ABSTRACT:
Aircraft that use a shape memory alloy to extend or retract landing gear are provided. The present invention includes aircraft that contain a first retractable landing gear and a first shape memory alloy. The first retractable landing gear in the aircraft may be moveable from a first position to a second position while the first shape memory alloy may be changeable from a first configuration to a second configuration, the first shape memory alloy being in physical communication with the first retractable landing gear. Aircraft in accord with the present invention may also include a lock positioned to secure the first retractable landing gear in a retracted position and/or a second retractable landing gear coupled to the aircraft. This second retractable landing gear may also be moveable from a first position to a second position.
