  • Patent number: 8430757
    Abstract: A constant-velocity drive system for an aircraft rotor has a gimbal mechanism and a differential torque-combining mechanism. The gimbal mechanism has gimbals driven in rotation by a rotor mast about a mast axis, the gimbals providing for gimballing relative to the mast about gimbal axes generally perpendicular to the mast axis. The differential torque-combining mechanism is connected to the gimbal mechanism and configured to be driven in rotation about the mast axis by the gimbal mechanism. The differential mechanism is capable of gimballing relative to the mast about the gimbal axes, the differential torque-combining mechanism having an output component attached to a yoke of the rotor for driving the yoke in rotation with the differential torque-combining mechanism.

  • Publication number: 20130098732
    Abstract: A hybrid overrunning clutch includes a metal outer race and a composite outer ring that are each sized and configured such that the metal race generates a preload on the composite outer race throughout the operational temperature of the clutch. The composite outer ring significantly reduces that total weight of the clutch, as compared to a completely metal outer race. The present application further includes a method of assembling the metal outer race and composite outer ring so that thermal expansion of the metal outer race creates the preload in the composite outer ring. The present application also includes a method of designing a hybrid overrunning clutch.

  • Patent number: 8428686
    Abstract: A system and method for monitoring a physiological parameter includes a garment that includes a fabric that exhibits both a light transmission property and a light reflection property. The amount of light transmitted through the fabric relative to the amount of light reflected by the fabric changes when the fabric stretches in response to motion, such as the motion induced by physiological activity (e.g., heart rate). The system includes at least one source of radiation having wavelength(s) in the range of 400 to 2200 nanometers and at least one detector responsive to such incident radiation. The source and detector are associated with the fabric such that the reception of incident radiation by the detector is directly affected by a change in the amount of light transmitted through the fabric relative to the amount of light reflected by the fabric when the fabric stretches.

  • Publication number: 20130092792
    Abstract: The shear bonding method is configured to facilitate bonding of structures in an out-of-autoclave environment. The shear bonding method includes bonding a plurality of frame members to the interior of a tapered tailboom. The frames are located on a bayonet type tool. An adhesive pack is applied to each frame. The bayonet type tool is inserted into the tailboom until the adhesive packs come into contact with the interior walls of the tailboom. Conductive heating tiles are applied to the tailboom. The conductive heating tiles are controlled to achieve and maintain viscosity of the adhesive packs. During this period the bayonet tool is actuated so that the frames are translated in relation to the tailboom. The heating tiles are then controlled to achieve and maintain the adhesive at a requisite curing temperature.

  • Patent number: 8419375
    Abstract: A method of making a rotor yoke includes preparing a cured composite rotor yoke preform on a single-sided curing tool and machining at least one portion of the cured rotor yoke preform to form a rotor yoke. In one embodiment, preparing the cured composite rotor yoke is accomplished by applying successive layers of uncured polymeric composite material to a single-sided tool in a configuration to produce an uncured rotor yoke preform; disposing a semi-rigid caul to an untooled side of the uncured rotor yoke preform; enclosing the uncured rotor yoke preform and the semi-rigid caul by substantially hermetically sealing a vacuum bag to the tool; substantially evacuating a volume defined by the vacuum bag and the tool of air; and heating the uncured rotor yoke preform, sometimes under pressure, to form the cured composite rotor yoke preform.

  • Publication number: 20130089422
    Abstract: The system of the present application includes an adaptive twist system for a rotor blade. The adaptive twist system includes a slider mechanism coupled to a spar and to a skin. The slider mechanism provides structural connectivity between the spar and the skin while also selectively translated the skin relative to the spar, thereby causing the rotor blade to twist. A control system is used to operate the slider mechanism so that the rotor blade is automatically twisted into the optional shape during changes in flight modes.

  • Publication number: 20130087653
    Abstract: A tail boom adapted for counteracting a fuselage torque created by an engine carried by a fuselage of a rotary aircraft. The tail boom is positioned within the rotorwash from the rotary and includes a first side surface contoured to create a low-pressure region of an airfoil and a second opposing side surface contoured to create a high-pressure region of an airfoil. The pressure difference between the high-pressure region and the low-pressure region causes the tail boom to move towards the low-pressure region, resulting in a lateral force opposing the torque on the fuselage.

  • Publication number: 20130081843
    Abstract: A bypass assembly varies the hydraulic motor revolutions per minute (rpm) of a hydraulically driven tool, such as a wrench or a drill. This controls the torque of a driven mechanical mechanism, such as used on an impact wrench. The tool includes a body having a supply channel capable of being connected a source of fluid, a bypass spool channel in fluid communication with the supply channel, and a return channel in fluid communication with the bypass spool channel via a port and in fluid communication with the source. A bypass spool seats in the bypass spool channel. The bypass spool can be rotated to three discrete positions within the bypass spool channel to provide three different settings of revolutions per minute (rpm) of the gear motor.
