  • Patent number: 8973450
    Abstract: The present invention controls rolling motion of a vehicle by eliminating the detrimental influence of gyro moment on the motion of the vehicle and actively using gyro moment generated by a flywheel constituting an energy storing device. The invention relates to an attitude control device for a vehicle mounted with a flywheel as an energy storage device, the flywheel being pivotally supported about first and second axes mutually orthogonal with each other, the flywheel being mounted on a body of the vehicle such that the first axis extends in a front-rear direction of the body, the attitude control device comprising locking means for locking movement of the flywheel about the first axis, wherein a rolling motion of the vehicle is controlled by locking the movement of the flywheel about the first axis using said locking means.

  • Patent number: 8876077
    Abstract: A spherical orienting device includes a base, first and second actuation shafts, an orientable device, an inner member, a middle member, and an outer member. The first and second actuation shafts are rotatably held by the base for rotary actuation about first and second actuation axes, respectively, which intersect orthogonally at a spherical center of rotation. The orientable device is supported by first and second revolute support joints which are disposed for rotation about an orientation axis of the orientable device and a support axis, respectively. The inner member is fixed to the first actuation shaft and linked to the second support joint. The middle member is inwardly linked to the first support joint and outwardly linked to a middle revolute joint disposed for rotation about a linkage axis. The outer member is fixed to the second actuation shaft and linked to the middle revolute joint.

  • Patent number: 8468902
    Abstract: The present invention relates to a reusable device for securely holding at least one fragile object against a functional surface solidly fixed to the structure of a satellite or spacecraft during at least one operational phase relating to this satellite, making the objects thus held more accessible and intervention on these objects easier, while at the same time preventing damage to these objects under the effect of sudden accelerations, both during this (these) operational phase(s) and while the hold is being established or while the hold is being released. The device according to the invention is characterized in that it comprises a rigid structure which partially grips this (these) object(s) and which supports at least one fixed jaw and at least one moving jaw substantially facing the fixed jaw(s), the object being immobilized between the fixed jaw and the moving jaw throughout the period of firm holding.

  • Publication number: 20100018333
    Abstract: A precessional device having independent control of the output torque generated by the device and the oscillation rate of the device is disclosed. The device comprises a rotor supported by an axle wherein the ends of the axle are supported by a circular race. The circular race is rotatable, and may be driven by a motor or other means, thereby controlling the oscillation rate of the device independently of the output torque arising from the rotation rate of the rotor. The motor may be controlled by a control program that adjusts the rotation rate of the circular race to modify the shape of the resistance curve.

  • Patent number: 7561947
    Abstract: Methods and apparatus are provided for reorienting control moment gyros (CMGs) to compensate for CMG failure or change in spacecraft (S/C) mass properties or mission. An improved CMG comprises a drive means for rotating the CMG around an axis not parallel to the CMG gimbal axis. Releasable clamps lock the CMG to the spacecraft except during CMG array reorientation. CMGs arrays are combined with attitude sensors, a command module, memory for storing data and programs, CMG drivers and sensors (preferably for each CMG axis), and a controller coupling these elements. The method comprises determining whether a CMG has failed or the S/C properties or mission changed, identifying the working CMGs of the array, determining a new array reorientation for improved spacecraft control, unlocking, reorienting and relocking the CMGs in the array and updating the S/C control parameters for the new array orientation.

  • Patent number: 7197958
    Abstract: An energy storage flywheel system includes a flywheel assembly that is rotationally mounted in a housing assembly, and one or more actuator assemblies. The actuator assemblies are configured to selectively engage and disengage the flywheel assembly. When the actuator assemblies engage the flywheel assembly, the actuator assemblies provide support for, and inhibit rotation of, the flywheel assembly. When the actuator assemblies disengage the flywheel assembly, the actuator assemblies no longer support the flywheel assembly, and no longer inhibit its rotation.

  • Patent number: 7124656
    Abstract: Provided is a gimbal mechanism comprising a support stand, an outer frame and an inner frame. The support stand includes a spaced pair of L-shaped legs comprising a first member having at least one first slot formed therethrough. The outer frame is nested within the support stand and comprises outer frame sides joined to outer frame ends. Each one of the outer frame sides is pivotally engagable to the first slot of an adjacent one of the first members such that the outer frame is selectively angularly and laterally positionable relative to the support stand. The inner frame is nested within the outer frame and comprises inner frame ends joined to inner frame sides. Each one of the inner frame ends is pivotally engagable to an adjacent one of the outer frame ends such that the inner frame is selectively angularly adjusted relative to the outer frame about an inner frame axis.

  • Patent number: 6598492
    Abstract: A passive caging system for use in gyro-stabilized sensor platforms and the like, employing a pneumatic dashpot in place of automatic caging gyro brakes, pin-locking devices, springs, fluid damped pistons, or air bladders. A pneumatic dashpot in combination with a normally closed solenoid valve provides effective damping of shock forces while the system is in the unpowered state. When power is applied to the system, the solenoid valve is open and unrestricted movement of the sensor platform is enabled.
