Abstract: A load-sensing strut has a main body (26) having a longitudinal loading axis (A) along which an applied load is transmitted, and a load sensing member (38) arranged to carry at least a portion of the applied load when the load is within a predetermined range, wherein the load sensing member (38) includes at least one load sensor (46) generating a load signal. The strut also has a load alleviation member (36) arranged to reduce the portion of the applied load carried by the load sensing member (38) when the applied load is outside the predetermined loading range. Consequently, the load sensors exhibit greater sensitivity to incremental changes in the applied load within the predetermined range, yet the strut provides high strength and is capable of reacting to very high loads outside of the predetermined range. The strut may be used in actuating aircraft control surfaces in a high-lift system.

The fiber optic rotary joint is capable of transmitting the optical signal across the interface with reduced jitter.

Abstract: A power-off brake for stopping a rotating shaft comprises a solenoid including a coil and armature, an opposing plate axially spaced from the armature, and a ball carrier rotor between the armature and opposing plate. The ball carrier rotor rotates with the shaft and carries spherical balls in recesses angularly space about the shaft. The armature and opposing plate have respective braking surfaces. In one embodiment, at least one braking surface is ramped to urge the plurality of balls radially outward against an internal surface of a surrounding outer race as the armature is forced toward the opposing plate under spring loading when current to the solenoid coil is shut off. In another embodiment, the braking surfaces are not ramped, such that the balls are merely clamped between the braking surfaces upon solenoid deactivation. Increased rolling friction stops rotation of the ball carrier rotor and the shaft without problematic wear.

Abstract: A ball-detent torque-limiting assembly has breakout means for maintaining an axial separation distance between opposing pocketed surfaces of the assembly once the primary balls of the assembly have rolled out of their pockets, wherein the axial separation distance maintained by the breakout means is at least as great as the diameter of the balls. The breakout means may include a plurality of secondary balls deployed in a breakout event. The breakout means assumes the axially directed spring load that urges the opposing pocketed surfaces together, thereby preventing the primary balls from entering and exiting the pockets in quick and violent succession following breakout and avoiding damage to the torque-limiting assembly. The torque-limiting assembly is resettable by counter-rotation following a breakout event.

Abstract: A rotary valve comprises a bushing and a cylindrical spool rotatably received by the bushing. The rotary valve avoids redundant control edge pairs by having exactly one first supply edge pair (P-C1) for controlling a first fluid supply path, exactly one second supply edge pair (P-C2) for controlling a second fluid supply path, exactly one first return edge pair (C2-R1) for controlling a first fluid return path, and exactly one second return edge pair (C1-R2) for controlling a second fluid return path. A first angle between the first supply edge pair and the first return edge pair, and a second angle between the second supply edge pair and the second return edge pair, are each greater than or equal to 120 degrees and less than 180 degrees. Geometric simplicity is achieved by tolerating a limited degree of force imbalance in valve operation.

Abstract: A power spring passively applies tension to a cable connected to an aircraft refueling boom. The power spring has a first end engaging a fixed arbor and second end engaging a rotatable spooling drum around which a portion of the cable is wound. The power spring biases the drum to rotate in a winding direction to apply tension to the cable, and the power spring stores energy when the drum rotates in an unwinding direction. The power spring may be located inside the drum or outside the drum. The drum may be actively driven by a motor that may be uncoupled from the drum to permit freewheeling rotation of the drum, wherein the power spring continues to apply tension to the cable. The invention eliminates reliance on one or more powered motors for removing unwanted slack in the cable.

Abstract: A force-limiting rotary lock (20) for a shaft (21) mounted on a housing (22) for rotational and axial movement relative thereto, broadly includes a lug member (28) provided on the shaft, and a pawl (51) mounted on the housing. The pawl is movable relative to the housing between first and second positions. The pawl is operatively arranged to engage the lug when the pawl is in its first position (shown in FIG. 3) to prevent further rotation of the shaft in one angular direction, and to be disengaged from the lug when the pawl is in its second position (shown in FIG. 2) to permit rotation of the shaft in either angular direction. A cam (25) is mounted on the shaft, and a follower (49) is mounted on the housing for selectively moving the pawl between the first and second positions when the shaft is axially displaced from its predetermined position. When the shaft is axially displaced from its predetermined position and the pawl engages the lug, the shaft will be prevented from rotating further in the one angular direction.
