  • Patent number: 6009669
    Abstract: An aircraft door adapted to substantially seal with a door frame. The aircraft door is provided with an edge portion which is formed to engage the door frame. The edge portion has a sealed position wherein the edge portion is engaged with the door frame. The edge portion further has an unsealed position wherein the edge portion is spaced from the door frame. The aircraft door is further provided with a substantially rigid door body and an elastic portion interposed between the door body and the edge portion. The elastic portion is selectively expandable and compressible for permitting movement of the edge portion between the sealed and unsealed positions. The aircraft door is further provided with an actuator device which mechanically couples the door body with the edge portion for selectively moving the edge portion between the sealed and unsealed positions. The actuator device comprises a shape memory metal material having a predetermined transition temperature.
