AI Technical Summary

Technical Problem

Existing drone-borne payload lifting systems suffer from two-body coupling issues between the drone and the payload, as well as problems with the pilot's slow reaction time, when sudden failures occur. This can lead to parachute system failure or failure to drop the payload in time, thus failing to effectively protect high-value payloads.

Method used

Design an integrated safety system for autonomous decoupling and ejection parachute compartment for unmanned aerial vehicle (UAV) payload transport, including an autonomous fault detection unit, a rapid decoupling mechanism, and a payload ejection parachute compartment. The system detects catastrophic faults through an inertial measurement unit, quickly cuts the sling and ejects the parachute, achieving independent rescue of the payload and the UAV.

Benefits of technology

Decoupling the drone from the payload within milliseconds avoids the risks of parachute entanglement and overload, ensuring a safe landing for the payload, improving the survival rate of both the payload and the drone, and reducing accident losses.

Abstract

This invention discloses an autonomous decoupling and ejection parachute compartment integrated safety system for unmanned aerial vehicle (UAV) payload transport. The system includes an autonomous fault detection unit comprising an independent power supply, inertial measurement unit, and microprocessor; a rapid decoupling mechanism for disconnecting the sling connecting the UAV and payload upon receiving a trigger signal; and a payload ejection parachute compartment integrating a parachute and an ejection mechanism for forcibly ejecting the parachute. This invention solves the two-body problem of coupled UAV and payload falling during transport scenarios. Through the system's autonomously triggered rapid decoupling mechanism, the sling is disconnected within milliseconds, separating the interconnected and violently swinging UAV and payload composite into two independent falling units. This disintegration step eliminates the risk of payload entanglement and overload on the UAV's parachute deployment, and also isolates the payload's rescue from complex coupled dynamics, making subsequent independent parachute deployment rescue possible.
