The DJI M30 drone parachute system is developed based on the DJI SDK and the APS intelligent parachute deployment mechanism. By fusing flight data from both the drone sensors and the parachute’s onboard sensors, the system gains accurate insight into real-time flight attitude. When abnormal conditions occur, the APS algorithm triggers propeller stop and parachute deployment commands within milliseconds, ensuring safe deceleration and controlled landing at an average descent speed of 4.6 m/s.

• DJI SDK Development and Full Compatibility

  Developed on the DJI SDK platform, the system is fully compatible with the DJI Matrice 30 and Matrice 30T flight platforms.

• Redundant IMU and Barometer Design

  To enhance system reliability, the OWL-M30 parachute adopts industry-standard redundant IMU and barometer architecture. Millisecond-level switching ensures the backup sensor can immediately take over under any complex scenario, guaranteeing continuous and accurate flight-state recognition.

• Two-Way Data Fusion with the Drone

  The M30 and parachute system exchange and fuse attitude, altitude, motor status, and flight-state data in real time. This fusion enables accurate assessment of abnormal flight behavior for precise emergency decision-making.

• Reusable Modular Structure

  The system features a modular design that separates the main controller from the parachute module. After deployment, operators only need to replace the parachute module, making the system cost-efficient and easy to restore for continued use.

• Quick-Release Installation

  Tool-free quick-release mounting allows for fast installation and removal, reducing operating time and improving field efficiency.

• APS Intelligent Safety Workflow

  In emergencies, the APS safety system first stops the propellers and then deploys the parachute, preventing secondary hazards such as propeller strikes or entanglement. All actions occur within milliseconds to maximize rescue effectiveness.

• Self-Developed APS Algorithm for Automatic Deployment

  To maximize reliability, the Firefly team continuously conducts tests and simulations under complex failure scenarios. The APS algorithm integrates motor RPM, battery status, attitude, flight mode, and altitude to accurately identify emergencies. When a sudden failure occurs, the system executes a strict sequence: propeller stop → parachute deployment → audio/visual alarm → slow descent, ensuring safe protection of the DJI Matrice 30 series.
