An electromechanical actuator comprises: a motor; a gearbox; an anti-extension device mounted between the motor and the gearbox. The motor and anti-extension device are mounted on a housing of the actuator. The actuator further comprises a screw shaft; a nut mounted on the screw shaft; an output rod connected to the nut, the output rod having a linear range of motion defined between full extension of the output rod at a first end point (A) and full retraction of the output rod at a second end point (C). The screw shaft, nut, and output rod are located in a cavity of the housing. The output rod and nut are held against rotation relative to the housing, such that rotation of the screw shaft drives the output rod to move linearly within the housing.

Spoiler actuator

An electromechanical actuator (EMA) assembly. The assembly includes: an electric motor; a drive shaft in engagement with the motor to be rotated about a shaft axis by operation of the motor; an output ring around the drive shaft, the output ring caused to rotate with rotation of the drive shaft, the output ring configured to be connected, in use, to a load to be driven by the EMA; a gear assembly between the drive shaft and the output ring to transmit rotation of the drive shaft to rotation of the output ring at a gear ratio. The gear assembly comprises a sun gear in engagement with the drive shaft, an outer gear in engagement with the outer ring, and planetary gears rotating between and transmitting rotation between the sun gear and the outer gear; and a planet carrier plate mounted to the planetary gears to rotate with the planetary gears.

Rotary EMA

An actuation system for a control surface for an aircraft includes a first, second, third and fourth actuator, a first and second bell crank, and at least one push pull rod system. Each of the first and second bell cranks comprises a first and a second crank arm, the first and second crank arms intersect with and are joined to each other at an intersection, the first and second crank arms extend from the intersection at an angle to each other, the first bell crank is pivotally connected to the sub-structure by a first pivot extending through the first bell crank's intersection, and the second bell crank is pivotally connected to the sub-structure by a second pivot extending through the second bell crank's intersection.
