Weihang Technology made its debut at the 2024 Shenzhen Safety and Emergency Technology Exhibition, spearheading a new wave of innovation in emergency equipment applications.

August 22–24, 2024 Shenzhen Safety and Emergency Technology Exhibition & Shenzhen Emergency Industry Expo Held at the Shenzhen Convention & Exhibition Center, this exhibition is themed “Developing New‑Type Productive Forces and Advancing Emergency Response Modernization,” bringing together over a hundred industry-leading enterprises to showcase the latest breakthroughs in safety and emergency‑response technologies. Weihang Technology was invited to present its most recent innovations… Ducted-fan high-altitude tethered firefighting drone system At the exhibition, the company’s founder, Li Ye, attended the 2024 Urban Public Safety Technology Joint Innovation and Application Forum held concurrently and delivered a speech titled “…”. Introduction to Typical Applications of Ducted-Fan eVTOLs in the Emergency Response Sector Keynote speech.

The ducted-fan, high-altitude tethered firefighting drone system is based on Weihang Technology’s innovative technological breakthroughs in the most critical subsystem of electric aircraft—the power propulsion system— Electric ducted-fan propulsion technology A cross‑disciplinary, technology‑driven innovation product that integrates the two strategic emerging industries of safety and emergency response and the low‑altitude economy.

This product fully leverages the unique advantages of electric ducted-fan technology—smaller size, greater thrust, lower noise, and enhanced safety—compared to electric rotor technology. By seamlessly integrating an electric ducted-fan flight platform with existing firefighting chassis vehicles and fire-extinguishing equipment, it enables the realization of… The fire truck’s overall dimensions are only 10 × 2.55 × 4 meters. , at a height of 100 meters and with 30L/s Continuous fluid flow of Its robust long‑duration firefighting and rescue capabilities combine the high efficiency of modern firefighting drones with the superior fire‑extinguishing power of traditional fire trucks, thereby comprehensively addressing the global challenge of inadequate, effective real‑world equipment for fire suppression and rescue in urban high‑rise buildings, and becoming… Next-generation primary firefighting equipment for urban high-rise buildings.

As the sole dedicated aerial firefighting platform, it immediately drew the attention of emergency management bureaus, fire departments, and numerous partners and suppliers from across the country upon its debut.

After thoroughly reviewing our product’s performance specifications, a city fire department expressed great surprise: “Our primary concern when it comes to firefighting equipment for high-rise buildings is water‑flow rate. If your ducted‑fan drone can deliver a firefighting water flow of 30 L/s, it could undoubtedly become a core piece of main‑battle equipment!” An emergency management bureau likewise remarked: “Based on your product’s standards, once it hits the market, it will inevitably replace much of the firefighting gear we currently use.” Meanwhile, a forest fire‑fighting unit also voiced strong approval of our product, expressing hope that it would be brought to market promptly and that further exploration of forest‑fire scenarios could soon follow.

Many long-time partners and suppliers in the emergency response sector have expressed keen interest and a strong willingness to collaborate, urging us to expedite the fabrication and testing of the first prototype while also suggesting additional application scenarios. One wind‑power O&M company stated: “Our company specializes in the operation and maintenance of wind turbines. Since these turbines are typically installed at high altitudes, transporting the equipment needed for installation and routine maintenance each year is extremely challenging—time‑consuming, labor‑intensive, and costly. If we could deploy a heavy‑payload drone like yours to deliver equipment directly from lower elevations to their intended high‑altitude locations, it would significantly reduce our expenses.”

At the 2024 Joint Innovation and Application Forum on Urban Public Safety Technologies, held concurrently with the exhibition, Li Ye, founder of Weihang Technology, delivered a keynote speech titled “Typical Applications of Ducted-Fan eVTOLs in Emergency Response,” offering a fresh perspective and innovative solutions for urban high-rise building fire scenarios. He noted: “Currently, among aviation‑based firefighting equipment, fire‑fighting helicopters are too large, while multirotor firefighting drones have insufficient payload capacity—both can only provide auxiliary support for early‑stage, small‑scale fires. There is an urgent need to develop…” A main‑combat firefighting drone with enhanced fire‑extinguishing capability, improved safety, a more compact footprint, advanced intelligence, and greater specialization. 。” WeiHang’s innovative products can enable For the first time, drones have acquired the capability to conduct main‑battle firefighting. and has been further explored and applied in scenarios such as forest‑grassland ecosystems, petrochemical facilities, photovoltaic power stations, emergency rescue operations, and smart fire‑fighting systems.
