FAULT-TOLERANT ACTUATOR ASSEMBLY, AND METHOD OF MOVING A MEMBER RELATIVE TO A SUPPORT

摘要

A fault-tolerant actuator assembly (20) is mounted on a support (21) for controllably moving a member (22) relative to the support. The actuator assembly includes a first actuator(24) having a first end connected to the support and having a second end arranged for controlled movement relative to its first end and connected to the member at a first location ((x3- x3); and a second actuator (25) having a first end connected to the support and having a second end arranged for controlled movement relative to the first end and connected to the member at a second location (x4-x4 )aced from the first location; such that the actuators may be operated either cooperatively or independently to control movement of the member relative to the support.
