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 translation: 动力弹簧被动地对连接到飞机加油站的电缆施加张力。 动力弹簧具有接合固定心轴的第一端和接合可旋转绕线筒的第二端，绕线轮的一部分围绕该缠绕滚筒缠绕。 动力弹簧偏压滚筒以沿卷绕方向旋转，以向拉索施加张力，并且当滚筒沿展开方向旋转时，动力弹簧储存能量。 动力弹簧可以位于滚筒内部或滚筒外部。 滚筒可以由马达主动地驱动，该马达可以与滚筒脱开，以允许滚筒的自由旋转，其中动力弹簧继续向拉索施加张力。 本发明消除了对一个或多个动力马达的依赖，以去除电缆中的不必要的松弛。

Abstract: A stop module for non-jamming end-of-stroke stoppage of a rotary drive actuator includes timing gears to articulate a stopping pawl, and a low inertia, deformable stopping disk arranged to safely dissipate excess rotational kinetic energy of the rotary actuator. The stop module does not rely on friction to stop and dissipate the excess kinetic energy, but instead relies on predictable deformation of a metallic stopping disk which may be provided in a stopping cartridge of the stop module. Use of a deformable element to dissipate excess energy allows the disclosed stop module to be lighter and smaller than conventional end-of-stroke stopping mechanisms.

Abstract: A low-cost method of manufacturing a composite tube assembly having a composite fiber tube connected to metallic end fittings includes placing at least one end fitting on a mandrel, the end fitting including a grip region having a plurality of external surfaces, wrapping a fiber tow around the grip region of each end fitting and the mandrel to form a fiber-wrapped assembly, curing the fiber tow, and removing the mandrel to yield a completed tube assembly. The method may include positioning a plurality of compression inserts around the grip region after some of the fiber tow has been wrapped around the grip region, and wrapping additional fiber tow around the compression inserts and the grip region. The compression inserts may have a rounded outer surface such that an end portion of the tube wound around the compression inserts has a round outer cross-sectional shape.

Abstract: A torque transmission apparatus incorporates a differential gear system and a stationary sensor connected to the differential gear system for measuring output torque. The stationary sensor may be connected to a measurement output element of the differential gear system by a torsionally compliant measurement member, wherein the stationary sensor measures torsional deformation of the measurement member. The torsional deformation may be measured directly, or it may be measured following amplification by a gear train. A rotary position sensor may be used as the stationary sensor. Alternatively, the stationary sensor may be connected to the measurement output element of the differential gear system by way of a rigid measurement member, wherein the stationary sensor measures force applied by the measurement member. In this alternative, a force sensor may be used as the stationary sensor.

Abstract: An apparatus for connecting a rotational drive member to a rotational driven member brakes rotation when either the torque transmitted between the members exceeds a predetermined torque limit or the rotational speed of the drive member exceeds a predetermined rotational speed limit. The apparatus includes a torque limiter configured to actuate a braking mechanism or disconnect transmission when the torque limit is exceeded, and an over-speed governor configured to trigger the torque limiter when the rotational speed of the input element exceeds the rotational speed limit. The over-speed governor may trigger the torque limiter by reducing the torque limit of the torque limiter, or by introducing rotational drag in the apparatus to increase transmitted torque.

Abstract: A rotary lock apparatus comprises a structural ground and a shaft rotatable about a shaft axis relative to the structural ground, wherein the shaft includes a detent portion. First and second locking components are displaceable along the shaft axis in opposite directions to cause the detent portion to be engaged and coupled to the structural ground in a manner preventing rotation of the shaft about the shaft axis. The locking components are actuated through a combined displacement distance and are configured such that at least one of the first and second locking components positively causes the shaft to be engaged and coupled to the structural ground to thereby lock the shaft against rotation.

Abstract: A low-cost method of manufacturing an all-composite composite torque tube includes winding fiber tow around a cylindrical mandrel and a plurality of eyelet forms held by an end fixture on the mandrel, whereby a flanged end coupling is formed. The method may include the use of a pre-woven composite fiber end sleeve configured to define the flanged end coupling. The wound fiber, and the end sleeve, are cured together in a single step. Metal eyelets may be installed in the bolt holes.

Abstract: A stop mechanism for a drive system includes a one-way clutch, a brake, a stop feature, and a linkage. The one-way clutch couples with a drive shaft of the system when the drive shaft is rotating in a first direction but not in an opposite direction. The brake is connected to the drive shaft through the first one-way clutch and is operable to stop drive shaft rotation in the first direction. The stop feature is carried by an output element driven by the drive shaft and actuates the linkage to operate the first brake when the output element reaches a predetermined limit position when moving in a direction corresponding to the first drive direction of the drive shaft. A bidirectional stop mechanism is provided by adding a second one-way clutch, a second brake, and a second stop feature arranged to act in the opposite rotational direction of the drive shaft.
