Aircraft door architecture with emergency opening and inflatable evacuation
A newly filed patent (Publication Number: US20240025530A1) describes an innovative aircraft door architecture designed to enhance safety during emergencies. The system includes a door that can be opened manually or through an ejector for emergency situations. An inflatable evacuation device is stored within the door and can be deployed when needed. The system is equipped with an emergency energy source that activates the ejector, inflates the evacuation device, and controls a retaining bar actuator. A control unit manages the system's operation, switching between a nominal state and an emergency state to ensure proper functioning during normal operations and emergencies.
Furthermore, the patent details the control unit's interface for user interaction, allowing for easy arming and disarming of the evacuation device. In the event of an exterior opening of the door, the control unit automatically disarms the device. The system's emergency energy source, which includes an electric secondary cell, is activated by a mechanical trigger connected to the door's opening mechanism. Additionally, the architecture incorporates thermal batteries to power various components, such as the ejector and inflating device. Electrical connectors enable integration with the aircraft's onboard electrical network, ensuring seamless operation and connectivity during emergencies. The system also features an isolation box to manage electrical connections effectively, enhancing overall safety and reliability.
