摘要： A linear actuator (100) includes a housing, a linear output member, and a rotary lock assembly. The linear output member includes a radial groove and is axially movable from a retracted position within the housing. The rotary lock assembly (112) is constrained from axial motion within the housing (104) and includes a rotor (116) and a lock (120). The rotor is capable of rotation from a first to a second position. When the linear output member is in the retracted position, the rotor surrounds the radial groove. When the rotor rotates to the first position, the lock engages the radial groove and prevents axial motion of the output member from the retracted position.

摘要： A locking device includes a shape memory alloy actuator that engages a locking pin to release the pin and unlock the device it is engaging. Upon heating the shape memory alloy member, it returns to a predetermined shape, which has a length shorter than its non-heated length. As the shape memory alloy actuator shortens, it pulls the locking pin at least a pre-determined distance to release the locking pin from engagement with the device it is locking and into engagement with a pin release member. The pin release member holds the locking pin in the unlocked position until the pin release member is moved from engagement with the locking pin. Once moved, the pin release member disengages from the locking pin and the pin is moved back into its original, locked position. The shape memory alloy actuator and pin release member are also returned to their original position.

摘要： Oscillation and other disturbance damping is provided for a system having a load driven by an electric motor. Damping is achieved using feedback in an active mode, where power is supplied in a normal operation mode of the electromagnetic actuator. A gear train or other mechanical advantage device is connected between the electromagnetic actuator output and a load, to form an electromagnetic actuator. Feedback is provided by measured force or torque transmitted between the actuator and load mass. In active damping, a high pass filter is used to receive feedback signals and filter out low frequency feedback. The motor coils of the motor are shorted, such as by using a switch. The induced motor current acts to inhibit load oscillations. A number of resistors are in the short circuit to tailor the damping characteristics of the motor.

摘要： A torque motor has a mechanical reference member, an armature, and a field assembly. The field assembly includes field pole pieces defining a pole opening, and the armature is mounted to the mechanical reference member for rotation about a motor axis and extends into the pole opening with respective gaps to the field pole pieces. The field assembly is secured to the mechanical reference member and spaced therefrom by elastically deformable flexures, deformed sufficiently to locate the armature at a predetermined position within the pole openings with corresponding lengths of the gaps. During manufacture, a load can be applied to move the field assembly relative to the mechanical reference member against the deformation force of the flexures to locate the pole opening relative to the armature pole piece such that the gaps of desired lengths are formed.

摘要： A shift lock assembly includes a drive member carried by a drive shaft and configured to rotatably couple to a drive motor and a shift mechanism disposed between the drive member and a ground plate, the shift mechanism configured to move between a first position and a second position relative to the drive member and the ground plate. When disposed in the first position, the shift mechanism is configured to couple the drive shaft to the ground plate and decouple the drive shaft from the drive member to allow rotation of the drive member relative to the drive shaft. When disposed in the second position, the shift mechanism is configured to couple the drive shaft to the drive member and decouple the drive shaft from the ground plate to allow rotation of the drive shaft in response to rotation of the drive member.

摘要： A multi-stage fin deployment assembly (26) includes a rotary actuator (30) configured to release a first spring-loaded stage (32) that, when deployed, releases a second spring-loaded stage (34) to deploy a set of deployable member (24) or fins. By chaining these spring-loaded stages (32,34) together, a relatively small input force, as provided by the rotary actuator (30), causes the second spring-loaded stage (34) to generate a relatively large output force on the fins (24). This multistage force magnification makes it possible for the deployment assembly (26) to utilize smaller actuators (30) that require less power and take up less space, compared to conventional locking mechanisms.

摘要： A slot cover (36) actuation assembly controls access through a slot (26) on a projectile. The slot cover (36) actuation assembly includes a slot cover (36), a fastener (38) (e.g., a screw), and an actuator (40) (e.g., a squib device). The fastener (38) is arranged to position the slot cover (36) at an installation position on the projectile. The slot cover (36) covers the slot (26) on the projectile when the slot cover (36) resides at the installation position. The actuator (40) is arranged to release the slot cover (36) from the installation position on the projectile. The slot cover (36) uncovers the slot (26) on the projectile when the actuator (40) releases the slot cover (36) from the installation position on the projectile, thus allowing a control surface member (34) (e.g., a fin) to deploy.

摘要： A hydraulic actuator is configured to provide redundant boost control to an aircraft within approximately the same space required by a single hydraulic cylinder. The hydraulic actuator includes a housing and a piston assembly disposed within the housing. The piston assembly includes a ram, a first piston secured to the ram, and second and third pistons disposed on the ram such that the second and third pistons are translatable relative to the longitudinal axis pf the ram. The pistons form two hydraulically separate actuator cylinders within the space required by a single cylinder which results in a reduction in the weight and size of the hydraulic actuator.

摘要： Two or more flow control valves (140a, 140b) may be used to provide redundant flow control for a hydraulic actuator (111) or servoactuator. The flow control valves include a sleeve (142a, 142b) control spool (146a, 146b). Under normal operating conditions, each bypass control spool is stationary relative to the sleeve and the flow control valve functions as a four-way hydraulic flow control valve. Each flow control valve is connected to a bypass-shutoff valve (160a, 160b) including a bypass spool that is moveable from a shut-off position to a bypass position. Upon supply pressure failure to one flow control valve, the bypass spool moves to the bypass position, reducing pressure in the corresponding actuator piston chambers. When a primary control spool (146a, 146b) becomes jammed, the corresponding bypass control spool moves within its sleeve (142a, 142b) allowing a bypass groove to port control pressure to the return line, thereby reducing pressure in the corresponding actuator piston chambers.
