Solution Overview KEEL PLUS combines the A10XL propulsion system with the D30 single-hook release device to form a 30 kg-class aerial transport and precision-release platform for industrial operations. It provides rapid aerial access where roads are blocked, terrain is difficult, or ground transport is inefficient. Mission Capabilities • Transport emergency supplies, tools, spare parts, and support equipment up to 30 kg • Perform remotely controlled single-hook release at designated coordinates or route waypoints • Deliver supplies across mountains, forests, islands, worksites, and disaster areas • Lift compact equipment, cables, and maintenance materials for power, energy, and engineering operations • Deploy ropes, rescue equipment, communications devices, and firefighting supplies • Support material transfer and equipment distribution in agriculture, forestry, and livestock operations Applicable Industries Emergency response and firefighting, power and energy, construction and mining, mountain logistics and industrial parks, agriculture and forestry, islands, and remote-area support. Operating Scope and Efficiency A maximum speed of 18 m/s supports rapid response, while up to 25 minutes of flight time suits short- to medium-range point-to-point transport, recurring resupply, and precision delivery within approved airspace. Actual operating radius depends on payload, altitude, wind, temperature, battery reserve, and regulations. Platform Capability Maximum payload is 30 kg, maximum takeoff weight is 55 kg, and the airframe and propulsion kit weighs 12 kg. A high-energy, high-rate battery pack and redundant power architecture improve reliability. CAN + PWM interfaces and modular design support rapid payload integration and maintenance. D30 Single-Hook Release D30 uses the same proven exterior architecture as D20 and is configured for 30 kg-class missions. Release timing can be controlled through the flight controller or ground station for waypoint-based precision delivery where landing is impractical.
