摘要：An electromechanical actuator (“EMA”) is provided with redundant load pathsfor driving the actuator stroke. The EMA includes a rotatable screw, a nut mated with thescrew and having an external toothed surface, and a rotatable spline member having a

splined surface engaging the external toothed surface of the nut. An actuator rod iscoupled to the nut for linear movement with the nut. A first motor is operable to rotatethe screw relative to the nut to cause the nut to travel linearly along the screw, and asecond motor is operable to rotate the spline member and nut such that the nut travelslinearly along the screw. Consequently, the actuator rod moves linearly by operation ofthe first motor alone, by operation of the second motor alone, and by simultaneousoperation of the first and second motors. A no-back device may be incorporated intoeach load path.
