As demand for more precise and cost-effective weather modification continues to grow, unmanned aerial systems are increasingly being adopted as an alternative to traditional manned aircraft.
Against this backdrop, JOUAV has introduced the CW-80E, a VTOL unmanned aerial system(UAS) designed for weather modification missions, including cloud seeding and precipitation enhancement.
The CW-80E is configured to carry warm cloud flares and a cloud particle imaging payload, enabling operators to assess cloud microphysical conditions and conduct targeted seeding operations. The system operates at designated altitudes and within defined airspace, where onboard ignition can be remotely triggered to support controlled dispersal of seeding agents.
Built on a VTOL large fixed-wing platform, the CW-80E combines long endurance with heavy payload capacity for extended atmospheric missions. The system supports a maximum payload of up to 25 kg and can remain airborne for up to 480 minutes (approximately 8 hours), depending on configuration, enabling wide-area and long-duration operations.
With a maximum takeoff weight of 100 kg and a wingspan of 5 m, the CW-80E UAV is designed for large-scale deployment scenarios. It offers an operational radius of up to 100–200 km, allowing coverage of expansive target regions within a single mission.
The platform cruises at approximately 100 km/h and can operate at altitudes of up to 5,000 meters. It is engineered to perform in temperatures ranging from -20°C to 55°C and in wind conditions of up to around 17 m/s, supporting deployment in complex and high-altitude environments.
According to the company, the CW-80E supports multiple applications, including rainfall and snowfall enhancement, hail suppression, and forest fire prevention. Its VTOL capability allows deployment in areas with limited infrastructure or challenging terrain, where conventional aircraft operations may be constrained.
The system improves operational efficiency and safety by reducing reliance on manned aircraft and enabling remotely executed missions with precise payload activation. Integrated flight control and payload management systems further support consistent execution under variable atmospheric conditions.
The launch reflects continued expansion in the use of medium- or large-sized UAV for environmental management and atmospheric intervention, as agencies seek more flexible and scalable tools for weather-related operations.
