Abstract: A linear actuator for a flight control surface including at least one electric motor, a threaded shaft rotationally driven via the at least one motor about a threaded shaft pivot axis, first and second threaded nuts axially displaced via rotation of the threaded shaft, and an output shaft coupled to the threaded shaft, such that axial displacement of the first and second threaded nuts rotates the output shaft about an output shaft pivot axis that is substantially parallel with the threaded shaft pivot axis. Rotation of the threaded shaft in a first rotational direction via the at least one motor prompts movement of the first and second threaded nuts axially toward each other. Further, rotation of the threaded shaft in a second rotational direction opposite the first rotational direction via the at least one motor prompts movement of the first and second threaded nuts axially away from each other.
