Abstract:
1. An actuator for actuating movement of a control surface relative to a structure, comprising: a first load transfer assembly comprising a first assembly, the first load transfer assembly connectable between a control surface and a structure, the first load transfer assembly providing a first load path from the control surface to the structure; a second load transfer assembly comprising a second assembly, the second load transfer assembly connectable between the control surface and the structure, the second load transfer assembly providing a second load path from the control surface to the structure, and wherein the second assembly is less efficient at transferring motion between the structure and the control surface than the first assembly; a drive mechanism for driving the first assembly and the second assembly; and a coupler disposed between the drive mechanism and the second assembly and having a closed state in which the drive mechanism is coupled to the first assembly and second assembly such that the first assembly and the second assembly are synchronously driven, and an open state in which the drive mechanism is decoupled from the second assembly so that second assembly can inhibit movement of the control surface.
