Multirotor UAV for Firefighting
The Multirotor UAV for Firefighting is a modular, VTOL aerial suppression system designed for complex fire scenarios in forests, high-rises, and industrial zones. With a max take-off weight of 145 kg (320 lb) and endurance up to 60 minutes, it delivers precision fire-extinguishing payloads from 20+ meters (65+ ft) away, covering up to 300㎡ (3,230 ft²) per strike. The platform supports full customization across propulsion (oil/electric), flight control, rotors (2–6), and payload modules, ensuring operational flexibility. Its rugged structure, dual-sensor targeting, and autonomous flight features make it ideal for rapid, safe deployment in high-risk environments.
Flarenix Firefighting Multirotor UAV
Built to meet the demanding standards of modern aerial firefighting, the Multirotor UAV integrates industrial-grade fire suppression systems with mission-ready autonomous avionics. It supports real-time mission planning, dynamic reprogramming, and customized geofencing, enabling safe operation in dynamic airspaces.
The core structure uses aviation-grade aluminum alloy, designed for rapid deployment via foldable arm architecture and fast-locking landing gear, with total ground setup time under five minutes. Payloads—up to 13 extinguishing bombs (up to 4 kg/8.8 lb each)—are mounted using high-tensile quick-release brackets, vibration-tested to ISO 16750 standards to ensure in-flight reliability.
The dual-sensor gimbal (visible + IR thermal, 640 resolution) supports temperature-based fire source targeting, while the onboard AI-enhanced imaging system assists in auto-locking hotspots, enhancing bomb-drop accuracy in dense smoke or obstructed terrain.
Command & control is available via encrypted dual-band communication (>10 km / 6.2 mi range), and the system is compliant with FCC radio emission regulations and FAA Part 107 visual line-of-sight standards. The vehicle integrates with most US public safety platforms via standard API and supports secure integration with NFPA-compliant suppression agents.
The heavy-duty twin-screw variant expands capabilities with 140 kg (309 lb) payload, 3–4 hour endurance, and an open payload bay that accommodates firebomb clusters, emergency supply containers, or custom modules for reconnaissance, communications, or simulation equipment.
