Cloud Seeding UAV Concept
RM-120 DroneDash RainMaker
The RM-120 is a DroneDash concept exploring unmanned cloud-seeding operations using modular payloads and precision dispersal. Derived from the GDA80 multirotor configuration, it brings a heavy-lift airframe idea together with mission sensing, metering and release systems.
Concept under development. The RM-120 is not a production or commercially deployed aircraft. Payload, endurance, weather protection and operating altitude are subject to engineering and flight validation.
Payload architecture
Cloud Seeding Payload System
Proposed modular payload enclosure with removable access panels and pressure-equalisation venting. Internal storage and dispensing configuration will depend on the selected seeding medium.

Aircraft architecture
Key Systems
Proposed subsystems are shown as elements of the engineering concept, not as certified production equipment.
Meteorological sensor suite
A proposed sensor set for observing local atmospheric conditions during mission planning and flight.
Weatherproof avionics
An avionics enclosure concept designed around exposure to demanding atmospheric environments.
Radar altimeter
A proposed independent height-sensing input for situational awareness within the flight-control architecture.
Dispersion nozzles
Metered outlets intended to distribute selected seeding media in a controlled release pattern.
Modular payload enclosure
A proposed reinforced aluminium enclosure with removable access panels and pressure-equalisation venting.
Mission-configurable ideas
Modular Seeding Payloads
The payload bay is conceived around interchangeable dispensing approaches. Media selection, handling and release would depend on mission requirements, regulation, atmospheric assessment and validation.
Intended mission sequence
Operational Concept
Cloud seeding is conditional on suitable atmospheric conditions. This concept does not imply guaranteed rainfall or guaranteed enhancement.
- 01
Deploy to target cloud area
Plan and navigate an unmanned mission toward an assessed target area.
- 02
Release near the appropriate cloud region
Use the selected payload concept to release seeding material at an intended location.
- 03
Support cloud microphysics
Support processes intended to enhance precipitation under suitable conditions, without guaranteeing an outcome.
