Abstract
A stored energy system for opening aircraft doors, especially useful in connection with emergency slide compartment doors. The system includes a mechanical energy door opening mechanism and a mechanical energy door latch mechanism leaving a latch actuator. Both the latch actuator and the door opening mechanism each have resident stored mechanical energy means wound by rotating an input shaft. Discharge of the energy is prevented by restraining a reverse rotation of the input device, thus enabling the mechanical energy means to be wound in only one direction. When the aircraft door is to be opened, the latch actuator delatches the door and subsequently the door opening mechanism employs a pivotably mounted arm to open the door.
