Ducted-fan high-altitude tethered firefighting drone system
Weihang has innovatively applied electric ducted-fan jet propulsion technology to the emergency firefighting sector, introducing a tethered ducted-fan firefighting and emergency response platform. Powered by a ground‑based power supply via tether, the platform can maintain prolonged, sustained operations in flight.
Combat-grade, high-flow water jet
Equipped with an ultra‑large payload configuration, the system boasts a 500 kg effective payload and a maximum takeoff weight of 900 kg. At an altitude of 100 meters, it can sustain a stable water‑discharge rate of over 30 liters per second, rapidly suppressing open flames. Paired with a high‑pressure tethered power supply, it supports prolonged, uninterrupted primary firefighting operations.
High load,Large water volume,Long battery life
Supertall—Full-Height Coverage
One device, dual functionality: designed for firefighting in high-rise buildings, with a pure‑water jet range of 0–150 meters and a foam‑jet range of 0–300 meters. It accommodates different flight altitudes by matching the appropriate hose diameter—low‑altitude operations can be paired with large‑diameter hoses to enhance jet performance—and, when used with building‑specific auxiliary attachments, seamlessly integrates with 65 mm mainline hoses to deliver full‑floor, full‑height fire suppression.
Dual-purpose device,Highly compatible,Flexible work
Long-distance, high-pressure jetting
The device maintains a stable outlet pressure of 0.3–0.6 MPa, delivering robust water flow and ample jetting power, with an effective spray range of up to 50 meters. It can safely navigate high‑temperature fire environments and overcome obstacles, enabling precise long‑range firefighting.
High-voltage output,Excellent range,Long-range jetting
High efficiency · Rapid emergency response
The vehicle’s overall length is under 10 meters, ensuring excellent maneuverability and rapid response to fire scenes. On‑scene preparation takes no more than 3 minutes, and it takes no more than 2 minutes to raise the equipment to an altitude of 100 meters, significantly reducing pre‑deployment time and enabling swift deployment for emergency firefighting operations.
Compact body,Arrived promptly,High-efficiency liftoff
High Security · Multi-Redundancy Protection
Equipped with triple physical safeguards—ducted‑fan protection, redundant excess thrust, and parachute‑assisted emergency landing—the system also boasts robust anti‑interference capabilities, adapts to complex airflow conditions within buildings, and can operate in close proximity to high‑temperature fire environments, ensuring maximum overall operational safety.
Multi-layered protection,Redundant design,Strong anti-interference capability
Intelligent Multi-Machine Cluster Collaboration
Equipped with an intelligent fire‑detection system, it can autonomously assess the fire situation, support coordinated operations across multiple units, dynamically optimize firefighting strategies, and integrate crew‑supplied water flow rates, thereby significantly enhancing the efficiency of large‑scale fire response.
Intelligent recognition,Cluster operations,Diverse strategies
High Standards · Authoritative Official Qualifications
The product has been rigorously tested in full compliance with the requirements of the Shanghai Fire Research Institute of the Ministry of Emergency Management (National Center for Quality Inspection and Testing of Firefighting Equipment), and a test report has been issued by the institute.

Eight Major Firefighting Scenarios
A variety of firefighting scenarios suitable for the ducted-fan, high-altitude tethered fire‑extinguishing drone system.
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.
Firefighting,Breaking the height barrier,Three-dimensional collaboration
Firefighting scenario in a narrow urban alleyway
In areas where fire trucks cannot access—such as aging neighborhoods and historic alleyways—small drones can navigate narrow passages to reach the fire scene, conducting precise reconnaissance and firefighting.
Firefighting,Flexible traversal,Last mile
Fire protection scenarios such as smart industrial parks, chemical plants, oil and refining facilities, and photovoltaic power stations.
Modern smart parks integrate drone-based fire‑fighting and inspection systems, enabling 24/7 automated patrols, automatic early warnings for potential hazards, and rapid response coordinated with fire‑fighting equipment.
Firefighting,Automated inspection,Smart Early Warning
Firefighting scenarios involving urban supertall buildings (over 200 meters), CBD core office districts, and high-rise residential complexes.
New‑generation smart fire‑fighting system: a locally deployed smart fire‑fighting system comprising a tethered ducted‑fan aerial platform and a locally installed distributed drone hangar.
Instant response,Main battle firefighting,Smart Recognition
Air ambulance / Traffic accident rescue / Forest and grassland firefighting scenarios
For future urban emergency response, drone‑based flying cars can rapidly meet urgent rescue needs, establishing aerial emergency corridors above the city and significantly reducing response times.
Medical care,Emergency Lane,Rapid transfer
Logistics and transportation in plateau and mountainous areas, natural disaster zones, and island regions.
In plateau, mountainous, or disaster‑stricken areas where roads are blocked, multirotor drones enable rapid aerial delivery of supplies, overcoming the constraints imposed by disrupted ground transportation.
Rescue,Circuit-breaking delivery,Heavy-duty suspension
Emergency Communications
In disaster areas where communication infrastructure has been damaged, drones equipped with relay communication equipment are deployed to swiftly establish temporary communication nodes and restore emergency communication networks.
