摘要： An apparatus includes a housing which defines a longitudinal axis; a positioning element which, relative to the housing, translates linearly along the longitudinal axis; and a rotational member which, relative to the housing, rotates about the longitudinal axis as the positioning element translates linearly along the longitudinal axis. The rotational member defines a helix to receive torque from the positioning element as the positioning element translates linearly along the longitudinal axis. The apparatus further includes a first sensor assembly to detect minor angular displacement of the rotational member (e.g., less than 360 degrees). The apparatus further includes a second sensor assembly to detect major angular displacement of the rotational member (e.g., a number of full 360 degree rotations). Such detection is capable of identifying a full angular displacement of the rotational member in response to linear translation of the positioning element from an initial position to a sensed position

摘要： A method of locking a linear output member in a retracted position within a linear actuator, where the linear output member is capable of axial motion within a housing of the linear actuator, includes rotating a generally tubular rotor disposed within a rotary lock assembly of the actuator to a first rotor position, and shifting a lock capable of radial displacement within the rotary lock assembly based on rotating the rotor to the first position. The lock engages a radial groove of the linear output member when the linear output member is in a retracted position. The rotary lock assembly is constrained from axial motion. The radial groove of the linear output member includes an axially angled, substantially planar surface. The lock is configured to include an axially angled surface shaped complimentary to the axially angled, substantially planar surface of the radial groove.

摘要： In some aspects, an aircraft engine thrust reverser lock system includes a pin-capturing member. The pin-capturing member includes a body that is rotatable about an axis defined by a pivot extending through the body. The body includes an interior surface that defines a slot. The slot has an opening that is sized to receive a pin into the slot. One side of the slot includes a protruded sidewall surface that protrudes into the slot toward an another sidewall surface of the slot. The protruded sidewall surface defines an apex between the open and closed ends of the slot. Between the apex and the closed end of the slot, the protruded sidewall surface faces the rotational axis.

摘要： An improved technique for controlling an electro-mechanical actuator combines a sliding mode of control with a second mode of control. An error signal is generated based on the difference between an input position signal and a feedback position signal. When the error signal is above a predetermined threshold, the actuator is controlled in the sliding control mode. When the error signal is below the predetermined threshold, the actuator is controlled in the second control mode. The combination of the sliding control mode with the second control mode yields a robust controller that can tolerate large parameter variations and uncertainties without sacrificing precise steady state tracking.
