑volume spray at heights of up to 100 meters, achieving an effective reach of no less than 50 meters. Its firefighting performance is comparable to that of top‑tier conventional fire trucks—more than 5 to 10 times greater.
High rescue efficiency
With compact dimensions (under 10 meters), the vehicle can arrive at the fire scene alongside the first wave of firefighting forces, eliminating the need to set up complex rescue support structures. The drone can deploy and take off within three minutes and ascend to an altitude of 100 meters in just two minutes, commencing primary firefighting operations—truly enabling efficient, frontline response during the critical “golden hour.”
Dual-purpose device
The system can employ either water or compressed-air foam as extinguishing agents; the aircraft’s high‑flow water jet can reach a height of 100–150 meters, while its high‑flow foam jet can attain a height of 150–300 meters.
Highly secure
The ducted‑fan system features isolation protection and a multi‑redundant design, delivering robust wind resistance and stability to ensure safe flight and operations at fire‑fighting sites.
