摘要:
A system and method are provided for supplying haptic feedback to, and for electronically linking, pilot and co-pilot user interfaces. The user interface haptic feedback and linking are implemented using either force or position data. If the force or position data become unavailable, then position or force data, respectively, are used to implement the user interface haptic feedback and linking.

A controllable motor includes a rotor. A first stator winding set is operable, upon being energized, to generate and apply a first torque to the rotor. A second stator winding set independent of the first stator winding set is operable, upon being energized, to generate and apply a second torque to the rotor. A motor control is coupled to the first and second stator winding sets. The motor control is operable to selectively energize one of the first or second stator winding sets to thereby generate and apply one of the first or second torques to the rotor, and simultaneously energize both the first and second stator winding sets to thereby generate and apply a third torque greater than the first or the second torque.

An actuation assembly is provided. The actuation assembly includes a casing, a plurality of linear actuators coupled to the casing, each of the linear actuators having first and second components and being configured to move the second component thereof relative to the first component thereof along a respective first axis, and a plurality of translational member sets, each being coupled to the second component of a respective one of the linear actuators and the casing and being configured such that when the second component of the respective linear actuator moves along the respective first axis, a selected portion of the translational member set moves substantially along a respective second axis.

Electromechanical actuators (EMAs) include an output disposed at a location that is axially central between two EM devices. The EMAs include either one or two motors and an output mechanism. The motors are adapted to be energized and are operable, upon being energized, to either generate torques about a first axis or drive forces along a first axis. The output mechanism is responsive to the torques or forces to translate along a second axis that is perpendicular to the first axis.

An actuator device configured to provide a large stroke output. The actuator device including a first piezo element and a second piezo element disposed within a housing. The first piezo element and the second piezo element having a combined long dimension and a height, wherein the long dimension is greater than the height. A fluid region containing a hydraulic fluid is defined in the piezo actuator element at a mid-point of the long dimension and extending parallel with the height of the piezo actuator element. An amplifier including a piston element is slidably coupled to the fluid region. The amplifier provides a large stroke output of the piston element at a mid-point of the long dimension of the piezo actuator elements in response to displacement of the fluid within the fluid region when under the influence of an applied voltage.

摘要:
An aircraft flight surface control system and method simultaneously provides the benefits of both an active/active system architecture and in active/standby system architecture. The system is preferably implemented using hydraulic actuator assemblies and electromechanical actuator assemblies coupled to the same flight control surface. During normal system operations the electromechanical actuator assemblies are energized to supply a relatively minimal force to associated flight control surfaces. In effect, the electromechanical actuators, although energized, may be pulled along by the associated hydraulic actuator assemblies, until needed. Thus, the electromechanical actuator assemblies are controlled in a manner that closely resembles the active/standby architecture.

An aircraft flight control surface actuation system includes a plurality of flap actuators, and a plurality of slat actuators. The actuators receive actuator position commands from an actuator control unit and, in response, move flaps and slats between stowed and deployed positions. The flight control surface actuator control unit includes a plurality of independent actuator control channels. One or more of the independent actuator control channels is coupled to both a flap actuator and a slat actuator, and is configured to selectively supply the actuator position commands thereto.
