AOISUN AD2 Airdrop Device Enhances Emergency Relief Efficiency in Mountainous Disaster Response

In 2025, a regional emergency response team deployed AOISUN AD2 Two-Stage Airdrop Devices on DJI Matrice 4E drones to deliver critical supplies to isolated communities in mountainous areas affected by landslides. The mission required rapid, precise delivery of medical kits, food, and water to locations inaccessible by road, with tight time windows and variable weather conditions.

• Equipment Integration: The AD2’s screw quick-release design allowed technicians to mount the device to Matrice 4E drones in under 2 minutes per unit. At only 43g, the payload added negligible weight, preserving full flight range for long-distance missions.
• System Configuration: Teams used the DJI Pilot 2 App to set up delivery waypoints, test single-point and one-click full-drop modes, and calibrate the mount position detection feature for reliable release.
• Environment Adaptation: The AD2’s IP44 rating and -10°C to 50°C operating range eliminated concerns over light rain and temperature fluctuations common in the region.

• Dual-Stage Delivery: With 2 independent mounting positions (1kg per stage, 2kg total capacity), each drone carried two types of supplies (e.g., medical kits on the first mount, water pouches on the second). Pilots released payloads sequentially at different drop zones without returning to base, doubling mission efficiency.
• Real-Time Control: Pilots used remote controller buttons to trigger drops manually, with laser aiming guidance ensuring supplies landed within 3 meters of target coordinates—critical for safe delivery to crowded landing sites.
• Multi-Device Compatibility: The E-Port Lite interface allowed simultaneous use of the AD2 with drone searchlights, enabling night operations and low-visibility drops without additional payload weight.

• Efficiency Gains: The team completed 12 airdrop missions in 6 hours, delivering 24kg of supplies to 8 isolated communities—an improvement of 100% over previous single-stage airdrop systems.
• Reliability Metrics: 100% of payloads were released successfully, with zero malfunctions due to the AD2’s durable alloy construction and redundant safety mechanisms.
• Operational Savings: Reduced round-trip flights cut fuel consumption and pilot fatigue, allowing the team to extend operations into the evening and cover additional remote locations.

• Team Testimonial: “The AD2’s lightweight design and dual-stage capability were game-changers. We could carry twice the supplies per flight and still maintain full control over drop timing—something no other payload offered.”
• Key Improvements: The mount position detection feature prevented accidental releases during takeoff/landing, while the ability to use the device with searchlights simplified night operations.
• Scalability: The device’s compatibility with Matrice 3D/4D models allowed the team to deploy additional drones without reconfiguring equipment.

The AOISUN AD2’s combination of ultra-light design, dual-stage flexibility, and seamless DJI integration directly addressed the core challenges of mountain disaster relief: speed, precision, and reliability. By reducing payload weight, expanding delivery capacity, and simplifying multi-device setups, the device enabled the response team to meet mission-critical timelines and deliver life-saving supplies where they were needed most.

For emergency response teams, public safety agencies, and field operations worldwide, the AD2 offers a proven, scalable solution for precision aerial delivery.
