Patent granted for uav door release system with parachute deployment
A recently granted patent (Publication Number: US11981429B2) describes a system designed to secure and control an unmanned aerial vehicle (UAV) door through a latching mechanism. The system includes at least two radio modules in communication with a ground control station, burn wires attached to the radio modules, and latches to secure the UAV door. The burn wires are activated by a burn signal from the ground control station, melting a string that connects the latches, allowing for controlled separation of the UAV door from the rest of the vehicle.
Additionally, the system incorporates a parachute that deploys when the door is separated, causing the UAV to spiral down towards the ground. The patent also details a method for implementing this system, involving receiving burn signals, toggling backup batteries, and melting the string to separate the UAV door. The method includes steps for deploying the parachute and inducing a controlled rotation of the UAV to exit its current flight pattern. The system's design and method aim to provide a safe and controlled way to manage UAV doors and facilitate controlled descent in emergency situations.
